Thats the finding from a new study in JAMA Pediatrics that found some toys being marketed as l

13、anguage promoters got in the way of learning. Research shows that for kids to understand, speak and eventually read or write a language, they need to hear it lots of it. And its never too early for parents and caregivers to get talking. That explains the booming industry in talking electronic toys t

14、hat claim to help kids learn language. The study focused on roughly two-dozen children between the ages of 10 and 16 months old. Researchers outfitted them with little microphones tucked into special vests or shirts that could record the infants playing at home with Mom or Dad. 1. Whats the finding

15、of the new study in JAMA Pediatrics? 2. How many children does the research focus on? 1 【正确答案】 B 【试题解析】 新闻开头提到，包装上说有教育功能的 (educational)并不能真正让玩具有教育意义 (doesnt make it so)，意下之义即一些标榜有教育意义的玩具实际上并不能做到这一点，故 B正确。 A“一些玩具的包装对 小孩的健康有害 ”利用package一词作干扰，并没有实质根据。 C“有必要让孩子尽快多说话很有必要 ”符合事实，但并非研究的发现。 D中的 microphones具有

16、干扰性，因为录音最后提到研究人员把小麦克风塞进特殊背心或衬衫，用于记录，但这只是研究的过程，并不是研究发现的成果。 【知识模块】 听力 2 【正确答案】 D 【试题解析】 选项均为数字，可推断本题为数字题。新闻提到研究的对象是年龄在 10到 16个月的 24个孩子，故答案为 D。这道题主要考的是 dozen的用法，录音中提到 roughly two-dozen children，因为 a dozen是 12个， two dozen就是 24个了。 【知识模块】 听力 3 【听力原文】 In the last few years, the face of undocumented immigra

17、tion to the U.S. has changed and so has the business of human smuggling. Make no mistake, migrating illegally across the U.S.-Mexico border is a well established, booming business. Today on the show, we meet a businessman and a client in the evolving industry of human smuggling. For some context con

18、sider the changes in recent years: Mexican immigrants have actually been leaving America. Meanwhile, Central American immigration is on the rise. This shift caused alarm when unaccompanied children from Honduras, El Salvador and Guatemala started showing up at the border seeking shelter. A new wave

19、of people were making their way up through Mexico, trying to cross rivers and deserts to escape poverty and gang violence. And many of the people doing this were paying dearly for it. 3. What do we learn about the industry of human smuggling in the U.S.-Mexico border? 4. Whose immigration to America

20、 is on the rise? 3 【正确答案】 A 【试题解析】 新闻开头提到，在美国和墨西哥边境，非法移民的 “业务 ”体系完善，发展兴旺 (a well established， booming business)， A中 flourishing是 booming的同义表达，故 A为答案。 B“一个衰退的产业 ”和 C“被政府取缔 ”均与新闻内容相反。新闻中说有改变的是 undocumented immigration“没有身份的移民 ”，而不是“人口偷渡 ”这一行业。 【知识模块】 听力 4 【正确答案】 B 【试题解析】 新闻中提到墨西哥移民实际上正在逐渐离开美国，与此同时，中美洲

21、的移民数量在上涨，故 B为答案。原文是说墨西哥的移民实际上正在逐渐离开美国，并没有提到上涨，排除 A和 C。 D“洪都拉斯 ”在新闻末尾出现，但原文是说来自洪都拉斯、萨尔瓦多、危地马拉国家的孩子正在寻求避难所。 【知识模块】 听力 5 【听力原文】 Tucked inside the U.S. governments latest update to its official eating advice is this recommendation: “Drink water instead of sugary drinks“ also known as soda. The frankness

22、 of this statement is remarkable, in part, because the Dietary Guidelines released Thursday are, in other ways, anything but direct. For instance, as weve reported, instead of explicitly telling Americans to cut their intake of red and processed meats, as an advisory panel of nutrition experts had r

23、ecommended, the final guidelines hint at meat reduction in subtle terms. That change in messaging may have been linked to pressure from the meat industry. By contrast, the governments language on choosing water over sugary drinks is as clear as a glass of pure water. It is not, however, all that eas

24、y to find. We spotted it inside this MyPlate, My Wins tip sheet, part of a new campaign the U.S. Department of Agriculture also launched Thursday. MyPlate, if you recall, is the symbol of a dinner plate divided into portions of fruits and vegetables, grains and proteins that replaced the food pyrami

