答案
Ⅰ.1.talking　2.recycling　3.napkins 4.to finish　5.staying
Ⅱ.6.turn off　 7.stop polluting 8.Recycling paper　9.shouldn't; napkins 10.when shopping
Ⅲ.11.D　考查非谓语动词。句意:当你离开时,请关灯以节省能源。根据句意可知此处应用动词不定式作目的状语。故选D。
12.A　考查非谓语动词。句意:“过来看看!这个小男孩正在哭。”“请拿给他一架飞机模型让他停止哭泣。”make sb. do sth.意为“使某人做某事”,排除C项;stop doing sth. 意为“停止做某事”,指停止正在进行的事情;stop to do sth. 意为“停下来去做另一件事情”。前句提到了“这个小男孩正在哭”,由此可推知后句应表示“拿一架飞机模型让他停止哭泣”。故选A。
13.A　考查情态动词用法辨析。句意:人们在开车的时候不应该打电话。shouldn't意为“不应该”。故选A。
14.C　考查非谓语动词和介词辨析。句意:“每天练习钢琴花费我半小时的时间。你呢 ”“我通常花20分钟练习弹钢琴。”第一空考查句型“It takes sb. some time to do sth.(做某事花费某人多长时间)”。第二空根据spend可知考查短语“spend+时间+on sth.(在某事上花费多长时间)”。故选C。
15.D　句意:“刷牙的时候,不要让水一直流着。”“对不起。我忘了关上它了。”turn off意为“关闭”;turn on意为“打开”。根据句意可知此处表示忘了关上,故用turn off。turn off为动副型短语,当人称代词作宾语时,应放在动词和副词之间。故选D。
16.C　考查动词时态和语态。句意:彩虹是当阳光穿过空中的小水滴时形成的。主语“rainbows(彩虹)”和动词“produce(形成;产生)”是动宾关系,所以用被动语态。陈述真理和客观事实用一般现在时。故选C。
17.A
Ⅳ.18.pollution　19.stars　20.see　21.good　22.to rest　23.how　24.stop　25.towards　26.up　
27.small　28.still
