--- ,thank you.
a.i will b.i hope so c.that's right d.my pleasure 考點3 will people use money in 100years? 一百年后人們還會用錢嗎？
辨析：in,after與later
in和after都可以表示"在...之后"，但用法有所不同。
in是指以現在時間為起點的"在一段時間以后"，也可以表示"在將來多少時間之內"，句中的謂語動詞要用一般將來時態。
he will be back in two days.他將在兩天后回來。
after常常指以過去時間為起點的"在一段時間之后"，所以它常與過去時態連用。當after指某個特定的未來時刻或日期之后或指以將來某一時間為起點的若干時間之后時，它可以與將來時態連用。
he started on sunday and arrived in beijing after three days.他星期天動身，3天后到達北京。
i'll be free after friday.我星期五之后有空。
he will be back after three o'clock.他3點之后回來。
later 是副詞，表示"一段時間之后"，構成"一段時間+later"短語，用于過去時；如果單獨使用，可與將來時或過去時連用。
nine months later they were discovered.九個月之后，他們被發現了。

1.辨析：fewer與less
fewer與less分別為few和little的比較級，都意為"更少的"。fewer與可數名詞復數形式連用，其反義詞為many的比較級more。
less與不可數名詞連用，其反義詞為much的比較級more。
they buy fewer cigarettes and less beer now.現在他們買的香煙和啤酒少些了。
拓展：less也可作副詞，意為"較少地，更少地"，常用來修飾形容詞、副詞或動詞。其反義詞為more，用法與less相同。
eat less,drink less and sleep more.少吃，少喝，多睡覺。
