Answer 1

题目：Since
the
restoration
work
started,
the
university____to
preserve
as
many
old
trees
as
possible
and
limit
the
height
of
new
buildings.

A
is
careful
B
had
been
careful

C
has
been
careful
D
was
caful

Explaination:首先拿到题目先大概掌握句子的意思，since的用法主要有两点：一是表示“自从……以来”，二是表示“既然”之意。在这里很明显since表示的是第一种意思，既要用完成时，所以可以排除A和D。接下来从B和C当中选，你看and后面的那个单词limit，没有用过去式所以前面横线上不用表示过去式。两者并列答案选C。

这句话也可以这样说：The
university____to
preserve
as
many
old
trees
as
possible
and
limit
the
height
of
new
buildings
since
the
restoration
work
started.这样的话直接套公式，我举个例子：I
haven't
seen
him
for
a
long
time
since
he
left
Shanghai.
