重点难点讲解

辨析pain与ache

相同点：两者都表示疼痛。不同点：

pain要注意以下三个方面：

①  表示身体某部位不适时，属于可数名词；

I’ve a pain in my back. 我后背有点疼。

②  表示精神上的痛苦时，属于不可数名词；

He gave his mother much pain by failing all the subjects. 他所有的考试不及格使他妈妈很痛苦。

③作“努力”、“辛苦”讲时，只用复数形式，但不能用many, few修饰。

No pains, no gains. 不劳则无获。

ache表“疼痛”时，其主语是身体的某部位，而不是“人”。

My legs ache. = I have pains in my legs. 我脚疼。

注：head, tooth, stomach（胃）与ache一起构成复合名词，如：headache（头疼），但leg, foot, hand, forehead不行。

辨析asleep, sleepy 和sleeping

相同点：这三个词都具有形容词性质。不同点：

asleep意思是“睡着了,它是表语形容词，在句中只能作表语或宾语补足语，不能作定语。

The teacher found Tom asleep in class and kept him behind after school.

老师发现汤姆在课上睡着了，放学后把他留了下来。

sleepy意思是“想睡了”但并没有睡着。它可以在句中作定语。

I’m sleepy and I’d like to go to bed.老想睡了，我去房间休息了。

sleeping意思是“正在睡觉”。它可以在句中作定语。

They woke up the sleeping girl and asked her where her parents were.他们把那位正在睡觉的女孩叫醒，问她父母在哪儿。

辨析diet与food

相同点：diet, food都可作“食物”解。不同点：

diet指的是习惯的食物或规定的食物，特指维持健康的定量或定质的食物，如病人的疗养饮食。

The doctor has ordered me a special diet.医生给我安排了特殊的饮食。

注意：diet是可数名词，常与不定冠词a连用，如：

food是一般用法，凡能吃喝的具有营养的东西都称food. food是不可数名词，但在表示食品的种类时，可以用复数。

The doctor put him on a diet after operation.手术之后，医生规定了他的饮食。

Too many sweet foods will make you fat.太多的甜食会使你发胖。

辨析in the future 与 in future

相同点：这两个短语都表示“在将来”的意思，一般可以互换。不同点：
