剖析：本題考查定語(yǔ)從句的引導(dǎo)詞。一般而言，當(dāng)先行詞為人，引導(dǎo)詞就用who；當(dāng)先行詞為物，引導(dǎo)詞就用which；或者都可以用that。但是在以下幾種情況中，先行詞只能用that：
1．先行詞是不定代詞時(shí)。如：She didn't forget anything that her mother had told her to buy.
2．先行詞被序數(shù)詞、形容詞最高級(jí)或被the last，the only，the very，the same等修飾時(shí)。如：
This is the first book that I studied in the primary school.
Have you worked out the most difficult question that our teacher told us to do?
This is the very book that you want to borrow.
3．先行詞是或被all，no，some，any，little，much等修飾時(shí)。如：
They haven't got any dictionaries that we need.
4．先行詞是兩個(gè)或多個(gè)分別表示人和物的名詞時(shí)。如：
He told us many interesting things and persons that we had never heard.
5．主句是以who，which引導(dǎo)的特殊疑問(wèn)句時(shí)。如：
Who is the man that you spoke to just now?
6．先行詞是主句的表語(yǔ)或關(guān)系代詞在從句中作表語(yǔ)時(shí)。如：
China is no longer the country that it used to be.
