First of all, it's a myth that no two snowflakes(雪花)are the same.　 In 1988, a scientist found two exact same snow crystals(晶体)that had both formed in a snow storm in Wisconsin, USA.

Since then scientists have come to learn that snowflakes can only form into 35 different shapes. Although scientists are also not sure why exactly the various shapes of snowflake form, they have confirmed(确定)eight main shapes, with each of these eight shapes having several different variations(变化).

Second biggest myth, snow isn't white. It's actually colorless. Snow is made up of very small pieces of ice, and ice is translucent(半透明的), which means that light does not pass through it easily, but rather it gets reflected(反射).

When light hits a snowflake, it gets reflected back from the snowflake's many surfaces, often bouncing(弹跳)between these surfaces, and because of this that light is reflected back to our eyes as the color white. This is why, when we have a close look at a snowflake, it always looks clear, yet in reality appears as white.

1.What does the underlined word "myth" probably mean in the passage?

A.Something that is not true. B.Something that is amazing.

C.Something that is interesting. D.Something that is not good.

2.Which of the following statements is TRUE according to the passage?

A.Light can easily pass through ice.

B.A scientist found two different snow crystals.

C.When we have a close look at a snowflake, it looks clear.

D.Scientists are sure about the reasons why various shapes of snowflake form.

3.This passage is probably from　 ________ .

A.a weather report B.a science magazine C.a science fiction D.a travel guide

It’s good to make mistakes, and here is why.

First of all, mistakes are a clear sign that you are trying new things. It’s always good to try new things because when you are trying new things you are growing. If you never try anything new, how can you improve? How can you make yourself stronger? The simple answer is “You can’t.” Look around you. With very few exceptions(例外), either everything you see in your world or every single detail of every single thing is the result of someone trying something new．

Another good thing about mistakes is this: When you are making mistakes, you are learning．Consider this: Edison failed 10,000 times before he perfected the light bulb. When asked how it felt to fail that many times, he said that he hadn’t failed 10,000 times, but rather had learned 10,000 things that didn’t work．

Finally, when you make a mistake you are much closer to success. Why? Because when all is said and done, you will have tried some numbers of things before you succeed．Every time you make a mistake, you eliminate one of those things and are one step closer. But this all doesn’t mean that you should go ahead without considering the consequences(后果) of a mistake. However, when you try something new you have to be willing to set some reasonable limits（限度） so that in the event that it doesn’t work out the way you want it to, you will be in a normal place to try again．

We all have limited time and money so don’t blow them all on one problem. Realize that it probably won’t be perfect the first time and deal with these resources(资源) properly so you can learn, make corrections, and try it again．If you accept and use your mistakes in this way ,you can make great progress in your business and your career．

There is an old saying that goes, “If you’re not making mistakes, you’re not trying hard enough.”

So go ahead and make mistakes. And learn. And grow. And succeed．

1.From the second paragraph, we can know that _______．

A. mistakes are unnecessary for development　　

B. we are afraid of trying new thing

C. it’s common for people to make mistakes　　　

D. mistakes are better than not trying

2.The underlined word “eliminate” means _______．

A. study     　　 B. remove     　　　　 C. accept　　　　　　 D. solve

3.According to the article, one thing you should pay attention to about making mistakes is_____．

A. not making the same mistakes

B. accepting the punishment willingly

C. taking consequences into consideration

D. trying things out one by one

4.What would the writer probably suggest we say to ourselves when we make a mistake?

A. Never mind, I can always try again．

B. I’d better stay out of trouble．

C. Ok! Now I can learn something．

D. Look at this mess. Anyone would be sad．

Fear and its companion pain are two of the most useful things that men and animals possess if they are properly used. If fire did not hurt when it burnt, children would play it until their hands were burnt away. Similarly, if pain existed but fear did not, a child would burn itself again and again, because fear would not warn the child to keep away from the fire that had burnt him or her before. A really fearless soldier—and some do exist—is not a good soldier because he is soon killed; and a dead soldier is of no use to his army. Fear and pain are therefore two guards without which men and animals might soon die out.

In our first sentence we suggested that fear ought to be properly used. If, for example, you never go out of your house because of the danger of being knocked down and killed in the street by a car, you are letting fear rule you too much. Even in your house you are not absolutely safe: a plane may crash on your house, or ants may eat away some of the wood in your roof , and they later may fall on you , or you may get cancer!

The important thing is not to let fear rule you , but instead to use fear as your servant and guide. Fear will warn you of dangers; then you have to decide what action to take.

In many cases, you can take quick and successful action to avoid the danger. For example, you see a car coming straight towards you; fear warns you, you jump out of the way, and all is OK.

In some cases, however, you decide that there is nothing that you can do to avoid the danger. For example, you cannot prevent a plane from crashing into your house, and you may not want to go and live in a desert where there are no plants. In this case , fear has given you its warning; you have examined it and decided on your course of action, so fear of this particular danger is no longer of any use to you , and you have to try to overcome it.

1.Children would play with fire until their hands were burnt away if ________.

A.they were given no warning beforehand B.they didn't have any sense of pain at all

C.they had never burnt themselves D.they felt afraid of the fire

2.A really fearless soldier ________.

A.is of a little use to his army B.is not afraid of battles at all

C.is nothing but a dead soldier D.is easy to get killed in a battle

3.People sometimes succeed in timely avoiding dangers because ________.

A.they are warned of the danger and take quick action

B.they are quick both in mind and in action

C.they are calm in face of danger

D.they have gained much experience

4.It is implied but not stated that ________.

A.fear is always something helpful

B.too much fear is harmful

C.fear should be used as a servant and guide

D.fear is something strange and particular

I learnt two things. You don’t have to know______; and if you don’t know how to spell something, just get the dictionary out. Both are very useful lessons!

In school, you also learn to deal with life in general. Little mistakes can seem to be very serious. Wear the wrong clothes and it seems that everyone is laughing at you. Get too close to a boy too fast and everyone talks about you. You want to go into a hole and die! But the truth is that life goes on. You might feel that what you did "wrong" will never ever be forgotten. However, if you can be brave and keep on, you will find that whatever happened will pass and you will start to enjoy life again.

We bad a class called Guidance and in it we learnt about making good decisions in life. I found it pretty boring and didn't pay much attention. One day the teacher made us guess which appliance(家电)we should buy first once we had our own homes. The answer was a fridge. I learnt that it was true once I had my own place. The first day I bought some chicken meat. By dinner time it smelled and I couldn't even eat it! My housemate and I started saving to buy a fridge right away.
