一、阅读理解
How does an ecosystem(生态系统) work What makes the populations of different species the way they are Why are there so many flies and so few wolves To find an answer, scientists have built mathematical models of food webs, noting who eats whom and how much each one eats.
With such models, scientists have found out some key principles operating in food webs. Most food webs, for instance, consist of many weak links rather than a few strong ones. When a predator(掠食动物) always eats huge numbers of a single prey(猎物), the two species are strongly linked; when a predator lives on various species, they are weakly linked. Food webs may be dominated by many weak links because that arrangement is more stable over the long term. If a predator can eat several species, it can survive the extinction of one of them. And if a predator can move on to another species that is easier to find when a prey species becomes rare, the switch allows the original prey to recover. The weak links may thus keep species from driving one another to extinction.
Mathematical models have also revealed that food webs may be unstable, where small changes of top predators can lead to big effects throughout entire ecosystems. In the 1960s, scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other species—including species they did not directly attack.
And unplanned human activities have proved the idea of top-down control by top predators to be true. In the ocean, we fished for top predators such as cod on an industrial scale, while on land, we killed off large predators such as wolves. These actions have greatly affected the ecological balance.
Scientists have built an early-warning system based on mathematical models. Ideally, the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown or would even allow us to pull an ecosystem back from the borderline. Prevention is key, scientists say because once ecosystems pass their tipping point(临界点), it is remarkably difficult for them to return.
1. What have scientists discovered with the help of mathematical models of food webs
A. The living habits of species in food webs.
B. The rules governing food webs of the ecosystems.
C. The approaches to studying the species in the ecosystems.
D. The differences between weak and strong links in food webs.
2. A strong link is found between two species when a predator ________.
A. has a wide food choice
B. can easily find new prey
C. sticks to one prey species
D. can quickly move to another place
3. What will happen if the populations of top predators in a food web greatly decline
A. The prey species they directly attack will die out.
B. The species they indirectly attack will turn into top predators.
C. The living environment of other species will remain unchanged.
D. The populations of other species will experience unexpected changes.
4. How does an early-warning system help us maintain the ecological balance
A. By getting illegal practices under control.
B. By stopping us from killing large predators.
C. By bringing the broken-down ecosystems back to normal.
D. By signaling the urgent need for taking preventive action.
二、完形填空
Early spring can be a tough time in the Midwest. It can 1 both people and animals with its unexpected snowstorms.
Every spring, migratory(迁徙的) birds camp out in a large pond near my house on the way to their summer 2 . This year, besides geese, scaups, a type of diving duck spent days hanging out 3 eats. Then a snowstorm hit, followed by a very 4 night.
The next morning, I was shocked to see that all birds had 5 overnight—except one lone female, who was diving 6 and dynamically in the circle of open water. Her movement and body heat had kept the 7 from coming close as I 8 her from my warm house.
However, as the temperature dropped, the open water got smaller, and her movements slowed. I watched with 9 as she eventually stopped moving, fearing that something might happen.
And then it happened: Two more ducks appeared, 10 next to her still body. More ducks came and the circle of water came alive with their splashing and diving. Slowly, the circle of water 11 in size. Within minutes, the lone female was revived by her friends’ presence.
This little duck wouldn’t have 12 another night without her friends. She, in turn, had kept that area of water 13 , so her friends had a place to stop and 14 themselves. Sometimes, a tiny action—even our mere 15 —might brighten one’s day, and even save one’s life.

四、答案：
Dear Sir or Madam,
I'm writing to give some suggestions to protect the wildlife living in and around our city. As we know, many species of wildlife are in danger of extinction. This is because the environment that they are living in has been destroyed greatly.
With the development of cities, water and air are seriously polluted. Their living areas are becoming smaller and smaller. They not only have little to cat, but also can be killed by human beings. These species of wildlife are important part of our life. Personally, more measures should be taken to protect them from being hurt. Firstly, more laws must be made to stop people from cutting down trees. Secondly, all the factories must clean the waste water before it is poured into rivers or lakes. Thirdly, more reserves should be set up so that they can live safely.
I hope my suggestions are of much help.
Yours sincerely,
Li Hua
