Why companies look for employees with language skills E Damming the Red Sea could solve the growing energy demands of millions of people in the Middle East and reduce some of the region's tensions related to oil supplies through hydroelectricpower. Equally, such a large engineering project may cause untold ecological harm and make countless people leave their homes. Present technology allows us to shape the earth on a relatively large scale and to control lakes for hydroelectric power generation. In the near future, however, it might be possible to build dams large enough to separate a body of water as large as the Red Sea, from the world oceans. A similar large-scale engineering project is already planned for the Strait of Hormuz at the entrance of the Persian Gulf. This seawater barrier will use the evaporativecycle and inflow of seawater to produce vast quantities of electricity. Geochemical engineer Reolof Dirk Schuiling suggests that a dam across the Bab-al-Mandabcould be used to stop the inflow of seawater into the highly evaporative Red Sea with the potential of producing 50 gigawattsof power. By comparison, the Palo Verde nuclear power plant, the largest nuclear station in the US, has an output of just 3.2 gigawatts. "Such a project will greatly affect the region's economy, political situation and ecology, and their effects may be felt well beyond the physical and political limits of the project," says Schuiling. Schuiling points out that the cost and time involved in creating such a hydroelectric project are way beyond normal economical considerations. It's certain that such a large engineering project will cause great destruction of existing ecologies. However, it will also provide enormous reductions in greenhouse gas emissionsas well as offering a workable, sustainable alternative to fossil fuels for future generations: Researchers point out that the precautionaryprinciple cannot be applied in making a decision regarding the damming of the Red Sea. If the countries around the Red Sea decide in favor of the macro-project, it’s their responsibility to limit the negative consequences as much as possible.

       Learning another language isn't easy, but most people can learn a second language well if they’re willing to put in the necessary time. Here are some practical suggestions for studying effectively, overcoming anxiety, and learning the grammar and skills necessary for success in foreign language classes.

Study every day

Language learning is cumulative: you cannot put it off until the weekend. Study one or two hours for every class hour if you want a good mark.

Distribute your study time in 15 to 30 minutes period throughout the day

Study a different task each time: vocabulary now, grammar next, etc. Get an overview during the first half hour: spend 10 minutes reviewing dialog, 10 minutes learning new vocabulary, 10 minutes learning new grammar... So you'll at least have looked at it all. About 80~of your study time should be spent on recitation or practice.

Attend and participate in every class—even if you aren't well prepared

Class time is your best opportunity to practice, learn the grammar and vocabulary outside of class in order to make full use of the class time. Spend a few minutes "warming up" before each class by speaking or reading the language.

Make yourself comfortable in the classroom

Get to know your classmates, so you'll feel you’re among friends. Visit your teacher during office hours to get aquainted(熟悉的):explain your goals and fears about the course to your teacher.

Learn grammar if you don't already know it

Grammar is the skeleton(骨架) and the basic structure of a language, and you must learn it.

Practice for tests by doing what you'll have to do on the test

If the test will require you to write, then study by writing--including spelling and accents. If you're asked to listen, practice listening. Ask for practice questions and make up your own test questions. Try to invent changes on patterns and forms. Over learning is also required in tests preparation:study beyond the paints of recognition to mastery.

Develop a good attitude

Have a clear personal reason for taking the class. Set personal goals for what you want to learn. Leave perfectionism at the door; give yourself permission to make mistakes and learn from them.

16. What does the underlined word "cumulative" in Paragraph 2 probably mean?

    A. process of gaining knowledge or skill by doing and seeing things

    B. having to do with comparison

    C. having ability to do what is needed

    D. increasing in amount by one addition after another

17. A good learner is one who ________ according to the passage.

    A. never permits himself to make mistakes

    B. can learn something from the mistakes he makes

    C. follows the goals that other persons set for themselves

    D. can get to know his classmates and doesn't take his teachers' advice

18. What would be the best title for the passage?

   A. Tips on studying a foreign language. 

   B. Advice on how to learn grammar.

   C. Suggestions for studying vocabulary effectively.     

   D. How to make yourself comfortable in the classroom.

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