求详细剖析

Answer 1

第一题：ought to表示客观，should表主观，自己认为。 意思是“大厅安装了喇叭好让大家都能听到演讲” 第二题 选B。意思是“这正是我们所期望的一大成功”。考查as…as结构，即“as much of a +可数名词单数+as”

追问

it was __we had hoped
a.more a success than
b.as much of a success as
c.a success more than
d.a success as much as
a选项错在哪里呢？

追答

单拿A选项说。在短语more than里，如果more 后面加的是名词，（如例句的a success）那么than后面必须还是名词，表示“是....而不是”。a选项本身就是一个错误答案。

Answer 2

ought to和must一样，都是一定的意思，不过语气稍弱。
should表推测，用在这里比较合适。毕竟你不能肯定大家能听到。

之前看错题了，选B，我们需要的就是成功

Answer 3

1、ought to have done 指主观上本来应该做而未做
should have done 指客观上本来应该做而未做
2、C
more than we had hoped作定语修饰success，翻译为：这次取得的成功出乎我们的意料。

Answer 4

the possible answer is c
i was a success more than we had hoped.

Answer 5

第一题：D 是应该，而A是必须，由题可知麦克风的位置是固定的，因而每一个人应该都有机会听到演讲，而不是每一个人都必须有机会，这是对这大厅设置的描述，ought to 太主观了。
第二题：b 这正是我们期望的成功
