9.Animals have been killed for their fur and feathers,and (61)thousands(thousand) of kinds of animals have disappeared from the world forever.About 170kinds in the US alone(62)are considered  (consider) in danger.
Why should people care?(63)Because we need animals,and if they are gone,there will never be any more.Every animal has its place in the balance of nature.(64)Destroying(destroy) one kind of animal can create many problems.For example,when farmers killed large numbers of hawks (老鹰),the farmers'stores of corn and grain were destroyed (65)by rats and mice.With no hawks to keep down their numbers,the rats and mice multiplied (繁殖) (66)quickly(quick).
Luckily,some people are working (67)to help(help) save the animals.Some groups raise money to let people know about (68)theproblem.And they try to get the governments to pass laws protecting animals in danger.Quite a few(69)countries(country) have passed laws.These laws forbid the killing of any animals on the danger list.Slowly,the number of some animals in danger(70)is(be) growing.

分析 本文讲述了由于人类对动物的肆意捕杀,使得很多种动物濒临灭绝,这将会导致自然界生态失衡,从而引发恶性循环.

解答 61.thousands;考查名词,当hundred,thousand和million等词后面有of时,hundred,thousand和million要用复数形式.
62.are considered;考查动词的语态,主语About 170kinds in the US与动词consider是动宾关系,故用被动语态are considered.
63.Because;考查原因状语,有前面问句中的why可知此处要用because回答.
64.Destroying;考查非谓语动词,这里用动名词短语 Destroying one kind of animal 作句子的主语.
65.by;考查介词,此处介词by用于被动语态中,表示动作的使用者.
66.quickly;考查副词,此处用副词作状语修饰动词multiplied.
67.to help;考查动词不定式,此处用不定式短语在句中做目的状语.
68.the;考查冠词,此处讲的是上文提到的生态失衡问题,故用the表示特指.
69.countries;考查名词单复数,country是可数名词,前面有 a few(一些)修饰,故用复数形式countries.
70.is;考查主谓一致,主语the number 是单数形式,故动词用is.

点评 通过快速阅读短文了解短文的基本大意,再分析句子间的结构关系,从词义,词性,固定短语,句式结构等方面去找文中存在的错误加以修改.

4.Friendship-Seven Tips on How to Make Friends
Friendship is a very important human relationship and everyone needs good friends.Friendship offers companionship,improves an individual self-worth and promotes good health.However making new friends comes easy for some people but for many of us the process is difficult and requires courage.Below are some helpful tips on how to make and keep friends.
Associate with others.The first step to making friends is associating with other people.Health clubs,places of worship and charities are some places where you can meet new people and build friendship.But attending these places is not enough.You will need to make yourself known by becoming an active member.
Be cheerful.A smile on the face is a sure way to attract new friends.No one wants to keep company with someone who constantly looks upset.
Start a conversation.Starting a conversation is the second most important step in making new friends.Do not wait to be spoken to;you can always start the conversation.Being able to make small talk is a very useful skill in relating with other people regardless of the environment or circumstance.
Stay in touch.For a friendship to grow you need to stay in touch.There are several ways of staying in touch with your friends and these include SMS,phone calls and online social networking sites.
Do things together.Choosing friends with common interest is important in establishing friendship as these interests would always bring you and your friend together and hanging out will always be a pleasant experience.The less you have in common with your friend the more likely the friendship will not grow.
Let it grow.It is a good thing to stay in touch but try not to choke your new friend with calls,messages or visits as this would likely wear him or her out and eventually they may not want to be your friend anymore.The best friendships are the ones that grow naturally.
Enjoy your friendship.The best way to enjoy your new friends is to allow them to be themselves.Try not to be critical (挑剔的) of them and try not to change them from who they are to what you want them to be.
