My little cousin is greatly interested on science．And he does some dangerous experiments sometime．Although his parents want to encourage him to be great scientist，at times they worry about his safety．Last week，when my cousin was doing an experiment，he hurts his thumb．My aunt felt sadly and wanted him to stop from doing that experiment．However，my cousin didn't want to give up．She said，"Many scientists got hurt when they were doing experiments，so they didn't give up．"My aunt had to let him finish the experiments and he finally succeeded in finish it．

分析 作者在本文中講述了表弟熱愛科學(xué)，經(jīng)常做一些科學(xué)實(shí)驗(yàn)，有一次做實(shí)驗(yàn)傷了大拇指，盡管媽媽勸他停下來，但他仍不放棄，最終實(shí)驗(yàn)成功．

解答 My little cousin is greatly interested on science．And he does some dangerous experiments sometime．Although his parents want to encourage him to be∧great scientist，at times they worry about his safety．Last week，when my cousin was doing an experiment，he hurts his thumb．My aunt felt sadly and wanted him to stop from doing that experiment．However，my cousin didn't want to give up．She said，"Many scientists got hurt when they were doing experiments，so they didn't give up．"My aunt had to let him finish the experiments and he finally succeeded in finish it．
詳解：
1．on 改為in；考查介詞，be interested in…是固定搭配，意為"對(duì)…感興趣"．
2．sometime改為sometimes；考查副詞，sometimes是副詞，意為"有時(shí)"；sometime意為"在某一時(shí)候"，分析句意為"有時(shí)候他做一些危險(xiǎn)的實(shí)驗(yàn)"故用sometimes．
3．be后面加 a；考查冠詞，scientist是一個(gè)可數(shù)名詞，前面用冠詞a泛指"一個(gè)"，一個(gè)偉大的科學(xué)家．
4．hurts改為hurt；考查動(dòng)詞的時(shí)態(tài)，根據(jù)時(shí)間狀語Last week可知句子要用一般過去時(shí)，動(dòng)詞hurt的過去式和過去分詞和原形一樣．
5．sadly改為sad；考查形容詞，此處用形容詞sad放在系動(dòng)詞feel后面，構(gòu)成系表結(jié)構(gòu)．
6．去掉from；考查固定短語，stop doing sth意為"停止做某事"．句意：想要他停止做這個(gè)實(shí)驗(yàn)．
7．She 改為He；考查人稱代詞，本句的主語是my cousin，是男性，故使用he．
8．so 改為but；考查連詞，分析句意為"很多科學(xué)家在做實(shí)驗(yàn)的時(shí)候都受傷，但是他們都沒有放棄"．所以下文之間存在著轉(zhuǎn)折關(guān)系，故用but．
9．experiments改為experiment；考查名詞，上文只提及這個(gè)實(shí)驗(yàn)，是一個(gè)單數(shù)名詞．
10．finish改為finishing；考查非謂語動(dòng)詞，介詞in后面接動(dòng)名詞doing形式，succeeded in doing意為"成功做某事"．

點(diǎn)評(píng) 通過快速閱讀短文了解短文的基本大意，再分析句子間的結(jié)構(gòu)關(guān)系，從詞義，詞性，固定短語，句式結(jié)構(gòu)等方面去找文中存在的錯(cuò)誤加以修改．

2．Americans use the term"college students"to mean students either in colleges or universities．Not only that，Americans almost never say"going off to university"or"when I was in university．"That sounds British．（71）GCollege，university：what's the difference？（72）F．Both offer undergraduate degrees in the arts and sciences，for example．And both can help prepare young people to earn a living．
But many colleges do not offer graduate studies．Another difference is that universities are generally bigger．（73）D
Another place of higher education，especially in technical areas，is an institute，like the Massachusetts Institute of Technology．Yet even an institute of technology can offer a wide choice of programs and activities．
Modern universities developed from those of Europe in the Middle Ages．The word"university"came from the Latin universities，describing a group of people organized for a common purpose．
（74）C．In England，colleges were formed to provide students with places to live．Usually each group was studying the same thing．So college came to mean an area of study．
The first American universities divided their studies into a number of areas and called each one a college．This is still true．（75）B．For example，Harvard College is the undergraduate part of Harvard University．
Programs in higher learning can also be called schools，like a school of engineering or a medical school within a college or university．You know，learning all these terms is an education in itself．

