Language pints
1. Has it arrived yet? 它已到达了吗？When des the train arrive in Lndn?火车什么时候到达伦敦？
arrive, get与reach都有“到达”之意。① arrive是不及物动词，其后必须加介词才能跟宾语。arrive in后接表示洲、国家、城市等大地方的名词。而arrive at后接表示车站、学校、邮局等较小地方的名词。例如：
What time des the plane get t New Yrk? 这架飞机几点到达纽约？ They reach schl at 7 ’clck in the mrning. 他们早上7点到校。
② get也是个不及物动词，其后加介词t,再接地点名词；
③ reach是及物动词，其后可直接接名词或代词作宾语。
2. What are yu up t? 你在干什么呢？这么多书放在地上，他在干什么呀？What is he up t with all thse bks n the flr?
be up t用于表示 “忙于……，正在做……”。例如：
D yu want t stay r g? It’s up t yu.你是要留下还是要走呢？你自己定。
当我们说be up t sb.时，表示“由……决定”。例如：
3. I haven’t started yet. 我还没开始做呢。你收到她的信了吗？ Have yu received her letter yet?
yet用于否定句和疑问句，意思是“还，尚”。nt…yet的意思是“还没，尚未”，表示某事物在某一时间尚未发生，但未来也许会发生。例如：
4. The jurney has taken several mnths. 行程历时几个月。如: It tk us an hur t send this email. = We spent an hur sending this email. 我们花了一个小时发这个电子邮件。
take后面加时间常表示“花费（多长时间）”，常用句型为: It takes sb. sme time t d sth. 意为“某人花时间做某事”，常与句型“sb. spend sme time ding sth”互换。
5. That’s why it’s n the news.这就是它（宇宙飞船）上新闻的原因。在都柏林人人都很友好，这就是我喜欢这座城市的原因。 Everyne in Dublin is friendly, and that is why I lve the city.
that is why…表示“这就是……的原因”。
6. S have they discvered life n Mars? 他们在火星上发现生命了吗？
invent, find与discver的区别：① invent意为“发明”，指经过认识和实践创造出前所未有的事物； ② find意为“发现，找到”，指对某种事物的寻求，也指找到（丢失的事物）；③ discver表示“偶然或经过努力发现客观存在的事物、真理或错误” 。
Edisn invented the electric light bulb.爱迪生发明了电灯泡。 Clumbus discvered America but he did nt explre the new cntinent．哥伦布发现了美洲，可是他没有去探索这个新大陆。 I’m lking fr my pen but I can’t find it. 我正在找我的钢笔，但找不到。
