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．a(chǎn)djust 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

Elizabeth Freeman was born about 1742 to African American parents who were slaves. At the age of six months she was acquired, along with her sister, by John Ashley, a wealthy Massachusetts slaveholders. She became known as “Mumbet” or “Mum Bett.”

For nearly 30 years Mumbet served the Ashley family. One day, Ashley’s wife tried to hit Mumbet’s sister with a spade(鐵鍬). Mumbet protected her sister and took the blow instead. Angry, she left the house and refused to come back. When the Ashleys tried to make her return, Mumbet turned to a lawyer, Theodore Sedgewick. With his help, Mumbet sued(起訴) for her freedom.

While serving the Ashleys, Mumbet had listened to many discussions of the new Massachusetts laws. If the laws said that all people were free and equal, then she thought it should apply to her. Eventually, Mumbet won her freedom—the first slave in Massachusetts to do so under the new law.

Strangely enough, after the trial, the Ashleys asked Mumbet to come back and work for them as a paid employee. She refused and instead went to work for Segdewick. Mumbet died in 1829, but her spirit lived on in her many generations. One of her great-grandchildren was W.E.B. Du Bois, one of the founder of the NAACP, and an important writer and spokesperson for African American civil rights.

Mumbet’s tombstone still stands in the Massachusetts cemetery where she was buried. It reads, in part: “She was born a slave and remained a slave for nearly thirty years. She could neither read nor write, yet in her own area she had no superior or equal.”

1.What do we know about Mumbet according to Paragraph 1?

A. She was born into a rich family.

B. She was a slaveholder.

C. She was born a slave.

D. She had a famous sister.

2.What did Mumbet do after the trial?

A. She founded the NAACP.

B. She went to live with her grandchildren.

C. She continued to serve the Ashleys.

D. She chose to work for a lawyer.

3.What did Mumbet learn from discussions about the new constitution?

A. How to be a good servant.

B. How to apply for a job.

C. She should always obey her owners’ orders.

D. She should be as free and equal as whites.

4.What is the text mainly about?

A. A trial that shocked the whole world.

B. The life of a brave African American woman.

C. A story of a famous writer and spokesperson.

D. The friendship between a lawyer and a slave.

閱讀下列短文，從每題所給的A、B、C、D四個(gè)選項(xiàng)中，選出最佳選項(xiàng)。

I am a vegetarian（素食主義者）．Many people are quick to think of vegetarianism as strange behavior．I treasure our Earth, and since we only have one, we should protect it and the wildlife that lives on it．But that’s only one of the reasons to be a vegetarian．

Vegetarians may live longer, healthier lives．There is a connection between red meat consumption and various diseases．From an economic standpoint, it requires less land, money and energy to produce foods for a vegetarian diet．While there are many benefits to being a vegetarian, only a handful of those who attempt to adopt this lifestyle succeed．

The most important quality required to be a vegetarian is firmness since surrounded by the temptation of meat, we tend to give up vegetarianism easily．Creativity is almost as important as commitment．It’s easy to tire of eating nothing but salad． But with a little creativity and some soy products, almost any meal can become vegetarian-friendly．

Not everyone wants to be vegetarian．Accepting this is part of being a vegetarian with style．Forcing your beliefs on others is disrespectful．Stylish vegetarians should also be able to turn down a meaty dish politely without annoying their hosts．

Being a successful vegetarian has been easy for me, but it may not be so for others．a(chǎn) common mistake is quitting before your body has adjusted to the change．It can be difficult to keep the lifestyle in the beginning because of temptation．However, it fades over time．Another common mistake is quitting because you’ve been misinformed about the nutritional wisdom of being a vegetarian．That’s why it is vital to be educateD． Countless people will tell you that it’s impossible to obtain the nutrients and protein（蛋白質(zhì)）your body requires without meat, but they are incorrect．People actually need only 44-55 grams of protein a day, and that is easily found in a vegetarian diet．Many meat eaters are consuming three times that amount, which is not beneficial．It leads to diseases．Vegetables can also supply all the vitamins, minerals and nutrients your body needs．However, if you’re still not convinced, you can take a multi-vitamin．

1.According to the passage, being a vegetarian helps ______．

A． protect the wildlife

B． free people from diseases

4.Which of the following is NOT true?

A． Many people give up before their bodies can adjust to the transition．

B． Many people quit because they’re poorly educated about nutrition．

C． Consuming 150 grams protein a day can be harmful．
