(2)完成句子
①警察到处搜捕他。最终他被抓住了，现在警察正在对他进行搜身。
the police him everywhere. he was caught at last and now the police are him.
②显然，已经有人搜过他的房子——那本书不见了。
his house had clearly been and the book was missing.
答案及解析：(1) 选a。in search of为介词短语，意为“寻找”，符合句意。b、d两项动词形式不正确；无c项search of这种搭配。故选a项。
(2) ①searched for；searching ②searched
2. belong to 属于；是……的成员；是……的一部分
belong vi. 应被放置在，应处在（某处），适合在某处。此时，不与to连用，后面通常跟副词和其他介词短语。
belongings n.财产；所有物；行李
ps:belong to不用于进行时态和被动语态中。to 为介词，其后接代词、名词类短语及从句，表示所归属的对象。
who does this watch belong to? 这块表是谁的？
she lost all her belongings in the earthquake. 她在地震中失去了所有的财产。
i don’t really feel i belong here. 我感觉我并不适合待在这个地方。
单项填空

a. belonging b. belonged
c. belonging to d. belonged to
答案及解析：选c。belong to 在句中作定语，无被动语态和进行时态，必须和to连用。
