Question

SAT语法求助

1.The seven-year-old baby was considered precocious to her family because she was already able to grasp tiny items delicately between her thumb and forefinger.
这里her错了，是不是七月大的宝宝要用it?
2.Not very particular in nesting sites, house wrens may nest in birdhouses, mailboxes, building crevices---even in the pockets of hanging laundry.
in错了，为什么？
3.At the reception were the chattering guests, the three-tiered cake, and the lively music that have become characteristic of many wedding celebrations.
这里characteristic为什么不用复数？

Answer 1

对于楼上这些 几近 误导的说法.......无奈了.....

1. 不是her错了, 因为后面已经用she指代了baby 已经指明是女的; 被认为应该用by: be considered precocious by her family. 被动用by 还有什么争议么??
2. particular in 改为particular about, particular有 挑剔的意思, 说家雀对建巢不挑剔, (所以它们把窝建在信箱里楼缝里), 做挑剔讲时 搭配为 particular about
3. 在接待处的是 吵闹的顾客, 三层蛋糕, and生动的音乐, (这些) 已经成为了 许多婚礼庆典的标志. 成为标志的 是 客人 蛋糕 和音乐 三种东西, 应该成为三个特征, 用复数 characteristics.

Answer 2

1、是的，一般来说，baby的代词是用it的
2、in→about，与particular搭配的介词是about，不是in！
3、这里的characteristic是形容词，be characteristic of sth，（become≈be）

Answer 3

我的意见除了第三个和楼上的一样，其它都不一样。第一题，不是her错了，是to错了，改成by。第二题，词语搭配错误，in改成about。
楼上的太对了太对了，本人才疏学浅，sorry了