25、d released four years ago. MyPlate is for the general public. Its an image that ends up in nutrition education materials in doctors offices, textbooks, school cafeterias and lots of other places. 5. Whats the U.S. governments latest official eating advice? 6. Why does the final guide hint at meat re

26、duction in subtle terms? 7. Whats the target group of MyPlate? 5 【正确答案】 C 【试题解析】 录音开头提到美国政府更新的官方饮食建议是建议人们喝水而不要喝含糖饮料即苏打水，可以得出答案是 C。 A“含糖饮料 ”和 B“苏打水 ”都是新闻明确建议不要喝的， D“可乐 ”也是含糖饮料的一种，故排除。 【知识模块】 听力 6 【正确答案】 A 【试题解 析】 新闻中提到，最终的膳食指南只是用不明确的字眼 (subtle terms)来建议来降低食肉类，作出这一改变可能与来自肉类制造业的压力有关 (pressure from the

27、meat industry)，故 A正确。 【知识模块】 听力 7 【正确答案】 D 【试题解析】 新闻末尾提到， MyPlate is for the general public，说明 MyPlate的目标群体是一般大众，故答案是 D。因为新闻中提到水果蔬菜，会使人联想到B“肥胖人群 ”，但新闻主题是围绕健康的饮食建议展开 的，并没有刻意针对肥胖人群，故可排除 B。 A“小孩 ”和 C“偏瘦人群 ”均没有在新闻中提到。 【知识模块】 听力 Section B 8 【听力原文】 M: I really dont know what to do this summer. I cant affo

28、rd to just sit around, and there dont seem to be any jobs available. W: Why dont you try house-sitting? Last summer my friend Margaret house-sat for the Dodds when they went away on vacation. Mr. Dodd hired Margaret to stay in their house because he didnt want it left empty. M: You mean the Dodds pa

29、id Margaret just to live in their house? W: It wasnt that easy. She had to mow and water the houseplants. And when Eric house-sat for Mr. Cohen, he had to take care of his pets. M: House-sitting sounds like a good job. I guess its a little like baby-sitting except youre taking care of a house instea

30、d of children. W: The student employment office still has a few jobs posted. M: Do I just have to fill out an application? W: Margaret and Eric had to interview with the houseowners and provide three references each. M: That seems like a lot of trouble for a summer job. W: The houseowners want some

31、guarantee that they can trust the house-sitters. You know, they want to make sure youre not the type who will throw wild parties in their house, or move a group of friends in with you. M: House-sitters who do that sort of thing probably arent paid then. W: Usually they are paid anyway just because t

32、he homeowners dont want to make a fuss. But if the homeowner reported it then the house-sitter wouldnt get another job. So, why dont you apply? 8. What does the man want to do this summer? 9. What did the Dodds do when they went away last summer? 10. What is one responsibility the house-sitter proba

33、bly wont have? 11. What would happen if a homeowner reported a house-sitters bad behaviour? 8 【正确答案】 D 【试题解析】 推断题。男士说他不能只是闲着 (sit around)，但又没有现成的工作(jobs available)，说明他想干些工作、赚些钱， D项符合此意。对话开头往往是出题之处。 【知识模块】 听力 9 【正确答案】 A 【试题解析】 细节题。 A是对原文 hired Margaret to stay in their house的另一种表述方法，故为答案。 C是强干扰项，对话讨论

34、的并不是租房子，而是雇人看房子。提问处是考点，其实就是对上文叙述的一个总结。 【知识模块】 听力 10 【正确答案】 C 【试题解析】 细节题，选项都是家务事。 A、 D两项属于 take care of his pets的范围，而 B项则属于 water the houseplants的范围。排除 A、 B、 D三项，即可得到答案 C。此外， C是 baby-sitter的职责，与本对话的话题 (house-sitting)不一致。注意 except， instead of这类词出现的地方，往往是出题之处。 【知识模块】 听力 11 【正确答案】 C 【试题解析】 细节题。男士认为 有不良行

35、为的看管房子的人极有可能不会领到工资，女士说通常他们还是会拿到工资，因为房子主人不想生事，但是如果房子主人报告这事的话，那么看管房子的人将不会得到另一份工作了，可见选 C。本题出题点在 But后，听音时要注意语义转折处。 【知识模块】 听力 12 【听力原文】 M: Can you tell me something about the university shuttle bus system? This is such a large campus, and I have classes all over campus. I need to take the shuttle bus fro

