mean to 打算      ought to          應該plan to  計劃      want to          要想兩個不定式由and, or, except, but, than 連接時，第二個可省略to，尤其是兩個不定式緊密相連時。如：i intend to call on him and discuss this question again,我打算去拜訪他并和他談談這個問題。i’d like to lie down and go to sleep.我想躺下睡覺。you’re free to talk or laugh here.在這里你可以隨便說笑。i’m anxious to go and ask him about it.我急于去問問他這個事。do you want to have lunch now or wait till later? 你想現在吃午飯還是再等會兒？we had nothing to do except （to） look at the posters outside the cinema. 我們無事可做，只有看看電影院外面的海報。he had nothing to do except talk nonsense. 除了胡說八道，他沒別的事干。i would rather die than be insulted.我寧死也不受侮辱。i’ll do anything but work on a farm. 除了去農場干活，我什么都干。it’s easier to persuade people than （to） force them. 說服人容易，強迫人難。 it’s better to take a taxi than （to） wait here.搭出租車也比在這等強。句子中but后面的不定式帶不帶to，取決于but前面的句子里含不含do，只要有與do/did有關的詞（do作謂語，to do作定語等等），but后面的不定式就省掉to。i have no choice but to go there alone. 除了獨自一個去以外， 我別無選擇。i can do nothing but go there alone. 除了獨自一個到那里去，我別無選擇。i have nothing to do but go there alone. 除了獨自一個到那里去，我沒事可干。 he did nothing but cry all day long. 他除了整天哭，什么也不干。 【典型例題】例：用動詞的不定式結構完成下列句子：1）let’s _______ （早回家）.→ go home early2）i am going _____ （問問題）. → to ask some questions3）i’ve been hoping ______ （會見格林先生）ever since i left school . → to see mr. green4）it is difficult ______ （照顧這么多小娃娃）. → to look after so many babies5）he likes _____ （在月光下散步）. →to walk in the moonlight6）she is afraid ____（獨自去）. → to go alone7）i pretended ______ （睡著了）. → to be asleep8）i should like _____ （今晚去看那個話劇）. →to go to that drama tonight9）be careful ____ （別著涼）. →not to catch cold10）mr. green seemed ____ （越來越不喜歡他）.→to dislike him more and more11）it is too heavy _____ （你搬不動）. →for you to carry12）you have to work hard ____（考試及格）. →to pass the examination13）tom intends ____（找個新工作）. →to look for a new job14）what do you want ____ （吃）？→to eat15）i hate _  _ （這么早離開）,but i am afraid _   _ （我不得不這么早離開）. →to leave so early; i have to
