Q1.Allofthem.Q2.Allofthem.Step2.Explanation.a.
butandhoweverbut作为并列连词,在意义上起转折作用。
but前后的两个句子或短语在意义上形成鲜明对照。
but用来连接两个分句或两个较长的短语时,but前面一般要加逗号。
例如:
(1)Heisoldbutstrong.他年纪虽大却很强壮。
(2)Learningtheguitarisn'
tdifficult,butyouwillhavetopractise.
学弹吉他并不难,但是你得练习。
(3)Hetried,butcouldnotdoit.他试过,但是干不了。
however意为“可是,然而,尽管”,较but的意味弱,通常用作连接性状语。
其位置可以在句首,句末或插入句中。
当其被用来对照两个分句时,中间需要有一个逗号;
当它被用作句子的插入语时,则前后应各有一个逗号。
(4)However,weneednotdothatnow.可是,我们现在不需要做那个。
(5)Hesaiditwasso;
hewasmistaken,however.他说是那样的,然而他却弄错了。
(6)Hisfriends,however,hadotherideas.然而他的朋友们却另有见解。
注:
however也可用作连接副词,意为“不论怎样”,用来引导让步状语从句。
Howeverwemaydoit,itwillbeadifficultjob.无论雪下得多大,我们都必须回去。
b.
althoughandwhile
while表示两个事实之间的转折对比,although可以用but改写成另一种句子while用作连词时,连接两个并列句子,表示“对比”关系。
Hewentoutforawalk,whileIstayedathome. (他出去散步了,而我却呆在家里。
) Ilikesingingwhileshelikesdancing. (我喜欢唱歌,而她喜欢跳舞。
) youlikesports,whileIprefermusic.(你喜欢体育,而我更喜欢音乐。
)although引导的从句放在主句前后均可,有时还可放在句中。
Althoughmanydifficultiesarestillahead,wearedeterminedtomakegreaterachievements.尽管在前面的道路上还有许多困难,但是,我们决心要取得更大的成就。
HeoftenhelpsmewithmyEnglishalthoughheisquitebusy.尽管他相当忙,但是还常常帮我学英语。
although引导的从句不能与but,however连用,但可与yet,still连用。
不能说:
Althoughhewasold,butheworkedhard.应把but去掉。
当然,保留but而去Although也可。
c.
conclusion
,but与however,相同点:
都表示转折,都可以连接两个句子不同点:
①but还可连接两个并列的成分,however不能;
②however可置于句首,句中,句末,而且在句中时前后用分号或逗号隔开的情形较多。
but往往置于句首,无需用标点符号与句子隔开。
2,although与while相同点:
都是连词,都可引导让步状语从句;
不同点:
①although意为“虽然,尽管”,相当于though,所引导的句子通常置于句首。
含although从句的复合句可以转化为由but引导的并列句,但although与but不能同时出现;
②while意为“然而,但是”,可用作并列连词,表示前后的对比,一般不与but转换,所引导的句子不能置于句首。