36、m one class to another, or Ill never make it on time. W: What do you need to know? I think its a really great system. M: First of all, where does it go? W: The university shuttle bus system goes all over campus. It doesnt leave the campus; if you want to travel off-campus, youll need to take the cit

37、y bus system. But the university shuttle bus system will get you from one class to the next very efficiently. M: And how much does it cost? W: Its free, can you believe it? So you dont have to pay a cent to get all around the university campus. M: Thats really great. And how do I catch the shuttle b

38、us? W: Just look for one of the bright yellow shuttle bus signs, and go stand next to it. You can see the yellow shuttle bus signs all over campus. A shuttle bus will come along approximately every five minutes, so you shouldnt have to wait long. M: That all sounds good. Thanks for your help. W: No

39、problem. 12. What are the man and woman discussing? 13. What area does the university shuttle bus cover? 14. How much does the shuttle bus cost? 15. What color are the shuttle bus signs? 12 【正确答案】 D 【试题解析】 选项全是名词短语，问对话主题的几率颇大。对话的开头的第一句话就点出了答案所在，即 D。如果实在没有听懂第一句话，后面还有机会听出答案，因为全文讲的都是 the university bus

40、 system。 【知识模块】 听力 13 【正确答案】 A 【试题解析】 选项都是地点和范围，而且选项之间有包孕关系。在范围上， C包含 A、 B和 D，所以可以初步排除 C。听到第一句话讲的是 the university bus system，就可以排除 D(人家说了是校内巴士，怎么会包括校外地区呢 )。所以关键是要听清巴士线路是否通达全校。标志词组 “First of all”后面紧跟着一个问句，注意听答案。 A正确。 【知识模块】 听力 14 【正确答案】 A 【试题解析】 从选项可以看出，问的是 “多 少钱 ”，马上就知道一定是问巴士车票多少钱。根据关键表达 free(免费的 )和

41、 dont have to pay a cent，可知答案为 A。 【知识模块】 听力 15 【正确答案】 C 【试题解析】 看到选项都是颜色，就要格外留神听对话中出现颜色的地方。对话两次提到 yellow这个词，且未提及其他颜色，故不难得出答案 C。 【知识模块】 听力 Section C 16 【听力原文】 Jet lag, caused by traveling between time zones, is becoming a common problem for frequent travelers: for 49 percent it is only a nuisance and

42、for 45 percent it is a real problem. It is caused by disruption to the internal biological clock, and may lead to digestive problems, tiredness, and sleep disruption. Generally speaking, our biological clock is slightly disturbed if we just move into the next time zone, but jet lag becomes a problem

43、 once we have passed through three or four time zones. The body takes about one day to get over each hour of time difference. But the seriousness of jet lag problems also depends on our direction of travel. If we travel west we will be in advance of ourselves as far as our internal clock is concerne

44、d, and problems may arise. A west-to-east journey, on the other hand, makes us late compared to the local time. It often demands even greater effort in adjustment since we are not quick enough to catch up with the new time schedule. Therefore, a trip from New York to Los Angeles often causes fewer p

45、roblems than a Los Angeles-New York trip. 16. Whats the problem a person suffers from when traveling between time zones? 17. How many hours does one need to get over his jet lag problem if he travels across three time zones? 18. Whats the main purpose of the passage? 16 【正确答案】 A 【试题解析】 录音开头就提到 Jet l

46、ag，第 2句就说明它的起因是 “人体内部的生物钟被打乱 ”，故答案为 A。 【知识模块】 听力 17 【正确答案】 D 【试题解析】 数字题，一般要做记录并进行简单的运算。原文说到 1个小时的时差需要 1天来调整，那么 3个时区就是 3个小时的时差，所以应该用 3天即 72个小时， D正确。 【知识模块】 听力 18 【正确答案】 A 【试题解析】 主旨题。录音的话题是 jet lag problems，但只是客观陈述现象和原因，并未提及避免的方法 ，故 A对而 B错。 【知识模块】 听力 19 【听力原文】 A “blogger“ is a person who writes on an

47、Internet computer website called a “blog“. The word “blog“ is a short way of saying Web log, or personal website. Anyone can start a blog, and they can write about anything they like.

48、them. They contain links to other websites. And they provide a place for people to write their ideas and react to the ideas of others.
