spend
1.不可说I shall not spend much of your time，该把spend改作take up。
2.下面每组里的三句意思相同，似乎用for最不普通：
- He has spent ten yuan on sweets.
He has spent ten yuan in sweets.
He has spent ten yuan for sweets. - She spends most of her money on books.
She spends most of her money in books.
She spends most of her money for books.
3.He spends his evenings (in) reading fiction和He spent most of his life (in) travelling以及Instead of working hard at her lessons, Mary used to spend her time (in) building castles in the air等句子里的in可有可无。注意不可说He spends his evenings to read fiction等。
4.比较下面两句：
- He spent half a year (in) writing a short play. （他花了半年时间写一个短剧。）
- He spent half a year on writing a short play. （他把半年工夫花在写一个短剧上。）
第二句几乎等于It took him half a year to write a short play。
