（二）阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。
Roby Mini is just 40 centimeters tall, has a large round screen for a head and has been designed to help senior citizens living alone.
Manufactured by robotics company Shanghai PT Info, the brightly colored robot, which costs 5,000 yuan ($790), was launched on Aug 14 to help entertain and monitor elderly people.
In Shanghai last year, the number of registered residents at least 60 years old was 4 million. That was nearly 30 percent of the population. By 2018, the figure is projected to rise to 5 million.
With many living alone, robots such as Roby Mini can help play a crucial role in caring for the elderly. "It will change the way people interact with digital products," Hong says.
Founded in May, Shanghai PT Info had already done the groundwork. In fact, the research team spent three years developing the speech recognition system before the firm was officially launched.
With 360-degree wheels hidden under its body, Roby Mini can follow a person through face recognition and strike up a conversation, tell jokes or provide information.
The robot also works as a computer terminal, supplying weather information, ordering groceries online and even booking taxis. Roby Mini can be connected to other gadgets as well, such as smart wristbands or magnetic devices on doors.
Roby Mini can also connect an elderly owner to a doctor through its high-definition screen.Already Shanghai PT Info is talking to three community hospitals in Shanghai's Minhang district. Since the robot is linked to the Internet, it can support long-distance audio and video calls.
Mass production started this month and Shanghai PT Info plans to manufacture 200,000 units this year.
But the future is not easy for Shanghai PT Info. Earlier this year, Flyingwings Intelligent Robot Technology (Shanghai) introduced a machine with sensors that will ring an alarm when an elderly person falls down.Tianjin ShangjiuShengyuan Technology Group also
developed a robot for seniors in 2014. Owners can turn on the lights and air-conditioning units by pressing buttons on the machine.It can also remind elderly owners to take pills, and inform them of hospital checkups and family birthdays.
1. Roby Mini is the name of.
A. a robotics company
B. a robot
C. a senior citizen living alone
2. Roby Mini is designed to.
A. help look after children living alone in senior high school
B. help entertain and monitor senior citizens
C. change the way people interact with digital products
3. According to this passage, the number of registered residents at least 60 years old will
be.
A. 4 million next year
B. 30 percent of the population
C. increase to 5 million by 2018
4. The writer thinks “the future is not easy for Shanghai PT Info” because.回答
A.there are too many elder people in Shanghai
B. Roby Mini cannot ring an alarm when an elderly person falls down.
C. the company will face tough competition in the marketplace
5. The best title for this passage is.
A. How to Use a Robot
B. Elder People Increase in Shanghai
C. Robot Gives Help to Older People
（三）阅读下面的短文，根据文章内容从A、B、C三个选项中选出一个最佳选项。
If you want your product description appealing and informative, write your article linking features and benefits first. It's often not enough to just list the features of a product as your
audience may not always understand them. Use
language to convey how any one feature will benefit the buyer and 回答
purchasing the item will make the consumer's life easier. Potential buyers want to know what the product will do for them.Second, use clear and decisive language. It's important when writing product descriptions to be concise. Use common language and terms that
are easy to
. Clearly describe the product without
too technical or boring so the reader stays engaged. Last but not the least, include a
call-to-action. The best product descriptions always
a sale. Be creative and encourage the potential buyer to purchase your product by telling them exactly how to do it.

But the architects remain optimistic. The first few printed blocks are meant to be test pieces as they improve the process. It takes about a week to print a 3-meter high block right now. The project's leaders hope to eventually get that down to two hours and finish the first of 12 rooms in a year, and the entire house in less than 3 years. Ultimately, 3D Print Canal House is an architectural research project, one that is very much being conducted in the public eye: you can actually buy tickets to visit the construction site for 2.50 Euros. The top floors will become more ornate, for example, as newer techniques are incorporated. They'll explore the possibilities of 3D printing, like the honeycomb walls or an entire room recycled, redesigned, and built anew. Nobody's going to move into a 3D printed house soon, but, if anyone ever does, something might be learned from this experiment by the canal. 1. According to the passage, the 3D printer can type with plastic evenly. 2. This 3D printer printed some blocks to test its work. 3. The project's leaders will finish the entire house in less than 3 years. 4. 3D Print Canal House is printed to live. 5. The canal house will be decorated more. 解析： 1. F

? ? ? It is amazing to note that the Internet is still such a new device，and yet it is one of the fastest and most powerful media tools. But think about it for a moment. On the Internet，a big online company can be run by only two guys in their garage. So it is only reasonable then，that people shopping online would be a little?leery?of the security levels. ? ? ? Internet giants such as Microsoft knew consumer confidence was the key to getting virtual(虚拟的) shopping off the ground，and they work hard to make people feel safe to shop online. ? ? ? Credit card companies，too，quickly saw the potential for online shopping，and have installed things like online shopping insurance for people. If you ever have a problem with your online credit purchases，many credit card companies will happily refund(退还) your money and then set their claws on the company that wronged you. Now that's buying power! ? ? ? There are other bonuses for online shoppers，of course. No lineups，for one. No annoying mall shopping carts with broken wheels and kids crying because their parents won't get them what they want. ? ? ? When shopping online，consumers can sit down，have a coffee，and wear their slippers，not having to worry about their hair or parking，and just clicking through sale after sale. Comparison shopping couldn't be any easier. And thanks to courier companies(快递公司) getting in on the act，you never need to wait longer than a day or two to get those all important purchases delivered right to your door. ? ? ? No wonder so many companies are shaking their heads at traditional retailing?and instead looking to the?“virtual”world to attract online shoppers. 1．The underlined word “leery”in the first paragraph?means being very sure. ? 2．Consumer confidence in online shopping mainly relies on?security in shopping. ? 3．Internet giants, traditional retailers, courier companies and credit card companies?have made contributions to the popularity of online shopping. 4．The author think of the current online shopping?as safe, convenient and fast. 5. Nowadays many companies are trying to cooperate with the online shoppers instead of traditional retailers. ? 答案：F T F T T 二、阅读理解：阅读下面的短文，根据文章内容从A、B、C、D三个选项中选出一个最佳选项。 ? ? ? While there are still many people who don't feel comfortable using a credit card to buy over the Internet, e-commerce is absolutely here to?stay. If you take a few precautions buying over the Internet can actually be safer than using your credit card in a restaurant. ? ? ?Just as you should notice your surroundings and suspicious-looking people when withdrawing (提取) money from an ATM, you should know how to recognize the warning signs of Internet tricks and take steps to avoid being a victim when shopping online. Here are some good tips to remember when shopping online: ? ? ? Before submitting your personal information to a site, try to find out how the information may be used and whether it will be sold to or shared with other businesses. If you don't like what you read, shop somewhere else.
