I'm sure you all know how important recycling is. Recycling is when you take old things and turn them into new things. It sounds like magic. But it's actually very scientific.

The first thing you have to do is to collect items (物品) that can be recycled. Only certain materials can be recycled. These include things made of paper, metal, glass and plastic.

Earthquakes usually come without warning. What should you do if this happens to you? An earthquake is dangerous, but there are still things you can do to protect yourself.

Stay calm as the earth begins to shake. Your chances of survival in an earthquake go up if you can keep calm. Staying calm is not easy, but it can save your life.

If you are inside when the earthquake starts, get under a table or a bed. You need to have something strong around you to protect you from falling objects. Do not stand near walls and windows and stay out of the kitchen. The kitchen is dangerous because of many glass objects.

If you are outside, get to an open area as fast as you can. Stay away from buildings and trees. If you are in a car, pull over to a place where there are no trees or tall buildings and stay in the car. If you are close to the sea, try to get as far away from the water as possible. Earthquakes can cause huge waves(浪) that can really harm the people nearby.

When the earthquake is over, there is still plenty of danger. For example, gas fire often comes with an earthquake. If you see a fire, quickly move outdoors to an open area.

Always remember to hope for the best but prepare for the worst.

“Listen!” Mr. Lee said seriously at the beginning of his first class, “I will put a lie into each of my classes. Your job is to try and catch me in the Lie of the Day.”

That was really a clever way to fix our attention on the dry and boring subject — geography. Then in the following weeks, we didn't let off every single word of what he was saying in class and challenged（質(zhì)疑）his lectures. When his class ended with nobody seeing through the lie, Mr. Lee would say, “Ah ha! Each of you has a lie in your notes. Discuss among yourselves what it might be, and I will tell you at the end of this term.”

Mr. Lee’s special style of teaching worked. All of us reviewed and discussed about our notes actively.

One Monday at the end of the term, Mr. Lee listened carefully to what we were questioning for almost ten minutes. Then he finally said, “Do you still remember the first lesson how I said that every lecture has a lie?”

Confused, we said yes.

"Well, that was a real big lie. In fact, all the lectures I’ve given before are completely true. But I am glad you worked so hard. Move on ...”

Hearing this, all eyes in the classroom went wide.

While my knowledge of geography has been forgotten over time, the lessons have stayed with me. "Experts" can be wrong and say things that sound right, so build a habit of evaluating （評(píng)估）new information and check it against things you already accept as a fact.

1.We can know that Mr. Lee was ________.

A.wise B.serious C.boring D.confusing

2.In Mr. Lee’s class, ________.

A.he always told lies B.the students always questioned him

C.everyone had to write down all of his words D.it was difficult for the students to see through the lie

3.The underlined sentence in the passage means________.

A.the students opened their eyes B.Mr. Lee opened the students’eyes

C.the students got shocked and amazed D.the students had a look at the classroom

4.From the passage, we can infer that________.

A.Mr. Lee was an expert

B.it’s easy to forget the knowledge of geography

C.Mr. Lee succeeded drawing the students’ attention

D.the students would never check what the teachers said again

5.The best title of the passage could be ________.

A.A Real Lie B.Learn to Question

C.A Special Teaching Style D.The First Geography Lesson
