   Trying to fight against the nation's food waste problem,Denmark opened the world's first supermarket that sells expired(到期的)or damaged products.

Ever since it was opened in Copenhagen,people have been standing in line outside WeFood for a chance to buy discounted items that would otherwise have ended up being rubbish because of damaged packing or very short use-by dates. Food,cosmetics,and other household items at WeFood are priced at least 30% to 50% lower than those at regular stores.

It's foolish to throw away or let food go to waste," said Hansen, former Minister for Food and Environment." It's bad for the environment and obviously it is money spent on nothing. A supermarket like WeFood makes so much sense and is an important step in the battle to fight against food waste."

While Denmark alone is said to waste about 700,000 tons of food this year, the United Nations has stated that globally, food waste adds up to 1.3 billion tons. It is really shocking, considering that about795million people in the world are still short of food. Denmark, however, has taken measures. As a result, it wastes 25% less food than it did five years ago.

The We Food project is cooperation between the Food Bank and Dan Church Aid. Together they have collected over s 150,000 over the past years. They faced many problems while convincing the government to permit the sale of expired or damaged products. They were finally allowed to carry out the project,and the store is now specially run by volunteers. The money it earns is used to provide funds(基金)for Dan Church Aid's other projects in developing nations.

If We Food can successfully maintain its goods deliveries and remain popular in the long term,Dan Church Aid plans to open many other branches across Denmark.

【小题1】According to the second paragraph,the items sold at We Food are _____________.
A.second-handB.unique
C.popularD.perfect
【小题2】The We Food project is aimed at _____________.
A.helping the developing countries
B.turning all the rubbish into treasure
C.earning more money to expand the supermarket
D.attracting more people to buy their waste products
【小题3】What is the main problem We Food is faced with now?
A.Finding more volunteers to carry out the project.
B.Making sure they have plenty of items for sale.
C.Opening branches of We Food around the country.
D.Getting permission to sell expired or damaged products.
【小题4】Which of the following is the best title of the passage?
A.People stand in line outside We Food for food
B.We Food becomes the world-famous supermarket
C.Fighting against the problem of food waste in Denmark
D.The world's first expired or damaged product supermarket

Safety is a huge concern whenever I run with my earphones in. But I need music to run. Otherwise all I hear is the sound of my own breathing. So I’ve found a compromise: I run with only one earphone in. The music sounds off. It’s an imperfect solution.
An updated pair of headphones, called AfterShokz, aim to do better. AfterShokz bills itself as using bone conducting technology to conduct music from the front of the ear, delivering sound through your cheekbone and inner ear. This keeps your eardrum (鼓膜) free to hear everything else.
“Earbuds (耳塞式耳机) are typically designed to block out all sound, which is fine when you’re inside. But when you’re outside, you need all your senses. It would be like sending you out cycling with a blindfold on,” says Rod Annet, managing director of AfterShokz.
Here’s where AfterShokz comes in. The headphones hook over the back of your head with the main “bud” resting high up against your cheek. This keeps your ear free to delight in other sounds.
So do they work? In a word, yes. During a 45-minute jog, they didn’t bounce or shift. I heard far more of my environment than I normally do: a nearby bike there; a runner passing me again to my left; and so forth.
What about the downsides? If you’re a huge fan of high-quality sound, you might find the headphones a bit tinny. One friend expressed concerns about missing the ability to get lost in the music as you might be distracted by other noises, although I personally didn’t find that an issue.
Yet those are all minor details. For me, probably the biggest problem is the price. Ranging between £ 49.96 to £ 83.29, AfterShokz headphones aren’t exactly cheap.
With all that considered, would I recommend them? Yes. AfterShokz headphones are quite useful. While out jogging, they were light, painless, and easy to use. They made me feel safer.
【小题1】What is special about AfterShokz headphones?
A.They are a good choice for inside use.
B.They allow users to hear other sounds.
C.They can make music sound more beautiful.
D.They can deliver sound through your eardrum.
【小题2】What does the author’s friend think of AfterShokz headphones?
A.They prevent users getting lost.
B.They deliver high—quality sound.
C.They often move while users are running.
D.They fail to allow users to enjoy the music.
【小题3】The author thinks AfterShokz headphones .
A.are too expensiveB.seem quite useless
C.make users feel painD.are too complex to use
【小题4】What is the main purpose of the text?
A.To express worries.B.To introduce a product.
C.To share a personal story.D.To complain about a product.

   Since 1964,colleges and universities in the U. S. have used Test of English as a Foreign Language,or TOEFL,to measure an international applicant's(申请人的)level of English. Universities in English-speaking European countries began using the International English Language Testing System,or IELTS,in 1989. These two tests have been the main choices for English ability testing in higher education admissions for international students until now.

In recent years,several companies have developed new English language tests that are low-cost and easy to use. And they aim to do more than just offer greater choices in the admissions process.

Founded in 2012, Duolingo creates software that teaches users many different languages, including English. In 2014, the company launched its own test of English language ability.

Jennifer Dewar works with Duolingo, helping to develop the test. She formerly worked as an admissions official at Washington University in St. Louis, Misouri. The school is one of hundreds of colleges, universities and other organizations in and outside the U. S. that now accept the test results for international admissions into their study programs.

Dewar says Duolingo created the test to lower the barriers to higher education for people worldwide, especially those in developing countries.

TOEFL and the IELTS cost about $ 300. They are given in a limited number of centers around the world. Some test-takers have to travel to take the tests, adding to the costs. Duolingo offers its test entirely over the Internet for $ 49. All test-takers need is access to a computer with a microphone,listening device and self-facing camera.

TOEFL,the IELTS and Duolingo measure a person's English reading,listening,speaking and writing abilities. But it takes about 45 minutes to complete a Duolingo test,compared to three or four hours for TOEFL or the IELTS. It is possible because Duolingo uses artificial intelligence(人工智能)to adapt to test-takers' abilities,using fewer questions to measure their skills.

【小题1】Why were TOEFL and the IELTS set up?
A.To make people understand English-speaking countries.
B.To help teachers to teach in colleges and universities in Europe.
C.To test an international applicant's level of English.
D.To help international applicants to improve their sEnglish.
【小题2】When did Duolingo begin to use its own test of English language ability?
A.In 1964.B.In 1989.
C.In 2012.D.In 2014.
【小题3】Compared to TOEFL and the IELTS, Duolingo _____________.
A.widely used in English tests
B.a less difficult test
C.affordable and convenient
D.a face-to-face test
【小题4】What is the author's purpose in writing the text?
A.To introduce Duolingo.
B.To instruct us how to pass English tests.
C.To introduce overseas studying.
D.To promote English teaching.
