36、r than 20 seconds was associated with brain diseases without symptoms. Overall, those with brain diseases were older and had high blood pressure than those who did not have such diseases.Short onelegged standing time was also linked with lower cognitive score. Although previous studies have examined
37、 the connection between physical abilities and the risk of stroke, this is among the first studies to closely examine how long a person can stand on one leg as an indication of their overall brain health.Dr Tabara and his team also found a strong link between struggling to stand on one leg and incre

64、e)61really考查副词。此处修饰动词did，应该用副词，故填really。62listened考查动词的时态。结合全文时态可知，此处应填listened。63a考查冠词。“我”倾听一位英国朋友描述他的祖母的第一段屈辱的婚姻。根据句意可知，此处泛指某位英国朋友，且 British是以辅音音素开头的词，故用不定冠词 a。64marriage考查名词。由空前的“his grandmothers abusive”可知，此处应填marry的名词形式，指“屈辱的婚姻”。65but考查并列连词。“我”有时候会说话，但是大多数时候“我”都在倾听。根据句意可知，空处表示转折，故填 but。66might
65、have missed考查虚拟语气。空前是if引导的条件状语从句的倒装，引导词if省略，且从句是对过去情况的虚拟，所以主句用“would/might/could/shouldhave done”结构，根据语境可知，此处表示不那么确定的猜测，所以填might have missed。67centers考查名词。center作“活动中心”讲时为可数名词，再由前面的one of 可知，此处填centers。68to hear考查非谓语动词。此处用“特殊疑问词不定式”结构作knew的宾语，表示“学会了如何倾听”，故填to hear。69that考查强调句型。分析句子结构可知，“its in those
66、 moments . and perhaps about .”是一个强调句，强调的是时间状语in those moments，故填that构成强调句型。70myself考查反身代词。此处指也许“我”更了解自己了，故填反身代词myself。.写作规范增分练第一节：短文改错(共10小题；每小题1分，满分10分)Nowadays more and more people are concerning about their health, but how to keep health?
