Today Chinese scientists have claimed victory in their battle to improve public restrooms, introducing a bacterial spray that can almost get rid of all the bad smell. First, a set of six types of bacteria work to break down the smelly compounds and then a perfume made from orange skin lightly scents (使芳香) the air. The “smell­free toilet” study from the Chinese Academy of Science was declared the “ultimate” cure to an_“urgent”_national_issue.

　　“Five scientists have worked on this from 2011 to the beginning of this year，” said Dr. Yan Zhiying, a bacteriologist with the academy's Chengdu Institute of Biology, adding that they had spent ￡140,000 on the project.

　　“Some local government officials here visited a sewage (污水) plant and saw that the treatment technology had come from Japan. They wanted a home­grown solution so they asked us to work on it，” he added. “We obtained bacteria from all types of waste from humans, pigs, chicken and ducks, and we tested our compounds one by one，” he said. “The smells coming out of public toilets, or trash cans, are made up of more than 160 different compounds，” he explained, adding that their bacteria spray can change and absorb many of them.

　　He boasted that the Chinese formula (配方), which costs only around ￡5 per liter, has no side effects and can be used to remove any bad smell.

　　文章大意：這是一篇說明文，介紹的是中科院成都生物研究所發(fā)明了一種細(xì)菌噴灑劑，能夠除去各種異味。

　　13.The underlined words “ward off” in Paragraph 2 can be replaced by ________.

　　A.keep out B.take out

　　C.give out D.come out

　　答案：A　詞義猜測題。根據(jù)畫線詞前的find boxes to cover their noses可知用盒子把鼻子蓋住是為了擋住難聞的氣味。keep out意為“阻止……進(jìn)入”，符合語境。take out意為“拿出”，give out意為“分發(fā);發(fā)出”，come out意為“出版;被揭曉”，均不符合語境。

　　14.The underlined phrase “an ‘urgent’ national issue” refers to ________.

　　A.the treatment of sewage

　　B.a horrifying experience

　　C.the bad smell of public toilets

　　D.the 160 smelly compounds

　　答案：C　詞義猜測題。全文的焦點是中國公廁的臭味難聞，現(xiàn)在中科院正針對這個問題進(jìn)行研究，顯然這個全國性的緊急問題就是廁所的臭味。故選C項。

　　15.Which has not been mentioned as an advantage of the bacteria spray?

　　A.Low price. B.No side effects.

　　C.Removing bad smells. D.Beautiful design.

　　答案：D　細(xì)節(jié)理解題。依據(jù)文章最后一段He boasted that the Chinese formula, which costs only around ￡5 per liter, has no side effects and can be used to remove any bad smell. 可知，這個除味噴劑的優(yōu)點有：價格低、沒有副作用、可去除臭味。文中沒有提到D項(設(shè)計美觀)。故選D項。

　　16.Which can we infer after the spray is used in toilets in China?

　　A.People needn't use flushing toilets.

　　B.A perfume is given off in the air.

　　C.Tourists' complaints will be reduced.

　　D.Bacteria break down smelly compounds.

　　答案：C　推理判斷題。根據(jù)第一段內(nèi)容可知，三分之一的游客投訴是關(guān)于公廁的臭味問題，下文講到中科院已經(jīng)研制出一種除味噴劑，可以去除廁所的異味。由此可以推斷，這種噴劑在中國的公廁中噴灑后，游客的投訴應(yīng)該會減少。

　　There are many places to go on safari (觀賞野生動物) in Africa，but riding a horse through the flooded waters of Botswana's Okavango Delta must rank as one of the world's most exciting wildlife journeys.

　　Several safari camps operate as the base for this adventure，providing unique rides twice a day to explore deep into the delta.The camps have excellent horses，professional guides and lots of support workers.They have a reputation for providing a great riding experience.

　　The morning ride，when the guides take you to beautiful，shallow lakes full of water lilies，tends to be more active.It is unlike any other riding experience.With rainbows forming in the splashing water around you and the sound of huge drops of water bouncing off your body and face，it is truly exciting.You are very likely to come across large wild animals, too.On horseback it is possible to get quite close to elephants，giraffes and many other animals.The sense of excitement and tension levels rise suddenly though，as does your heart rate，as you move closer to them.

　　In the evening，rides are usually at a more relaxed and unhurried pace，with golden light streaming across the grassy delta and the animals coming out to eat and drink.Sedate though they are，rides at this time of day are still very impressive.As the sun's rays pass through the dust kicked up by the horses，the romance of Africa comes to life.

　　Back at the camp you can kick off your boots and enjoy excellent food and wine.Looking back on your day，you will find it hard to deny that a horseback safari is as close as you will ever come to answering the call of the wild.
