The English like to be with their families.
多個形容詞作定語修飾名詞的順序：
冠詞序數詞基數詞性質狀態(描述性)形狀大小新舊老少顏色國籍材料名詞。如：the second five interesting big new red Chinese wall papers.
2、形容詞比較等級的形式

C Taking more of the medicine
D More medicine taken

例4 Mr Smith was ____ moved at the news.
A deep B deeply C very deep D quite deeply
解析：該題正確答案為B。A.deep用于副詞時，修飾具體的深，如dig deep,而B-deeply則修飾表示感情色彩的詞，如該題為deeply moved.另如deeply regret等。而D-quite和deeply均為副詞，不能互相修飾。

例1 Do you know any other foreign language____ English?
A except B but C beside D besides
解析：A、B兩項except等于but，意為"除了…"，C-beside意為"在…旁邊"，不符合題意。而D-besides,意為"除了…之外，還有"。所以該題正確答案為D。該題意為：除了英語外，你還知道別的語言嗎?
例2 He suddenly returned ____ a rainy night.
A on B at C in D during
解析：我們均知道，at night這一短語，但如果night前有修飾詞，表具體的夜晚，則要用介詞on來修飾，故該題正確答案為A。
例3 I’m looking forward ____your letter.
A to B in C at D on
解析：該題正確答案為A。look forward to為固定搭配，意為"期望、盼望"。
