If we find a bird nest (巢), we will have a good place of watching and knowing about birds. Birds sit on eggs and take care of their babies from April to June. Because the baby birds are too young to leave the nest, parents often go to look for food and come back in several minutes. So it is good to watch birds. When we watch birds, we'd better hide ourselves in a close place to the nest, and it's better to use binoculars (双筒望远镜).

But how do we make a bird nest? A good bird nest must be very fine, strong, thick and comfortable. If you want to make one, please follow these:

a) Each nest must have six boards (木板) for its cover and floor, for its left and right sides, and for its front and back sides. Don't make the boards too slippery (滑的).

b) Dig a small hole in the front of the nest as a "door". The "door" is big enough so birds can fly in or out easily.

c) Make sure the rainwater can't go into the nest.

d) One piece of the board should be easy to open.  

e) Don't forget to colour the nest.

Have you ever heard an echo of your voice?

An echo is a reflected(反射)sound. Stand in a very large, empty hall with nothing on the walls. Then shout. The sounds you make will hit the walls and come back to you. The walls reflect the sounds. These reflected sounds are called “echoes”.

We can use reflected sound to make sound travel farther. Hold a watch about fifty centimeters from your ear. You cannot hear it. The sound of the watch travels a short way in all directions. It does not travel as far as your ear. You can make it travel to your ear by using a roll of cardboard(纸板筒).

Make the roll of cardboard about fifty centimeters long. Put one end over your ear and hold the watch at the other. Now you can hear the watch because the sound has not gone in all directions. It is reflected down the roll to your ear.

A megaphone(喇叭筒)works in the same way. It makes sound travel farther. It reflects the sound into a beam which can travel a long way. In the ship, the sailor uses the megaphone to make his voice travel. Without the megaphone, his voice cannot travel far.

We use reflected sound in many ways. We use it to measure the depth of the sea, for example. Among the animals, bats and whales use reflected sound to tell them where they are and what things are near them.

1.What is called “echo”?

A．Very loud voices.

D．shout in the open air

3.Which is the right order of hearing our echo in a very large, empty hall?

a. We hear the reflected sound

b. The sound returns to us

c. The sound hits the walls

d. We make a sound

A．c, b, a, d          B．c, a, b, d           C．d, c, b, a           D．d, b, c, a

4.From the text we learn that __________ .

A．reflected sound is useful only to blind people

B．people haven’t made use of reflected sound yet

C．bats use reflected sound to fly and get food

D．whales don’t use reflected sound as they live in the sea

5.If you haven’t got a megaphone, ____ will help you to make your voice travel farther.

A．a long piece of wood                     B．a roll of cardboard

C．a thin thread                           D．a long piece of silk

 

 

 

Camping in your backyard is full of fun, whatever your age. It's great for keeping us relaxed. It offers chances to check the night sky and to be noisier than usual. It lets us have friends over to stay who might not fit inside the house! Follow these instructions and you'll have a night you’ll never forget!

Put up your tent.

    Depending on the number of family members and guests, you may need more than one tent. Tell your friends to bring their tents if needed. Follow the instructions or check out the articles on how to put up a tent on the Internet.

Prepare your bedding.

     You'II want your guests to be able to relax in comfort. Put something soft to lie on on the floor: A blow-up air mattress or thick comforters may work well. Fill the tent with soft toys and  blankets (毯子). Have lightweight sleeping bags or cotton blankets. They are especially important if you live where the night temperatures drop greatly.

 Prepare a seating area.

     If you have a picnic table, that would work best. If not, set up a few chairs and a small table to set out drinks and food. A simple choice is to lay out a blanket in the sun,  so that your friends can eat and talk. Be sure the grass isn 't wet!

Make memories.

    Plan some activities. You're camping in the backyard, so it's time to make the most of being outdoors.

    Have a camera nearby to take silly photos of you, your family members, and your friends. Take one large group shot with everyone smiling and laughing. Be sure to make copies for everyone!

5.What is the passage mainly about?

 

There is not enough oil in the world now. As time goes by ,it becomes less and less ,so what are we going to do when it runs out? Perhaps we will go back to use horses ,carriages and bicycles .
In the Second World War ,some people didn＇t use gas made from petroleum （石油）in their cars .They made gas from wood and plants instead . The cars didn＇t go fast ,but they ran ,so this was better than nothing. However, in the future, we can＇t cut down all our trees to make gas; we need our trees for other things, too.
Besides different types of gas, we can also use electricity(电)to run our cars but first we must make the electricity ！Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big ,strong rivers and they can use the power of water to turn turbines(涡轮机) and make electricity more easily and cheaply.
We are also able to get power from the ocean tides. We put turbines into the mouth of the river .Then the tide comes in ,the water turns the turbines and then it goes out ,it turns them again.
Which of these ways will be used to run our cars in the future?
【小题1】When might people have to go back to using horses and carriages?
