We all know that global warming is caused by greenhouse gases, largely carbon dioxide, which is given out by everything ranging from home appliances(电器) and cars to the heating and lighting systems of office buildings. But since we don’t see the gas, most of us simply shake our heads and then continue with our bad habits. Now, researchers at Arizona State University are trying to change that.
Directed by associate professor Kevin Gurney, the Hestia Project’s main goal is to make something that is currently intangible (无形的) into something a little more tangible, by allowing all of us to visually see how much each and every one of us is “contributing” to global warming.
In order to obtain a complete picture of the city’s environment, the team begins by collecting data from all different sources. Then, using special software they divide the emissions (排放) into three categories — commercial entities (实体) (office buildings and industrial plants), households and vehicles. This is the stage where things start to get really interesting. That’s because instead of showing all this information using graphs that we all instantly lose interest in, they create a visual “film” that shows not only the carbon emitted by each entity, but also the exact location it is coming from and the amount, which varies depending on the time of day or season. For example, the car emissions during rush hour are the highest, as is the case for commercial buildings during the day, especially during winter months when the heating is on.
Kevin knows that some of the data shown may start a blame game among the residents (居民) of the city. However, he is hoping that the people will go beyond that and instead use it to make changes in their daily lives. According to the text, most people ignore the problem of greenhouse gases mainly because _____.
| A．the problem is not very serious |
| B．bad living habits are hard to change |
| C．greenhouse gases can’t be seen |
| D．they think they have done nothing wrong |
With the efforts of Kevin’s team, people can _____.
| A．see a film about the effects of greenhouse gases |
| B．study methods of cutting greenhouse gases |
| C．know a certain place’s emission at different times |
| D．get information on emissions with various graphs |
By saying “some of the data shown may start a blame game among the residents of the city”, the author means that _____.
| A．Kevin’s team may get criticized |
| B．the Hestia Project may be treated as a game |
| C．residents may feel guilty of their bad behavior |
| D．people may accuse each other of carbon emissions |
What’s the purpose of the text?
| A．To introduce a research project. |
| B．To give advice on cutting emissions. |
| C．To show the harm of carbon emissions. |
| D．To call on people to protect the environment. |
“An apple a day keeps the doctor away.” Similarly, if we drink a little more water ever day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fibre, without giving us too much fat and sugar. But why is water important?
The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems stars as a result of dehydration—a lack(缺少) of water in the body. Most people are dehydrated at least some of time, although they probably don’t know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.
These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water.
There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.We need _____for a healthy diet.
| A．fibre | B．food | C．water | D．Water and different foods |
From the text, we know water can carry_________.
| A．energy and fibre in our bodies | B．fruit, vegetables and fish in our bodies |

| B．they think they are thirsty and eat less |
| C．water has no calories |
| D．it makes them hungry |
Which of the following isn’t mentioned in the passage?
| A．Fruit provides us with energy and fibre. |
| B．Some healthy problems start because of a lack of water. |
| C．Drinking more water may stop people from overeating. |

Sometimes children do not do what their parents tell them to do. When this happens, a parent tries to help the child to do the right thing. When this does not work, the parent usually punishes the child.
There are many things that a parent can do. One thing that people have done is to spank (打屁股) the child. When a parent spanks a child, they will use their hand or a hard object to strike them on their bottom. This is meant to show the child that they have done something wrong
everything and not try other ways to get the child to do the right thing。
Many parents are not sure of what to do instead of spanking. Some people think that their religion（宗教）tells them that spanking is okay. Some think that the law lets them do it. The courts (法院) say that parents have the right to teach their children how to behave.
Other things should be tried before a parent decides to spank a child. Telling the child exactly what is wanted from them can be one thing. Giving a child more than one choice is another thing that can be tried. Getting down to the child’s level and taking a more child-friendly approach (方法) can help as well.According to the passage, when children do something wrong, one thing that parents usually do to punish them is to ________.

Australia has passed regulations that will enable more international students to further their education in the country.
The new measures were released by the Australian Department of Tertiary Education, Skills, Jobs and Workplace Relations in September and will take effect in mid-2012.
As a result, the student visa application process for overseas students has been simplified, and the deposit (押金) required to study in Australia has been reduced. Language requirements for overseas students have also been eased.
Also, overseas students receiving a higher education in Australia will be granted a working visa lasting from two to four years after graduation, as long as they meet the basic IELTS requirement.
"This change will definitely make Australia a more attractive destination for Chinese students planning to study overseas," says Wang Lan, a consultant from Education International Cooperation Group (EIC), a Beijing-based company that provides services to students wishing to study overseas.
However, in the past few years, many of Wang's student clients (客户) could not start studies in Australia because they did not meet the language requirements, visa processing took a long time and deposit regulations were tough. The change in policy is good news for the parents of students wishing to study in Australia, Wang says.
A 22-year-old female student surnamed Li, in Beijing, who is planning to do her postgraduate studies in Australia, learned about the policy change several weeks ago.
"According to the previous deposit requirement for my student visa, my family was required to put down 550,000 yuan ($86,850). Now we only need to prepare 410,000 yuan. This is a relief for my parents," Li says.
She also says that the two to four years working visa makes her feel much clearer about her study plans.
"I believe several years of working experience abroad will strengthen my competitiveness when I return to China," she says.
Gaining a competitive advantage is the major reason for Chinese students to study abroad, according to the report by EIC.What's the main idea of the passage?
