Lesson18 教材知识详解1. What does he/she look like? 他/她长什么样？(1)本句是用来询问某人的外貌的，其句型为“ What do/does +主语+look like?”回答时可用“主语+系动词+形容词”或“主语+ have/ has+(a/an+)形容词+名词”表示。
如：—What does your father look like? 你的爸爸长什么样？一He is tall and thin.他又高又瘦。
(2)look like意为“看起来像”，后面可接名词、代词等作宾语。
其中look为系动词，表示“看起来”，后面常接形容词构成系表结构。
like为介词，意为“像、如、跟……一样”。
如：She looks like her aunt.她看起来像她的姑妈。
2. Jenny is from Canada. 詹妮来自加拿大。
be from…意思是“来自……”，之后接表示国家的词，表示某人或某物来自某个国家。
如：I am from China.我来自中国。
come from也表示“来自”，可以与be from互换。
如：I come from China.=I am from China.我来自中国。
3. She has short blond hair. 她有金色短发。
当一个句子中同时有长短、颜色两个形容词来修饰名词时，我们通常把长短放在颜色的之前。
如：I have long, black hair.我有黑色的长发。
当一个名词有两个或两个以上的形容词修饰时，它们的顺序通常是：限定词+描绘性形容词+特征性形容词（大小、颜色等)+名词。
如：She has a beautiful white dress.她有一条漂亮的白色连衣裙。
hair意为“头发”，为不可数名词，作主语时，谓语动词用第三人称单数形式。
在指具体的几根头发时，hair可视为可数名词，复数在其后加-s。
