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 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.From the first paragraph, we can infer________.

Some students get so nervous before a test; they do poorly even if they know the material. Sian Beilock has studied these highly anxious test-takers.
Sian Beilock: “They start worrying about the consequences. They might even start worrying about whether this exam is going to prevent them from getting into the college they want. And when we worry，it actually uses up attention and memory resources. I talk about it as your cognitive horsepower that you could otherwise be using to focus on the exam.”
Professor Beilock and another researcher，Gerardo Ramirez，have developed a possible solution. Just before an exam，highly anxious test-takers spend ten minutes writing about their worries about the test.
Sian Beilock: “What we think happens is when students put it down on paper，they think about the worst that could happen and they reappraise the situation. They might realize it’s not as bad as they might think it was before and，in essence(本质上)，it prevents these thoughts from popping up when they’re actually taking a test.”
The researchers tested the idea on a group of twenty anxious college students. They gave them two short math tests. After the first one, they asked the students to either sit quietly or write about their feelings about the upcoming second test.
The researchers added to the pressure. They told the students that those who did well on the second test would get money. They also told them that their performance would affect other students as part of a team effort.
Professor Beilock says those who sat quietly scored an average of twelve percent worse on the second test. But the students who had written about their fears improved their performance by an average of five percent.
Next, the researchers used younger students in a biology class. They told them before final exams either to write about their feelings or to think about things unrelated to the test.
Prefessor Beilock says highly anxious students who did the writing got an average grade of B+，compared to a B－ for those who did not.
Sian Beilock: “What we showed is that for students who are highly test-anxious，who’d done our writing intervention(排解)，all of a sudden there was no relationship between test anxiety and performance. Those students most likely to worry were performing just as well as their classmates who don’t normally get nervous in these testing situations.”
But what if students do not have a chance to write about their fears immediately before an exam or presentation? Professor Beilock says students can try it themselves at home or in the library and still improve their performance.Which of the following is TRUE?
| A．The result in the math test agrees with that in the biology test. |
| B．In the first math test, students who sat quietly performed better. |
| C．In the second math test, students who wrote about their feelings did worse. |
| D．Some college students are highly anxious test-takers while others are not in the tests. |
What may happen if students have the problem of test anxiety?
| A．Test anxiety is sure to cause students to fail the test. |
| B．Test anxiety can improve students’ performance to some degree. |
| C．Students’ attention and memory resources run out when worried. |
| D．Students may not be admitted into their favorite college if worried |
The result of the research suggests that ________．
| A．proper amount of burden may turn out to be a good thing |
| B．facing the fears bravely may help one to achieve more |
| C．avoiding facing the problem may contribute to relaxation |
| D．taking no action before difficulty may result in success |
What is the main idea of the passage?
| A．It is important for students to overcome test anxiety. |
| B．Anxious students overcome test anxiety by writing down fears. |
| C．It is a common practice for students being worried before a test. |
| D．Being worried before tests does harm to students’ performance. |
Why play games? Because they are fun, and a lot more besides, following the rules, planning your next move, acting as a team member…. These are all “game” ideas that you will come across throughout your life.
Think about some of the games you played as a young child, such as rope-jumping and hide-and-seek. Such games are entertaining and fun. But perhaps more importantly, they translate life into exciting dramas that teach children some of the basic rules they will be expected to follow the rest of their lives, such as taking turns and cooperating.
Many children’s games have a practical side. Children around the world play games that prepare them for work they will do as grown-ups. For instance, some Saudi Arabian children play a game called bones，which sharpens the hand-eye coordination（协调）needed in hunting.
Many sports encourage national or local pride. The most famous games of all, the Olympic Games, bring athletes from around the world together to take part in friendly competition. People who watch the event wave flags, knowing that a gold medal is a win for an entire country, not just the athlete who earned it. For countries experiencing natural disasters or war, an Olympic win can mean so much.
Sports are also an event that unites people. Soccer is the most popular sport in the world. People on all continents play it—some for fun and some for a living. Nicolette Iribarne, a Californian soccer player, has discovered a way to spread hope through soccer. He created a foundation to provide poor children with not only soccer balls but also a promising future.
Next time you play your favorite game or sport, think about why you enjoy it, what skills are needed, and whether these skills will help you in other aspects of your life.Through playing hide-and-seek, children are expected to learn to _____.
| A．be a team leader | B．act as a grown-up |
| C．obey the basic rules | D．predict possible danger |
The underlined part in Paragraph 2 most probably means that games can_____.
| A．describe life in an exciting way |
| B．turn real-life experiences into a play |
| C．change people’s views of sporting events |
| D．make learning life skills more interesting |
According to the passage, why is winning Olympic medals so encouraging?
| A．It proves the exceptional skills of the winners. |
| B．It inspires people’s deep love for the country. |
| C．It helps the country out of natural disasters. |
| D．It earns the winners fame and fortune. |
Iribarne’s goal of forming the foundation is to _______.
| A．bring fun to poor kids |
| B．provide soccer balls for children |
| C．give poor kids a chance for a better life |
| D．appeal to soccer players to help poor kids |
Nuclear power’s danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can’t detect them, sense them, without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated（辐射）and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.Which of the following statements is true?
| A．Nuclear radiation is just like common radio waves. |
| B．Nuclear radiation can cause cancer to human beings. |
| C．Nuclear radiation can be detected by human senses. |
| D．Nuclear radiation can be safe to human beings if its level is low. |
How can nuclear radiation kill an animal?
| A．By damaging its heart. | B．By killing a few cells. |
| C．By hitting any place in its body. | D．By killing many cells in important organs. |
If a human being is hit by nuclear radiation, he may _______.
| A．die of cancer after many years | B．die immediately |
| C．have a child who may be born weak | D．all of the above |
