第4部分：閱讀理解(第31-45題，每題3分，共45分)
下面有3篇短文，每篇短文后有5道題。請根據短文內容，為每題確定1個最佳選項。
第一篇 The Hyper-X
The Hyper-X(超音速飛機)recently broke the record for air-breathing jet planes when it traveled at a Hypersonic speed(超音速)of seven times the speed of sound.Thats about 5,000 miles per hour.At this speed，youd get around the world-flying along the equator (赤道)-in less than 5 hours.
The Hyper-X is an unmanned，experimental aircraft just 12 feet long.It achieves hypersonic speed using a special sort of engine known as a scramjet(超音速沖壓式噴氣發動機).
For an engine to burn fuel and produce energy，it needs oxygen.A jet engine，like those on passenger airplanes，gets oxygen from the air.A rocket engine typically goes faster but has to carry its own supply of oxygen.A scramjet engine goes as fast as a rocket，but it doesnt have to carry its own oxygen supply.
A scramjets special design allows it to obtain oxygen from the air that flows through the engine.And it does so without letting the fast-moving air put out the combustion(燃燒) flames.However，a scramjet engine works properly only at speeds greater than five times the speed of sound.
A booster rocket(助推火箭)carried the Hyper-X to an altitude of about l00，000 feet for its test flight.The aircrafts record-beating flight lasted just 11 seconds;That brief journey on March 27 makes a major milestone on the way to a new breed of very fast airplanes, says Werner J.A.Dahm of the University of Michigan in Ann Arbor.In the future，engineers Predict，airplanes equipped with scramjet engines could transport cargo quickly and cheaply to the brink(邊緣)of space.Such hypersonic jets could carry passengers anywhere in the world in just a few hours.
Out of the three experimental Hyper.X aircrafts built for NASA, only one is now left.The agency has plans for another 11-second hypersonic flight, this time at 10 times the speed of sound.
31 The Hyper-X broke the record because
A it was the first air-breathing jet plane.
B it flew along the equator.
C it traveled at the speed of sound.
D it reached a speed of about 5, 000 miles per hour，
32 What kind of engine did the Hyper-X use?
A A jet engine that carries its own oxygen supply.
B A jet engine that uses no oxygen.
C A scramjet engine that doesnt carry its own oxygen supply.
D A rocket engine that carries its own oxygen supply.
33 Which of the following is NOT true of the scramjet engine?
A It has been used on passenger planes.
B The air it breathes does not put out the combustion flames.
C It works at speeds greater than five times the speed of sound.
D It goes as fast as a rocket.
34 What does Werner J.A.Dahm say about the Hyper-X test flight?
A It was unsuccessful because it lasted only 11 seconds.
B It is a very important event in developing very fast airplanes.
C，It allows people to fly at an altitude of 100,000 feet.
D It can transport cargo quickly and cheaply to outer space.
35 What does NASA plan to do?
A To build one more Hyper-X aircraft.
B To carry out three more Hyper-X experiments.
C To make the aircraft fly higher and longer.
D To test another hypersonic flight at 10 times the speed of sound.
第二篇 Stop Eating Too Much
Clean your plate! and Be a member of the clean-plate club! just about every kid in the US has heard this from a parent or grandparent.Often, its accompanied by an appeal： Just think about those starving orphans(孤兒)in Africa! Sure，we should be grateful for every bite of food.Unfortunately, many people in the US take too many bites.Instead of staying clean the plate, perhaps we should save some food for tomorrow.
According to news reports, US restaurants are partly to blame for the growing bellies(肚子).A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government，according to a USA Today story.Americans traditionally associate quantity with value and most restaurants try to give them that.They prefer to have customers complain about too much food rather than too little.
Barbara Rolls，a nutrition(營養)professor at Pennsylvania State University，told USA Today that restaurant portion sizes began to grow in the l970s, the same time that the American waistline(腰圍)began to expand.
Health experts have tried to get many restaurants to serve smaller portions.Now，apparently，some customers are calling for this too.The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believed restaurants served portions that were too large;23 percent had no opinion;20 percent disagreed.But a closer look at the survey indicates that many Americans who cant afford fine dining still prefer large portions.Seventy percent of those earning at least $150，000 per year prefer smaller portions;but only 45 percent of those earning less than $25，000 want smaller.
Its not that working class Americans dont want to eat healthy.Its just that, after long hours at low-paying jobs，getting less on their plate hardly seems like a good deal.They live from paycheck(薪金支票)to paycheck, happy to save a little money for next years Christmas presents.
36 Parents in the United States tend to ask their children
A to save food for tomorrow.
B to wash the dishes.
C not to waste food.
D not to eat too much.
37 Why do American restaurants serve large portions?
A Because Americans associate quantity with value.
B Because Americans have big bellies.
C Because Americans are good eaters.
D Because Americans are too weak.
38 What happened in the 1970s?
A The US government called on its people to reduce their weight.
B Health experts persuaded restaurants to serve smaller portions.
C The United States produced more grain than needed.
D The American waistline started to expand.
39 What does the survey indicate?
A Many low-income Americans want large portions.
B Twenty percent of Americans want smaller portions.
C Fifty-seven percent of Americans want large portions.
D Forty-five percent of Americans want smaller portions.
40 Which of the following is NOT true of working class Americans?
A They work long hours.
B They live from paycheck to paycheck.
C They dont want to be healthy eaters.
D They want to save money for presents.
第三篇 Sunspots
Its not surprising that sunspots(太陽黑子)were observed by ancient astronomers(天文學家).The largest sunspots on the sun can be seen without a telescope.1t was not until the invention of the telescope(望遠鏡)in the early l7th century，however，that systematic studies of sunspots could be undertaken.The great astronomer Galileo was among the first to make telescopic observations of sunspots.
Sunspots are regions of extremely strong magnetic fields(磁場)found on the suns surface.A sunspot has a dark central core known as the umbra.The umbra is surrounded by a dark ring called the penumbra.where the magnetic field spreads outward.Sunspots appear dark because they are giving off less radiation.They are cooler than the rest of the suns surface.
Sunspots are frequently observed in pairs or in paired groups.The members of a spot pair are identified as the leading spot and the following spot.They are identified by their position In the pair In terms of the direction in which the sun rotates(旋轉).
The number of sunspots at any one time varies.A large spot group may consist of as many as 10 groups and 300 spots across the sun.The number of spots changes in a fairly regular pattern called the sunspot cycle.The largest number occurs about every 11 years.At sunspot minimum, there are at most just a few small spots.
The average lifetime of an individual spot group is roughly one solar rotation.which is about 25 days.The most persistent large spots, however, can survive for two to three months.
41 Careful observations and systematic studies of sunspots
A were made by ancient astronomers.
B started in the early 17th century.
C were made by Galileo only.
D could be made without a telescope.
42 Sunspots are cooler than the rest of the sun s surface because
A they produce less energy.
B they are buried in the sun.
C they are far away from magnetic fields.
D they are close to magnetic fields.
43 The leading spot and the following spot are the names of
A two large sunspots.
B a large spot and a small spot.
C the two spots in a spot pair.
D the central core and the ring around it.
44 If an intense sunspot activity had occurred in 1857, the next one would have been in
A 1858.
B 1862.
C 1865.
D 1868.
45 In the last paragraph the word persistent means
A important.
B effective.
C enduring.
D visible.
