Most nations have at least one type of food that people from other countries think is unusual or unacceptable to eat. In France, people eat horse meat and frog legs. In South Korea and parts of China, restaurants serve dog meat. And in Australia, it’s common to cook kangaroo meat on the barbecue and use emu eggs to make pancakes.

The kangaroo and emu are native to Australia. Both animals are important to the national image of Australia and appear on the Australian coat of arms. They’re also central figures in the history of the native Australians. However, they still hunt these animals for their meat, fur and fat.

Today, Australian people continue to eat these animals. One of the reasons people eat kangaroo meat is that it’s high in protein and low in fat, so eating kangaroo is a good option for anyone on a diet. It’s also cheaper to eat kangaroo meat than other red meats. Because of this, a lot of university students choose to buy kangaroo meat. BBC News also reported that Australian scientists believe that eating kangaroo meat is good for the environment— kangaroos have different digestive systems than cows and sheep, meaning they produce less methane, the second biggest contributor to global warming.

While emu meat is high in iron and vitamin C, most people don’t think it tastes good. For this reason, they prefer emu eggs. One egg is large enough to make seven omelettes (煎蛋). And while ifs illegal to collect emu eggs from the wild, they can be bought from emu farms. Rather than cracking the beautiful dark shell, it’s better to dry it by putting a small hole at each end and blowing. Afterwards, you can even carve a design into the eggshell.

1.What is the purpose of the first paragraph?

A. To introduce the topic of the article.

B. To tell us the cultural differences of eating.

C. To suggest that different countries have different habits.

D. To indicate that people try to adapt to other countries’ diets.

2.According to the article, the kangaroo ________.

A. dies out due to hunting by Aboriginal tribes.

B. is full of large amounts of iron and vitamins in its meat.

C. is not considered healthy and environmentally friendly to eat.

D. is considered important in the history of the native Australians.

3.What is the main idea of paragraph 3?

A. Report the contributor to global warming.

B. Analyze the reasons why people eat kangaroo meat.

C. Tell people the fact that people like eating kangaroo.

D. Explain the benefits of eating kangaroo meat on the environment.

4.Which of the following statements is TRUE about emu eggs?

The United States estimates that about one out of every 10 people on the planet today is at least 60 years old. By 2050, it’s projected to be one out of 5. This means that not only will there be more old people, but there will be relatively fewer young people to support them.

Professor Richard Lee of the University of California at Berkeley says this aging of the world has a great effect on economics. “Population aging increases the concentration of population in the older ages and therefore it is costly,” he said.

Aging populations consume (消耗) more and produce less. With more people living longer, it could get expensive. But Mr. Lee says with continuing increases in worker productivity and smart planning, it can be manageable.

Societies have different methods for caring for the elderly, but each carries a cost. Generally, there are three types of support. Seniors can live off the wealth they gained when they were younger. They can rely on their family to take care of them, or they can rely on the government.

In industrialized nations, governments created publicly-funded (公共资助的) support systems. These worked relatively well until recent years, when aging population growth in places like the United States and Western Europe began to gradually weaken the systems finances. These nations now face some tough choices. Mr. Lee says the elderly in some of these countries must either receive less money, retire later or increase taxes to make the system continuable.

Most developing nations haven’t built this type of government-funded support, but have instead relied on families to care for their elderly. These nations also generally have a much younger population, which means their situation is not as urgent as more developed nations. But Mr. Lee says that doesn’t mean they can ignore the issue. “Third World countries should give very careful thought to this process, to population aging and how it may affect their economies — now, before population aging even becomes an issue,” he explained.

1.“Aging” in this text means .

A. there are more young people than old people

B. an increasing number of old people are dying

C. more and more young people are growing old

D. the percentage of old people in the world is increasing

2.What is Professor Richard Lee’s attitude towards population aging?

A. Indifferent.　　 B. Optimistic.

C. Negative.　　 　　 D. Worried.

3.The publicly-funded support systems in industrialized nations.

A. are facing the risk of failing

B. have failed to provide support for the old

C. will be replaced by other support systems

D. have greatly affected the nations’ economies

4.We can infer from the text that developing nations.

A. should prepare for population aging

B. don’t see population aging as an issue

C. are facing urgent situations of population aging

D. have better ways to deal with population aging

The problem of robocalls (自动语言电话） has gotten so bad that many people now refuse to pick up calls from numbers they don't know. By next year, half of the calls we receive will be scams(欺诈).We are finally waking up to the seriousness of the problem by supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, It’s too little, too late. By the time these "solutions" become widely available, scammers will have moved into cleverer means. In the near future, it's not just going to be number you see on your screen that will be in doubt. Soon you will also question whether the voice you're hearing is actually real.

That's because there are a number of powerful voice processing and automation technologies that are about to become widely available for anyone to use. At this year's I/O Conference, a company showed a new voice technology able to produce such a persuasive human-sounding voice that it was able to speak to a receptionist and book a reservation without being found.

These developments are likely to make our current problems with robocalls much worse. The reason why robocalls are a headache has less to do with amount than accurateness. A decade of data violation of personal information has led to a solution where scammers can easily learn your mother's name, and far more. Armed with this knowledge, they're able to carry out individually targeted campaigns to cheat people. This means, for example, that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller's, tricking you into "confirming" your address, mother's name, and card number. Scammers follow money, so companies will be the worst hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice processing technologies may weaken that gradually.

