What are your retirement plans? Keep working? Get more exercise? Or learn something new? You may put them on hold. There’s a chance that, sooner or later, you might have to move further than you were thinking, as far as Mars (火星)．On Thursday, National Geographic will show the first ever Mars show home, giving earthlings an idea of what their life could look like on the Red Planet. Set in the notsodistant year of 2037, the iglooshaped structure could be the home of your future.It shows a house built using recycled spacecraft parts and Martian soil, called regolith, which has been microwaved into bricks. Some parts of the home are recognisable—kitchen, bedroom—but there are fundamental differences that are vital for human survival.As the Martian atmosphere is around one hundredth as thick as the Earth’s, people will need permanent shelter from the sun and society will move largely indoors. Most buildings will be connected by underground passage s and the houses won’t have windows. The homes will have simulated solar lighting, or natural light that has been bent several times.Walls will need to be 10 to 12 feet thick, to protect people from dangerous rays that can pass through six feet of steel, and a double airlocked entrance to keep the home under proper pressure.“We don’t think of our houses as things that keep us alive, but on Mars your house will be a survival centre，” says Stephen Petranek, author of How We’ll Live on Mars. This is not just the stuff of scifi. “Ten to twenty years from now there will certainly be people on Mars，” Petranek says.“We’ve had the technology for 30 years to land people on Mars, but we haven’t had the will，” Petranek says. “But two main factors have completely swung publicattitudes.”The private companies’ participation has forced government agencies to up their game, and influential films such as Gravity and The Martian have caught society’s eye.【解题导语】本文要紧对人类以后在火星上居住作了相关介绍。

高中英语Unit4GlobalwarmingSectionⅢGrammar—it的用法(Ⅱ)
Unit 4Global warming Section ⅢGrammar——it的用法（Ⅱ）一、it引导强调句型1．强调句型的基本结构：It is/was＋被强调部分＋that/who＋其他成分(1）此结构中it没有具体意义，只是引出被强调部分.（2）此强调句型只能强调主语、宾语、状语,不能强调谓语。
（3）强调时间状语、地点状语、原因状语等时要用that而不能用when, where，because.（4）被强调的成分是表示人的词时用who/that，而被强调部分是物时只能用that。
如：It is my mother that/who reminds me to get up on time every day。
每天都是我妈妈提醒我按时起床。
It was Mr Smith who/that/whom he turned to for help.他是向史密斯先生求助的。
It was in the museum that I first saw this old ancient vase。
我是在博物馆里第一次见到这个古花瓶的。
It is every Sunday that they get together to have a good time.每个星期天他们聚在一起来度过愉快的时光。
It was by train that they travelled to Tibet last summer。
去年夏天他们乘火车去了西藏。
2．强调句型的时态：(1）如果原句中谓语动词的时态是现在或将来时间范畴的时态（如一般现在时、现在进行时、现在完成时、现在完成进行时、一般将来时、将来进行时、将来完成时等)，强调句型的时态为It is＋被强调部分＋that/who＋其他成分。
（2)如果原句中谓语动词为过去时间范畴的时态(如一般过去时、过去进行时、过去完成时、过去将来时等）,强调句型的时态为It was＋被强调部分＋that/who＋其他成分。

人教版高中英语选修六 Unit4 Global warming-语法篇（学生版）Unit4 Global warming-语法篇_____________________________________________ __________________________________________________________________________________ _____________________________________1.掌握it在强调句中的用法；2.能够利用这个语法点进行遣词造句并运用到写作中；it的用法—强调句型一、强调句型的基本用法英语中常用的强调句型是：It is / was + 被强调部分(主语、宾语、状语) + that / who / whom + 其他部分。
一般来说，被强调部分指人时，用who或whom，其他情况用that，但that也可指人。
现在用强调句型强调下面这个句子的主语、宾语和状语。
She met John at Mary’s birthday party last Sunday.→It was she who / that met John at Mary’s birthday party last Sunday. (强调主语)→It was John Whom / that she met at Mary’s birthday party last Sunday. (强调宾语)6. 被强调部分若是句子的主语，that / who之后的谓语动词在人称和数上应与句子的主语保持一致。
eg：It is I that / who am your friend that will come to help you.二、强调句型的几种较为复杂的结构形式1.被强调部分为状语从句。
Eg: It was when Tom was eleven years old thathis talent for writing became obvious.2.被强调部分含有定语从句。
2017-2018高中英语Unit4GlobalwarmingSectionⅢGrammar-it的用法(2)新人教选修6
三、强调句应注意的问题 1．即使被强调成分是句中的时间状语、地点状语、原因状 语等，也不能用when, where, because等而要用that。 It was in front of the bank that the old lady was robbed. 老太太是在银行前面被抢劫的。
2．强调句型中的主谓一致——还原后，由真正的主语来确 定谓语动词的形式。
②It was a scientist called Charles Keeling, who made accurate measurements of the amount of carbon dioxide in the atmosphere from 1957 to 1997.
③They also agree that it is the burning of more and more fossil fuels that has resulted in this increase in carbon dioxide.
(2)It was/will be ... before ... “过……就……” It was not/will not be ... before ... “不久……就……”主 句中的 it 指时间，表语多是long, not long, three days, two weeks等表示“一段时间”的词或短语。试比较： It was three days before he went to Beijing. 三天后他就去了北京。 It was three days ago that he went to Beijing. 他是三天前去的北京。 此句是强调句，去掉“It was ... that”后句子仍然完整合理。
新人教版选修6高中英语Unit4Globalwarming4.2SectionⅡGrammar—it
Ⅲ.强调句型需要注意的问题 1．It is/was not until＋被强调部分＋that＋其他。 此句型可以和 not until 置于句首的倒装句相互转换。 He did not go to bed until his mother came back.(句型转换) →It was _____n_o_t_ _u_n_t_il____ his mother ____c_a_m_e_ __b_ac_k____ that he went to bed. →Not until his mother came back ___d_i_d___ he go to bed. 2．强调句的疑问句形式在句中充当宾语从句时，要用陈述语序。
总结：以上各句都使用了 it is/was...that/who 结构，该结构若去掉 不影响句子的完整性，这样的句型被称为“___强__调___句型”。该句型
中 it is/was 与 that/who 中间部分是被强调的部分。当被强调的部分是 物时，该句型用__th_a_t____；当被强调的部分是人时，则用_w_h_o__或__t_h。at
Ⅱ.强调句型的疑问句形式 1．一般疑问句形式。 Is/Was＋it＋被强调部分＋that/who＋其余部分？ 昨天你是在公园见到汤姆的吗？(汉译英)
__W_a_s_i_t_in__th_e__p_a_rk__th_a_t_y_o_u__m_e_t_T_o_m__y_e_s_te_r_d_a_y_?__________________ 2．特殊疑问句形式。 特殊疑问词＋is/was＋it＋that＋其余部分？ 昨天你是在哪里见到汤姆的？(汉译英)
