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】根据the food chain以及humans，可判断at the top of，即“人类是食物链的顶端”。

【2】根据if you put your hear以及前半句，可知make a difference“产生影响”符合语境。

【3】此处为ask sb to do sth的被动式，即sb be asked to do sth；根据unnecessary判断cut off“减少”符合语境。

【4】由常识可知，垃圾食品对人类的健康有害，因此be harmful to符合语境。

【5】根据空后的宾语判断cut up“切开；切碎”符合语境；由gave可知句子为过去时，cut的过去式仍为cut。
