A
Jimmy is an automotive mechanic, but he lost his job a few months ago. He has good heart, but always feared
applying for a new job.
One day, he gathered up all his strength and decided to attend a job interview. His appointment was at 10 am and it was already 8:30. While waiting for a bus to the office where he was supposed ot be interviewed, he saw an elderly man wildly kicking the tyre of his car. Obviously there was something wrong with the car. Jimmy immediately went up to lend him a hand. When Jimmy finished working on the car, the old man asked him how much he should pay for the service. Jimmy said there was no need to pay him; he just helped someone in need, and he had to rush for an interview. Then the old man said, “Well, I could take you to the office for your interview. It’s the least I could do. Please. I insist.” Jimmy agreed.
Upon arrival, Jimmy found a long line of applications waiting to be interviewed. Jimmy still had some grease on him after the car repair, but he did not have much time to wash it off or have a change of shirt. One by one, the applicants left the interviewer’s office with disappointed look on their faces. Finally his name was called. The interviewer was sitting on a large chair facing the office window. Rocking the chair back and forth, he asked, “Do you really need to be interviewed?” Jimmy’s heart sank. “With the way I look now, how could I possibly pass this interview?” he thought to himself.
Then the interviewer turned the chair and to Jimmy’s surprise, it was the old man he helped earlier in the morning. It turned out he was the General Manager of the company.
“Sorry I had to keep you waiting, but I was pretty sure I made the right decision to have you as part of our workforce before you even stepped into the office. I just know you’d be a trustworthy worker. Congratulations!”Jimmy sat down and they shared a cup of well-deserved coffee as he landed himself a new job.

This site , all-birds. com , is about bird watching. Enjoy your browsing. There is much to learn and see.
Bird Watching Equipment
Some items that might make bird watching more enjoyable are binoculars （双目望远镜）, a camera, some kind of system for keeping notes, and maybe a back pack．Birders often keep lists of the birds they see along with notes about the habits．There is some great bird log software that will let you keep records on your computer．For more details on choosing binoculars see our Binocular -Optics page．
Clothes
If you are walking through a wooded area just wear clothes you would wear on any hike or field trip．You are best off wearing clothes with dull colors that mix into the background．Greens, browns, and grays are good．Avoid fabrics that rustle（沙沙响）easily．Depending on the birds you are watching you may want to get rain gear, rubber boots and warm clothing．For birds such as owls that you might look for in the evening a strong flashlight is also handy．
Choosing a Bird Field Guide
Take a good field guide to identify birds．Look for clear color pictures that make it easy to recognize one bird from another．Next to each picture should be detailed descriptions of each bird's anatomy, habits, and what it eats．The guide should have information about what habitat each species uses．Many guides have maps showing the range of different birds along with their migration patterns．
Where and When to see Birds
Learning the habitats of birds in your area will increase the number of birds you see, and make your birding more enjoyable．If you know that Meadow larks are likely to be in open grassy areas, and dippers are forage along stream beds, you may be looking for them if you are in those types of habitats．Edge areas where different types of habitats meet will likely have more species in them．You are more likely to see specific birds at certain times of the day．For example songbirds are easier to see two to three hours after dawn, or just before sunset．This is when songbirds are most actively feeding．Many small birds will be silent or even hidden during the rest of the day．After sunup is the best time to see eagles and hawks．Visibility is best for hunting at this time, and they can soar on the thermal currents from the warmed air．Birds like owls are more likely to be seen in the evening．Many shorebirds and waders rest at high tide and feed when the water rises or falls．
can use less
expensive equipment, then you need for high quality prints.
☆Photographing Birds in Flight
Photographing birds in flight can be fun．Many digital cameras have a tracking function．With these you focus on the bird, and then as you track it the lens will keep focus．
☆Use Your Yard
Choose an open area where the birds will get direct sunlight, showing off their magnificent colors．
☆Try using props
Birds will often land on a stick or post near a seed feeder before going to the feeder．The background was just an out of focus fence but you can use anything you want for a background, and then wait for a bird to perch.
46. The main purpose of the passage is to .
A. attract more people to photograph birds
B. call on people to set some comfort zones for birds
C. help birders learn how to identify and understand birds
D. inform birders of the results of a scientific research on birds
47．Clothes in are highly recommended when you are going bird watching．
A. red
B. brown
C. yellow
D. blue
48．are likely to be seen at 7 in the morning．

49．Which of the following statement is TRUE according to the passage?
