III.:語法：

本單元復習英語三大從句之一的名詞性從句。首先，要清楚名詞性從句的概念、構成和分類;其次，要清楚名詞性從句引導在從句的語法作用;再次，要清楚同位語從句與定語從句和強調句型的區別。

名詞性從句是英語教學的一個重點，也是各類各級的必然考點。常見的考點有：

1.由that, if / whether, wh-疑問詞，wh-ever詞引導的名詞性從句。

2.名詞性從句的語序問題。

3.if與whether的區別。

4.替代詞it與名詞性從句。

5.名詞性從句作主語時的主謂一致問題。

6.wh-ever詞引導名詞性從句與讓步狀語從句的區別

The farmers live by _______.(farm,farming) (Which word will you choose?)

Yes,“farming” is the correct word.

Farm: an area of land, together with its buildings.

Farmland: only the land for farming.

Farming: working on the farm.

To farm : to do farm work

1).They like to eat _______. 2).They live by________.(fish,fishing)

2.work out: The FAO has worked out that up to 30% of food is lost in storage.

a)work out 一詞的“新詞義”曾經出現在2001年高考“單項真空”中，現在，可結合Lesson14的內容，試用work out的“新詞義”造句如下：

Various things have been done to increase the food supply in the world. But at first they all seemed unlikely to be of any efficiency at all. However, dozens of years have passed and most of the efforts seem to be working out far better than most of the optimistic people expected.

b)work at, work on, work out

work at和 work on都有“從事……”的意思。

在此意義上，兩者可以換用。如：

Is Tom still working at / on the new novel that he promised?

work at 還有“在……工作”的意思。如：

How long have you been working at this school?

work on 還有(激起人的感情等)“對……起作用，影響……”的意思。如：

The sight of so much suffering worked on our hearts so that we were filled with pity.

這么多受難的情景時震憾了我們的心，我們心中都充滿了同情。

work out 表示“計算出，解決(問題)”等意思。如：

Can you work out how much it costs to feed a common family?

I can’ t work out this sum.

work out 還有“想出，弄清楚(常用于否定句)”等意思。如：

We must work out a better method of saving money.

I can’t work out the meaning of this poem. 1. order的用法
