  8. She married to Pierre Curie who was also a bright scientist in 1895.

  9. Another scientist Henri Becquerel • He found that uranium gave off rays. • Marie decided to study this area and named the rays “radioactive”

  10. The discovery of Polonium. • In 1898 she discovered the first of these radioactive minerals, which she named “Polonium” in honor of her motherland—Poland.

  11. They worked together. • They devoted all their hours to working in their laboratory on their research.

  12. Her thoughts:“Life is not easy for any of us, we must work, and above all, we must believe in ourselves. We must believe that each one of us is able to do something well, and that ,when we discover what this something is, we must work hard at it until we succeed. ”

  38. Language points: • 1. admit vt. 接纳,许可…..进入 • My sister was lucky to be admitted to Beijing University. • The windows are small and don’t admit enough light and air. • 2. succeed in +n./doing sth.在…方面取得成功 • I am sure they will succeed in discovering the strange plant.

  39. (1) At that time women were not admitted to universities in Poland, so Marie was determined to go to Paris and study there. 当时在波兰妇女是不允许进大学的,因此,玛丽决定去巴黎学习。 admit vt.接纳,许可(人/物)进入(allow sb. / sth. to enter)。 例如: 1. 我们学校每年只收二百名男女学生。 2.我的姐姐很幸运,被北京大学录取了。 3.窗户都很小,不能让足够的光线和空气进入室内。

  41. (2) She succeeded in taking a first-class degree in physics two years after arriving in Paris.到巴黎两年以后,她顺利地取得了一级物理学位。 ① succeed vi. 成功,获得成功。succeed 后面常跟 in 引起的短语,构成succeed in sth. / doing sth. 的结构,表示“在......方面取得是成功”的意思。succeed in doing sth. 常可以有灵活的译法(见本句译文)。例如: 1.

  44. ② a first-class degree大学学位分三级。第一级是最高级,第三级是最低级。 (3) Not long before another scientist had found that uranium gave off rays ...不久以前,另外有位科学家发现过铀元素放出射线的现象.....。 短语动词give off作“散发”、 “放出”(to send out sth., especially a liquid, gas or smell)解。例如: 1.Boiling water gives off steam. 沸腾的水散发出蒸气。 2. The gas gave off an unpleasant smell

  45. 3. give off…散发, 放出 give out …发出(声、光、热、信号),发表,公布,耗尽 Burning leaves give off thick smoke. After the long walk , his legs gave out and couldn’t go any farther. 4.

  46. (4) There was a certain mineral which was even more radioactive than uranium. 有一种矿物,它具有放射性甚至比铀还强。 形容词比较级 more radioactive 前用了副词 even, 以加强比较的语气和程度。在比较级前可以加的这类词或词组还有 much, far, still, a lot等。例如: • This problem is much more difficult than that one. • The next day they got to a far bigger forest (than the first one) • Let's work harder to win still greater success.

  47. (5) In 1898 she discovered the first of these new radioactive minerals, which she named "polonium" in honour of her motherland - Poland ... 1898年,她现了这些新放射性矿物中的第一种。为向她的祖国-波兰表示敬意,她把这种矿物取名为“钋”......。 介词短语 in honour of sb. / sth.意思是“为了纪念/尊敬某人/某事”。例如: 为了纪念他们的英雄事迹,建立了一座纪念碑。 A monument was built in honour of their heroic deeds.

  48. b. in honor/honour of ------showing respect to 为纪念…… e.g. They called the boy Sam in honour of his father who died before his birth.

  49. (6) We must work, and above all we must believe in ourselves.(=We must work, and first of all we must trust ourselves. ) 我们必须工作,尤其重要的是,我们必须对自己有信心。 ① 句中的 above all是插入语,意思是“首要的是”(of first importance) 或“尤其是”(most especially)。例如: Never waste anything, but above all never waste time. 任何东西都不可浪费,尤其不可浪费时间。

  50. ② believe in (= have faith in, trust) 信赖,信任;而 believe的意思则是“相信某人的话”。 试比较: A: Do you believe him? 你相信他的话吗? B: Yes, I do. But still he isn't a man to believe in. 我相信他的话,不过他还是一个不能信赖的人。 To live, one must have something to believe in. 为了生活,人们总得有某种信奉的东西。
