例：我会讲英语。
I can speak English.
② 表示“请求”或“许可”。
例：你能帮我学汉语吗？
Can you help me with my Chinese
2. Students Wanted for School Show 学校(文艺)表演招募学生(演员)
① wanted的用法
wanted在此处用于招募人员广告标题，相当于汉语中的“招募，征集，招聘，寻求”等含义。常用结构：被招募或寻求的对象 +wanted +for +招募或寻求的组织或活动。
Teachers Wanted 招聘教师
Help Wanted 寻求帮助

② show n.演出；节目 v. 给……看；展示
show 在此处作名词，意为“演出，节目”。常用短语有：

school show 校园演出
talent show 才艺表演
The fashion show starts at 7:30 in the evening. 时装表演晚上7:30开始。
We want students for the school show.我们需要学生参加我们的校园演出。
show还可作动词，意为“给……看；展示”。show sb. sth.=show sth. to sb., 意为“向某人展示某物”。
Please show me your ID card.=Please show your ID card to me. 请给我看一下你的身份证。
如果show后的两个宾语都是人称代词，则只能用show sth. to sb. 结构。
Your new eraser is very nice. Can you show it to me 你的新橡皮很好看，你能给我看一下吗？
3. Can you sing or dance 你会唱歌或者跳舞吗？
or conj. 或，或者, 该句为选择疑问句。
选择疑问句是指提出两个或两个以上可能的答案供对方选择的句式。供选择的部分常用or来连接。需要注意的是：
(1) 选择疑问句不能用Yes或No来回答，而应该根据所给的选择对象和实际情况来回答。
(2) 读选择疑问句时，or前面的部分用升调，or后面的部分用降调。
—Do you like red or green 你喜欢红色还是绿色？
— I like red. 我喜欢红色。
若选择疑问句中有三个或三个以上并列部分，or用来连接最后一部分，前两个或两个以上的并列部分用逗号隔开。
例：你喜欢苹果、橙子还是香蕉？
Do you like apples, oranges or bananas
【拓展延伸】选择疑问句的前半句也可以是特殊疑问句。
—What would you like, coffee or tea 你想喝点什么，咖啡还是茶？
—Tea. 茶。
4. Please talk to Mr. Zhang after school. 请放学后跟张老师说。
(1) 本句是一个祈使句。祈使句常以动词原形开头，一般省略主语you。 有时为了礼貌，常在动词原形前加please。 please也可以放在句尾，前面常用逗号与其他成分隔开。
Please pass me a bottle of milk.= Pass me a bottle of milk, please. 请递给我一瓶牛奶。
(2) talk v. & n. 说话；交谈
talk在此处作不及物动词，常用结构：

Don’t talk to strangers! 不要对陌生人讲话！
Ms. Zhao often talks with Jim. 赵老师经常跟吉姆谈话。
