解析试题分析:考察情态动词用法。本句中前句中的were说明本句叙述的是过去的事情,故使用“情态动词+have done”表示对过去的虚拟或者推测。排除AC项。Might have done也许做了某事;must have done一定做了某事;句意:你想爬到那里真是太愚蠢了。你也许会伤到自己的。故B正确。
考点:考察情态动词用法
点评:本题是高考必考考点,一定要牢记句型意思。must have done过去肯定做了某事。should have done 本应该做而实际未做。can’t have done 过去不可能做了某事;shouldn’t have done 本不应该做而实际做了。 need have done 本有必要做某事;needn’t have done 本没有必要做某事;注意没有 mustn’t have done的形式。
Have you ever intended to be fully absorbed in your work but found yourself distracted by e-mail, the Internet and other things throughout the day? According to the survey made by a famous university in the USA, most people have the experience.
"People often lose their concentration when they are bored, of course, but also when they are engaged in challenging tasks," says Peter Bregman, the head of the survey. "They sometimes have a feeling to escape from what's difficult or boring, so they jump out," he says. The part of the brain devoted to attention is connected to the brain's emotional center. Any strong emotion —quarrels with colleagues, problems at home —can interrupt our attention. Studies over the last decade have shown that too much work to do at a time can easily lead to distraction.
Refocusing is hard for many people. Robert Epstein suggests the following, "Stop and listen to some soft music for a few minutes. Find a good friend or a teacher and say out your matter on your mind. Go for a short walk or take a deep breath, where you breathe in deeply, count to five slowly, hold it and breathe out very slowly." This can "blow out all the tension and the unwanted in your mind to restore your focus."
Take more control by structuring your time and becoming more aware of your behaviors. "Setting the phone alarm to go off every hour is my way of creating awareness," Mr. Bregman says. "You have to inform yourself that you've lost focus in order to do something about it." Starting the day with a to-do list is also important, such as when to eat, when to go to the gym or take a walk. But if it's overly ambitious, you will put yourself in a state of anxiety, which makes it hard for the brain to concentrate. "Choosing three or four things as your priority for the day allows your brain to settle down and focus," he says.
