Question

麻烦各位讲解一道英语选择题，谢谢

___ the blanket kicked away by the girl,her mother tucked it tightly under her.
A.on the time B.on seeing C.at seeing D.at time

为什么选这个答案，这句是什么意思？

Answer 1

这句话的意思是说她妈妈偶尔会在毯子被她踢开的时候帮她把毯子掖在身下。
我觉得应该选D，因为D选项中的at time意思是有时候，偶尔，而且主句中tucked用的是一般过去时，表示是经常性的行为，与句意相符。

Answer 2

prefer
to
do
sth.为固定结构，译为“偏爱、宁愿干什么”。至于主语和give之间显然是动宾关系，用被动结构。可翻译为:约翰逊先生喜欢挑重担(被赋予重任)。
这样的解释你满意吗?

Answer 3

C
妈妈一看到毛毯被女孩踢掉,就帮她塞紧.
on seeing=as soon as her mother saw 这里seeing是saw的动名词形式
类似用法如:
As soon as he arrived, he set about working.他一到达就着手工作.
= On arrival, he set about working. 这里arrival是arrive 的名词形式.

Answer 4

在与家长谈话时,校长看起来对这个淘气的男孩很生气.
D
while
talking
with
his
parent,实际上是个省略句.相当于:
while
the
school
master
was
talking
with
his
parent
当从句与主句的逻辑主语一致,并且有be动词时,可以省略相同的主语和be.
如:I
met
an
old
friend
when
walking
in
the
street
yesterday.
=
I
met
an
old
friend
when
I
was
walking
in
the
street
yesterday.

Answer 5

选B吧。on seeing就是when she saw，类似的还有on hearing ,on arriving之类的。
