We have been best friends since primary school and spend almost every day with each other. 我倆自小就是最好的朋友，幾乎每天都在一起。句法分析：and 連接了兩個并列謂語，since引導(dǎo)了一個時間狀語，since可作為副詞直接作狀語，也可用作介詞引導(dǎo)時間狀語，還可用作連詞引導(dǎo)時間狀語從句。含有since及其引導(dǎo)的時間狀語（從句）的句子多用完成時，表示“自-一來一直”。如：I havent seen you since I came back. 我回來后一直沒看見你。 He has been working in the factory since 1995.自1995年以來他一直在這個工廠工作。 He moved to London after his parents died, and he has been living there since. 他的父母去世后他就搬到了倫敦，從那以后就一直住在那兒。6. On Monday, we had a surprise mates test. 星期一，我們進(jìn)行了一次意外的數(shù)學(xué)考試。句法分析：surprise 為名詞定語surprise n.to ones surprise/to the surprise of sb.另某人吃驚的是take sb. by surprise 突襲某人；使某人驚訝如：To our great surprise, he passed the exam. 另我們意外的是，他考試及格了。When he offered me the job, I was completely taken by surprise.他主動給我這項工作，真令我吃驚。補(bǔ)4頁難點分析： The river was almost frozen. 河水幾乎已經(jīng)結(jié)冰。 The streets were almost empty. 街上幾乎空無一人。 We see each other almost every day. 我們幾乎天天見面。拓展： Almost 和nearly意思很接近，都可譯為“幾乎”“差不多”,在不少情況下兩者幾乎可以換用。如：They have almost/nearly run out of food. 他們的食品幾乎已經(jīng)吃完了。同步練習(xí)一、單項選擇：1.
