Ⅲ.单元语法精讲
、1.A
点拨:本题用结构分析法。句意为“她还不够强壮,不能去爬山。”be enough to do sth.是固定结构,“足够……做某事”。
2. A点拨:本题用语法判定法。 enough修饰形容词时,放在形容词后,可知B是错误的。 big enough too big太大;too small How big可推测出是大的,排除D;把C项代入句中理解, too.……而不能……”,意为“太大而不能容下”,不符合逻辑。故选A。
3.A点拨:本题用语法判定法。句意:这部电影不够有趣。他中途看着看着就睡着了。 enough修饰形容词或副词时,要放在被修饰词的后面,故排除了B和D;inter ested interesting“有趣的”,主语为物。本句的主语是 this mov-ie,故选A。
4.D点拨:本题用句意理解法。句意:这家餐厅是足够大的,能容纳300人。副词 enough修饰形容词时需后置,故选D
5.C点拨:not+ad.+ enough to do相当于too..to.so.that+表示否定的从句,故选C
6.D点拨:本题用结构分析法。由“all the
tennis fans in China know her"可知用sothat,连接两个句子。所以选择D
7.D
8.C点拨:本题用语法判定法。 tired是形容词,walk为动词原形,所以排除B、D两项;又 enough修饰形容词时要放在其后,所以只能选C。句意为:这位老人说他太累了,不能再走了。
9.A点拨:本题用结构分析法。选项D不构成固定搭配,首先排除。tooto.中to后接动词原形,本句为从句的形式,故排除。 such nice girlso nice girl,故选A。
10.A
点拨:题意:对汤姆来说,这袋大米太重,他搬不动。让我们去帮帮他。oto为固定搭配,意为“太……而不能…”
