同学,很高兴回答你的问题
正确答案如下：
1.选D
即：Why don't you buy a scarf for her?
翻译：为什么不给她买一个头巾?
解析：buy sth for sb.为某人买某物,固定用法,for 表示目的,对象
2.选B
即：Xiaoming doesn't work as hard as Li Lei.
翻译：小明没有李雷学习努力.
解析：work hard 努力学习,是固定搭配,另外as...as 中间要用形容词或副词的原级.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
不明白请继续追问,
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

o B: to buy; to C: buying ; for D: buy ; for
2. Xiaoming doesn't work ____ Li Lei.
A: as harder as B: as hard as C: so harder as D: so hardly as
1. 选D. buy sth. for sb.
2. 选B. work 为动词，用副词修饰

d Why don't you后只需动词原形，for为某人。整句翻译为：为什么不给他买一条围巾呢？
b as...as:和...一样。

1. 选D. buy sth. for sb.
2. 选B. work 为动词，用副词修饰，hard本身既是形容词又是副词。而hardly表示“几乎不”，意思错误。

1.答案D.buy sth. for sb.为谁买什么东西。
2.答案B.考的是比较级as...as，中间用形容词原形。

第一题选D,why don't you do ...是一种提建议的日常交际用语句型，buy sth. for sb
第二题选B， as ...as ，意思是 和某人/某物一样...省略号部分使用形容词或者副词的原级而不是比较级

buy
for1.为…买：
She bought an English dictionary for me.
她给我买了一本英语词典。
2.以…价格买下：
He bought it for ten dollars.
他以10美元买下它。
3.用现金买：
I bought the car from the store for cash...

buy
for1.为…买：
She bought an English dictionary for me.
她给我买了一本英语词典。
2.以…价格买下：
He bought it for ten dollars.
他以10美元买下它。
3.用现金买：
I bought the car from the store for cash.
我用现金从这家商店买下这辆汽车。
4.以金钱买：
Happiness cannot be bought for money.
幸福是金钱买不到的。

work hard 是固定说法，所以 work as hard as sb 也是容易理解的，as ... as 没有“更”的意思，用原级

我想，你可能纠结的是前面的这个 buy sth. for sb.
为什么不用 buy sth. to sb. ？
你可以这样理
give a scarf to her ，这样是可以的，因为动作 give 的受动对象是 直接宾语 a scarf 和间接宾语 her
buy a scarf for her 中，buy 的时候her不在面前，her不是间接宾语，直接宾语和间接宾语必须是动作发生时同时在场的

收起

1. D buy sth for sb 为某人买东西, why don't you do 为什么不干什么
2.B 这个是考的是副词的原级， 原级一般用as...词性的话用的是原型).. as
hard和hardly要区分好，hard本身就是副词，而hardly不是hard的副词形式，他的意思是几乎不，表示否定。

1.D
buy sth for sb为某人买某物
你为什么不给她买条围巾呢
2.B
as+adj/adv+as与...一样...，中间的词用原形，hard既可以是形容词又可以是副词
小明没有像李雷一样努力工作
