Unit 5 Section Ⅱ
Ⅰ.语法填空
1．The fact __that__ a planet exists outside our solar system encourages the hope __that__ other solar systems exist.
解析：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 __who__ would be sent to take charge of that chain shop.
解析：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 __that__ he will use the pocket money to buy flowers for his mother's birthday.
解析：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。
