例句精讲

　　The effects of the Internet on our lives

　　1.When people are in need of information,from current affairs and weather forecasts to travel packages and academic research,the Internet is now the first place that many people turn to.

　　从时事新闻、天气预报到包价旅游、学术研究，当人们需求信息时，因特网现在已是许多人的首选。

　　【巧解句构】 本句是一个复合句，首先是由when引导的时间状语从句。在从句中又包含一个定语从句that many people turn to 修饰限定the first place。

　　【要点剖析】 1)固定搭配in need of 意思是"需要"。

　　2)turn to意思是是"求助于"。

　　【联想发散】 关系代词that和which指物时，往往可以互换，但下列情况多用that:

　　1)特殊先行词后，如先行词是不定代词all,much,little,few,none,something,anything,nothing,

everything;先行词是序数词、最高级或被序数词、最高级，或被any,the only,the same等修饰时。

　　2)关系代词在限制性定语从句中作表语;主句以here,there,which或who开头;先行词指人和物。

　　2.With the touch of a button or the click of a mouse,a student can acquire knowledge from the information held in the largest libraries and museums in the world,whether he or she lives in a small village or downtown in a big city.

　　无论是住在小村庄，还是住在大城市的市中心，学生们只要敲击一下键盘按钮或者点击一下鼠标，就可以获得世界上最大的图书馆或博物馆中所储存的信息。

　　【巧解句构】1)本句是由whether引导的条件状语从句。

　　2)With the touch of a button or the click of a mouse是伴随状语。held in the largest libraries and museums in the world是后置定语，也可以表示为which/that is held in the largest libraries and museums in the world。

　　3.They claim that the Internet is useless and that using the Internet is a waste of time.

　　他们宣称因特网没有用处，使用因特网是浪费时间。

　　【巧解句构】 1)动词claim后面接两个以that引导的宾语从句，第二个从句中that不省略。

　　2)a waste of意思是"......是浪费的"。

　　Researching on the Internet

　　When you are finished,you should always attach a list of the sites you got your information from.This way,a teacher can check them,and an interested friend can also read what you read.

　　完成报告时，你应该记得附上你获得信息的网址清单，这样，老师就可以核对这些网址，有兴趣的朋友也可以阅读一下你所阅读过的内容。

　　【巧解句构】 1)句中的时间状语When you are finished 相当于When you have finished writing your report。

　　2)you got your information from是定语从句修饰限定a list of the sites。

　　3)what you read是宾语从句。
