Like all vertebrates(脊椎動(dòng)物), fish have sense organs that tell them what is happening within their environment. The organs enable them to see, hear, smell, taste and touch.
A fish’s eyes differ from those of land vertebrates in several ways. For example, most fish can see to the right and to the left at the same time for the fact that a fish has no neck and so cannot turn its head. Fish also have no eyelids. For land vertebrates, eyelids(眼瞼)help moisten(使?jié)駶? their eyes and protect them from sunlight. A fish’s eyes are kept moist by the flow of water over them. They do not need to be shielded from sunlight because it is seldom extremely direct and bright underwater. Some fish have unusual adaptations of the eye. For example, a flatfish has two eyes on the same side of the head. A flatfish spends most of the time lying on its side on the ocean floor and so needs eyes only on the side that faces upward. The eyes of certain deep-sea fish are at the ends of short structures that stick out from the head. These structures can be raised upward, allowing the fish to see overhead as well as to the side and to the front.
A few kinds of fishes are born blind. They include certain species of catfish that live in total darkness in the waters of caves. Some of these fishes have eyes but no vision(視覺). Others lack eyes completely.
小題1:Why can’t a fish turn its head? (no more than 6 words)
_____________________________________________________________________
小題2:What can prevent land vertebrates’ eyes from sunlight? (no more than 3 words)
_____________________________________________________________________

小題1:Because it has no neck.
小題2:Their eyelids.
小題3:Because the flatfish has two eyes on the same side of the head.

Once upon a time, there was a poor boy working for a king day and night, but the king treated him badly. Every day, the boy went cold and hungry, so he ran away. Then one day, he met a big lion in the desert. The lion looked angry and the boy was afraid. He was about to run away when the lion said, “I am angry because there is a thorn(刺) in my foot.” “Don’t worry. I will help you.” So the boy sat down and helped to pull the thorn out. From then on, they became good friends.
One day, the king went hunting in the desert and he caught the lion! He threw it into a net. On his way back he saw the boy and caught him as well. “I will punish you for running away. I will throw you to the lion’s den(獸窩)!” said the king angrily. So he did! But to the king’s surprise, when the lion saw the boy, it lay down and smiled. The boy smiled too and put his arm around his friend. Greatly moved, the king let the boy and the lion go.

(1)Freezing weather can mean frostbite and hypothermia unless a person is prepared. Today we talk about how to stay warm, dry and safe.
(2)Frostbite is damage that happens when skin is exposed to extreme cold for too long. It mainly happens on the hands, feet, nose and ears.
(3)People with minor cases of frostbite that affect only the skin may not suffer any permanent damage. But if deeper tissue is affected, a person is likely to feel pain every time the area gets cold.
(4)If blood vessels are damaged, people can suffer a gangrene infection. Sometimes the only way doctors can treat an injury like this is to remove frostbitten areas like fingers and toes.
(5)Hypothermia is a condition that develops when the body cannot produce as much heat as it releases. Signs of hypothermia include uncontrollable shaking, very slow breathing and difficulty thinking clearly. Hypothermia can lead to death if the person does not receive help.
(6)To avoid cold-related injuries, here is a simple way to remember four basic steps to staying warm. Think of COLD -- C.O.L.D.
(7)The C stands for cover. Wear a hat and scarf to keep heat from escaping through the head, neck and ears. And wear mittens instead of gloves. In gloves, the fingers are separated, so the hands might not stay as warm as they would in mittens.
(8)The O stands for overexertion. Avoid activities that will make you sweaty. Wet clothes and cold weather are a dangerous combination.
(9)L is for layers. Wearing loose, lightweight clothes, one layer on top of another, is better than wearing a single heavy layer of clothing. Make sure outerwear is made of material that is water-resistant and tightly knit.
(10)________________. In other words, stay as dry as possible. Pay attention to the places where snow can enter clothing. These include the tops of boots, the necks of coats and the wrist areas of mittens or gloves.
(11)And here are two other things to keep in mind -- one for children and the other for adults. Eating snow might be fun but it lowers the body's temperature. And drinking alcohol might make a person feel warm. But what it really does is weaken the body's ability to hold heat.
(12)Next week on the Health Report: advice from experts about what to do, and not to do, to help someone who is injured by cold weather.
小題1:What’s the main idea of the passage?(in not more than 12 words)

小題2:What are the symptoms of hypothermia?(in not more than 10 words)

