“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine, newspaper, radio and television ads, promising new shapes and new looks to those who buy the medicine or the device of such products say they can shape the legs, slim the face, smooth wrinkles, or in some other way to beauty or desirability.
Often such products are nothing more than money-making things for their promoter. The results they produce are questionable, and some are dangerous to health.
To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA(Food Drug Administration)can require proof (证明)under the Food, Drug, and Cosmetic Act that it is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action ,including seizure (查封) of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings (法律诉讼), and new devices appear continually. Before buying, it is up to the consumer to judge the safety or effectiveness of such items.
It can be inferred that ads mentioned in the text are ______.

A．objective

B．costly

C．unreliable

D．illegal

Which of the following is true according to the text?
A. The court is in charge of removing dangerous product.
B. New products are more likely to be questionable.

Even when you’re extremely busy, you aren’t using your time with 100% efficiency. There are gaps in everyone’s schedule where they aren’t doing anything important. Even if your schedule has no gaps, there is probably lots of time where you aren’t working as fast or as effectively as you possibly could.
Why aren’t you completely efficient? It’s because time isn’t the limiting factor. If it were the limiting factor, people could work non-stop without breaks or any unproductive distractions(消遣). Instead, people, even those who are highly productive, need to take breaks, occasionally procrastinate(拖延) and slow down on tasks throughout the day.
The real and most important limiting factor for productivity is your energy levels to pay attention. Energy levels limit your productivity because when you’re tired, you can have ample time and still not get everything done. Your attention ability is also limited, because even if there are a million things that need to be done, you can only focus on one or two at a time.
You might not be able to insert another 4-5 hours into your schedule without making some sacrifices. But even extremely busy people can add an hour or two into their schedule without cancelling anything. The reason it’s hard to “find time” isn’t a lack of time. It’s because you don’t have enough energy left to focus on something else that needs to fit into your day.
I first suspected time wasn’t the real problem during an extremely busy period in my life over a year ago. I was insanely （发疯地）busy, but at that time I still exercised regularly. I had daily to-do lists with over twenty items, and I still found time to exercise. However, after a few weeks off, due to illness, I stopped exercising. I was not busy by any standards, in fact, my schedule was incredibly light. Despite this free time, I found it hard to find time to exercise. It seemed to get pushed later and later into my schedule until it was gone. How can I explain this odd experience? I believe you have known it.
If someone can’t work with 100% efficiency, the most important limiting factor is ________.

A．a schedule without gaps	B．breaks and distractions
C．the limited time	D．the limited energy

According to paragraph 4, everyone, including the extremely busy people, can ___________.

She belongs to no one but the whole world that can understand her language. Her music is appreciated across the globe but it is Singapore, China, Thailand and Britain that have helped to shape her talent.
Violinist, Vanessa-Mae, best known for her pioneering mix of pop and classical music, has just completed her Asian tour. She has a magic power that has attracted an audience from around the world but the violin genius has always drawn fans by blazing a new trail.
“I don’t like playing it safe, I like jumping into new styles,” she said. She started her Asian performance tour in China’s Hong Kong on September 19 and visited the Malaysian capital of Kuala Lumper. The tour, aiming to promote her new album, “The Best of Vanessa-Mae”, ends in Thailand’s capital Bangkok on September 30.

If a diver surfaces too quickly, he may suffer the bends. Nitrogen (氮) dissolved (溶解) in his blood is suddenly liberated by the reduction of pressure. The consequence, if the bubbles (气泡) accumulate in a joint, is sharp pain and a bent body — thus the name. If the bubbles form in his lungs or brain, the consequence can be death.
Other air-breathing animals also suffer this decompression (减压) sickness if they surface too fast: whales, for example. And so, long ago, did ichthyosaurs (鱼龙). That these ancient sea-animals got the bends can be seen from their bones. If bubbles of nitrogen form inside the bone they can cut off its blood supply. This kills the cells in the bone, and consequently weakens it, sometimes to the point of collapse. Fossil(化石)bones that have caved in on themselves are thus a sign that the animal once had the bends.
Bruce Rothschild of the University of Kansas knew all this when he began a suty of ichthyosaurs bones to find out how widespread the problem was in the past. What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompession over the 150 milllion years. To this end, he and his colleagues traveled the world’s natural-history museums, looking at hundreds of ichthyosaurs from the Trassic period and from the later Jurassic and Cretaceous periods.
When he started, he assumed that signs of the bends would be rarer in younger fossils, reflecting their gradual evolution of measures to deal with decompression. Instead, he was astonished to discover the opposite. More than 15% of Jurassic and Cretaceous ichthyosaurs had suffered the bends before the died, but not a single Trassic specimen showed evidence of that sort of injury.
If ichthyosaurs did evolve an anti-decompression means, they clearly did so quickly — and, most strangly, they lost it afterwards. But that is not what Dr Rothchild thinks happened. He suspects it was evolution in other animals that caused the change.
Whales that suffer the bends often do so because they have sufaced to escape a predator (捕食动物) such as a large shark. One of the features of the Jurassia oceans was an abundance of large sharks and crocodiles, both of which were fond of ichthyosaurs lunches. Trassic oceans, by contrast, were mercifully shark-and crocodile-free. In the Trassic, then, ichthyosaurs were top of the food chain. In the Jurrasic and Cretaceous, they were prey (猎物) as well as predator —and often had to make a speedy exit as a result.

A．A twisted body.

B．A gradual decrease in blood supply.

C．A sudden release of nitrogen in blood.

D．A drop in blood presure.
