什么情况下只能用that引导定语从句?要举例子哈!8月5号中午前要答案哈
1)先行词是不定代词：
all,few,little,much,something,nothing,anything等.All that we have to do is to practise every day.
2)先行词被序数词或形容词最高级所修饰.
The first lesson that I learned will never be forgotten.
3)先行词被all,any,every,each,few,little,no,some,等修饰.
I have read all the book (that) you gave me.
4)先行词被 the only,the very,the same,the last 修饰时.
He is the only person that I want to talk to.
5)先行词既有人又有物时.
They talked of things and persons that they remembered in the school.
先行词是表示地点时,要根据从句的谓语动词是及物的还是不及物的.如果是及物的就用that(which),否则用where.
This is the house where he lived last year.
This is the house that (which) he visited last year.

限定性定语从句,顾名思义,是对先行词从本质或特征上进行限制的一种定语从句,它所修饰的词代表一个(些)或一类特定的人或事、物。例如:
A man who doesn't learn from others can't achieve much.一个不向别人学习的人是不能有多少成就的。
A man被限定后,指一类特定的人.这类定语从句是不能去掉的,否则剩下的部分就失去意义不能成立,...

限定性定语从句,顾名思义,是对先行词从本质或特征上进行限制的一种定语从句,它所修饰的词代表一个(些)或一类特定的人或事、物。例如:
A man who doesn't learn from others can't achieve much.一个不向别人学习的人是不能有多少成就的。
A man被限定后,指一类特定的人.这类定语从句是不能去掉的,否则剩下的部分就失去意义不能成立,或者含义不清,甚至让人感到莫名其妙。非限定性定语从句则不然,它只对所修饰的词作进一步的说明,去掉之后并不影响句子的整个含义。在形式上,非限定性定语从句与主句之间通常用逗号隔开。例如:
Finally we visited to the Giant Yangtze Gorges Dam, which is the greatest key water control project in the world at present.最后我们参观了长江三峡大坝,它是目前世界上最大的水利枢纽工程。
本句若去掉从句,主句部分的含义仍然完整。历年的高考中,非限定性定语从句都是出现频率最高的考点之一。因此值得我们注意。
二、引导非限定性定语从句时,只能用which(不用that)。例如:
Heat is another form of energy, which is as important as other kinds of energy.热是另一种形式的能量,与其他形式的能量一样重要。
从句表补充说明,而且关系代词which不能换成that。
三、引导非限定性定语从句的which可以指代前面的先行词,也可以指前面整个句子的含义。例如:
That Peter will marry Alice, which has not been announced yet, has spread around.彼特要娶爱丽斯这件事还没宣布,却已传得沸沸扬扬。
句子中的which指"彼特要娶爱丽斯"这整个句子的意思。
四、除which外,还可用when, where, who等关系代、副词引导非限定性定语从句。例如:
After graduation, I decided to stay in Chongqing, where I spent my childhood and four years of college life.毕业后,我决定留在重庆,在那里我曾度过了我的童年和四年大学生活。
Albert Einstein left Germany for the United States during World War II, when Jews were badly treated in Germany.第二次世界大战期间,爱因斯坦离开德国去了美国,那时犹太人在德国受到不好的对待。
五、在限定性定语从句中作宾语时,引导词可以省略,但引导非限定性定语从句的关联词不能省。试比较:
He was eager to go to the hospital to see his stepmother, whom he loved and respected as his own mother.他急于想去医院看望他的继母,他把他的继母当作亲生母亲一样热爱和尊敬。
The American journalist (whom / who) the announcer mentioned in the news broadcast is said to have been killed by the gangsters.播音员在新闻广播中提到的那位美国记者据说已经被匪徒杀害了。
两例中的关系代词都在从句中作宾语.由于第二例是限定性定语从句,可以省略关系代词;第一例中的引导词不能省略,因为它引导的是非限定性定语从句。
六、表示"正如"的含义时,通常用as引导非限定性定语从句,也可用which引导;但置于句首时,只能用as引导。
例如:
China has basically succeeded in defeating SARS, which / as we have expected.正如我们所预料的那样,中国已基本上战胜了"非典"。
As is well known to everybody, Taiwan is an inseparable part of China.众所周知,台湾是中国不可分割的一部分。
但是当非限定性定语从句是否定含义时,就只能用which(而不用as)引导。例如:
He didn't win the championship, which I hadn't expected.他没获得冠军,这一点是我没预料到的。

在定语从句中that其实是万能答案.
定语从句中你要先看先行词，如果是人就用who;是时间就用when;如果是那个就用which；如果是地点就用where;无论先行词是撒子都可以用that.
