多任务混合阅读
You may think that inventions are far away from your everyday life. But in fact almost everyone can invent. It’s just that they do not recognize that their ideas could be the start of an invention.
Once inventors see their ideas have some practical value they don’t let them slip away.
For example, the inventor of the dishwasher American Josephine Cochrane loved to give dinner parties. But she found it took long to wash her dishes by hand and too many of them broke. She decided that a machine could do the job faster and with fewer mistakes. So in 1886 she set out to make one for herself.
Cochrane’s most wonderful inventions are created to solve the problem. So the first and most important step is to find the problem.
You can start by looking at what is wrong with the things you are using now. You can ask grandparents or neighbors if they remember ever saying: “I wish someone would invent something for ...” Or you can look at people in different areas — such as on the street or at school. Then you might notice situations or things in need of improvement. Remember to record your ideas and work. This will help you develop your invention and protect (保护) it when it is completed.
The next step is to think about possible solutions. An invention is a new way of solving a problem. So think of many varied (各种各样的) and unusual ways. You can often come up with a solution to a problem by looking at it from a different angle (角度) or thinking about it in a new way.
And the hardest part of inventing even for a lot of inventors is finding a problem and coming up with a solution. Once you have an idea you can always get help to build your invention.
This problem-solving technique can also work in your everyday lives. So why not try it in your studies, in your relationship with others or even in the way you look at the world
21．完成句子。
Josephine Cochrane found it took long to wash her dishes .
22．用英语表达文中画线单词one所指代的内容：
_____________________________________________________
23．找出并写下第四段的主题句。
_________________________________________
24．What is the hardest part of inventing

25．将文中画线句子翻译成汉语。

Unit 6 Section B 1a-1e分层作业答案与详解
一、根据句意填空。
1．Doctors say lemons are better for us even though they are （sour）than most fruits.
【答案】sourer
【详解】句意：医生说柠檬对我们更好，尽管它们比大多数水果都酸。根据空后than可知，此空应填sour“酸的”的比较级形式，故填sourer。
2．The soup you made yesterday was too s . We were all thirsty after drinking it.
【答案】salty
【详解】句意：昨天你做的汤太咸了，我们在喝了它之后都是口渴的。设空处用在系动词后面作表语，应填入一个形容词；根据We were all thirsty after drinking it.结合首字母提示，可知此处表达的是“咸的”，故填salty。
3．It is said that potato chips were invented by m .
【答案】(m)istake
【详解】句意：据说薯片是偶然发明的。固定短语by mistake“无意地，偶然地”，故填(m)istake。
4．The （顾客）were angry because the potatoes were not thin.
【答案】customers
【详解】句意：因为土豆不细，顾客非常生气。由语境和所给的汉语可知，顾客：customer；由谓语were是复数判断，此处的主语用复数形式，故填customers。
5．I really don’t know with (谁) I should discuss the problem.
【答案】whom
【详解】句意：我真的不知道该和谁讨论这个问题。介词with后应用代词宾格whom“谁”。故填whom。

【答案】
21．by hand 22．A dishwasher/A machine.
23．So the first and most important step is to find the problem.
24．It is finding a problem and coming up with a solution.
25．从一个不同的角度看问题或用一种新的方式考虑问题，你通常就可以想出它的解决方案。
【导语】
本文介绍了人人都有可能发明东西，并且介绍了发明的步骤，其中最难的部分是想出问题，然后找到解决方法。
【详解】
21．根据“But she found it took long to wash her dishes by hand and too many of them broke. ”可知Josephine Cochrane认为用手洗碗花费的时间太长，故填by hand。
22．根据“For example, the inventor of the dishwasher American Josephine Cochrane loved to give dinner parties. ... She decided that a machine could do the job faster and with fewer mistakes. So in 1886 she set out to make one for herself.”可知她认为机器可以更快地完成这项工作，而且错误更少。所以在1886年，她开始为自己做一个。故此处one代指的是洗碗机，故填A dishwasher/A machine.
23．根据“Cochrane’s most wonderful inventions are created to solve the problem. So the first and most important step is to find the problem.”可知第四段的主题句是“So the first and most important step is to find the problem.”，讲第一步及最重要的一部要做什么。故填So the first and most important step is to find the problem.
24．根据“And the hardest part of inventing even for a lot of inventors is finding a problem and coming up with a solution.”可知发明最困难的部分是想出问题，然后找到解决方法。故填It is finding a problem and coming up with a solution.
25．come up with“想出”， a solution to a problem“一个问题的解决方案”。by doing sth“通过做某事”，look at“看”； from a different side“从不同的角度”，故填“从一个不同的角度看问题或用一种新的方式考虑问题，你通常就可以想出它的解决方案。”
