(4)go over“調(diào)查,視察;越過”。例如:
you must go over your lessons before the exam.
考試前你必須復習。

(1)have to 意為“必須,不得不”。例如:
do you have to take the test?
你必須考試嗎?
tom has to practice speaking chinese every day.
湯姆每天必須練習講漢語。
辨析:have to 與must
這兩個詞都可以表示“必須”。have to 更加強調(diào)客觀原因,而must則強調(diào)主觀原因;含有have to 的句子在作句型轉換時須借助于助動詞do,does或did,而must本身是情態(tài)動詞,進行句型轉換時可以直接通過must改變。例如:
it is raining, we have to stay at home.
天在下雨,我們不得不待在家里。
we must work hard.
我們必須努力工作。
lucy doesn't have to stand.
露茜不必站著。
you mustn't play in the street.
你不能在街道上玩。
(2)wait 是不及物動詞“等待,等候”的意思。可以用于詞組wait for sb.“等某人”,wait to do sth.“等著做某事”,wait for sb to do sth.“等某人做某事”。例如:
who are you waiting for?
你在等誰?
they can't wait to open the presents.
他們迫不及待地打開禮物。
you can wait for him to help you.
你可以等著他幫你。
6.unfortunately, by the time i got there, the bus had already left.
不幸的是,我到那兒的時候,公交車已經(jīng)走了。
unfortunately 是副詞“不幸地”,是由fortunately加否定前綴“un”構成的。英語中有一部分詞在詞首或詞尾加上前綴或后綴就可以變成另外一個詞。如:lucky(幸運的)-unlucky(不幸的),use(用)-useful(有用的),forget(忘記)-forgetful(健忘的),un作前綴表示“not”的含義,即“un”是一個否定前綴。例如:fit(合適的)-unfit(不合適的),fair (公平的)-unfair(不公平的),known(聞名的)-unknown(不聞名的)等。
7.luckily, my friend tony and his dad came by in his dad's car and they gave me a ride.
