Electronic waste, or e-waste, refers to electronic products that are no longer usable. This can include TVs, cell phones and computers and other office electronics, electronic toys and videos machines. Today, the average turnover（更换）rate for a computer in the United States is every two years, according to the environmental group, Greenpeace.

The group's Dai Yun says e-waste is a global problem. "The electronic industry is one of the fastest growing industries in the world. The high speed of growth in this industry means more and more electronic products are being wasted and thrown away. If no one decides to retrieve the old products and process them properly, the electronic waste will sweep over the earth like the huge wave behind me and pollute the Earth seriously."

Greenpeace works out that 20 to 50 million tons of e-waste are produced globally each year. The components（部件）in many electronic products contain harmful chemicals that pollute ground water and the environment.

At present , the U.S. has no federal law for the disposal (处理) of e-waste although a few states have e-waste recycling programs in place, but there is no law. The U.S. exports much of its e-waste to third world countries, such as India and China, where workers took apart computers for valuable parts, hoping to sell them for money. But harmful wastes expert, Dr. Bakul Rao, says that's a dangerous practice. "From now on, the recyclers are not very educated. All they know is they can retrieve copper or gold out of it. So, the easiest way to do that is leach (过滤) it out in an acid or burn it off to retrieve it. So, that's where they don't know how to deal with it, neither do they have any health systems in place. So, their exposure is more."

Which of the following is most likely not to be a form of e-waste?

A. A mobile phone B. A radio C. An e-bike D. A table

What does the underlined word "retrieve" (paragraph 2) probably mean?

A. look into B. take apart C. get back D. throw away

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’s 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.

Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial(皇帝的) 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. Scientists 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(生产) 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 governments must take care to control gene technology.

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.

What’s the main idea of the third paragraph?

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

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

C. How gene technology can be used to treat hereditary diseases.

D. Gene technology can solve all the problems of the English imperial family.

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

A. Gene technology helps people with hereditary diseases to live longer.

B. Using gene technology, scientists find the wrong gene and correct it.

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

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

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 advantages and 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.
