Here’s an amazing way to get a hard-boiled egg into a bottle, even though the mouth of the boiled is smaller than the egg! What’s more, you don’t even need to touch the egg to get it to go in!
For this experiment you will need:
·a hard-boiled egg
·a glass bottle with a mouth just slightly smaller than the egg (a fruit-drink bottle works well)
·a 8-cm by 8-cm(3-inch by 3-inch)piece of newspaper
·a match
Remove the shell from the egg. Set the egg on the mouth of the bottle to see that the egg does not fit through the mouth.
Light the paper. Remove the egg from the mouth of the bottle and drop the burning paper into the bottle. Before the fire goes out, set the egg back onto the mouth of the bottle. Within a few seconds the egg will squeeze(挤) through the mouth and into the bottle.
As it entered the bottle, the egg may have broken into pieces. This happens when the diameter(直径) of the egg is more than about 0.5 cm(about 3/16 inch) larger than the diameter of the bottle’s opening.
Why does the egg slide into the bottle, even though no one is pushing it? Because the pressure of the air is pushing it. Before the burning paper is put into the bottle, the pressure of the air inside is the same as outside. The burning paper, however, heats the air inside. This causes the air inside to expand. When the egg is placed on top of the bottle, it seals(封住) the bottle. When the fire goes out, the air inside cools. As it cools, the air contracts(紧缩), and the pressure of the air inside becomes less than the pressure outside. Then, the higher outside pressure pushes the egg into the bottle!
The best title of this passage can be      .

A.An interesting story B.The pressure of the air
C.Egg in a bottle D.Egg, bottle and match

What don’t you need in this experiment?

A.Eggs. B.Water. C.Bottles. D.Paper.

Why will the egg break into pieces while entering the bottle?

A.Because of the burning paper.
B.Because the diameter of the egg is too larger than that of the bottles opening.
C.Because it is cool inside the bottle.
D.Because the pressure of the air inside is larger.

What is the most important to get the egg into a bottle?

A.A match. B.A fruit-drink bottle. C.The pressure of the air. D.The burning paper.

Millions of people around the world cook their food over smoky fire every day.It is often difficult to find wood for the fire .People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun.
Solar cooker, or ovens,have been used for centuries.A Swiss scientist made the first solar oven in seventeen sixty-seven. Today ,people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms.
There are three kinds of solar ovens.The first is a box cooker, It is designed with a special wall that shines or reflects sunlight into the box .Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amonts of food.
The second kind of solar oven is a panel cooker. It includes several flat walls.or panels.that directly reflect the sun’s light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much.In Kenya ,for example ,panel cookers are being manufactured for just two dollars.
The third kind of solar oven is a parabolic cooker.It has rounded walls that aim sunlight directly into the bottom of the oven .Food cooks quickly in parabolic ovens .However, these cookers are hard to make.They must be re-aimed often to follow the sun .Parabolic cookers can also cause burns and eye injuries if they are not used correctly.
You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at two hundred thirty-two degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things.

C.solar cookers cost less than other cookers
D.Swiss often use solar cookers while cooking
