二、重点与难点分析

    Lesson  49

⒈I’m doing a word puzzle in this newspaper. 我正在猜报纸上的字谜。

puzzle意为“谜”，do a word puzzle or do a puzzle in words意为“猜字谜”。

这里的puzzle是名词，作“难题”，“难以解释的东西”讲。

例如：The murder case was a puzzle to the police. 这桩谋杀案对警察局来说是一个难题。

puzzle也可以作动词，意为“使人迷惑不解”。例如：

The murder case continued to puzzle the police.

这桩谋杀案仍使警察局迷惑不解。

⒉It must be him! 那肯定是他！

    情态动词must主要指“肯定”和“禁止”，前者用于肯定句，表示推测，后者用于否定句，表示禁止。例如：

    My father must be watching TV now.

    我爸爸现在肯定在看电视。

    She must be in the classroom.

    她肯定在教室里。

    You mustn’t smoke in public places.

    公共场所禁止吸烟。

    Lesson  50

⒈When he was a young boy he used to ask lots of questions…

   他小时候常常问许多问题…

    used to do sth. 意为“过去常常做某事”

    be used to doing sth. 意为“习惯于做某事”

    be used to do sth. 意为“被用来干什么”

    例如：I used to drink coffee in the evening, but now I am used to drinking coffee in the morning.

           过去我常常晚上喝咖啡，但是现在我习惯于早上喝咖啡。

           Computers can be used to do a lot of work nowadays.

           如今计算机可用来做许多事。

⒉By the time he was fourteen years old, he had learned maths all by himself.

  到十四岁时，他已经自学了数学。

by与时间名词连用时表示“到某时为止”，“不迟于…(时间)”

当by后接将来时间时，句子时态用一般将来时或将来完成时；当by后接过去时间时，句子时态用过去完成时。当by后接现在时间时，句子时态用现在完成时。

    例如：

    My mother will be back by 5 o’clock this afternoon.

    今天下点五点以前我妈妈就回来了。

    We had learned 2000 English words by the end of last term.

By now, several bridges have been built over the Changjiang River.

到目前为止，长江上已经建了好几座桥。

⒊He found it hard to get along with the other boys.

   他觉得很难与别的孩子相处。

在此句中，it为形容宾语，hard为宾语补足词，真正的宾语是不定式短语to get along with the other boys.

在一个含有复合宾语（即：宾语+宾补）的句子中，当宾语是不定式短语或从句时，由于不定式短语或从句较长，所以常使用it作形式宾语，而把真正的宾语置于句尾，以保持句子的平衡。例如：

I found it difficult to learn French well.

我觉得学好法语是很难的。

They kept it quiet that he was dead.

对于他的死他们保密。

⒋All through his life Einstein was content to spend most of this time alone, although he married twice and had lots of close friends.

   虽然爱因斯坦结过两次婚，而且有很多亲密的朋友，但是在整个一生中，他还是愿意独自度过他的大部分时光。

    content adj. 满足的；满意的；愿意的

    be content with sth. 对…感到满意

    be content to do sth. 愿意做某事

    She is content with her present job.

    她对目前的工作很满意。

    I am always content with very little.

    我总是很容易满足。