A. A flashlight will come in handy when you look for owls．
B. It will be wise for birders to hire a guide for themselves．'
C. Birders have to bring some notebooks to keep records of birds' habits．
D. A stick in the yard may scares birds off when you are photographing them．

Everybody cheats. Whether it’s the taxi driver who tricks a visitor and takes them the long way round, or the shop assistant who doesn’t give the correct change, or the police officer who accepts a bribe (贿赂) – everybody’s at it. Cheats in the nest include the scientist whose research was based on fake data, the game show competitors who worked with a friend in the audience or win a million pounds, and the doctor who made up his qualifications and wasn’t really a doctor at all. Everybody cheats; nobody’s playing the game.
Is cheating acceptable, a natural way of surviving and being successful? Or is it something that should be frowned on, and young people discouraged from doing? If it’s the latter how can we explain to children why so many bend the rules?
Take sport for example. The Word Cup was filled with cheating. Whether diving, pretending to be hurt or denying a handball, footballers will do anything for a free – kick or a penalty shot. France striker Henry denied cheating to win the free –kick which led to his side’s second goal in their 3 –1 victory over Spain. Many footballers, however, are often putting it on. Whatever the nationality there’s one common ploy: the player rolls over holding their leg, ankle or head seeming to be in great pain. As a result a yellow card and / or free – kick is given for the foul and then, a few seconds later, the player is up and about as if nothing had happened ! The ref (裁判) may be taken in by it but youngsters watching the game aren’t. they also see their heroes getting away with it.
Of course it’s not just football. In 1998 the Tour de France, the world’s greatest cycling event, was hit by a drug – taking scandal (丑闻). The 40 bottles of forbidden drugs found with the Fustian team caused a massive investigation that almost caused the Tour to be abandoned. One rider, Veronique, was banned for 9 months. He claimed: “You have cheats in sport, just as you do in business – there will always be people trying to take a short cut. At least we’re not turning a blind eye to the problem, which other sports are.”
Is it all unavoidable? There’s huge pressure on all athletes to perform for their fans and for their sponsors. It’s success, money and power that rule professional sport rather than an honest at tempt to do the best one can.
Meanwhile companies around the world are losing billions of dollars to fake products. From cut price CDs and DVDs to sportswear, cheap fake products are everywhere. It has become socially acceptable to buy fake Gucci bags and illegal copies of films. If parents are doing this, their children will follow.
So perhaps it’s not surprising that around the world more pupils than ever are caught cheating during exams. In one case missing exam papers were put up for sale on the Internet. In another, widespread cheating took place by pupils using their mobile phones to receive tested answers. They blame the pressure put on them to do well in exams. It doesn’t help that their role models are also cheats. Surely we can’t complain when we’re setting such a bad example.
50．According to the passage, in which way can a game show player cheat?
A．By taking an indirect way. B．By gaining aid from a friend.
C．By taking forbidden drugs. D．By selling fake products.
51．The phrase “be frowned on”(Paragraph 2) most probably means .
A．to be disapproved of B．to be pushed forward
C．to be taken the place of D．to be stuck with
52．The writer’s suppose for writing this passage is to .
A．explain why people in almost every field cheat
B．complain about cheats in school education
C．persuade young people not to cheat in exams
D．blame the society for tolerating cheats
53．The writer mentions the example of the World Cup in Paragraph 3 in order to .
A．show cheating is a common phenomenon nowadays
B．discuss the relationship between sport and cheating
C．explore the nature of cheating in important events
D．warn coaches and athletes of the danger of cheating
54．Which of the following is the main idea of the passage?
A．Exams are not a good way of testing children.
B．Children are natural cheats.
C．If adults cheat, children will cheat too.
D．Everyone including children cheats.
D
When I left home for college, I sought to escape the limited world of farmers, small towns, and country life. I long for the excitement of the city, for the fast pace that rural life lacked, for adventure beyond the horizon. I dreamed of exploring the city, living within a new culture and landscape, and becoming part of the pulse of an urban jungle.
Yet some of my best times were driving home, leaving the city behind and slipping back into the valley. As city life disappeared and traffic thinned, I could see the faces of the other drivers relax. Then, around a bend in the highway, the grassland of the valley would come into being, offering a 6 of gentle rolling hills. The land seemed permanent. I felt as if I had stepped back in time.
I took comfort in the stability of the valley. Driving through small farm communities, I imagined the founding families still rooted in their grand homes, generations working the same lands, neighbors remaining neighbors for generations. I allowed familiar farmhouse landmarks to guide me.
Close to home, I often turned off the main highway and took a different, getting familiar farms again and testing my memory. Friends lived in those houses. I had eaten meals and spent time there; I had worked on some of these farms, lending a hand during a peak harvest, helping a family friend for a day or two. The houses and lands looked the same, and I could picture the gentle faces and hear familiar voices as if little had been changed. As I eased into our driveway I’d return to old ways, becoming a son once again, a child on the family farm. My feelings were honest and real. How I longed for a land where life stood still and my memories could be relived. When I left the farm for college, I could only return as visitor to the valley, a traveler looking for home.
Now the farm is once again my true home. I live in that farmhouse and work the permanent lands. My world may seem unchanged to casual observers, but they are wrong. I now this; if there’s a constant on these farms, it’s the constant of change.
The good observer will recognize the differences. A farmer replants an orchard (果园) with a new variety of peaches. Irrigation is added to block of old grapes, so I imagine they vineyard has a new owner. Occasionally the changes are clearly evident, like a FOR SALE sign. But I need to read the small print in order to make sure that a bank has taken possession of the farm. Most of the changes contain two stories. One is the physical change of the farm, the other involves the people on that land, the human story behind the change.
I’ve been back on the farm for a decade and still haven’t heard all the stories behind the changes around me. But once I add my stories to the landscape, I can call this place my home, a home that continues to evolve and changes as I add more and more of my stories.
A poet returns to they valley and says, “How closed – minded you all are.” He comments about the lack of interest in the sorts, I social and environmental issues, In the poverty and inequality of our life. “Little has changed in the valley.” He was born and raised here, so he might have the right to criticize and lecture us. Yet he speaks for many who think they know the valley. How differently would others think of us if they knew the stories of a grape
harvest in a wet year or a peach without a home?
55．The most important reason why the writer wanted to move to the city is that .
A．he did not want to work on the farm B．he wanted to make new friends
C．he was eager for a different life there D．there were more things to do there
56．What made the writer relax as he drove from the city to the country?
A．He could see for miles and miles.
B．The traffic moved more slowly.
C．The people he passed seemed to be calmer.
D．The land seemed familiar to him.
57．When driving through the valley the writer was guided home by .
A．familiar farmhouses which left him a good memory
B．houses that had sheltered generations of the same family
C．land that had been worked by a family for generations
D．large farms which stretched out right before him.
58．When he was in college, why was the writer sad when he returned to his family home?
A．He remembered how hard he used to work.
B．He realized that he was only a visitor.
C．He recognized the old housed and land.
D．He remembered his next door neighbors.
59．Which of the following most likely indicates that there is a sad human story behind a physical change on the farm?
A．A new variety of peach is being planted.
B．Irrigation is being added to a grape operation.
C．A piece of land is being sold by a bank.
D．A farm is being sold to a large corporation.
60．The fact that most upsets the writer with the poet is that .
A．the poet prefers to live in the urban area
B．the poet thinks that the folk people are backward
C．the poet says that little has changed in the valley
D．the poet’s criticism and comments are not objective
第二节：下面文章中有5处（第61~65题）需要添加小标题。请从以下选项（A、B、C、D、E和F）中选出符合各段意思的小标题，并在答题纸上将相应选项的标号涂黑。选项中有一项是多余选项。
A. Network.
B. Do things alone.
C. Become a local.
D. Join a gym or club.
E. Join a Business Group
F. Be polite to People You Meet
Moving to a new city can be both exciting and scary. Whether you are moving for a job, school or just to start over somewhere new, it can function as a fresh start. However, leaving behind old friends and finding new ones is not always easy. Maintaining a positive attitude and being open to new situations and people will make the adjustment easier.
61.________
Trying new things will always put you in the position to run into new people. However, chances are, if you are by yourself instead of with a group of friends, other people will be more comfortable approaching you because
they are less likely to feel as though they are bothering you or intruding. Go for walks by yourself, read a book in the park or have dinner at a restaurant alone. Doing things alone can also make you appear confident and interesting to others.
62.________
Visit the same coffee shops or restaurants as often as possible. Talk to the employees and be friendly. Over time, the people that work there will recognize you and you can build relationships with them that way. This can also help you feel like you blend in and belong in your new neighborhood. Ask the employees for suggestions on things to do. They are great resources to find out the latest activities and events happening in your city, and they may even join you.
63.________
You will not meet new people sitting in your house, so you will want to put yourself in situations with other people. Joining a gym, club or other social group can be a low pressure way to meet new people who have the same interests as you. Moving to a new city is a great time to try a new activity you are interested in, such as yoga or martial arts.
