We are all busy talking about and using the Internet, but how many of us know the history of the Internet?

Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way, computer network system would keep on working all the time.

At first the Internet was only used by the government, but in the early 1970s, universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers had become cheaper and easier to use. Scientists had also developed software that made “surfing” the Internet more convenient.

Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students.

The Internet has now become one of the most important parts of people’s life.

We all know that water is tasteless. But it happens from time to time: you pick up the bottle of water you didn’t finish yesterday, and it tastes strange. Most often, you tend to drop the bottle in the trash bin, believing that the water has gone bad. But is it true?

According to Time, of course not, taste has little to do with quality of water.

According to Time, when water is exposed to the air for 12 hours, carbon dioxide interacts with the H2O in the water, and the pH value lowers slightly. As a result, the water has a different taste.

“But it’s most likely safe to drink,” Norwegian expert Truls Krogh told Science Nordic. “If the water is covered and of good quality to start with, in principle it can last a thousand years. That’s because when water is fresh, it contains little organic matter. As long as water is held in clean glasses or bottles, no pollutants will enter it to harm our health.”

People in countries like the US, the UK and Australia usually drink tap water. According to Time, if tap water is drunk within six months, the chlorine (氯气) in the water will be enough to kill any bacteria and keep it safe to drink.

However, there are also some exceptions. If you accidentally put your fingers into water or store water in unclean containers day after day, microorganism (微生物) will enter the water.

With the help of surrounding temperature, and sunlight streaming through windows, these microorganisms multiply quickly. Sooner or later, the water will be in the charge of the unfriendly bacteria. And if you drink the water too often, then you’re more likely to be ill.

And what about water in plastic bottles? Heat and plastic are a bad combination, US researcher Kellogg Schwab stresses. When plastic bottles are used at high temperatures, they produce a chemical called BPA. BPA is something that affects hormones (荷尔蒙) and research has tentatively linked it to “several health damage, including heart disease and cancer”, Time reported.

Schwab suggests replacing disposable (一次性的) plastic bottles with the refillable containers made of metal or glass to deal with BPA.

1.The purpose of the first paragraph is to ________________.

A. show an example B. draw a conclusion

C. analyze a phenomenon D. introduce a topic

2.Which of the following may Truls Krogh agree?

A. If the water tastes different, we shouldn’t drink it.

B. The water held in a clean container is likely safe to drink.

C. Although kept fresh, water may still have much organic matter.

D. Covered water can last for a thousand years.

3.What can we infer from the passage?

A. BPA does little harm to our health.

B. Tap water is always safe to drink.

C. Microorganisms are easy to produce in the heat.

D. Disposable plastic bottles have been banned already.

4.What can be the best title of the passage?

A. Why Water is Tasteless B. How to Get Clean Water

C. Does Water Really Go Bad? D. Learn to Protect Water

Benefits of green spaces

We all know the value of taking a walk in the fresh spring weather. It allows your mind to relax and forget about the problems in everyday life. Studies have commonly shown the benefits of being around green spaces, including gardens, urban parks and forests.

But did you know that being in contact with these natural surroundings during childhood could positively impact your mental health as an adult?

A study by the Barcelona Institute for Global Health (ISGlobal) surveyed 3,600 people from all over Europe, including Spain, the Netherlands, Lithuania and the UK.

The all-adult study gave participants a questionnaire on how frequently they used natural spaces during childhood — for example, playing in a garden, riding a bike at the park or hiking in a forest. They were also asked about the importance they put on using such places.

Volunteers were then given a psychological test, which included a variety of questionnaires and problem-solving activities, to analyze their nervousness and feelings of depression (抑郁) within a four-week period.

The results consistently showed that the people who were more exposed to natural spaces had higher mental health scores compared to those with lower childhood exposure — as did those who attached higher importance to using green spaces.

The study’s coordinator (协调员), Wilma Zijlema, wrote that the results “show the importance of childhood exposure to natural spaces for the development of a nature-appreciating attitude and a healthy psychological state in adulthood”. She also stressed the importance of “recognizing the implications (含义) of growing up in environments with limited opportunities for exposure to nature”.

According to the study, 73 percent of Europe’s population only has limited access to natural spaces. Mark Nieuwenhuijsen, director of ISGlobal’s Urban Planning, said that “Many children in Europe lead an indoor lifestyle … so we call on policymakers to improve the availability (可得性) of natural spaces for children.”

While this study was based in Europe, a lack of green space can affect anyone, anywhere. So remember to make time to immerse yourself in nature, as your mental health is just as important as the physical one.

1.What was the purpose of the ISGlobal’s walking study?

A.To examine the advantages of taking a walk.

B.To understand the mental health problems of children.

C.To see how childhood experiences shape adult life.

D.To study the influence of childhood exposure to natural spaces.

2.What do we know about the study?

A.The participants included both children and adults.

B.The participants were from all over the world.

C.It focused on the participants’ physical health state.

D.It consisted of a questionnaire and a psychological test.

3.What do Paragraphs 7-8 mainly talk about?

A.The value of the study. B.The results of the study.

C.The method of the study. D.The process of the study.

4.What does the underlined word “immerse” in the last paragraph probably mean?

A.Protect against something. B.Understand something.

C.Lose oneself in something. D.Imagine doing something.

We all need physical exercise. Exercise uses up food we eat and keeps the body full of energy. It works our muscles and makes our heart work hard so as to send blood to our muscles. So, exercise makes our heart and muscles strong. Exercise also makes us feel refreshed. If you exercise a couple of times a week, you will stay happy and healthy.

Some Western countries, such as the United States, have problems with exercise. In the US, many people don’t have enough exercise because it is hard for them. People have to work from dawn till dusk, so they don’t have time to take exercise. They work in office buildings sitting in chairs all day long in front of computers. They cannot get much exercise sitting at desk passively.

Some Westerners can get exercise walking from their homes to work. However, the majority of the people cannot do this. It is too far from their homes to their offices. They have no choice but to drive to work. In fact, some have to drive one or two hours to their offices. This has an unfavourable effect on them in two ways. First, these people don’t have a chance to exercise because they are sitting in their cars for two to four hours each day. Second, driving is challenging especially in rush hours and calls for too much attention. It makes a person worn out. So, when these people arrive home at night, they don’t have the desire to take exercise after work.

Today, many people in the West are overweight, which causes health problems for them. Doctors say exercise can help people both lose weight and improve their health. So many people are trying to get more exercise. But it takes time to change, and when people don’t see a difference right away, they will lose heart and stop exercising.

1.List two of the benefits we can get from physical exercise. (No more than 15 words)

2.Why can’t people in the US take enough exercise? (No more than 10 words)

3.The underlined word in paragraph 3 probably means __________. (1 word)
