1.答案:be committed/devoted to researching energy-efficient/energy-savingproducts//devote themselves to researching energy-efficient/energy-saving products
詳解:
考查固定搭配:“致力于”的固定搭配是be committed/devoted to或commit/devote oneself to.其中to是介詞，后面要跟名詞性成分，故用名詞或動名詞。
考查固定表達:“節(jié)能產(chǎn)品”的表達為energy-efficient products或energy-saving products。
2.答案:everyone(should)turn/hand in homework/assignments on time
詳解:
考查虛擬語氣:ask,advise,insist,order,suggest,command,demand,propose,require,desire等表示主管判斷，推測，建議，命令和要求的動詞引導的賓語從句中要用虛擬語氣，從句中的謂語應為“(should)+動詞原形”。
