格处引导定语从句，先行词是"a ship"，关系词在从句中作主语，故填which/that。

　　6．rescuers　他问他的一个救援人员："你们怎么知道我在这儿？"空格处应填表示人的名词rescuer，再由句中的"one of"可知此处应填名词rescuer的复数形式。

　　7．discouraged　discourage是及物动词，表示"使沮丧，使气馁，使灰心"，get/be discouraged表示"灰心丧气，气馁"。

　　8．because/as　根据语境可知，"God is at work in our lives ..."解释了"we shouldn't lose heart"的原因，因此填because/as。

　　9．a　句中的signal表示"信号"，是可数名词，smoke signal意为"烟雾信号"，此处表示泛指，故填不定冠词a。

　　10．ourselves　say to oneself是固定短语，表示"自言自语，心里想"。

　　Ⅱ.短文改错

　　Last winter, the smog occurred a lot of time. It brought much inconvenience to our daily life or did great harm to our health. Many traffic accidents had happened just because of the heavy smog weather. In addition, quite a lot of flights had to put off and a great number of people stayed at home to keep them away from the harmful air. Some people suffered of bad coughs, sore throats and other serious diseases cause by the smog. I think whomever lives on the earth should try to play the part in the environmental protection. I support the idea that we can try to drive more and buy environmentally friendly products to improve the air quality.
