四．短文改错（10分）
This is a story told by my father: When I was boy, the most exciting thing was when to celebrate the Spring Festival. My grandma was the best cooker in th world but could make the most delicious dishes. Once, I just couldn’t wait for the Spring Festival dinner. As I was about take a piece from a cooked duck, I saw Grandma in the kitchen looking at me. Shake his head, she said, “It’s not a good time to do that, dear.” I apologize and controlled me at the best till the dinner started. You know, that was a dinner we had waited for several month.

Every day 25 million U.S. children ride school buses. The safety record for these buses is much better than for passenger cars; but nevertheless, about 10 children are killed each year riding on large school buses, and nearly four times that number are killed outside buses in the loading zones. By and large, however, the nation’s school children are transported to and from school safety.

Even though the number of school bus accidents is not large, the safety of children is always of intense public concern. While everyone wants to see children transported safely, people are divided about what needs to be done-particularly whether seat belts should be compulsory.

People in favour of seat belts on school buses-many of them parents and medical organizations-argue that seat belts are necessary not only to reduce fatality and injury, but also to teach children lessons about the importance of using them routinely in any moving vehicle. A side benefit, they point out, is that seat belts help keep children in their seats, away from the bus driver.

People who object to seat belt installation suggest that children are already well protected by the school buses that follow the Nation Highway Traffic Safety Administration’s (NHTSA) safety requirements set in 1977. They also believe that many children won’t wear seat belts anyway, and that may damage the belts or use them as weapons to hurt other children.

A new Research council report on school bus safety suggest that there are alternate safety devices and procedures that may be more effective and less expensive. For example, the study committee suggested that raising seat backs four inches may have the same safety effectiveness as seat belts.

  The report sponsored by the Department of transportation at the request of Congress, re

views seat belts extensively while taking a broader look at safety in and around school buses.

According to the passage, who has the greatest degree of control of the school buses “safety”?

A.A new Research Council.           B.The Department of Transportation.

C.The Medical Organization.         D.National Highway Traffic Safety Administration.

It may be inferred from this passage that .       .

A.many of the opponents(反对者) of seat belt installation are parents and officials of the Department of Transportation

B.proposals of seat belts on school buses would be seriously considered

C.an alternate safety device (raising seat backs four inches) may be taken into consideration

D.The Department of Transportation may either take the idea of seat belts or other measures when it reviews the whole situation

The title below which best expresses the idea of the passage is“”.

A.Making School Buses Even Safer for Children     B.Seat Belts Needed on School Buses

C.Alternate Safety Devices and Procedures         D.Safety in and around School Buses

C
RIDING in school buses in the early morning，then sitting in poorly lit classrooms，are the main reasons students have trouble getting to sleep at night，according to new research．
Teenagers，like everyone else，need bright light in the morning to allow their circadian rhythms(生理节奏)to get into step with nature's cycles of day and night．
If they don't get blue 1ight in the morning，they get to sleep an average of six minutes later at night，until their bodies are completely out of sync(同步) with the school day，researchers from Rensselaer Polytechnic Institute in New York said last month．
The finding was made by fitting goggles(护目镜)that block blue light from the sun to a group of students．The researchers discovered that their circadian rhythms were greatly affected．
Parents and teachers have been complaining in recent years that teens stay up too late at night，then fall asleep in class the next morning and do poorly in school．The new findings provide a possible explanation for the problem．
At the root of the research is the circadian rhythm, the body's natural sleep and waking cycle．Even though the Earth makes a full rotation(旋转)in 24 hours，the body's circadian cycle is about 24 hours and six minutes 1ong．The cycle is mediated(调节)by a chemical called melatonin(褪黑激素)．The body starts to produce it about two hours before it is time to sleep and, in the absence of blue 1ight，the body produces about six minutes later each day.
In the study, the researchers studied 11 students at Smith Middle School in New York, which was designed so that a lot of sunlight  reaches classrooms．
On a Friday night，the researchers measured what time the 11 students’ bodies began releasing melatonin．On Monday morning，the students were sent to school with orange goggles that blocked most blue light from their eyes to mimic(模拟) the conditions found in many---if not most--schools．
By the end of the week，the students were releasing melatonin 30 minutes 1ater in the evening---an average of six minutes a day--and going to sleep correspondingly(相应的) later．
“This is our first field study，”said lead author Mariana G．Figueiro．He said they would like to repeat it in larger studies and for longer periods of time。
If the findings are repeated，a variety of solutions are available．Ideally, new schools would be built to allow more natural sunlight into the classrooms．Students could also be exposed to more sunlight outside．
68. According to the findings related in this article, many teenagers stay up late because_______
A. they lack melatonin in their bodies
B. they have to get up so early to catch the school bus
C. their circadian rhythms are in disorder
D. they do not get enough blue light in the morning
69. According to the findings, a student who normally slept at 10:00 pm, but who spent 10 days in a poorly lit classroom, would probably be falling asleep at___________after the period.
A. 12:00pm   B. 11:30pm   C. 11:00pm   D. 10:00pm
70. What does the article tell us?
A. Unlike adults, teenagers tend to feel sleepy during daytime.
B. The sunlight is the only thing that can affect our circadian rhythms.
C. If the findings prove correct, solutions could be found to teen sleeping problems.
D. Most schools have small windows and the classrooms are poorly lit.
71. The main point of the article is to___________
A. warn teenagers not to stay up late or sleep in class
B. report on some new findings related to teenagers' sleeping problems
C. give suggestions on how to build schools
D. advertise goggles which can protect the eyes from the sun

All school buses in the northwestern provinces     with satellite positioning devices next year.

A. fitted    B. will be fitted    C. have been fitted    D. are fitted

语法填空（一）阅读下面短文，按照句子结构的语法性和上下文连贯的要求，在空格处填入一个适当的词或使用括号中词语的正确形式填空，并将答案填写在答题卷标号为46~55的相应位置上。

Cars are too expensive for many people around the world to own. Not only that, many cities are already full of traffic, and many country areas have rough roads.

So   46          do people travel those distances that are too far to walk? They use public transportation. If you ride the subway or bus   47            you live, you can appreciate some of the benefits of public transportation. With many people   48            (share) one bus or train, there is less traffic and, more   49              （importance）, less pollution.

Which of the types of mass transit   50           (describe) below are you familiar with? If a regular bus can hold       dozens of people, imagine what a bus        51             (two) the size can hold! In Great Britain, there are many buses that are known as double-deckers (cars with two floors).

Buses in Haiti are often very crowded. It’s not   52            (common)         for passengers to actually sit on the rooftops. Buses are sometimes called “tap-taps”, because the   53             (ride) on the roof tap（敲击）when they want to be dropped off.

Many large cities around the world take advantage of the space beneath the streets and run underground trains. People in Paris, Mexico City and Tokyo may use the subway system to get to school, to work, or to visit friends in other             54         (neighbor). Both the Japanese and French have developed        High-speed trains to link various cities. While electric trains in North America average 130 kph, the French TGV ( high-speed-train ) is the world’s fastest,         55               (average) over 270 kph!