We need to deal with the insecure nature of our telecom networks. Phone consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by, or abandoning phone calls altogether and moving towards data-based communications-using apps like FaceTime or WhatsApp, which can be lied to your identity.

Reliability is hard to earn but easy to lose, and the problem is only going harder from now on.

1.How does the author feel about the solutions to the problem of robocalls?

A.Panicked.

B.Confused.

C.Embarrassed.

D.Disappointed.

2.Taking advantage of the new technologies, scammers can____________?

A.aim at victims accurately

B.damage databases easily

C.start campaigns rapidly

D.spread information widely

3.What does the passage want to say______________?

A.Honesty is the best quality.

B.Technologies can be double-edged.

C.There are more solutions than problems.

D.Reliability holds the key to development.

4.Which of the following would be the best title for the passage?

A.Where the Problem of Robocalls Is Rooted

B.Who is to Blame for the Problem of Robocalls

C.Why Robocalls Are About to Get More Dangerous

D.How Robocalls Are Affecting the World of Technology

British people work some of the longest hours in Europe, but are among the least productive. Now some companies are shortening the working week to increase efficiency, health and happiness.

Rich Leigh has introduced a four-day week at his PR company. In fact, his entire company has Friday off, because his firm has adopted a four-day week. It is one of several UK businesses that now operate like this: staff still get paid their previous five-day salary, but they work a day less. The company found that they achieved just as much-and there were even signs of growth. “The key to the scheme’s success,” Leigh says, “is how happy our employees now are.”

The average British worker takes only a 34 minute lunch break and works 10 hours overtime each week (more often than not this is unpaid). Yet UK productivity falls seriously behind their European neighbors, who tend to work fewer hours.

British working practices have caused loss and damage to the nation’s health and happiness. More than half a million workers in the UK were signed off with work-related stress or anxiety last year. Moreover, the work landscape itself is changing. Automation and AI will have a significant impact on the labor market, where unsteady work becomes more common.

Britain is the only EU member that allows workers to ignore the EU working time limit and work longer hours. For campaigners, now is the time for a change. O’Grady, an advocate, argues that where businesses have increased their profits (利润)as a result of automation, success should be shared with workers in the form of reduced hours. “It’s time to share the benefits from new technology, not allowing those at the top to grab them for themselves.” she says.

1.We can learn from the passage that ________.

A.British people are the least productive in the world

B.Most companies in Britain have conducted a four-day week

C.PR company has witnessed a rise in employees’ happiness

D.British people work longer and get more payment than other countries

2.Which is the proper description of British working practices?

A.The working time of British workers is within the EU limit.

B.In productivity, Britain is beaten by the United States.

C.Profits gained from new technology are on the decrease.

D.Automation and AI are likely to cause an unsteady work market.

3.Which can be inferred from O’Grady’ s words in the last paragraph?

A.It’s time for employers to share the increased profits created by automation.

B.Workers should benefit from automation in the form of less working hours.

C.New technology should belong to both businesses and workers.

D.Businesses can’t make more profits without new technology.

4.What is the author’s purpose of writing the passage?

A.To introduce some British firms’ switch to a four-day working week.

B.To explain the reasons why British workers suffer stress and anxiety.

C.To appeal for more reasonable working conditions.

D.To show the present productivity problem in Britain.

Many people believe that all ice cubes are created equal, but they are not. At least that’s what the folks at California’s Glace Luxury Ice Company would like us to believe. The Davisbased company says that the ice cubes they make are healthier and last longer than the ones that we throw into our drinks on a daily basis. What’s more, the company also says that their ice cubes do mot leave behind an aftertaste(余味)in drinks, like regular ones do.

In order to create these unique ice cubes, Glace Luxury begins with water that has been rid of the hazardous impurities(杂质)that the company says can lead to cancer and exist in regular ice. They then freeze it in large blocks. Once ready, the ice is carved into perfect cubes and each cube measures 2.5 inches across. Besides being healthier, these ice cubes apparently also take longer to melt. The company says that each ice cube can last up to 30 minutes.

Of course, those ice cubes do not come cheap. Those that wish to have a taste of this “tasteless” frozen perfection will have to pay $325USD for a bag of 50 ice cubes. That comes to $6.50USD for a single cube of ice!

The unique product is the brainchild of Robert Sequeira, a former business school lecturer who said that he wanted to establish a profitable business that could be easily scaled. Given that he can make as mush Glace Luxury ice as he needs for as little as $0.12USD per cube, he thinks that the idea certainly meets the standard. Now, if he can find that the few people can afford to buy this Glace Luxury ice, life would be great!

1.People at California’s Glace Luxury Ice Company probably want consumers to believe that _____.

A. ice cubes are healthy for people to use

B. their ice cubes add tastes to drinks

C. all ice cubes are created the same

D. their ice cubes are different

2.What does the underlined word “hazardous” in paragraph 2 mean?

3.Compared with regular ice cubes, the ice cubes created by Glace Luxury Ice Company_____.

A. taste much bette

B. look much more beautiful

C. have more different shapes

D. are healthier and melt more slowly

4.What does the author think of the ice cubes created by Glace Luxury Ice Company?

A. They will be a big success
