A. it B. one C. this D. that
答案
1. A【解析】句意：我们都认为有必要停止学校欺凌。A. it它，也可以用作非人称代词，用作形式主语或形式宾语；B. her她；C. that那个；D. this这个。本句用it作形式宾语，to stop school bullying是真正的宾语。故答案为A。
2. C【解析】考查物主代词用法。句意：欢迎你们所有的人来广元，愿你们在这里玩得愉快。A. you 你，你们，是人称代词；B. your 你的，是物主代词；C. yourselves 你们自己，是反身代词。短语enjoy oneself，意为玩得愉快，根据前面的you all可知是复数反身代词，用yourselves，故选C。
3. D【解析】句意＂我弟弟丢了他的手表，现在他正在找它＂。A.one作代词时，指同类不同物；B.这个，近指；C.钠，那个远指；D.it代指上文中出现的同一个事物。根据句意可知，表示＂寻找他丢的手表＂，表示同一个事物，故选D。
4. A【解析】句意：——打扰了，我想要一些书，但在这里找不到书店。——我知道在我回家的路上有一个。请跟我来。考查代词辨析题。A. one一个；B. this这个；C. it它；D. that那个。this/that表近指或远指，it代替上文提到的（同一）事物；one指的是与前面提到的为同一类事物，相当于＂a+名词＂。本句所指与上一句属于同类而不同物，需用one。
5. B 【解析】句意：——Ed，你喜欢董卿主持的《读者》吗？——是的，我每天观看它。A. one一个，同类事物中的一个；B. it它，上文提到单数名词，下文再次提到用代词it代替，指同名同物；C. them他们。这里是说上文提到的《读者》,这里用it。根据题意，故选B。
6. B【解析】句意：看！这些男孩们在自己制作模型船。himself他自己；themselves他们自己；ourselves我们自己；yourselves你们自己。by oneself意为＂独自，单独地＂，是固定短语。该句话的主语是The boys，第三人称，因此这里指＂他们自己＂，故选B。
7. A【解析】句意：不管我做什么，我都是为你做的。别怀疑，孩子。Whatever无论什么；B. Wherever无论在哪里；C. Whenever无论何时；D. Whoever无论谁。分析句子___________ I do, I do it for you. 的结构可知，本题缺少的是宾语，也就是do的宾语，能充当宾语的是选项A/D，故排除B/C；Whoever无论谁，指人，做do的宾语不合适，排除。whatever 是连词，引导让步状语从句。从句意上说是在从句中做do的宾语。语境是：不管我做什么，我都是为你做的。故选A。
8. A【解析】句意：同学们，请自学我们明天要学的文章。teach oneself 自学，因为Class在这里表示复数，所以反身代词用yourselves。故选A。
9. D【解析】句意：——先生，我能帮您挑选牛仔裤吗？——是的，我想试穿那些蓝色的牛仔裤。根据those blue可知用复数，代词ones代替jeans，句意：是的，我想试穿那些蓝色的牛仔裤。故选D。
10. C【解析】根据句意"我们早上不吃早餐去上学是不健康的"和语法可知，后面的不定式to go to school without eating breakfast in the morning是真正的主语，前面用it作形式主语，that和this都不能作形式主语。所以选C。
