If you’ve spent any amount of time boating, fishing, or bird-watching at lakes and rivers, you have most likely seen fishes jumping out of the water. I have seen it many times. Certainly, fishes will exit water in desperate attempts to escape enemies. Dolphins take advantage of the behavior, forming a circle and catching the frightened fishes in midair. But just as we may run fast from fun or from fear, different emotions might motivate fishes to jump.
Mobula rays(蝸鲼)aren’t motivated by fear when they throw their impressive bodies—up to a seventeen-foot wingspan (the distance from the end of one wing to the end of the other) and a ton in weight—skyward in leap(跳跃)of up to ten feet. They do it in schools(鱼群)of hundreds. They usually land on their bellies, but sometimes they land on their backs. Some scientists think it might be a way of removing parasites(寄生虫). But I think that the rays are enjoying themselves.
In the clear waters of Florida’s Chassahowitzka National Wildlife Refuge, I watched several schools of fifty or more mullets(鲻鱼)moving in beautiful formation. Their well-built bodies were most evident when they leaped from the water. Most of the time I saw one or two leaps by a fish, but one made a series of seven. They usually land on their sides. Each jump was about a foot clear of the water and two to three feet in length.
Nobody knows for sure why the fish leaps. One idea is that they do it to take in oxygen. The idea is supported by the fact that mullets leap more when the water is lower in oxygen, but is challenged by the likelihood that jumping costs more energy than is gained by breathing air. It is hard to imagine they will feel any fresher when back in water.
Might these fishes also be leaping for fun? There is some new evidence. Gordon M. Burghardt recently published accounts of a dozen types of fishes leaping repeatedly, sometimes over floating objects—sticks, plants, sunning turtle—for no clear reason other than entertainment.
1.What can we say about the dolphins in Paragraph 1?
A.They have great escaping skills. B.They are easily frightened.
C.They are very clever. D.They love jumping.
2.What do the ray and the mullet have in common when jumping?
A.Both do it in groups. B.Both land on their bellies.
C.Both jump many feet out of water. D.Both make leaps one after the other.
3.How does the author feel about the idea mentioned in Paragraph 4?
A.It is valuable. B.It is interesting.
C.It is imaginative. D.It is questionable.
4.Which may be the reason for fish leaps according to the author?
A.To remove parasites. B.To amuse themselves.
C.To take in more oxygen. D.To express positive emotions.

Heading overseas on a business trip or just for pleasure any time soon?If so,have you thought about what you are going to do about communication?You may need to arrange cab service or get directions to an attraction,not to mention you want to stay in touch with the folks back home.
Hope you aren’t counting_on your personal cell phone.Industry experts estimate that most American cell phones won’t work overseas due to compatibility (兼容性) issues.And even if yours did work,the roaming (漫游) charges would be too high.
So what are your choices?You could rent a phone with a local number in the country you’re traveling to,but that wouldn’t do you much good if you’re constantly on the go.A more costeffective way would be to rent a satellite phone from a company like Global Cellular Rental.
The process is amazingly fast and simple.All you have to do is to log onto the company’s website,www.globalcellularrental.com,and place an order.The site will show you the countries you will be traveling to and ask you how long you will need the phone.The company then ships a cell phone directly to you anywhere in the world.The phone arrives with complete instructions.
The traveler also learns his overseas phone number well in advance,enabling him to inform all vital contacts of the number before he ever steps on a plane.
Roaming rates are usually 80 percent less than those charged by American service providers.Calls back to the US can be discounted 40 percent or more.The rentals cost is just $5 per day,and discount packages are available for longterm rentals of two months or more.
This cell phone solution is becoming so popular that Global Cellular Rental actually has relationships with hotel chains around the world to keep phones in stock for hotel guests.And for those whose journey really takes them off the beaten track,the company can also rent satellite phones to them.These phones work anywhere in the world as long as you are outside.

Do you enjoy reading? Do you read newspapers or magazines? Chances are, if you do any of these activities, your preschool child is on his way to becoming a reader.
The process of learning to read is complex, and one of the most important things to know is that parents can help their children learn to read.As children have conversations with adults, they hear both new and familiar words and their vocabulary grows.
There are many opportunities for adults and children to talk together, such as when riding in the car or in a bus, doing housework like fixing dinner,or bathing and getting ready for bed. A major part of conversation is listening. When children talk, adults listen and respond.Then children listen and respond,and so the flow of conversation happens.
Have you watched your preschool child pretend to read to his younger sisters or brothers? Have you read his favorite story over and over?These experiences tell children that reading is fun.And when things are fun and they are repeated, your child will see letters. He begins to connect them to familiar words, especially the letters that make up his name.A natural next step for him to take is to write the letters.
When children see parents make a grocery list,they want to use a pencil and paper to make their own list. To encourage these beginning writing activities, have pencils, markers, crayons and scrap paper within your children's reach.
The more children get connected with talking,listening, reading and writing, the easier it is for them to become active readers. While you as a parent have a big influence on these early behaviors, it is important to remember that opportunities for literacy experiences happen when you and your child share in the basic routines(日常生活) of everyday life.
1.The third paragraph tell us that parents can talk with their children________.
A.during daily routines
B.only in quiet places
C.in their spare time
D.when they are eager to talk
2.During the process of learning to read,children may ________.
A.copy the action of the adults
B.prefer to talk with those of their own age
C.show no interest in reading at all
D.waste a lot of paper and other materials
3.When do children want to learn to write?
A.When their parents ask them to do so.
B.When they believe they can write well.
C.When they know what they want to know.
D.When they can connect letters with familiar words.
4.The passage is written to________.
A.talk about parents' influence on their children's behavior
B.encourage parents to set a good example to their children
C.advise parents to make reading a part of their children's daily life
D.make parents believe in the importance of early reading

