阅读下面短文,用英语回答文后所给的5个问题。
Bacteria(细菌) are extremely small living things. While we measure our own sizes in inches or centimeters, bacterial size is measured in micron. One micron is a thousandth of a millimeter; a pinhead is about a millimeter across. Rod-shaped bacteria are usually from two to four microns long, while rounded ones are generally one micron across. Thus, if you magnified a rounded bacterium a thousand times, it would be just the size of a pinhead, while a grown-up human enlarged by the same amount would be over a mile tall.
Even with an ordinary microscope(显微镜), you must look closely to see bacteria. Using a magnification of 100 times, one can hardly find bacteria. Nor can one make out anything of their structure(结构), of course. Only by using special colors, can one see that some bacteria have wavy-looking “hairs” called flagella. Others have only one flagellum. The flagella move round a central point, pushing the bacteria through the water. Many bacteria lack flagella and cannot move about by their own power, while others can move along over surface by some little-understood “machinery”.
From the bacterial point of view, the world is a very different place from what it is to humans. To a bacterium, water is as thick as molasses(糖浆) is to us. Bacteria are so small that they are affected by the movements of the chemical molecules(分子) around them. Bacteria under microscopes, even those with no flagella, often jump up and down in the water. This is because they knock with the water molecules and are pushed this way and that.
47. What does the underlined word “magnified” mean?
________________________________________________________________
48. What is the smallest according to the passage?
________________________________________________________________
49. What is the relationship between a bacterium and its flagella is most nearly like?

答案

47. The underlined word magnified means enlarged.
48. A rounded bacterium is the smallest according to the passage.
49. A boat powered by a motor.

“Sure，if they were the same age”
They weren’t even half-finished when Margle’s mother called．“Margfa! School!”
Margie went into the school next to her bedroom，and the electric teacher was waiting far her them．It was the same way every day except Saturday and Sunday
The monitor lit up，and it said，“Please put yesterday’s homework in the proper hole”
Margie sighed and threw a dirty sock at the machine．She was thinking about the old days．All the kids from the whole neighborhood came to the school，Iaughing and shouting in the yard．They could even help one another with the homework

阅读下面的短文，并根据短文后的要求答题（请注意问题后的字数要求）。
An American friend of mine who was high up in a big corporation had worked out a way of handling a flood of e-mails before most of us had even heard of the concept. If any information he was sent was vital enough, his lack of response could ensure the sender rang him up. If the sender wasn’t important enough to have his private number, the communication couldn’t be that important. My friend is now even more senior in the same company, so the strategy must work.
Almost every week now, there seems to be a report suggesting that we are all being driven crazy by the bother of e-mail. If this is the case, it’s only because we haven’t developed an appropriate discrimination in dealing with it.
______. Firstly, you junk anything with an exclamation mark or a string of capital letters, or from any address you don’t recognize or feel confident about.
Secondly, e-mails don’t all have to be answered. Because e-mailing is so easy, there’s a tendency for correspondence to carry on for ever, but it is permissible to stop an endless discussion or to accept a point of information sent by a colleague without acknowledging it.
Thirdly, a reply e-mail doesn’t have to be the same length as the original. We all have e-mail pals who send long, chatty e-mails, which are nice to receive, but who then expect an equally long reply. The charm of e-mail can consist in the simple, incomplete sentence, totally regardless of the format of the letter sent by post. You are perfectly within the bounds of politeness in responding to a marathon e-mail with a brief reply.
76. Which sentence in the passage it the closed in meaning to the following one?
The possible existence of annoyance results from our inability to sort out e-mails.
_______________________________________________________________
_______________________________________________________________
77. Fill in the blank in Paragraph 3 with a proper sentence. (within 10 words)
____________________________________________________________
78. What advice is given in the last paragraph? (within 10 words)
_______________________________________________________
79. For what purpose does the author mention his American friend in Paragraph 1?
(within 10 words)
_____________________________________________________________
80. Translate the underlined sentence in the last paragraph into Chinese.

简答题（共3小题；每小题1.5分，满分4.5分）
Tsunamis (海啸) are a series of huge waves created by an underground movement such as an earthquake or a volcanic eruption (火山喷发) . A tsunami can travel hundreds of miles per hour in the open ocean and hit the land with huge waves.
From the area where the tsunamis come, waves travel in all directions. Once the waves approach the coast, the

y will become more than 100 feet in height. The topography (地形) of the coastline and the ocean floor will influence the size of the wave. There may be more than one wave and the latter one may be larger than the one before. That is why a small tsunami at one beach can be a huge wave a few miles away.
All tsunamis are dangerous, even if they may not damage every coastline they strike. A tsunami can strike anywhere along most of the US coastline. Many harmful tsunamis have occurred along the coasts of California, Oregon, Washington, Alaska and Hawaii.
A movement of the ocean floor, caused by earthquakes, most often causes tsunamis. If a tsunami occurs close to a coast, the first wave could reach the beach in a few minutes, even before a warning is given. Areas are at greater risk if they are less than 25 feet above sea level and within a mile of the coastline. Drowning is the most common cause of death during a tsunami. Tsunami waves are very harmful to buildings. Other dangers include floods, pollution of drinking water, and fires from gas lines.
An accurate prediction (预报) system will allow authorities (官方) to issue timely warnings and save lives in the event of a shore-bound tsunami. But forecasting tsunamis accurately is very difficult because the ocean is usually calm before they strike land.
65. What can cause tsunamis according to the passage? ( 回答词数不超过6个 )
66. What harm can a tsunami bring besides killing people and damaging buildings? ( 回答词数不超过15个 )
67. Why is it very difficult to forecast tsunami accurately ? ( 回答词数不超过9个 )

According to a new study, preschool boys perform better on tests that measure learning and other important skills when they are in classes that have more girls than boys. This doesn’t seem to apply to girls, though. For preschool girls, the presence or absence of boys does not affect learning.
“The study raises questions about having all-boy or all-girl classes for preschool”, says psychologist Arlen Moller, who led the study. She added, “Previous researches have shown that high-school girls may study better in all-g irl schools. In middle school, however, the effects of same-sex schooling

are unclear, and even less is known for very young kids.” To find out, researchers studied 70 preschool classes with a total of 806 children who were between 3.5 and 6 years old. For each class, teachers recorded the student’s progress over a 6.5-month school year.
Their data included scores of motor skills, social skills and thinking skills. Researchers found that boys developed each of these skills more quickly when there were more girls in the class than boys.
In majority-girl classrooms, boys developed at the same rate as girls. But in classes where boys were the majority, boys developed more slowly than girls. Girls tended to advance in classrooms which had any combination of boys and girls.
The study is one of the first to look at how the proportion of boys and girls in a class affects learning. Because it’s a new finding, researchers don’t know why this difference exists.
“This is an exciting topic, but it’s too early to draw any conclusion because this area is so under-explored,” says psychologist Lean Malofeeva of the High/Scope Educational Research Foundation in Ypsilanti, Michigan.
81．What is the finding of the researchers led by Arlen Moller? (no more than 15 words)(2 marks)

82．According to the research , what effect does a minority-girl class have on boy’s study?(no more than 8 words)(3 marks)

83．How does Lean Malofeeva find the study of the researchers led by Arlen Moller?(no more than 6 words)(3 marks)

84．List three abilities the researchers focused on. (on more than 7 words)(3 marks)
