【题目】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.

【题目】"Indeed," George Washington wrote in his diary in 1785, " some kind of fly, or bug, had begun to eat the leaves before I left home. " But the father of America was not the father of bug. When Washington wrote that, Englishmen had been referring to insects as bugs for more than a century,and Americans had already created lightning-bug(萤火虫).But the English were soon to stop using the bugs in their language, leaving it to the Americans to call a bug a bug in the nineteenth and twentieth centuries.

The American bug could also be a person, referring to someone who was crazy about a particular activity. Although fan became the usual term, sports fans used to be called racing bugs, baseball bugs, and the like.

Or the bug could be a small machine or object, for example, a bug-shaped car. The bug could also be a burglar alarm, from which comes the expression to bug,that is,"to install(安装)an alarm". Now it means a small piece of equipment that people use for listening secretly to others' conversations. Since the 1840s,to bug has long meant" to cheat" , and since the 1940s it has been annoying.

We also know the bug as a flaw in a computer program or other design. That meaning dates back to the time of Thomas Edison. In 1878 he explained bugs as"little problems and difficulties" that required months of study and labor to overcome in developing a successful product. In 1889 it was recorded that Edison" had been up the two previous nights discovering' a bug' in his invented record player."

【题目】China is a land of bicycles.At least it was back in 1992 when I traveled the country.Back then everyone seemed to be riding a bicycle.Millions of them,all black.Cars were rare.Yet since my arrival in Beijing last year, I’ve found the opposite is true.There are millions of cars.However, people still use their bicycles to get around.For many, it's the easiest and cheapest way to travel today.Bicycles also come in different colors—silver, green, red, blue,yellow, whatever you want.

It’s fun people biking.They rush quickly through crossroads, move skillfully through traffic,and ride even on sidewalks.Bicycles allow people the freedom to move about that cars just can’t provide.

Eager to be part of this aspect of Chinese culture,I decided to buy a bicycle.Great weather accompanied my great buy.I immediately jumped up on my bicycle seat and started home.

My first ride home was orderly.To be safe, I stayed with a“pack”of bikers while cars on the streets came running swiftly out of nowhere at times.I didn't want to get hit.So I took the ride carefully.

Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States.The streets here were wide,so crossing took time,skill and a little bit of luck.

I finally made it home.The feeling on the bicycle was amazing. The air hitting my face and going through my hair was wonderful.I was sitting on top of the world as I passed by places and people.Biking made me feel alive.

【题目】Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new “species” of human has kept rising, they have been given a new name — phubbers(低头族).

Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

Although the ending sounds overstated the damage phubbing can bring is real.

Your health is the first to bear the effect and result of it. “Constantly bending your head to check your cell phone could damage your neck,” Guangming Daily quoted doctors as saying. “the neck is like a rope that breaks after long-term stretching.” Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

But that’s not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

1For what purpose does the author give the example of a cartoon in Paragragh2?

C. Results of phubbing. D. Measures to reduce the risks of phubbing.

【题目】Britons may like to complain a lot, but they rarely do so right now, explains BBC writer Ruth Margolis. They would rather grumble (发牢骚) afterward. This is because Britons hate to put someone out and cause any embarrassment. Margolis writes, “For instance, I’m much more comfortable just leaving that piece of raw chicken on my plate instead of complaining to restaurant staff. But beware: if this kind of thing happens when you’re dining with an American, they will most likely speak up on your behalf and not understand why you find this ashamed.”

In a BBC blog post comparing cultural differences between the UK and the US, Margolis mentions a few other things that Americans like to do that are offensive to Britons.

Not making introductions

Margolis says most Britons dislike this approach because “talking to strangers without being introduced gives them a stomachache”. Americans rarely introduce a new friend to their friends at parties. Strangers are supposed to introduce themselves.

“Quite” good

Using “quite” to mean “very” happens a lot in the US. But if you are invited to a dinner party in Britain, don't describe the meal as “quite good” if you want to express high praise. To Britons’ ears, “quite” detracts from the “good”: the meal was OK but could have been better.

Money Talk

Americans can talk about money subjects for hours without feeling uncomfortable. For Britons, says Margolis, “Talking about how much we make is unthinkable even 1ess so than discussing our feelings.”

Over-politeness

“It’s not that I want shop assistants to be actively rude. But neither do I want to expend energy responding to someone who's been paid to ask: ‘How are you today?’” says Margolis. In the US, it is not unusual to be greeted by a perfect stranger as “honey” or “sweetie”. But Margolis says Britons find put-on friendliness, especially in stores, deeply irritating.

【1Margolis’ dining experience in Paragraph 1 shows that_______.

A. Britons are particular about foods

B. Britons are not good at complaining

C. Americans usually complain directly

D. Americans complain more than Britons

【2】Which of the following might Margolis agree with?

A. Britons enjoy talking about their feelings.

B. Americans introduce themselves at parties.

C. Americans dislike talking to strangers at parties.

D. Britons feel happy if treated like close friends.

【3】The underlined phrase “detracts from” in the text probably means ____.

A. differs greatly from B. increases the quality of

C. reduces the strength of D. draws attention away from

【4What does the text mainly talk about?

A. How to get on well with westerners.

B. How to start conversations with Britons.

C. Ruth Margolis’ tips on public behavior.

D. Some American habits that annoy Britons.
