C 1. Although ______ Spanish, he attended the course.
A. he was knowing
B. he is knowing
C. having a knowledge of D. knows
解析:know是静态动词,不能用于进行时;选knows从句中又缺少主语。knowledge作“知识”讲时是不可数名词,但作“了解”讲时,前面可加“a”,常用于词组have a knowledge of中
B 2. You ______that letter to James. However, you didn’t.
A. ought to write B. ought to have written

A 5. The back garden of our house contains a lawn, ______very pleasant to sit on in summer. A. which is B. which it is C. it is D. where it is

宾关系
C 6. He set up in business ______ his own and was very successful.
A. in B. of C. on D. by
解析:on one’s own 是个常用的介词词组,意为“独自”;of one’s own表示“某人自己的(东西)”
C 7. John’s score on the test is the highest in the class; he ______last night.
A. must study B. should have studied
C. must have studied D. is sure to study

4.小结
这个星期我们学习了虚拟语态,其中WERE-型虚拟式只有出现在单数第三人称主语之后,它才在形式上与陈述式WERE区别开来。还有用情态动词过去形式表示假设意义如:should, would,might,need等。最常见于条件句和含蓄条件句以及某些特定的语境。
