As is known to us all is that mobile phones make it easily for us to communicate. Therefore, in the meantime, they also lead to a great many of problems.

To shoot a scene of people eating food, you need two different perspectives (角度). To record a bus journey to school, you need three quick cuts. To complete this short, morning rush-hour video blog – or “vlog” – you need four pieces of music. 1.
With more than 90 million vlogs available online, and 2,000 posted every hour on the YouTube video-sharing site, CBS News says they are mainstream with people born after 1995.
2. More young Chinese people have become inspired to grab a camera and recount the details of their day on Sina Weibo, Bilibili or WeChat Moments.
“The most important thing about vlogging is to tell a good story. Other visual effects are auxiliary (辅助的),” wrote US vlogger Casey Neista, who has almost 10 million subscribers on YouTube.
Chinese vlogger Wang Xiaoguang is an example of a good storyteller. In one of his popular vlog posts, Wang tells the story of traveling to Japan. While there, he took a ride in the wrong direction and got lost. Worse, he forgot to bring a phone charger. 3.
Another key aspect of vlogs is that the content is based on everyday life, according to Ouyang Nana, 18, a young Chinese musician. She documents her life at Berklee College of Music. Ordinary as vlogs are, as many as 15 million fans share her wows and woes (喜怒哀乐) on a daily basis.
4. Peng Yixuan, a news reporter with China Daily, recorded her first experience attending and reporting on the two sessions in March of this year. With a relaxed, chatty and personal approach, she presented the conferences, “bringing more warmth” to the grand political event, according to People’s Daily.
There are popular vlogs for beauty, gaming, fashion, food and travel. Vloggers are learning new ways to experience the thrill of them. 5. Then what are you waiting for? Grab a camera!
A.They come from all walks of life.
B.However, he didn’t take the number of his hotel.
C.Vlogging has taken China by storm over the past year.
D.Some other popular vloggers choose to show their careers.
E.Vlogs pave the way for future advertising and sales campaigns.
F.Luckily he was able to borrow money from a stranger and escape trouble.
G.Vloggers have these techniques in mind as they film their daily activities.
Throughout history, music spread among people of different cultures. In today’s technological advanced society, however, people spread music online, sometimes without an artist’s permission. This can lead to many problems, and music companies are now cracking down on this practice. Sharing music online without permission is theft.
Sharing music online prevents recording companies from making money from their efforts. They say that sharing music online has resulted in a huge drop in profits and sales over the past 10 years. People who find music for free online are not paying for CDs or every MP3 downloaded. To truly understand the influence of music piracy (盗版行为) on creators, one must understand how many people are involved in the recording process. For the sale of each album, profits must be shared between musicians, sound engineers, music producers, managers, advertisers, and the company selling the product. Many people believe sharing music only affects the recording artist, but the reality is that sharing hurts business for all companies involved.
There are many people who don’t see the harm in sharing music online and even think they have the right to do it. One online blogger states that he originally paid for an entire CD and that he should be able to do with the material whatever he wants. While he may have legally paid for the music, he does not have the right to provide permission, which means people like the blogger are thieves.
Although we don’t spread today’s music the same way we did before, there’s no doubt that people around the world love to share music. However, internet piracy would prevent musicians from continuing producing albums for fear of theft. Therefore, if people want to continue listening to their favorite artists, they need to buy their music so that artists will make enough profit to continue their music careers.

D.Introduction—Supporting statements—Conclusion.
4.What is the main idea of the text?

C.Downloading music should be punished. D.Music piracy is good for music lovers.
Mice and rats have long been used in medical research because of their biological similarities to humans. Now, scientists have trained rats to drive small vehicles created for them. One of the main findings of the experiment was that the driving activity seemed to help the rats relax.
Researchers at the University of Richmond in Virginia led the experiment. The team built tiny cars out of plastic and other materials. The vehicles had an opening at one end where electrical wires were attached. By touching one of three different wires, the rat could control the direction of the vehicle.
Researchers trained 17 rats over several months to drive around the experiment containers. The animals proved that they could be trained to drive forward as well as in other directions to get to the sweet treats placed inside the containers.
The researchers examined levels of two hormones (荷尔蒙) in the rats—one that causes stress and another that reduces it. All rats that took part in the training had higher levels of the hormone that reduces stress. The research suggests the increased relaxation levels could be linked to the enjoyment of successfully completing a new skill. The team also found that the rats that drove themselves showed higher levels of the stress-fighting hormone than those that simply rode in small cars controlled by humans.
Lambert said the most exciting result of the experiment for her was about the possible effect on humans. The research may open new areas of non-drug treatments for people suffering from mental health conditions.
“There’s no cure for schizophrenia or depression and we need to catch up,” she said. “And I think we need to look at different animal models and different types of tasks and really respect that behavior can change our neurochemistry (神经化学). ”
Speaking to the British-based magazine New Scientist, Lambert said her team is planning to continue experiments to learn more about how the rats learned to drive. The new research will also examine why some activities appear to reduce stress, and which areas of the brain are involved in the process.
1.What did the experiment find?
A.Rats are able to drive vehicles. B.Rats feel relaxed when driving.
C.Rats can be used in medical research. D.Rats are biologically similar to humans.
2.The finding of the hormone examination in the rats suggests that ___________.
A.one hormone causes stress and another reduces it B.acquiring a new skill brings about joy
C.levels of hormone are controlled by stress D.relaxation contributes to enjoyment
3.The research is significant because ___________.
A.it may lead to a way to treat human mental problems
B.it will affect the way that humans drive their cars
C.it may help people train animals better.
D.it can surely change neurochemistry
4.What Lambert’s team will do next is find out ___________.
A.which parts of the rats’ brain control their emotions
B.why rats have the ability of fighting stress
C.when activities affect the levels of stress
D.why certain activities reduce stress
