高一英语一个疑点
The little boy still needs the _____ 20 dollars to do with some things _____.
A.remaining; remained to be settled
B.remaining; remaining to be settled
C.remained; remained to settle
D.remained; remaining to settle
为什么后面是remaining to be done而不是remained to do 不要找百度!

很高兴为您解答如下：
The little boy still needs the _____ 20 dollars to do with some things _____.
A.remaining; remained to be settled
B.remaining; remaining to be settled
C.remained; remained to settle
D.remained; remaining to settle
第一个空要填的是一个形容词,作定语修饰后面的20 dollars
remained “保持（过去式/过去分词）”,没有形容词性
remaining "剩下的,剩余的",形容词
第二个空：remain to be done “有待于去做”,注意是修饰some things,物体不能主动去处理,只能被动,所以用被动语态to be settled,本句中使用remaining 现在分词短语做定语；
请注意：【remain 是没有被动语态的】

再问： 你是说一个没有被动语态的词在非谓语中表示被动也不能用ed而用ing？？那有其它类似的例子吗
再答： remain 是不及物动词，也是系动词，它没有被动语态，无论是作谓语还是非谓语状态，都没有被动。
Little of the original architecture remains. 原先的建筑物几乎没有残留。
A few pears remain on the trees. 树上尚留有几颗梨子。
There had been 15 apples on the table. Ten apples were eaten with five remaining.
再问： 那类似remain的词还有那些啊？？？
再答： 1 不及物动词或短语无被动语态：
appear, die disappear, end (vi. 结束), fail, rise, fall, happen, last, lie, remain, sit, spread, stand
break out, come true, fall asleep, keep silence, lose heart, take place.
After the fire, very little remained of my house.
2 还有一些及物动词也无被动语态：

fit, have, hold, marry, own, wish, cost, notice, watch agree with, arrive at / in, shake hands with, succeed in, suffer from, happen to, take part in, walk into, belong to

3 系动词无被动语态：
appear, be become, fall, feel, get, grow, keep, look, remain, seem, smell, sound, stay, taste, turn
It sounds good.
4 带同源宾语的及物动词，反身代词，相互代词，不能用于被动语态：
die, death, dream, live, life
She dreamed a bad dream last night.
5 当宾语是不定式时，很少用于被动语态。
(对) She likes to swim.
(错) To swim is liked by her.
