阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。
Spiders are actually useful. They do not harm plants, as some people think. Instead, they protect plants by controlling insects. If you see spiders in a garden, it doesn’t mean the garden is unhealthy. It means the spiders are helping the garden stay healthy.
If you spend some time watching spiders, you may be surprised by what you see. There are many wonderful webs. They may perform skillfully on their thin silk threads. However, some spiders spin (织) no webs at all. They follow insects on the ground with all the skill and cruelty of a tiger hunting big game.
Scientists have named about 30,000 species of spiders, but they think this is only one-fourth of all the different kinds of spiders in the world. In most species, people can easily tell the female spider from the male because the female is much bigger. For example, the female black widow (黑寡妇) weighs about one hundred times as much as the male.
Female spiders lay eggs. After hatching (孵), most spiders live less than a full year, but some don’t. Tarantulas (狼蛛) do not become adults until they are 10 or 11 years old. Female tarantulas often live an extra 10 years! The baby spiders that hatch from the eggs are called spiderlings.
56. The underlined in Paragraph 2 part “a tiger hunting big game” refers to “______.”
A. laying eggs B. hatching baby spiders
C. spinning webs D. catching insects
57. How many kinds of spiders are there in the world according to the passage?
A. About 30, 000. B. About 60, 000. C. About 90, 000. D. About 120, 000.
58. What can we know from the passage?
A. If there are spiders in your garden, it means it is unhealthy.
B. All spiders can spin webs.
C. Normally, a male spider is smaller than a female one.
D. All spiders can live 10 or 11 years after hatching.
59. What will be probably talked about after the last paragraph?
A. The way spiders spin webs. B. Something about spiderlings.
C. How the spiders protect plants. D. The way spiders stay healthy.

A low-carbon lifestyle means cutting carbon dioxide emissions and living a life characterized by low-energy use, low consumption and low spending. This way of living is being accepted by a growing number of average people in China.
Before low-carbon became a popular word here, some environmentally conscious people known as "Lohas" had already devoted themselves to living green, low-carbon lifestyles. Lohas is for "lifestyles of health and sustainability." It was first introduced in 1998 by American sociologist Paul Ray and later became a popular lifestyle in western countries. After this concept was introduced into China a few years ago, Lohas was translated into a proper Chinese word "lehuo," meaning happy living.
Zhang Tao from a joint venture in Beijing is a Lohas supporter and follower. He and some others set up a Lohas club two years ago. They often get together to share their experiences about living green lifestyles or to volunteer for environmental protection activities.
Zhang says Lohas is both a lifestyle and an attitude towards life rather than just a fashion or slogan.
"A Lohas lifestyle means a natural and healthy life with low costs. We don"t drive cars, and we try our best to save water and electricity. Some people misunderstand us as being too stingy. But in fact, most of us are well-paid. We don"t do it to save money, but for the sake of the environment. Living a rich life doesn"t mean you can waste resources. We hope what we do can help save energy and reduce the pressures on earth. I know our personal strength is too small, but the changes will be great if everyone can make a little contribution."
64. A low-carbon lifestyle has the following features except_______.
A. low energy B. low wages C. low consumption D. low spending
65. A Lohas is most likely to_______.
A. drive a car to work every day B. save money to live a better life
C. turn off the tap when not using D. leave the light on day and night
66. What does the word “stingy” mean in the last paragraph?
A. generous B. mean C. rich D. willing
67. In Zhangtao’s opinion, _________.
A. Lohas is just a fashion or form B. one shouldn’t get well paid
C. one should live a happy life D. environment protection depends on everyone
The weather predictions for Asia in 2050 read like a script from a doomsday(世界末日,最后审判日)movie. Many climatologists and green groups fear they will come true unless there is a concerted global effort to rein in greenhouse gas emissions.
In the decades to come, Asia -- home to more than half the world"s 6.3 billion people -- will lurch(突然倾斜)from one climate extreme to another, with impoverished farmers battling droughts, floods, disease, food shortages and rising sea levels.
"It"s not a pretty picture," said Steve Sawyer, climate policy adviser with Greenpeace in Amsterdam. Global warming and changes to weather patterns are already occurring and there is enough excess carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come.
Already, changes are being felt in Asia but worse are likely to come, Sawyer and top climate bodies say, and could lead to mass migration and widespread humanitarian crises. (人道主义危机)
According to predictions, glaciers will melt faster, some Pacific and Indian Ocean islands will have to evacuate or build sea defenses, storms will become more intense and insect and water-borne diseases will move into new areas as the world warms.
All this comes on top of rising populations and spiraling demand for food, water and other resources. Experts say environmental degradation(环境恶化) such as deforestation(森林砍伐) and pollution will likely magnify the impacts of climate change. In what could be a foretaste of the future, Japan was hit by a record 10 typhoons and tropical storms this year, while two-thirds of Bangladesh, parts of Nepal and large areas of northeastern India were flooded, affecting 50 million people, destroying livelihoods and making tens of thousands ill. The year before, a winter cold snap(寒流,寒潮,骤冷)and a summer heat wave killed more than 2,000 people in India.
59. Which of the following has the similar meaning to rein in?
A. slow down, control B. increase, enhance C. bring in D. take in
60. According to the passage, which one is true?
A. The changes of weather will never lead to mass migration and widespread humanitarian crises.
B. The number of the population in Asia is the largest of all continents.
C. Global warming and changes will happen in the near future if we don’t take any actions.
D. Deforestation and pollution will not magnify the impacts of climate change.
61. The reason why glaciers will melt faster is that
A. there is more and more carbon dioxide and other greenhouse gases in the atmosphere.
B. there is less carbon dioxide and other greenhouse gases in the atmosphere
C. the weather changed suddenly.
D. The reason is still unknown.
62. This passage is mainly about .
A. what kind of weather we like best.
B. the whole world will not be suitable for us to live in.
C. how to improve our environment.
D. the weather predictions for Asia in the future and the reasons.

