1.The girl was often heard __________ happily in her room.
A. sing B. to sing C. singing
答：B
析：本题考hear sb. do sth. 改成被动语态时的"还to" 考点.
评：本题设计有误.我知道“最佳”答案一定是B,因为初中题不会这么复杂.
其实我心目中这一题的最佳选择是C.如果你不嫌烦,追问的话,我回答.
2.I`ve been collecting old coins __________ten years ago.
A. for B.about C.since
答：C
析：现在完成进行时,延续性用法.for+一段时间,since +过去时间点.如果没有这个ago则选A.
有了这个ago则选C,但说实话,这不是一个好句子.因为ten years ago不是一个很明确的过去时间点!
1：A
2：C
The girl was often heard sing__ happily in her room.
.I`ve been collecting old coins since____ten years ago
A;
A（对于一段时间，用for）
C C
c,c
1. C
2. C
1.c 考察hear +动词原形
表示全过程
+动词ing形式
表示某个状态 只是部分过程
2.c 考查完成时的用法
C;
A
1, A 2. C
1，C 听到某人做某事，应该用ing形式表示动作的同时性
2，C since是现在完成时的标志
第一个选B hear sb do sth 或者是have sb do sth等词组被动的时候动词不定式的符号to要还原的。
第二个选C 表示自从十年前就在收集了，For ten years 就对了
1B 2C
C. singing
C.since
BC
1 b 2 a
B C
cc
1选C 听到正在唱歌
2选C 有ago不用for，前面是完成时后面常与since连用
