　　答案：to sell　have no alternative but to do ... "除......之外别无选择，只能做......"。

　　3．It is generally ________(assume) that stress is caused by too much work.

　　答案：assumed　It is assumed that ... "普遍认为......"。

　　4．We should bear in mind that teamwork is of great ________ (significant) to both our society and ourselves.

　　答案：significance　of great significance＝very significant "意义重大/非常重要"。

　　5．Once ________(arrest), he was likely to betray everything to the police.

　　答案：arrested　arrest与其逻辑主语he之间为被动关系，故用过去分词在句中作状语。
