Most animals on land are known to us, but many living things underwater are not. Now let’s get to know some of them.
Sea cucumber
Sea cucumber are strange animals living at the bottom of the sea. They wear brown or pale green coats with many sticks up. When summer comes, they stay deep to sleep because they are afraid of heat. And when it is autumn, they move to shallow (浅的) water and get their food.
Pike
The pike is a kind of freshwater fish. They are good swimmers and like swimming near boats, waiting to be fed. They have sharp teeth to catch fishes. When they are young, they live in groups. However, when they grow up, they prefer to live alone.
Cuttlefish
A cuttlefish can swim quite fast, so it is also called rocket (火箭) fish. It has eight arms and two feelers on its head, just around its mouth. It ejects ink (喷墨) when it is in danger. Its meat is delicious, and it is often the first choice for many people.
Octopus
An octopus has long arms, with which to catch food and protect itself. When it is sleeping, one or two of its arms are still on duty, keeping moving. Once it feels something dangerous, it can wake up at once to take action.

Frogs are animals that can live both in water and on land. There are more than 5,000 kinds of frogs on the earth. The earliest known frogs lived about 190 million years ago and the frogs today still look the same. Here are some fun things that you might not know about frogs. Enjoy!
The Biggest and the Smallest Frogs
Some frogs can be very big. The biggest kind of frog is the Goliath Frog in West Africa. Its body can be nearly 30cm long, about the size of a large cat. The Gold Frog and the Poison Frog are the smallest frogs in the world. They are less than 1cm long. Though the Poison Frog is very small, it is not weak at all. It is dangerous. Any animal that eats it will die very soon.
The Best Jumpers
Frogs are very good at jumping. They developed jumping legs so that they would not be eaten by other large animals. Using their big strong legs, more frogs can jump over 20 times their own length. It is like a person jumping over about 30,48. The Australian Rocket Frog can even jump over 2m, which is 50 times its body length(5.5cm). That might be the reason why frogs are called the best jumpers on the earth.
The Cryogenic Animal
Some frogs like the Common Wood Frog have a special ability to live in very cold places. When the temperature goes down, they become ice frogs. 2/3of their body water freezes. Their hearts stop, and their breathing stops too. You may think they are dead, but in fact they are not. Maybe we humans can learn the way that the frogs do for medical purpose.
1.The earliest frogs lived about ________ million years ago.
A. 20 B. 30 C. 50 D. 190
2.The Gold Frog is one of the ________ frogs on the earth.
A. smallest B. biggest C. strongest D. weakest
3.________ can jump over 2m.
A. The Goliath Frog B. The Common Wood Frog
C. The Poison Frog D. The Australian Rocket Frog
4.What will happen to a Common Wood Frog at very low temperature?
A.It will die very soon. B. It will be an ice frog.
B.It will become dangerous. D. It will become very small

Robots come in many shapes and sizes. But most have one thing in common. They are built to help people. Lately engineers have been developing new kinds of humanoid robots. These high-tech machines are designed to lend a hand everywhere from hotels to disaster areas.
"Robots help people by making their lives easier, safer, and more fun," says engineer Omar Abdelwahed.
Since November, a robot named pepper has been on the job at the Mandarin Oriental hotel in Las Vegas, Nevada. When guests have questions or need directions, they can ask Pepper. They can also use the robot's touch screen to find the information they need. Pepper is able to talk with guests and entertain them with stories too. It can even tell what kind of mood they are in.
"Pepper provides our guests with information in an exciting and new way," says hotel manager Donald Bowman.
For a kid, being in the hospital can be boring and even scary. But a small robot called NAO is helping to make hospital stays easier. It was designed to keep people company.
A Tennessee doctor named Phil Parker bought a NAO robot three years ago. He programmed it to talk to and play with young patients. He brings it to hospitals to help sick kids. When kids get medical tests, NAO explains what is going on. The robots also reads to kids and plays games with them like rock, paper, scissors.
"The robot gets many kids to smile for the first time since they've been in the hospital," Parker says.
Other robots are being developed to help in places where it's hard or risky for people to go. For example, disaster areas can be full of rubble and other dangers. Engineers in Japan are building a robot called E2-DR to go into those areas and search for people who are hurt.
1.In Mandarin Oriental hotel, guests can____________.
A. only get information simply by touching the robot's screen
B. feel entertained with the stories about Pepper.
C. experience an exciting and new way to get the information

Nearly all our food comes from the soil. Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter (粪) from animals also falls on it.
All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals’ waste is the best food for the soil, but chemical fertilizers (化肥) are also very useful. The same crop (庄稼) should not be grown in the same place every year; it’s better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good.
1.What would happen first without plants?
A.People would have more crops. B.Animals would die.
C.There would be more food. D.There would be less soil.
2.What does the writer tell us in the first paragraph (段落)?
A.Leaves, plants, grass and waste live on each other.
B.There would be no animals without meat.
C.There would be no plants without animals.
D.People, animals, plants and soil live on each other.
3.Which is the best food for soil in the field?
A.Chemical fertilizers B.Plants and grass. C.Animals’ waste. D.Different crops.
4.Why do we often grow a different crop in the same place every year?
A.Because we can keep the soil rich this way.
B.Because we don’t have enough land.
C.Because we want to have a different food.
D.Because we do this as a habit.
5.What is the best title for the passage?
A.Soil and Waste B.Plants and Animals C.Food and Waste D.Soil and Food

Monkeys surprise us
Humans are the most intelligent animals on Earth. 1.But sometimes, our way of thinking can become an obstacle (障碍).
Julia Watzek, a graduate student in psychology at Georgia State University, US, recently did some research on the problem-solving abilities of both monkeys and humans.2.They intended to test their ability to change their strategies(策略) in the game. In this game, each player was shown four squares on a computer screen: one striped square, one spotted square and two blank squares. While being trained to play the game, they learned that clicking the stripedsquare and then the spotted square would cause a blue triangle to pop up in one of the blank squares. Clicking on the blue triangle would give them a reward. 3. But partway through the game, the researchers introduced a shortcut (捷径). Suddenly, the blue triangle started appearing at the start of gameplay, alongside the striped and spotted squares.4.Remarkably, about 70 percent of the monkeys figured out this shortcut immediately. 5. Only 1 out of 56 human players figured out the shortcut right away.
Watzek’s conclusion was that humans tend to get “stuck in their ways” when it comes to strategic thinking. Things such as standardized testing and formal schooling might cause humans to use the same strategy over and over, even when it doesn’t work very well.
A.Monkeys never did better than human.
B.She and her team had them play a simple game.
C.The spotted square didn’t appear at all till the end.
D.Humans, on the other hand, were slow to figure it out.
E.We have mental abilities that other animals don’t have.
F.If a player clicked on the blue triangle, they’d receive their reward right away.
G.Human players would hear a “woop!” sound and monkey players would receive a snack.
