og 13 43 but的用法

stellalights

Laos has a land area about the same as Great Britain but only 4 million in population, where many are members of hill tribes ensconced in the virtually inaccessible mountain valleys of the north.

A. about the same as Great Britain but only 4 million in population, where many
B. of about the same size as Great Britain is, but in Laos there is a population of only 4 million, and many
C. that is about the same size as Great Britain’s land area, but in Laos with a population of only 4 million people, many of them
D. comparable to the size of Great Britain, but only 4 million in population, and many
E. comparable to that of Great Britain but a population of only 4 million people, many of whom

不明白这里的E中but是做连词吗？laos has a land ...but (has) a population...?但是这里也可以解释为 除了（介词）的意思啊，不会有歧义么？？。。。还有平行省略的时候动词也可以省略吗？我怎么只接触到助动词什么的省略额


thanks in advance ~~

绝对没有 but肯定不是做介词 语意根本讲不通 你不能因为介词加名词就强加勉强but的这个意思
你也可以去查字典
but作为介词时候的意思是 but is used to mean except 你替换成except看看讲得通么？

那么but在这里没有作介词表示“除了”这个意思的嫌疑吗？

flonacui

you use but to introduce something which contrasts with what you have just said, or to introduce something which adds to what you have just said.
例句
Place the saucepan over moderate heat until the cider is very hot but not boiling.
He not only wants to be taken seriously as a musician, but as a poet too.

这是柯林斯字典给出的即使和例句 只要是这个意思的but可以接句子可以接短语 只要是对称结构就对~

In grammar, a conjunction (abbreviated CONJ or CNJ) is a part of speech that connects two words, sentences, phrases or clauses together
这是维基百科上的解释 所以是可以connets 句子 词语 短语的

这个but其实就是这么理解，lz知道N has A and B吧，那N has A but B，不是一个意思么，就是and给出AB之间并列平行的含义，but给出了一个对比转折的含义，laos has a land area （comparable to that of Great Britain） but a population （of only 4 million people）——括号内部都是修饰成分，那你就拨开修饰见主干不就得了，亲

but作为介词是除了的意思。。。这里显然不是啊

我来试试回答一下~
but 可以做 连词、副词和介词。这里就是作为介词的情况（介词+N.）
你说的动词省略的情况我不是很明白，是说的that of Great Britain 后面么？因为这里 that of Great Britain 和 a land area 平行，所以不用动词的啊~

顶顶~~

求助求助~~就像我以前做到过一道题，not...but...选项里不选这个，说这里but可以解释为除了，也可以解释为 而是，所以选项里选的是not ... but rather，这样就只能解释为而是
