2022年4月山东自考英语(一)复习（46）

how引导的是一个宾语从句。我们很熟悉的是that引导的宾语从句，而且that常常可以省略。如：We must remember (that)things are easier said than done. (我们必须记住事情都是说起来容易，做起来难。)

用连接代词或副词引导的宾语从句我们也应弄清楚。

provide是一个常用单词，通常可以有如下用法：provide sth. to/for sb.; provide sb. with sth.; provide sb. sth.;provide that…，在前一个单元中，我们已对provide一词有过讲解

6.He was then able to follow the doctor's instructions on how to care for the patient.

句子中的on意思为“关于;有关”，可用about替换

care of 在句子中的意思是“照顾”，可用attend; look after替换。

care for 还可以解释为“担心”，“介意”，“愿意”，可用about替换for.

1)He doesn't care about/for his clothes. (他不讲究衣着。)

2)The old lady cared much for her daughter's safety. (老太太非常为女儿的安全担心。

7.The most common use of telecommunication satellites，however，has been for transmitting telephone calls.however

在本句中做副词用，意思相当于but.但是however和but在用法上是有差异的。however不放在句首或句末时，前后通常都加逗号，而but则不用。请看例句：

1)It is not，however， the only answer to the question. (然而，这不是问题的唯一答案。)

2)I am sorry，but I won't be able to come this time. (很报歉，我这次不能来了。)

8. Telecommunication can make information from around the world available to use quickly and easily， but some people worry that this may be a risk to our privacy.

available是一个形容词，意思是“可得到的;可用的;有效的”。

1)I am sorry those shoes are not available in your size. (很报歉，那些鞋没你的尺码。)

2)If I am not available when you call， leave a message. (你打电话来时如果我不在，请留个言。)

9.We can prevent this from happening by carefully controlling the new technology.

prevent…from…意思为“阻止…发生”，也可用stop…from…或keep…from.From在前两个短语中可被省去。

Nothing can prevent him (from)going there.(什么也阻止不了他去那儿。)
