When it comes to your skin, there is an extremely important fact that you must keep in mind: Your skin is the largest organ of your body. As an obvious result, skin health and maintenance(保养) is vital. Your skin does everything from protecting you from the elements to assisting you with breathing. Your skin keeps your body hydrated(含水的) and regulates your body's temperature. In the end, this really is only the beginning of all of the various vital functions that your skin provides to you.
Despite the extreme importance of a person's skin, the reality is that many people simply do not pay much attention to issues relating to the health of their skin. With that in mind, there are some prime tips and pointers that you must always keep in mind when it comes to the health and protection of your skin.
Protection against harmful rays from the sun is one of the most important steps that you need to take. With this in mind it is vitally important that you make certain you use solid protection when you go out into the sun.
Your diet also has a direct effect on the health of your skin. The most important aspect of your diet in relation to the health of your skin is to make certain that you eat a proper amount of food items that contain the proteins and nutrients necessary for cellular maintenance, repair and regeneration(再生). With this in mind, your skin cells actually rely on a sufficient amount of carbohydrates.
Water is also important to the Health of your skin. While you certainly have heard it before, it actually is true that you should drink at least eight 8-ounce glasses of fresh and pure water every day. There are many health benefits you can get from drinking water daily, including maintaining healthy skin.
Finally, when it comes to the health of your skin today and into the future you should avoid smoking all together. In addition, you should drink alcohol only in moderation. Both smoking and too much alcohol consumption can negatively affect the health of your skin in significant ways.

第三部分:阅读理解（共20小题;每小题2分, 满分40分）
阅读下列短文，从每篇短文后所给各题的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
Mr. Whitson taught sixth-grade science. On the first day of class, he gave us a lecture about an animal called the Cattywampus, a nocturnal (夜间活动的) animal that was wiped out during the Ice Age. He passed around a skull as he talked. We all took notes and later had a quiz.
When he returned my paper, I was shocked. There was a big red “X” through each of my answers. There had to be some mistakes! I had written down exactly what Mr. Whitson said. Then I realized that everyone in the class had failed. What had happened? Very simple, Mr. Whitson explained. He had made up all that story about the Cattywampus. The information in our notes was, therefore, incorrect. Did we expect credit for incorrect answers? Needless to say, we were outraged. What kind of text was this? And what kind of teacher is he?
We should have figured it out, Mr. Whitson said. After all, at the very moment he was passing around the Cattywampus skull (in truth, a cat’s), hadn’t he been telling us that no trace of the animal remained? He had described its amazing night vision, the color of its fur and any number of other facts he couldn’t have known, he had given the animal a ridiculous name, and we still hadn’t been suspicious. The zeroes on our papers would be recorded in his grade book, he said. And they were. Mr. Whitson said he hoped we would learn something from this experience. He told us not to let our minds go to sleep, and to speak up if we ever thought he or the textbook was wrong.
We carded our new skepticism (怀疑主义) into all our classes. This caused problems for the other teachers, who weren’t used to being challenged. Our history teacher would be lecturing about something, and then there would be clearings of the throat and someone would say “Cattywampus”.
If I’m ever asked to propose a solution to the crisis in our schools, it will be Mr. Whitson. I haven’t made any great scientific discoveries, but Mr. Whitson’s class gave me and my classmates something just as important: the courage to look people in the eye and tell them they are wrong. He also showed us that you can have fun doing it.
51．The best title for this passage would probably be _______.
A. Cattywampus
B. An interesting and unforgettable Lesson
C. A new teaching method
D. The Best Teacher I Ever Had
52．The underlined word outraged in the second paragraph here means _______.
A. angry B. excited C. disappointed D. discouraged
53．From this passage, we know that Mr. Whitson was a teacher _______.
A. difficult to get along with B. creative in teaching
C. fond of being challenged D. full of energy and enthusiasm
54．We can infer from the passage that _______.
