八年級英語下冊Review of units 1—3知識講解
例如:
the boy isn't a bit hungry. 那男孩一點也不餓。
the boy isn't a little hungry.那男孩非常餓。
4. besides,except,but
這三個詞都可以用來表示轉(zhuǎn)折,但是用法有所區(qū)別:
(1)except與besides 用于肯定句時,except意為“除…外(不再有)”;besides意為“除…外(還有)”:
例如:
we all passed the exam besides tom. 除了湯姆外,我們也都及格了(湯姆也及格了)
注意:
besides在句中的位置較活,可放在句首,亦可放在句中或句末;而except多放在句尾。
(2)except前幾乎總有all,any,every,no及其復(fù)合詞等詞,而besides前面可用也可不用,依句意而定:
例如:
he answered all the questions except the last one. 除最后一個問題沒答外,其余問題他都答了。
all of them went to beijing last summer besides tom. 除了湯姆外,他們?nèi)ツ晗奶煲捕既ミ^北京。
(3)except,but,besides用于否定句時,可以互換。
如:
there aren’t any other people to be considered besides/except/but you.
除你之外,其他人將不予考慮。
i didn’t look anywhere besides/except in your bedroom. 除了你的臥室外,我哪兒也沒去找。
(4)but和except都可以和for連用,構(gòu)成短語;也可跟 that 從句做賓語。
如:
l asked nothing from him but/except that he should write to me every other week.
我只要求他每兩周給我寫一封信。
you can't succeed in the exam but/except that you will work still harder.
你若不比以前學(xué)習(xí)更用功些,是不可能考上的。
二. 重點句型
1. there be …
是“某處有某人或某物”的句型表示“存在”,注意:本句型要用就近一致的原則。
另外,there be句型有一些擴展形式:there + live(lie,stand,come,go)+主語+其它。
如:
(1)once upon a time,there lived a king.
(2)there goes the bell.
(3)on the hill(there)stands a house.
注意此句:there will have a class meeting this thursday afternoon.是錯誤的。
應(yīng)將其改為:there will be a class meeting this thursday afternoon.
對there be句型中的主語提問時,無論主語是單數(shù)還是復(fù)數(shù)都用“what’s + 地點狀語?”
如:
there are five apples on the plate.→what’s on the plate?
2. too…to,so…that…和enough to do sth. 的句式在一定的情況下可以互換。
(1)在肯定句中含so … that …的復(fù)合句可以轉(zhuǎn)換成含有enough to do sth. 結(jié)構(gòu)的句子。
如:
he worked so hard that he finished the work in time.
→he worked hard enough to finish the work in time.
if your son feels well enough to watch tv by then,he’ll be fine after the game.
→if your son feels so well that he can watch tv by then,he’ll fine after the game.
