張老師好，麻煩您解答一下“he was able to see and touch a lion while still in the convenience of the VR studio”這句話中while和still的意思，以及這句話的意思，謝謝！

首先要注意，while后邊是一個(gè)省略句。狀語(yǔ)從句的省略須同時(shí)滿足兩個(gè)條件：①主句主語(yǔ)與從句主語(yǔ)一致；②從句謂語(yǔ)含有be動(dòng)詞。據(jù)此，我們可以把這句話中省去的主語(yǔ)he和be動(dòng)詞was還原，還原后的狀語(yǔ)從句為：while he was still in the convenience of the VR studio.

由此可見(jiàn)，這里while是時(shí)間狀語(yǔ)從句的引導(dǎo)詞，可以譯成“當(dāng)……的時(shí)候”，而still可譯成“依舊；依然”。這里的VR是virtual reality的縮寫(xiě)，可譯成“虛擬現(xiàn)實(shí)”。整句話的意思為：他依舊憑借“虛擬現(xiàn)實(shí)”工作室里設(shè)備的便利，看見(jiàn)并觸摸了一頭獅子。

張老師好！我在The Hunger Games 2： Catching Fire中看到一句話：… the warmth from the tea has long since leached into the frozen air. 這里的long是怎么用的？作名詞還是作形容詞？省略了什么嗎？謝謝！

這里long應(yīng)該是一個(gè)副詞，用來(lái)修飾其后的其他副詞或連詞，常見(jiàn)的搭配有：long ago、long before、long after以及l(fā)ong since。其中l(wèi)ong since的英文釋義是“If something has long since happened， it happened a long time ago”，即“很久以前”。例如：I've long since forgiven her for what she did. （對(duì)于她的所作所為，我早就原諒她了。）而在The Hunger Games 2： Catching Fire中這句話的含義為：茶的熱氣早就消散在冰冷的空氣中了。

Helping others is a habit， ___ you can learn even at an early age.該題設(shè)空處如果不用one，用其他引導(dǎo)詞的話，應(yīng)怎樣填？麻煩張老師解答一下，非常感謝！

首先可以肯定的是，這里可以填one，說(shuō)成：Helping others is a habit， one （that） you can learn even at an early age. 此時(shí)one作habit的同位語(yǔ)，one后面是省略了關(guān)系代詞that的定語(yǔ)從句。其次，如果要填入其他引導(dǎo)詞，可以填入which，說(shuō)成：Helping others is a habit， which you can learn even at an early age. 此時(shí)which引導(dǎo)非限制性定語(yǔ)從句，指代habit。

He was so foolish ____ his car unlocked.

A. to leave B. that leave

C. as to leave D. for him to leave

張老師，我不明白這道題為什么不能選擇A與D。請(qǐng)您解釋一下，謝謝！

本題正確答案是C，說(shuō)成：He was so foolish as to leave his car unlocked. 這里的“so … as to do”常常用來(lái)表結(jié)果。這句話意為：他當(dāng)時(shí)犯傻了，結(jié)果沒(méi)鎖車(chē)。注意，這里必須用as to do來(lái)與so搭配，而不是to do，因此選項(xiàng)A不正確。選項(xiàng)D不僅少了as，而且for him也是多余的，因?yàn)閠o leave的邏輯主語(yǔ)實(shí)際上就是主語(yǔ)he，無(wú)須再給出。

這道題如果不用“so … as to do”，還可以用enough to do，說(shuō)成：He was foolish enough to leave his car unlocked. 或者采用sufficiently說(shuō)成：He was sufficiently foolish to leave his car unlocked. 還可以用“so … that”或“such … that”，說(shuō)成：He was so foolish that he left his car unlocked./He was such a fool that he left his car unlocked.

注意，so as to與“so … as to”的用法不同，前者表目的，后者表結(jié)果。例如：We went early so as to get good seats. （我們?nèi)サ迷?，以便坐到好座位。?/p>
