參考答案及解析:
1.companying-accompanying. 動詞accompany和名詞company不要混淆。company是名詞，除了“公司”的意思之外，還有“陪伴，伙伴”的意思。比如：Keep somebodycompany(陪伴某人)，have no company(沒有伙伴)。accompany作為動詞“陪伴”的意思，如：accompanysomebody on a trip。
2.has-had.這里講的是1881年的地震，應該用過去時態(tài)。
3.were-are.雖然主句是過去時態(tài)，但是because從句中講的是沒有時間限制的一般道理，不因為時間的改變而改變，所以應該用現(xiàn)在時態(tài)。
4.earthquake-earthquakes.這里說的是1819和1845年的兩次地震，所以對應的名詞應該是復數(shù)形式。
5.^sea-the.sea 前通常要帶定冠詞，這屬于習慣用法。另外，表示具體的海洋，江河等名詞前通常也有定冠詞。
6.in-from.result in 和result from的區(qū)別是：前者介詞in后面跟結(jié)果，后者介詞from后面跟原因。從上下文來看，是說地震引起海浪，所以應該用from。
7.adjacent^-to.形容詞adjacent可以直接放在名詞前做定語，例如：an adjacent city(一個臨近的城市)。但是如果做后置定語就要和介詞to搭配，例如： a city adjacent to Shanghai。
8.considerate-considerable.considerate意思為 “體貼的，周到的”，considerable意思是“相當大的，相當多的”。
9.and-but.前文說12到15米高的海嘯給Ormara和Pasi兩個地方帶來了很大的損失，而Combay海灣的海嘯有15米高，卻沒有災難記錄。從前后句的邏輯關(guān)系來看，二者是對比轉(zhuǎn)折，所以應該用but。
10.whcih-where.先行詞是Mumbai，在非限制性關(guān)系分句中做地點狀語，所以應該用關(guān)系副詞where引導。
