  In the 1800's…(十九世纪)

  请注意年代的表达方法,以上的年代也可以表达为in the 1600s; in the 1720s; in the 1800s.如果我们要表达“在十七世纪初(中、末)期”,则可以说in the early(mid, late) 1600's/1600s.

  9. Diamonds became very popular with the kings and queens of Europe.

  become / be popular with / among是一个常用词组,意思是“受…欢迎”,请看下面的句子:

  1) These Chinese handicrafts are very popular with foreign friends. (这些中国工艺品很受外国朋友的喜爱。)

  2) I have run out of ink. (我的墨水用完了。)

  12. These diamonds were probably carried from where they were formed to India by great sheets of moving ice that covered parts of the earth 20,000 years ago.

  where they were formed是where引出的名词性从句,作介词from的宾语。请看下面的句子:

  1) He didn't say anything about where the accident took place. (他对事故在哪儿发生的只字未提。)

  2) She hasn't made up her mind as to where she should go for the holiday. (她还没有决定到哪儿去度假。)

  13. It flows over boards thickly coated with grease.

  在本句中的定语从句thickly coated with greases前面省略了which/that are.coat一般做名词用,意思是“外套”或“(动物的)皮毛”。在本句中coat作动词用,意思是“在…上涂(包)着”,如:

  1) These pills are coated with sugar. (这些药丸外面包着糖衣。)

  2) Don't jump on the bush piles, they are ice-coated and slippery. (不要在灌木堆上跳,上面盖着冰,很滑。)

  14. Since diamonds stick to grease, they are left behind by the rocks and mud which flow down the tables.

  Stick在本句中的意思是“粘住”。Stick to也可以表示“坚持,遵守”的意思。请看下面的句子:

  1) I'm sure father hasn't read the book because several pages are stuck together. (我敢肯定父亲没有看过那本书,因为有几页还粘在一起。)

  2) It's important for nurses to stick to the rules. (对护士来说,遵守规定是很重要的。)

  3) Stick to your post and make sure everything is ok. (坚守你的岗位,确保一切正常。)

  leave behind在本句中的意思是“留下”,这个词组还可以表示“忘带;把…丢在后面”。例如:

  1) Take care not to leave anything behind. (小心别丢下任何东西。)

  2) Look forward to the bright future and leave all your worries and fears behind. (期盼光明的未来,把所有的担心和恐惧抛在身后。)
