要 点 解 疑
①usual形容同,意为“通常的；平常的；习惯的”.加前缀-un则成为反义词即unusual,意为“不平常的、异常的”.
在英语中有很多形容词,加前缀-un之后成为反意词.
例如：happy高兴 unhappy不高兴
important重要的 unimportant不重要的
useful有用的 unuseful没有用的
unusual为多音节词,变比较级时加more,最高级加most.
例如：out going开朗的→more out going更开朗→most outgoing最开朗
②岁数的表示方法主要有三种：
例如：Amy is 16 years old． 句中除1岁外,其余必用复数years
Amy is a 16-year-old girl． 当作定语时结构为“基数词-year-old”.
Amy is at the age of 16． at the age of＋基数词
Amy is a girl of 16． n.＋of＋基数词.
③take care of¼意为“照料、照顾”,同意词组为look after.
例如：She takes care of everybody她关心大家.
Take care of your health注意你的健康.
Please take care of yourself请照顾你自己.
My mother is ill in bed. I must look after her.
母亲病倒了,我必须照顾她.
④named为动词name的过去分词,在此作定语修饰pig,可换作called.
name为动词.意为“给……取名”.
例如：They named their son John．他们给孩子取名为约翰.
The child is named after his father.
那孩子的名字是按他父亲的名字取的.
name意为“列举,说出……的名字”.
例如：Can you name all the plants in the garden?
你能说出花园里所有植物的名字吗?
Can you name some presidents of the United States?
你能说出一些美国总统的名字吗?
name为名词,意为“名字”.
例如：His name is Ben．他的名字是本.
⑤a lot意为“许多”,修饰名词必须是a lot of＋名词；修饰动词时直接放在动词后.
例如：I have a lot of homework to do．我有很多作业要做.
There are a lot of books in the school library.
在学校图书馆里有很多书.
I know a lot about her．我很了解她.
⑥too¼to太……以致不能（too之后接形容词和副词）.
例如：The boy is too short to reach the apples.
那个男孩子个太矮,够不着那些苹果.
He is too young to join the army．他年龄大小不能参军.
The man is too old to walk．这个人老得不能走了.
enough¼to“足够能……”是too¼to的相反句式.
例如：The box is light enough for me to carry．这个箱子很轻,我能抬得动.
The boy wasn't old enough to join the army.
那个孩子岁数不够,不能参军.
⑦It's easy to do sth．做某事容易
例如：It's easy to speak English．说英语很容易.
It's easy to learn Chinese well．学好语文是很容易的.
句式It's＋形容词（原形）＋to do sth．做某事怎样
例如：It's important to read．读书是很重要的.
It's difficult to learn English well．学好英语是很困难的.
