【文章內(nèi)容簡(jiǎn)介】 rovinces. In his words, the data and facts are convincing and this range of ages and locations across the country provided a real, objective and representative sample. The researchers noted that the effect of air pollution on verbal ability is even more serious as people age, especially among men and the less educated. The researchers also stressed that every country, whether developed, developing or poor, should focus on air pollution or humans will face a bad situation.（1）What is the result of the study? pollution has a bad effect on people39。s intelligence. are more affected by air pollution than males. are more affected by air pollution than Chinese. working indoors are actually not affected by air pollution.（2）What did Chen say about the study? is doubtful. is extremely unfair. is mon and not representative. is relatively objective and persuasive.（3）What did the researchers emphasize in the last paragraph? data from the 33 provinces is convincing. whole world should pay attention to air pollution. less educated take more responsibility for air pollution. pollution39。s influence on verbal ability is less serious as people age.（4）Where is the text most likely taken from? life diary. guidebook. science magazine. biography.【答案】 （1）A（2）D（3）B（4）C 【解析】【分析】本文是一篇說(shuō)明文，一項(xiàng)新的研究表明，長(zhǎng)期暴露在空氣污染中會(huì)在語(yǔ)言和數(shù)學(xué)兩個(gè)方面影響一個(gè)人的智力，因此每個(gè)國(guó)家都應(yīng)關(guān)注空氣污染否則人類將面臨一個(gè)糟糕的局面。 （1）考查細(xì)節(jié)理解。根據(jù)第二段中的“The researchers reported that longterm exposure to air pollution can affect a person39。s mental abilities in two areas: Language and math.”可知，研究人員報(bào)告說(shuō)，長(zhǎng)期暴露在空氣污染中會(huì)在兩個(gè)方面影響一個(gè)人的智力：語(yǔ)言和數(shù)學(xué)。即研究結(jié)果是空氣污染會(huì)對(duì)人們的智力產(chǎn)生不良影響。故選A。 （2）考查細(xì)節(jié)理解。根據(jù)倒數(shù)第二段中的“In his words, the data and facts are convincing and this range of ages and locations across the country provided a real, objective and representative sample.”可知，用Xi Chen的話說(shuō)，調(diào)查得到的數(shù)據(jù)和事實(shí)令人信服，全國(guó)各地的不同年齡和不同地方的人提供了真實(shí)，客觀和有代表性的研究樣本。即Xi Chen對(duì)這項(xiàng)研究說(shuō)的是“研究結(jié)果是相對(duì)客觀和有說(shuō)服力的?！惫蔬xD。 （3）考查細(xì)節(jié)理解。根據(jù)最后一段“The researchers noted that the effect of air pollution on verbal ability is even more serious as people age, especially among men and the less educated. The researchers also stressed that every country, whether developed, developing or poor, should focus on air pollution or humans will face a bad situation.”可知，研究人員指出，隨著人們年齡的增長(zhǎng)，空氣污染對(duì)言語(yǔ)能力的影響更加嚴(yán)重，尤其是在男性和文化程度較低的人群中。研究人員還強(qiáng)調(diào)，每個(gè)國(guó)家，無(wú)論是發(fā)達(dá)國(guó)家，發(fā)展中國(guó)家還是貧窮國(guó)家，都應(yīng)關(guān)注空氣污染否則人類將面臨一個(gè)糟糕的局面。因此在最后一段中研究人員強(qiáng)調(diào)了全世界應(yīng)該注意空氣污染。故選B。 （4）考查推理判斷。根據(jù)第一段“A new study shows that air pollution can cause a huge reduction in our intelligence. The study was a project involving researchers at Peking University in China and Yale University in the United States.”可知，本文的話題是研究表明空氣污染會(huì)大大降低人們的智力。該研究是一個(gè)由中國(guó)北京大學(xué)和美國(guó)耶魯大學(xué)的研究人員參與的項(xiàng)目。因此可以推斷出文章可能來(lái)自于科學(xué)雜志。故選C。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。5．閱讀理解 When you go to the doctor, you like to e away with a prescription．It makes you feel better to know you will get some medicine. But the doctor knows that medicine is not always needed. Sometimes all a sick person needs is some reassurance that all will be well. In such cases the doctor may prescribe a placebo. A placebo is a sugar pill, a harmless shot, or ail empty capsule. Even though they have no medicine in them, these things seem to make people well. The patient thinks it is medicine and begins to get better. How does this happen? The study of the placebo opens up new knowledge about the way the human body can heal itself. It is as if there was a doctor in each of us. The doctor will heal the body for us if we let it. But it is not yet known just how the placebo works to heal the body. Some people say it works because the human mind fools itself. These people say that if the mind is fooled into thinking it got medicine, then it will act as if it did, and the body will feel better. Placebos do not always work. The success of this treatment seems to rest a lot with the relationship between the patient and the doctor. If the patient has a lot of trust in the doctor and if the doctor really wants to help the patient, then the placebo is more likely to work. So in a way, the doctor is the most powerful placebo of all. A placebo can also have bad effects. If patients expect a bad reaction to medicine, then they will also show a bad reaction to the placebo. This would seem to show that a lot of how you react to medicine is in your mind rather than in your body. Some doctors still think that if the placebo can have bad effects it should never be used. They think there is still not enough known about it. The strange power of the placebo does seem to suggest that the human mind is stronger than we think it is. There are people who say you can heal your body by using your mind. And the interesting thing is that even people who swear this is not possible have been healed by a placebo．（1）What do we know about placebo according to the passage? A.It contains some sort of medicine.B.It won39。t function if you are negative about medicine.C.People who don39。t believe placebo can39。t be healed by it.D.Patients and doctors know clearly how it helps to heal the body.（2）Why is the doctor sometimes the most powerful placebo? A.The patient needs help badly．B.The patient believes in the doctor．C.The doctor knows better about your body．D.The doctor has carefully studied medicine．（3）What does the underlined word “it” in Paragraph 5 refer to? A.The placebo.B.The bad effect.C.The body.D.The medicine.（4）What is the passage mainly about? A.Placebo：Work on Your MindB.Placebo：The Most Powerful MedicineC.Placebo：The Best DoctorD.Placebo：Heal Your Body【答案】（1）A（2）B（3）B（4）A 【解析】【分析】本文是一篇說(shuō)明文，有時(shí)候病人的病并不是需要真正的藥物來(lái)醫(yī)治，而是需要醫(yī)生開一些安慰的藥劑，安慰病人的心理使病人的情緒得到舒緩，從而有利于病情的痊愈。(1)考查細(xì)節(jié)理解。縱觀全文可知，一些醫(yī)生仍然認(rèn)為，如果安慰劑有壞的影響，它應(yīng)該永遠(yuǎn)不會(huì)被使用，他們認(rèn)為對(duì)安慰劑仍然沒(méi)有足夠的了解。所以此處的it是指的安慰劑。故選A。(2)考查推理判斷。根據(jù)第二段中的“A placebo is a sugar pill，a harmless shot，or ail empty capsule．”可知安慰劑不會(huì)起到醫(yī)學(xué)上的作用。
