81,In an effort to reduce their inventories, Italian vintners have cut prices;their wines have been priced to sell, and they are. (C) are priced to sell, and they do (D) are being priced to sell, and have 1,og 的说明是verb form,动词形式。按照其解释,其实时态对于这题几乎没有影响,因为后面and they +助动词(实意动词省略),助动词只能是do。因为前面有have been priced to sell。关键是助动词后面必须加的是原形sell。 所有选项里,只有c后面有do 可加sell,其他要么they are selling,要么have sold。也就是说这题唯一能用于排出其他选项的绝对考点就是动词形式。 不知道这么理解对不对? 2,另,之前我有个帖子提问关于and连接两个并列分句,前面逗号是否仅当两个分句主语相同时才能省略,且此时第2个句子的主语也蒙前省。 这题og对D的解释:。。。;omitting the subject they means that the comma should be omitted as well 是否可以理解成如果前后两个and连接的并列分句,主语相同时,后一个主语可以省,如果这样,那么and前逗号也必须省。即s+v1+o and v2+o,或者s+v1+o ,and s+v2+o 3,关于语法现象。 这题分号后那个分句,虽然用and连接,但仅表一个意思,and分句只是表强调? |
