　　參考答案：

　　1.把for改為of。與fear搭配的介詞通常是of，表示對…的恐懼。

　　2.在no matter后面加上how

　　3.在studied前面加上has。本文的基調是一般現在時，此句的主語也是現在時，定語從句介紹Roberts做過的研究項目，所以用現在完成時比較合適。

　　4.把associations改為associates。本句的意思是：一項對高齡心臟病人的研究發現，有兩個或者兩個以上親密伙伴陪同的病人在一年危險期的幸存幾率是完全無人陪伴的病人的兩倍。

　　5.在poison前面加上a。不定冠詞修飾不可數名詞，該名詞后面再加上定語成分對該詞進一步說明。

　　6.刪除been

　　7.把sure改為surely

　　8.把but改為and。本句與上一段最后一句在結構(just as)上相似，在意義上是遞進關系，不應該用轉折連詞銜接，用and合適。

　　9.把his改為their。此處的代詞應該代替the oldest old， the oldest old 表示一類人可以用單數也可以用復數，但是下文提到這些年事極高的老人都用了復數，所以此處也要改為復數，使上下文一致。

　　10.把in改為at。詞組at every turn意思為 時時，經常。