A．There are more universities than colleges in the USA．
B．A college can also be a part of a university．
C．"College"came from collegium，a Latin word with a similar meaning．
D．They offer more programs and do more research．
E．Universities and colleges offer students different opportunities．

17．Teamwork is just as important in science as it is on the playing field or in the gym．Scientific investigations （調(diào)查） are almost always carried out by teams of people working together．Ideas are shared，experiences are designed，data are analyzed，and results are evaluated and shared with other investigators．Group work is necessary，and is usually more productive than working alone．
Several times throughout the year you may be asked to work with one or more of your classmates．Whatever the task your group is assigned，a few rules need to be followed to ensure a productive and successful experience．
What comes first is to keep an open mind，because everyone's ideas deserve consideration and each group member can make his or her own contribution．Secondly，it makes a job easier to divide the group task among all group members．Choose a role on the team that is best suited to your particular strengths．Thirdly，always work together，take turns，and encourage each other by listening，clarifying，and trusting one another．Mutual support and trust often make a great difference．
Activities like investigations are most effective when done by small groups．Here are some more suggestions for effective team performance during these activities：Make sure each group member understands and agrees to the task given to him or her，and everyone knows exactly when，why and what to do； take turns doing various tasks during similar and repeated activities； be aware of where other group members are and what they are doing so as to ensure safety； be responsible for your own learning，though it is by no means unwise to compare your observations with those of other group members．
When there is research to be done，divide the topic into several areas，and this can explore the issue in a very detailed way．You are encouraged to keep records of the sources used each person，which helps you trace back to the origin of the problems that may happen unexpectedly．A format for exchanging information （e．g．photocopies of notes，oral discussion，etc．） is also important，for a well-chosen method not only strengthens what you present but also makes yourself easily understood．When the time comes to make a decision and take a position on an issue，allow for the contributions of each member of the group．Most important of all，it is always wise to make decisions by compromise and agreement．
After you've completed a task with your team，make an evaluation of the team's effectiveness-the strengths and weaknesses，opportunities and challenges．

2．Ways to save timeWe all wish we had just a bit more time．Just think what you could do with an extra hour or two each day：you could finally stick to an exercise routine，or spring-clean the house，or write your novel，or learn the guitar and so on．
（36）D  But I can help you find more hours in your day for the things that really matter．
Ⅰ．Get Out of Bed Earlier
If you normally get up at 7：30a．m．，try getting up at 7：00a．m．That half-hour might not sound like much，but it could be time that you use to exercise，to read that book you've been meaning to finish．（37）F
Ⅱ．Do the Important Tasks First
Once you get to work，get the important ones done first （not the easy ones，or even the urgent ones）．You can afford to spend at least an hour working on big，important tasks rather than on all those little urgent ones．
（38）C The urgent tasks will still get done，and you won't miss the important ones．
Ⅲ．Reduce Interruptions
If colleagues have a habit of hanging around your desk to chat，or if the phone is constantly ringing，you might find that it takes you half the day to finish a simple task like writing a letter．Constant interruptions don't just eat up time，they also break your concentration．
When you've got a big task to focus on，let your calls go to voicemail．（39）A Wearing headphones makes it less likely that people will try to strike up a conversation．
Ⅳ．（40）G
A few minutes chatting，browsing the web，and so on，can easily turn into hours of wasted time over the course of a day．
When you're working，work．If your concentration is slipping，take a proper break：go and get a glass of water，or stretch your legs a bit．And if you're facing a difficult task，try breaking it into small steps or stages so that it's easier to deal with．
A．If you have an office door，close it．
B．Take Breaks When Necessary
C．If you work like this，you'll usually save time．
D．I can't magically make all your days 25hours long．
E．Would you want me to make your day longer？
F．Or simply to get your day off to a calm and organized start．
G．Stay Focused on Your Work．
