　　【译文】从他外表看，我们可以肯定他烟瘾很大。

　　【注释】conclude (from sth) that...“(从……)断定或得出结论……”。condemn“谴责，指责”。可以说condense sth into/from... to“把……压缩、浓缩为……;把……从……精简、精炼为……”，后面不能跟从句。conduct“进行，引导，带领”。

　　【注释】for(连词，引导从句)“因为”，该词为书面用语，只能放在第一分句后面，对其加以解释，补充说明原因。有时for并不表示原因，而是陈述事实，从这个事实可以推断出第一分句所说的情况。注意for和because的区别：because着重强调原因，for并不强调原因，而是附带加以解释。therefore表示“因此，所以”，放在此句中意思也说得通，但它是连词，不合语法。
