1、Mobile Phones
Mobile phones should carry a label if they proved to be a dangerous source of radiation, according to Robert Bell, a scientist. And no more mobile phone transmitter towers should be build until the long-term health effects of the electromagnetic radiation they emit is scientifically evaluated, he said. "Nobody's going to drop dead overnight but we should be asking for more scientific information," Robert Bell said at a conference on the health effects of low-level radiation. “If mobile phones are found to be dangerous, they should carry a warning label until proper shields can be devised,” he said.
A report widely circulated among the public says that up to now scientists do not really know enough to guarantee there are no ill effects on humans from electromagnetic radiation. According to Robert Bell, there are 3.3 million mobile phones in Australia alone and they are increasing by 2,000 a day. By the year 2000 it is estimated that Australia will have 8 million mobile phones: nearly one for every two people.
As well, there are 2,000 transmitter towers around Australia, many in high density residential areas. For example, Telstra, Optus and Videophone build their towers where it is geographically suitable to them and disregard the need of the community. The electromagnetic radiation emitted from these towers may have already produced some harmful effects on the health of the residents nearby.
Robert Bell suggests that until more research is completed the Government should ban construction of phone towers from within a 500 metre radius of school grounds, child care centres, hospitals, sports playing fields and residential areas with a high percentage of children. He says there is emerging evidence that children absorb low-level radiation at a rate more than three times that of adults. He adds that there is also evidence that if cancer sufferers are subjected to electromagnetic waves the growth rate of the disease accelerates.
____ According to Robert Bell, it is reasonable for the major telephone companies to fund it. Besides, he also urges the Government to set up a wide ranging inquiry in to possible health effects.

2、Smallpox virus
It's now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US and one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?
In reality, of course, it was naive to imagine that everyone would let go of such a potential weapon. Undoubtedly several nations still have ____ vials. And the last “official” stocks of live virus bred mistrust of the US and Russia, for no obvious gain.
Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines. So one again there's a good reason to keep the virus—just in case the disease puts in a reappearance.
How do we deal with the mistrust of the US and Russia? Simple. Keep the virus under international auspices in a well-guarded UN laboratory that's open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn't mean the idea is wrong. If the virus is useful, then let's make it the servant of all humanity—not just a part of it.
【单选题】

A.much

B.more

C.most

D.a?few

正确答案:D

答案解析:vials是复数，much不合适。另外，本句和上文都没有比较的意思，因此more和most也都不合适。故D为正确答案。

4、Reduce Packaging
Pressure increased recently on British supermarkets and retailers to reduce packaging as part of an anti - waste campaign. The campaign was initiated by The Independent newspaper. Britain generates 4.6 million tons of household waste every year by packaging.
Dozens of people have expressed anger at the excess of plastic wrapping. Campaigners have called on Britain to learn from other European countries, In Belgium, when you buy something in a plastic or glass container, you make a deposit. When returned bottles are put in a vending machine 自动售货机, the deposit is refunded. Environmentalists warn that Britain lags behind in this.
There were reports of growing unease among consumers over the amount of packaging they have to deal with. Trade standards officers also object to excessive packaging. This is because too much padding can give buyers a false impression of what they are buying.
In response to a campaign by Britain's The Independent newspaper, leading supermarkets have pointed to various initiatives to win the public confidence. ____
But campaigners said retailers and the government could learn much from anti - waste practices on the Continent. In Sweden, non - recyclable batteries have been taxed since 1991 to encourage a switch to alternatives. This has resulted in a 74 percent reduction in sales. In Germany, plastic bags are unheard of in supermarkets and deposits are paid for reusable plastic and glass beverage bottles.

5、Cancer
Cancer is a group of many related diseases that begin in cells, the body's basic building blocks. The body is made up of many types of cells. Normally cells grow and divide to produce more cells as they are needed to keep the body healthy. Sometimes, this orderly process goes wrong. New cells form when the body does not need them, and old cells do not die when they should. The extra cells form a mass of tissue called a growth or tumor. Benign (良性的) tumors are not cancer. They can often be removed and, in most cases, they do not come back. Malignant (恶性的) tumors are cancer. Cells in malignant tumors are abnormal and divide without control or order.
Scientists have learned that cancer is caused by changes in genes that normally control the growth and death of cells. Certain lifestyle and environmental factors can change some normal genes into genes that allow the growth of cancer. Many gene changes that lead to cancer are the result of tobacco use, diet, exposure to ultraviolet radiation from the sun, or exposure to carcinogens (致癌物) in the workplace or in the environment. Some gene alterations are inherited.
Cancer treatment can include surgery, radiation therapy, chemotherapy （化疗), hormone therapy, and biological therapy. The doctor may use one method or a combination of methods, depending on the type and location of the cancer, whether the disease has spread, the patient's age and general health, and other factors. Because treatment for cancer can also damage healthy cells and tissues, it often causes side effects. Patients and doctors generally discuss the treatment options, weighing the likely benefits of killing cancer cells and the risks of possible side effects.
Having cancer does not always mean having pain. Whether a patient has pain may depend on the type of cancer, the extent of the disease, and the patient's tolerance for pain. Most pain occurs when the cancer grows and presses against bones, organs, or nerves. Pain may also be a side effect of treatment. However, pain can generally be relieved or reduced with prescription medicines or over-the-counter drugs recommended by the doctor.
Gene alterations may be caused by____.
【单选题】

A.prescription medicines

B.control or order

C.tolerance for pain

D.various factors

E.normal genes

F.different genes side effects

正确答案:D

答案解析:根据题干线索词Gene alterations定位原文至第二段第二句“Certain lifestyle and environmental factors can change some normal genes into genes that allow the growth of cancer”，题干中的alterations与句中的change虽然词性不同，但意思相同。题干将该句由主动态变为被动态，由此推断，句中画线部分即为题干所需添加成分。而D选项various factors是对该部分的同义改写，故为正确答案。
