Welcome to your future life!
You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people your age could live to be 150, so at 40, you’re not old at all. And your parents just had an anti-aging(抗衰老的) treatment. Now, all three of you look the same age !
You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change your clothes’ color or pattern.
You walk into the kitchen. You pick up the milk, but a voice sa ys, “You shouldn’t drink that!” Your fridge has read the chip (芯片) that contains information about the milk , and it knows the milk is old . In 2035, every article of food in the grocery store has such a chip.
It’s time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve(袖子). Such “smart technology” is all around you.
So will all these things come true? “For new technology to succeed,” says scientist Andrew Zol li , “it has to be so much better that it replaces what we have already.” The Internet is one example --what will be the next?

Why do people drink too much, ea t too much, smoke cigarettes or take drugs? What’s to blame for all the bad behavior? Most people would say that, while these self-destructive (自我毁灭的) acts can have many root causes, they all have one obvious thing in common: they are all examples of failures of self-control, lacking the will power to resist（抵抗）them.
According to a recent study, however, if you really think about it, something about that simple answer doesn’t quite make sense. In fact, it turns out that sometimes it’s having will power that really gets you into trouble.
Think back to the time you took your very first sip of beer. Disgusting, wasn’t it? When my father gave me my first taste of beer as a teenager, I wondered why anyone would voluntarily drink it. And smoking? No one enjoys their first cigarette —it tastes awful. So even though smoking, and drinking alcohol or coffee, can become temptation (诱惑) you need will power to resist, they never, ever start out that way.
Just getting past those first horrible experiences actually requires a lot of self-control. Ironically (讽刺的是), only those who can control themselves well, rather than give in to them, can ever come to someday develop a “taste” for Budweiser beer, Marlboro cigarettes, or dark-roasted Starbucks coffee. We do it for social acceptance. We force ourselves to consume alcohol, cigarettes, coffee and even illegal drugs, in order to seem experienced, grown-up, and cool.
These bad habits aren’t self-control failures — far from it. They are voluntary choices, and they are in fact self-control successes. Self-control is simply a tool to be put to some use, helpful or harmful. To live happy and productive lives, we need to develop not only our self-control, but also the wisdom to make good decisions about when and where to apply it.
28. What do most people think causes bad behavior?
A. Being forced by others.
B. Not having enough will power.
C. Enjoying their first experiences.
D. Following the examples of their friends.
29. The author mentions his experience in the third paragraph to prove ____.
A. will power helps develop bad habits sometimes
B. drinking beer is harmful to the health of teenagers
C. self-control should be developed when one is young
D. everyone can be challenged by different temptations
30. In the last paragraph, the author stresses that ____.
A. without self-control, no one can succeed
B. bad habits don’t always lead to bad results
C. applying self-control correctly is important
D. people can develop wisdom from bad behavior
31. What would be the best title for the passage?
A. My First Sip of Beer
B. Do You Have Will Power ?
C. Will Power Benefits Us
D. Dark Side of Self-control
D
Imagine your body is like the house you live in. Every day, your family creates rubbish. The rubbish builds up until it is put out for the weekly garbage collection.
Now, say you put three bags of garbage out, but because one of the collectors was away sick, only two bags are collected. You take the leftover bag inside to be put out again next week. The following week you put on another three bags, plus the leftover bag from last week. But again, only two bags are collected. Imagine this cycle is repeated over the following weeks.
This is a simple description of what happens to your body when your kidneys (肾脏) don’t work efficiently. Your body is not thoroughly emptied of waste products. Other areas of the body such as blood pressure and red blood cell production are affected and the insidious process that may lead to kidney failure begins.
It’s not uncommon for people to lose up to 90% of their kidney function before developing any symptoms. There may be no warning signs. This makes early detection (诊查) difficult.
Kidney’s main job is to remo ve toxins (毒素) and unwanted water from our blood. Every day our kidneys clean an average of 200 litres of blood. Kidney failure may be a gradual and silent process, going unnoticed because there is no apparent pain.
Research shows that more than 25% of the patients requiring dialysis (透析) do not see a kidney specialist before they have to do so. Some risk factors for kidney disease such as age and genetic make up are out of our control; however, some changes in lifestyle may help prevent
kidney damage．Two major risk factors for kidney disease, diabetes (糖尿病) and high blood pressure, have been on the rise over the last few decades．Both conditions are chiefly affected by being overweight and not getting enough exercises, which are the potential risk factors for the kidney disease.
32. The author gives the example of the house we live in to indicate that _______.
A. it’s safe and harmless for our body to keep some waste
B. it’s important for our body to empty the waste in time every day
C. our body will not produce any waste if our kidneys work efficiently
D. it doesn’t matter much if the waste in our body is not emptied in time
33. The underlined word “insidious” in the third paragraph means _______.
A. smooth and safe
B. obvious and fast
C. gradual and unnoticed
D. long and painful
34. We can infer that when we find some symptoms related to our kidneys, _______.
A. the kidney failure begins
B. the kidneys can still work properly
C. we have lost about 10% of kidney function
D. the kidneys may have been seriously damaged
35. Which of the following helps prevent kidney damage most effectively?
A. Go to see a kidney specialist shortly before dialysis starts.
B. Take enough exercise and make early detection of kidney disease.
C. Try to keep low blood pressure and a stable lifestyle.
D. Go to hospital whenever you find any warning signs.
第二节：根据短文内容, 从短文后的选项中选出能填入空白处的最佳选项.选项中有两项为多余选项. （共5小题；每小题2分，满分10分）
If you find that your teacher is unfair to you, think about what is happening. Try to find out whether your teacher really dislikes you, or whether something else is going on. Here are some questions to ask yourself:
36 Ask your classmates if they are having trouble with the teacher, too. If they say yes, perhaps your teacher is to blame.
Are you working up to your ability? Maybe you got a C in your last test, and your teacher
told you that you could do better. And the kid sitting beside you got a C, too. 37 Isn’t this unfair? Well, it could be that your teacher knows that you could do better if you put more effort into it. 38 .
39 There’s nothing wrong with being sensitive (敏感的) ，but if you react to criticism quite differently from others, this coul d be a reason why you think your teacher doesn’t like you.
Does your teacher seem to act unfairly all the time, or just once in a while? Think about the harsh (苛刻的) things your teacher has done to you. Are these things happening every day, or just once or twice a month? If your teacher really hates you, you would probably be picked on all the time. 40 .
A. Are you the only person being treated badly, or is your teacher rough on the whole class?
B. Are you getting along well with your classmates?
C. Are you more sensitive than other students?
D. Are you interested in your lessons?
E. If your teacher has acted unfairly only a few times, then there’s probably something else going
on.
F. Teachers often grade students by different standards.
G. But the t eacher didn’t say anything to him！

