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

Answer 2

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，特意排了一下版本回答被网友采纳

Answer 3

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

Answer 4

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

Answer 5

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
