This kind of books are popular with all the students 这句话中哪里错了?

are 改为 is

没错
当主语前有“kind of …”结构修饰时：
(1)若是“this / that kind of +名词”(“这/那种...”)或“What kind of +名词”(“哪种…”)结构时，该名词可用单数，也可用复数。谓语动词的单复数取决于名词的单复数。如 This kind of apple is sweet. / What kind of apple is sweet? // This kind of apples are sweet. / What kind of apples are sweet?
(2)若是“these / those kinds of +名词” (“这些/那些种...”)或“What kinds of +名词” (“哪些种...”)结构时，无论名词是单数还是复数，谓语动词一律用复数。 如 These kinds of apple(s) are sweet. / What kinds of apple(s) are sweet?

将are 改成is
this /that kind of 词组用作主语时,无论of后面的名词是单数还是复数,其谓语动词只能用单数形式而不能用复数形式.
these／those kind of用作主语时,不论其后面所跟的名词是单数还是复数,其谓语动词应是复数形式
