only 修饰状语,至于句首,主句的语序需要 倒装。此句如改成正常语序应是:You can say that you are truly an inventor only after you have had that recognition. 又如: Only by working hard can we pass the exams.

某些否定词至于句首,表示强调时也会引起 倒装。如: never, seldom, hardly, neither, nor, not, only, little 等。 如课文中令一句: Nor will you receive a patent until a search has been made to find out that your product really is different from everyone else’s.

novel 在此处是形容词,意思是 “新的;新 颖的;新奇的”。其名词形式是novelty。 He is a person who always has novel ideas. 他经常会有新奇的想法。

1. He believed that one should always be curious and his most famous saying was: ”Leave the beaten track occasionally and dive into the woods. Every time you do you will be certain to find something that you have never seen before. Follow it up, explore all around it, and before you know it, you will have something worth thinking about to occupy your mind. All really big discoveries are the result of thought.” 他认为一个人应当具有好奇心,他最著名的一句话 是:“偶尔离开平路去寻求困境。当你这么做的时 候,你一定会发现你从未见过的东西。跟踪下去, 不断探索,不知不觉中,你就会发现某种值得思考 的东西占据着你的头脑。所有真正伟大的发现都是 思考的结果。”

beaten track 踏平的路;一贯的路;惯例。如: We followed a well-beaten track through the forest. 我们沿着一条人们他出来的路穿过森林。 dive (vt)

to go headfirst into water 潜入;跳水。例如:
He dived into the river and rescued the drowning child. 他跳到水中,救起那快要溺死的小孩。

to move quickly in a specified direction 扑去;冲去。 例如: when the rain started, we dived into a café 雨下了起 . 来,我们立即跑进一家小餐馆。

woods 原指“森林”,在这里有“险境,困境”的 意思。out of the woods 表示“脱离麻烦或困难”。 如:
The situation is improving, but we are not out of the woods yet. 情况正在改善,但我们还没有摆脱困境。

2. Although he is most often associated with the invention of the telephone, he was indeed a continuing searcher after practical solutions to improve the quality of everybody’s life.
虽然人们常把他和发明电话联系起来,但是他的确 是一名永不停息的探索家,不断寻求着改善人们生 活质量的途径。 associate with 把… 和…联系起来;和…来往。如: In our minds the Spring Festival is associated with happy family reunions. 在我们心中,春节是和愉快 的家庭团聚联系在一起的。 Her parents didn’t like her associating with net friends. 她的父母不喜欢她和网友来往。

句中的continuing是动词-ing形式,在这里作定语 用。如: This is a very pressing problem. 这是意见紧急的 事情。

out of order 坏了;有毛病。如:
