Over the last several years, Japanese and Korean beauty services have moved over to the North American market, which may partly explain why we’re now seeing activated charcoal (活性炭) in so many products - it has long been used in those countries as a cleaning ingredient (原料). But there’s another reason for its recent popularity: marketers know we are suckers for anything novel. “Activated charcoal is highly popular on the Internet,”says dietitian Abby Langer. The charcoal in activated charcoal is created by burning carbon-rich materials such as wood and bamboo, turning them into a concentrated black material. Then the charcoal is”activated”by steaming it at high temperatures, which opens up its carbon structure and makes it full of very small holes that can join together dirt, oil, and bacteria on its surface.

However, does it really improve beauty and other products? Here’s the thing: despite some stories of clear skin from nutritionists, personal trainers and movie stars, there is no clinical evidence for the effectiveness of activated charcoal as a beauty quality. Likewise, there is no good evidence showing that using charcoal products for health in the mouth will make your breath fresher or teeth whiter. In a CBC story last year, the Canadian Dental Association wouldn’t recommend using charcoal products because they have no proven health benefits, and they may even damage your enamel(the hard white outer layer of your teeth).

Activated charcoal also enjoys a high status in the food industry, being used by restaurants and food brands to turn a long list of food and drinks a deep black color. So before you shell out extra cash for a lemonade with activated charcoal, remember that you’re paying for the look - there’s no scientific evidence for the”detox(排毒)” action it promises.

There are some proven uses for this stuff, though. In the emergency room. doctors sometimes feed some activated charcoal to patients who have been poisoned. If it’s done quickly - ideally within minutes but up to an hour after being poisoned, while the poisonous substance is still in the stomach - it prevents the body from absorbing it. So yes, activated charcoal might save your life. However, everyday users should know that it doesn’t combine with alcohol, so it won’t magical erase the effects of late-night drinking. Also, be aware that it doesn’t tell the difference between the bad and the good: it will mix with blood pressure medication pills and get them through your system, too.

1. What does the underlined part in Paragraph 1 mean?
A.Are crazy aboutB.Tend to ignore
C.Pretend to knowD.Are doubtful about
2. What’s the Canadian Dental Association’ s attitude towards activated charcoal Products ?
A.Supportive.B.Tolerant.
C.Unconcerned.D.Disapproving.
3. Which one is a tested use for activated charcoal?
A.Controlling blood pressure.
B.Keeping food and drink fresh.
C.Absorbing poison in the stomach.
D.Reducing the effects of overdrinking.
4. Which of the following can be the best title for the text?
A.Activated charcoal is getting popular
B.Here are some uses of activated charcoal
C.Is activated charcoal actually good for you?

【推荐1】Sandra Bullock turned 51 last month. But because she looks exactly the same as she did in Miss Congeniality, a movie filmed back in the 20th century, everyone calls her “ageless.” Bullock is just one of a number of stars in their 40s and 50s who’ve had birthdays recently but have not gotten older, unlike the rest of us in their age group. Take Halle Berry. One website put a photo of her 20 years ago next to one of the newly 49-year-old Berry and dared us to choose which was which. “This Is What 49 Looks Like,” it said. Seriously, if that’s what 49 looks like, I must be 71.
However, even a generation ago, famous faces evolved. Look at a picture of Grace Kelly at age 52 in the early 1980s. She looks like a beautiful middle-aged woman. Today she’d look old for her age.
The goal now is to prevent aging while you are still young, using all the magical nonsurgical options medicine has to offer. Eventually these techniques will become less expensive, and ordinary people my daughter’s age will have them. Already anti-aging is starting to be considered maintenance, like coloring your hair. My friends and I find ourselves openly debating techniques that we used to make fun of. Does fat-freezing work? How much time do you have to spend in the gym to keep the body of a 35-year-old after 50? It’s all so exhausting. But members of the next generation have it tougher. They’ll have to ask themselves whether they want to spend their youth trying not to get old. I’ve already seen “Sexy at 70” headlines. Will everyone be expected to go to their graves(坟墓) looking hot?
I also have to wonder what else we are slowing along with age. How do you move on if you’re working so hard to stay the same? And besides, if you’ve known the ache of watching a daughter pack up for college, you know you can’t stop the clock.
1. In the author’s eyes, Sandra Bullock ________.
A.doesn’t deserve her name
B.doesn’t look her age at all
C.behaves like a young woman
D.looks younger than Halle Berry
2. The example of Grace Kelly is given to show ________.
A.physical beauty never lasts long
B.there is no such thing as agelessness
C.people’s attitude towards aging has changed
D.stars pay too much attention to their appearance
3. Where do the author’s concerns about anti-aging techniques lie?
A.They expose people to danger.
B.They make people feel stressful
C.They are too expensive for ordinary.
D.They encourage comparisons among people.
4. What’s the purpose of the text?
A.To show the burden of youth.
B.To offer tips on how to look hot.
C.To advise people to accept aging.
D.To comment on some famous stars.

【推荐3】After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping makes it possible for your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the one before. As you sleep, your body relaxes little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.
Although your mind slows down, you will dream from time to time. Scientists who study sleep point out that when you are dreaming, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people suggest breathing very slowly and very deeply. Other people believe that drinking warm milk will make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.
1. The text makes us know that not getting enough sleep might make you _________.
A.suffer form poor healthB.enjoy more
