conj.虽然;尽管;即使。引导让步状语从句。
Although/Though it was so cold,he went out without an overcoat.尽管天气很冷,但他还是没有穿大衣就出去了。
【注意】　although=though用作连词,意为“虽然,尽管”,这两个词都不能与but连用,即用了although/though就不能再用but。不过although可以与yet/still一起使用。
尽管他身体不好,但是他工作很努力。
正:Although/Though he is in poor health,he works hard.
正:He is in poor health,but he works hard.

☆教材解读☆
1….but we were surprised that ninety percent of them use the Internet every day.
“be surprised + that从句”意为“……很惊讶/吃惊”。be surprised at sth.意为“对某事感到惊讶”; be surprised to do sth.意为“对做某事感到惊讶”。
I’m surprised that you are the only one to think in that way.我奇怪,你是唯一那样想的人。
I was surprised at his answer.我对他的回答感到吃惊。
【辨析】　to one’s surprise,in surprise,be surprised at
(1) to one’s surprise是“令人惊奇的是……”,surprise是名词,one’s指形容词性物主代词或所有格,to one’s surprise相当于“主语+ be+ surprised”,surprised是形容词。
To his surprise he found the girl was blind.
=He was surprised to find the girl was blind.令他惊奇的是,他发现这个女孩是个盲人。
(2) in surprise是“惊奇地”,是副词性短语,用来修饰动词,一般放在所修饰的动词后面。
The two girls looked at each other in surprise.那两个女孩惊奇地相互看着。
(3) be surprised at是“对……感到惊奇”,表示主语(一般是人)对某事或某物惊奇,surprised可以被very,too等修饰,作表语或定语。
We are very surprised at the news.听到这个消息我们很诧异。
2.The answers to our questions about watching television were also interesting.
此句的基本意思是The answers were also interesting.主语The answers为复数,故谓语动词使用were。
【注意】　本句中answer和question两个名词后的介词搭配。表示“……的答案”时,answer后要用介词to,这是一种固定搭配。
There’s no easy answer to this problem.这个问题没有简单的答案。
Do you know the answer to question number two 你知道第二个问题的答案吗
3.It is good to relax by using the Internet or watching game shows…
◆It is/was +adj.(for sb.)+ to do sth.对某人来说去做某事是……的。
It is easy for me to learn English well.学好英语对我来说很容易。
