英语教师王太来回答吧：
1.选C；pressure 不可数; the whole society 特指我们这个社会.
2.选B； 例句：My house faces south. 这里的facing的逻辑主语是every great building, 如果改成句子就是：Every great building faces south.
3.选B; 这是一个强调句,去掉强调句型 it was...that, 句子恢复原形：Playingcomputer games costs the boy a lot of time...
4. 选B; 句型：expect somebody to do something, 在这个句型中,也可以说expect there to be (期望那儿有...）
5.选C；这是一个独立主格,意思相当于B； 如果选用B,就需要用一个连词because 放在句首,或用so,放在第二句话开始,因为在英语中,两个句子之间是不能打逗号的,如果什么都不加,就写成两个单独的句子,每句话都要用句号, 或者用独立主格,既：把谓语动词用分词的形式表示.
6.选C；这里的where 引导一个定语从句,相当于：In societies social roles are determined.
7. 选C,过去分词短语作状语修饰主语Harvard, 可以改成句子：Harvard was founded in 1636.我刚刚讲过,在英语中每一个含有主语,谓语的句子都要打句号,不打句号,就要通过其他方法解决.
8.选C;名叫mac和dick的两兄弟收养的不是一个而是八个孤儿,（就这样）,他们在这个城市创办了第一家孤儿院.这里的动词要和离它最近的名词一致,在语法上叫做“就
近原则”.
9. 选A, 依旧是一个定语从句,where 相当于：in this situation
10. 选D,还是定语从句,where 相当于：in the chemistry lab; 每当闲暇时,这位新近退休的教授总是会发现自己被吸引到正在进行该实验的化学实验室.
11.选B. little 放在句首,句子需要倒装,因此A 和C错了；hope之后的句子不能用虚拟would, 而应该用将来时will,因此D错了；wish 后面如果接句子,必须虚拟,因此选B.
12.选D；因为是一个完整的句子作表语,前面必须加that 引导,没有任何意思.
13.选D； 如果表达“什么什么上面写着”就要用say, 也可以用read,如：The note says (reads): “Come to my place right away." 条子上写着：马上到我这儿来.
下次再提问时,可不能这么累人啊!
