You’re lost in the world of dreams and sleep. You roll over, smiling as you come across a swimming pool filled with chocolate. And then, your wonderful dream becomes a nightmare when someone is screaming, “Get up!” It’s just what every teenager goes through each morning!
Now, there seems to be one school that finally understands that requiring teens to show up at 9 am is not just cruel but also harmful to both the kids and the school.
The Monkseaton High School in North Tyneside, Britain, recently decided to experiment to see if there is any difference in student behavior if they just pushed back the start of their day by one hour, from 9 am to 10 am. And the results are surprising.
Since carrying out the later start, Monkseaton has seen a 28% drop in truancy, even hardly any lateness, and best of all, higher test scores. One of the reasons is that the teenagers are much happier to have the extra hour of sleep, but there is also a scientific reason behind why they need the extra sleep.
The school’s decision to push back the time was based on the research done by Oxford Professor Russell Foster, who pointed out that teenagers and adults have different sleep cycles, explaining why teenagers go to bed late and wake up late.
While adults are wide awake and ready at 8 am, teenagers are not fully awake until 10 am, sometimes even noon. Teachers may argue that their students perform better in the morning, but in fact, it is because they are in the zone while their students are still sleepy, making the students easier to control. Memory tests prove that the more difficult classes should be in the afternoon when teenagers are most wide awake.
The Monkseaton school officials are encouraged by the results and plan on voting to make it a permanent change.What’s the best title of this passage?

Since the 1970s，scientists have been searching for ways to link the brain with computers. Braincomputer interface (BCI) technology could help people with disabilities send commands to machines.
Recently，two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne，Switzerland，demonstrated (展示) a small robotic wheelchair directed by a person’s thoughts.
In the laboratory，Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thougts.
“Our brain has billions of nerve cells.These send signals through the spinal cord(脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles，” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.”
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof.Millan，the team leader，says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories：communication，and controlling devices. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients，so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.How did Tavella operate the wheelchair in the laboratory?
| A．By controlling his muscles. |
| B．By talking to the machine. |
| C．By moving his hand. |
| D．By using his mind. |
Which of the following shows the path of the signals described in Paragraph 5?
| A．scalp→computer→cap→wheelchair |
| B．computer→cap→scalp→wheelchair |
| C．scalp→cap→computer→wheelchair |
| D．cap→computer→scalp→wheelchair |
Which of the following would be the best title for the text?
| A．Switzerland，the BCI Research Center |
| B．New Findings about How the Human Brain Works |
| C．BCI Could Mean More Freedom for the Disabled |
| D．Robotic Vehicles Could Help to Cure Brain Injuries |
Last month, Justin Valdez, a college student, was shot in a subway station in San Francisco. The surveillance video(监控录像) showed that before Justin was killed, the killer pulled out his gun several times, and even wiped his nose with it. However, nobody noticed the killer. The surrounding passengers all focused on their cell phones.
We may see the same scene everywhere in our life: in subway stations, restaurants, elevators and so on, people are watching their cell phones. From a family reunion to a date with a friend, people couldn’t stop checking their twitter and facebook on the cell phones and ignoring the persons in front completely, Phubbing(低头症) not only involves young people, but also the elderly and kids.
“Phubbing” is a new term which comes from the words “phone’’ and “snub(冷落)”. It describes the habit of snubbing someone in favor of a cell phone.

A Stop Phubbing campaign website has been set up. You can find the slogan of the website as follows: “stop twittering, stop posting photos…enjoy your food, enjoy the music and respect others.”
Phubbing appears harmless. However, it does influence our life. Jimmy, an epicure(美食家), wrote in his blog: “I can no longer focus on what I am eating since I started twittering. My skill of food photography has improved very fast, while my interest in food drops as a result.”

Alibaba started taking the lead in China, simply enough, by connecting big Chinese manufacturers(制造商)with big buyers across the world. Its business-to-business site, Alibaba.com allowed business to buy almost everything. Alibaba’s advantage wasn’t hard to identify size. Alibaba is just big, even by Chinese standards. Its marketplaces attract 231 million active buyers, 8 million sellers, 11.3 billion orders a year—and Alibaba is just the middleman. It encourages people to use its markets—not charging small sellers a percentage of the sale.
If you want a quick look into the influence of Alibaba on daily Chinese life, take my experience. I moved to Beijing almost a year ago and quickly got tired of visiting small stores across the crowded, polluted city of 20 million people in search of new electronics, bathroom furnishings, and anything else my wife wanted. “You’re looking for what exactly? Why not try it? ” my Chinese teacher asked me one day. With that, my wonderful new relationship with Alibaba began.
Alibaba’s original business-to-business model now is secondary to consumer buying. Chinese retail（零售）buying makes up 80% of Alibaba’s profit, and leading that group is Taobao, with 800 million items for sale and the most unbelievable selection of things you’ll ever find. TMall.com is Alibaba’s other big site, where you can find brand name goods from Nike and Unilever near the lowest prices.
What I have a hard time explaining to friends and family back in the U.S. is how China has gone beyond traditional shopping—big-box retailers especially —in favor of online purchases on Taobao and a few other sites. In smaller towns than Beijing, where big retailers have not yet traveled, shopping online is shopping, and shopping is Taobao.
I have a list of some of my recent purchases on Taobao for a sense of how extensive the marketplace is. Almost everything arrived a day or two after ordering with free shopping. I’m not even a big buyer, because I need friends to help me search the Chinese-language site. When I was searching my purchase history on my Chinese teacher’s iPad, which helps me buy goods, I looked through with great difficulty about 10 of her purchases for every one of mine.Alibaba’s advantage mainly lies in ___________.
| A．its big size |
| B．its business-to-business service |
| C．its not charging small sellers |
| D．its low price |

| A．Alibaba is of middle size among all the online sites |
| B．Alibaba will continue to develop. |
| C．Alibaba stands out as the best online site. |
| D．Alibaba acts as a bridge between the buyers and sellers. |
What does the underlined word “it” in Paragraph 2 refer to?
| A．a new store | B．Alibaba |
| C．a business | D．a foreign website |
What can be inferred from the passage?
| A．The author’s Chinese teacher is also an online purchase lover. |
| B．Taobao has no obvious advantage over other similar online sites. |
| C．Alibaba’s business-to-business service earns more money than retail now. |
| D．TMall.com provides more profit than Taobao. |
Norm Pethrick, a 36-year-old man in Australia’s northern city Darwin, was praised on Thursday for jumping onto a crocodile’s back to save his wife Wendy at Litchfield National Park, a popular tourist spot southwest of Darwin, a local newspaper reported.
