6. Firstly, explring space has already made a difference in the fight against wrld hunger. 首先, 探索太空已经在与世界饥饿的斗争中发挥了作用。
【句式解构】(1)本句中划线部分explring space是动名词短语在句中作主语。动名词作主语时, 它已经将动作名词化了, 已把某个动作视为某种活动或是某件事情了, 动作意义很弱, 比较抽象。*Seeing is believing. 眼见为实。
*Reading simplified English nvels is an easy and enjyable way f enlarging ur vcabulary. 阅读简写的英文小说是扩大我们词汇量的一种轻松愉快的方法。*Cheating in an exam ruins ne’s character . 考试作弊毁坏人的品格。
(2)动名词作主语时, 也常用“It is. . . ”和“There is. . . ”两种句型。其中“It is. . . ”的句型常用于说明“某种活动或是某件事情是如何的”, 强调事物的性质、特征等。常用于It is后面的词有: n gd, n use, useless, a waste, wrthwhile, dangerus等等。而句型“There is. . . ”往往用于说明“不允许、禁止某种活动或是某件事情发生或存在”, 类似一种建议或命令。
*It is n use waiting fr him any lnger . 再等他也没有用。 *It is wrthwhile cnsulting yur tutr abut it again . 很值得再向你的指导老师咨询一下这个问题。 *There is n jking abut such matters . 这种事开不得玩笑。
*There is n denying the fact that China has made a rapid prgress in every aspect since it was funded . 毋庸置疑, 中国自它成立以来已在各个方面都取得了飞速的发展。 *There is n littering abut. 不许乱扔杂物。
【名师点津】(1)当不定式(短语)、动名词(短语)或从句在某个句子中作主语时, 为保持句子结构前后平衡, 避免头重脚轻, 因此常用it作形式主语置于句首, 而将真正的主语放在句尾。此时it只起先行引导作用, 本身无词义。
(2)不定式作主语的动作意义较强, 这种动作往往是“要发生的一次性动作”, 较具体; 动名词短语作主语往往是经常性、习惯性的动作, 此时谓语动词用单数。*Wrking with yu is a pleasure. 和你一起工作是一件乐事。
*He realized that t g n like this was wrng. 他意识到继续这样下去是错误的。*It takes me ten minutes t get hme frm my ffice . 我从办公室回家要花十分钟。
【即学活用】(1)_________ (cllect) stamps is his hbby. (2)It’s a waste f time __________(quarrel)with him. (3)Is it wrthwhile _______ (argue)with her?
quarrelling
(4)(句型转换)Ging t bed early is cnsidered t be a gd habit. →It is cnsidered t be a gd habit ________________.
【要点拾遗】limited adj. 有限的*It is a waste f limited resurces. 这是对有限资源的一种浪费。*My life is limited, but learning is limitless. 吾生也有涯, 而知也无涯。
*Dn’t take it fr granted that natural resurces can be used withut limit. 不要理所当然地以为自然资源是取之不尽, 用之不竭的!
【语块积累】(1)limitless adj. 无限制的; 无界限的limit v. & n. 限制limitatin n. 限制, 能力上的不足(2)set a limit t. . . 为……设置一个限制/极限withut limit没有限制, 无极限(3)limit sth. t将某物限制在……范围内
【即学活用】(1)单句语法填空①There is _______ (limit) time t finish the task. ②The rganizatin cmmittee set a limit __ the number f each delegatin. ③I knw my __________(limit), s I wn’t d the things beynd my ability.
(2) (2019·北京高考)With her talent and determinatin, it appears that the sky culd be the limit fr Alice Mre. 世纪金榜导学号译: ____________________________________________

Man Friday(Chapter 7) Fr tw years I never went anywhere withut my gun. I felt lnely and afraid, and had many sleepless nights. One night there was a very bad strm, and I thught I heard the sund f guns ut at sea.
The next mrning I lked ut, and saw a ship. It was lying n its side nt far frm the shre. Quickly, I put my little bat in the water and sailed ut t it. There were tw dead men n the ship, but n ne alive. The bdies f the ther sailrs were lst in the sea. I tk sme clthes and tls, and als a bx f Spanish
gld and silver mney. I was a rich man nw, but what use was mney t me? I culd nt buy anything with it. I wanted peple, a friend, smebdy t talk t. . . smebdy wh culd help me escape frm my island.
One mrning I wke up and made a plan. “I’ll try t catch ne f the prisners f the wild men, ”I said t myself. “He’ll be happy t be alive and perhaps he’ll help me t escape. ”I watched day and night, but fr a year and a half there were n bats.
Then ne day five bats came. There were abut thirty men and they had tw prisners. They made their fire n the sand and danced rund it. Then they killed ne f the prisners and began t ck their terrible meal. The secnd prisner waited under the trees, with tw men t watch him. Suddenly, the
prisner turned and ran. The tw men ran after him, but the ther wild men were busy rund the fire and did nt see what was happening.
The prisner ran like a wild gat, and sn I saw that he was cming near the bttm f my hill. As fast as I culd, I ran dwn the hill and jumped ut f the trees between the prisner and the tw wild men. I hit the first man with the wden end f my gun and he fell dwn, but I had t sht the secnd man. The pr prisner did nt mve. He was afraid f the nise f my gun.
I called t him and tried t shw him that I was friendly. Slwly, he mved nearer t me, but just then the first wild man began t get up frm the grund. Then the prisner spke and I understd that he wanted my swrd.
Hw happy I was t hear wrds again! I gave him my swrd, and at nce he cut ff the head f his enemy. Hurriedly, we hid the dead bdies under sme leaves, and then left quickly. I tk my prisner t my secret cave n the ther side f the island and gave him fd and drink. After that, he went t sleep.
He was a fine yung man, abut twenty-five years ld, tall and well-built, with a kind face and a nice smile. He had a brwn skin, black hair, bright eyes and strng white teeth. I decided t give him the name f ‘Man Friday’, because I first saw him n a Friday. When he wke up in the mrning, he ran ut t me. I
was milking my gats in the field, and he gt dwn n the grund and put his head near my ft. I understd that he was thanking me, and I tried t shw him that I was his friend. I began t teach him t speak English, and sn he culd say his name, ‘Master’, and ‘Yes’ and ‘N’. Hw gd it was t hear
a man’s vice again! Later that day we went back t my first huse. We went carefully alng the beach, but there were n bats and n wild men. Just bld and bnes all ver the sand. I felt ill, but Friday wanted t eat the pieces f men’s bdies which were still n the grund. I shwed him that this was terrible fr me,
and he understd. When we gt t my huse, I gave Man Friday sme trusers, and I made him a cat and a hat. He liked his new clthes very much. Then I made him a little tent t sleep in, but fr a few weeks I always tk my gun t bed with me. Perhaps Friday was still a wild man and wuld try t kill me in the night.
