2、Why Is the Native Language Learnt So Well?How does it happen that children learn their mother tongue so well? When we compare them with adults learning a foreign language, we often find this interesting fact. A little child without knowledge or experience often succeeds in a complete mastery of the language. A grown-up person with fully developed mental powers, in most case, may end up with a faulty and inexact command. What accounts for this difference?Despite other explanations, the real answer in my opinion lies partly in the child himself, partly in the behavior of the people around him. In the first place, the time of learning the mother tongue is the most favorable of all, namely, the first years of life. A child hears it spoken from morning till night and, what is more important, always in its genuine form, with the right pronunciation, right intonation, and right use of words and right structure. He drinks in all the words and expressions, which come to him in a flash, ever-bubbling spring. There is no resistance: there is perfect assimilation.Then the child has, as it were, private lessons all the year round, while an adult language-student has each week a limited number of hours, which he generally shares with others. The child has another advantage: he hears the language in all possible situations, always accompanied by the right kind of gestures and facial expressions. Here there is nothing unnatural, such as is often found in language lessons in schools, when one talks about ice and snow in June or scorching heat in January. And what a child hears is generally what immediately interests him. Again and again, when his attempts at speech are successful, his desires are understood and fulfilled.Finally, though a child\'s "teachers" may not have been trained in language teaching, their relations with him are always close and personal. They take great pains to make their lessons easy.A child learning his native language has the advantage of having private lessons all the year round.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:题干大意：儿童学习母语的优势是可以常年上私人辅导课。借助常识判断该句的说法不正确。利用答案线索词all the year round，我们可以在第三段第一句中发现直接相关句。比较原句和题干的结构，发现不同之处在于as it were的结构。注意：部分结构的差异往往是设置了陷阱。实际上，as it were意为“仿佛是”。所以原文说的是“仿佛是”，而题干提到的却是“是”，所以问题句“不正确”。

3、Geology and Heap(1)The importance of particular metals in the human diet has been realized within the past few decades, and the idea that geology might be related to health has been recognized for a number of elements such as iodine, zinc and selenium. For example, soils with low iodine contents produce crops, and animals deficient in iodine. A lack of iodine in the human diet leads to some serious diseases.(2)The ultimate source of metals within the human body is rocks, which weather into soil, gaining or losing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require for growth. The water we drink contains trace elements leached from rock and soil. Thus the geology and geochemistry of the environment have effects on the chemistry and health of plants, animals and people.(3)So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems. Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested or metal-rich dust is inhaled. However, small children are particularly exposed to metal-rich topsoil in playgrounds and gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.(4)Heavy metals are persistent: they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up and rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer and are also known to cause poisoning(5)In contrast, naturally contaminated soils have not been subject too risk assessment studies and rehabilitation measures, despite the fact that they frequently possess metal concentrations well above those of such polluted by humans and above environmental quality criteria.(6)There is a vital need to understand the potential risks and long-term health effects of living on naturally contaminated soils. Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain and human body. Geologists should be part of such studies as they can provide the essential background information on rock and soil chemistry as well as the chemical forms of heavy metal pollution.Industrially contaminated sites usually require a thorough clean-up due to ____.【单选题】

A.industrially polluted soils

B.rock and soil chemistry

C.naturally polluted soils

D.the pathways of metals into the food chain

E.the element of iodine

F.the persistence of heavy metals

正确答案:F

答案解析:第4段涉及这一问题。受到工业污染的土壤含有重金属，而且重金属很稳定，不容易降解，所以要对重金属进行彻底的清除。

4、EducationWhen a teacher finds a way to make a real difference in the students\' lives that\'s what education is all about. Let me tell you a story. Back in 1944 we had a new student named Roger, he was the first black student in our school, and everyone had some pretty ignorant views on the subject of black people . The other kids weren\'t bad children; they were just copying their parents, and well, I\'m afraid most of their parents had some pretty ignorant views on the subject of black people . But as you know, when you\'re twelve years old, you\'re just starting to have your own opinions about things, and I knew this could be a very important moment in their education. I knew I could make a real difference, not only to little Roger , but to all the other kids, too, if just handled it the right way.I decided I had to try to make Roger into someone special. Not like a teacher\'s pet, I wanted the other children to ____ , not just a dark shape in the back of the room. So I went after him with questions in every class. He was a bright little boy, so it was easy enough for me to establish him as a smart person with real value. I was pretty pleased, because I could see Roger becoming more confident, and although the other kids were still not very friendly, at least they stopped being so nasty to him.But you know what really changed everything? One day I could see Roger\'s mind was wandering: and without thinking I threw an eraser in his direction. I only meant to get his attention, but the eraser hit his hand and sent his pencil flying. The whole class roared! And afterwards, of course, all the kids went up to Roger to laugh with him about it . That\'s how he became an individual, someone special, to talk to and make friends with and that\'s how I became "Dead - Eye Bean".【单选题】

A.was giving him a hard time

B.had some pretty ignorant views on the subject of black people

C.while they were enjoying the same class

D.not only to little Roger

E.start seeing him as a human being

F.all the kids went up to Roger to laugh with him about it

正确答案:E

答案解析:这是一个want sb. to do sth. 的句子结构。因后面要接动词原形，所以答案选E。

5、Travel Across AfricaFor six hours we shot through the barren (荒芜的) landscape of the Karoo desert in South Africa. Just rocks and sand and baking sun. Knowing our journey was ending, Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth, a beautiful leather notebook I\'d bought in a market in Mozambique.Southern Africa was full of stories and visions. We were almost drunk on sensations. The roaring (咆哮) of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana.And then the other things, dogs in the streets, whole families in Soweto livng in one room, a kilometre from clean water.As we drove towards the setting sun, a quietness fell over us. The road was empty and we hadn\'t seen another car for hours. And as I drove, something caught my eye. Something moved close enough to touch them, to smell their hot breath. I didn\'t know how long they had been there next to us.I shouted to Dan: "Look!" But he was in a deep sleep, his camera lying useless by his feet. They raced the car for a few seconds, then disappeared far behind us, a memory of heroic forms in the red landscape. When Daniel woke up an hour later I told him what had happened."Wild horses?" he said. "Why didn\'t you wake me up, Sophia?""I tried, but they were gone after a few seconds.""Are you sure you didn\'t dream it?""You were the one who was sleeping!""Typical," he said, "The best photos are the ones we never take."We checked into a dusty hotel and slept the sleep of the dead.The horses didn\'t come near the car.【单选题】

A.Right

B.Wrong

C.Not mentioned
