unit 5 第二课时
ⅰ.语法填空
1．the fact ________ a planet exists outside our solar system encourages the hope ________ other solar systems exist.
答案：that; that 此句的主干是the fact encourages the hope.。空格处引导同位语从句，从句补充说明fact, hope的内容，空格处不在句中充当任何成分，故用that。
2．we hadn't settled the problem ________ would be sent to take charge of that chain shop.
答案：who who引导同位语从句，该从句进一步解释problem的内容，who在从句中作主语。
3．recently he has been always having an idea ________ he will use the pocket money to buy flowers for his mother's birthday.
答案：that that引导同位语从句，该从句补充说明idea的内容，that在从句中仅起连接作用。
4．we all agree to his suggestion ________ we organize a football club.
答案：that 句意：我们都同意他提出的我们组织一个足球俱乐部的建议。that引导同位语从句，该从句用来解释suggestion的具体内容。
5．the committee made the order that more buildings ________(build)．
答案：(should) be built order表示“命令”，其后的同位语从句要用虚拟语气，从句谓语要用“should＋动词原形”，should可以省略。
6．they all are now upset because they have no idea at all ________he has gone.
答案：where 句意：他们很担心，因为他们完全不知道他去哪儿了。where引导同位语从句，且在从句中作地点状语，同位语从句应用陈述语序。
7．although the family is very poor now, the members of it all hold the belief ________ their living conditions will improve.
答案：that 句意：尽管这个家庭现在很贫穷，但是所有的家庭成员都坚信他们的生活条件会提高。本句中同位语从句的引导词不在从句中充当任何成分，故用that。
8．she has some doubt ________ her advice is of great value to us.
答案：whether 句意：她有些怀疑她的建议对我们是否有帮助。doubt用在肯定句中，后面的同位语从句用whether来引导。
9．it was the fact ______ he had to find another job ________ made him worried much.
答案：that; that 句意：他不得不去找另一份工作，这让他很担心。第一空用that引导同位语从句，该从句对fact的内容进行解释；第二空考查强调句型中的that。
10.mr. frank asked me a question ________ i could go with him to ________ he called the treasure house the next week.
答案：whether; what 第一空用whether引导同位语从句，该从句解释question的内容；第二空用what引导宾语从句，what作called的宾语。
