一、任务型阅读。

Sometimes the greatest things are invented by mistake. The greatest mistake of all time could be those delicious snacks in your comer drugstore.

One day, a woman was making chocolate cookies. When she ran out of chocolate powder (粉), she took out a chocolate bar and broke it into little pieces. She added the pieces to her cookie dough (面团) and baked (烘烤) it. She thought that the chocolate would (1) melt in the oven and make chocolate cookies. Far from melting, the pieces of chocolate stayed hard. When she took them out of the oven, she had chocolate chip cookies!

Another accidental invention was made by Frank Epperson, an elevenyearold boy. In 1905, Frank sat outside on a winter evening, mixing up a big jug (罐) of powdered soda pop. Frank accidentally left the jug out during the night. When he went outside the next morning, he found the mixture in the jug frozen (冻僵) with the mixing stick stuck in the middle. Frank pulled out the frozen pop and tasted it. It was delicious! Frank started

selling Epperson Icicles for 5 cents each. He later changed the name to (2) Popsicles.

So, the next time you drop your hamburger into your ice cream or your cooked potatoes into your chicken soup, don't worry! Some of the most delicious foods in the world were invented that way! 根据短文内容，完成下列任务。

任务一 请根据短文，猜测画线单词(1)melt的意思。将答案的字母代号填写在横线上。 A．change into water B．change into ice

任务二 请根据短文内容，完成chocolate chip cookies的制作过程。

任务三 请列举文中与(2)Popsicles同义的另外两个表述。

任务四 请从文章中找出能够概括本文主旨大意的一个句子。 二、阅读理解。

People are always afraid of making mistakes. But sometimes it's not bad to make mistakes, and here is why.

At first, 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 new things, how can you improve? How can you create? The simple answer is, “You can't.” look around you, everything you see is the result of someone trying new things.

Another good thing about mistakes is this: when you are making mistakes, you are learning. Consider this: Edison failed 10，000 times before he invented the light bulb. When he was asked

5

how he felt to fail that many times, he said that he hadn't failed 10，000 times, but rather had learnt 10，000 things that didn't work.

Finally, when you make a mistake, you are that much closer to success. Why? Because you have said what you should say, and you have done what you should do. Every time you make a mistake, you are closer to success. But it doesn't mean that you can make mistakes without thinking. Instead, when you try new things you have to think them over, so that you can keep away form some unnecessary mistakes.

We shouldn't spend all our time and money on the only one way, but use the correctly. Because our time and money are limited(有限的).

There is an old saying, “If you are not making mistakes, you are not trying hard enough.” So go bravely and make mistakes. And learn. And grow. And succeed. 6．If you make a mistake, that means ． A．you're careful B．you're kind C. you're growing

7．If you never try new things, you can't . A．improve B．create C. A and B

8．After Edison failed 10，000 times, he . A．gave up

B．invented the light bulb C．invented the computer

9．When you make a mistake, you are closer to . A．time B．money C．success 10．What's the main idea of this passage？ A．Never make mistakes.

B．You can make mistakes without thinking. C．Sometimes it's good to make mistakes.
