根据句意, 用括号内所给单词的适当形式填空。
【小题1】Two ninths (nine)of the students in our school suffer from stress.
【小题2】All parents love their children, and my parents love ninths （they）,too.
【小题3】The students looked at their teacher theirs (hope) and were very excited.
【小题4】Because of the warm weather children feelhopefully (sleep) in class than before.

解析：【小题1】此题考查分数的表达方式，根据语境可知考查的是九分之二的表达方式，因分子是二，故序数词的后面要加s.【小题2】此题考查名词性的物主代词，因给的单词是they故用theirs.此句的含义是所有的父母都疼爱他们的孩子，我们的父母也是。【小题3】此题考查副词，根据语境可知此句的含义是孩子们满怀期望的看着老师，因修饰动词故用副词形式hopefully。【小题4】此题考查系表结构，因有比较的含义故用形容词的比较近，故选sleepier.
