1.Although punctual himself,the professor was quite used ----------late for his lecture.
A to have students B for students' being C for students to be D to students' being 求翻译和解释
2.It is vital that enough money be collected to fund the project.
为什么用 be collected?
1.D be used to,习惯于某事。尽管他自己很准时，这个教授却很习惯于学生在他的课上迟到。A中的have做使役动词时应用have sb do sth.2. 筹集足够的钱为这个项目投资很重要.money作主语，钱被筹集。如果用collect 的主动形式应该是It is vital to collect enough money.
