1、Module 5A Lesson in a LabSection Grammar能力提升.阅读理解AScience experiments are a fun way for kids to learn all about science.I will introduce a few great experiments and teach your child all about the wonders of inertia (惯性)Coin ShootYoull need some coins, at least eleven, and a smooth table.Stack (堆叠) a
2、ll but one of the coins on the smooth table, making sure that the “high rise” is straight.Coins with wide edges make this experiment easy to do.Flick (弹) the extra coin quickly towards the bottom of the stack so that it hits the bottom coin.The bottom coin from the stack should shoot out from under
3、the other coins without changing the rest of the stack.With good aim and quick flicks of your finger, you should be able to shoot all of the coins out of the stack one by one.Because the inertia of the stack of coins is so great, the force from the flicked coin is not enough to make the entire stack
4、 move or fall down.The Pencil StandingPlace a narrow piece of paper on a smooth table.Hold the paper so that most of it hangs off the table.Place a pencil on the paper so that it is standing straight.Now, slowly try to pull the paper out from under the pencil.What happens? Set up the paper and penci
5、l again, and give the paper a fast pull.What happens to the pencil this time?Since the still pencil wants to stay at rest, it will be against the fast movement of the paper.This means that when the paper is moved quickly out from under the pencil, the pencil remains standing straight.If the paper is
6、 moved slowly, the movement has a chance to influence the pencil, and it will fall down.【语篇解读】科学实验能够帮你直观地探索科学奥秘。本文教你如何了解惯性的存在。1Which of the following is used in both of the two experiments?AA narrow piece of paper.BA number of coins.CA smooth table.DA new pencil.解析：选C细节理解题。由第二段第一句和第三段第一句可知，两个实验中都用到了
7、a smooth table。2What result can we get if we do the first experiment well?AThe stack of coins fall down on the table.BThe bottom coin is flicked out of the stack.CAll of the coins are taken away from the table.DAll of the coins are shot out of the stack one by one.解析：选D细节理解题。根据第二段倒数第二句可知，如果将这个实验做好，摞
8、起来的硬币会一枚一枚地被击出。3Most of the paper hangs off the table so that _.Awe can pull it quicklyBwe can take hold of itCit can influence the pencilDthe pencil can stand straight解析：选A推理判断题。根据第三段倒数第二句“Set up the paper and pencil again，and give the paper a fast pull.”可推知，这样放纸条是为了能够迅速地抽出纸条，故答案为A项。4If we pull the
9、 paper slowly out from under the pencil, the pencil will _.Amove slowly with the paperBstand straight on the tableCbe shot out from the tableDfall down on the table解析：选D细节理解题。根据文章最后一句可知，如果慢慢地抽出铅笔下面的纸条，那么纸条就会影响到铅笔，铅笔就会倒在桌子上。BIf you want to stay young, sit down and have a good think. This is the resea
10、rch finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise and, as a result, we are growing old unnecessarily soon.Professor Taiju Matsuzawa wanted to find out why quite healthy farmers in northern Japan appeared to be losing their ability to think and
11、 reason at a rather early age，and how the speed of getting old could be slowed down.With a team of researchers at Tokyo National University, he set about measuring brain volumes (脑量) of a thousand people of different ages with different jobs. Computer technology helped the researchers to get most ex
12、act measurements of the volume of the front and side parts of the brain, which have something to do with intellect and feelings, and decide the human character.As we all know, the back part of the brain, which controls the tasks like eating and breathing, does not contract (萎缩) with age.Contraction
13、of front and side partsas cells die offwas seen in some people in their thirties, but it was still not found in some sixty and seventyyearolds.Matsuzawa concluded from his tests that there is a simple way to prevent the contractionusing the head.The findings show that contraction of the brain begins
14、 sooner in people in the country than in the towns.“Those with least possibility，” says Matsuzawa, “are lawyers, followed by university professors and doctors.White collar workers doing the same work day after day in government offices are, however, as possible to have contracting brains as the farm
15、 workers, bus drivers and shop assistants.”【语篇解读】文章介绍了一项研究的发现：不经常用脑的人的大脑比经常用脑的人要萎缩得早。所以要想保持大脑的年轻，就要多使用大脑。5The team of doctors wanted to find out _.Aat what point people grow mentally oldBhow to make people live longerCthe size of certain peoples brainsDwhich people are the most clever解析：选A主旨大意题。由第二段
16、可知，这项调查是想弄清楚为什么人会在精神上变老，A项符合题意。6Their research findings are based on _.Aan examination of farmers in northern JapanBtests given on a thousand old peopleCexamining the brain volumes of different peopleDusing computer technology解析：选C细节理解题。由第三段第一句“With a team of.with different jobs.”可知，这项研究是建立在对1 000个人
17、的脑量的检测的基础之上的。7The researchers tests show that _.Aour brains contract as we grow olderBone part of the brain does not contractCsixtyyearolds have better brains than thirtyyearoldsDsome peoples brains have contracted earlier than other peoples解析：选D细节理解题。由第四段的句子“Contraction of front and side partsas ce
18、lls die offwas seen in some people in their thirties.”可知，有的人的大脑萎缩得比其他人早。8The most possible conclusion of the passage is that _.Amost of us take more exerciseBits better to live in the townCthe brain contracts if it is not usedDthe more one uses his brain, the sooner he becomes old解析：选C推理判断题。由倒数第二段的句
19、子“Matsuzawa concluded from his tests that there is a simple way to prevent the contractionusing the head.”可推知，人的大脑不经常使用会萎缩。.短文改错(2019成都七中高一月考)Hello, boys and girls！Today，I am going to talk with what you should do when a fire alarm go off.
