    Planes have changed the world in the last hundred years. But this great change began with two ordinary people.

Orville and Wilbur Wright were two brothers who had a bicycle shop in Ohio, the USA. They were good at making bicycles, but planes were their real interest.

At that time, people knew how to build and fly gliders (planes without engines), but nobody could build a plane with an engine and fly it. The plane builders had two main problems: they could not make the wings strong enough, and the planes always crashed(坠毁) when they tried to take off.

The Wright brothers read about these problems in a newspaper, and they decided to look for answers. They made small model planes in the bicycle shop and they built a wind tunnel to test the models. They also built real gliders. Finally, they built a plane with an engine, which they called The Flyer.

On December 17th 1903, Orville and Wilbur pulled The Flyer onto a fat sandy beach. The plane weighed 275 kilograms and had a petrol engine. The day was very cold, and there was a wind of about 30 kilometres per hour. The brothers tossed(投掷) a coin to see who should fly first. Orville won. He climbed onto the plane and started the engine.

The Flyer began to move into the wind, Wilbur ran along beside the plane, And then the plane took offIt flew for only 12 seconds, but someone took a photograph, and the plane flew into the history books.

1.People have used planes with engines for more than _______ years.

A.50 B.100 C.150 D.200

2.What was one of the glider builders’ main problems before 1903?

A.None of them was good at making and selling bicycles.

B.Their planes could take off and fly for only 30 minutes.

C.They could not afford to buy an engine for their planes.

D.They could not make enough strong wings for their planes.

3.Why did the Wright brothers make models?

A.They made models to test their ideas.

B.They hoped to sell them for money.

C.They had nothing to do and did that for fun.

D.They weren't interested in making real planes.

4.How was the weather on the day of The Flyer’s flight?

A.Rainy. B.Warm. C.Windy. D.Hot.

5.Which of the following is TRUE according to the passage?

A.The Wright brothers owned a model plane shop in the USA before 1903.

B.When The Flyer began its first flight in 1903, it weighed 275 kilograms.

C.Orville and Wilbur both wanted to fly the plane first and Wilbur won at last.

D.The plane The Flyer succeeded in taking off and flew for only 12 minutes.

    An idiom is a phrase that we can’t understand from the meaning of each word. For example, if an American boy asks his mom what’s for dinner tomorrow, she may say “I’ll play it by ear”, that means she doesn't have plans for dinner and she will decide later.

“Play it by ear” used to mean playing music without using the sheet music(乐谱), but now people often use it when they’re not talking about music!

There are many idioms in English. If you learn to use them, your English will be much more vivid(生动的)and colourful.

Have you ever heard the idiom “He bought the farm”? It means he died. Do you know how it became popular? It was first used during World War I. When a soldier died, the government gave his family enough money to buy a farm.

In the early 1930s, people in the U.S. often did not know when or where their next meal was coming from. So as soon as they got something in their hand that could be eaten, it would go into their mouth. That was how people began to use the idiom “living hand to mouth” to mean “living a poor life”.

And don’t be angry if your English friend says this to you, “Break a leg in your game!" In fact, he is wishing you good luck! Hundreds of years ago, people believed in sprites. Sprites enjoyed causing trouble. If the sprites heard you ask for something, they would make the opposite take place. Tell someone to “break a leg” and the sprites would make something good take place.

Aren’t English idioms interesting? And break a leg in your next football match!

    What’s the best thing to eat on a hot summer day? Many people would say ice-cream. Yes, eating ice-cream with some fruit on top is a great way to cool down. But think before you eat. If your body is hot from playing sports, it's not the best time to eat ice-cream.

When your body is hot, a lot of ice-cream may give your stomach some problems, and you could get diarrhea(腹泻). You can eat some ice-cream after you’ve cooled down a bit and had some tea. Just try not to eat too much all at once!

After dinner is another time people shouldn’t eat or drink anything cold. Drink something hot after you eat, and your stomach will digest your food better. If you love fruit, summer is a great time for you. Go to the market and pick out the best fruit of the season. If you want to stay cool, oranges, bananas, pears and watermelons can help. Also, try to eat more ginger()and gram(绿豆). They will help you stay cool and healthy.

In summer, bacteria(细菌) grow very fast and make your food go bad quickly. Try hard to keep yourself and your home clean in summer. Always eat clean, fresh food. When you feel like eating a cold dish, put vinegar()in it to kill bacteria. If you can’t finish your food and want to eat it again next day, make sure you heat it enough to kill the bacteria in it. And when you put food in the fridge, make sure to keep the cooked food away from the uncooked food.
