【題目】下圖為“某地區(qū)地質(zhì)構(gòu)造圖”。讀圖回答下列問(wèn)題。

(1)判斷圖中F3 F4的地質(zhì)構(gòu)造并說(shuō)明理由。

(2)該地區(qū)的主要地形是________。F1F2、F3F4形成之前,該地區(qū)是一個(gè)完整的________構(gòu)造。

(3)①分析圖中河流的成因。該河流沿途居民點(diǎn)很少或居民點(diǎn)規(guī)模很小,主要原因是什么?

(4)從地質(zhì)構(gòu)造條件考慮,該地區(qū)是良好的________構(gòu)造。

【答案】(1)斷層。 F3F4兩側(cè)的同一巖層發(fā)生斷裂位移。

(2)山谷 向斜

(3)巖層斷裂后遭受侵蝕而成。 該河沿線多急流瀑布,不利于航運(yùn);沿?cái)鄬影l(fā)育的河流,其河水沿?cái)鄬用媪魇,?dǎo)致其水量小,地表水資源不足。

(4)儲(chǔ)水

【解析】本題組以地層和等高線圖為載體,考查地質(zhì)構(gòu)造的判讀、形成原因及其運(yùn)用,主要考查考生獲取和解讀地理信息、論證和探討地理問(wèn)題的能力。

(1)讀圖可知,F3F4一線兩側(cè)地層不連續(xù),說(shuō)明巖層發(fā)生了位移,其地質(zhì)構(gòu)造為斷層

(2)根據(jù)等高線圖,該地區(qū)等高線凸向高值,其地貌類型為山谷。在斷層形成之前,根據(jù)該地區(qū)巖層的新老關(guān)系,中間巖層新、兩側(cè)巖層老,其地質(zhì)構(gòu)造為向斜。

(3)河流位于斷層地帶,其成因應(yīng)為巖層斷裂后再遭受外力作用而成。該河流沿線居民點(diǎn)少或者小的原因,分析該地區(qū)斷層和等高線特點(diǎn)對(duì)航運(yùn)和水源的不利影響。

(4)根據(jù)第(2)題該地區(qū)為向斜,屬于良好的儲(chǔ)水構(gòu)造。

【題目】Facebook users may feel socially successful in cyberspace(虛擬空間) but they are more likely to perform poorly in exams,according to a new research into the academic impact of the social networking website.

About 83% of British 16 to 24yearolds are thought to use social networking sites such as Facebook,MySpace and Bebo(視頻博客),to keep in touch with friends and organize their social lives.

“Our study shows people who spend more time on Facebook spend less time studying,”said Aryn Karpinski,a researcher in the education department at Ohio State University.“Every generation has its distractions,but I think Facebook is a unique phenomenon.”

Karpinski and a colleague questioned 219 US undergraduates and graduates about their study practices and general Internet use,as well as their specific use of Facebook.

They found that 65% of Facebook users accessed their account daily(刷新個(gè)人主頁(yè)),usually checking it several times to see if they had received new messages.The amount of time spent on Facebook at each login varied from just a few minutes to more than an hour.

The Ohio report shows that students who used Facebook had a“significantly”lower grade point average—the marking system used in US universities—than those who did not use the site.

“It is the equivalent of the difference between getting an A and a B,”said Karpinski,who will present her findings this week to the annual meeting of the American Educational Research Association.

Some UK students have already spotted the potential danger.Daisy Jones,21,an undergraduate in her final year at Loughborough University,realized the time she was spending on Facebook was threatening her grades—prompting her to deactivate(注銷) her account.

Jones is among the few to have recognized the risks.According to Karpinski's research,79% of Facebookusing students believed the time they spent on the site had no impact on their work.

Facebook said,“There is also academic research that shows the benefits of services like Facebook.It's in the hands of students,in consultation with their parents,to decide how to spend their time. ”

1According to the passage we know that most present students like to get in touch with their friends by ________.

A. sending short messages B. chatting online

C. Facebook site D. sending emails

2The study shows that compared to ones who avoid websites,the school results of the students who use social networking sites are ________.

A. the equivalent of the difference between getting an A and a B

B. not less grades in all studies

C. more ambitious to succeed in their studies

D. just the same

3Researchers' survey aimed at students on the following EXCEPT ________.

A. their study practices

B. their general Internet use

C. their specific use of Facebook

D. their habits of living

4In your opinion,this research result will appear as ________.

A. news B. text

C. report D. essay
