I. 内容全解

1．It then became possible for universities to use the system as well.

然后大学里也可以运用这套系统。

这是一个it作形式主语的句型，后面的动词不定式作真正的主语。这类结构有：

（1）h is／seems／feels…＋adj.＋to do sth.

It's hard to translate this sentence into English.

把这个句子译成英语很难。

It seems easy to deal with him.

跟他打交道好像挺容易。

（2）It's＋n.＋to do sth.

It's a mistake to do it in this way.

这样做是错误的。

It's a pleasure to be with you.

跟你在一起很高兴。

（一句多译）在这儿见到你真意外!

1.It's great surprise to meet you here!

2.It's very surprising to meet you here!

3.I'm very surprised to meet you here!

（3）It＋动词短语＋to do sth.

It needs hard work to finish the job.

做完那项工作需要艰苦劳动。

It requires patience to teach children.

教育孩子需要耐心。

（4）在这类句子结构中，不定式的逻辑主语通常可在特定的情景中看出，也可用介词for或of引出。

It's impossible for him to go alone.

他一个人去是不可能的。

It's kind of you to say so.

谢谢你这样说。

［辨析］It's…for sb. to do与It's…of sb. to do

句型It's＋adj.＋for sb. to do中，it为形式主语，for，sb. to do是真正的主语，使用这一句型只表明不定式行为的特点，而不表明sb.本身的特点，常见的此类形容词有easy，difficult，hard，important，necessary，expensive，impossible等。

句型It's＋ adj.＋of sb. to do中，it为形式主语，of sb. to do 是真正的主语。使用这一句型意在对sb.及其所做的行为进行评价，

此类形容词有good，kind，nice，wise，wrong，clever，brave，honest 等。另外，后一种句型可以进行下列句型转换：

It's stupid of you to make such a mistake.

＝You are stupid to make such a mistake.

而前一种句型则不能这样转换：

It's impossible for him to go alone.不能转换为：

He is impossible to go alone.

2．NSFNET became known as the Inter—Network，or "Internet". NSFNET作为“内部网络”或者“因特网”而闻名。

become／be known as被称作；被认为

He is known as a fair judge.

他被认为是一位公正的法官。

These chocolate bars are known as something else in the U.S.，but I can't remember what.

这种巧克力棒在美国有别的叫法，但我记不起叫什么来着。

1.be known for 因……面著名

2.be known to 为……所知

3.It's well known that 人们都知道

He is known for his frankness.

他以坦率著称。

I don't think he's known to anybody here.

我认为这里谁也不认识他。

It is well known that Edison invented the electric lamp. 人们都知道是爱迪生发明了电灯。

［比较］be famous仅表示“出名”，后跟as或for，相当于be known as／for，但不能用于It's…that的结构。

3．At the moment，about 80 percent of web traffic is in English，but this percentage is going down.

目前，大约有80%的网络用英语，但这个百分比正在下降。

at the moment＝at the present time；now

此刻；现在

The number is engaged at the moment. Try again later.

这个号现在占线，随后再试试吧。

百分数的表达法

百分数由“基数词＋percent (per cent ) 构成”。如：53%读作fifty —three percent，应注意的是percent不能用复数形式。若百分数部分用作主语，其谓语动词要依其后的名词意义来决定。如：

About sixty percent of the apple is bad.

这个苹果约60%坏了。

About sixty percent of apples are bad.

这些苹果的约60%坏了。

I think it's ninety percent probable.

我想有90%的可能。
