The world’s elderly population is increasing. The number of older people ---those age 60 years or older ---is expected to double by 2050 and is growing faster than all younger age groups across the globe. That comes with an increasing need for caregivers which can provide 24-hour care, not only at hospitals or nursing homes, but also at private homes.

Already, caregiving robots are programmed to ask questions a nurse would ask and can keep an eye on patients for falls. These robotic assistants are expected to become increasingly marketable and reach 450,000 by 2045 because of the expected caregiver shortage in the USA.

“Unluckily, the hard structure of present caregiving robots prevents them from a safe human-robot interaction(互动), limiting their assistance to only social interaction and not physical interaction,” said Ramses Martinez, an assistant professor in Purdue’s College of Engineering . “After all, would you leave babies or old people in the hands of a robot?”

Recent advances in material science have enabled the production of soft robots with deformable (可变形的) bodies or the ability to reshape when touched , but today the complex design prevents the use of this technology at home .

However, Martinez and other researchers have developed a new design method which shows promise in enabling the production of soft robots using a 3D printer.

“The soft machines move like humans. Their ability to change their body structure and movement to adapt ( 适应 ) to a wide variety of environments will improve caregiving greatly,” says Martinez .

The researchers are looking for partners to test and bring their technology to market.

1.What does the underlined word “That” in Paragraph 1 refer to?

A.The younger age group

B.The group of older people

C.The population across the globe

D.The growth of the elderly population

2.What is the disadvantage of the present caregiving robots?

A.They can’t provide safe physical interaction

B.They can’t communicate with patients

C.They can’t watch patients for falls

D.They can’t provide 24-hour care.

3.What do we know about Martinez’s new design method?

A.It requires a special kind of 3D printer.

B.It makes the production of soft robots simpler.

C.It has been put onto the market.

D.It is hard for users to master.

4.What is the text mainly about?

A.The robot industry in the future

B.Effects of population ageing

C.Robots for the elderly created with 3D printers

D.The development of caregiving robots

WeChat, the Chinese social media smartphone app, saw an increase in user numbers of 41 percent year on year to 500 million at the end of last year, in a sign that parent company Tencent is extending its reach for the mobile Internet. As one of the largest Internet integrated service providers in China and one of the most Internet users in China, Tencent’s profit grew 24 percent to RMB 20.98 billion per year, slightly higher than forecasts, driven mainly by online gaming profits. It is unclear how much WeChat contributed to Tencent’s profits but the app’s growth is a strong indicator of the company’s long-term health as it tries to adjust its business to be more suitable for mobile devices.

“We extended our leadership in games and online media, and made breakthroughs in emerging platforms such as online security and mobile payments.” Ma Huateng, Tencent chairman, said in a statement. WeChat is the second highest ranked social app in China, behind QQ, Tencent’s another chatting app, which claimed to have 815 million registered monthly users at the end of 2014.

Tencent has been unwilling to earn money through WeChat by flooding it with advertising, which could influence the users’ experience. But this is expected to change. Some analysts anticipated(预期) that advertising would be introduced on a large scale later this year. Early attempts to test ads on the service have not always gone smoothly. After a BMW ad was introduced on some users’ feedbacks in January, many users who were not targeted by the brand’s marketing complained of “discrimination” by Tencent’s data mining algorithm(数据挖掘算法). They claimed it unfairly treated them as not wealthy or successful enough to view the BMW ad.

1.What can we learn from the passage?

A. WeChat is ranked behind QQ in China.

B. Tencent wants to earn more through QQ.

C. WeChat contributed most to Tencent’s profits.

D. More advertising would not be introduced later this year.

2.How did some users feel when a BMW ad was introduced?

A. Uninterested. B. Untouched.

C. Unhappy. D. Unlucky.

3.What’s the best title of this passage?

A. WeChat, a Popular APP in China

B. WeChat, a Smartphone APP in China

C. WeChat, a Profitable APP of Tencent

D. WeChat, a Nonprofit APP of Tencent

There has been a large increase in the number of natural disasters over the past few years, and it is believed that global warming and climate change could cause even more disasters in thefuture. Some of the world’s leading cities are facing disasters like floods and heat waves.

London

London’s flood defences are getting older. Since 1982, the Thames Barrier(水闸)has protected the city from the threat (威胁)of flooding, but it was only designed to last until 2030 and close once every two or three years. About 31 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not solved

There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property(财产）in London’s flood risk area, so large scale flooding would be disastrous.

Paris

Over a six week period in July and August 2003, more than 1 1,400—mainly elderly people—died in France from dehydration(脱水)and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity(强度)are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?

One solution is to have air-conditioners installed（安装）in elderly care homes. But this is considered a short-term solution, as the increase in demand for electricity also increases carbon emissions(排放).

In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower,” which uses a covering of bamboo to act as a natural air-conditioner.

Shanghai

Shanghai is the fastest growing city on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.

About 250，000 people move to Shanghai every year in search of work, placing extra demands on energy consumption（消耗）. China depends heavily on coal—fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.

1.What problem should be settled now in London?

A. How to protect the city’s property

B. Where to build its flood defences

C. How to use the Thames Barrier to protect the city

D. How to improve the function of the old flood defences

2.Which of the following measures can’t solve the heat wave disaster in Paris?

A. Putting up new types of buildings with a covering of bamboo.

B. Having air-conditioners installed in elderly care homes.

C. Forbidding the city to build “Flower Tower”.

D. Encouraging architects to design new types of buildings.

3.The major threats to Shanghai are __________.

A. increasing population and coal-fired power stations

B. rising sea levels and typhoons

C. extremely high temperature and rising sea levels

D. extra demands on energy consumption and typhoons

4.The purpose of the passage is __________.

A. to tell us how to protect the big cities

B. to give advice on how to defend natural disasters

C. to explain what causes flood and heat waves

D. to warn us of the increasing natural disasters in big cities

阅读下面短文， 根据其内容写一篇60字左右的内容概要。

Over the past few years, there has been a big increase in the number of people sharing information online. In this article, we will learn about some positive reasons for people to share information online.

94% of those surveyed by The New York Times said they put a lot of thought into how the content they are sharing will be beneficial to others. We often share information with our friends in the office or at home to educate, entertain, or pleasantly surprise them. This is also true while sharing information online. If you look at the Facebook wall posts of your friends, you will realize that most of their updates are usually famous quotes(引述), entertaining videos, humorous images, funny jokes, etc.

A lot of people share information online to picture their true self to the outside world. Some people, especially those who are shy and not comfortable talking about their areas of interest in the presence of others, find it extremely convenient to share that information online with others.

According to the study, 78% of the people said they shared information online because it helps them develop better relationships. Today, people are so busy that they do not have the time to meet each other personally. A lot of people now “meet” each other online, rather than in places like restaurants and pubs.

Lastly, when we share our thoughts online, we are actively communicating with a large number of people who are a part of the World Wide Web. Sharing information will affect the viewpoint of others, or add to their understanding about the world.