A. teachers and textbooks are not always right
B. Cattywampus could be found in the Ice Age
C. the history teacher didn’t like to be challenged
D. Mr. Whitson always made a bad impression on his students

Pupils are ordered not to wade into ankle-deep water unless teachers first carry out a full risk assessment and put“proper measures in place”.
Staff are expected to check rivers, ponds and the sea for currents and rocks before allowing children to dip their feet.
Guidance issued to schools warns that any“impromptu (事先无准备的) water-based activities”could pose dangers to children.
The recommendations were outlined in a document-available to all 21,000 schools in England — to help teachers organize more school trips. Advice from the Department for Children, Schools and Families is intended to cut red tape (官样文章) and give staff practical tips.
But the guidance caused argument after teachers were presented with a series of orders surrounding swimming and the use of minibuses.
It said:“Swimming and padding or otherwise entering the waters of river, canal, sea or lake should never be allowed as an impromptu activity. The pleas of young people to bathe — because it is hot weather, for example, should be resisted where bathing has not been prepared for.”
“In-water activities should take place only when a proper risk assessment has been completed and proper measures put in place to control the risks.”
Teachers are urged to check the weather, currents, weeds, rip tides, river or sea beds and breakwaters before allowing children into the water. No child should be able to swim deeper than waist height, the guidance added.
Margaret Morrissey, from campaign group Parents Outloud, said:“Wading out into the ocean is one thing but there’s nothing wrong with padding where the waves break.”
“Part of children’s learning is to walk along the water’s edge and get your feet wet. There are dangerous currents further out and you stay at the edge.”
She added:“I want to see schools and youth groups taking advantage of opportunities that learning outside the classroom can provide.”
But the Department for Children, Schools and Families said teachers had to plan activities carefully.
“We are not banning padding,”said a spokeswoman.“We have seen cases in the past where things have not been planned and assessed for the risk. Unplanned activities around water can be dangerous.”
67．Guidance issued to schools in England gives the information that _________.
A．school trips to oceans are forbidden in the country
B．school swimming pools should be surrounded with fence
C．school staff must plan water-based activities carefully
D．school children shouldn’t have a walk along river banks
68．Advice from the Department for Children, Schools and Families shows us that _________.
A．they are strongly against the guidance
B．they are fond of the outline of the guidance
C．they don’t understand the aim of the guidance
D．they want the guidance to become more useful
69．To the guidance, Margaret Morrissey holds the opinion that _________.
A．oceans are dangerous place for children to visit
B．young people should be encouraged to learn outside
C．children should learn padding in rough ocean alone
D．schools should stop students from walking along beaches
70．Which of the following can be the best title for this passage?
A．No padding on school trips, children told.
B．No walking along the rivers, teachers told.
C．No swimming after school, parents told.
D．No learning out of school, students told.

Watching bison up close is fascinating, like watching a grass fire about to leap out of control. With their huge, wedge-shaped heads and silver-dollar-size brown eyes, the 2,000-pound animals are symbols of another place and time. More than 100 bison now roam the 30,000-acre American Prairie Reserve in eastern Montana — the first time they’ve inhabited that region in a century. Direct descendants of the tens of millions of bison that once populated the Western plains, they represent an epic effort： to restore a piece of America’s prairie to the national grandeur that Lewis and Clark extolled two centuries ago. During that famous expedition across the Western states to the Pacific, the two explorers encountered so many bison that they had to wait hours for one herd to pass.
In order to protect what’s here and reintroduce long-gone wildlife (something the World Wildlife Fund is helping with), the American Prairie Foundation began purchasing land from local ranchers in 2004. It now owns 30,000 acres and has grazing privileges on another 57,000. Its goal over the next 25 years is to assemble three million acres, the largest area of land devoted to wildlife management in the continental United States.
Already, herds of elk, deer, and pronghorn antelope roam the grasslands, where visitors can camp, hike, and bike. Cottonwoods and willows are thriving along streams, creating habitats for bobcats, beavers, and other animals.
