1. Has it arrived yet? 它已到达了吗？
arrive, get与reach都有“到达”之意。① arrive是不及物动词，arrive in+大地方的名词arrive at+较小地方的名词。
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。
1.When des the train Lndn?火车什么时候到达伦敦？2.They schl at 7 ’clck in the mrning.他们早上7点到校。3.What time des the plane New Yrk?这架飞机几点到达纽约？

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……
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. Have yu heard the _______ news? latest adj. 最近的；最新的 e.g. The news is all abut the latest meeting. 这条消息是关于最近的会议的。 latest 也意为“最晚的” e.g. Jenny was the latest student t cme t schl in the class this mrning.
4. 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”，
just/already/yet用法小结just “刚刚”；already “已经”，一般置于have/has之后，两者都用于肯定句；yet 用在否定句和疑问句，表示“还未”。
5. The jurney has taken several mnths. 行程历时几个月。 n sth 我们花了一个小时发这个电子邮件。

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”（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。
