Part II Reading Comprehension (Skimming and Scanning) (15 minutes)
Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions on Answer Sheet 1. For questions 1-7, choose the best answer from the four choices marked [ A ], [ B ], [ C ] and [ D]. For questions 8-10, complete the sentences with the information given in the passage.
The Earth
Power and Light
Compared to the rest of the universe, the Earth is very small. Our planet and seven others orbit the Sun, which is only one of about 200 billion stars in our galaxy. Our galaxy, the Milky Way, is part of the universe, which includes millions of other
galaxies and their stars and planets. By comparison, the Earth is microscopic.
Compared to a person, on the other hand, the Earth is enormous. It has a diameter of 7,926 miles ( 12,756 kilometers) at the equator, and it has a mass of about 6 x 1024 kilograms. The Earth orbits the Sun at a speed of about 66,638 miles per hour (29.79 kilometers per second). Don’t dwell on those numbers too long, though; to a lot of people, the Earth is inconceivably, mind-bogglingly big. And it’s just a fraction of the size of the Sun.
From our perspective on Earth, the Sun looks very small. This is because it’s about 93 million miles away from us. The Sun’s diameter at its equator is about 100 times bigger than Earth’s, and about a million Earths could fit inside the Sun. The
Sun is inconceivably, mind-bogglingly bigger.
But without the Sun, the Earth could not exist. In a sense, the Earth is a giant machine, full of moving parts and complex systems. All those systems need power, and that power comes from the Sun.
The Sun is an enormous nuclear power source--through complex reactions, it transforms hydrogen into helium, releasing light and heat. Because of these reactions, every square meter of our planet’s surface gets about 342 Watts of energy from the Sun every year. This is about 1.7 ~ 1017 Watts total, or as much as 1.7 billion large power plants could generate. You can learn about how the Sun creates energy in How the Sun Works.
When this energy reaches the Earth, it provides power for a variety of reactions, cycles and systems. It drives the circulation of the atmosphere and the oceans. It makes food for plants, which many people and animals eat. Life on Earth could not exist without the Sun, and the planet itself would not have developed without it.
To a casual observer, the Sun’s most visible contributions to life are light, heat and weather.
Night and Day
Some of the Sun’s biggest impacts on our planet are also its most obvious. As the Earth spins on its axis, parts of the planet are in the Sun while others are in the shade. In other words, the Sun appears to rise and set. The parts of the world that are in daylight get warmer while the parts that are dark gradually lose the heat they absorbed during the day.
You can get a sense of how much the Sun affects the Earth’s temperature by standing outside on a partly cloudy day.
When the Sun is behind a cloud, you feel noticeably cooler than when it isn’t. The surface of our planet absorbs this heat from the Sun and emits it the same way that pavement continues to give off heat in the summer after the Sun goes down. Our
atmosphere does the same thing-it absorbs the heat that the ground emits and sends some of it back to the Earth.
The Earth’s relationship with the Sun also creates seasons. The Earth’s axis tips a little-about 23.5 degrees. One hemisphere points toward the Sun as the other points away. The hemisphere that points toward the Sun is warmer and gets more light--it’s summer there, and in the other hemisphere it’s winter. This effect is less dramatic near the equator than at the poles, since the equator receives about the same amount of sunlight all year. The poles, on the other hand, receive no sunlight at all during their winter months, which is part of the reason why they’re frozen.
Most people are so used to the differences between night and day (or summer and winter) that they take them for granted.
But these changes in light and temperature have an enormous impact on other systems on our planet. One is the circulation of air through our atmosphere. For example:
The Sun shines brightly over the equator. The air gets very warm because the equator faces the Sun directly and because the ozone layer is thinner there.
As the air warms, it begins to rise, creating a low pressure system. The higher it rises, the more the air cools. Water condenses as the air cools, creating clouds and rainfall. The air dries out as the rain falls. The result is warm, dry air, relatively high in our atmosphere.
Because of the lower air pressure, air rushes toward the equator from the north and south. As it warms, it rises, pushing the dry air away to the north and the south.
The dry air sinks as it cools, creating high-pressure areas and deserts to the north and south of the equator.
This is just one piece of how the Sun circulates air around the world--ocean currents, weather patterns and other factors also play a part. But in general, air moves from high-pressure to low-pressure areas, much the way that high-pressure air rushes from the mouth of an inflated balloon when you let go. Heat also generally moves from the warmer equator to the cooler poles.
Imagine a warm drink sitting on your desk--the air around the drink gets warmer as the drink gets colder. This happens on Earth on an enormous scale.
The Coriolis Effect, a product of the Earth’s rotation, affects this system as well. It causes large weather systems, like hurricanes, to rotate. It helps create westward-running trade winds near the equator and eastward-running jet streams in the northem and southem hemispheres. These wind patterns move moisture and air from one place to another, creating weather patterns. (The Coriolis Effect works on a large scale--it doesn’t really affect the water draining from the sink like some people suppose. )
The Sun gets much of the credit for creating both wind and rain. When the Sun warms air in a specific location, that air rises, creating an area of low pressure. More air rushes in from surrounding areas to fill the void, creating wind. Without the Sun, there wouldn’t be wind. There also might not be breathable air at all.
Water and Fire
The Sun has a huge effect’on our water. It warms the oceans around the tropics, and its absence cools the water around the poles. Because of this, ocean currents move large amounts of warm and cold water, drastically affecting the weather and
climate around the world. The Sun also drives the water cycle, which moves about 18,757 cubic miles (495,000 cubic kilometers) of water vapor through the atmosphere every year.
If you’ve ever gotten out of a swimming pool on a hot day and realized a few minutes later that you were dry again, you have firsthand experience with evaporation. If you’ve seen water form on the side of a cold drink, you’ve seen condensation in
action. These are primary components of the water cycle, also called the hydrologic cycle, which exchanges moisture between bodies of water and land masses. The water cycle is responsible for clouds and rain as well as our supply of drinking water.

