There are two ways of driving in the world: if the driver’s seat is on the left and cars travel on the right side of the road, it is called “left-hand driving”, as it is in China, wh ile the other way of driving is called “right-hand driving”, as it is in Britain. Nowadays, around 65% of the world’s population drives on the right of the road, while the rest is used to driving on the left.
Though no one knows the exact reasons, it seems likely that people in ancient times travelled on the left. Roman coins show pictures of horsemen passing on each other’s right. And right-hand people generally got on a horse from the animal’s left. Obviously, it’s safer to do this at the left side of the road, and it makes sense for the horse to be ridden on the left.
A change happened in the late 1700s. When Napoleon conquered(攻占) nations, he forced them to travel on the right side of the road, which spread left-hand driving throughout Europe. However, Britain still stuck with the right-hand driving rule and countries which were part of the British Empire(帝国) were made to follow. This is why India, Australia and the former British colonies(殖民地) in Africa continue to drive on the left. One exception is Egypt, as that country was defeated(打败) by Napoleon before becoming part of the British Empire.
Some countries changed sides’until modern times. Sweden only moved to driving on the right in 1967 and Iceland changed the following year. Ghana changed sides’in 1974. On September 7, 2009, Samoa became the third country ever to change from left-to-right-hand driving for the reason that it made it easier to import (进口) cheap cars from right-hand driving Japan, Australia and New Zealand. 中/华-资*源%库
So if you want to travel to another country or go on business, make sure you know whether it is left-or right-hand driving to avoid unnecessary troubles.
24. Which picture shows the correct driving in Britain?
A B C D
25. In ancient times, Romans ___________.
A. travelled on the right
B. rode past each other’s right
C. got on the horses from the right
D. behaved as they liked
26. In modern times, countries follow the same driving way except __________.
A. Egypt.
B. China
C. Sweden
D. Australia
27. What is the writer’s purpose for writing this passage?
A. To introduce the development of the two ways of driving.
B. To compare the differences of the two ways of driving.
C. To explain the advantages of the two ways of driving.
D. To complain about the change of the two ways of driving.
C
The Bermuda Triangle is an area in the western part of the North Atlantic Ocean, near Florida in the USA, where a number of aircraft and ships are said to have disappeared mysteriously.中/华-资*源%库
①The earliest suggestion of unusual disappearances in the Bermuda area appeared in a September 17, 1950 article. Two years later, Fatemagazine published “Sea Mystery at Our Back Door”, covering the loss of several planes and ships, including the loss of Flight 19. Flight 19 alone would be covered again in the April 1962 issue of American Legion magazine. In it, author Allan W. Eckert wrote that the flight leader had been heard saying, “We are entering white water. Nothing seems right. We don’t know where we are.” In the February 1964, the article “The Deadly Bermuda Triangle”argued that Flight 19 and other disappearances were just part of strange events in the area.
②Triangle writers have used a number of supernatural ideas to explain the events. One explanation refers to leftover technology from the mysterious lost continent of Atlantis. Some of the Triangle writers related the events to UFOs. This idea was used by Steven Spielberg for his science fiction film Close Encounters of the Third Kind, in which the lost Flight 19 aircrews were taken by aliens.
③But there are also some explanation relating to nature. One of them for some of the disappearances has focused on large fields of a type of natural gas on the continental shelves. Laboratory experiments carried out in Australia have proven that bubbles can sink a large ship by decreasing the density(密度) of the water; any remains rising to the
surface would quickly disappear due to the Gulf Stream. It has been assumed that the eruption of volcanoes(火山)may produce large areas of bubbles so that water is no longer able to provide enough supporting power for ships. If this were the case, such an area forming around a ship could cause it to sink very rapidly and without any warning.中/华-资*源%库
④Violent weather is likely to be another reason. Powerful storms forming in tropical(热带的)waters have cuased thousands of deaths and caused billions of dollars in damage. These storms have in the past caused
a number of incidents related to the Triangle.
28. According to the passage, the loss of Flight 19 was first covered .
A. in 1950
B. in 1952
C. in 1962
D. in 1964
29. The sentence “Persons accepting the Bermuda Triangle as a ‘Death Triangle’ have offered a number of ways to explain it.” should be put in .
