【题目】With the clicking of walking sticks and determined steps, a long line of walking group along the winding road is a fantastic sight. Almost each of the walkers is using some kind of fitness tracker. A few Fitbits, some Xiaomi wrist bands (手环), a couple of phone apps and some other pedometers (计步器) — and all, they say, are counting their steps.

Fitness trackers are in. Sales figures for 2016 released by Internet Data Center (IDC) indicated 25% market growth compared to the previous year, with Fitbit taking the lion’s share, followed by the brand Xiaomi.

However, the wearables market has had a rollercoaster ride in recent months. Jawbone, once a popular fitness tracker brand, announced that it is leaving the consumer market. Microsoft has removed its Fitness Band on its online store although it is still available on retail (零售) giant Amazon. Fitbit remains a key brand name at the heart of the fitness tracker revolution. But it is recently reported to be cutting down on workers, and its founder James Park said it experienced “softer than expected” sales recently.

Counting steps is probably the most common use of wearable devices (可穿戴设备), but recently experts have questioned whether the golden goal of walking 10,000 steps a day is actually worthwhile, and a US study concluded that health trackers did not aid weight loss.

Analyst Ben Wood from CCS Insight used to wear a fitness tracker on either wrist. Now, however, his concern is about users’experience --- these devices don’t tell you anything new after a while. There are also battery problems and many of the older and cheaper varieties aren’t waterproof (防水的).

1Which of the following can replace the underlined word “in” in Para. 2?

A. common B. wearable C. worthwhile D. popular

2What do we know about the fitness trackers from Para.3?

A. They still have many users. B. Their sales are decreasing.

C. They sell well on Amazon. D. Fitbit is leaving the market.

3How does the author sound about the future of fitness trackers in the last two paragraphs?

A. Pessimistic. B. Optimistic. C. Hopeful. D. Sympathetic.

【题目】The UN has recognized the contributions of volunteers on Dec. 5, International Volunteer Day. Here, the four things are offered to consider before taking the leap into overseas volunteering.

Choose your organization carefully

1 volunteering may be a fundraising mechanism(筹资机制) for a development project. For others, volunteering is fundamental to their programs, and those serving take on professional roles in longer-term development.

2

Volunteers want to help and make a difference, but most know this isn’t a purely selfless act. You will learn new skills, broaden your horizons and come to better understand yourself and the world. 3 Reflect on your motivations. You want to help reduce global poverty or protect the natural world, but what else? Have you always wanted to travel, but not as a tourist? Work with kids? When you understand your motivations, you’ll be in a better position to choose the option that is right for you.

Work alongside the local community

Often times, travelers volunteer in isolation(隔离) from the local community in which they are working in. 4 This enables you to ensure you are committing to a project that promotes long term and sustainable change.

A volunteer trip is just the beginning

5 Further ignite(点燃) the global change maker in you by taking your experience one step further when you return home. Spread the message of your transformative experience to others, helping to spark the change within them.

A. And that’s all OK.

B. Know why you’re going.

C. Don’t assume you know it all.

D. Communities always welcome volunteers.

E. Volunteer travel is a life-changing experience.

F. Some organizations require you to pay your own way, and often include a fee.

G. Make sure to travel with organizations that have strong partnerships with local communities.

【题目】For an increasing number of students at American universities, Old is suddenly in. The reason is obvious: the graying of America means jobs, coupled with the aging of the baby-boom generation, a longer life span means that the nation’s elderly population is bound to expand significantly over the next 50 years. By 2050, 25 percent of all Americans will be older than 65, up from 14 percent in 1995.The change poses profound questions for government and society, of course. But it also creates career opportunities in medicine and health professions and in law and business as well. “In addition to the doctors, we’re going to need more sociologists, biologists, urban planners and specialized lawyers,” says Professor Edward Schneider of the University of Southern California’s (USC) School of Gerontology(老年学).

Lawyers can specialize in “elder law”, which covers everything from trusts and estates to nursing-home abuse and age discrimination. Businessmen see huge opportunities in the elder market because the baby boomers, 74 million strong, are likely to be the wealthiest group of retirees in human history. “Any student who combines an expert knowledge in gerontology with, say, an MBA or law degree will have a license to print money,” one professor says.

Margarite Santos is a 21-year-old senior at USC. She began college as a biology major but found she was “really bored with bacteria.” So she took a class in gerontology and discovered that she liked it. She says, “I did volunteer work in retirement homes and it was very satisfying.”

1With the aging of America, lawyers can benefit ________.

A. from the adoption of the “elder law”

B. from presenting their professional services to the elderly

C. by enriching their professional knowledge

D. by winning the trust of the elderly to promote their own interests.

2Who can make big money in the new century according to the passage?

A. Retirees who are business-minded.

B. The volunteer workers in retirement homes.

C. college graduates with an MBA or law degree.

D. Professionals with a good knowledge of gerontology.

3Why can businessmen gain profit in the emerging elder market?

A. Retirees are more generous in spending money.

B. They can employ more gerontologists.

C. The elderly possess an enormous purchasing power.

D. There are more elderly people working than before.

【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
The cultures of the East and the West really distinguish each other a lot.
The origin of the eastern cultures is mainly from two countries: China and India. Both of the two cultures are developed by rivers—the Yellow River in China and the Hindu River in India.
When the two mother rivers gave birth to the Eastern culture, another famous culture was brought up on the Mesopotamian Plain-the Mesopotamian Civilization. This civilization later on developed into the cultures of Ancient Greece and Ancient Rome. Like the Chinese culture, the European culture also crossed waters. When the British settled down in America, their culture went with them over, the Atlantic Ocean. So the American culture doesn’t distinguish from the European culture a lot.
Take the language system for example. In the East, most languages belong to the pictographic language while the Western languages are mostly based on the Latin system. Other causes like human race difference counts as well. But what's more, due to the far distance and the steep areas between the East and West, the two cultures seldom communicate until recent centuries. So they grew up totally in their own ways with almost no-interference (干扰)from the other.
The differences are everywhere. But different cultures make the world of 21st century more colorful. The cultural gap should not be the obstacle to the civilization of human being. It ought to be the motivation of our going farther.

A. Let us work together to keep a variety of culture.
B. One important thing is to learn about other cultures.
C. And these two are well-known as the base of the European culture.
D. At the same time, some other differences add to the cultural differences.
E. This is because the culture systems are two separate systems on the whole.
F. They helped the two cultures develop for centuries and form their own styles.
G. They are obvious and affect people's ways of thinking and their views of the world.
