有几道英语语法题求解说。。。非常感谢了。。

ABAACAB-7
DCCACAB-6
DBCACAB-2
D_C__ A_-4
看来只需要再答1、2、3题就可以了。
Bungee jumping is an adventurous sport, popular with young adults, _______ courage matters more than strength.
A．whose B．that C．of which D．where
答：D
译：蹦极是一项冒险运动，在年青人中流行，在这项运动中，勇气比力量更重要。
析：非限制性定语从句，先行词是an adventurous sport, 从句不缺乏主、宾，用关系代词where相当于介词in+ which 排除ABC

it is morning ( )we have four classes,not afternoon 填which还是when？
答：选when
译：当我们上4节课的时候，时间是上午，不是下午。
析：本题句确实有点怪。两个选项中不可能是which, 应在when和that中选取。
两个句型：
1.　it was +时间点+when sth. happened.
2. 强调句型：it is /was +被强调的主语、宾语或状语+that+剩余句子部分。去掉这三个结构词，句子应仍成立。显然本题不是强调，如为强调时间状语，则应为：It is in the morning that we have four classes, not in the afteernoon.
原题句待考证。

悦考网上有一篇阅读理解原文如下
Dear Su Wen,
Thank you for your e-mail. Your school life is very interesting. I hope I can go to visit you soon. Now I would like to tell you something about my school life in China.
I am a middle school student. I have to go to school from Monday to Friday. Classes usually begin at 7:30. First I do some reading. Then 【I have four classes in the morning and three classes in the afternoon.】 My favorite subject is computer. I can't watch TV because I have a lot of homework to do. On Saturday and Sunday morning I get up late because I'm too tired. But last year I was in a primary school(小学). I didn't go to school so early. I often watched TV in the evening because I wasn't so busy. I didn't have to get up so early.
Yours,
Wang Hai
类似的句子我记得以前的英语教材中出现过。
究竟原题是什么，谁改编了谁，不是很清楚。
但我认为2010吉林二模的题目，出得欠水平，欠考虑！
此题模仿04年天津高考题而作
It was evening ________ we reached the little town of Winchester .
　　A. that B. until C. since D. before

Nowadays when people talk about magicians，the first one comes into their mind is
Liu Qian．
A．whom B．which C．that D．what
答：C
译：现今人午谈论魔术师时，第一个想到的人就是刘谦。
析：限制性定语从句，先行词为人，在定从中作主语，排除ABD

1、A，这里是指这种运动的，不要以为whose只能指代人，它还可以指代物。

2、when，因为其为时间，所以这里用when来代替

3、A，这里是代替the first one,因为从句缺少主语，所以要用它

4、A,the only后面只能用that，这是定式，无法改变，所以没有太多解释的
　　
5、C,这个也是that用法中的一种定式，无法改变，只能硬背

6、A，这里用which/that/不填都可以，因为这里从句缺少宾语，这是缺少宾语需要的形式
　　
7、B，因为plan前面有the very修饰，先行词前面有only,any,few,little,no,all,one of,the same,the very等词修饰时 都只能用That
希望对你有帮助，特意排了一下版

1D_______ courage matters more than strength.这个定语从句修饰an adventurous sport，而an adventurous sport在这里是抽象地点.故选where

2.我感觉你可能打错字了。似乎应该这样：it is in the morning (that )we have four classes,not afternoon（根据句意，只有这样才对）

3.C.定语从句题。whom作宾语，故错误；先行词有first修饰用that故不用which;what不引导定语从句，而此处根据需要是必须定语从句的。
4.A 先行词gas前年有only修饰，关系代词用that
5.C 先行词前年有all修饰，关系代词用that
6.A the way( ) you speak to her括号内三种形式：不填，that，in which

7.B 先行词前年有very修饰，关系代词用that

上面有个两个同学都回答了，差不多都正确。candy320z同学回答都正确，aZ51525393有几个我个人觉得有疑义。

1、D．where 相当in which，在这项活动中，比起力量更需要勇气。
3、C．that candy320z解释的很专业了：“定语从句 先行词有序数词修饰用关系代词that”。在该从句是作主语指代人“刘谦”，而A．whom是作宾语。
6、A./ 这里是用in which而不是which，用which的话应该是 the way…… you speak in

1.D 定语从句 相当于in which，在这项活动中需要勇气···
2.when 同上，相当于是in the morning
3.C 定语从句 先行词有序数词修饰用关系代词that
4.A 同上 有the only修饰也用that
5.C 不定代词all修饰用that
6.A 先行词way 定语从句用that/in which/或都省略
7.B 同3.4.5 the very修饰液用that
