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 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 costs 175,000 dollars. The second costs 150,000 dollars.

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

A.$150,000~$175,000. B.$150,000~$30,000.

C.$30,000~$35,000. D.over $75,000.

2.Besides milking cows,the robotic system also can ________.

A.judge the quality of fresh milk

B.keep fresh milk for two weeks

C.adjust the temperature of milking stations

D.improve the appetite of cows

3.Why is the robotic system not popular now?

A.Because it usually causes the waste of milk.

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

C.Because young people have no interest in it.

D.Because people can't afford to buy it.

4.From the first paragraph,we can infer ________.

A.cows can be raised by robots in the future

B.robots direct cows into milking stations

C.the robotic system is designed to reduce labor

D.cows are kept clean by robots on some farms

Winter begins in the north on December 22nd. People and animals have been doing what they always do to prepare for the cold months. Squirrels, for example, have been busy gathering nuts from trees. Well, scientists have been busy gathering information about what the squirrels do with the food they collect.

They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut trees. The black walnut is the nut of choice for both kinds of squirrels. The black walnut tree is also a central part of some hardwood forests.

Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student now at the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels. Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. But they seldom remember where they buried every nut. So some nuts remain in the ground. Conditions are right for them to develop and grow in the following spring. Red squirrels, however, store large groups of nuts above ground. Professor Swihart calls “death traps for seeds”.

Gray squirrels are native to Indiana. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century.

The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause.

1.The study done by Rob Swihart and Jake Goheen is to ________.

A. find out the living conditions for squirrels

B. do something to get rid of squirrels

C. save the forests in the American state of Indiana

D. learn squirrels’ influence on black walnut trees

2. The difference between gray squirrels and red squirrels mainly lies in ________.

A. the way they store the walnuts

B. the way they gather the walnut

C. the number of the nuts they can collect

D. the fact that the gray squirrels have a bad memory

3. When Professor Swihart says “death traps for seeds”, he actually means that ________.

A. red squirrels eat more nuts than gray squirrels

B. nuts above the ground will not develop into plants

C. gray squirrels and red squirrels will have severe fights

D. seeds can be traps for other animals in the forest

4.According to the passage, which of the following is true?

A. Gray squirrels do more harm to the forest than red squirrels.

B. Red squirrels and gray squirrels have helped the spread of walnut trees.

C. Human beings should bear some responsibility for the decreasing number of gray squirrels.

D. The cleaning of forest land benefits gray squirrels directly.
