题目列表(包括答案和解析)
The government of Norway is planning to build an unusual storage center on an island in the Arctic Ocean. The place would be large enough to hold about two million seeds. The goal is to present all crops known to scientists. The British magazine New Scientist published details of the plan last month. The structure will be designed to protect the world’s food supply against nuclear war, climate change and other possible threats. It will be built in a mountain on the Norwegian island of Spitsbergen. The mountain is less than one thousand kilometers from the North Pole, the northernmost position on earth.
An international group called the Global Crop Diversity Trust is working on the project. The director of the group, Cary Fowler, spoke to New Scientist. He said the project would let the world rebuild agriculture if, in his word, “the worst came to the worst”. Norway is expected to start work next year. The project is expected to cost three million dollars. Workers will drill（钻孔） deep in the side of a sandstone mountain. Temperatures in the area never rise above 0??C. The seeds will be protected behind walls a meter thick and high-security door.
The magazine report says the collection will represent the products of ten thousand years of farming. Most of the seeds at first will e from collections at seed banks in Africa, Asia and Latin America. To last a long time, seeds need to be kept in very low temperatures. Workers will not be present all the time. But they plan to replace the air inside the storage space each winter. Winter temperatures on the island are about eighteen degrees below 0??C. The cold weather would protect the seeds even if the air could not be replaced.
Mr. Fowler says the proposed structure will be the world’s safest gene bank. He says the plant seeds would only be used when all other seeds are gone for some reason. Norway first put forward the idea in the 1980s. But safety concerns delayed the plan. At that time, the Soviet Union was meeting in Rome of the Food and Agriculture Organization.
The project is meant to ______.
A．increase the world’s food output in the future
B．carry out some scientific experiments on plant genes
C．build an exhibition centre of the world’s plant seeds
D．protect crop seeds from dying out in case of possible disasters
Which of the following statements is TRUE according to the above passage?
A．The government of Norway will perform the project alone.
B．Seeds to be collected there were produced ten thousands years ago.
C．Spitsbergen is chosen because it is free of the nuclear war forever.
D．Temperature is a major consideration when choosing the storage place.
We can infer from the text that _______.
A．Norway had meant to build the storage centre about 20 years before.
B．The storage center will greatly promote world agriculture
C．People will get newly-developed seeds from the center every year.
D．There haven’t been any seed storage centres in the world before.
What is probably the best title of the passage?
A．The Best Place to Store Seeds
B．Noah’s Ark（诺亚方舟）of Plant Seeds in Plan
C．Concerns of World Food Supply
D．A New Way to Feed the World

For many years there’s been a debate about rewarding our children. Does it work? Is it effective?
Some people think we should establish a standard with our kids and give them something for meeting this standard as a reward. Punishment is given out in much the same way, but it’s used when certain standards of performance, behavior, etc. have not been met. Kids will often become more dutiful when threatened with punishment, and work harder when promised a valuable reward. The problem is what happens when you aren’t around.
To develop responsible, self-disciplined kids, parents need to promote certain ideas. One of these ideas is that everyone pitches in and helps in your family. Another idea is that there can be enjoyment in doing any task if we choose to make it so. When a task is for a worthy cause ( our family can enjoy the house more because I helped clean it), this message can have a big impact.
This is how we help our kids develop a sense of responsibility. When our children develop this responsibility, they’ll be more disciplined, and they’ll control their emotions better. When we give rewards to our kids, we reduce the sense of responsibility. We also create children who may temporarily perform to a certain standard, but who aren’t likely to continue the performance without the carrot hanging in front of them.
“Rewards and punishment can change behavior for a while, but they cannot change the person who engages in the behavior,” said Alfie Kohn, author of Punished by Rewards. “Good values have to be grown from the inside out.” Parents can help give their children a sense of shared responsibility and discipline which can last a life time. The real rewards that your children receive will be their readiness for the complex and demanding world that waits for them—a world that rewards those who have learned the secrets of discipline responsibility. So keep those shiny rewarding to yourself, and let your kids find their own rewards.

| A．they may lose interest in their work |
| B．they may appear to be well-behaved |

How can a creature weighing over 5 tons and normally taking 150 kilograms of food and 120 liters of water per day survive in a desert environment?
In the southwest African country of Namibia,and the Sahara lands of Mall further north,the desert elephant does just that.
Although not regarded as a separate species from the African elephant,the desert cousin differs in many ways.Their bodies are smaller,to absorb less heat,and their feet are larger for easier walking across sandy surfaces.They are taller,to reach higher branches.They have shorter tusks(象牙),and most importantly,longer trunks to dig for water in riverbeds.
Desert elephants can travel over 70 kilometers in search for feeding grounds and water-holes,and have a larger group of families.They drink only every 3-4 days,and can store water in a “bag” at the back of their throat,which is only used when badly needed.Desert elephants are careful feeders—they seldom root up trees and break fewer branches,and thus maintain what little food sources are available.Young elephants may even eat the dung(粪便) of the female leader of a group when facing food shortage.
During drought they are unlikely to give birth to their young but with good rains the birthrate will increase greatly.Desert elephants have sand baths,sometimes adding their own urine(尿液) to make them muddy!
As we continue to overheat our weak planet,it can only be hoped that other animal species will adapt as extraordinarily well to change as the desert elephant.
The underlined part in Paragraph 2 means “_______”.
A.remains in the African countries
B.drinks 120 liters of water a day
C.manages to live in desert areas
D.eats 150 kilograms of food daily
Desert elephants are called careful feeders because they ______.
A.rarely ruin trees
B.drink only every 3-4 days
C.search for food in large groups
D.protect food sources for their young
The author answers the question raised in the first paragraph with ______.
A.stories and explanation
B.facts and descriptions
C.examples and conclusion
D.evidence and argument
What can be inferred from the last sentence in the passage?
A.Overheating the earth can be stopped.
B.Not all animal species are so adaptable.
C.The planet will become hotter and hotter.
D.Not all animals are as smart as desert elephants.
Fire fighting is a serous matter, knowing what to do during a fire can save people’s lives. It is important to know the ways you can use and show them to everyone else in the family, such as stairways and emergency exits, but not elevators.
From the lower floors of building, escape through windows is possible. Learn the best way to get out from a window with the least chance of serious injury.
The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about 6 feet to the ground. It is about twice the height of an average man. Of course, it is safer to jump a short way down than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked into the room.
On the second or third floor, the best windows for escape are those which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury. Bushes and trees can help you to have a soft landing.
【小题1】Which of the following should not be used when trying to escape from a fire?
| A．Windows | B．Elevators | C．Fire exits | D．Stairways |
| A．about 12 feet | B．about 6 feet |
| C．about the height of an average man | D．nearly 10 feet |
| A．the only way | B．the best way |
| C．safer than any other ways | D．one of the possible ways |
| A．breathing in smoke might be harmful | B．smoke will enter the room through an open window |
| C．fresh air can’t reach the second floor window | |
| D．to keep you head low will help you to escape a fire |
| A．drop directly onto the ground | B．first drop onto a roof then onto the cement |
| C．drop from a roof window then onto bushes and trees | |
| D．drop onto the cement rather than bushes and grass |
