One of today’s hottest topics among women (and to an extent among men too now) is anti aging and how to reverse the signs of age. The beauty industry has responded to this by offering a wide collection of anti aging creams and other anti aging products aimed at all pocketbooks, ranging from economical to highly priced.
And the question is “do any of these often much-vaunted(被过度吹嘘的) anti aging creams actually work?” And if they do, how precisely do they perform their miracles?
Well, the appropriate response to that is that they do work—after a fashion. There certainly are anti aging creams available for a relatively modest price that will reduce the appearance of wrinkles in a comparatively short period of regular application. But this really is the limit of their powers: they won’t actually undo skin damage or eradicate(根除) all signs of age; they will simply modify them, some more effectively than others.
The way they work is like so: they remove upper layers of dead skin cells and make deeper layers absorb water, serving to plump them up and make them look fuller and healthier. But since such anti aging creams only go skin deep, as it were, skin damage will reappear once you stop using the anti aging wrinkle(皱纹) cream.
This means fairly heavy regular use, which might be costly depending on your choice of product. However, if you can afford it or think it’s worth the cost, it won’t be such an issue. After all, what woman wants to look older than her years when looking good is so tied up with many women's self-esteem(自尊) and sense of identity.
A compromise(折中) solution for those on a tighter budget is to use the cheaper creams. In addition, it’s always wise to be a little experimental to make sure you end up with the one that suits your skin best.
So, to sum up: an anti wrinkle face cream will work within limits, depending on your objective.

We can express our feelings and needs by using body language. Cats can do that too. The ways that cats use their tails to show their feelings and needs are interesting.
Unlike dogs, which generally wave their tails to express good feelings, cats use their tails to send a lot of signals. When a cat waves its tail strongly from side to side, it may be a sign for us to leave it alone, or we may get scrathed (抓伤). Throwing a little toy for the cat to play with can get it relaxed. When a cat holds its tail upwards with a slight move, it means the animal is very happy to see its owner.
We all like to cuddle (依偎) inside our bed, and cats do that thing, too. Much as little children like to wrap (用……缠绕) their arms around their Teddy Bears, cats like to wrap their own tails around their bodies to get a sense of safety while asleep. If we notice a cat sleeping in such a position, we should not break its peace.
Usually the tip of the cat’s tail doesn’t draw our attention. But its particular position may also show the cat’s feelings. For example, a cat holding the tip of its tail pointed downwards may try to say that it is not feeling comfortable. So at this point, the cat not only feels angry, but also unsafe. This may again be a sign for us not to upset the cat in any way.
In conclusion, cats use their tails in many different, sometimes funny ways to send us messages, and we can learn to know more.According to the text, in which way are cats different from dogs?

Mother’s Day is the time you say “thank you” to your mom. Stop shopping at the store. Flowers and other things in stores are too common to mention. You can choose a special gift for Mother’s Day! Just try staying close to home—and heart —write a Mother’s Day poem for her.
Use your head. Think of special moments when you were a child, times you’ve shared with your mom, things she did for you, and why you love her. Write down how those moments influenced you. Write down everything you can think of. This is your inspiration for the poem.
Look at what you wrote and pick out those things that are connected(有联系的). See if any words rhyme(押韵). It’s fine to write a free poem(one without rhymes), but many people find poems with rhymes are easier to work with, easier to read and quite catchy(容易记住的). If no words rhyme but you want your poem to, try to find connecting words that can help connect memories.
Once you have a few sentences, put them in a good order. For example, you could start with a childhood memory and end with something you remember from last month.
Add a title that shows the feeling of the poem. Even something as simple as “For Mom” can work, although something more personal might be better.
Write it in pen if you have beautiful handwriting. Read the poem over breakfast on Mother’s Day, and then hand it to your mom. Let’s wait and see the smile and tears of happiness on her face.Why does the author suggest writing down everything you think of?
A. Because it will show your mother’s love.

