When you think of the future,you imagine having some sort of robot friend in your life.Musio,a new robot unveiled recently,is something like that.

Musio is an artificial intelligence software that runs on Google's Android mobile OS,and is packaged in the form of a round little robot with pointy ears.It doesn't move around,but it has a digital screen for its eyes and heart that are used to express the robot's emotions.It also comes with a remote pointer device,called Sophy,which is used to detect objects that trigger different interactions with Musio.

The robot was created by AKA,a company specializing in machine learning and natural language processing.It's designed to interact with its users with a voice interface,much like you'd use Siri.But Musio's creators,Wilmington, Delaware-based AKA Study,stress that this is a much different experience than using Siri—Musio can have interactive conversations and remember information about its users,sort of like a little person.Musio can do all sorts of things like controlling home automation and it has a number of integrated sensors.The robot is also programmable and it is able to speak naturally.It is designed to share its emotions via faces on its LCD screen.There are three versions of Musio that vary on hardware.The Simple version has a 1.2GHz dual core processor,1800 mAh battery, 16GB storage and isn't internet connected.It can only recall the last five conversations it has.

Beyond running on the open source Android platform,Musio is also Arduino compatible.The Arduino platform is an open source electronics platform built to be easy to program.Its purpose is to take different inputs through a suite of sensors and then relay commands to lights,motors,or actuators as a result.Musio is also compatible with the Zigbee wireless standard used by a range of smart home devices,so it's possible that developers could intertwine the robot with other appliances and turn it into a sort of voice-activated smart home hub with a personality.

And there are several educational accessories that come with Musio,such as flash cards and a fold-out accordion board book.Using Sophy,the pointer,Musio can interact with these objects thanks to a Bluetooth low-energy connection and a special code implanted in the printed materials.

1.What is Musio?

A. A digital e-book reader.　　 B. A language learning software.

C. An artificial intelligence robot.　　 D. A voice-controlled website.

2.How is Musio different from Siri?

A. It can hear and understand what its user speaks.

B. It connects a lot of programs.

C. It will give a variety of commands.

D. It can exchange verbal information with its users interactively.

3.Why could developers intertwine Musio with other appliances?

A. Because it could run on the open source Android platform.

B. Because it has a strong compatibility.

C. Because it takes different inputs through a suite of sensors.

D. Because it relays commands to lights,motors,or actuators.

4.What does the underlined word “accessories” in Paragraph 5 mean?

A. Attachments.　　 B. Sensors.

C. Pointers.　　 D. Platforms.

We all know that eating junk food can make us fat. However, a new study suggests that it can do more than that – it can also make us lazy, reported CBS News.

In the study, researchers at the University of California, Los Angeles, US divided 32 female rats into two groups. The first group was fed a diet of healthy food such as corn and fish, while the second was given a diet of highly processed (加工的) food rich in sugar, namely “junk food”.

Within three months, the rats in the second group were already much fatter than those on the healthy diet. And when researchers trained the rats to do simple tasks, they found even more differences between the two groups rather than weight.

During the task – pushing a lever (杠杆) to receive a reward of sugar water – the rats on the junk food diet were found to be less willing to move, and they took longer breaks between each push than the lean rats did.

“It is as if the rat is thinking ‘This is too much work’,” Aaron Blaisdell, leader of the study, told the Los Angeles Times.

But what about the possibility that the fat rats were less passionate about getting sugar water because they were already eating lots of sugar in their daily diet? That’s why researchers repeated the tests by rewarding fat rats with plain water when they were extremely thirsty. However, the results came out just the same.

According to researchers, these differences suggest that junk food changed the chemistry in the rats’ brains.

The experiment didn’t end there. After six months, the rats’ diets were switched, and the overweight rats were given a healthy diet for nine days. However, this change didn’t help reduce their weight or improve their ability to perform tasks, which means the effects of their junk food diet persisted (持续存在). “There’s no quick fix,” said Blaisdell.

For a long time, we’ve believed that people become fat because they are lazy. But this study has proven the opposite to be true as well, which indicates that laziness and obesity are a “vicious cycle (恶性循环)”.

So, if you constantly feel tired, lacking any urge to get up from your chair, it could be that you’ve been studying too hard. But you should also pay attention to your diet.

1.During the first three months of the experiment by researchers at the University of California, ______.

A. rats from the healthy diet group ate nothing but corn and fish

B. rats on the junk food diet ate more than those on healthy diet

C. rats on the healthy food diet performed better at simple tasks than those on the junk food diet

D. rats on the junk food diet seemed uninterested in sugary food

2.The researchers rewarded thirsty rats with plain water in the lever test to ______.

A. help them control their weight

B. test whether fat rats lost interest in the test because they had taken enough sugar

C. change the diet habits of fat rats

D. find out the influence of sugar on rats’ brains

3. The underlined word “there” refers to ______.

A. after the rats on the junk food diet had worked hard to get sugar water

B. after the type of food rats prefer had been identified

C. after a quick cure for obesity had been found

D. after the fact that fatter rats are lazier than lean rats had been found

4.We can conclude from the article that ______.

