Telling the readers that gene technology will not benefit people D. Explaining that gene technology will also do harm to the humanity E The European capital cities, Berlin and London, running the third and the fourth richest economies in the world, both produce about a metric ton of rubbish for each household per year. But when it comes to disposing of their citizens’ waste, the comfortable similarities end. London, and Britain as a whole, is in the middle of a waste crisis. Today, the environment secretary, Margaret Beckett, is presiding over a waste summit to try to find out why the UK is not going to reach its 25% recycling and composting target by 2005; currently, it is managing 11% By comparison, Berlin and Germany know exactly where they are going. Although Berlin has been the capital for less than a decade, and has had east and west to unite, it has already reached 40% recycling. The city has one ambition: to have no rubbish to dump or burn in 20 year’s time. So far, the city has not decided quite how, but it is developing new technologies and moving steadily in the right direction. London, by comparison, has a chaotic system. The 33 boroughs all have different recycling systems. Ken Livingstone, who since taking office as mayor has published a brand-new waste management strategy for the capital, is responsible for sorting out this hotch potch. One of the most contentious issues both for London and Berlin is incineration, with both cities burning a large proportion of their waste---London 20% and Berlin 32% Here again Berlin has made decisions and London is uncertain. Berlin has a state of the art incinerator in the 1970s and upgraded constantly until in the 1990s it is impossible to detect any emissions but warm gases. The city has abandoned plans to build another and instead wants to make the existing one redundant by reducing the waste so there is none to burn London boroughs have plans to increase the size of the incinerator at Edmonton and there are plans to build more elsewhere. But Livingstone is resisting and the government is already rethinking its current energy from waste policy. Samantha Heath, the chair of Greater London Authority’s environment committee, wants to invest in the market for recycled goods so there is somewhere for the material to go and a prospect of selling it, or at least disposing of it for less than the price of incineration or landfill Ingolf Rank, spokesman for Berlin’s City Cleaning company has some advice: “The first task is to get the public on your side. Each household has to pay 40 pounds every three months to dispose of its rubbish. In future, the less they create, the more they recycle and compost, the less they will have to pay, he says. Each house in Berlin has a series of different coloured bins for refuse so glass, paper and plastics can be separated for recycling. This allows 800 000 tonnes of rubbish a year to be turned back into useful items. But Berlin has ideas that have not ever been heard of in London. For example, at this time of year, thousands of trees that line Berlin’s streets shed their leaves. Rather than put these leaves into general rubbish and add to the problems of disposal, they are collected up in large vacuum cleaners and turned into garden compost. Most of London has no composting service at all. Another system that stops material even being called rubbish is a collection service for second-hand furniture and electrical goods less than seven years old. Each offering is inspected, taken to a central shop, and sold at low cost to poorer people. It saves a lot of material being dumped. Not all goes according to plan in Berlin, however. Rank says that people dump waste in the streets, like mattresses, old furniture or just general rubbish cost the city 2.8 million pounds a year. One problem the city has tried to solve but failed, is the excreta of 150 000 dogs. Rank says it is the owners’ responsibility to clean up after their pets but police who tried enforce the law were “sometimes bitten , insulted by the owners and even beaten up. As a result we still have to clean up 40 tonnes of droppings every day. Nobody is happy about that. 【查看更多】

Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.

The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(寿命) can be prolonged. www.zxxk.com

Gene technology can help people to give birth to healthy and clever children. Some families, with the English imperial family being a good example, have hereditary(遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it, and a healthy child will be born.

Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the government must take care to control gene technology.

1.What does “these two killers” in the second paragraph refer to?

A. Gene technology and another treatment of the two diseases.

B. The two murderers who killed the cloned baby.

C. The two diseases of cancer and heart disease.

D. Hereditary diseases and cancer.

2.What’s the main idea of the third paragraph?

A. How gene technology can be applied in the field of treating hereditary diseases.

B. Gene technology can be used to clone human babies.

C. Gene technology can help people to give birth to a baby.

D. Gene technology can help the English imperial family out.

3.In what way gene technology can help to treat hereditary diseases?

A. Using gene technology, people with hereditary diseases can have more living days.

B. Using gene technology, the scientist finds the wrong gene and corrects it.

C. Using gene technology, human babies can be cloned.

D. Doctors can cure cancer and heart disease with the help of gene technology.

4.What is the main purpose of writing this passage?

A. Expressing the writer’s idea that gene technology will benefit people.

B. Telling people the disadvantages of gene technology.

C. Telling the readers that gene technology will not benefit people.

D. Explaining that gene technology will also do harm to the humanity.
