Although cigarette butts, are small, they are bad for the environment. Over 1,600 billion cigarette are smoked each year in China and large quantities of the butts are thrown away. Worldwide, about 4. 5 trillion butts are littered every year. Apart from the fact that butts spoil the beauty of the environment, they contain some very toxic chemicals. These find their way into the water supply where they decrease the quality of the water and endanger plants and animals that live there. So, if people have to smoke, they shouldn"t throw away the butts but put them in the rubbish bin instead.
Plastic bags are another common form of litter that is a danger to the environment. There areseveral reasons for this. They are made from oil and gas, which are non—renewable resources. If they are not recycled, these resources are lost to us. In China, 2 billion plastic bags are used every day. An enormous number of these become litter. This is a huge problem because they last from 20 to 1,000 years in the environment. They float easily in the air and water and travel long distances. They find their way to rivers, parks, beaches and oceans. Plastic bags kill up to one million seabirds, 100, 000 sea mammals and countless fish each year worldwide. It is up to people not to let plastic bags become litter. It would be better if they used fewer and recycled them.
Cleaning up your cigarette butts and plastic bags would improve the environment. And we would know that we were doing something to look after our planet. However, I believe the best solution would be not to smoke or use plastic bags at all.

举一反三
ill in the name of equality，want only to destroy it．Any society which is interested in equality of opportunity and standards of achievement must regularly test its pupils．The standards may be changed—no examination is perfect--but to have no external(外部的)tests or examinations would mean the end of equality and of standards．There are groups of people who oppose this view and who do not believe either in external examinations or in any contr schools or on teachers.This would mean that everything would depend on luck every pupll would depend on the efficiency(效率)，the ideal and the purpose of teacher．
Without external examinations， employers will 1ook for employees from highly respected schools and from families known to them--a form of favoritism will replace equality．At the moment，the bright child from an ill—respected schoo1 can show certificates(证书)to prove he or she is suitable for a job，while the lack of a certificate shows the unsuitability of a dull child attanding a well—respected schoo1.This defence of excellence and opportunity would disappear if external examinations were taken away，and the bright child from a poor family would be a prisoner of his or her school’s fame(名誉)，unable to compete for employment with the child from the favored schoo1．
The opponents(对手)of the examination system suggest that examinations are an evil force because they show differences between pupils．According to these people，there must be no special，different，academic class． They have even suggested that there should be no form of difference in sport or any other area：all jobs or posts should be filled by unsystematic selection．The selection would be made by people who themselves are probably selected by some computer．

| A．bright children also need certificates to get satisfying jobs. |
| B．Pooor children with certificates are favored in job markets. |
| C．Children attending ordinary schools achieve great success. |
| D．children from well-respected schools tend to have good jobs. |
| A．Children’s job opportunity would be affected by their school reputation. |
| B．Schools for bright children would lose their reputation |
| C．There would be more opportunities and excellence. |
| D．Children from poor families would be able to change their schools. |
tem will agree that _____.| A．Computers should be selected to take over many jobs. |
| B．Special classed are necessary to keep the school standards. |
| C．Jobs should not be assigned by systematic selection. |
| D．Schools with academic subjects should be abolished. |
A. schools and certificates B opportunity and employment
C. examinations and equality D. standards and reputation

ion all over the world because we can easily take it to go everywhere. Also, we do not need to worry about danger on a long-distance trip. Now, we have comfortable buses in London. I would like to describe how comfortable they are. First, the number of seats on a bus has been reduced from 44 to 19. The reason why the number of seats is now 19 is that the seats have been changed to big and comfortable sofas.Originally, they chang
ed the normal seats to airplane seats and took out ten seats from the buses. However, every customer wanted to have a more comfortable seat on the bus when they went on long-distance trips, so they changed them to sofas. Also, the owners of the bus companies wanted to make more money, so they tr
ied to meet the passengers’ needs. They changed the airplane seats to sofas, so the number of seats is now 19.As the new buses appear, the prices go up, too. The owners have many ideas, which you have probably never thought about before. Now they have bus attendants who serve water, snacks, newspapers, and towels.
Also, you can change the direction and the height of the sofa to make yourself more comfortable, and there is a service bell on each sofa. Moreover, some companies show movies on the buses. In addition, when you go on a long-distance trip, they have luxurious(豪华的) buses that have an LCD screen on each seat. That is not the only surprising thing on the bus. They also have different TV channels, movie channels, and seventy TV games for killing time while you are on the bus.

The blog is one form of communication that increased in popularity. Through these personal websites, people can share their lives, ideas and opinions on the Internet. People of all ages have their own blogs. For young people, they are a way to show their writing and other forms of self-expression. Blogs also connect people with other people who have the same interests. For example, teachers use blogs to share ideas with other teachers’, as well as experiences and concerns about their work.
YouTube is another Internet site that became more popular last year. This website lets anyone create, share and watch short videos. These include videos of people singing or dancing, or animals doing funny things. Three young men created YouTube almost two years ago as a personal video sharing service. They recently sold it to Google for more than one and a half billion dollars.
Games and entertainment also became a l
arger part of the Internet last year. One Internet social site is called Second Life. It is an online world in which computer u
sers create a new self and live a different life. They get married, build homes, operate businesses, buy and sell goods, work, play and attend school. People also take part in fantasy sports leagues with the help of the Internet. A fantasy sport is a game in which each member of a group acts as the owner of a team. Each owner creates a team of real-life professional players to compete against other teams in the league. More than fifteen million American adults play fantasy sports. The industry earns more than one billion dollars each year from publications, memberships and other costs.

ting oceans, killing wildlife and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a solution.The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has-discovered a way to make plastic bags degrade(降解) in as few as 3 months, a finding that won him first prize at the Canada Wide Science Fair, a ＄10,000 prize, a ＄20,000 scholarship, and a chance to revolutionize a major environmental issue.
Burd’s strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.
With this goal in mind, he grounded plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.
The inputs are cheap, maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.
“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” Said Daniel Burd.

acteria to .| A．make the live bacteria work better | B．test how effective his method was |
| C．know which bacteria worked faster | D．control the temperature in the process |
Maintaining the required temperature takes little energy because .
| A．plastics can get hot easily | B．microbes can produce heat themselves |
| C．much carbon dioxide is produced | D．the temperature can be controlled |
| A．his school textbook | B．the failure of researchers |
| C．his everyday work | D．the practice of other people |
