题目内容
【题目】Walter offered us a lift when he was leaving the office, but our work ______, we refused his offer.
A. not finished B. had not been finished
C. not finishing D. not having finished
【答案】A
【解析】
考查独立主格结构。句意：当Walter离开办公室的时候，主动让我们搭便车，但是因为工作没有完成，我们拒绝了他的帮助。连词but引导两个并列句中Walter offered us a lift when he was leaving the office 和we refused his offer. 说明“our work __”不能是完整的句子；名词短语our work与动词finish构成被动关系，而CD两项都表示主动。B项与our work构成了一个完整的句子our work had not been finished，不符合本句的句子结构。只能使用独立主格结构our work not finished。故A项正确。

You can relax if remembering everything is not your strong suit. Recent research makes the case that being forgetful can be a strength—in fact, selective memory can even be a sign of stronger intelligence.
Traditional research on memory has focused on the advantages of remembering everything. But looking through years of recent memory data, researchers Paul Frankland and Blake Richards of the University of Toronto found that the neurobiology（神经生物学） of forgetting can be just as important to our decisionmaking as what our minds choose to remember.
“The goal of memory is not the transmission of information through time. Rather, the goal of memory is to help improve decisionmaking. As such, transience(转瞬即逝) is as important as persistence in memory systems，” their study in Neuron states.
Making intelligent decisions does not mean you need to have all the information at hand, it just means you need to hold onto the most valuable information. And that means clearing up space in your memory palace for the most uptodate information on situations. Our brains do this by generating new neurons(神经元) in our hippocampus(海马体), which have the power to overwrite existing memories that are influencing our decisionmaking.
“If you're trying to deal with the situation and your brain is constantly bringing up multiple conflicting memories, that makes it harder for you to make a wise decision，” Richards told Science Daily.
If you want to increase the number of new neurons in your brain's learning region, try exercising. Moderate aerobic exercise like jogging, power walking, and swimming have been found to increase the number of neurons making important connections in our brains.
When we forget the names of certain clients and details about old jobs, our brain is making a choice that these details do not matter. Although too much forgetfulness can be a cause for concern, the occasional lost detail can be a sign of a perfectly healthy memory system. The researchers found that our brains facilitate decisionmaking by stopping us from focusing too much on minor past details. Instead, the brain promotes generalization, helping us remember the most important gist of a conversation.
“One of the things that distinguishes an environment where you're going to want to remember stuff versus an environment where you want to forget stuff is this question of how consistent the environment is and how likely things are to come back into your life，” Richards said.
If you're an analyst who meets with a client weekly, your brain will recognize that this is a client whose name and story you need to remember. If this is someone you may never meet again, your brain will weigh that information accordingly.
These findings show us that total recall can be overrated. Our brains are working smarter when they aim to remember the right stories, not every story.
