SOME teenagers take up smoking during the holidays either because they become "rich" enough to afford a pack of cigarettes or they think they look "cool". Everyone knows that "smoking is bad for you", but do smokers really know what the health warnings mean to them?
Smoking, the world's second leading cause of preventable death, kills 4.9 million people a year, the United Nations said on February 27. The world has about l.2 billion smokers and World Health Organization surveys show that about 20 per cent of them are children aged between 13 and 15 years old.
On the same day, a global treaty(公约) aimed at encouraging children not to smoke and help people kick the habit came into force. This is the first worldwide agreement on a public health issue. It will see strong warnings added to cigarette packets and a ban on all tobacco advertising.
Young smokers may think little of the health effects of smoking. But smoking can stop them from making friends, as most non-smokers don't like being around smokers.
"I feel sick when I see people of my age smoke. Smokers make themselves look less educated ," said Shi Qingyu, a Senior 3 student at Luanxian No 1 High School in Hebei Province. Once while on a bus, he asked a girl who was smoking next to him to put out her cigarette.
For Wang Gezhu, a Senior l girl from Wuxi Furen High School in Jiangsu Province,boys who smoke are less attractive.
"Boys that smoke may think they are cool or impressive, but I think they look weird(怪异的) compared to other ordinary students in my eyes. They only do what others won't risk doing," Wang said.
Every one wants to impress others, but there are ways to show off other than smoking.
On February 26, around 200 students from across the country gathered in Beijing to be awarded for their outstanding performance in the 2004 "Sunflower Cup". The programme included several contests in writing, calligraphy (书法), drawing and painting. It aimed to encourage students to take part in meaningful activities so that they could spend their free time developing healthy habits and hobbies.
"Teenagers are energetic and quick to learn, both good and bad things. For the sake of their own health, teenagers should learn to say no to their first cigarette because life as a smoker is a life of addiction. You can't quit," said Wang Zhengqi, deputy secretary-general (副秘书长) of the Chinese Association on Smoking and Health.

IT'S a mystery that has puzzled scientists. Five years ago, researchers found an area in the Atlantic Ocean seabed, where a part of the Earth's outer layer, or crust（地壳）, is missing. A thick layer of dark green rock, which is usually found deep inside the planet, lies exposed.
The crust, mantle(地幔) and core（地核） are the main layers that make up the planet. The mantle rests between the crust and the core.
Last month, a team of 12 British scientists set off on a six-week trip to study the hole in the crust.
The hole is about 4,800 meters below sea level and is believed to be more than 48,000 meters long and more than 48,000 meters wide. Scientists think that there are other nearby gaps. "It is like a window into the interior (内部) of the Earth," says scientist Bramley Murton, who is part of the research team.
The site where the hole is located is part of a ridge (山脉) of undersea volcanoes. There, two of the plates that make up the Earth's surface meet. The plates are always moving. When the plates move away from each other, lava rushes up from the mantle to fill the gap and form a new crust. But this did not happen in the area where the hole is located.
The hole is giving researchers a good opportunity to study what's below the Earth's surface. The team will use a special robotic tool to film the area and get samples of the exposed mantle. They hope to study everything from the chemistry of the oceans to how the Earth's surface behaves under the sea.
What's the title for the passage?

A．How to study the earth.

B．The formation of the earth.

C．A hole in the earth.

D．Studying the inside of the earth.

For the main layers of the earth, which one is right?

A．crust, mantle, core	B．seabed, crust, mantle
C．seabed, mantle, core	D．crust, seabed, core

How does the hole come into being?

A．It's because of a volcano eruption.

B．It's because of the plates movements

C．It's because lava rushes up from the mantle

D．It's not clear from the passage.

By studying the hole, the scientists want to do the following except____.

A．knowing what's below the Earth's surface

B．getting samples of the exposed mantle

C．getting the film of the hole

D．studying the chemistry of the oceans

Every day we are bombarded with images, videos, music and news. In this age of visual and aural hyper-stimulation, the medium of radio is making a phenomenal comeback.
“We're at the dawn of a golden age of audio," said US-based podcaster Alex Blumberg in an article in The Sydney Morning Herald. In the last month alone, 15 percent of US adults listened to a radio podcast. These statistics, released by Edison Research, reveal the successful evolution of traditional radio broadcasts to the present day's digital podcast format. The term "podcast," was coined in 2004, but the trend only started gaining mainstream popularity in recent years. Since the leap in consumer demand for smartphones and tablets, podcast subscription rates have only accelerated.
The appeal of the podcast partially resides in its multiplatform delivery and on-demand capabilities. You can tune in during those extra minutes of the day when you're walking to the shops, waiting in a queue or riding the subway. Similar to television shows, podcasts are generally free to download and most offer new content every week.
Donna Jackson, 22, Sydney university media graduate, listens to podcasts two or three times a week, via iTunes .”I listen while I'm pottering around the house doing something else. It makes completing a boring task a lot more enjoyable..... And it's an easy way of keeping in touch with what's going on in the rest of the world," she said.
Unlike television and music, the audio format has the potential to create a deep impression on readers. Blumberg says this comes down to the podcast's ability "to create intimacy and emotional connection." Sydney University undergraduate Hazel Proust, major in social work and arts, agrees. "When you're tuned in, it feels as if the voice of the podcast's narrator is talking directly to you. It's comforting," said Proust.
From the passage, we can learn that____.

A．Radio is developing more quickly than mediums with images, videos, music and news.

B．Podcast has its origin in the traditional radio broadcasts.

C．In the last month alone, 15 percent of world adults listened to a radio podcast.

D．Podcast was becoming popular from 2004.

By saying "We're at the dawn of a golden age of audio," Alex Blumberg wants to
Tell us that ______

A．Traditional radio broadcasts will be loved by people again.

B．Radio has attracted more people than TV and other forms of media .

C．Radio will be more and more popular in the form of podcast.

D．The Sydney Morning Herald will help radio become popular again.

For podcast, which is wrong?

A．You can listen to it at any time and any place.

B．You can download it without pay.

C．You can learn new content every week from it.

Your glasses may someday replace your smartphone, and some New Yorkers are ready for the change. Some in the city can't wait to try them on and use the maps and GPS that the eyewear is likely to include.
" I'd use it if I were hanging out with friends at 3 a. m. and going to the bar and wanted to see what was open," said Walter Choo, 40, of Fort Greene.
The smartphone-like glasses will likely come out this year and cost between $250 and $600, the Times said, possibly including a variation of augmented(增强的) reality, a technology already available on smartphones and tablets (平板电脑) that overlays information onto the screen about one's surroundings. So, for example, if you were walking down a street, indicators would pop up showing you the nearest coffee shop or directions could come into view right on the sidewalk in front of you.
"As far as a mainstream consumer product, this just isn't something anybody needs," said Sam Biddle, who writes for Gizmodo.com. " We're used to having one thing in our pocket to do all these things," he added, "and the average consumer isn't gonna be able to afford another device (装置) that's hundreds and hundreds of dollars. "[
Google publisher Seth Weintraub, who has been reporting on the smartphone-like glasses since late last year, said he is confident that this type of wearable device will eventually be as common as smartphones. "It's just like smartphones 10 years ago," Weintraub said. "A few people started getting emails on their phones, and people thought that was crazy. Same kind of thing. We see people bending their heads to look at their smartphones, and it's unnatural," he said. "There's gonna be improvements to that, and this a step there. "
One of the possible functions of the smartphone-like glasses is to ____.

A．program the opening hours of a bar
