Ⅰ阅读理解
A
Surfing W1 the Internet for fun will make you a better employee， according to an Australian study．
The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive than those who do not． Study author W2 Brent Coker said，“Surfing the Internet at times helps increase an employee's attention．”
“People need to relax for a bit to get back their attention，” Coker said on the university's website．“Having a short break， such as a quick surfing of the Internet， helps the mind to rest itself， leading to P a higher total Internet attention for a day's work， and as a result， increases productivity (生产效率)，” he said．
According to the study of 300 workers， 70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours． Among the most popular surfing activities are searching for information about products， reading online news， playing online games and watching videos．“Firms spend a lot of money on software to block their employees from watching videos， using social networking sites or shopping online，” said Coker．“That's not always a good idea．”
However， Coker said the study looked at people who surfed the Internet in moderation (适度)， or were on the Internet for less than 20 percent of their total time in the office．“Those who spend too much time surfing the Internet will have a lower productivity than those without，” he said．
1．What does the University of Melbourne study mainly show?
A．People who surf the Internet are good employees．
B．Not everyone surfs the Internet for fun during office hours．
C．The Internet is becoming more and more important in people's life． D．Surfing the Internet for fun at times during office hours increases productivity．
答案：D 细节理解题。

根据第二段可知，在上班时间，偶尔浏览网络以娱乐放松自己，可以提高工作效率。

故选D项。

2．The underlined word “block” in Paragraph 4 means “________”．
A．stop B．organize
C．protect D．separate
答案：A 词义猜测题。

文章讲到公司让员工上班期间上网并休息一下，有助于他们恢复注意力，进而提高生产效率。

紧接着提到有些公司并不鼓励员工上班期间偶尔上网娱乐，
作者认为这并不总是好主意，可推知block在文中意为“阻止”。

故选A项。

3．What can we infer from the last paragraph?
A．Those who never surf the Internet have the lowest productivity．
B．Spending too much time surfing the Internet reduces productivity．
C．Most people don't surf the Internet in moderation during office hours．D．People should spend as little time as possible surfing the Internet．
答案：B 推理判断题。

根据最后一段最后一句可知，如果一个人上班期间上网放松娱乐的时间过久的话，那么他的工作效率就会降低。

故选B项。

2．recently 考查词性转换。

根据句子结构可知，此处用副词作状语。

根据句子结构可知，此处用形容词作定语。

caring “有爱心的；关心他人的”/careful “周到的；谨慎的”均符合语境。

Ⅲ 短文改错
Some day I happened to find a chat room on my QQ ， there people were chatting in English ． I tried to chat with some of them ． To my surprised ， I found the oral English of some junior students were better than me ． I asked them for advice and they told me to practise more on QQ ． But every day after that I would spend one hour practise my oral English on QQ ． Day by day I learned from many useful words and expressions ． With time went by ， I found that I could even communicate some college students freely ．
答案：
Some ①One
day I happened to find a chat room on my QQ ，ther e ②where people were chatting in English ． I tried to chat with some of them ． To my surprised ③surprise ， I found the oral English of some junior students were ④was
better than me ⑤mine ． I asked them for advice and they told me to practise more on QQ ．But ⑥So
every day after that I would spend one hour practise ⑦practising my oral English on QQ ． Day by day I learned from ⑧
many useful words and expressions ．With ⑨As time 或went ⑨going
by ， I found that I could even communicate ∧⑩with some college students freely ．
难项分析：
第五处：me→mine 考查名词性物主代词。

此处是“比我的英语口语好”之意。

mine ＝my oral English 。

第六处：But→So 考查连词。

本句与上一句之间在句意上存在因果关系，故将But 改为So 。

第九处：With→As 或went→going 考查连词/with 复合结构。

将with 改为as 可引导
一个时间状语从句，意为“随着时间的流逝”；或将went改为going，构成with复合结构，在句中作时间状语。