Scientists in Canada say big ocean fish have almost disappeared from the world since the start of

The study took ten years. The researchers gathered records from fishing businesses and governments around the world. The magazine Nature published the findings.
The scientists say the common method called long line fishing is especially damaging to populations of large fish. This method involves many fishing lines connected to one boat. These wires can be nearly one hundred kilometers long. They hold thousands of sharp metal hooks to catch fish.
Long line fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one hundred hooks. But long line fishing boats now might only catch one fish per hundred hooks.
The scientists say industrial fishing can destroy groups of fish much faster than in the past. The study suggests that whole populations can disappear almost completely from new fishing areas within ten to fifteen years.
Ransom Myers and Boris Worm of Dalhousie University in Nova Scotia led the study with the University of Kiel in Germany. Worm says the destruction could lead to a complete reorganization of ocean life systems. Meyers says the decreased numbers of large fish are not the only worry. He says even populations that are able to reproduce do not get the chance to live long enough to grow as big as their ancestors. He says not only are there fewer

Scientists in the United States have developed a method that may help to predict earthquakes earlier. They say it could give people who live in deadly earthquake areas enough warning to leave before an earthquake occurs.
Currently, the most modern systems for predicting earthquakes find them only a short time before the event. Like most strong earthquakes, Wenchuan earthquake in 2008 and Haiti earthquake in 2010 were not identified early enough for people to flee the area, killing hundreds and thousands of people.
But scientists who study earthquakes are reporting that new technology could measure very small changes in the Earth’s surface.
Scientists performed experiments along California’s San Andreas Fault, an area famous for its earthquakes. Highly sensitive electrical

If additional tests confirm the changes are linked to earthquakes, the scientists believe their equipment could be used for early warning systems. A system that provides a warning signal ten hours before a major earthquake could help move people from the area and save lives.
The scientists now hope they can find earthquakes with even greater intensity by placing their equipment deeper in the ground.
71. What’s the best title for the passage?
A.A new way to help predict earthquakes.
B.The earthquakes in the world
C.A better understanding of earthquake
D.Scientists and modern systems of earthquakes
72.If the new method does work, _______.
A.fewer earthquakes will break out
B.rescue workers can save more buried people in ruins
C.a warning can be given at least ten days before the major earthquake
D.fewer people will be killed in an earthquake
73.According to the passage, the devices can predict the earthquake by______
reaching the center of the earthquake
detecting the temperature changes in the earth’s crust
measuring changes in air pressure on the Earth’s surface
recording sound waves under the ground
74.We can infer from the passage that ______.
the equipment is perfect enough to be used in practice
it’s unknown if greater earthquake can be predicted by the equipment
the deeper the equipment is placed, the more accurate the measurement is
the equipment has helped save many lives in the earthquake in Haiti .
75.How many earthquakes are mentioned in the passage?
A. One B. Two C. Three D. Four
Excused from recycling(回收利用) because you live in a high rise with a rubbish chute (垃圾道)? You won"t be for long. Miami"s Mark Shantzis has made it simple for those living in tall buildings to use the chute and recycle too .
In Shantzis" Hi-Rise Recycling System, a chute leads to a pie-shaped container with six boxes that can turn around when operated. The system , which fits in the same space as the chute and container now in use, enables glass , plastic , paper , metal , and other rubbish to go into separate boxes .
The system is controlled from a board next to the chute door. The board has a button for each class of recycling materials (as well as for unrecyclables). At the press of a button, a microcomputer locks all other floors" chute door and sets the recycling container turning until the right box comes under the chute. The computer also counts the loads and gives a signal by phone when the box is full. And a particular piece of equipment breaks up the nonrecyclables
Sorting(分类) recyclables before they are collected saves the use of expensive materials recovery equipment which otherwise has to do the sorting . Such equipment often makes recycled materials very expensive, so expensive that tons of recyclables remain wasted . Shantzis believes his system could help recycled materials become more cost-effective.
