Module 6 判断题 - Exercise 19

1. Clayton Christensen, a Harvard Business School Professor, describes how disruptive innovations—simpler, cheaper and more convenient products that seriously upset the status quo—often herald the rapid downfall of thriving, long-standing businesses.

2. The ultimate outcome of any one innovation may still be unpredictable, but the process from which it emerges is not.

3. If T-rex was a top predator, especially considering how big it is, you’d expect it to be extremely rare, much rarer than the little dromaeosaurs they prey on, and yet they are everywhere, they are a dime a dozen.

4. For eight years Michael had endured a condition called ankylosing spondylitis, a chronic autoimmune disease of the skeleton. No one knows what triggers it. In the worst cases, the spine may fuse, leaving the patient forever stooped and couldn’t even walk; he every morning, and during bad flare-ups, it was so horrible I couldn’t. “My back hurt” he says. But days after the scorpion sting, the pain went away, and now, two years later, he remains essentially pain-free and off most of his medications. As a doctor himself, Michael is cautious about overstating the role of the scorpion’s venom in his remission. Still, he says, “if my pain came back, I’d let that scorpion sting me again.”

5. We used different types of book to teach letters to 30-month-old children. One was a simple old-fashioned alphabet book with each letter accompanied by an appropriate picture. The other was a 3-D version. The children using the traditional book subsequently recognised more letters than those using the 3-D book.
