though可和even 连用，表示强调。此外，though可放在句末，意为"然而"，although则不能这样用。

误区之八：混淆疑问词 + ever与no matter + 疑问词

【误】 It is generally considered unwise to give a child no matter what he or she wants.

【正】 It is generally considered unwise to give a child whatever he or she wants.

【析】 "no matter + 疑问词"在句中只能引导状语从句；"疑问词 + ever"在句中既可引导状语从句，也可引导名词性从句。

考点精练 考例回顾

1. The question is: what can we do to help them in their struggle for survival?

【考点】 struggle可以用作动词,常与介词for, with, against等连用；也可以用作名词，表示"挣扎；拼搏；努力；斗争等"。

【考例】 I realized strength and courage aren't always measured in medals and victories, but in the ________ we overcome. (2004天津卷)

A. sadness B. struggles

C. diseases D. tiredness

【简析】 根据上下文，这句话的含义应该为：我意识到力量和勇气并不总是用奖牌和胜利来衡量的，而是用我们战胜 / 克服（对手、困难或自我）过程中所付出的拼搏 / 努力来衡量的。因此选择B。

2. There are only about three hundred of these North American mammals left, none of which are in the wild.

【考点】这里"表示数量或部分的名词或代词 + of which / whom"引导一个非限制性定语从句，先行词指事物用of which，先行词指人用of whom，说明先行词的一部分情况。表示数量或部分的名词或代词（如基数词，分数，百分数, all, both, some, any, many, much, most, majority, minority, part, rest, none等）,既可以放在of which / whom的前面，也可以放在of which / whom的后面。

【考例】 The factory produces half a million pairs of shoes every year, 80% ________ are sold abroad. (2004辽宁卷)

A. of which B. which of

C. of them D. of that
