Unit 4 Astronomy: the science of the stars.閱讀理解A(2018河南許昌模擬)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(設(shè)備) 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 (面團(tuán)) 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云南昆明適應(yīng)性檢測(cè))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.閱讀理解A語篇解讀美國(guó)宇航局出資125,000美元給一名3D技術(shù)專家,使其發(fā)明一種能夠使宇航員在需要時(shí)制作可口比薩餅的3D打印機(jī)。1.D推理判斷題。根據(jù)第一段尤其是第一段最后一句可推知作者提及宇航員在太空不能做某些事情是為了引出本文的話題,故答案為D項(xiàng)。2.C細(xì)節(jié)理解題。根據(jù)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.”可知答案為C項(xiàng)。3.D細(xì)節(jié)理解題。根據(jù)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.”可知本題答案為D項(xiàng)。4.B主旨大意題。文章是圍繞在太空用3D比薩打印機(jī)這一主題展開的,故本文題目應(yīng)為:宇航員不久將能夠享用熱比薩。故答案為B項(xiàng)。B語篇解讀本文為應(yīng)用文,介紹了加拿大多倫多的共享單車服務(wù)。5.D細(xì)節(jié)理解題。根據(jù)文中的“The Annual Membership is the best deal for the locals of Toronto and other frequent riders.”可知選擇D項(xiàng)。6.C推理判斷題。根據(jù)文中的“If you keep a bike for more than 30 minutes.and $7 for each additional 30 minutes after that.”可知,騎行兩個(gè)小時(shí)額外付費(fèi)為:$1.5+$4+$7=$12.5,故選C項(xiàng)。7.D細(xì)節(jié)理解題。由Employment Opportunities:(855)898-2498可知選擇D項(xiàng)。8.A細(xì)節(jié)理解題。根據(jù)文中“Find an available bike nearby, and get a ride code or use your member key to unlock it.”可知共享單車會(huì)員會(huì)得到一個(gè)騎行密碼一把會(huì)員鑰匙,故選A項(xiàng)。.語法填空語篇解讀文章介紹了作者喜歡秋天的原因。1.found根據(jù)空格前的went可知此處應(yīng)用一般過去時(shí)。 2.for樹葉顏色的變化是人們喜愛秋天的一個(gè)普遍原因,the reason for.意為“的原因”。3.differently句意:每棵樹對(duì)季節(jié)改變的反應(yīng)不同。空格處修飾動(dòng)詞reacts,故使用副詞differently。 4.trees根據(jù)謂語動(dòng)詞remain可判斷主語應(yīng)使用名詞的復(fù)數(shù)形式,故答案為trees。 5.is calledcall與句子主語構(gòu)成被動(dòng)關(guān)系,故答案為is called。6.reflection秋天是反思和對(duì)未來一年做準(zhǔn)備的時(shí)刻。介詞of后面需接名詞與preparation并列,故答案為reflection。7.an數(shù)詞18的發(fā)音以元音音素開頭,故使用不定冠詞an。 8.movingkeep doing sth.意為“一直做某事,繼續(xù)做某事”。9.to goencourage sb. to do sth.意為“鼓勵(lì)某人做某事”。10.whatdiscover后面為賓語從句,賓語從句中缺動(dòng)詞means的賓語,故使用連接代詞what。.短文改錯(cuò)Last Saturday I went to the library as usuallyusual.
