  大家有没有一个经验,就是做听力时候,一句句听都听得懂,但是连在一起听,就不明白了。其实,有时候听者把精力过多的放在单词、短语、一个个句子上,而割裂了句间逻辑,以及意群,所以,得到的信息是碎片,而不是完整的意群。那么应该怎么做呢?

托福听力精听练习的正确打开姿势

  第一步练习

  针对听力基础较薄弱的学生,可以以段落挖空的形式做听写。

  方法:

  如TPO1-L2 Geology:听一段音频,在空白处填空。

  Uranium-Lead Dating allowed them to go about it in an entirely different way. What they did was: they looked at the grains of Zircon in the sandstone. Zircon is a material that contains ①_________ Uranium, which makes it very useful for dating purposes. Zircon ②_________ as molten magma, the hot ③____from volcanoes. This magma then ④__________. And when Zircon crystallizes, theUranium inside it begins to change into Lead. So if you measure the amount ofLead in the Zircon grain, you can ⑤__________ when the grain was formed. Afterthat, you can ⑥_________ the age of Zircon from different mountain ranges. Once you do that, you can compare the age of the Zircon in the sandstone in your ⑦__________to the age of the Zircon in the mountains. If the age of the Zircon ⑧__________the age of one of the mountain ranges, then it means the sandstone actuallyused to be part of that particular mountain range. Is everybody with me onthat? Good. So, in this case, Uranium-Lead Dating was used to establish that half of the sandstone in the samples was formed at the same time the granite in the Appalachian Mountains was formed. So because of this, this new way of doing Uranium-Lead Dating, we’ve been able to determine that one of our major ⑨_________about the Grand Canyon was wrong.

  答案:

  ① radioactive ②starts off ③lava ④crystallizes⑤figure out

  ⑥ determine ⑦sample ⑧matches ⑨assumptions
