Farmers can produce more by planting several different crops in the same field.But their success depends on which crops they plant together and how they mix (混合) them in the filed.In the past, the only way the farmers could learn which crops grow best together is to plant them and wait for the results.Now, however, a computer can give them answers.A new computer program written by Dr John Vanderwell of Michigan University can tell a farmer which plants grow well together and which do not.It can tell him how to plant the different crops; if he should plant each in a separate row, or mix the crops in the same row.It can tell the farmer how changes in planting each of the crops will affect the production of all of them.And it can tell him which plants can help reduce losses (损失) from diseases.

1.Which of the following best gives the main idea of the passage?

A．Computer helps find the best program for mixing plants.

B．Computer helps produce more crops.

C．Computer helps protect against insects and diseases.

D．Computer helps grow different plants.

2.According to the passage, to get the best result, one needs to choose carefully ________.

A．the kinds of crops to be planted together

B．the way for different crops to be mixed

C．both A and B

D．either A or B

3.It seems the new computer program can NOT tell us ________.

A．whether we should grow cotton and tomato together

B．how we should plant cotton and tomato together

C．what will happen if we grow potato, instead of tomato, together with cotton

D．how we can grow rice in the tomato field

4.The new computer program seems most useful in saving us ________.

A．man power        B．seeds             C．time             D．land

5.Which of the following is NOT true?

A．Computers can tell farmers how many plants can grow together.

B．With the help of computers farmers don't have to do a lot of work.

C．With the help of computers farmers can get better results.

D．The change of one plant may cause a change in production.

Ever since farmers began to grow grain, they have had to protect their crops from birds. In the 1300's, English farmers hired children to protect their crops. They were called “bird scares”. The children chased birds and threw stones at them.

Bird scares were replaced in the 1800's by scarecrows. A scarecrow is anything that is set in a field to scare birds away. Often it is a pole dressed like a person. Some farms with small fields still use scarecrows today.

Farming became big business in the twentieth century. Scarecrows could no longer protect the huge fields of grain, so farmers used poisonous chemicals on the fields. The poison made the grain bitter. The birds usually would not eat the bitter grain.

Although they can prevent crops from being destroyed by insects and birds, some chemicals can be harmful to humans. Therefore, farmers are using fewer chemicals now than they did twenty years ago. Perhaps scarecrows may be seen more often in the fields in the future.

1.English farmers began to hire children to get away birds since_____.

2.“Bird scares” keep birds away from crops by_____.

3.Which statement from the passage supports the idea that scarecrows may be seen more often in the fields in the future?

4.The author's purpose is to ________.

Technology is making life easier for some dairy farmers．They use robotic systems to milk their cows．Cows are trained to follow a series of paths that lead to milking stations．Only one cow at a time can enter a station．

Once inside，the cow is rewarded with food．As the cow eats，a  robotic arm cleans and connects the animal to the milking machine．A few minutes later，milking is complete．The gate is opened，the cow is released and the next cow enters．

The robotic systems are designed to operate 24 hours a day．The cows get to decide when they want to be milked．Cows are milked an average of about three times a day．Some are milked four to six times a day．

The cows wear collars around their necks that identify them to the system．A computer keeps records on their eating and milking．A cow is released from the station if the computer decides it should not be milked．

The automated system also measures the temperature and color of freshly produced milk．Milk is thrown away if it does not pass the tests．

Professor Plaut believes the systems will appeal（吸引） especially to the next generation of farmers．She means young people who are more interested in technology and less interested in working all the time on the farm．Still，she says the price of robotic milking systems will continue to limit their use．

Doug and Tina Suhr have more than 100 cows on their family farm．Last year it became the fourth farm in southeast Minnesota to get a robotic milking system．A recent story in a local agricultural newspaper said the first robot cost 175 000 dollars．The second cost 150 000．

Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot．He says the increase in milk production reaches a high of more than six kilograms per cow per day．

1.From the first paragraph，we can infer________．

A．the robotic system is designed to reduce labor

B．cows can be raised by robots in the future

C．robots direct cows into milking stations

D．cows are kept clean by robots on some farms

2.Besides milking cows，the robotic system also can______．

A．adjust the temperature of milking stations

B．judge the quality of fresh milk

C．improve the appetite of cows

D．keep fresh milk for two weeks

3.Why is the robotic system not popular now?

A．Because young people have no interest in it．

B．Because it is difficult to learn how to use it．

C．Because people can’t afford to buy it．

D．Because it usually causes the waste of milk．

4.According to Doug，what is the wage of an employee?

A．150 000～170 000．                    B．750 000．

C．150 000～30 000．                     D．30 000—32 000

5.The best title for the passage may be_________．

A．Letting robot milk your cow               B．Milking cows by hand

C．Improving the quality of milk               D．Drinking fresh milk every day

Fruit farmers in Okayama, Japan, have managed to make peeling (去皮) a banana optional by developing a special variety with eatable skin. The peel of their “Mongee bananas” isn’t particularly tasty, but it’s much thinner and far less bitter than that of regular bananas, making it 100% eatable.

Scientists at D&T Farm in the country’s Okayama Prefecture released the social media-ready news following months of experimenting with a freezing-and-thawing (解冻) method, which keeps the banana tree at extremely cold temperatures followed by a dramatic heat increase. The result is soft and thin skin that hasn’t fully developed. They froze young banana trees to -60 degrees Celsius, planting them again as they began to thaw. This apparently activated an ancient part of their DNA, which not only allows the plant to grow in Japan’s cool climate, but also speeds up its development. While tropical varieties of bananas require two years to grow large enough for consumption (消费), the Mongee banana needs just four months.