Dear editor，
I am Li Ming, a Senior three student in Jinghua Middle School. I am writing to tell you about some symptoms of anxiety among us students before exams．
Most of us feel nervous whenever we are taking an important exam. Some will feel dizzy or tired, some will suffer from lack of sleep, and some will lose their appetite. (In fact, all these
symptoms have terrible effects on our exams and) we are all eager to get rid of them．
First of all，we should study hard every day and make careful plans for every exam. In this way
we can avoid suffering from the pressure of exams. Second, enough sleep can make us energetic
and enable us to perform well in an exam. Therefore，during the period of exams，we should not
stay up too late. We can also try a warm bath or a cup of warm milk before going to bed. They
might help us to have a sound sleep. (In my opinion, it is important for us to have a right attitude
towards exams. They are only a means of checking how we are getting along with our studies, so
there is no need to worry too much about the results. ) Besides, we’d better go out for a walk or
take some outdoor exercise before and after an exam so that we can keep ourselves relaxed (and
then concentrate ourselves on exams. )
Y ours sincerely,
i Ming

My name is Li Hua, a student from XinShiJi Senior High School. With graduation drawing near, I’m desperate for the opport unity to go to Hongkong University. Therefore, I’m writing to consult you about some necessary information. To begin with, obsessed with Environmental Science, I wonder what I’m supposed to do if I want to study the relevant majors. Besides, as many courses are taught in English in Hong Kong, is it necessary for me to take some English tests? Furthermore, I wonder if it is possible for you to tell me something about accommodation. For example, where will I live in Hong Kong, on campus or outside? Finally, could you provide me with more det ails about the living costs, the fees as well as the scholarships? Thank you for your time and attention. I’m looking forward to your early reply. 2017-2018学年宁夏石嘴山三中高二（下）期中数学试卷 （理科）(J) 副标题 一、选择题（本大题共12小题，共12.0分） 1.某人有3个电子邮箱，他要发5封不同的电子邮件，则不同的发送方法有 A. 8种 B. 15种 C. 种 D. 种 【答案】C 【解析】解：每个邮件选择发的方式有3种不同的情况， 要发5个电子邮件，发送的方法的种数有种， 故选：C． 每个邮件选择发的方式有3种不同的情况，利用乘法原理，可得要发5个电子邮件，发送的方法的种数． 本题考查乘法原理的运用，考查学生的计算能力，比较基础． 2.若直线的参数方程为为参数，则直线的斜率为 A.
