unit 3 inventors and inventions reading课时作业.阅读理解a(2018吉林百校联盟联考)a new “smart bin” could mean the end of environmentconscious families spending hours sorting tins，cartons，bottles，and cardboard for recycling.the invention，which can help sort rubbish into recycling categories without needing people to operate.it is being trialled in poland and is set to go on sale in uk within a few years.the bin，designed by startup company bin.e，recognizes different types of waste via a system positioned inside the bin which uses sensors，image recognition and artificial intelligence.once waste is placed inside，the camera and sensor identify its type and place it in one of the smaller bins.then it compresses the waste so it occupies less space.it is thought that the bin could be stocked by department stores such as john lewis，which said it is introducing more new hitech recycling bins.matt thomas，a buyer at john lewis，gave us the reason，“weve recently seen a jump in specialist bins sales，with a 25 percent increase in the last few months alone.we have noticed our customers are becoming more and more focused on sustainability.in response to this demand，we are really excited to introduce a smart bin this autumn/winter seasondesigned to make recycling more efficient and functional for the everyday home.”bin.es official release on the market will take place in 2018.however，at first only a larger version designed for offices will be available.the office bin will sell at 430 while customers will need to pay a 107 subscription fee for an accompanying smartphone app，which hooks them up with collection services.a spokesman at bin.e said that home version of the bin will be cheaper and will not include a monthly payment.they added：“after the office version，we plan to create an outdoor version and later the home version.we decided to go for the outdoor version for public areas first because it is more difficult to organize an efficient waste segregating system than in our homes.”1.what do we know about a new “smart bin” from the first paragraph?a.it works automatically.b.it has been used widely.c.it is easy to operate.d.it is very expensive.2.what does the underlined word “it” in paragraph 3 refer to?a.the waste. b.the camera.c.the bin. d.the sensor.3.why is john lewis introducing more new hitech recycling bins?a.to change peoples behaviour.b.to satisfy increasing demands.c.to popularize new technology.d.to make them more famous.4.where will the first version of new “smart bin” be used according to bin.es official?a.at home.b.in the supermarket.c.in the open air.d.in the office.b(2018广西南宁八中摸底)every day，people come into contact with thousands of chemicals.these chemicals are said to be harmless to human health.in fact，the chemicals are considered so safe that we wash with them.we put them on our bodies and even our faces.other chemical products are used throughout our homes.by the time you walk out of your front door，you have already been exposed to thousands of chemicals.on its own，each chemical seems harmless.but in combination with other chemicals，they may become deadly.that is the finding of a twoyear study by a highprofile(高调的) task force of scientists.the task force was told to investigate the cancercausing possibility of chemical mixtures.linda gulliver was one of the 174 scientists on the task force.their job was to study the cancercausing potential of 85 chemicals.all 85 are said to be common in the environment.ms gulliver explains that chemicals have the potential or ability to form dangerous mixtures.even simple minerals can become dangerous when mixed with chemicals found in plastics or beauty products.working in groups，the scientists explored how different chemical mixtures could lead to cancer.ms gullivers team looked at the ability of different combinations to support the increase of malignant(恶性的) human cells.she says the current way to identify whether chemicals cause cancer is to test them one at a time.this method leads，she adds，to a long list of supposedly “safe” chemicals.she and her team say that approach needs to change.“we definitely need certain research.to find out what mixtures of chemicals would be more harmful than others; what groups of chemicals，when together，would produce more harmful effects.and at the moment，that is not known.”an estimated one in five cancers has been linked to chemical exposure.it may turn out that the cancercausing villain(恶人) is not a single chemical at all.5.what effect may one single chemical have on us according to the text?a.it may destroy our body.b.it may not cause danger to us.c.it may let us suffer from cancer.d.it may let our body make a change.6.what can we learn about ms gullivers research?a.she has found 85 cancercausing chemicals.b.she has found reasons for five kinds of cancers.c.she has found that only one chemical can cause cancer.d.she is not sure what mixtures of chemicals are more harmful.7.according to the text，we can infer that the study .a.is just wasting time and money b.is still in need of great effortsc.will cause panic in public d.will be resisted by the public8.what is the best title for the text?a.mixtures of safe chemicals may cause cancerb.being exposed to one chemicals is dangerousc.how mixtures of safe chemicals come into being?d.what is the real cause for cancer?.七选五(2018吉林长春期中)many times we tend to use our hands to explain our needs and thoughts. 9 so you must be cautious when using hand gestures in communication.hand gestures are a way of communicating with others and conveying your feelings.these gestures are most helpful when one is speaking to someone with no language in common.the meanings of hand gestures in different cultures may translate into different things. 10 former president george w.bush had to face a major faux pas(失礼) during a visit to australia.he tried to signal a peace sign by waving the twofinger or vsign at the crowd.you may think of this as a simple gesture，but he committed a major error. 11 the meaning of this hand gesture in australia was asking the crowd to screw themselves，a rude expression used to show youre very angry！ 12 therefore，it is very important to understand the meanings of gestures before you travel to different countries. 13 those considered as good gestures in one country may be termed as offensive gestures in some countries.so，if you are a frequent flier to different countries，improve your communication skills by learning the meaning of hand gestures.a.here is a very common example.b.instead of his palm facing outwards，it faced inwards.c.the great man received warm welcome by the australians.d.we communicate not only by words，but by hand gestures as well.e.a serious error committed by the then most powerful man in the world.f.but the same hand gesture may mean something quite offensive to a person from a different cultural background.g.before you communicate with people in different cultures，you need to understand the meaning of gestures.语法填空(2018安徽合肥联考)i was traveling in a small place in new york.that place had no taxi for a short 14.
