Asking for directions is the first thing we need to do when we get to a different country. Knowing how to ask for help can make our life much easier! Here are some tips for you.

Use greetings and polite expressions: Starting the conversation with a friendly greeting is a must. If you want to get a great answer, begin by saying “hello” first. And finish with a “thank you” and “have a nice day”.

Examples: Excuse me, could you help me?/ Hello! May I ask for some help? / I need to get to the CN tower.

Build your vocabulary: You should know the basic vocabulary that can be used when getting directions. Try to remember places like High Park, Queen Street, and words like traffic lights, bank, block, etc.

Examples: It’s about two blocks away from here. /Go along the street until you reach the traffic lights.

Learn the most commonly used prepositions and adverbs: Some important prepositions to remember are between, next to, and straight ahead. And the adverbs nears, nearer, and nearest are very useful when you need to find somewhere fast.

Examples: The zoo is straight ahead. / It’s between a bank and a post office.

Try to know some important landmarks: Every city in the world has its own landmarks. You can cut down on search time if you know what the important landmarks are.

Examples: It is next to the CN Tower! Go past the Aquarium and then turn left.

Sometimes our body does things we don't ask it to do. Sneezing(打喷嚏),coughing, blinking(眨眼睛)and even yawning(打哈欠)are examples of involuntary movements or reflex actions(反射动作). What makes our body do these things?

These involuntary actions are a response(反应)to a stimulus(刺激). When we do these things, our body is trying to protect itself. If an irritant(刺激物)such as pollen(花粉)from plants gets into our nose or nasal passages(鼻腔通道),our body sneezes to get it out. If we breathe in dust, our body coughs to remove it from our lungs(肺)or windpipe. We blink in order to keep our eyes clean and moist(湿润)and to prevent dust and other things from staying on them. A yawn is our body's way of making us put more oxygen into our bloodstream.

　　　　　　　 . These involuntary movements happen because our brain is giving out signals. There is a system of nerves(神经)called the central nervous system, that covers our entire body: from the brain, down the spinal cord(脊髓)inside our spinal column (the bones that do down our back,to the tips of our fingers and toes. When our body parts sense certain things, like a mosquito蚊子)bite, a message is sent to our brain. Then the brain sends a message back to itch(发痒).

Without these reflex actions, we would not live very long.

1.What is the passage mainly about?

A.We would not live long without movements. B.Why our body does involuntary movements.

C.We sneeze to get out an irritant such as pollen. D.How our brain is giving out signals to our nerves.

2.If dust comes into our eyes, we will________ to protect our body.

A.cough B.sneeze C.blink D.yawn

3.Which of the following sentences can be put at the beginning of Paragraph 3?

A.What tells our body to take care of us the way it does?

B.Don't you think it is interesting for our body to do so?

C.What can we do when involuntary movements happen?

D.How can we avoid stimulus to protect our own body?

Have you ever been ill? When you are ill, you must be unhappy because your body becomes hot, and there are pains all over your body. You don’t want to work, and you stay in bed, feeling very sad.

What makes us ill? It is germs(细菌). Germs are everywhere. They are very small and you can’t find them with your eyes, but you can see them with a mi­croscope(显微镜). They are very very small and there could be hundreds of them on a very small thing.

Germs are always found in dirty water. When we look at dirty water under the microscope, we shall see them in it. So your father and mother will not let you drink dirty water.