| C．how to write a Mother’s Day poem. |
| D．how to write good poems for Christmas. |
A breathtaking trick potentially left over from our ancestors might be found in us — the ability to sense oxygen through our skin.
Amphibians, animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo.
Now the same oxygen sensors found in frog skins and in the lungs of mammals (哺乳动物) have unexpectedly been discovered in the skin of mice.
“No one had ever looked,” explained Randall Johnson, a biologist researcher.
Mice and frogs are quite distant relatives, so the fact they have these molecules (分子) in common in their skin suggests they might well be found in the skin of other mammals, such as humans.
“We have no reason to think that they are not in the skin of people too,” Johnson said.
These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen—a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1a genetically removed from their skin failed to produce this hormone (荷尔蒙) even after hours of such low oxygen.
These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia (贫血症) without injecting drugs, which make up a multibillion-dollar market, Johnson said.
Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. “It’s hard to say what exactly might be done, however—there’s a lot we don’t know yet,” Johnson explained.
The scientists detailed their findings in the April 18 issue of the journal Cell.Which of the following statements is TRUE according to the passage?
| A．It has long been expected oxygen sensors exist in mice’s skin. |
| B．People have to surf the Internet to read detailed findings. |
| C．It has been proved that these findings help treat lung diseases. |
| D．Johnson believes that Oxygen sensors also exist in human skin. |
One of the functions of the molecules mentioned above is _______.
| A． increasing level of oxygen | B．improving athletes’ performance |
| C．detecting oxygen | D．carrying oxygen around the body |
What is Johnson’s attitude to the application of the findings to the athletes’ training?
| A． Hesitating | B．Doubting | C．Positive | D．Negative |
The best title of the passage may be _______.
| A． Humans Might Sense Oxygen Through Skin |
| B．Frogs And Mice Are Distant Relatives |
| C．First Known Animal Breathes Through Skin |
| D．Great Findings Benefits Athletes A Lot |
Bad teeth can be painful -- and worse. They can even be deadly. Infections (感染) of the gums (牙龈) and the teeth can cause bacteria (细菌) to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk.
For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齿保健) he needed. He was twelve years old.
Experts at the National Institutes of Health say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow the growth of bacteria and acid production in the mouth.
But dentists say a baby's gums and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, only give the child water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently.
The use of fluoride (氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel (珐琅质) , the hard surface on teeth, to help prevent holes from forming.Which of the following can be used as the title of the passage?
| A．Concerns for Healthy Teeth of the Young |
| B．Causes of Teeth Problem |
| C．Importance of Healthy Teeth of All |
| D．Solutions to Teeth Problem |
What's the main idea of paragraph 4 and 5?
| A．How to develop babies' teeth. | B．How to keep babies' teeth clean |
| C．Why to protect babies' teeth | D．Why to keep babies' teeth clean |
The passage indicates that ______.
| A．Enamel is most widely used to protect teeth in the world |
| B．Breast milk can cure babies' bad teeth |
| C．Bad teeth may affect the health of adults and the young |
| D．Babies' teeth should be brushed once per day |
The writer uses the boy's death as an example to show that ______.
| A．not only adults but the young may suffer from teeth problem |
| B．the doctors should be responsible for the case |
| C．babies with bad teeth can easily die |
| D．the boy was not fed with his breast milk |
The long, lonely voyage of the Japanese ghost ship is over.
A US Coast Guard cutter poured cannon fire into an abandoned Japanese ghost ship that had been drifting since last year’s tsunami (海啸), sinking the vessel into waters more than 305 meters deep in the Gulf of Alaska and removing the danger it posed to shipping and the coastline on Thursday.
The cutter’s guns tore holes in the 164-foot Ryou-Un Maru, and then it began to take on water and lean to one side. In about four hours, the ship disappeared into the sea, said Chief Petty Officer Kip Wadlow.
The ship had no lights or communications system, and its tank was able to carry more than 7,570 liters of diesel fuel. Officials, however, didn’t know exactly how much fuel was aboard.
“It’s less risky than it would be running into shore or running into other ships,” coast guard spokesman Paul Webb said.
The US National Oceanic and Atmospheric Administration and the Environmental Protection Agency studied the problem and decided it is safer to sink the ship than let the fuel evaporate and pollute the sea environment.
Ryou-Un Maru was probably among the first wave of the 1.5 million tons of garbage of refrigerators, washing machines, televisions, roofs and fishing nets heading toward North America since last March when a magnitude-9.0 earthquake struck Japan.
As the coast guard was ready to fire on the vessel, a Canadian fishing vessel, the 19-meter Bernice C, claimed the rights to save the ghost ship in international waters.
Plans to sink it were paused so the Canadian crew could have a chance to take the stricken ship. A Canadian official with knowledge of the situation told the Associated Press that the Bernice C was unable to drag it.
Then the Canadian boat left, and once it was about 10 kilometers from the Japanese vessel, the Coast Guard began to fire, first with 25 mm shells, then a few hours later with ammunition (弹药)twice that size.
State officials have been working to test the danger of garbage including materials affected by a damaged nuclear power plant, to see if Alaska residents, seafood or wild animals could be affected.The plan to fire on the Japanese ghost ship was paused because ____________.
| A．the ghost ship was beyond the reach of the Coast Guard’s guns |
| B．state officials worried the ghost ship might give out radiation |
| C．the shells were not powerful enough to sink the ghost ship |
| D．a Canadian fishing boat wanted to save the ghost ship |
What’s the right order of the events related to the ship of Ryou-Un Maru?
a. Its long, lonely voyage came to an end.
b. The US Coast Guard sank it into the sea.
c. The ship began to float across the Pacific Ocean.
d. A big tsunami was caused by great earthquakes.
e. Bernice C claimed rights to save the ghost ship.
| A．d, c, e, b, a | B．a, b, d, c, e | C．c, e, d, a, b | D．b, a, d, c, e |
Which of the following could be the best title for the passage?
| A．Japanese ghost ship arriving at US |
| B．Tsunami garbage heading to US |
| C．Japanese ghost ship polluting the Pacific |
| D．Cannon fire sinking Japanese ghost ship |