50 , a biodegradable(生物可降解的) mobile phone was introduced by scientists. It is hoped that the new type of phone will encourage 51 to recycle.
Scientists have come up with a new material over the last five years. It looks like any other 52 and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any toxic 53 . British researchers
used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it 54 nitrates (硝酸盐). These feed the seed and help the flower grow.
Engineers have designed a small 55 window to hold the seed. They have made sure it only grows when the phone is thrown away.
"We’ve only put sunflower seeds into the covers so far. But we are working with plant 56 to find out which flowers would perform best. Maybe we could put roses in next time," said one scientist.

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked [A], [ B ], [ C ] and [D ]. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.
Passage One
Questions 57 to 61 are based on the following passage.
Over the last 25 years, British society has changed a great deal--or at least many parts of it have. In some ways, however, very little has changed, particularly where attitudes are concerned. Ideas about social class--whether a person is "working-
class" or "middle-class"--are one area in which changes have been extremely slow.
In the past, the working-class tended to be paid less than middle-class people, such as teachers and doctors. As a result of this and also of the fact that workers’ jobs were generally much less secure, distinct differences in life-styles and attitudes came into existence. The typical working man would collect his wages on Friday evening and then, it was widely believed, having given his wife her "housekeeping", would go out and squander(浪费) the rest on beer and betting.
The stereotype ( 陈腔滥调) of what a middle-class man did with his money was perhaps nearer the truth. He was—and still is--inclined to take a longer-term view. Not only did he regard buying a house of these provided him and his family with
security. Only in very few cases did workers have the opportunity (or the education and training) to make such long-term plans.
Nowadays, a great deal has changed. In a large number of cases factory workers earn as much, if not more, than their middle-class supervisors. Social security and laws to improve century, have made it less necessary than before to worry about
"tomorrow". Working-class people seem slowly to be losing the feeling of inferiority they had in the past. In fact there has been a growing tendency in the past few years for the middle-classes to feel slightly ashamed(惭愧的)of their position.
The changes in both life-styles and attitudes are probably most easily seen amongst younger people. They generally tend to share very similar tastes in music and clothes, they spend their money in having a good time, and save for holidays or longer-term plans when necessary. There seems to be much less difference than in precious generations. Nevertheless, we still have a wide gap between the well-paid (whatever the type of job they may have and the low-paid. As long as this gap exists, there will always be a possibility that new conflicts and jealousies will emerge, or rather that the old conflicts will re-appear,but between different groups.

