阅读下面短文,根据其内容写一篇60词左右的内容概要。

    Bamboo is one of the world's most useful plants. For thousands of years, bamboo has been used in many different ways from food to medicine to clothing and in small ways as a building material.

    However, bamboo is not often used as a building material in the developed world. A professor at the University of Pittsburgh is trying to change that. The professor and his students are testing the strength of bamboo. They are testing how much pressure or weight it can take before breaking. Kent Harries is a professor at the University of Pittsburgh. Harries says that testing methods for bamboo need to be the same for all. They need to be standardized. Standardizing test methods for bamboo will help to bring the plant into common use. It will also give engineers and builders around the world a dependable standard.

    Harries says bamboo is strong in nature. The strength of at least three species of bamboo is similar to steel. Besides its strength, bamboo has other features that make it very useful in building. He says it is resilient (有弹性的), meaning it keeps its shape and strength even under pressure.

    Bamboo also grows quickly. Bamboo that is suitable for construction needs much less resources than wood. The harvest cycle of bamboo is about 3 years. Softwoods such as cedar, pine and spruce have a harvest cycle of about 10 years. And hardwoods that come from flowering plants such as oak and walnut need more than 30 years.

    Bamboo is widely used as food for pandas. It is also used for flooring and window covers. However, for building, bamboo is not used much outside is native growing area. This is mostly because of its round shape. But there are other reasons too. People think that bamboo is a low quality building material.

Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.

    An international team of researchers found employees who endure what is known as "abusive supervision" are more likely to behave poorly on purpose by messing up tasks, arriving late, taking long breaks and putting in minimal effort.

    The authors of the study, published in the Journal of Management, sought to answer why horrible bosses make employees less willing to show what is known as organizational citizenship behavior (OCB), or commitment to the company outside of their contractual obligations. That could include helping colleagues or volunteering for unusual work hours. They also assessed its effect on a worker's tendency to harm the organization, by displaying counterproductive (反作用的) work behavior (CWB).

    To find out more, and uncover which negative outcome bullying (欺凌) behavior is more likely to cause, researchers from Southwestern University of Finance and Economics in China, Renmin University of China and Swinburne University of Technology in Australia cooperated and analyzed 427 existing studies. They found workers acted out either because they felt they were being treated unfairly in the workplace, or felt stressed and this affected their ability to perform as expected. An employee who felt they were a victim of injustice tended more towards reluctance to show OCB. Stressed workers, meanwhile, were more associated with CWB.

    Employers who worried supervisors are affecting productivity can take steps to ease issues by regularly training managers, introducing policies which cope with workplace injustices and helping workers to deal with stress.

    This is not the first study to suggest unkind practices can affect the well-being of workers. The paper follows a study published in the European Heart Journal last year, which showed employees who suffer bullying are more likely to develop heart diseases than those who aren't. Bullying and violence are common at workplaces and those exposed to these stressors are at higher risk.

阅读下面短文, 根据其内容写一篇60词左右的内容概要。

    Tired of all the pushing in supermarkets? Fed up with waiting in endless lines to pay for what you have bought? Angry at wasting time in traffic jams only to find no parking spaces when you eventually arrive at the store? If this is you, then online shopping is the answer to your dreams of trouble-free shopping, or is it?

    Online shopping brings its own challenges. Here are a few things to bear in mind when browsing (浏览) various websites. The claim (声称) made by online sites is that shopping online is a safe and secure way to make purchases. The evidence challenges this. In any case, you only have to be the victim of fraud (欺骗) once to experience all the problems that come with this form of deceiving. Use only sites that have a trusted history and an excellent reputation.

    Another problem is that the appearance of items in reality is often quite different from what you see on your computer screen. This might not be a problem if you are buying washing powder but could be a major disappointment when that beautiful blue dress you ordered turns up in green. Also, product descriptions are sometimes simply untrue! Perhaps the wisest plan is to purchase items where design and colour are not essential to customer satisfaction.

    Some even argue that online shopping indirectly contributes to global warming. Yes, your car can stay parked but how are online goods delivered? Often by some large vans pouring out carbon monoxide(一氧化碳) and adding to our already desperate traffic problems. You are also by now becoming increasingly irritated(烦恼的) by the fact that the delivery is late and you have wasted the leave from work to receive it!

 Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.

For thousands of years, Chinese people have valued the large family with three, four, or even five generations living under the same roof. That's what we call an extended family. Now it is changing. Compared to extended families. nuclear families which involve only two generations living together are becoming the trend. Apart from family size, these families are also featured by reduced dependence on the last generation. Young people are able to make decisions on their own and children are less likely to be brought up by their grandparents.

The reason for the tendency of nuclear families can be reflected as follows. It's a time when young people think highly of individual freedom. Young people like to have personal space that won't be disturbed by the old generations. In this way, they are more likely to avoid conflicts caused by different living habits from their parents.

It's also a time when social welfare institutions are highly advanced for old people to lead a comfortable life . Senior citizens can live together in some nursing homes and be taken good care of by specialized nursing workers, which may base young people's heavy burden of attending their aging parents.

However, the problem concerning attending to children turns up as the number of nuclear families increases. Young people are busy with their work and spend less time with their children. As a result, lacking enough care both from their parents and grandparents during their growth, children may develop mental illnesses like loneliness and depression. Many young people, therefore, hire babysitters to look after and keep company with their children, which adds a financial burden to them.

Facing the problem above, young people can seek help from old generations, communities and government. Old generations are welcomed to take care of their grandchildren, especially when young people are asked to work overtime. Communities ought to organize some volunteers to look after unattended kids. And government can set up special loads for young people to relieve their financial problem. With the joint efforts, nuclear families are expected to fit in well with the development of the society.