A. fat people are usually lazier than lean people

B. people should switch between different types of diets to keep healthy

C. being overweight and being lazy can feed into each other

D. laziness is the main cause of weight problems

5.Which of the following is Not Right according to the passage?

A. Eating junk food can make us fat.

B. Researchers got different results after repeated the tests to fat rats.

C. For a long time, we’ve believed that people become fat because they are lazy.

D. If you constantly feel tired or study too hard, you need to pay attention to your diet.

Have you got some paper, a pair of scissors and, above all, a desire to decorate your house? Then, we have the perfect holiday artwork for you: Make Star Wars snowflakes (雪花). Remembered as a cherished form of work in classrooms before the holidays, paper snowflakes have drawn many people's attention again.

The designer, Anthony Herrera, just recently released his 2013 collection. "The Star Wars snowflake designs began as just doing designs of characters that I and my daughter wanted to make three years ago," Herrera told us in an email. "The second year I introduced vehicles, and this year I decided to push further by designing battle scenes."

Sometimes, he feels a bit bored with his job. With each year, the designs have got more detailed and various, but the process of creating them remained the same: sketching (画) figures on paper with a pencil until a symmetrical (对称）pattern comes out, then scanning the designs and cut them with scissors. However, he says he has plenty of ideas for new flakes next year, so no two will ever be the same. Hopefully with Star Wars: Episode VII coming in 2015 he'll have even more work in the future.

Check out your favorite finished versions of Herrera’s flakes (from both 2013 and previous years) and download the pictures beneath them and then get down to creating your own work. A warning: Most designs aren't for the casual flake-maker, so patience you must have.

1.From the text, we know that Herrera ______.

A. can make snowflakes with his daughter's help

B. made more complicated designs before 2013

C. introduced paper vehicles in 2011

D. will make a great variety of detailed paper flakes

2.Herrera is fed up with the job sometimes because ______

A. he has to design detailed and different patterns

B. he has to follow the fixed process of paper cutting

C. he spends much time designing, scanning and cutting

D. he has few ideas for what the next designs will be like

3.By writing the last paragraph, the author tries to ______.

A. offer us more information about Herrera’s paper cutting

B. tell us how to download picture of snowflakes

C. instruct people to be a real creative artist

D. remind us of being patient with Herrera’s designs

The porter brings your bags to your room and helpfully explains all you want to know. Then he points to the phone and says, “If there's anything else you need, just call.” All this time you have been thinking one thing, “How much should I tip(付小费) him?” To make your next trip a little easier, here's a guide to tipping across some Asian countries.

Bangkok

In general, the more Westernized the place is, the more likely you will be expected to leave a tip. Some top-end restaurants will add a 10% service charge to the bill. If not, waiters will appreciate you tacking on(附加) the 10% yourself. However, if you're eating at a lower-end(低档的) restaurant a tip is not necessary. If you're staying at one of Bangkok's many five-star hotels, expect to tip the porter 20 to 50 baht(泰国货币单位), depending on how many bags you have. Taxis are now metered in Bangkok. Local custom is to round the fare(车费) up to the nearest five baht.

Hong Kong

Tipping is customary in this money-mad metropolis(大都市). Most restaurants add a 10% service charge to the bill, but the extra money often ends up in the pocket of the owner. If the service is good, add another 10% to the bill, up to HK $100 in an especially nice restaurant. For HK $10 hotel porters should do it at all but the nicest hotels where a new HK $20 bill may be more acceptable. When in a taxi, round up(凑整数) to the nearest dollar.

Kuala Lumpur

Tipping in Malaysia is limited to the expensive Westernized hotels, which often add a 10% service charge to your meal or hotel room. If you are at a hotel restaurant, expect a 10% service charge. But at local restaurants, there's no need to add a tip. At five-star hotels, one or two ringgit(马来西亚货币单位) will content a porter. At lower-end buildings don't feel you have to tip. Like Bangkok, many taxis are now metered so you can just round up to the nearest ringgit.

Seoul

Tipping is not part of Korean culture, although it has become a matter of course in international hotels where a 10% service charge is often added. If you're at a Korean barbecue joint(烧烤处), there's no need to add anything extra. But a nice Italian restaurant may require a 10% contribution. If you're at a top-end hotel, so expect to pay 500～1 000 won per bag. Taxi drivers don't accept a tip. Keep the change for yourself.

1.In which of the following cities is it unnecessary to tip the taxi-drivers?

A．Bangkok.          B．Hong Kong.        C．Seoul..            D．Kuala Lumpur

2.Which of the following is NOT the unit of money?

A．Baht             B．Charge.           C．Won.             D．Ringgit.

3.From the text, we can infer tipping comes from _______.

A．the west          B．Hong Kong         C．Asian countries     D．Bangkok

4.If you stay at a five-star hotel in Kuala Lumpur, how much will you pay the porter at least?

A．one ringgit.        B．10% of service charge                    C．half a ringgit.    D．two ringgit.

5.The writer seems _______.

A．to give the readers some advice on how to tip B．to tell the readers how to travel

C．to ask the readers to go on a travel to Asian cities   D．to make the trip more pleasant
