　　The underlined word remedy in Paragraph 1 is closest in meaning to________.

　　A．avoid B．acceptC．improve

　　D．consider

　　解析：词义猜测题。由画线词所在的句子的语境可知，成功者的秘诀在于不是把注意力集中在谁该受到责备而是集中在怎样改善糟糕的境况。此处的动词remedy意为：改进，改正，纠正；所以improve“改善，改进”符合题意。

　　The term “multitasking” originally referred to a computer’s ability to carry out several tasks at one time. For many people, multitasking has become a way of life and even a key to success. In fact, some excellent mental aerobic exercises(大脑训练)involve engaging the brain in two or more challenging activities at a time. Although checking email while talking on a phone and reading the newspaper may be second nature for some people, many times multitasking can make us less productive, rather than more. And studies show that too much multitasking can lead to increased stress, anxiety and memory loss.

　　In order to multitask, the brain uses an area known as the prefrontal cortex(前额叶脑皮层). Brain scans of volunteers performing multiple tasks together show that as they shift from task to task, this front part of the brain actually takes a moment of rest between tasks. You may have experienced a prefrontal cortex “moment of rest” yourself if you’ve ever dialed(拨电话)a phone number and suddenly forgotten who you called when the line is answered. What probably occurred is that between the dialing and the answering, your mind shifted to another thought or task, and then took that “moment” to come back. Research has also shown that for many volunteers, job efficiency(效率)declines while multitasking, as compared to when they perform only one task at a time.
