答案及解析：A
句意：虽然全球的经济有复苏的迹象，许多发展
(?http:?/??/?www.21cnjy.com?)中国家仍然处于困境。表示“虽然”且置于句首的词有：while,
although,
though。as有“虽然”的意思，但必须用于倒装句。如：child
as
he
is

he

a

B.

C.
soon
D.
immediately
答案及解析：D
空格后面是一个句子，说明是主从
(?http:?/??/?www.21cnjy.com?)句，其需要一个连词，与主句进行连接，四个选项里，只有A是连词，意思是“就在……的时候”，但while通常和持续性动词连用，而enter是种植性动词，所以排除。其他选项:1.upon(介词)“在……之上，在……后立即”。2.soon(副词)“很快，一会”。
副词(adverb，简写为adv)是一种用来修饰动词、形容词、全句的词，说明时间、地点、程度、方式等概念的词。3.immediately(副词)“立即，马上”但是它可以用做连词相当于as
soon
as（一---就）引导时间状语从句，故选D。21

to
be
a
good
doctor.【版权所有：21教育】
A.
that
B.
what
C.
whether
D.
how
答案及解析：B
句意：人们普遍认为，沟通技巧正逐渐成为
(?http:?/??/?www.21cnjy.com?)一名好医生的必备条件。在名词性从句中，that无意义且在从句中不作任何成分；what“什么；……的东西”，在从句中作主语，宾语或表语。whether“是否”，在从句中不作任何成分；how“怎样”，在从句中作方式状语。
“__it
takes
to
be
a
good
doctor”是表语从句，从句中缺少takes的宾语，故用what来引导。故选B。21教育名师原创作品

when当……时候；B.

as
if好像。?while
用作连词时，连接两个并列句子，表示“对比”关系。故选B。

though好像。句意：凯特从来没有感到孤独的时候，即使她是独生子女。故C选项正确。
12.It

________
he
could
find
his
“root”
in
Africa
_________
made
Alex
Haley
decide
to
go
to
Gambia.
A．that;
where
B．where;
that
C．that;
that
D．how;
which
答案及解析：C
根据句子结构及成分可知，本
(?http:?/??/?www.21cnjy.com?)句主干是强调句型：It
is
+被强调部分+that
+其它部分；第一空处引导belief的同位语从句，从句成分齐全，应使用只起连接作用的代词that引导；第二空处则应是强调句中的that。句意：就是Alex
Haley能在非洲找到他的根的想法使他决定去赞比亚。故C选项正确。【来源：21·世纪·教育·网】
13.It
is
so
go
(?http:?/??/?www.21cnjy.com?)od
a
habit
to
instruct
children
to
lay
things
they
belong
when
they
are
young.
A.
to
which
B.
where
C.
in
which
D.
that
答案及解析：B
句意：在孩子们小的时候，教
(?http:?/??/?www.21cnjy.com?)导他们把东西放在它们原来放的地方是一个非常好的习惯。通过分析从句"________
they
belong"的句子成分可知主语是they，谓语是belong，belong是不及物动词，后面不直接跟宾语，另外由"lay
sth．sp．"此结构可知本句考查的是地点状语从句，并非是定语从句（where引导定语从句的先行词必须是表示地点的意义的名词）；A、C和D项均用来引导定语从句，所以答案选B。
14.My
mother
wants
to

__________
my
father

traditional
style.
A.
as
long
as
B.
as
C.
while
D.
now
that
答案及解析：C
句意：我妈妈想用现代的眼光来装饰我们的房间，
(?http:?/??/?www.21cnjy.com?)而我父亲则喜欢传统的风格。此处while（然而）是并列连词，表示前后形成鲜明的对比，故选C。A.
as
long
as只要；
B.
as当---时候，由于；C.
while然而；D.
now
that既然。
15.He

_______he
could
get
there
before
nine
A.
in
order
that
B.
because
C.
so
as
to
D.
in
order
to
答案及解析：A
句意：他出发的很早为了他能够9点之前到那里。
(?http:?/??/?www.21cnjy.com?)
in
order
that
="so"
that+从句，为了……，以便……，引导目的或结果状语从句。题目缺少表示目的“为了”的短语，而B,because引导原因状语。且句中又有could，有些矛盾，可以说：He
got
there
before
nine
because
he
started
early
.；so
as
to="in"
order
to（+动词原形）都是表示“为了”，表“目的”或“结果”，但是，它们不能接从句。故选A。
16.Your

would
b

B.
because
C.
once
D.
unless
答案及解析：D
句意:你的工作会做的更好如果你
(?http:?/??/?www.21cnjy.com?)不是那么地匆忙的话。when当……时候；because因为；once一旦；unless如果不。根据句意故选D。
点评：本题难度适中。连词是近几年高考常考的语法项目，主要考查的是它们的用法及意义，还需正确理解句意及正确分析句子的成分才能做出正确的判断。21·世纪

If
C.

D.

答案及解析：D
句意：虽然警方没有驳回这一想法，但他们也在
(?http:?/??/?www.21cnjy.com?)寻找其他可能性。分析句子前后两句是转折关系，分析四个选项可知，只有while是表示转折关系，故选D项。

Once一旦。根据语境可知，空格处表示条件，“除非，如果不”。故选C项。

一
(?http:?/??/?www.21cnjy.com?)段时间
before…一段时间以后某事才发生；如果before后面使用一般现在时，前面的主语使用将来时；如果before后面使用一般过去时，前面也使用一般过去时。句意：政府已经采取措施来解决电量短缺的问题，但是也许要一段时间以情况才会有所改善。故D正确。

C.
that
D.

答案及解析：B
句意：——杰克昨晚回来得很早
(?http:?/??/?www.21cnjy.com?)吗？——是啊，他到家的时候还不到8点。before在……之前；when当……的时候；that那个；until直到；根据答语中的"yes"可知，要表现Jack昨晚早早就回家了，不能用not…until，因为它是指"直到8点才到家"；如果要使用强调句型It
was…that…，应在强调的部分not
yet
eight
o'clock前加上介词at才行，故用when引导时间状语从句最合适，译为"还未8点就到家了"。故选。www.21-cn-jy.com
