课时规范训练(三十七)Ⅰ.阅读理解A(2016·高考全国乙卷)I am Peter Hodes，a volunteer stem cell courier.Since March 2012，I've done 89 trips—of those,51 have been abroad.I have 42 hours to carry stem cells (干细胞) in my little box because I've got two ice packs and that's how long they last.In all，from the time the stem cells are harvested from a donor (捐献者) to the time they can be implanted in the patient，we've got 72 hours at most.So I am always conscious of time.I had one trip last year where I was caught by a hurricane in America.I picked up the stem cells in Providence，Rhode Island，and was meant to fly to Washington then back to London.But when I arrived at the checkin desk at Providence，the lady on the desk said：“Well，I'm really sorry，I've got some bad news for you—there are no flights from Washington.” So I took my box and put it on the desk and I said：“In this box are some stem cells that are urgently needed for a patient—please，please，you've got to get me back to the United Kingdom.”She just dropped everything.She arranged for a flight on a small plane to be held for me，rerouted(改道) me through Newark and got me back to the UK even earlier than originally scheduled.For this courier job，you're consciously aware that in that box you've got something that is potentially going to save somebody's life.【语篇导读】本文是一篇记叙文。

BFor foreigners, entering a public toilet in China can be a horrifying experience. In the 1990s, a third of all complaints to tourism officials in Beijing concerned the design, and the bad smell of public toilets.China has battled smelly toilets for at least 2,000 years. In the Kingdom of Wei (220—266 A．D.), visitors to the palace bathrooms would find boxes to cover their nose and ward_off unpleasant smells. Both flushing (冲水) toilets and toilet paper were invented in China, however, only for the use of the emperor.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 ofwaste 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.4．The underline d words “ward off” in Paragraph 2 can be replaced by ________.A．keep out B．take outC．give ont D．come out5．The underlined phrase “an ‘urgent' national issue” refers to ________.A．the treatment of sewageB．a horrifying experienceC．the bad smell of public toiletsD．the 160 smelly compounds6．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.7．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.【语篇导读】这是一篇说明文，介绍的是中国科学院成都生物研究所发明了一种除臭喷洒剂，能够除去厕所的各种异味。
