9.Sometimes the greatest things are invented by mistake.The greatest mistake of all time could be those delicious snacks in your corner 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(烘培)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 eleven-year-old
boy.In 1905,Frank sat outside on a winter evening,mixing up a big jug(罐子)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 5cents 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!
任务一 请根据短文,猜测划线单词(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.
1.Take out a chocolate bar andbreak it into little pieces
2.Then addthe pieces into her cookies dough
3.Finally bake it.
任务三 请列举文中与 (2)Popsicles 同义的另外两个表述.Epperson Icicles/the frozen pop/powered soda pop/the mixture in the jug frozen with the mixing stick stuck in the middle.
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.Sometimes the greatest things are invented by mistake.

分析 本文介绍了巧克力饼干和冰棍的发明都是偶然的,失误的发明的.有时候,最伟大的东西是的错误发明的.所以,下次你把你的汉堡包放进冰淇淋里或者把煮熟的土豆放进鸡汤里时,别担心!世界上最美味的食物就是这样发明的!

解答 任务一 A词义猜测题.根据后半句:在微波炉里,可知此处是:巧克力会融化.故答案为:A.
任务二 (1)break it into little pieces细节理解题. 根据she took out a chocolate bar and broke it into little pieces可知第一步是她拿出一块巧克力,并把它分成小块
          (2)the pieces into her cookies dough细节理解题.根据She added the pieces to her cookie dough(面团)and baked(烘培)it.可知她把小块加入面包团.故答案为:the pieces into her cookies dough.
任务三 Epperson Icicles/the frozen pop/powered soda pop/the mixture in the jug frozen with the mixing stick stuck in the middle.原句意为:他后来把名字改为冰棍.故答案为:Epperson Icicles/the frozen pop/powered soda pop/the mixture in the jug frozen with the mixing stick stuck in the middle.
任务四主旨大意题.根据文章内容可知本文介绍了巧克力饼干和冰棍的发明都是偶然的,所以可以用 Sometimes the greatest things are invented by mistake.这个句子概括本文的大意.

点评 做题时首先要仔细阅读短文,掌握大意,然后结合具体的题目,找出相关信息,就可以确定正确答案.

17.Traffic rules help to keep order on the road.They also help to keep people safe.Traffic accidents killed more than 104,000people in China last year.As we all know there are more cars than before.So drivers and pedestrians (行人) must work together to make the roads much safer.
The pedestrian(行人) has as many rules to follow as the drivers.You should walk on the sidewalk(人行道) on the road.Always look carefully before you walk across the street.
If you often ride a bike,don't ride in the middle of the road or run through red traffic lights.When you ride a bike with a friend,don't look around or talk.
Drivers should slow down at the traffic lights.And the driver and passengers must always wear seat belts (安全带).Without seat belts,they may be badly hurt in a sudden accident.
You must be careful if you have to travel in a bus.Get on or get off a bus only after it stops.When it is full,don't try to get inside,or you may fall off.
Traffic rules are road safety rules.Please remember the famous saying"Thinking about others".
