【正确答案】 C

【答案解析】考查动词辨义。look看起来(可作系动词，后跟as if/like等，但不能直接跟形容词)；see看见，明白(不能作系动词，其后直接跟宾语)；feel觉得，感觉(可作系动词，后跟形容词)。feel close to是习惯搭配，指“觉得与…很亲近”。

【正确答案】 A

【答案解析】考查代词用法与句型。由后面的to have．．．可以看出，这一不定式实际上是句子的真正主语，因此填入的代词应作形式主语，故只能用It。其余两项填入都造成句意不通。

【正确答案】 C

【答案解析】考查副词形式。some times是词组；指“多次”，其中time是名词；sometime只用于将来时态，指“将来某个时候"；sometimes则指“有时，偶尔”。本句用的是一般现在时态，因此应选[C] 。

【正确答案】 C

【答案解析】考查形容词用法。surprised用于人，指人“感到惊讶的”；surprising用于物，指事物“令人惊讶的"；surprise用作动词或者名词。本题主语是事物it，且空格前有系动词，因此选[C] 。

【正确答案】 A

【答案解析】考查助动词和一致性。由句子结构与选项可知这里是一个省略从句，应填入一个助动词，代替前一句话从句中的谓语动词have，因此助动词只能用do，选[A] 。

【正确答案】 B

【答案解析】考查上下文关系。由上下文文意可以看出，“别人关心你”只能是使“你更好地关心自己”的一个条件，而不能是原因，前后也没有转折关系，因此选引出条件的连词If。
