Small and round transparent water bottles filled with natural water could help provide a solution to London's plastic waste problem,according to Skipping Rocks Lab,the company in the British capital that produces them.They added that the balls have been made of plant and seaweed extracts and will decompose（分解）after four to six weeks if not consumed.

With many cities struggling to get rid of vast numbers of used plastic water bottles,the 'Ooho' has begun to meet the thirst of consumers in San Francisco and London.A report published last Thursday said more than 4,000 plastic bottles had been removed from the River Thames in a month last year,proving the scale of the waste problem.

"We think Ooho may not be the solution for all the applications that plastic bottles have,but definitely for short term consumption it could be a solution,"said Rodrigo,the founder of Skipping Rocks Lab.In a trial near London Bridge last Wednesday,Ooho drew a mixture of surprise,amusement and delight among those who sampled them. London's city assembly said Ooho was a step forward."It could be part of the solution but not the only solution.You also need to be able to refill bottles at railway stations for example,"said Leonie Cooper,the Chair of the assembly's environment committee.

The company aims to target,among other consumers,marathon runners,who will be able to eat the Oohos mid-race without concerns about the environment.It is also considering sealing alcohol for a whole new market. "People see these small round bubbles and they just think 'shots'.So that's definitely something we're looking at,"said Skipping Rocks Lab Chief Operating Officer Lise."We have sealed alcohol,we want to perfect it,and hopefully this will be the great change of the future."

1.'Ooho' can help solve the plastic waste problem because .

A. it is small and transparent B. it is filled with natural water

C. it is made of plant and seaweed D. it can disappear some time later

2.How is Rodrigo's comment on 'Ooho'?

A. Subjective. B. Unreal.

C. Objective. D. Ridiculous.

3.In which column can we find the text?

A. Technology and Invention. B. Health and Medicine.

C. Industry and Economy. D. Tourism and Development.

Do you know how to pick a good book you’ll really like? Here are some tips.

Start With Your Interest. 1. . You can pick something that you love to read, not for school. They can be ancient martial (武術(shù)) arts, computers, or fashion design. You name it, there are books about it.

What’s Your Type? Do you prefer fiction or nonfiction (or both)? Fiction books, like novels, can transport you to another world or help you imagine something beyond your own experience. Nonfiction books give you the who, what, when, and why of something. 2. . Many of them read like novels from start to finish.

Read the description. The reviews and quotes on the back and inside covers of many books give you an idea of what the book is about. They can also help you pick future books, too. If you find a book you really like, take a minute to read the quotes and see which authors praised the book. 3..

Find a Family Favorite. Which book did your mother love best when she was at your age? 4.. Find out and give them a read — then you can share your thoughts about the book.

Finally, you’ll probably enjoy what you’re reading a lot more if you find a quiet place and make time for the book. 5. You can put on some good music, get yourself some tea and let yourself be carried away by the book. You’ll see that time does fly when you’re reading something you love!

A. How about your brothers and sisters?

B. They tell stories using facts — but that doesn’t mean they’re boring.

C. Reading is a good way to improve your English.

D. Most reading is best enjoyed when you can concentrate (全神貫注) on it.

E. Often, they’ll have similar styles and you might find books you like by those authors, too.

F. So you should read as much as possible when you are free.

G. Reading on your own isn’t like reading for school.

【四川省成都市第七中學(xué)2017屆高三二診】C

On 8th March this year, events marking International Women’s Day (IWD) were held in many countries around the world. In most countries the events have a political tone: they tend to celebrate the advances women have made towards economic, social and political equality with men, and to press for change in those areas of life where there is still progress to be made.

In other countries, meanwhile, 8th March is traditionally more about expressing an appreciation of women: it is a day on which men give presents to their wives, girlfriends and mothers, and it therefore has some similarities with St Valentine’s Day and Mother’s Day.

Back in 1911, the first IWD events in Austria, Denmark, Germany and Switzerland were certainly political. They were protests by women against forms of gender discrimination that would now be unthinkable in most parts of the world: almost nowhere were women allowed to vote, and Finland was the only country with any female members of a national parliament. The general expectation worldwide, across different continents and cultures, was that women would spend their lives largely in the home, devoting themselves to looking after their husbands and children. The rate of women who had paid employment was far lower than today, and when women did go out to work they typically earned very little, meaning they were economically dependent on men.

A century later, gender inequality in employment—particularly pay inequality—is still one of the hottest issues IWD tries to draw attention to: it remains common, of course, for women to earn less than men for doing exactly the same job.

Limited educational opportunities (there are many countries in which girls generally stay fewer years in school than boys) and domestic violence towards women have also been highlighted by events surrounding IWD in recent years.

And yet, as the IWD website notes, As just one example, to return to the issue of women elected to office, the change over the last hundred years has been significant. Since 1911, when the small group of women in the Finnish parliament (nineteen of them, to be exact) were the only females in public office worldwide, the governments of more than fifty different countries have been led by women. In 2011, at least one country in every continent has a female leader, including high-profile examples such as Brazil (Dilma Rousseff), Germany (Angela Merkel) and Australia (Julia Gillard).

1.According to the passage, which of the following is true?

A. 100 years ago, women were not allowed to work outside.

B. IWD is equal to St Valentine’s Day and Mother’s Day in some countries.

C. Finland was the first country with female employment.

D. Pay inequality is a hot issue for IWD.

2.Which word below is closest in meaning to the phrase “press for” in Paragraph 1?

A. prevent B. urge C. express D. want

3.Which of the following is the missing sentence in the first line of the last paragraph?

A. distinctive differences do exist between men and women

B. the achievements are beyond people’s expectations

C. there’s still a long way to go to achieve the set goals

D. alongside the ‘negatives’ there are plenty of ‘positives’

4.We can conclude from the passage that .

A. the progress in gaining equality in the last century seems to be too slow

B. the concept of equal pay for equal work is completely accepted in practice

C. much has been achieved in gender equality, but still there is space for improvement

D. one or two female leaders can’t stand for women’s social status on the whole

The most widespread fallacy (謬論)of all is that colds ire caused by cold. They are actually caused by viruses passing on from person to person. You catch a cold by coining into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever But they do not. And in the isolated Arctic Regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.

During the First World War soldiers who spent long periods in the trenches(戰(zhàn)壕), cold and wet, showed no increased tendency to catch colds.

In the Second World War prisoners at the Auschwitz concentration camp，naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty rooms. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.

If then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter. Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.

1.The writer offered examples to support his argument

A. 4 B. 5

C. 6 D. 7

2.Which of the following is TRUE according to the passage?

A. The Eskimos suffer from colds from time to time.

B. Colds are not always caused by cold.

C. People suffer from colds just because they like to stay indoors.

D. A person may catch a cold by touching someone who already has one.

3.Arctic explorers may catch colds when they are .

A. working in the isolated arctic regions

B. writing reports in terribly cold weather

C. free from work in the isolated arctic regions

D. coming into touch again with the outside world

4.Volunteers taking part in the experiments in the Common Cold Research Unit .

A. suffered a lot B. never caught colds

C. often caught colds D. became very strong

5.The passage mainly discusses .

A. the experiments on the common cold

B. the fallacy about the common cold

C. the reason and the way people catch colds

D. the continued spread of common colds
