【正文】 em答案：B解析：：當顧客申訴商品有質(zhì)量問題時，態(tài)度要堅定、有禮貌，特別是如果消費者當場演示就能最有效地達到申訴目的。s better to plain to _____.A. a shop assistantB. the store managerC. the manufacturerD. a public organization答案：B解析：。所以A、B、C均不是正確答案。B“威脅將此事向法庭上訴”是在經(jīng)理未能解決問題，寫信給廠家也未能解決問題時才使用的方法，所以它也不是解決問題的第一步。所以D“向這家商店出示書面證明”，與原文相符，是正確答案。s favour, assuming he or she has a just claim.Consumers shoud plain in person whenever possible, but if they cannot get to the place of purchase, it is acceptable to phone or write the plaint in a letter.Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can demonstrate what is wrong with the item in question. If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example, The left speaker does not work at all and the sound ing out of the right one is unclear is better than This stereo(立體聲音響does not work.The store manager may advise the consumer to write to the manufacturer. If so, the consumer should do this, stating the plaint as politely and as firmly as possible. But if a polite plaint does not achieve the desired result, the consumer can go a step further. She or he can threaten to take the seller to court or report the seller to a private or public organization responsible for protecting consumers‘rights. a consumer finds that his purchase has a fault in it, the first thing he should do is to _____.A. plain personally to the managerB. threaten to take the matter to courtC. write a firm letter of plaint to the store of purchaseD. show some written proof of the purchase to the store答案：D解析：。When a consumer finds that an item she or he bought is faulty or in some other way does not live up to the manufacturer39。原句意為：人類很自然地最容易對那些具有征兆的疾病印象深刻，然而有些最致命的疾病卻是慢慢地毫無察覺地擊中他們的。remarks that _____.A. people find invisible diseases difficult to deal withB. attacks by hidden enemies tend to be fatalC. diseases with obvious signs are easy to cureD. people tend to overlook hidden dangers caused by pesticides答案: D詳解：D。只有C)項“危險并沒有立刻顯示出來”，符合原文意旨，特別是最后一句的句意，所以C)是正確答案。再看B)：現(xiàn)在比將來重要。根據(jù)第三段內(nèi)容可知，有毒化學物質(zhì)的生物效果是累積的，而且累積越多，危險越大，因此，即使是有限的吸收，也會有潛伏的危險，可見A)項內(nèi)容錯誤。本題可用篩選法，一一排除錯誤答案。s healthB. the present is more important for them than the futureC. the danger does not bee apparent immediatelyD. humans are capable of withstanding small amounts of poisoning答案: C詳解：C)。而B)、C)、D)項的內(nèi)容在文中均未提及，所以無法判斷是否是作者的觀點，因而不能入選正確答案。本題的答案主要見于第二段。t do without pesticides in farming答案: A詳解：A)。23. In the author39。同時，作者在文中并未悲天憫人，認為殺蟲劑的危害已不可救藥，所以A)項“悲觀的”也不符合題意。本文就作者對殺蟲劑的環(huán)境后果的態(tài)度提問。s attitude towards the environmental effects of pesticides?A. Pessimistic.B. Indifferent.C. Defensive.D.

We have seen that they now pollute soil, water, and food, that they have the power to make our streams fishless and our gardens and woodlands silent and birdless. Man, however much he may like to pretend the contrary, is part of nature. Can he escape a pollution that is now so thoroughly distributed throughout our world?We know that even single exposures to these chemicals, if the amount is large enough, can cause extremely severe poisoning. But this is not the major problem. The sudden illness or death of farmers, farm workers, and others exposed to sufficient quantities of pesticides is very sad and should not occur. For the population as a whole, we must be more concerned with the delayed effects of absorbing small amounts of the pesticides that invisibly pollute our world.Responsible public health officials have pointed out that the biological effects of chemicals are cumulative over long periods of time, and that the danger to the individual may depend on the sum of the exposures received throughout his lifetime. For these very reasons the danger is easily ignored. It is human nature to shake off what may seem to us a threat of future disaster. Men are naturally most impressed by diseases which have obvious signs, says a wise physician, Dubos, yet some of their worst enemies slowly approach them unnoticed.21. Which of the following is closest in meaning to the sentence Man, ... is part of nature.(Line 3,)?A. Man appears indifferent to what happens in nature.B.

Man can escape his responsibilities for environmental protection.答案: B詳解：B)。 there any other factors that might affect the development of a child _____ e
