  make sure表示“弄确实;核实;查证”。make sure常用于祈使句,后面常接that宾语从句或of介词短语。Make sure + that从句意为“弄明白;确信”。Make sure + of + 代词/名词,意思也是“弄明白;确信”。例如:

  — Make sure of his coming before you set off.

  — I make sure (that) he would come.

  — 出发之前要确定他是否来。

  另外,be sure + 不定式大多数情况下也用于祈使句,表示“务必;一定要;不要忘记”。

  (2) to keep it straight 是动词不定式,在句中作状语,表示捆树的目的。keep it straight 为“动+ 宾 + 宾补”结构,如:

  7. But more “Great Green Walls” are still needed, and not only in China.

  但是,更多的绿色长城仍旧需要,这不仅在中国。

  not only 能常和but also连用,意思是“不但……而且……”,可以连接两个主语、谓语、宾语等,当连接两个主语时,谓语动词应和第二个主语在人称和数上保持一致,also往往可以省略。例如:

  She is good at not only dancing but (also) singing. She is both a dancer and a singer.

  她不但善长跳舞,而且善长唱歌。(连接两个宾语)她是个舞蹈家和歌唱家。
