10.It is very common that many students complain they lack concentration.For example,"I can't concentrate.""My mind wanders when I try to study."
We all have the ability to concentrate.Think of the times when you were attracted to a super novel or the times when you were playing your guitar or piano.But at other times your mind races from one thing to another.Here are some tips.
Rest from time to time.Remember to take short breaks.Lectures are usually 50minutes long,and that's about the length of time most people can direct their attention to one task.But that's just an average.Your concentration time might be shorter (20-35minutes) or longer (perhaps 90minutes).When you take a break,you get more oxygen to your brain!When we sit for long periods,blood tends to be pooled in our lower body and legs.Get up and walk around the room for a couple of minutes.As a result,more oxygen is carried to the brain and you can concentrate better.
         If you study one subject for a long time,you may find it hard to concentrate.Many students improve their concentration by changing one subject to another every one to two hours.In this way you can pay more attention to something that's different.
Reward yourself.Give yourself a reward when you've completed a task.The task might be small,such as staying with a difficult paper until you've finished.But giving yourself a reward can help you be more interested in doing other tasks.
Increase your activity level.Your concentration wanders more easily if you just read an article straight through.Instead,take the heading for each part and turn it into a question.For this part,that would be,"How can I increase my activity level while studying?"Then study that part to answer that question.Do this routinely.The questions give us a focus for each part and increase our involvement(参与).

60.According to Paragraph 3,what's the purpose of walking around?B
A.To help us stay fit.
B.To provide the brain with more oxygen
C.To benefit our lower body.
D.To increase our concentration time to 90minutes.
61.What's the best title for Paragraph 4?C
A.Study for one hour each time.
B.Do something difficult.
C.Change subjects.
D.Study in different ways.
62.In the last paragraph,the writer suggests thatD.
A.we just read the heading of some articles
B.we do our best to read an article straight through
C.we ask other people questions about the article we are reading
D.we ask ourselves questions about what we are reading
63.The writer wrote the passage toC.
A.encourage us to try to concentrate
B.give us the reasons for a lack of concentration
C.teach us how to concentrate while studying
D.list the benefits we can get from concentration.

分析 本文主要介绍了变换科目集中注意力的方法.

解答 BCDC
60  B  细节题.由第三段最后两句"Get up and walk around the room for a couple of minutes.As a result,more oxygen is carried to the brain and you can concentrate better."可知在屋里走一走能够使更多的氧气输送到大脑,从而帮助集中注意力,故正确答案为B.
61  C  主旨题.文章第四段主要介绍了变换科目以集中注意力的方法,由第二句"Many students improve their concentration by changing one subject to another every one to two hours."可知C项符合文意,故正确答案为C.
62  D  细节题.由最后一段第三句"Instead,take the heading for each part and turn it into a question."和最后一句"The questions give us a focus for each part and increase our involvement(参与)."可知作者建议我们在阅读时提出问题,以提高注意力和增加参与性,故正确答案为D.
63  C  主旨题.文章第一、二段引出对集中注意力的讨论,第三、四、五、六段分别介绍了注意休息、变换科目学习、奖励自己和提高活跃性这四个帮助集中注意力的方法.再由第二段最后一句"Here are some tips."可知文章是关于在学习时集中注意力的一些建议,即教我们集中注意力的方法,故正确答案为C.

点评 做阅读理解时要快速的浏览全文,把握文章主旨大意,带着问题回到原文,寻找细节或概括相应的答案,最后要理清作者写作思路.

1.Baseball is as American as apple pie and country music.And if you're vacationing in a U S city with a professional baseball team,there is no better way to spend a summer afternoon or evening than at a baseball game with the kids.Not only does the baseball outing offer families an affordable experience that recalls a simpler time,it engages kids in one of America's favorite pastimes.Whether watching their favorite team or viewing a baseball game for the first time,your kids will quickly be cheering with the crowd.
There is more to a family outing at the ballpark than the game on the field.Each year Major League Baseball clubs offer a variety of specials,promotions and giveaways to attract young fans and their families to the ballpark.From bobble-head player figurines,player T-shirts,hats,trading cards,lunchboxes and more,teams are eagerly handing out fun and free stuff at the gate ( usually to kids 14and under).Many clubs with open-air parks have regularly scheduled fireworks displays and some allow kids to run the bases after select games.
While the price of tickets to Major League Baseball games has increased in recent years,baseball is still the most affordable professional sport in America to see live.And thanks to tiered (层级的) pricing,you can pay as little as US 5forbleacherseatsorasmuchasUS 110for the best seats in the park.Many ballparks feature family sections,in less expensive areas which prohibit the consumption of alcohol.And although adults may prefer the perspective available from seats close to the field,the crowd rather than the location is likely to define the experience for the kids.
Minor League Baseball,readily available in many small towns and cities across the United States,is another option for families.In addition to being a less expensive way for a family to enjoy America's favorite pastime,minor league games typically offer a more intimate fan experience.The parks are smaller and fans often have access to the players.

58.Why are you advised to spend time at a baseball game with the kids?C
A.It costs little to watch a baseball game.
B.Baseball games are very attractive to kids.
C.You can experience one of America's favorite pastimes.
D.You can taste apple pies at the same time.
59.Why do baseball club offer specials,promotions and giveaways?D
A.To thank fans for their support.
B.To ask fans to cheer for them.
C.To entertain the fans.
D.To attract people to the ballpark.
60.Baseball is still the most affordable professional sport in America to see live becauseD.
A.there are clubs in almost every city
B.many ballparks feature family sections
C.people don't need to pay much to see a game
D.it has a special pricing system
61.What do kids care about most during a baseball game?A
A.The crowd.B.Price of the game.

15.It is a long time since I took up teaching.During my teaching career,I often ask my student to read the text until they can recite them,and I tell them that recitation is an important part of their homework.However,some of my students are tired of doing so,thinking that it is both hard and useless.They argue that it takes a long time to recite a text from memory and text itself never appears in a test paper.
In my opinion,it naturally takes time to recite a text,but it is worth doing so.When you are able to recite a text,you are sure to be familiar with the words and expressions.When you need them in reading or writing or doing exercises,they will come to your mind quickly,and so you will give quick response to all kinds of language situation.How can we say that it is useless?
Besides,many students complain that they soon forget what they were once able to recite.This is true,but you don't need to worry.While you are reading and forgetting the texts,your language level is being raised.Sure you don't remember your Chinese texts that you once read in the primary school,but now you are able to read novels and newspaper.So,recitation of the texts will help you improve your language ability.
28.What do the students think about the teacher's advice?A
A.The English teacher asks them to do something useless.
B.The English teacher is very kind to them.
C.The English teacher should let them study on their own.
D.The English teacher tries his best to help them with English.
29.According to the text,which of the following is correct?B
A.The teacher thinks the students are too naughty to learn English well.
B.The students think they spend a lot of time in reciting the texts and get nothing.
C.The students say that they often forget the words.
D.The students take no interest in English.
30.When the students are against his suggestion,the writerC.
A.often criticizes them                  
B.wants to give up his idea  
C.patiently explains to them why they should recite the texts
D.is afraid that he is criticized by the headmaster.
31.Why does the writer suggest that the students recite the text?D
A.Reciting the texts can greatly improve the classroom teaching.
B.Reciting the texts is the best way of learning English.
C.The students should remember all the texts that the teacher has taught them.
