2019屆中考英語重點語法總復習教案
真實條件句,如:if it rains tomorrow, we won’t go on a picnic.
非真實條件句是虛擬語氣的一種,表示與事實相反,如:if i were you, i would go with him.
so/as long as只要 由as (so) long as, in case引導。
so long as you’re happy, it doesn’t matter what you do.只要你高興,你做什么都沒有關系。
you may borrow my book as long as you keep it clean.只要你保持書的清潔,你就可以把我的書借去。
take your umbrella in case it rains.帶著你的傘吧,以防下雨。
10. (a) few + 可數名詞, (a) little + 不可數名詞
a few / a little 為肯定含義,還有一點
few / little 為否定含義,沒有多少了。
he has a few friends. 他有幾個朋友。
he has few friends. 他幾乎沒有朋友。
we still have a little time. 我們還有點時間。
there is little time left.幾乎沒剩下什么時間了。
although he 's wealthy,he spends___ on clothes.
a. little b. few c. a little d. a few
答案: a. spend所指的是錢,不可數,只能用little或 a little. 本句為although引導的讓步狀語從句,由句意知后句為否定含義,因此應用little表示幾乎不。
固定搭配:
only a few (=few) not a few (=many) quite a few (=many)
many a (=many)
many books were sold.
many a book was sold. 賣出了許多書。
