7.Firstly，explring space has already made a difference in the fight against wrld hunger.(教材P44)首先，探索太空已经在战胜世界饥饿方面发挥了作用。
【句式解读】　句中“explring space”为动名词作主语。【用法总结】　动名词作主语有如下几种常见情况：1.直接位于句首作主语。2.用it作形式主语，把动名词(真实主语)置于句尾作后置主语。常用于“It is n use ding...”，“It is n gd ding...”，“It is fun ding...”，“It is a waste f time ding...”等句型中。
3.动名词的复合结构作主语。当动名词有自己的逻辑主语时，常可以在前面加上一个名词或代词的所有格作动名词的逻辑主语，构成动名词的复合结构。动名词的复合结构也可以在句中作主语。4.动词不定式和动名词都可以用作主语。在意义上相近。但动名词多用来表示泛指或抽象动作，不定式多用来表示特指或具体动作。①Swimming is a gd sprt in summer.夏天游泳是一项很好的运动。②It is n use/n gd crying ver spilt milk.覆水难收。③It is a waste f time persuading such a persn t jin us.劝说这样的人加入真是浪费时间。④Yur ging there will help a lt.你到那里去将能帮上大忙。

8.It is necessary t find a new hme fr peple in space，as the resurces n Earth will run ut.(教材P45)由于地球上的资源将耗尽，有必要为太空中的人们找到一个新家。
【句式解读】　It is necessary t find...句型，意为“……是有必要的”。it为形式主语，不定式短语t find a new hme fr peple in space作真正的主语。I feel it is ur duty nt t pllute ur envirnment.我感觉我们有责任不污染我们的环境。【用法总结】　it作形式主语常用于下列句型中：(1)It＋be＋形容词＋(fr/f sb) t d sth(2)It is＋n.＋t d...(3)It takes sb sme time t d sth干……花了某人……时间
①It is very kind f yu t lend me the bk.你把书借给我实在太好了。②It is very imprtant fr us t finish wrk n time.对我们来说按时完成工作是很重要的。③It is a great hnur t be invited t speak here.很荣幸被邀请在这儿发表演讲。④It takes me an hur t walk there and back.我步行一个来回用一小时。
