Some spiders hunt on the ground, others build webs to trap their food, but the grass water spider catches its prey by running along the surface of the water.
This special water spider lives on the grassy banks of streams where mosquitoes, damsel flies and other insects come to feed and breed.
Although it is one of the largest spiders in New Zealand, it has an unusual ability. It doesn’t disturb the water as it waits for its meal, and there is barely a ripple(波纹) when it skims(掠过) across the surface at lightning speed to catch its prey.
Grass water spiders deal swiftly with larger insects like damsel flies by pulling their heads under the water and holding them there until they drown.
After a meal, the grass water spider spends up to half an hour grooming(修饰) itself. It wipes its eight eyes, brushes its antennae(触角), and takes special care to clean the hairs on its body.
It is the hairs that trap tiny bubbles(泡沫) of air so that the spider can run down a blade(叶片) of grass and stay underwater for up to an hour when it is frightened. The hairs also keep the spider dry, even underwater.
It is only when the female spider is caring for the young that she does not hunt on the water. After mating, she produces a large egg sac(囊), which she carries around for five weeks. Once the eggs start to hatch, she attaches the sac to some blades of grass or a thistle. She then tears the sac open and releases the tiny spiders into the nursery web.
How does the grass water spider kill its prey?
A. in a web B. by drowning C. by poisoning D. with its antennae
the writer describes the special spider as “special” because _______.
A. it walks on water B. it has eight eyes
C. of its hairy appearance D. of the way it produces its young
The passage tells us that the spider ______.
A. feeds grass and thistles to its young.
B. lives on blades of grass under the water
C. lives in the grass on the banks of streams
D. eats a meal once every five weeks
The purpose of the passage is to _______.
A. convince readers that spiders are dangerous
B. indicate that the grass water spider is endangered
C. list all of the spiders that can be found in New Zealand
D. describe the characteristics of the grass water spider

(D)
Malaria, the world's most widespread parasitic（寄生虫引起的）disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't （or can't） seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the 
Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect （感染）. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth—and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.
76. According to paragraph 1, many people don't seek care because _______.
A. they are too poor
B. it is unusual to seek care
C. they can remain unaffected for long
D. there are too many people suffering from the disease
77. People suffering from malaria _______.
A. have to kill female mosquitoes B. have ability to defend parasites
C. have their red blood cells infected D. have sudden fever, followed by chills
78. Which of the following may be the reason for the wide spread of the disease?
A. Its resistance to global warming.
B. Its ability to pass on the virus frequently.
C. Its outbreaks in cities with large populations.
D. Its ability to defend itself and resist new drugs.
79. It can be inferred from the passage that _______. .
A. no drugs have been found to treat the disease
B. the alternative treatment is not easily available to most people
C. malaria has developed its ability to resist parasites
D. nobody knows what will be the drug to treat the disease
80. Which of the following questions has NOT been discussed in the passage?
A. How can we know one is suffering from malaria?
B. How many people are killed by malaria each year?
C. Why are there so many people suffering from malaria?
D. What has been done to keep people unaffected for long?

A subject which seems to have been insufficiently studied by doctors and psychologists is the influence of geography and climate on the psychological and physical health of mankind. There seems no doubt that the general character of the landscape, the relative length of day and night, and the climate must all play a big part in determining what kind of people we are.
It is true that a few studies have been made. Where all the inhabitants of a particular area enjoy exceptionally good or bad health, scientists have identified contributory factors such as the presence or absence of substances like iodine, fluoride, calcium, or iron in the water supply, or perhaps types of land that provide breeding places for pests like mosquitoes or rats.
Moreover, we can all generalize about types of people we have met. Those living in countries with long dark winters are apt to be less talkative and less vivacious than inhabitants of countries where the climate is more equable. And where the olive and the orange grow, there the inhabitants are cheerful, talkative, and spontaneous.
But these commonplace generalizations are inadequate: the influence of climate and geography should be studied in depth. Do all mountain dwellers live to a ripe old age? Does the drinking of wine, rather than beer, result in a sunny and open temperament? Is the strength and height of one of the Kenyan tribes due to their habitual drinking of the blood of cows?
We are not yet sure of the answers to such questions, but let us hope that something of benefit to mankind may eventually result from such studies.