57. Which of the following is seen as the cause of class differences in the past?
[A] Life style and occupation.
[B] Attitude and income.
[C] Income and job security.
[D] Job security and hobbies.
58. The writer seems to suggest that the description of______is closer to truth.

[B] working-class ways of spending the weekend
[C] working-class drinking habits
[D] middle-class attitudes
59. According to the passage, which of the following is NOT a typical feature of the middle-class?
[A] Desiring for security.
[B] Making long term plans.
[C] Having priorities in life.
[D] Saving money.
60. Working-class people’s sense of security increased as a result of the following factor except
[A] better social security
[B] more job opportunities
[C] higher living standard
[D] better legal protection
61. Which of the following statement is incorrect?
[A] Changes are slowly taking place in all sectors of the British society.
[B] The gap between working-class and middle-class young people is narrowing.
[C] Different in income will remain but those in occupation will disappear.
[D] Middle-class people may sometimes feel inferior to working-class people.
Passage Two
Questions 62 to 66 are based on the following passage.
If a mother pushes her small son in a swing (秋千), giving only a light force each time he returns, eventually he will be swinging quite high. The child can do this for himself by using his legs to increase the motion, but both the mother’s push and the child’s leg movements must occur at the proper moment, or the extent of the swing will not increase. In physics, increasing the swing is increasing the amplitude ( 振幅 ); the length of the rope on the swing determines its natural oscillation ( 摆动 ) period. This ability of an object to move periodically or to vibrate when stimulated by a force operating in its natural period is called resonance.
Resonance is observed many times without consciously thinking about it; for example, one may find an annoying vibration or shimmy in an automobile, caused by a loose engine mount vibrating with increasing amplitude because of an out- of-round tire. The bulge ( 凸出部分) on the tire slaps the pavement with each revolution; at the natural resonance point of the engine mount, it will begin to vibrate. Such vibrations can result in considerable damage if allowed to persist. Another destructive example of resonance is the shattering of a crystal goblet by the production of a musical tone at the natural resonant point of the goblet. The energy of the sound waves causes vibration in the glass; as its amplitude increases, the motion in the glass exceeds the elasticity of the goblet, and it shatters.
An instrument called a tachometer (转速计) makes use of the principle of resonance. It consists of many tiny bars, loosely fastened together and arranged so that each bar can slide independently of the others. Movement of the bars causes changes in a dial. When placed next to a rotating motor or engine, the tachometer picks up slight vibrations which are transferred to the resonant bars. These bars begin to move, and the resulting dial may be read to find the revolutions per minute of the motor very quickly.

An adult giraffe’s head is about six feet above its heart. This means that to 67 enough blood up to the brain the circulatory 68 must be strong enough to keep the blood at very high pressure.
Biologists have known for some time that giraffes solve this problem by having 69 high blood pressure, about 70 that of human beings. But an international team of biologists began to 71 about this. If giraffes have such high blood pressure, they should have a 72 problem with swelling in their legs and feet. Why don’t giraffes
have swollen feet?
Giraffes should have 73 problem, too. Every time they bend heads __7_4__ to drink, the blood should 75 to their heads and have a hard time 76 back up (when the head is down) to the heart. How come giraffes don’t black out when they drink?
The answer to the 77 feet problem, the researchers found, is that giraffes have 78 the researchers call a "natural anti-gravity suit". It 79 out that the skin
and other 80 in their legs and feet are 81 stiffer and tougher than those of other 82 . As a result, the blood vessels in the leg cannot swell.
Therefore, the blood has nowhere to go but back to the heart. What about blood rushing to the head 83 the giraffe bends down to drink? The researchers found that the giraffe’s jugular vein, which 84 blood from the head back to the heart, has lots of one-way valves in it. In the giraffe’s neck, there are lots of muscles that flex and relax repeatedly as the animal moves its head and sucks 85 drinking water. By squeezing the valved jugular vein, they 86 blood moving back to the heart even while the animal is drinking.
