13.In 1983,there were only 200 computers connectedto the Internet.

分析 在1983年,只有200臺電腦能夠連上網(wǎng)絡

解答 答案:connected.
分析句子結構可知,本句中computers后面缺少一個定語,根據(jù)短語be connected to 把…連上可推斷,應該使用過去分詞短語作定語.
be connected to與 be connected with 的區(qū)別:
be connected to 把…連上.
Please connect the computer to the Internet.請把電腦連上互聯(lián)網(wǎng).
be connected with 把…與…連接起來.
It serves as a bridge which connects the mainland with the rest of the world.它是連接祖國大陸與世界其它地方的橋梁.

點評 首字母填空題考查的是詞匯的記憶和運用能力,平時要注意積累和運用.同時還要注意提示字母.

2.As you are probably aware,the latest job markets news isn't good:Unemployment is still more than 9percent,and new job growth has fallen close to zero.That's bad for the economy,of course.And it may be especially discouraging if you happen to be looking for a job or hoping to change careers right now.But it actually shouldn't matter to you nearly as much as you think.
That's because job growth numbers don't matter to job hunters as much as job turnover data.After all,existing jobs open up every day due to promotions,resignations,terminations (終止) and retirements.In both good times and bad,turnover creates more openings than economic growth does.Even in June of 2007,when the economy was still  humming along,job growth was only 132,000,while turnover was 4.7million!
And as it turns out,even today-with job growth near zero-over 4million job hunters are being hired every month.
I don't mean to imply that overall job growth doesn't have an impact on one's ability to land a job.It's true that if total employment were higher,it would mean more jobs for all of us to choose from (and compete for).
But what often distinguishes those who land jobs from those who don't is their ability to stay motivated.They're willing to do the hard work of identifying their valuable skills; be creative about where and how to look; learn how to present themselves to potential employers; and keep going,even after repeated rejections.
So don't let the headlines fool you into giving up.Four million people get hired every month in the U.S.You can be one of them.

41.The author tends to believe that high unemployment rateA.
A.should not stop people from looking for a job
B.prevents many people from changing careers
C.deprives(剝奪)many people of job opportunities
D.does not mean the U.S.economy is worsening
42.Most job openings come fromB.
A.job growth 
B.job turnover
C.improved economy
D.business expansion
43.The underlined word"humming"in Paragraph 2probably meansD.
A.falling      B.satisfying     C.disappointing      D.growing
44.What does the author say about overall job growthC?
A.It gives a ray of hope to the unemployed.
B.It increases people's confidence in the economy.
C.It doesn't have much effect on individual job seekers.
D.It doesn't mean greater job security for the employed.
45.What is the key to landing a job according to the authorA?
A.Persistence (堅持).B.Intelligence.
C.Education.D.Experience.

Dear editor,
I would like to recommend that we hold an English festival which all of us students can take part in.(希望參與的活動)
As far as I am concerned,English festival will contribute us a lot.Firstly,holding English festival can enrich students'life.They can learn different customs and cultures of English-speaking countries.It will be more interesting and lively than we learn in class.Secondly,I think English festival will be a good platform for students to display their talents in English and thus give those students more interest and confidence in learning English.(推薦該活動的理由)
I suggest that the English festival should include various activities.For example,we can have an English party in which students can give English songs,speeches and so on.We can also have an English debate辯論 about some interesting topics.All in all,I hope that the English Festival can help us students learn more about English culture and can make our after-class life more colorful and meaningful.(對此項活動的建議)
