中考英语语法必备定语从句易错易混点 易错点二:固定句式出差错。例 3. Mary is so lovely a girl as everybody loves her. 例 4. Mary is so lovely a girl that everybody loves. 析:例 3 中的 as 应改为 that ;例 4 中的 that 应改为 as . so…as 或 so…that 为固定句式,前者为 as 引导的定语从句, as 在定语从句中作宾语或主语,如例 4 ;后者为 that 引导的结果状语从句,该从句的成分是完整的,不缺少主语或宾语,如例 3 .类似的固定句式还有 the same… as (that) , such…as , as…as 等。 易 错 点 三 : 主 谓 不 一 致 。 例 5. Tom is one of the students who likes swimming. 例 6. Tom is the only one of the students who like swimming. 析:例 5 中的 likes 应改为 like ;例 6 中的 like 应改为 likes .在“ one of + 复数名词 + 定语从句”结构中,定语从句的先行词是复数名词,故谓语动词要用复数形式,如例 5 ;在“ the (only) one of + 复数名词 + 定语从句”结构中,先行词是 one ,而不是复数名词,故谓语动词要用单数形式,如例 6 . 易错点四:与强调句型及其他句型的混合。例 7. Was it in the shop that you bought the recorder that you lost your pen? 例 8. You’d better make a mark at where you have any questions. 析:例 7 中第一个 that 应改为 where ;例 8 中应去掉 at .例 7 为带有定语从句的强调句, you bought the recorder 为定语从句,其引导词应用 where ,后面第二个 that 才是强调句中的 that ,此句可还原为: You lost your pen in the shop where you bought the recorder .例 8 为 where 引导的地点状语从句。 易错点五:对先行词概念不明确。例 9. It this library that you visited yesterday? 例 10. Is this the library where you visited yesterday? 析:例 9 中应在 library 后加 the one ;例 10 中的 where 应去掉或改为 that 或 which .在例 9 中, this library 是主语, is 是谓语, that 引导的是定语从句,但没有先行词,故应补加先行词;在例 10 中, the library 是先行词,定语从句缺少宾语,故应用 th...
