语法难点
一般将来时：将来时间计划发生或将要发生的动作和存在的状态。常与表示将来的时间状语连用，如：tomorrow ….,next …,the day after tomorrow , in 5 minutes ,soon,等。
构成：will do/be & be going to do/be
例如：I’ll help clean the city parks next week
高频考点
1.hunger n.饥饿 adj.饥饿的
Eg. In the old days, many people died of hunger.旧社会，许多人死于饥饿。
2.homeless adj.无家可归的。在名词词尾加后缀less变为否定形容词。
如：1) help+less=helpless : 意为“无助的;
2) care+ less=careless意为“粗心的”;
3)hope+ less=hopeless“无望的”; 4) use+ less=useless“无用的”;
3. set v.摆放、放置、（太阳）落下set up 建立set off=set out 出发、动身
4.cheer v. cheer up sb.或cheer sb. up意为“（使某人）高兴起来，振作起来”。如果是代词做
宾语，则将代词放在中间。
5.fix v.修理 fix up相当于repair，表示“修理，修补，整理”,其后跟物件名词作宾语。特别提
示。如果fix up的宾语是“人”的话，则构成fix sb. up with sth.句型，表示“为某人安排某件
事，向某人提供某物”。
Eg：I’ll fix you up with a place to stay. 我来给你安排住处。
6.similar adj.相似的 be similar to意为“与……类似”; be the same as“与……完全相同”。take
after sb. 表示“长相或举止像（某个长辈）”，不能用于被动语态。
7.pleasure意为“高兴，快乐”，是不可数名词；表示“乐趣，高兴的事”时是可数名词。
◎在口语中It’s pleasure. 是回答感谢的客套语。
— Thank you for your help. 感谢你的帮助。
—It’s a pleasure. 不用谢。
特别提示
◎pleased是形容词，意为“自己感到高兴的，欣喜的，满意的，其主语为人。
◎pleasant也是形容词，表示“使人感到愉快／满意”，一般用作定语，如主语是物，也可以用作表语。
Eg. It’s pleasant weather today. 今天的天气令人愉快。
It’s very pleasant to sit down after standing for hours.
站了几小时后坐下来很舒服。
◎please是动词，表示“（使）高兴，满意，愉快”。
8.shut v, (shut, shut) “关”，在许多情况下可以与close互换，只是后者语气较弱，Eg. close the
door关门（也可能指半开半闭），shut the door关门（指把门关紧）。◎当表示“关闭公路，
铁路或交通工具”或作“结束”讲时，只用close。
Eg：They have closed the road for thick fog. 由于大雾，那条公路被关闭。
特别提示
turn off用来表示“关闭”有开关的东西，如收音机、电视、煤气、水龙头等。
9. carry v.“搬运，携带”，不表示带到什么地方，而携带的方式可以是提、扛、背、抱、抬等。
10. fetch v. 相当于go and bring back，意为“取来，接来”，表示一往一返。

I haven’t written my blog(博客) for two weeks because I’ve been really busy with my work. And for me, being busy is being 1 , for I really like my work. I have been finishing up my volunteer work for Doctors without Borders. I 2 some Wharton classmates around to see Shanghai (actually, to see Shanghai bars), and also hung out with some online friends I met on Pop English. It’s too bad I don’t have 3 to actually meet all the people I’ve met on this website—sometimes I hardly have time to 4 the messages I get from the other friends.

五、阅读理解
On June 26, 2000, two scientists, called Francis Collins and Craig Venter, told the world that they could now read the whole “map” of the human body: DNA. DNA is something that everybody has, and it tells the body what to do. DNA is the reason that we look like our mother and father, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time. In 1860, Gregor Mendel discovered a special reason why we look the same as other people in our family. It is because of small things named “genes” in our body. In 1953, James Watson and Francis Crick made another discovery and found out that those small parts are real messages written in the DNA with a special language.
In 1961, Marshall Nirenberg and Johann Matthaei found a message in DNA showing how DNA tells the cell (细胞) to build its parts. Scientists have now found all the words in the DNA map, but we still do not understand what they all do. By understanding what just one “word” means, we can help save more people from several illnesses.
Most people hope that this will help make better medicine and help sick people. Other people worry that when people begin to know more words and find out lots of other information, we might use it in a wrong way, just to make people more attractive, or stop sick people from getting jobs. Man would have to meet a lot of trouble if DNA technic wasn’t limited in use.

A. Make people get new jobs. B. Make medicine for illnesses.
