第一部分 作业
第一节 名词和代词的数和格、形容词和副词的级
1. Today, ______________major new products without conducting elaborate market research.
A corporations hardly introduce ever B hardly corporations introduce ever
C corporations hardly ever introduce D hardly corporations ever introduce
* 答案为C。hardly提前，句子要求倒装，故排除B、D；hardly 修饰ever，不应将其分开，故答案为C。
2. Of the two houses the family prefers ____________.
A the most isolated one B the one isolated more
C the more isolated one D the isolated one more
* 答案为C。表示两者当中之最，应在比较级前加定冠词，而形容词的比较级应在之前加more, 即the +比较级 + of + the two….
3. “How often did you give him money?” “__________than I can remember.”
A The more time B More time C More times D The more time
* 答案为C。how often表示频率，故后面的time应该是表示次数，此时是可数名词，用more来修饰应加s.
4. ___________errors made by him was surprising.
A The number of B A number of C The amount of D A large quantity of
* 答案为A。errors是可数名词复数，故排除C；本句谓语was为单数，根据主谓一致原则，主语也应为单数，BD都表示大量的（错误），故答案为A，the number of errors指错误的数量。
5.The president of the college, together with the deans, _______a conference now for the purpose of laying down certain regulations.
A is planning B are planning C have been planning D has been planning
* 答案为A。本句主语为the president of the college, 根据主谓一致，谓语也应为单数，而根据时间状语now，本句用一般进行时为宜，故答案为A; 注意together with意为和…一起，但并不影响主谓关系。
6. The kind of books an author writes __________ the kind of man who he is.
A depend on B depends on C depended on D depending on
* 答案为B。本句的关键是找到主语的中心词，然后根据主谓一致关系，决定谓语的形式，从前后来看，本句是说“一个作者所写出的作品种类取决于他是一个什么样的人”，句子的主语中心词是the kind，故答案为B。
7.You can park on ________side of the street.
A either B any C all D both
* 答案为A。指街道两边的任意一边，表示两都当中任何一个，用either. Both表示两者都。
8. The singer and actor ___________to perform the opening ceremony.
A is to be invited B are to be invited C is to invite D are to invite
* 答案为A。本句主语是and连接的两个并列名词，只有一个定冠词，表示的是同一概念，是指一个人既是歌手，又是演员，故谓语应用单数，另外与invite之间的关系应是被动，故答案为A。
9. __________comrade has sacrificed his life for the revolution.
A Many B More than C Many a D So many
