talkingaboutthingswecan’tdo.

談論我們不能做到的事是沒有意義的。It’snousedoingsth.做某事沒有用在這個句型中，動詞-ing形式是主語，it是形式主語。類似句型還有Itisnogooddoingsth.(做某事不好/沒用/不行)和It’sawasteoftime/moneydoingsth.做某事是白費時間/金錢等。e.g.

Itisnogoodtalkingtohimbecauseheneverlistens.

他講沒用，因為他從來不聽。

It’sawasteoftimetalkingtoherwhenshe’sinthismood.

在她目前的心情下，找她談是白費時間。less和fewer分別是little和few的比較級。less用于修飾不可數(shù)名詞；fewer用于修飾可數(shù)名詞。4.Thatmeanslesswaste.

這意味著減少浪費。

lessadj.較小的;較少的

n.較少數(shù);較少量拓展e.g.Thedoctoradvisesmetoeat
