高一unit 2 學案(人教版高一英語上冊學案設計)

1. time構成的短語

①for the first time第一次，初次，用作時間狀語。

e.g. He came to China for the first time.

②the first time 第一次，首次，用作連詞，引導時間狀語從句。

e.g. The first time I met him, he was helping friends with their chemistry.

③當句子裏有This/It/That is the first/second/third/last/best… time結構時，要用現在完成時。

e.g. This is the third time you’ve asked me the same question.

④time作次數解時爲一可數名詞。

He failed his driving test five times.

I have told you not to be late a dozen times.

2. There you are! 行了，好了。這是一句表示一種事情告一段落或有了最終結果的用語。例如：

There you are! Then let’s have some coffee.

除此以外，還可以表示“瞧，對吧（果然如此）”的語氣。例如：

There you are! I knew we should find it at last. 對吧！我就知道我們最終能找到的。

3. must表示推測,作“一定，肯定”解，只能用在肯定句中。在否定句中應用can’t。 may和 might表示推測時，意思是“可能”。否定形式也是can’t。may not 或might not 表示“可能不”。mustn’t 表示“堅決不許做某事”。

e.g. (1) This must be your room.

這一定是你的房間了。

(2) They must be waiting for us. Let’s hurry up.

7. a number of和the number of

e.g. A number of students are waiting outside the school gate.

besides意思是“除……之外（還有）…..”,其內涵是“加上”。

e.g. Do you know other language besides German?

Li Lei also went to the park besides you.

except意思是“除……之外”，其內涵是“減去”。從 整體中排除。它前面常有all, every, any, no及其複合詞。

e.g. Everyone is at school today except Lin Tao.

The students go to school every day except on Saturday and Sunday.

except for 是在說明整體的基本情況後，再對細節加以糾正，其後一般加名詞。

e.g. Your composition is well-written except for some spelling mistakes.

except that (wh-) 其後需加從句，用來表示理由或細節，修正前面所說的情況。可以與except for互換。

e.g. Your composition is well-written except that there are some spelling mistakes.

9. stay up 不睡覺，熬夜，不倒塌。

(2) Everyone in the town knew him , so we had no difficulty in finding his house.

城裏人人都認識他，所以，我們毫不費力地找到了他的家。

如果difficulty後接名詞時，名詞前面要加with，即have difficulty with something。同樣的用法還有：be busy doing something, be busy with something。help somebody (to) do something, help somebody with something。

另外，difficulty還可以用trouble或problem替換。

about（某情況）發生

Sometimes it is hard to tell how a quarrel comes about.

有時候很難解釋爭吵發生的原因。

or less或多或少

e.g. I’ve more or less finished reading the book.

It took more or less a whole day to paint the ceiling.

類似的短語還有：sooner or later, this or that, here and there

Computer is widely used in China nowadays.

同樣的區別還有：high, highly, deep, deeply, close, closely, late, lately
