题目内容
Dolphins are rare, but sometimes it is possible _______ them near here.
| A．to see | B．to look | C．seeing | D．looking |
A
解析试题分析：句意：海豚很稀少，但有时在这儿附近看到它们也是可能的。根据固定句型It is possible to do sth做某事是可能的，由此排除C和D。look为不及物动词，一般不直接跟宾语；see为及物动词，表示看的结果，直接跟宾语，如：He looked at the blackboard but saw nothing他朝黑板看去，但什么也没有看到。故选A。
考点：考查固定句型和动词辨析。
