If a fire happens, you will be responsible for leading all the
^^^^^^^^^^^(A)^^^ ^^^^^^^^^^(B)^^^
employees in your department through the emergency exits on the first floor.
^(c)^ ^^^^(D)^^
答案為A
問題 想知道A錯在哪 我查過資料 好像火災發生 要用broke out
是否這邊 happens的用法是錯的呢?
第二題
Ecology has the science concerned with interactions between organisms and
^^(A)^^ ^^(B)^^^^ ^^C^^^
organism and the envronment.
^^^(D)^^^
答案為A
想請問這邊是要改成 is 嗎
然後後面原句應該是which is concerned with...
這樣對嗎??
麻煩高手解答 謝謝:)
