這篇短文主要講述了未來的汽車。大約40年前,美國科學(xué)家開始研發(fā)無人駕駛汽車。最新最有名的無人駕駛汽車是由谷歌公司2009年研發(fā)的。中國科學(xué)家也成功的研發(fā)出了一種無人駕駛汽車。并完成長沙到武漢的行程。無人駕駛汽車安全嗎?一項最新的研究表明機器人比人類駕車安全。如果街道上只有10%的無人駕駛汽車,每年會挽救1千條生命。如果街道上90%的交通工具是無人駕駛汽車,那么一年會挽救21,700條生命。然而,無人駕駛汽車很昂貴,每輛車的造價大約10萬。所以在不久的將來這種車不會非常流行。

怎樣才能做對英語的補全短文
1、做題總思路:
從分析題型知道,它只不過是要找出各選項在原文的出處而已,并且這個出處已經(jīng)確定了5個填充處給予選擇。
針對這類題的要求和特點,我們可以運用綜合分析排除法來選出正確的答案:一是不“符合語法知識”的排除,二是不“符合邏輯結(jié)構(gòu)”的排除,三是不能使填充處“前后內(nèi)容銜接、意思連貫”的排除。因此,做這類題的重點,一是選項句子,而選項句子重點是它的中心詞,包括:名詞、代詞和連接詞,這三種詞是我們必須重視的,也是我們了解該選項句子意思,運用上述三種方法的前提,二是填充處的前后段或前后句子,弄清楚這個填充處所在位置的意義以及其前后段或前后句子的邏輯關(guān)系和內(nèi)容意思,也是運用上述方法的前提。
2、做題步驟:
(1)第一步:找出各選項句子中心詞:名詞、代詞和連接詞,了解這句子的大概意思(要該選項中劃出其中心詞并簡要寫其大意)。建議:如果有點英語基礎(chǔ),在做這一步之前最好快速游覽一個全文,了解全文大概是講什么的。然后,根據(jù)各選項句子的大概意思,初步設(shè)想一下它們最有可能的位置和彼此順序。
(2)第二步:按順序了解某一個填充處前后段或前后句子的邏輯關(guān)系和大概內(nèi)容意思。這也是類似找中心句子與中心詞的方法,找出前后段最接近填充處的句子的中心詞(名詞、代詞和連接詞),或者找出填充處前后句子的中心詞,了解其大概意思和相互間的邏輯關(guān)系。
(3)第三步:把選項句子中心詞及其大意與填充處前后段或前后句子的邏輯關(guān)系及大意進行對照,運用下述的做題技巧,綜合分析排除,確定最有可能的選項或直接確定答案;并把確定了的答案劃去和把最有可能的選項(A、B、C…)寫到填充處,無論能否確定答案,都要接著往下做下一個填空處,以如類推。因為這類題是5選5,基本上是一個蘿卜一個筐,每個選項最多只能用一次,并且都必須用上,所以,不能確定最后唯一答案時,基本上可以通過做其它的填充處,甚至到最后把所有的填充處綜合起來推敲,也可以確定各填充處的答案,因此,不要急于求成,困死在某一個填充處上。
(4)第四步:利用綜合分析排除法,最后理順并最終確定各選項的所有位置。確定了所有答案后,把各選項對號入座,進行檢查和印證。

China and Western countries may have different cultural beliefs about certain animals, but when it comes to pigs, somehow we have the same idea – that pigs are ugly and lazy.
But the truth is that pigs do have some finer qualities. And maybe there’s no better time to clear their names than now, with the arrival of the Year of the Pig on Feb 5 this year.
For starters, science long ago proved that pigs aren’t stupid at all. According to a research, “pigs are mentally (精神) and socially like dogs and chimpanzees.” They like to play. They can remember things for a long time. And they can tell who treat them well and who don’t.
There are lovable pig characters in cartoons too. Peppa Pig, a UK animated television series that begin in 2004, has now become one of the most popular cartoons in 180 countries and areas. The four members in the cartoon’s pig family teach children from all over the world to get on well with friends. Their daily stories show that family members are the most valuable persons to cherish (珍惜). And in China, the adventures of McDull, a piglet who works hard towards his dreams even though he keeps failing, have been made into films since 2001. McDull is slow and patient, and not afraid of repeated failures. He has a heart of gold.
Perhaps these are the qualities of pigs to keep in mind when we celebrate this Chinese New Year—their intelligence (智力), cuteness, patience and innocence.
Traditional ideas | China and Western cultural beliefs somehow 【1】 an agreement on pigs. | |
Truth about pigs | Pigs’ intelligence is 【2】 to that of dogs’ and chimpanzees’. Pigs have long-term memories. Pigs can tell who treat them well and who don’t. | |
Pig characters in cartoons | Peppa Pig | Her family teach kids friendship and the 【3】 of family. |
McDull | He works hard to 【4】 his dream. | |
New impressions | Pigs are clever, cute, 【5】 and innocent. |

【題目】 Have you ever heard of e-waste(electric waste),which can be produced every day?How do you deal with your computers, MP4 players and mobile phones when they’re broken or you want a new one?
Most people just throw them away. With the development of electric industry, e-waste pollution has become a serious problem. According to the United Nations, in 2014, people around the world produced 41.8 million tons of e-waste and only recycled 6.5 million tons. The US was the biggest waster, producing 7.1 million tons. China came second, with 6 million tons.
It’s important to pay attention to e-waste. It can either be valuable or harmful, depending on how we deal with it. E-waste is a valuable urban mine(城市礦藏). The value of the metals, like gold and silver in the waste around the world, is amazing. And the metals can be reused. But if people throw them away, the toxic chemicals(有毒化學(xué)物質(zhì))can get into the earth or air, affecting the environment and people’s health.
Apple, for example, now recycle people’s used products in China when they are buying new ones. The company will test and repair the used ones and sell them at lower prices. To help reduce(減少)e-waste, we can also take computers and phones to see if companies offer recycling programs.
