【正文】 我認為是我們心情的變化。A. to laugh笑，不定式形式，B. laughing笑，動名詞形式，C. laugh笑，動詞原形，D. laughs笑，三單形式。12．C解析：C【詳解】句意：麥克斯是一個搞笑的男孩?？疾楣潭ù钆?。本題就是第一種用法的被動形式。故選C。 考查非謂語動詞，having現(xiàn)在分詞形式；have原型；to have不定式；had過去式或過去分詞。故選B。acting現(xiàn)在分詞；to act動詞不定式；act動詞原形；acts動詞三單。9．B解析：B【詳解】句意：生活就是等待合適的時機去行動，因為每個人都在自己的時區(qū)。此處是“目的是為了取得成功”。achieving實現(xiàn)，現(xiàn)在分詞或動名詞形式；achieve實現(xiàn)，動詞原形；to achieve實現(xiàn)，動詞不定式； to achieving語法錯誤。8．C解析：C【詳解】句意：“早起的鳥兒有蟲吃”的意思是你必須先于別人做一些事來取得成功。根據(jù)句意，“卷起新褲子的目的是為了防止落灰”，to do不定式可以在句子中作目的狀語。考查to do不定式作目的狀語。whom為疑問代詞，talk 為不及物動詞，其后必須加介詞to，whom做介詞to的賓語，即whom to talk to。英語中what，who，whom，which，whose是疑問代詞，這些代詞在句中可作主語或賓語；when，where，how，why是疑問副詞，只能作狀語，不能作主語或賓語。whom to talk，whom為疑問代詞，talk為不及物動詞，不能直接跟賓語，所以形式錯誤；when to talk什么時候說；who to talk to和誰說；when to talk to形式錯誤，其中when為疑問副詞，不能做talk to的賓語，根據(jù)答語“You can e to me whenever you need. 你需要的時候可以隨時來找我”，可推測上文句意為“我不知道該和誰談談”，故選C。——你需要的時候可以來找我。觀察句子，這里應該是疑問詞加不定式“how to do sth”表示怎樣做什么，故選A。這確實幫助我養(yǎng)成了用水的好習慣。故選B。how to read怎樣閱讀；which to read讀哪一本；when to read何時閱讀；where to read在哪里閱讀。《了不起的狐貍爸爸》是我的首選。4．B解析：B【詳解】句意：——張老師在閱讀課上推薦了很多書。To collect 動詞不定式；Collecting 動名詞/現(xiàn)在分詞；Ccollect 動詞原形；Collected動詞過去式。3．A解析：A【詳解】句意：——為什么學生們需要每天閱讀？——為了收集寫作的信息。分析句子結構可知，空格處作后置定語修飾主語Most of the artists，應用過去分詞形式表被動。考查非謂語動詞。finish to do ，固定短語；根據(jù)句意語境，可知選B。 go D．doing。 going B．doing。 protected55．Dear friends, ________ your best and relaxing yourselves are two helpful ways to get a high grade in this exam.
