Answer 1

【答案】

【1】at the top of

【2】make a difference

【3】to cut off

【4】is harmful to

【5】cut up

【解析】

【1】根據(jù)the food chain以及humans，可判斷at the top of，即“人類(lèi)是食物鏈的頂端”。

【2】根據(jù)if you put your hear以及前半句，可知make a difference“產(chǎn)生影響”符合語(yǔ)境。

【3】此處為ask sb to do sth的被動(dòng)式，即sb be asked to do sth；根據(jù)unnecessary判斷cut off“減少”符合語(yǔ)境。

【4】由常識(shí)可知，垃圾食品對(duì)人類(lèi)的健康有害，因此be harmful to符合語(yǔ)境。

【5】根據(jù)空后的賓語(yǔ)判斷cut up“切開(kāi)；切碎”符合語(yǔ)境；由gave可知句子為過(guò)去時(shí)，cut的過(guò)去式仍為cut。
