Question

英语语法问题求教~

the amount spent by industrialised countries had doubled to more than 300 billion......其中，spent的词性和做什么成分，好像有被动的意思，能不能再举几个例子，如何用。

Answer 1

spent 是 spend 的被动形式
这个句子完整的应该是 The amount (which was) spent by industrialised countries had doubled to more than 300 billion.
这里的 (which was) spent by industrialised countries 为定语从句，修饰 the amount的

The girl hurt by me has gone to another city.即 The girl who was hurt by me has gone to another city. 你想你翻译的时候不是说“那个被我伤害的女孩已经去了另一个城市”吗？
所以 很明显可以看出这个定语从句就类似于形容词 修饰名词的~~~

Answer 2

动词，原型是spend，这里是被动的用法，所以变成了 spent
例子：
At least $100,000 spent on that museum has been proved useless.
花费在博物馆上的至少有10万美元被证明是毫无用处的。

Answer 3

spent by industrialised countries作the amount的后置定语，完整形式是the amount (that is) spent by industrialised countries，这些作为整体是本句的主语。

Answer 4

过去分词做后置定语
改成定语从句的话就是 The amount which is spent by industrialised countries had doubled to more than 300 billion.
EG：The lecture given by Professor wu was a great success.
(the lecture which is given by Professor wu was a great success

Answer 5

spent 是spend 的过去式，是动词 做谓语成分，意思是花费，一般句子有 1、somebody spend sometime （some money ）on something 2 、it was spent sometime （some money ）on something by somebody。这是我初中的时候学到的，希望有帮助哈

Answer 6
