  • 第4题：

    资料：Because of the biochemical reactions in your body that occur with every type of food you eat on a daily bases, some foods age you faster than your real age, while other foods help to fight aging.
    Three of the processes that go on inside your body that have a major impact on your rate of aging are called “glycation”, “inflammation” and “oxidation”.
    When we talk about aging, we’re not just talking about wrinkles on your skin or how thick your hair is, we’re also talking about factors that you can’t see, such as how well your organs function, and whether your joints are degrading.

    According to the passage, aging is about all the following except--.

    A.the degrading joints
    B.the thinning of your hair
    C.the good condition of your organs
    D.the wrinkles around your eyes

    答案：C
    解析：
    【关键词】aging; except
    【主题句】第3自然段When we talk about aging, we’re not just talking about wrinkles on your skin or how thick your hair is, we’re also talking about factors that you can’t see, such as how well your organs function, and whether your joints are degrading. 当我们谈论衰老的时候，我们不仅仅是在谈论你皮肤上的皱纹或者你的头发有多厚，我们还在谈论你看不见的因素，比如你的器官功能如何，以及你的关节是否有退化。
    【解析】本题的问题是“根据本文，衰老是关于以下所有内容的，除了哪一项？”。选项A意为“退化的关节”；选项B意为“你的头发薄度”；选项C意为“你的器官状况良好”；选项D意为“你眼睛周围的皱纹”。根据主题句可知，A、B、D选项均与衰老有关，故选C。

    leave it in the hotel safe

    C

    put it in your front pocket

    D

    解析：

    正确答案： C
    解析：
    你把所有钱都花在买啤酒上，然后抱怨自己没钱，但是，你知道，你不可能鱼和熊掌两者兼得。have your cake and eat it too是英文中的常见表达，在中文中意思与“又想马儿跑，又想马儿不吃草”有异曲同工之妙。

    C

    get along with your colleagues

    D

    write reports to upper management


    正确答案： A
    解析：
    信息提取题。由第一句“Your boss also needs you to perform at your best in order to accomplish his objectives”可知，为了达到上司的目标，上司需要你尽力做到最好。A项是对题目的同义替换，因而是最佳选项。B、C项在文中都没有提到。D项张冠李戴，定位到第三段第二句“He needs your feedback in order to provide realistic and useful reports to upper management”，他需要你的反馈来向高管提供实际有用的报告，很明显是他给上层管理部门写报告而不是你，故排除。
