“Mars Orbit Express” is a space probe (探测器). It was sent towards Mars by American scientists on August 12th,2005. Its tasks are to study Mars’ atmosphere and return photos to Earth. But before that “Mars Orbit Express” must travel about 100 hundred million kilometers and seven months. It reached Mars’ orbit(轨道)in March,2006.

But while Earth supports millions of lives,Mars becomes bad. “Earth easily could have turned out like that.” said an scientist, “It is important for us to find out why and Mars Orbit Express’ should do that.” “Mars Orbit Express” also would help scientists to learn what might happen to Earth in the future. “Mars Orbit Express” would work for about four years.

Smoking in indoor public places including public working places, public transport vehicles and some other special outdoor working places has been banned(禁止)in China since January 2011.Let’s look at the following advantages of banning smoking.
First, banning smoking will not only help in saving smokers from health problems and diseases, but will also be good for passive(被动)smokers. When the smoker is smoking in a restaurant, the people around him are sure to breathe in the smoke and suffer from the diseases an active smoker gets. If smoking is banned, spread of these diseases can be controlled.
Next, banning smoking will put stress on smokers to give up. Since a smoker is prevented from smoking, he will learn how to live without smoking for long hours. When a smoker doesn’t smell or see anybody around him smoking, it might reduce his wish to smoke too. As a result, people have to give up smoking.
Smoking in public places influences non-smokers to start smoking, especially adolescents. When teens see people around them smoking, they will follow them easily. Thus the number of teen smokers will increase. Also asthma(哮喘)and other problems are often seen in children living around smokers. So if it is banned, these places will become safe for children and teenagers.
Looking from the economic point of view, smoking should be banned to increase work productivity(生产率).Employees(雇员)who smoke usually take breaks to smoke while working. So the number of hours they put in their work is smaller.
If you see from the environment point of view, smoking should be banned. Smoking causes air pollution. If it is banned, it will help keep the environment from getting worse.
小题1:________doesn’t belong to a non-smoking place.
A.A field | B.A hospital | C.A library | D.A restaurant |
A.banning smoking is good for restaurants |
B.banning smoking is good for non-smokers |
C.banning smoking is good for spread of diseases |
D.banning smoking is good for active smokers and passive smokers |
A.Two. | B.Four. | C.Five. | D.Six. |
A.men | B.women | C.adults | D.teenagers |
A.If smoking is banned, work productivity will increase. |
B.If smoking is banned, the number of teen smokers will be larger. |
C.If smoking is banned, it will make the environment become better. |
D.If smoking is banned, smokers will learn how to live without smoking. |

The first Earth Hour was held in 2007 in Sydney, Australia when 2.2 million individuals(个体) and more than two thousand businesses turned their lights off for one hour to take a stand against climate change. Only a year later Earth Hour had grown into a global event with more than 50 million people across 35 countries and territories(行政区)participating(参加). Global landmarks such as the Sydney Harbour Bridge, CN Tower in Toronto, Golden Gate Bridge in San Francisco, and Rome’s Colosseum, all stood in darkness, as symbols of hope for a cause that grows more urgent(紧急) by the hour. In March 2009, millions of people took part in the third Earth Hour. Over 4000 cities in 88 countries and territories have promised their official support for the event.

The event is organized by the World Wide Fund for Nature, also known as the WWF. The organizers say climate change is one of the greatest threats(威胁) facing wildlife and nature.

Now people are all joining together in a global effort to show that it’s possible to work on global warming. Earth Hour has brought about some new changes to our lives. People join in activities such as candle-lit dinners and star-gazing parties as a response to the call for "going dark".
This year , Earth Hour is asking people to take the next step and go beyond one hour.
