A.achievedB.has achievedC.had achievedD.is achieving

分析 經(jīng)過過去幾十年的努力,中國已經(jīng)在許多領(lǐng)域,特別是在高科技領(lǐng)域里,取得了很大的進步.

解答 答案:B
根據(jù)句中的時間狀語"over the past few decades"可知,此處表達的是過去某一段時間里發(fā)生的事情對現(xiàn)在產(chǎn)生的影響或造成的結(jié)果,即:中國在許多領(lǐng)域里都取得了很大的進步,所以這里應(yīng)使用現(xiàn)在完成時;故選B.

點評 本題考查了現(xiàn)在完成時強調(diào)"影響性"的用法;做本題時,需要了解現(xiàn)在完成時除了強調(diào)動作的持續(xù)性以外,它還強調(diào)過去的動作對現(xiàn)在產(chǎn)生的影響以及造成的結(jié)果;例如:I have already seen the film.我已經(jīng)看過這部電影了.(對現(xiàn)在的影響是:我知道電影的內(nèi)容);I have lost my key.我把鑰匙弄丟了.(造成的結(jié)果是:我進不了門了.)

2.Facebook(臉譜網(wǎng))類似我們中國的QQ,在成立后很短的時間內(nèi),就擁有了眾多的用戶.Jane 是其中的一名用戶,她談到了Facebook的一些情況.請從下列A、B、C、D、E、F中選出與她的描述相匹配的主題.選項中有一項是多余選項.
A.Facebook's advertising 
B.Typical activities on Facebook
C.Suggestions about the future of Facebook
D.Trust with Facebook in personal information
E.Product purchase following Facebook's friends  
F.People's attitude towards the development of Facebook
61.B
Jane's description:The most common activity I use Facebook for is to see what people are up to.I like to look through friends'photo albums to see where they've been and who they're with.It's also a nice way to message friends casually.1 created a Facebook group for a certain club,so I just send out messages to the group when a meeting or event is coming up.
62.F
Jane's description:When Facebook was first started,everyone in my age wanted to be on it.The first version didn't have any of the fancy things-we could just message,play poke and befriend.It was too Hat.When they started to add new features like the wall,photo albums,video capabilities,and groups,people became more interested.But then Facebook took it too far.Now I find Facebook has quite a few useless features'prefer an older version of just the basics-messaging,walls,photos-and groups.
63.D
Jane's description:I don't add anything too personal to my profile.My only concern is that friends can post pictures of me that I don't want to share.I download them but they will still be on the Internet.I don't think that's a good idea.I think when you don't want a photo to be shared,it should be deleted from the photo album.
64.E
Jane's description:It wouldn't bother me one bit.It's the same as any other recommendation method.I think it's a good place to sell/buy.You see your friends are into it,so you feel the connection right there-it seems like a great time to make a purchase.If Facebook had this service setup,people could just go on to see what new songs their friends are listening to-one click and they can purchase the songs on music websites,or rent new movies on movie websites etc.
65.C
Jane's description:If Facebook keeps trying to stick in useless applications to attract advertisers,it may sink in the future.But if it allows users to go to music or movie websites directly from their friends profiles,it may become the new social networking search engine that people use to look through their friends stuff when they need advice about what to buy.If they include a feature like favorite stores to shop at,they will definitely expand on the possibilities.
