Question

【題目】 Fill in the blanks with proper words （在短文的空格內(nèi)填入適當(dāng)?shù)脑~，使其內(nèi)容通順，每空格限填一詞，首字母已給）

You move every day. Every time you sit down, walk, ride a bike, or eat your food, you are moving. You e【1】 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 h【2】 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 o【3】 foot. Do you like to play baseball? Gravity makes the baseball fall after it is h【4】. Then, as gravity pulls the ball toward the ground, and can catch the ball.

Friction also helps you move. Friction happens when two o【5】 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 h【6】. 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 r【7】 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. 慣性

【解析】

文章大意： 有一種力量可以幫助你移動，那就是重力。地球比你大，比你重，所以你被地球的引力所牽引。重力使棒球在被擊中后下落。然后，當(dāng)重力把球拉向地面，就能接住球。摩擦力也能幫助你移動。當(dāng)兩個物體相互摩擦?xí)r就會產(chǎn)生摩擦力。當(dāng)你走路時，摩擦力使你的腳不滑倒。當(dāng)你拿著鉛筆時，摩擦力有助于把它留在手里。慣性是一種規(guī)律：它告訴我們兩件事：在運(yùn)動中的事物將保持運(yùn)動直到有東西阻止它們；在靜止中的事物將保持靜止，除非有東西移動它們。下次你移動的時候，想想重力，摩擦力和慣性。所有這些都能幫你找到你想去的地方。