As China becomes increasingly urbanized (城市化), it has to find space for its urban and
rural citizens as both groups become increasingly integrated. Experts suggest a possible model
way may be “re-inventing” a “garden city”.
China’s mega-cities are bursting at the borders and the country is now undergoing the quickest and biggest urbanization in the history of mankind. It is estimated that by 2025, China will have 400 million more people living in its cities, raising its urban population to 900 million. Besides, new satellite towns are mushrooming on the urban fringes while city ring roads are rippling outwards into the countryside at amazing speed. Satellite maps collected by Professor Joshua Bolchover at the University of Hong Kong bring the problem sharply into focus. They track the changing rural-urban framework in the past 30 years, and suggest that cities are cruelly destroying surrounding rural land and rapidly reducing the amount of arable（可耕种的）land, which gives way to new residential blocks, new industrial zones, new financial centers and the other inevitable signs and signatures of economic growth.
This, however, is not sustainable growth pattern, especially when China has the world’s largest population to feed. So concerned urban planners are starting to note the social and physical effects of diaspora（大移居）when replaced rural communities are forced into the cities.
On the other hand, a trend of thought is gradually taking shape and this is the concept of the “garden city”, a combination of country and city that is being proposed by architects and city planners. Hua Li, from Tao Architects, is among the many professionals with such a voice. His argument is supported by a long-term study on this subject. As Hua says, the answer is to preserve patches of productive farmland within urban boundaries. Less transportation means we have fresh agricultural products at lower costs and less carbon emission in the city. And urban farmland can also be showcased for agricultural tourism and education.
The concept is already practiced at the grassroot level. Agriculture has gone into the air, up to roof and balcony in some communities in the cities. It’s common to see organic “hanging garden” on the roof of some traditional courtyard home. According to some people, the rooftop project translate to tangible (=" practical)" benefits, such as safe, nutritious vegetables, a cooler home in summer. Some say thanks to the tomatoes they plant that are natural insect killers, there’re fewer mosquitoes. Apart from these, it also contributes to better bonding with neighbors. Zhang, a doctor in Beijing, began creating his hanging garden five years ago. Since his garden became home to 30 kinds of vegetables and fruit --- all enough to feed his family, neighbors have enjoyed dropping by for a relaxing chat or just to see how well the lovely vegetables and fruit are doing.
Although people like Zhang are still rare and the greening of roof space with vegetables and fruit takes skill and energy, with more positive media exposure and advanced technology there is the prospect that garden city will become common practice in the near future. By then, cities will no longer look so gray when seen from the satellites.
【小题1】What is the purpose of paragraph 2?
| A．To show the experts’ concern about the increase of population. |
| B．To persuade people into supporting economic growth in cities. |
| C．To explain the reasons for the change of rural-urban framework. |
| D．To inform the readers of the consequences of quick urbanization. |
| A．benefit the environment and lower living costs |
| B．become a project that needs a long-term study |
| C．lead to more rural communities being replaced |
| D．attract more farmers to take tours in cities |
| A．he achieves his dream to own a hanging garden |
| B．hanging gardens are becoming more popular |
| C．the garden contributes to a better neighborhood |
| D．he is a pioneer to practise the gardening concept |
| A．desperate | B．hopeful | C．disappointed | D．concerned |

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
It’s summertime-time once again for mosquitoes to make their appearance. And once they appear, mosquitoes are a total pain. They land on you, bite you, suck out some blood and leave behind an itchy welt（发痒的红肿）.
1 Female mosquitoes must find blood in order to reproduce, so mosquitoes come equipped with finely tuned sensors to help them locate the blood they need.
Mosquitoes’ weapons
Mosquitoes have perfected three different types of sensors. First, mosquitoes can sense several different chemicals. Mosquitoes can smell carbon dioxide and lactic acid（乳酸）up to 100 feet away. 2
Second, mosquitoes have very good eyesight. If you are wearing clothing that contrasts with the background, and if you move while wearing that clothing, mosquitoes can see you. It’s a good bet that anything moving is alive, and therefore full of blood.
Finally, mosquitoes come equipped with temperature sensors, so they can find warm-blood mammals and birds very easily.
3 The female mosquito sticks her proboscis（喙）into you. She sucks about five microliters of your blood into her abdomen.
After she has bitten you, some saliva（唾液）remains in the wound. 4 The area swells and you tich. Eventually, the selling goes away, but the itch remains until your immune cells break down the saliva proteins.
Our defense methods
Because mosquitoes are both a nuisance（讨厌的东西） and a danger, people prefer to stay away from mosquitoes. One way to do that is to use a chemical called DEET, which seems to black a mosquito’s chemical sensors. 5 In some cities there are even trucks that drive around town to spray for mosquitoes. Finally there are to traps. The most popular traps turn propane（丙烷） into carbon dioxide and warmth to attract mosquitoes. Over time, by catching large numbers of mosquitoes, these traps can cause the collapse of the mosquito population in the area.
A．Another way to control mosquitoes is with insecticides（杀虫剂） that kill them.
B．How mosquitoes work is unknown to most of us.
C．Once a mosquito lands on you, it is time to bite.
D．Some bites of mosquitoes are more serious than you thought.
E. Mammals and birds give off these gases as part of their normal breathing.
F. The proteins from the saliva create an immune response from your body.
G. But if you ignore the fact that mosquitoes are so annoying they really are amazing.
