托福阅读:大海啸Megatsunami

2016-05-02 16:36:00来源:网络

  Words:

  Contend v. 声称

  Wedge-shaped 楔形的

  Madagascar 马达加斯加

  Landslide n. 山崩

  Spark v. 闪现,激励

  Chevron n. 山形袖章

  Sentence:

  The idea is that either a huge impact, or a large landslide from a volcano on the island Réunion, sparked the tsunami that created the chevrons.

  这个观点是巨大的撞击或是R岛上火山山崩引起了产生山形袖章的海啸。

  Now, Abbott and an international team of researchers have presented further evidence to back up their theory: a geo-chemical fingerprint from Madagascar that firms up the date for the massive tsunami. The study of ancient megatsunamis has been controversial, though; not only is it hard to detect evidence that literally washes away, but also to establish proof of a tsunami's cause—such as an impact or earthquake—occurring at the same time.

  Words:

  Back up 支持

  Fingerprint n. 指纹

  Massive adj. 巨大的

  Wash away 冲走

  Sentence:

  The study of ancient megatsunamis has been controversial, though; not only is it hard to detect evidence that literally washes away, but also to establish proof of a tsunami's cause—such as an impact or earthquake—occurring at the same time.

  可是古代大海啸的研究是有争议性的,不仅仅是因为很难去探测那些实在地 被冲走的证据,还因为确定海啸的原因-比如说是撞击或是地震-是发生在同一时间的。
