    1．直到那时他才意识到，一个人如果遇到困难就任凭命运的摆布，永远也无法实现自己的预期目标．（ Not until…．）No tuntil then did herealize that a person couldn't accomplish/achieve his expected goal/ambition for good if he was at the mercy of fate when coming across difficulties．．

    分析 直到那时他才意识到，一个人如果遇到困难就任凭命运的摆布，永远也无法实现自己的预期目标．

    解答 答案：Not until then did he realize that a person couldn't accomplish/achieve his expected goal/ambition for good if he was at the mercy of fate when coming across difficulties．
    解析：根据所给中文及括号内的not until可知，前面的时间状语从句该使用部分倒装结构（not until后面接副词、介词短语或时间状语从句时，其后的句子要使用部分倒装）．另外根据中文题干可知，本题还考查at the mercy of fate"任由命运的摆布"、come across"遇到‘碰到'"这两个重点短语．最后需要根据"那时候"确定本句的时态为一般过去时．

    点评 本题考查句子翻译，做此类题目时一定要根据中文及英文题干确定需要翻译的成分，再找出与之对应的英文并考虑各成分是否有形式的改变．

    9．Does solving a math problem give you a headache？Do you feel nervous when you sit a math exam？For most students，math can be tough but scientists have proved that math problems can actually trigger（引起） physical pain．
    Scientists came to this conclusion with an in-depth experiment，which was published in the Public Library of Science One journal．They began by finding out how much participants fear math．Those involved were asked a series of questions such as how they feel when they receive a math textbook or when they walk into a math lesson．
    Based on their answers，participants were divided into groups．One group was made up of people who were particularly afraid of math and participants in the other group were more comfortable with the subject．
    Both groups were then given either math tasks or word tasks．When a math task was going to come next，a yellow circle would appear but when a word task was soon to come，a blue square would be shown．
    Using a brain-scan machine，scientists noticed that whenever people from Group One saw a yellow circle，their brain would respond in a way similar to when their body is feeling pain．It was like the pain they would feel，for example，if they burnt their hand on a hot stove．But they reacted less strongly when they knew that they would be faced with a word task．
    However，scientists saw no strong brain response from people in the second group．
    Math can be difficult，and for those with high levels of mathematics-anxiety （HMA），math is associated with tension，apprehension（忧虑） and fear．"When you are really thinking about the math problems，you r mind is racing and you are worrying about all the things that could go wrong，"explained Ian Lyons from University of Chicago，US，leader of the study．"The higher a person's anxiety of a maths task，the more he activated brain regions associated with threat detection，and the experience of pain．"
    More interestingly，the brain activity disappeared when participants actually started dealing with the math tasks．"This means that it's not that math itself hurts； rather，the expectation of mathis painful，"Lyons said．
    Based on the study，scientists suggested that things could be done to help students worry less and move past their fear of math，which might mean they perform better in tests．
    72．In the first stage，scientists ask participants some questions toB．
    A．see whether math hurts                  
    B．find out how much they fear math
    C．observe how their brain response            
    D．test their endurance of pain
    73．The underlined word"the expectation of math"is closest in meaning toD．
    A．the attempt of learning math                
    B．the motivation to work out math problem 
    C．the effort to understand math               
    D．the act of thinking about math
    74．Which is the best title for the passage？C
    A．How to overcome math fear．
    B．Physical pain affects math performance．
    C．Math pain in your brain．
    D．Unknown truth about pain．
    75．What can be concluded from the experiment？D
    A．The expectation of math has no relation to students'confidence in math．
    B．Moderate mathematic anxiety improves students'academic performance．
    C．Effective solutions have been worked out to lower students'anxiety of math．
    D．Physical pain caused by HMA disappears in the process of doing math problem．

    Human beings are so smart that we are capable of handling emergencies，reading people's feelings and becoming close friends with each other．But are we as smart as we think？

    So，are you also a （30）Kof smart phone's intelligence？The first skill many people have lost is remembering phone numbers．Because phone numbers are stored in smart phone （31）A，there's now no need to dial a number or look at it again．This is fine until you need to call someone for help，only to find your phone is not around．

    We are social creatures and need device-free time．Therefore，the easiest solution to social skill loss is to take a break from electronic devices．
