改错题：Jimmy got some money from his parents every week,bu he always spent a lot of money on things he saw them although he didn’t need them.
答案删去saw后的 them
1.为什么删去saw后的 them呢?
2.got为什么不用改成get 不是every week吗?
2.He told us the experiment done in the （chemistry ）lab was a （chemical） change.
chemistry和chemical 在这里分别是什么词性阿?chemistry不是名词吗 为什么不是该填一个形容词吗?
thanks
xugx1919，你确定要改为gets吗 答案不用改的.

改错题：
1.定语从句he saw although he didn't need them是用来修饰things的.关系代词which/that代替先行词things并做saw的宾语,所以可以省略.如果你又用一个them,那么关系代词充当什么成分了?
定语从句有个特点希望楼主记住：关系代词代替先行词,并在定语从句中充当一定成分.
如：Do you like the city (which/that) you visited last year?
关系代词which/that代替先行词the city做从句中visited的宾语（可以省略）.如果在visited后加入一个it,反而犯了重复的错误.
2.英语句子很注重时态的对应.你可以看看后句中always后的spent,它也采用了一般过去时,当然尽管有every week,但是动词get还是用过去时got.
原因有二.一是改错题只能该一处,如果你改got为gets,那么spent不也要改成spends了?二是不能一看到every week或always就一定用一般现在时.这是不一定的,如：Now I'll tell you the story.now也不一定就是用现在进行时的啊!
填空题：
1.chemistry是名词,“化学（学科）”的意思.
chemical则是个形容词,“化学的”的意思.
2.在英语中,形容词固然可以修饰名词做定语,但是名词有时候也可以充当定语的.如：banana tree,maths teacher,woman doctor等.
至于到底是用形容词还是名词做定语修饰某个名词,关键是看表达习惯问题.这就只能看楼主平时的积累了,没有太多诀窍可言.
3.再如：
一个物理变化：a physical change 形容词修饰名词
一个物理老师：a physics teacher 名词修饰名词

因为money on things he saw them although he didn’t need them.是一个宾语从句省略了that 而that就表示了them 所以them是多余的
got 不用改成 gets 因为整个句子都是过去时 时态要一致 不要被 every week迷惑了
名词修饰名词作定语 而作定语的名词往往是说明被修饰名词的材料、用途、时间、地点...

因为money on things he saw them although he didn’t need them.是一个宾语从句省略了that 而that就表示了them 所以them是多余的
got 不用改成 gets 因为整个句子都是过去时 时态要一致 不要被 every week迷惑了
名词修饰名词作定语 而作定语的名词往往是说明被修饰名词的材料、用途、时间、地点、内容、类别

收起

1.因为这个定语从句修饰的宾语就是被修饰词things，所以saw后面无需在加宾语them
而即使有every week，但此句表示的是过去的一种状态，所以用一般过去时
2.名词也可作定语修饰名词，所以chemistry是可行的

1、因为已经有things，再有them就重复了
2、got就是要变成gets，every week一般现在时
2、chemistry名词 chemical形容词
填（chemistry ）lab 是因为名词作定语；就像apple tree 之类的
