19.Need to buy something?Why go to a store?Buy it on the Internet!Need it now?Why wait?Ask for next-day delivery!Each day,more and more people try online shopping.In fact,online sales have doubled in the last ten years.But not everyone is excited.Some scientists now say that online shopping is bad for the environment.
People are surprised to hear this."They think,‘I don't need to drive,and the business doesn't need to build a store,so there will be less pollution,'"says Nuria Prost,an environmental scientist."But it is not so simple.In fact,online shopping is wasteful.It also adds to air pollution."
In truth,the Internet is not always as good a friend to the environment as it seems.For example,most people thought that the Internet would help offices use less paper and other materials.But paper use increased by 33percent between 1986and 1997."Online shopping could have similarly negative effects,"says Nevil Cohen,a professor of environmental science.
Part of the problem is what people are buying these days.In the past,people bought things on the Internet that did not require much packing material,such as books and clothing.But now people also shop online for large,heavy products such as televisions,computers,and furniture.These products need to be packed in large amounts of plastic and paper.This creates a lot of waste.
Another problem caused by online shopping is air pollution.When customers buy products and ask for next-day delivery,companies often have to send them by air.Airplanes use much more fuel than cars and produce more carbon dioxide (CO2).When people buy a lot of different things from different online businesses,this creates even more travel by airplane.
Online product returns are also a problem.For example,an online shoe store may allow customers to return shoes without extra pay if they are the wrong size.This doubles the packing material and number of airplane trips required to sell one pair of shoes.
"If people want to protect the environment,they need to think before they shop,"says Prost."People need to ask themselves:Is this exactly what I want?Do I really need it tomorrow,or can I wait?"Online stores can also charge(收費(fèi))customers for returns.This may make people shop more carefully."Online shopping is fast and easy,"says Prost,"but we can't forget the negative effects it has on the environment."

分析 這篇文章主要介紹了越來(lái)越多的人嘗試網(wǎng)上購(gòu)物.事實(shí)上,網(wǎng)上銷售在過(guò)去的十年里翻了一番.但并不是每個(gè)人都很興奮.一些科學(xué)家現(xiàn)在認(rèn)為,網(wǎng)上購(gòu)物對(duì)環(huán)境有害.人們聽到這個(gè)很驚訝,他們認(rèn)為,"我不需要開車,業(yè)務(wù)交易不需要建立一個(gè)商店,所以將會(huì)有更少的污染,"環(huán)境科學(xué)家努力亞說(shuō),"但這并不是那么簡(jiǎn)單.事實(shí)上,網(wǎng)上購(gòu)物是浪費(fèi).它也增加了空氣污染."事實(shí)上,互聯(lián)網(wǎng)并不總是看起來(lái)對(duì)環(huán)境那么好."網(wǎng)上購(gòu)物方便快捷,"普羅斯特說(shuō),"但是我們不能忘記對(duì)環(huán)境的負(fù)面影響."
解答 答案:48.D 細(xì)節(jié)理解題.根據(jù)But now people also shop online for large,heavy products such as televisions,computers,and furniture.These products need to be packed in large amounts of plastic and paper.This creates a lot of waste.但是現(xiàn)在人們也網(wǎng)上購(gòu)物對(duì)大型、重型產(chǎn)品,如電視,電腦,和家具.這些產(chǎn)品需要大量的塑料和紙張,會(huì)造成很多的浪費(fèi).可知大型、重型產(chǎn)品需要包裝材料,會(huì)造成很多的浪費(fèi).故選D.
49.C 細(xì)節(jié)理解題.根據(jù)When customers buy products and ask for next-day delivery,companies often have to send them by air.當(dāng)顧客購(gòu)買產(chǎn)品,要求第二天交貨,公司往往通過(guò)空運(yùn)發(fā)送它們.故 選C.
50.B 細(xì)節(jié)理解題.根據(jù)."Online shopping is fast and easy,"says Prost,"but we can't forget the negative effects it has on the environment."."網(wǎng)上購(gòu)物方便快捷,"普羅斯特說(shuō),"但是我們不能忘記對(duì)環(huán)境的負(fù)面影響."可知 Prost認(rèn)為網(wǎng)購(gòu)會(huì)增加環(huán)境污染.故選B.
51.C 整篇文章主要介紹了網(wǎng)購(gòu)其實(shí)沒(méi)有使環(huán)境保護(hù)和清潔,反而增加環(huán)境污染,對(duì)環(huán)境造成一定的影響.所以標(biāo)題應(yīng)該是 網(wǎng)購(gòu)真的是一種清潔的購(gòu)物方式嗎?故選C.
點(diǎn)評(píng) 在通讀全文的基礎(chǔ)上,根據(jù)全文大意,展開邏輯思維,瞻前顧后,認(rèn)真觀察選項(xiàng),仔細(xì)推敲,確定最佳答案.
