The company announced that its profits declined much less in the second quarter than analysts had expected it to and its business will improve in the second half of the year.
had expected it to and its business will improve
had expected and that its business would improve
expected it would and that it will improve its business
expected them to and its business would improve
expected and that it will have improved its business
B:“business will improve” – correctly imply that revenue will improve.
D:It’s not clear whether “its business would improve” is parallel to “analysts expected them to” or “its profits declined…” – both are clauses, so either would be structurally parallel, and that’s confusing.
还原成its profits declined much less in the second quarter than its profits declined as analysts had expected
D选项=its profits declined much less in the second quarter than analysts had expected its profits to decline,
C的 第一个it是致命错。
something declined less than analyst expected 是个错误的平行
something declined less than analyst (had) expected ((that) they would declined) <-可以省略
c用了现在时,和主句announced跨时态,而且没有明显的客观事实标志
另外c错在it指代,前面的profits是复数
没有硬性要求,这里第二个that是和前面的that形成并列
有这个规则。。。前几天看题时有人这么评论了登录 或 注册 后可以参加讨论
he only one of those pronouns that's incorrect is the "it" in choice (c).
in that choice, the context of the pronoun clearly refers to the company's profits; however, "profits" is plural, while "it" is singular.