64.________
If you moved for a job or school, you will be surrounded by new people. Even if they are not necessarily the type of people you would normally be friends with, try to keep an open mind. Common interests provide the start of many wonderful friendships. Your coworkers or fellow students will likely be able to introduce you to other people you may get along with as well.
65.________
Sites like Linked In and Yahoo offer several online forums (论坛) that can help expand networking opportunities. You could become friends with someone through one of the online discussions and then meet in person later. Linked In lists several groups it feels you might enjoy. Get involved with the groups that meet in person with things like business book groups, networking events, or social mixers. To join a Yahoo group, click on “groups,” then “business and finance.” Type in the name of your city in the search screen, and scroll through the list of local groups that appear.

高考复习：高三生如何准备月考模拟考 未 2014-01-10 0832 高考复习：高三生如何准备月考模拟考 高三的日子，黑板上距高考倒计时的数字被放大了无数倍，生活由语数外理化生拼凑而成，铺天盖地的考试是一年的主旋律。高三的月考，尽管你心里清楚这只是高考的练兵，但走进考场，依然忐忑，依然期待通过考试来验证自己的进步。那么，充分的考前准备就是你胜利的第一重保障，我们一起来想一想，月考之前要准备些什么。 知己知彼百战不殆 《兵法》有云：“知己知彼，百战不殆。”了解月考的考试内容和考试目的是第一步。高三的四次月考，会各有侧重。首先，考试内容会配合复习进度，考查阶段学习重点和难点，其次，四次考试会以变换题型的方式对高考进行“围追堵截”，真正实现高考前预备战的补漏作用。另外，月考的难度系数可能会略高于高考，这样才能起到“带着沙包奔跑”的加码作用。 这样，我们在考前复习时，就应针对以上的内容进行。不管现在复习的内容在高考所占比例有多少，都以阶段学习为界，寻找重点，提前加强训练。前两次月考已经考过的题型可以减少训练，贴近高考却一直没有考查过的题型作为复习重点。中等难度，甚至高难度的习题应该集中练习，以避免出现考试当中措手不及的惶惶然。复习中也不要采取“题海战术”，题要做，但要有针对性地做，明确考试对象，主攻考试重点，能让你有限的复习时间“事半功倍”。在三中，一些善于思考，对高考有计划、有全局准备的同学，甚至可以推断出下次考试的某些题型和考查内容。有的放矢，才能射中靶心。 有些同学不太愿意为了月考放弃自己的高考长期计划，觉得月考没有那么重要，这种全局式的复习值得提倡，但，我要提醒你，如果你从来没有在任何一次考试中找到全力出击的感觉，到了高考，也许就失去了临场战斗力！月考给你带来的益处并不仅仅是每次考查的知识点，更重要的是你能对每场考试全力以赴的准备，超越自我的发挥。 临阵磨枪不快也光 “临时抱佛脚”是学生在学习生涯中很难避免的尴尬局面，所以“不快也光”成了我们挂在嘴边的自我安慰。其实，有时候临阵磨好了枪，还能打个胜仗呢！时间短，任务重，怎么磨才够光呢？ 最接近考试状态的就是计时做套题，这是最能模仿考试状态的做法。在做题过程中，注意合理分配做题时间，核对答案后，及时弥补自己知识上的漏

It includes airfare ($225), hotel ($170), dining out ($116) and dressing up ($95) and the gift. If you have weddings to attend this year, here are some tips for you to avoid breaking the bank. 1. Book flights in advance The moment you decide to attend a wedding is the time to check flight prices at the best time. Plane fares are higher in the summer, especially in July and August. Booking in advance will save you money, as will watch for sales on lower-cost carriers like JetBlue and Frontier. You can check Google Flights for a calendar of prices showing the cheapest days to fly from apps like Hopper to get real-time alerts when a fare is at its lowest price point. 2. Don't blow your budget on the gift If you've got the money, an expensive gift is lovely. But there's no need to take out loans to prove your love for the happy couple. Skip an expensive necklace by giving (an appropriate amount of) cash instead. To save on the gift, consider making one: A photo album or scrapbook of memories with the bride and groom shows how much you care. You could also share the gift with other guest(s) or even make gifts with DIY ideas by yourself to save money. 3. Use old dresses and suits You don't always have to be on a new dress for a wedding. While men have the option of repeating their suits, women are more likely to spend money on new clothes for the special occasion. But before you take out your wallet, consider reinventing something already in your
