if people do not have a dream, then their lives will lack of impetus.

希望幫到你 =)

引用:

用people 好似怪怪的....
同埋 will lack of impetus..用lack +of /....唔係暗示左ｌａｃｋ　係ｎｏｕｎ　咩．．．但前面　跟　ｗｉｌｌ　．．．

should it be
Without a dream, you have no impetus in your  ...

Lack of impetus
____ of _____

of起中間既時間,, [of前]同[of後]都係要用[NOUN]

other example::
充滿信心 - full of [confidence]
full of [confident] 就係錯架喇..

如有錯,, 請指教
