Olympics.
A.
until
B.
because
C.
though
D.
when
[答案]
B。[解析]
本题考查连词的用法。until表示“直到……才”常用来引导时间状语从句；because"因为”用来引导原因状语从句，而though"尽管”用来引导让步状语从句。根据主从句的前后关系判断，应该选用表示原因的B项。
【考例】Ricky
caught
a
"bad
cold
yesterday,
________
he
had
to
stay
at
home.
A.
because
B.
but
C.
or
D.
so
[答案]
D。
because
因为，引导句子；because
of因为引导短语But
但是，（表示转折＝however，＝whereas），不能够和though/although连用对不起，除了（＝except）?Or
和（
and的否定形式），或者，否则（通常是将来时态，表示结果）So
所以，表示结果，不能够和because连用；如此引导形容词/副词。句意为：
Ricky昨天得了重感冒，所以他不得不呆在家里。
表让步的从属连词：
although
虽然，尽管
though
although/though的用法：
1.
在一般情况下二者可以互换使用，都可与yet,
still连用，但不能与but连用。
e.
g.
Although
he
is
poor,
he’s
still
happy.
虽然他很穷，他仍然很快乐。
I
will
try
it,
though
I
may
fail.
即使我可能失败,
我也要试一下。
【注意】：
①
although引导的让步状语从句位于主句之前的情况较多，though引导的让步状语从句可位于主句之前或主句之后。
②
though可用于句尾:
We
all
tried
our
best.
We
lost
the
game,
though.
我们都已尽了最大的力量.
不过我们还是输了.
