【4】Can the power pack provide energy for the space suit?
【5】This street is becoming more and more crowded.
【解析】
【1】由句意可知本题时态用一般现在时。“火星上的空气”the air on Mars;“稀薄”英文表达是thin,这里应用其比较级的形式thinner,同时用much修饰其比较级表示“稀薄很多”;“比”,than,用于比较级;“地球上的空气”that on the Earth,that指the air;故答案为:The air on Mars is much thinner than that on the Earth.
【2】由句意可知这是一个主从复合句。“我不知道”I don't know是主句,后接宾语从句“他为什么不上大学”,从句是“疑问词+陈述语序”,由句意可知从句应该用一般过去时。“为什么”why,主语是he,“上大学”go to university,所以否定结构需加助动词didn't。故答案为:I don't know why he didn't go to university.
【3】由句意可知这是一个主从复合句。“我认为”I think是主句,后接that引导的宾语从句;主语是“我们”we;“应该”should,后接动词原形;tell him the truth of the event告诉他事情的真相;故答案为:I think that we should tell him the truth of the event.
【4】由句意可知本题是由情态动词can引导的一般疑问句。“能”can,后接动词原形;“能量包”the power pack,“提供”provide,“能量”energy,“为太空服”for the space suit;故答案为:Can the power pack provide energy for the space suit?
【5】由句中“正变得”可知时态应该用现在进行时,其结构为be+动词现在分词。“变得越来越拥挤”become more and more crowded,主语是“这条街”this street,为第三人称单数形式,所以系动词be用is,become的现在分词是becoming,故答案为:This street is becoming more and more crowded.