The first bunch of Mongee bananas hit department stores’ shelves in the November of last year, but getting your hand on one of these incredible fruits remains a huge challenge. D&T Farm only produces 10 bananas per week, and they only deliver them to the Fruit Corner of Tenmanya Okayama, a local department store. But even if you happen to find one available, you’d probably be a bit put off by the price – 648 yen ($5.70) per fruit.

Banana peel is an excellent ingredient that can contain vitamin B6 and magnesium related to the production of serotonin (血清素). At the same time, it has a positive effect on both brain and sleep. Research results that ripe fruit peels have a good effect on treating prostatic hypertrophy (前列腺肥大) have also been published.

John Guterman, a botanist, says, “And what about shipping? For most of the fruit’s history, the peel has provided protection, allowing it to travel long distances. A softer, more bruise-prone banana would be a step back from hardy banana varieties that travel thousands of miles. In this sense, the day we all stop peeling bananas and instead bite straight through their skin may still be a long way away.

1.Compared with regular bananas, Mongee bananas ________.

A.are far easier to peel B.have much sweeter flesh

C.are much more thin-skinned D.have a longer growth period

2.Why is it hard to buy a Mongee banana now?

A.It isn’t affordable at all. B.It hasn’t come into the market yet.

C.It is made for certain people. D.Its production ability is still limited.

3.What does Paragraph 4 mainly talk about?

A.The medical value of banana peel.

B.The nutrition (营养) of banana peel.

C.The way of making banana peel sweeter.

D.The studies about how to make banana peel eatable.

4.What does John think of the Mongee banana?

A.It should not be widely grown.

B.It won’t be spread widely soon.

C.It indicates the future of fruits with skin.

D.It has no advantage over regular bananas.

Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants produce volatile compounds (挥发性化合物) —— chemicals that easily change from a liquid to a gas. A flower’s sweet smell, for example, comes from such volatile compounds to attract insects such as bugs and bees.

Plants can also discover  volatile compounds produced by other plants. A tree under attack by hungry insets, for instance, may give off these chemicals in order to let other trees know about the attack. In response, the other trees may send off their chemicals to keep the bugs away —— or even chemicals that will attract the bugs’ natural enemies.

Now scientists have created a quick way to understand what plants are saying: a chemical sensor (传感器) called an “electronic nose”. The “e-nose” can tell such compounds as plants make. When plants are attacked, scientists say, the e-nose could help quickly decide whether plants are being eaten by insects. But today, the only way to spot such insects is to inspect individual plants by observing them. This is a challenging task for managers of greenhouses, including those that can house thousands of plants. The research team is working with an e-nose that can recognize volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds based on the interactions (相互作用), and then the e-nose will give off electronic signals that the scientists can analyze by using computer software.

To test the e-nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all being common greenhouse crops. Then scientists collected samples of the air around damaged leaves from each type of crop. These plants had been damaged either by insects or by scientists who made holes in the leaves with a hole punch (打孔器).

The e-nose, it turns out, can identify healthy cucumber, pepper and tomato plants based on the volatile compounds they produce. It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage —— by insects or with a hole punch —— had been done to the tomato leaves.

With some fine-tuning (微调), a device like the e-nose can one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this can also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareva, a biochemist at Purdue University in West Lafayette, India, who studies smells of flowers and plants. Hopefully, scientists believe, the device can bring large benefits to greenhouse managers in the near future.

1.We learn from the text that plants communicate with each other by ______.

2.What did the scientists do to find out if the e-nose worked?

3.According to the writer, the most amazing thing about the e-nose is that it can ______.

4.We can infer from the last paragraph that the e-nose ______.

George Washington Carver had a goal. This was to help southern farmers who needed good crops. They needed crops that didn’t hurt the soil. Carver went to Simpson College in Iowa, in which he studied for three years. Then he went to Iowa State, where he got two degrees. The college knew he was smart and wanted him to stay. So he joined the team. He was put in charge of a huge greenhouse. There he grew over 20,000 kinds of fungi（真菌），which made him famous.

Carver had many job offers. Thomas Edison offered $175,000 a year. Henry Ford tried to hire him too. Joseph Stalin invited him to the Soviet Union to help with cotton. But Carver refused all offers. Instead, he took a job at Tuskegee Institute. This was a school for African Americans. Carver was paid only $1,000 a year. But he was happy because he had goals to reach and he knew he could reach them at Tuskegee.

Carver worked at Tuskegee for 47 years. He never asked for a raise in pay. And he never received one. He worked so hard that he died in his office chair on January 4, 1943.

Carver came up with over 300 products from peanuts （花生）, all of which could have been patented (申请专利). He could have made millions. But he did not want to. Here is what he said, “Mr. Creator did not charge to grow the peanut. I cannot accept money for my work with it.”

Through his efforts, Carver set up a fund, for he wanted research to continue. He gave his life’s savings to it, which came to $40,000. One honor came after his death. His birthplace was made a national shrine (圣地). How surprised the modest Carver could have been!

1.One job offer which Carver accepted was to work for ______.

A.Thomas Edison B.Henry Ford

C.Joseph Stalin D.Tuskegee Institute

2.How much did Carver offer to the fund？

A.$1,000. B.$20,000.

C.$40,000. D.$175,000.

3.Which of the following best describes Carver?

A.Selfless. B.Stubborn.

C.Stupid. D.Reliable.

4.What’s the main idea of the text?

A.Carver preferred work to money.

B.Carver devoted his whole life to achieving his goals.

C.Carver refused many job offers that would make him rich.

D.Some scientists would rather do good than make much money.