“If you run for more than five minutes at any time, you might need a pair of running shoes,” advises Stephen Pribut, a US sports medicine expert. Running shoes are highly technical footwear. They provide stability(牢固)while bearing up to three times the wearer’s body weight. But it’s not easy to find the right pair. Finding the right running shoes is something of an art, or a science and a feel.
The science part begins with the shape of the arch(弓)of your foot, which anyone can find out at home with this quick experiment: Put your foot in water and place it on a piece of brown paper. If you see a “C” shape on the paper when you remove your foot, you have a rare high arch. If the shape looks more like a rectangle, that means you have flat feet. See something in between? That’s a normal arch.
Conveniently for shoppers, shoe companies nowadays divide their shoes in three categories: neutral(for high arches), stability(for normal or low arches) and motion control(for flat arches). So you will know which type suits you.
At this point, most people would just grab an appealing shoe and try it on. But professionals would do a few quality-control tests. First, you bend the shoe toe to heel to see where it bends. If it’s not at the forefoot---where the foot actually bends, be afraid. Then you grip both ends and twist in opposite directions. If you can twist it like a towel, it means there’s zero support. Finally, you squeeze(挤)the heel in both directions. A stable heel won’t cave in.
Now you need to check the mold(模子)that shapes the inside of the shoe: whether it’s wide or narrow in the mid-foot, how it sits on the heel and how roomy the toe box is.
It’s wise to hold off until the afternoon to make the shoe purchase, to allow for any swelling(肿胀) that your feet do throughout the day. Toes also decide sizing choice. The rule is you need a finger’s width from your longest toe (whether that’s your big one or not) to the end of the shoe.
1.What is the main idea of this passage?
A.Advantages of wearing running shoes fitting you.
B.Ways to get to know about the shape of the arch of your foot.
C.Advice on how to choose the right pair of running shoes.
D.Best time to buy a pair of running shoes.
2.If the arch of your foot looks like a “C” shape, you have _________.
A.a normal arch B.a high arch C.a flat arch D.a low arch
3..The underlined phrase “cave in” most probably means ______.
A.bend B.stretch C.shake D.crash
4..Why is the late afternoon the ideal time to go shopping for shoes?
A.We are likely to be more patient in the afternoon.
B.Feet usually become large late in the day.
C.The toes become longer late in the day.
D.The arch of our feet will be in best shape in the afternoon.

What do you usually do when you have some free time? Do you take part in any form of hobby? If your answer is no, then you should think twice. Experiencing some type of interest or hobby might be the ideal way to develop your brain and improve your creative thinking.
Here is a common problem that many older people have. They have spent such a great deal of time raising their family that once their children are grown and left home, they all of a sudden start to experience their age. Quite often, it is not their age that is the concern. It is the fact that they are unexpectedly offered more time on their hands.
When you put in too much time not doing anything, this can affect your brain. This is just where the expression “If you don’t use it, you lose it” definitely is the truth. Your mind needs working out much like any other muscle in your body. This is why getting a hobby matters. It offers you something to do and is a perfect way to meet new people.
Enjoying a hobby is also a perfect way to improve creative thinking at any age. Even young children can profit from taking a new hobby. For retired people, enjoying a hobby which they can find entertainment in with their grandchildren will help keep them active and feeling young at heart.
Several hobbies that are terrific for both your mind and you body include yoga, biking, swimming and golf. If you aren’t fond of sports, even taking a walk regularly is a wonderful way to keep active. It helps you to appreciate fresh scenery and it has been suggested that the colors green and blue help make you more creative.
As you can see above, you can get pretty much from taking a hobby. With so many choices waiting for you, begin your journey right away!
1.What can be implied about many older people from Paragraph 2?
A. They lock creative thinking.
B. They should develop their brain.
C. They concern about their age.
D. They used to have little free time.
2.Why does getting a hobby matter according to the text?
A. It strengthens one’s brain.
B. It helps build up one’s muscle.
C. It enables one to make friends.
D. It improves one’s living conditions.
3.What does the underlined word “terrific” in Paragraph 5 probably mean?
A. Specific. B. Disgusting.
C. Wonderful. D. Fundamental.
4.Which of the following can be the best title for the text?
A. Trying different hobbies B. Spending your free time
C. Experiencing your hobby now D. Feeling young at heart
