1．_______________(钟声响了) and we realized it was already two o’clock in the afternoon.
　　2.Finding it difficult to _______________(适应那里的气候)，he decided to move to the north.
　　3.He asked the teacher to____________________(解释得更详细一些)。
　　4．___________________________(与成年人学习外语相比) children do not have good conditions, but they can master mother tongue completely.
　　5.________________(就外表而言)，Jack and his younger brother have little in common.

　　答案：
　　1. The clock struck
　　时钟报时用strike,而不用ring.电话铃响了一般用ring.
　　2. adapt to the climate there
　　adapt to 有“与……相适应”的意思，还可以用“be accustomed to ”或“be adjusted to”来表达类似的意思。注意这些“to”
　　后面一定要跟名词或动名词。
　　3. explain the word in greater detail
　　“explain the word in greater detail”即“详细解释某事”的意思。
　　4. Compared with adults learning foreign languages
　　此句考查分词的正确使用，它的主语是children,与adults相比，与compare是动宾关系，所以要用表示被动关系的过去分词形式。
　　5. As far as the appearance is concerned
　　“as far as something is concerned”表示“就……而言”，相似的短语有“as something referred”,表示就某事物的某方面作说明。