閱讀下面的短文,并根據(jù)短文后的要求答題。(請注意問題后的字?jǐn)?shù)要求)。
Many students find it hard to make friends when they are in high school. Keeping my suggestions in mind may give you a hand. They certainly helped me, and by the end of my three years of high school, I had formed my group of friends, with whom I still keep in touch now.
Here are my tips:
Say hello anytime I see an acquaintance(相識(shí)的人).
Because I was always smiling and greeting the people I knew, people naturally thought I was friendly(though I am not naturally sociable). And high school students want to be friends with sociable people.
Take the first step.
All the girls there already knew each other—they didn't need another friend. But I did, so I had to make the effort. I had to be the first one to invite somebody to go to a movie with me, or come to my house. Once I did that they started to respond with the same thing.
Use classes to get to know people.
I met most of my first friends because I sat next to them in class. Class(before, after, or even during class time)is a great opportunity to begin a conversation. For example, ask for help about homework.
Make friends slowly.
I couldn't get discouraged (泄氣的) when it took a while to make friends.It really takes some time to make new friends. In a word, ________________________.
 Above all, remember that it can and will get better. You may have to work a little to make your high school experience a great one, but it's really worth it!
小題1: For what purpose does the writer write this passage?(Please answer within 15 words.)
____________________________________________________________________
小題2: Which sentence in the passage is the closest in meaning to the following one?
I was believed to be sociable because of my friendly attitude towards others.
_____________________________________________________________________
小題3:Fill in the blank with a sentence.(Please answer within 10 words.)  _____________________________________________________________________
小題4: Which piece of advice does the following sentence belong to? (Write in detail)
Everybody should make friends patiently in high school.

小題5:Translate the underlined sentence in the first paragraph into Chinese.    ___________________________________________________________________

[l] Scientists guess that 80% of a person's weight gain comes from genetics and 20% comes from the person's environment. By 1998, more than 130 genes and gene neighbors were found to have some link to weight gain or weight loss in people. These different genes can either work all together or work in groups. This means that different people may ___________________or lose weight with difficulty for different reasons.
[2] One example of these different kinds of combinations is a family of genes that allows people to change extra fat into heat instead of storing the fat in the body. Animals which have this same family of genes do not gain weight easily as other animals. Other genes may affect how quickly the stomach lets the brain know that it is full. If these genes slow down the passage of this information, people may eat more than they really need. Genes are also thought to be linked with a person’s fidgets in a day. Fidgeting is small movements of a person's hands, feet, arms or legs usually when the person is nervous or excited. Fidgeting actually uses a lot of energy over a day and his energy usually comes from burning fat.
[3] In one experiment about weight gain, researchers wanted to see how much energy different people used when they were resting. People in the experiment were asked to lie on a bed and not move for 40 minutes. Researchers then measured the energy the person used for breathing. They found that different people in the study used very different amounts of energy for this one job, breathing. Researchers calculated that some people in the study burned 1,067 calories per day while others burned up to 3,015 calories. Those people who burn fewer calories doing normal work or exercise have a slow metabolism(新陳代謝).

A woman saw three old men with long white beards sitting in her front yard. She said, ‘I don't think I know you, but you must be hungry. Please come in and have something to eat.’ ‘We do not go into a House together,’ they replied. ‘Why is that?’ she asked.
One of the old men explained, ‘His name is Wealth,’ he said pointing to one of his friends, ‘a(chǎn)nd he is Success, and I am Love.’ Then he added, ‘Now go in and discuss with your husband which one of us you want in your home.’
The woman went in and told her husband what the old man said. Her husband was excited. ‘How nice!’ he said. ‘Since is the case, let us invite Wealth. Let him come and fill our home with wealth!’ His wife disagreed. ‘My dear, why don't we invite Success?’ Their daughter was listening from the other corner of the house. She jumped in with her own suggestion, ‘Wouldn't it be better to invite Love? Our home will then be full of love.’ The husband said to his wife, ‘Go out and invite Love to be our guest.’
The woman went out and asked the three old men, ‘Which one of you is Love? Please come in and be our guest.’ Love got up and started walking towards the house. The other two also got up and followed him, the lady asked Wealth and Success, ‘I only invited Love, ­why are you coming in?’
The old men replied together, ‘If you had invited Wealth or Success, the other two of us would have stayed out, but since you invited Love, wherever he goes, we go with him. Wherever there is Love, there is also Wealth and Success!’

Most of us lead a busy life. Driven by the “urgent(緊急的)”, we forget to enjoy life. We think, “If I reach my goal, then I’ll be happy”,  or “If I can get a better job, then I’ll enjoy life.” But why not enjoy life right now?
Firstly, take time to notice and appreciate the beauty in your own surroundings; you don’t need to travel far to find beauty. “There is a great big world of wonder and beauty around us!” Andrea Brodersen explains. “Look for the beauty of the sunrise and of a friend’s smile that brightens your day. Open your eyes to see the beauty you might not normally see. Doing so helps to cheer you up.”
Secondly, taking time to experience some simple pleasures also can bring joy to your heart and ease your stress. Take me for example. I delight in simple things like my favorite tea drink, a bubble bath or family photos. One common            is finding things that make you laugh. Make time to laugh every day.
Thirdly, don’t take your family and friends for granted. Rich, rewarding relationships add greatly to the enjoyment of life. When you think of someone, why not call, e-mail or write them? A short e-mail or phone call can make a world of difference to someone. As Wayne Lawton explains, “Invest time in relationships. Remove the attitude, what’s in it for me? Happiness is found in putting other’s interests, desires and concerns ahead of our own whenever possible. Selfishness is a dead-end street.” So please treasure relationship.
小題1: What is the main idea of this passage? (no more than 10 words)
