这个look是连系动词还是实义动词
 
这个look是连系动词还是实义动词？其后该接形容词还是副词？
a. He looks __________. http://yingyu.chazidian.com
b. He looked __________ at his broken car.
A. sad，sad             B. sadly，sadly             C. sad，sadly              D. sadly，sad
此题应选 C。这里要分清look用作实义动词和连系动词的两种不同用法。从句意和结构上看：a句中的look 是连系动词(句意为：他看起来很伤心)，所以此句用形容词sad作表语。b句中的look是实义动词(句意为：他伤心地看着他的破汽车; 另外句子中的介词at也给我们一定的提示)，所以此句用副词sadly作状语。
以下各例也涉及实义动词和连系动词的两种用法：
1. a. Hearing this，she felt _________.

A. happy，strong                           B. happily，strongly
