Question

10．我還沒學(xué)會(huì)怎樣使用這部手機(jī)．I haven't learned how to use this mobile phone yet．

Answer 1

分析 I haven't learned how to use this mobile phone yet．

解答 答案：I haven't learned how to use this mobile phone yet．結(jié)合中文表示還沒有…用現(xiàn)在完成時(shí)have/has+過去分詞，主語I，故have加上not縮寫haven't，學(xué)會(huì)learn的過去分詞learned，后加賓語，表示怎樣使用這部手機(jī)，我們用疑問詞+to do結(jié)構(gòu)作為賓語，故how to，使用use，這部手機(jī)this mobile phone 故how to use this mobile phone，還沒有加上yet放句末，故答案是I haven't learned how to use this mobile phone yet．

點(diǎn)評(píng) 動(dòng)詞不定式可跟在what，how，where，which，when等疑問詞（why除外）之后，構(gòu)成"疑問詞+to do"結(jié)構(gòu)．
此結(jié)構(gòu)常放在know，ask，find out，forget，decide等動(dòng)詞后作賓語．例如：
We must know what to say at a meeting．
我們必須知道在會(huì)議上說什么．
He could not tell whom to trust．
他不能區(qū)分該相信誰．