Not everyone shares APF’s vision. Some residents of Phillips County (pop. 3,904) worry that the area could become a prairie Disneyland, overcrowded with tourists. But the biggest obstacle is the ranchers themselves, whose cattle compete with prairie dogs and bison for grass and space.
“People like me have no intention of selling their ranches,”says Dale Veseth, who heads the Ranchers Stewardship Alliance of 35 families in Phillips County and whose family has been ranching here since 1886.“They’ve been a labor of love through the generations.”Instead, he wants APF to pay or subsidize ranchers to raise bison. This would be far less costly for the foundation, he argues, than buying the land directly.
63．If you go to the American Prairie Reserve in eastern Montana, you will see ________.
A．the burning fire moving across the grassland
B．hundreds of bison travelling through the prairie
C．tens of millions of bison occupying the farmland
D．groups of experts examining the dead bison
64．What measures have been taken to protect the wildlife by APF?
A．They have borrowed much money and developed new habitat.
B．They have hired many farmers to raise bison on their farms.
C．They have turned grassland into Disneyland to attract tourists.
D．They have bought large land from farmers for bison to live on.
65．The underlined word“subsidize”in this passage means ________.
A．give money to B．borrow money from
C．provide land to D．exchange land with
66．Which would be the best title for this passage?
A．The exciting scenery in eastern Montana
B．Great changes in raising bison in America
C．The return of the American prairie
D．The challenge in protecting the grassland

The days of the hunter are almost over in India. This is partly because there is practically nothing left to kill, and partly because some steps have been taken mainly by banning tiger-shooting to protect those animals which still survive.
Some people say that Man is naturally a hunter. I disagree with this view. Surely our earliest forefathers, who at first possessed no weapons, spent their time digging for roots, and were no doubt themselves often hunted by meat-eating animals.
I believe the main reason why the modern hunter kills is that he thinks people will admire his courage in overpowering dangerous animals. Of course, there are some who truly believe that the killing is not really the important thing, and that the chief pleasure lies in the joy of the hunt and the beauty of the wild countryside. There are also those for whom hunting in fact offers a chance to prove themselves and risk death by design; these men go out after dangerous animals like tigers, even if they say they only do it to rid the countryside of a threat. I can respect reasons like these, but they are clearly different from the need to strengthen your high opinion of yourself.
The greatest big-game hunters expressed in their writings something of these finer motives. One of them wrote：
“You must properly respect what you are after and shoot it clearly and on the animal’s own territory (领地).You must fix forever in your mind all the wonders of that particular day. This is better than letting him grow a few years older to be attacked and wounded by his own son and eventually eaten, half alive, by other animals. Hunting is not a cruel and senseless killing — not if you respect the thing you kill, not if you kill to enrich your memories, not if you kill to feed your people.”
I can understand such beliefs, and can compare these hunters with those who hunted lions with spears and bravely caught them by the tail. But this is very different from many tiger-shoots I have seen, in which modern weapons were used. The so-called hunters fired from tall trees or from the backs of trained elephants. Such methods made tigers seem no more dangerous than rabbits.
59．There is no more hunting in India now partly because ________.
A．it is dangerous to hunt there B．hunting is already out of date
C．hunters want to protect animals D．there are few animals left to hunt
60．The author thinks modern hunters kill mainly ________.
A．to make the countryside safe B．to earn people’s admiration
C．to gain power and influence D．to improve their health
61．What do we learn about the big-game hunters?
A．They hunt old animals. B．They mistreat animals.
C．They hunt for food. D．They hunt for money.
62．What is the author’s view on the tiger-shoots he has seen?
A．Modern hunters lack the courage to hunt face-to-face.
B．Modern hunters should use more advanced weapons.
C．Modern hunters like to hunt rabbits instead of tigers.
D．Modern hunters should put their safety first.
