Psychologically there are two dangers to be guarded against inold age. One of these is due absorption in the past. It does not__1__ work to live in memories, in regrets for the good olddays, or in __2__ sadness about friends who are dead. One'sthoughts must be directed to the future, and to things whichthere is something to be done. __3__ This is not always easy;one's own past is a gradually increasing weight. It is easy tothink for oneself that ont's emotions __4__ are used to be more vivid than they are, and one'smind more __5__ keen. If this is true it should be forgotten, and if it is forgotten it will probably notbe true.
    The other thing to be avoided is clinging to youth in hope of __6__ sucking vigour from its vitality.When your children are growing up __7__ they want to live their own lives, and if you continue tobe as interested in them as you were when they were young, you are likely to become a burden tothem, except they are unusually callous. I do not __8__ mean that one should be without interestin them, but one's interest should be contemplatory and, if possible, philanthropic, but not __9__unduly emotional. Animals become indifferent to their young as soon as their young can look afterthemselves, but human beings, owing to the length of infantry, find this difficult. __10__
    參考答案及解析:
    1.due-undue。如果是due absoption，就沒有必要說twodangers to guarded against，所以這里犯了語義顛倒的錯誤。
    2.work-do。work在這里用得不好，應(yīng)該為do，表示“能……”，work往往表示“行不行得通”，如：It does not workto employ two people. We need at least 5.
    3.^which-about。這里缺少了介詞about，使先行詞things 和something to be done無法連接。
    4.for-to。to think for oneself表示“為自己著想”，這這里顯然不是這個意思，應(yīng)改為to oneself 表示“自己想……”，類似于to say to oneself。
    5.are(used)-/。be used to 表示“習(xí)慣于……”，而這里的意思是“過去曾經(jīng)……”，所以應(yīng)改為usedto do。
    6.^hope-the。詞組in the hope of 或 in hopes of 表示“懷著……的希望”。
    7.growing-grown。be growing up 表示“在成長的過程中”，而這里表示的是“當孩子們長大以后……”，所以應(yīng)改為are grown up。
    8.except-unless。except表示“除了……之外”，在意思上不貼切，應(yīng)改為unless表示“除非……”。
    9.contemplatory-contemplative。沒有contemplatory這個詞，有的是contemplative，表示“沉思的，冥想的”
    10.infantry-infancy。infantry表示“步兵，步兵團”，應(yīng)該為infancy，表示“幼年”
