14. He _____ a visit to the factory and was warmly _____ by the workers there.
A. took, welcome B. took, welcomed
C. paid, welcome D. paid, welcomed
【陷阱】容易误选A或C。因为许多同学会模仿 come → came → come 的变化形式，想当然地认为 welcome的变化形式是 welcome → welcame → welcome。
【分析】此题第一空应填动词 paid，因为 pay a visit to（拜访）是惯用搭配，其中的 pay 不能换成take。第二空要填welcomed，因为welcome 用作动词时，其过去式和过去分词均为 welcomed，即它是规则动词。有的同学也许会问，我们不是常说 You are welcome 吗? 为什么其中的 welcome 未用 welcomed 呢？那是因为此处的 welcome 为形容词，而不是动词。
15. The boy said that the fish his mother cooked tasted ______.
A. good B. well
C. to be good D. to be well
【陷阱】几个干扰项均有可能误选。
【分析】按英语语法，连系动词后通常接形容词作表语，而不接副词，据此可以排除选项B和D。但到底是应选A还是C呢？许多同学凭感觉认为 taste to be good 似乎很通顺，于是选了C。但是，错了，正确答案应是A。原因是用作连系动词的 taste 后习惯上不接to be。如：
这棵树上的苹果味道很好。
正：The apples from this tree taste delicious.
误：The apples from this tree taste to be delicious.
类似地，feel, smell, sound 等连系动词后习惯上也不接不定式 to be。如：
你的想法听起来很好。
正：Your idea sounds a good one.
误：Your idea sounds to be a good one.
玫瑰发出香气。
正：Roses smell sweet.
误：Roses smell to be sweet.
比较：seem, appear, prove, turn out, continue 等连系动词后可以接不定式 to be，也可省略 to be。如：
She seems (to be) a little tired. 她似乎有点累。
He appears (to be) quite young. 他显得年轻。
The examination turned out (to be) quite easy. 结果考试相当容易。
The weather continued (to be ) fine. 天气仍然很好。
注：用作连系动词的 look 后能否接 to be，各语法家意见不一：有的认为可接to be，有的认为不能接 to be。为此，建议同学们以不接 to be 为宜。
