Unit 4 Astronomy: the science of the stars.阅读理解A(2018河南许昌模拟)While astronauts in space get to do many exciting things,they miss out on ordinary things that we all take for grantedbeing able to walk on firm ground,hanging out with family and digging into a slice of hot steaming pizza.Though not much can be done about the first two things,there may soon be a solution to the third one,thanks to this cool 3D pizza printer!About a year ago,NASA offered $125,000 to Anjan Contractor,a 3D technology expert,to build a device(设备) that would allow astronauts to make pizza on demand.The mechanical engineer promised that his invention would produce pies in large quantities that looked,tasted and even smelled like pizza made in mon ovens.Late last year,the engineer presented a video of his first prototype(原型) that begins by creating a single slice of dough (面团) that is cooked and printed at the same time.Then es the tomato “sauce”a mix of tomato powder,oil and water and finally,a protein slice that resembles cheese.While the video doesnt show the baking process,the inventor says that once the pizza is printed,it can be ready to be consumed in 7 seconds.While the pie in the video looks delicious enough to attract any pizza lover,Anjan Contractor is far from ready for astronauts.Thats because he still has to find a solution to make the food container in the printer last for 30 years.Though that may sound unrealistic,actually it is not.Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients(配料) and then they are reduced to the powder form.This,as you can imagine,will not be so easy.But,while the printer may not be ready for space,it certainly looks ready enough for people on earth.Hopefully,NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!1.Why does the author mention the things that astronauts in space cannot do?A.To ask us not to take mon things for granted.B.To show they live a difficult life there.C.To show their life is boring in space.D.To introduce the topic of the text.2.NASA offered $125,000 to Anjan Contractor mainly to.A.create some new type of 3D printerB.attract more panies to work for NASAC.help astronauts in space enjoy fresh pizza one dayD.produce pizza in large quantities to earn great profits3.The biggest challenge that Anjan Contractor is faced with now is probably that.A.he has no money left to go on with his researchB.the pizza doesnt seem appetizing to pizza loversC.he has no way to make pizza that can last for thirty yearsD.he cannot make the food container last for decades4.Whats the best title of the passage?A.NASA is trying its best to help astronauts eat better B.Astronauts may soon be able to enjoy steaming hot pizzaC.NASA is working on making pizza for mon peopleD.A 3D pizza printer has been used to make pizzaB(2017云南昆明适应性检测)Bike Share Toronto is the citys official bike share program designed to give locals and visitors a fun, affordable and convenient alternative to walking, taxis, buses and the subway.

At about noon, I was enjoying my reading near a lake while suddenly I hear someone crying for help. I went to see what was happened. I was shocking to find a little child struggling in the water in the distance while many peoples were standing by without doing anything. Without any hesitation, I had pushed through the crowd as I took off my coat, but jumped into the water quickly. I managed to reach him and carried him back to safety. To his great relief, the kid was saved. I was proud what I had done. I hope everyone can give a hand when someone else is in need. 答案精解精析.阅读理解A语篇解读美国宇航局出资125,000美元给一名3D技术专家,使其发明一种能够使宇航员在需要时制作可口比萨饼的3D打印机。1.D推理判断题。根据第一段尤其是第一段最后一句可推知作者提及宇航员在太空不能做某些事情是为了引出本文的话题,故答案为D项。2.C细节理解题。根据第二段中的“About a year ago,NASA offered $125,000 to Anjan Contractor,a 3D technology expert,to build a device that would allow astronauts to make pizza on demand.”可知答案为C项。3.D细节理解题。根据第四段中的“Thats because he still has to find a solution to make the food container in the printer last for 30 years.”可知本题答案为D项。4.B主旨大意题。文章是围绕在太空用3D比萨打印机这一主题展开的,故本文题目应为:宇航员不久将能够享用热比萨。故答案为B项。B语篇解读本文为应用文,介绍了加拿大多伦多的共享单车服务。5.D细节理解题。根据文中的“The Annual Membership is the best deal for the locals of Toronto and other frequent riders.”可知选择D项。6.C推理判断题。根据文中的“If you keep a bike for more than 30 minutes.and $7 for each additional 30 minutes after that.”可知,骑行两个小时额外付费为:$1.5+$4+$7=$12.5,故选C项。7.D细节理解题。由Employment Opportunities:(855)898-2498可知选择D项。8.A细节理解题。根据文中“Find an available bike nearby, and get a ride code or use your member key to unlock it.”可知共享单车会员会得到一个骑行密码一把会员钥匙,故选A项。.语法填空语篇解读文章介绍了作者喜欢秋天的原因。1.found根据空格前的went可知此处应用一般过去时。 2.for树叶颜色的变化是人们喜爱秋天的一个普遍原因,the reason for.意为“的原因”。3.differently句意:每棵树对季节改变的反应不同。空格处修饰动词reacts,故使用副词differently。 4.trees根据谓语动词remain可判断主语应使用名词的复数形式,故答案为trees。 5.is calledcall与句子主语构成被动关系,故答案为is called。6.reflection秋天是反思和对未来一年做准备的时刻。介词of后面需接名词与preparation并列,故答案为reflection。7.an数词18的发音以元音音素开头,故使用不定冠词an。 8.movingkeep doing sth.意为“一直做某事,继续做某事”。9.to goencourage sb. to do sth.意为“鼓励某人做某事”。10.whatdiscover后面为宾语从句,宾语从句中缺动词means的宾语,故使用连接代词what。.短文改错Last Saturday I went to the library as usuallyusual.
