Child as / though he is , (=Though he is a child,) he knows a lot .虽然他是一个孩子，但他懂得很多。 2. Cold as / though it is, (= Though it is cold,) the children play outdoors.虽然天气冷，但孩子们仍在户外玩。注意点:as引出的状语从句多用于书面语，它比用though或although引导的从句，语气强，更有表现力，从句常放在句首，语序部分倒装。even if /even though引导让步状语从句e.g. 1. Ill go even if (though) it rains tomorrow.即使明天下雨，我也要去。 2. Well make a trip even though the weather is bad. 即使天气不好，我们也要去远足。注意点:even if 和even though的意思为“即使”“纵使”有退一步设想的意味，多用于书面语中。有时也有“尽管”的意思.II让步状语和让步状语从句no matter (who, what when, where which, how)引导让步状语从句no matter +疑问词 或疑问词+后缀ever 。e.g. No matter what happened, he would not mind. 不管发生什么，他不在意。=Whatever happened, he would not mind. 替换：no matter what = whateverno matter who = whoeverno matter when = wheneverno matter where = whereverno matter which = whicheverno matter how = howevere.g. 1.Do it no matter what others say.不管别人怎么说,尽管干。=Do it whatever others say.2.

Whatever happens / may happen , we shall not lose heart.无论发生什么，我们都不要失去信心。 2). Whoever comes, he will be welcome. 无论谁来，都会受到欢迎。2. whever从句中的动词有时可以和may连用。3. 注意：no matter +疑问词 不能引导主语从句和宾语从句。（错）No matter what you say is of no use now.（对）Whatever you say is of no use now.你现在说什么也没用了。 （Whatever you
