We all know that if we want to keep our body in good shape we have to do physical exercise regularly as well as be careful with what we eat. What we tend to forget is that this goes for our eyes as well. Medical science confirms that a diet rich in carotenoids (类胡萝卜素) can help maintain good vision(维持好视力) and prevent against a number of eye diseases. Here's some advice about how to choose the right diet to keep your eyes healthy.
— Eat orange food. Fruits and vegetables with orange flesh are rich in carotenoids. In addition to carrots，oranges，pumpkins and sweet potatoes are also available. All of these contain high levels of carotenoids，which help to maintain good vision.
— Include dark green vegetables，such as spinach (菠菜) and broccoli (西兰花) in your diet, to act as natural sunglasses. Recent scientific studies have shown that these vegetables can help block (阻挡) the damaging UV radiation(紫外线辐射)from the sun's rays.
— Prevent some eye diseases with orange juice, yellow corn, whole milk, nuts and leafy vegetables. These foods are good sources of vitamins A, C, D and E. All of these are  necessary to good eye health.
— Increase your intake of omega­3 with some sea fish, and some other seafood. Omega­3 helps build cell walls and is especially beneficial to keeping eyes healthy .It also helps regulate the eye's internal pressure and helps the eye dry up excess fluid.

　Most people feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for yeas. Now researchers say there are three different types of loneliness.
　　The first kind of loneliness is temporary（暂时的）. This is the most common type. It usually disappears quickly and does not require any special attention. The second kind, situational loneliness, is a natural result of a particular situation-for example, family problem, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year.
　　The third kind of loneliness is the most severe. Unlike the second type, chronic（长期的）usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close to others. Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition.
Psychologists agree that one important factor in loneliness is a person's social contacts, e.g. friends, family members, co-workers, etc. we depend on various people for different reasons. For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share similar interests and activities. However, psychologists have found that, though lonely people may have many social contacts, they sometimes feel they should have more. They question their popularity.
　　Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease. While temporary and situational loneliness can be normal, healthy part of life, chronic loneliness can be a sad, and sometimes dangerous condition.
【小题1】How would you treat temporary loneliness according to the passage?

It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia (学术界) outweigh any financial considerations.

　　Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few prospects of a commercial return, and Lee’s is one of them.

　　The impact of a salary cut is probably less severe for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical (制药的) company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual opportunities.

　　Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition (转换) to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary team, manage budgets and negotiate contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. “Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who has spent all their time on a narrow research project.”
