1.that fall to the ground,take root and and produce new seeds.and 连接的并列谓语.
2.词义辨析.performance 表现.achievement 成就,words 话,material 材料.
3.此处用过去时,因为前面有表示过去的时间,after hours...had done 表示过去的过去.
4.只要 so long as/ as long as.once 一旦 the moment= as soon as 一.就.
5.be to 用在条件句,表示如果想要.
6.此处考察的是替代.此处 that = clothing that = the + 可数名词单数/不可数名词.the ones= the + 可数名词复数 one = a + 可数名词单 what 用于名词性从句,但over 之后不是句子.
7.since/because 因为.when 当什么时候.此处说的是一个客观真理,而不是一件事.
9.to do 左后置定语,为on which we are to base 的省略结构,省略we are.
9.省略结构,there is nothing wrong with it,is there?
再问： 第1题是句子什么意思，take root是什么意思? 第6题 看的有点 云里雾里··· 恩，其他都懂了···
再答： take root 生根 6. 此处考察的是替代。此处 that = clothing 。that = the + 可数名词单数/不可数名词。the ones= the + 可数名词复数 one = a + 可数名词单 what 用于名词性从句，但over 之后不是句子。 如：The weather in Beijing is colder than that(大替the weather) of shanghai. There are many books in the bookstore, but i only like the ones (代替the books) with hard covers. his coat is so handsome that i also want to buy one.(代替a coat) 这些that, the ones, one 都是指和倩文提到的同一类事物但不是同一个
