托福语法之副词修饰动词

　　例如：You can’t possibly arrive there on time. (谓语动词)

　　It’s inconvenient to contact him directly. (不定式中的动词)

　　Her composition is frequently referred to as original. (被动式)

　　改错题中常误用形容词修饰动词，要注意识别

　　例题：

　　(1)

　　In the United States， sleds for recreation were first produced commercial in the 1870’s or thereabouts.

　　应改为：commercially

　　解释：形容词commercial不能修饰谓语动词producehttp，需改为副词

　　(2)

　　According to anthropologists， the earliest ancestors of humans that stood upright resembled chimpanzees ----， with sloping foreheads and protruding brows.

　　(A) facially

　　(B) their faces

　　(C) having facial

　　(D) they had faces

　　答案：A

　　解释：resemble一词是本句的谓语动词， 已有了宾语chimpanzees， 之后需要的只可能是用来补充说明的非谓语， B、D可先排除; facial是形容词， 不能作have的宾语， 因此C肯定不对; A是副词， 恰好修饰动词作状语
