1. He told me the news, believe it or not,he had earned $1 000 in a single day.
A. thatB. whichC. asD. because
你知道句中的believe it or not是什么成分吗？你认为此题应填which吗？换句话说，填空句是一个非限制性定语从句吗？如果你正是这样认为的，那你就大错特错了。
2. She promisedhe had enough money she would marry him.A. thatB. ifC. that ifD. if that
此题答案应选A还是B？另外，that与if可以连用吗？若可以，是that if还是if that？其中的that可以省略吗？
3.“Each of the students, working hard at his or her lessons,to go to university.”“So do I.”

空白处是谓语还是非谓语？该填hope(s)还是hoping?其中的working hard at his or her lessons在句中起什么作用？
