There are about fifteen hundred languages in the world. But only a few of them are very important. English is one of them. Many, many people use it, not only in England and the USA, but also in other parts of the world.

About 200,000,000 people speak it as their own language. It is difficult to say how many people are learning it as a foreign language. Many millions of people are trying to do so. Is it easy or difficult to learn English? Different people may have different answers. Have you ever noticed ads(广告) of this kind in the newspapers or magazines? “Learn English in six weeks, or give your money back…” “Easy and funny…” “Our records and tapes help you master English in a month”. Of course, it never happens quite like that.

The only language that seems easy to learn is the mother tongue. We should remember that we all learned our own language well when we were children. If we could learn English in the same way, it would not seem so difficult. Think of what a small child does. He listens to what people say. He tries what he hears.

So it is hard to say that learning English is easy. We must do a lot of practice. And practice needs great efforts and takes much time. Good teachers, record, tapes, books, and dictionaries will be helpful, but they cannot do the student’s work for him.

You move every day. Every time you sit down, walk, ride a bike, or eat your food, you are moving. You e1. move while you are sitting in a chair. What gets you moving, keeps you moving, and helps you to move the way you want to move?

One force that helps you move is gravity. Gravity pulls you toward Earth. Why? Earth is bigger and h2. than you are, so you’re pulled by Earth’s gravity. How does that help you? When you take a step, gravity pulls on your foot. That pulling helps you put your foot down. Then, you can move your o3. foot. Do you like to play baseball? Gravity makes the baseball fall after it is h4.. Then, as gravity pulls the ball toward the ground, and can catch the ball.

Friction also helps you move. Friction happens when two o5. rub against each other. How does friction help you move? When you walk, friction keeps your feet from slipping. When you hold a pencil, friction helps keep it in your h6.. and friction makes the brakes on your bike work. too.

Inertia also helps you. Inertia is a sort of rule: it tells us two things; Things that are in movement will remain in movement until something stops them; and things that are at rest will stay at rest unless something moves them. When you ride your bike, it will keep going until you stop it, and when you sit down to read, you will stay where you are until you are r7. to move.

Next time you move, think about gravity, friction and inertia. All of them help to get you where you want to go.

① gravity n. 重力 ② friction n. 摩擦力 ③ inertia n. 惯性
