Ⅰ.七选五

Have you ever had a wonderful idea and thought it would make a great invention, but didn't know what to do next？__1__ They will help you make your dreams come true and become a famous inventor.

The first thing that you should do is do some research on the Internet to see if anyone else has

invented it. If not, you should search through the U. S. Patent (专利) information to see if a patent was ever created for your type of invention. __2__ The easiest thing to do is working with an agency(代理机构) that can help you to make your dreams a reality.

It can help you present your ideas and get your product to the right companies. One agency that is very reputable (声誉好的) is “Lambert in Minnesota”. __3__

If they think your product is marketable (有销路的), they will help you to get it to the right company. Call the agency and make an appointment. You will want to bring in a model of your invention and a complete description of your ideas. __4__

Then when you meet with them, you can present it and they will tell you how marketable it is. If they decide to help you, they will work to present it to different companies and help you to go to the next step. Once your invention has been sold to a large company, get ready to get the benefits of becoming the next great inventor. __5__ But the benefits are worth the wait.

A．It may take a year or two.

B．If not, go to the next step.

C．You will find something new on the Internet.

D．You will be the next inventor.

E．Write down exactly about your invention.

F．Here are some steps that you can take.

G．They offer free advice for good ideas.

【语篇解读】本文是一篇说明文。很多人有好点子，但是不知道如何把好点子变成伟大的发明，文章对此提出了几点建议。

1．F根据本段第一句可知很多人有很棒的想法，认为自己的想法会成为伟大的发明，但是不知道该如何去做。横线句要把上下文串联起来，F项“Here are some steps that you can take(下面是你可以采取的步骤)．”承上启下。

2．B本段告诉我们首先要对自己的发明项目进行研究，查看是否已经有人发明出类似的物品。如果没有，查一下相关的专利情况。如果没有类似的专利被申请，那么你就可以继续做下一步工作。故B项“If not, go to the next step.”符合上下文语境。

3．G根据前句“One agency that is very reputable is ‘Lambert in Minnesota’．”可知“Lambert in Minnesota”是一家声誉非常好的代理机构。本句应该介绍这一机构的良好服务，故G项“They offer free advice for good ideas(他们会为好点子提供免费建议)．”与之对应。

4．E根据前句可知你和代理机构联系好了以后，你要带着模型以及对这个好点子的叙述。最好是把你的想法确切地写下来，然后与对方交流。故E项“Write down exactly about y our invention.”与上下文语境一致。

5．A此处表示：如果你的发明被某一公司购买，那么你只要等待发明给你带来的好处即可。虽然等待的时间可能会比较长，但这样的等待是值得的。故A项“It may take a year or two.”符合上下文语境。

Ⅱ.读后续写