A. ①
B. ②
C. ③
D. ④
30. According to paragraph 4, the direct reason for the disappearance of ships is .
A. a type of natural gas
B. large areas of bubbles
C. the eruption of volcanoes
D. the decrease of water density
31. What is the passage mainly about?
A. The truth behind the disappearance in the Bermuda Triangle.
B. The puzzle of the Bermuda Triangle and its explanations.
C. Strange accidents that happened in the Bermuda Triangle.
D. The exploration of the Bermuda Triangle in history.
D
When times get tough, we all look for ways to cut back. When we’re hungry, we eat at home instead of going out. We take buses instead of taxis.
And we wear our old designer jeans just a few months longer. With college expenses at all-time highs, high school students are eager to do anything to cut the cost of a university education.中/华-资*源%库One cost-cutting proposal is to allow college students to get a bachelor’s degree in three years instead of four. Educational institutions have been actively exploring ways to make the learning process more efficient. But there’s a question: Would the qua lity of undergraduate education suffer Few US universities have formally approved a “three-year degree” model.
I doubt that mainstream North American colleges will carry out a three-year curriculum any time soon. For one thing, most universities already allow highly qualified students to graduate early by testing out of certain classes and obtaining a number of college credits. In addition, at famous universities, the committee who determine which courses are required and which courses are electives are unlikely to suddenly “throw out”one quarter of the required credits. Professors will resist “diluting(稀释)” the quality of the education they offer.
In my opinion, a quality four-year education is always superior to a quality three-year education. A college education requires sufficient time for a student to become skilled in their major and do coursework in fields outside their major. It is not a good idea to water down education, any more than it’ s not a good idea to water down medicine. If we want
to help students find their way through university, we should help them understand early on what knowledge and skills they need to have upon graduation. We should allow students to test out of as many courses as possible. We should give them a chance to earn money as interns(实习生)in meaningful part-time jobs that relate to their university studies, such as the five-year co-op program at Northeastern University.
32. Which of the following can be the best title?
A. It' s time to shorten the laming process
B. Best learning takes place over time
C. University education should be watered down
D. College education calls for reform
33. In most US universities, .
A. college students are offered the co - op program
B. electives' credits make up one quarter of the required credits
C. all students are required to finish four - year education before graduation
D. some excellent students can graduate ahead of time
34. We can infer that .
A. the author is a college professor
B. the author considers the university education quality very important
C. the author thinks the cost of a university education is too high for people to afford
D. the author pays special attention to the all - round development of college students
35. The first paragraph serves as a（n） .
A. explanation
B. definition
C. comment
D. introduction

Ways to Save Time
We all wish we had just a bit more time. Just think what you could
do with an extra hour or two each day: you could finally stick to an exercise routine, or spring-clean the house, or write your novel, or learn the guitar and so on. 1 But I can help you find more hours in your day for the things that really matter.
1. Get Out of Bed Earlier
If you normally get up at 7: 30 a. m. , try getting up at 7: 00 a. m. That half-hour might not sound like much, but it could be time that you use to exercise, to read that book you’ve been meaning to finish.
2
2. Do the Important Tasks First
Once you get to work, get the important ones done first(not the easy ones, or even the urgent ones). You can afford to spend at least an hour working on big, important tasks rather than on all those little urgent ones. 3 The urgent tasks will still get done, and you won’t miss the important ones.
3. Reduce Interruptions
If colleagues have a habit of hanging around your desk to chat, or
if the phone is constantly ringing, you might find that it takes you half the day to finish a simple task like writing a letter. Constant interruptions don’t just eat up time, they also break your concentration.
When you’ve got a big task to focus on, let your calls go to voicemail.
4 Wearing headphones makes it less likely that people will try to strike up a conversation.
4. 5
A few minutes chatting, browsing the web, and so on, can easily turn into hours of wasted time over the course of a day. When you’re working, work. If your concentration is slipping, take a proper break: go and get
a glass of water, or stretch your legs a bit. And if you’re facing a difficult task, try breaking it into small steps or stage s so that it’s easier to deal with.
A. Stay Focused on Your Work
B. Take Breaks When Necessary
C. If you have an office door, close it.
D. If you work like this, you’ll usually save time.
E. Would you want me to make your day longer?
F. I can’t magically m ake all your days 25 hours long.
G. Or simply to get your day off to a calm and organized start.
