2. Reading & Interacting  (for two classes)
a. New words and phrases of Reading & Interacting;
b. Give a brief introduction of the general idea of the story told in the text;
  This article sets out to win us over to the idea that more resources should be given to deep sea research. The writer could have simply given us a dry lecture on the benefits. Instead he engages our interest by wrapping up his argument in a series of contrasts. Difficulty and success are held in skilful tension throughout. Having started by quoting an authority on how little we know about the deep sea in general, he moves on to regret how li
ttle we know about the giant squid in particular. It comes as a pleasant surprise when the negative tone set by these details of our ignorance is suddenly shattered in Paragraph Three with the account of the filming of the giant squid. Having shown what can be done with modern resources the author then returns to his theme of how much more needs to be done. The success was, after all, “but a drop…in the ocean.” But he then switches back once again to a more positive note, illustrating what can be achieved with the story of his sinking of the whale. Even in his simile of the watch, a similar pattern is present. As he points out, while understanding the ocean depths is much like understanding the mechanism of a watch, unlike a watch the ocean depths are far more difficult to open up.
