unless
I am invited.A.because
B.and
C.but
D.unless
答案
D
解析
根据句意“我不会去,除非我被邀请”,“unless”表示“除非”,符合语境。because表原因,and表并列,but表转折,均不符合。
(
A.boil; turns
B.will visit; will be

A
) 2.If you ______ the water, it ______ into gases.A.boil; turns
B.will visit; will be
C.will boil; turn
D.will boil; will turn
答案
A
解析
本题考查条件状语从句的时态用法。在条件状语从句中,若主句为一般将来时,从句用一般现在时表将来。题干前半句“If you ______ the water”为从句,应用一般现在时,主语是you,动词用boil;后半句“it ______ into gases”为主句,用一般将来时,但此处turn的第三人称单数形式为turns在此(由于主句描述的是客观事实或普遍真理时,也可用一般现在时表将来)符合主句(客观事实用一般现在时)表达逻辑。A选项符合题意。
(
A.visit; will be
B.will visit; will be
C.will visit; am
D.visit; am
C
) 3.I ______ you if I ______ free tomorrow.A.visit; will be
B.will visit; will be
C.will visit; am
D.visit; am
答案
C
解析
本题考查条件状语从句的时态用法。在条件状语从句中,如果主句是一般将来时,从句用一般现在时表示将来。主句“I ______ you”应使用一般将来时“will visit”,从句“if I ______ free tomorrow”应使用一般现在时“am”。因此,正确答案是选项C。
( ) 4.
A.If
B.Because
C.Unless
D.Until
C
you have lots of money, you can't buy that house.A.If
B.Because
C.Unless
D.Until
答案
C
解析
本题考查条件状语从句的连接词。根据句意“除非你有很多钱,否则你无法购买那栋房子”,需要选择表示“除非”的连接词。选项中只有unless符合语境。if表示“如果”,because表示“因为”,until表示“直到”,均不符合句意。
(
A.and
B.though
C.but
D.if
D
) 5.You will fail the exam ______ you don't study hard.A.and
B.though
C.but
D.if
答案
D
解析
前半句"You will fail the exam"(你会考试不及格)是结果,后半句"you don't study hard"(你不努力学习)是条件。根据八年级上册第三课时Grammar所学,此处需用表示条件的连词。A.and表并列;B.though表让步;C.but表转折;D.if表条件。故用if。
(
A.unless
B.when
C.if
D.because
A
) 6.You won't learn English well ______ you work hard.A.unless
B.when
C.if
D.because
答案
A
解析
句意:除非你努力学习,否则你不会学好英语。"unless"表示"除非",引导条件状语从句,符合句意;"when"当……时,"if"如果,"because"因为,均不符合逻辑。
( ) 7.
A.Unless
B.If
C.Though
D.Until
B
you don't go to bed earlier, you will feel tired tomorrow.A.Unless
B.If
C.Though
D.Until
答案
B
解析
本题考查连词的用法。题干意思是“____你不早点睡觉,你明天会感到疲倦”,根据句意判断,这是一个条件状语从句,表达“如果你不早点睡,就会累”。选项A“Unless”表示“除非”,不符合句意;选项B“If”表示“如果”,符合条件关系;选项C“Though”表示“虽然”,引导让步状语从句,不符合句意;选项D“Until”表示“直到”,引导时间状语从句,也不符合句意。因此选择B。
(
A.unless
B.because
C.if
D.though
A
) 8.I won't come to see you ______ I am asked to.A.unless
B.because
C.if
D.though
答案
A
解析
本题可根据各选项连词的含义,结合句子逻辑关系来进行选择。句子表达的是“我不会来见你,_____ 我被邀请”,需要找到一个合适的连词来连接前后逻辑。A选项“unless”意为“除非”,若填入句中,句子逻辑为“除非我被邀请,否则我不会来见你”,符合常理;B选项“because”表示“因为”,代入句中逻辑不通;C选项“if”表示“如果”,代入句中不符合语境;D选项“though”表示“虽然”,也不符合句子逻辑。

if so unless but when since until
Can you imagine going deep into a whole new world—inside a volcano (火山)? 1.
When
a volcano erupts, smoke 2. bursts
(burst) into the sky. Rocks and ash shoot up into the air, and lava rolls down the mountain. Who in their right mind would want to come close to something like that? No one, of course. However, 3. unless
it were dangerous, how exciting it 4. would be
(be) to explore inside a volcano. 5. If
you are interested, Iceland seems to be the only place on Earth where you can go down inside a volcano. Thrihnukagigur volcano's last eruption was 4,000 years ago and it 6. has remained
(remain) dormant ever 7. since
. A dormant volcano is "sleeping" 8. but
is expected to erupt again sometime. Dormant volcanoes still contain liquid rock called magma. But it won't come to surface 9. until
it is hot enough and under enough pressure. Its magma chamber is empty, 10. so
visitors can now explore it.答案
1. When 2. bursts 3. unless 4. would be 5. If
6. has remained 7. since 8 but 9. until 10. so
解析
1. 考查连接词。句意“当火山爆发时,烟会冲向天空”,用when引导时间状语从句,首字母大写,填When。
2. 考查时态。when引导的时间状语从句“主将从现”,从句用一般现在时(erupts),主句用一般将来时,填will burst。
3. 考查虚拟语气。句意“如果它是危险的”,if引导虚拟条件句,从句用were,填if。
4. 考查虚拟语气。if虚拟条件句(与现在事实相反),主句用would+动词原形,填would be。
5. 考查连接词。句意“如果你感兴趣”,用if引导条件状语从句,首字母大写,填If。
6. 考查时态。“ever since”提示用现在完成时,主语it,填has remained。
7. 考查固定搭配。“ever since”意为“自从那时起”,填since。
8. 考查连接词。前后句“沉睡”与“预计再次爆发”是转折关系,用but,填but。
9. 考查连接词。句意“除非足够热且压力足够大,否则不会到达表面”,unless表“除非”,填unless。
10. 考查固定搭配。指代前文“岩浆室是空的”这一情况,“if so”意为“如果这样的话”,填if so。
