【题目】As the little boy saw the stranger, he turned ______into the narrow street where he lived.

A.quietB.paleC.clearlyD.quickly

【答案】D

【解析】

句意:当小男孩看到陌生人时,他迅速拐进了他住的狭窄街道。

考查副词。quiet安静的;pale苍白的;clearly清晰地;quickly迅速地。横线上所填词是来修饰动词turned的,故需要一个副词来修饰它,根据前句As the little boy saw the stranger当看到陌生人时。可推测出,小男孩应该是迅速地拐进了他住的狭窄街道。故选D

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.

gravity n. 重力 friction n. 摩擦力 inertia n. 惯性
