Answer 1

答案：D;A;B;C;A;C;D;A
解析：

解析：這篇文章講述了狗作為人類的朋友，在許多方面給予人類的幫助。文章在時態(tài)和語態(tài)等方面變化多端，錯綜復(fù)雜，多處涉及到被動語態(tài)，以及各種時態(tài)之間的區(qū)別，答題時應(yīng)特別小心，注意區(qū)分。1．既然是故事，那一定是過去發(fā)生的事情，故用過去時helped． 2．句中l(wèi)ost in snow作定語修飾people. 4．用was表示過去發(fā)生的事情。 6．詞組quite a few表示“不少，許多”，易誤選為A． 8．該題強調(diào)一種狀態(tài)，即“還沒長大”。易誤選成現(xiàn)在完成時。 　　拓展延伸：提高完形填空答題能力的最好方法是精讀。對所遇到的文章進行反復(fù)研讀，揣摩文中語法、詞匯等各種語言素材在運用中的變化，使自己對語言變得更加敏銳。
