1、 Basketball has not only become a popular sport to play, but it has also become a
popular sport to watch.
not only…, but also… 不但……而且…… 若连接两个成分作主语，谓语动词与靠近的主语保持一致。（就近原则）
e.g.: Not only the students but also their teacher is enjoying the film.
不仅学生们在欣赏这部影片，他们的老师也在欣赏这部影片。
2、mistake 一词常用的词组
【扩展】：by mistake 错误地 make a mistake 犯错误
mistake...for...把...误认为...
3、Dr. Naismith divided the men in his class into two teams…
divide v. 分开；分散

shoes with special heels.有特别脚跟的鞋。
with是介词，意为“带有;具有”, 表示某物具有某种性质/状态。
e.g.: China is a country with a long history.中国是一个有着悠久历史的国家。
【括展】：with还有以下用法：
1)with介词 “和……一起”
e.g.: He likes to live with his parents.他喜欢和父母住在一起。
注意，当with表示“和……在一起”, 谓语动词与with前面的主语一致。
e.g.: He with his parents is going to visit Mount Tai next week.
下星期他和父母要去游泰山。
2)with指人随身“长着,戴着,带着...;有...的”, 表示人的某种特征。
e.g.: My teacher is an Englishman with golden hair.
我的老师是一个有金黄色头发的英国人。
3)with表示“随身带某物”

4)with说明名词, 表示事物的附属部分或所具有的性质“具有,带有,加上,包括...在内”。

5、辨析the number of， a number of
The number of foreign players,including Chinese players,in the NBA has increased.
外国运动员以及中国运动员在NBA的人数增加。
【辨析】：
①the number of…的意思是“...的数量”,作主语时,谓语动词使用单数形式。
②a number of的意思是“很多,许多”,作主语时,谓语动词使用复数形式。
6、be used for sth./doing sth 被用来做...
"be used for sth./doing sth."表示“被用于某物/做事”, for是介词, 后面跟名词、代词或动名词。
e.g.: --What is the hot ice-cream scoop used for 这个热的冰激凌勺是用来做什么的
--It’s used for serving really cold ice-cream. 它是用来供应非常冰的冰淇淋的。
7、辨析in the end, at the end of, by the end of
【辨析】：
1)in the end 表示经过许多变化、困难的情况之后,某事才发生, 意为 “最后,终于”, 相当于at last, finally, 后不接of 短语。
e.g.: With the teacher’s help,he passed the exam in the end.
在老师的帮助下,他最终通过了考试。
2)at the end of 意为“在...尽头/末端”
e.g.: Some of the students sat on the benches at the end of the room.
有几个学生坐在房间尽头的长凳上。
3)by the end of表示“到……末为止”,后接时间名词, 常与一般将来时, 完成时连用, 后一般接时间名词, 如年、月、周等。
e.g.: We will build the building by the end of the year. 到年底前我们就建这座大楼。
8、one of + 某物
"one of +复数名词/代词" 意为“...之一”, 作主语时谓语动词用单数形式。
e.g：It was quite delicious, and so, one of the world's favorite drinks was invented.
它十分可口，因此，世界上最受喜爱的饮料之一被发明。
9、pleasure, pleased, pleasant
1)pleasure 是名词 “高兴, 愉快, 乐趣”, 在口语中常用It’s a pleasure, With pleasure等作客套语。
e.g：—Will you go with me 你同我一起去好吗
—With pleasure.好。
2)pleased 形容词, 表示“高兴的, 满意的, 感到高兴的”, 主语只能是人。结构:
be pleased with/about sth.
be pleased to do sth.
be pleased+that从句
e.g：We are pleased with his work. 我们对他的工作很满意。
3)pleasant 形容词, 主语是物时，指“使人感到愉快的、高兴的”,
主语是人时，指“高兴的, 愉快的, 态度友好的”。
e.g：It's pleasant to work with you.与你共事令人愉快。
He spent a pleasant evening.他度过了一个愉快的夜晚。
10、It做形式主语的句子
It's hard to tell who came up with the idea first.谁第一个想到这个观点的，这很难说。
【点拨】：该句是主从复合句, who引导的是宾语从句, 作动词tell的宾语。
句中It作形式主语, 动词不定式to tell...是句子的真实主语。
【短语】：come up with “提出;想出”
Well, you do seem to have a point…
【点拨】：have a point 有道理
e.g.: I admit (that) you have a point. 我承认你有理。
【拓展】：
①think of 指“考虑, 记忆, 记起”
e.g.: You think of everything! 你全都提到了。
②think sth. over指“仔细想, 审慎思考, 作进一步考虑”。
e.g.: Please think over what I said. 请仔细考虑我说的话。
I want to think it over. 我想仔细考虑一下这件事。
③think sth. out 指“想通, 想出, 熟思”。
e.g.: He thought out a new idea. 他想出了一个新主意。
That wants thinking out. 那件事需要仔细考虑。
12、It is said that a Chinese ruler called Shen Nong was the first to discover tea as a
drink. 据说有一位叫作神农的中国统治者最早发现了茶可以饮用。
It is said that…表示“据说……”, that后面接完整的句子。
e.g.: It is said that thirteen is an unlucky number in many Western countries.
据说在许多西方国家13是个不吉利的数字。
【括展】：类似句式:
It is believed that…意为“人们认为……”, 其后同样接完整的句子。
e.g.: It is believed that tea was brought to Korea and Japan during the 6th and 7th centuries.
人们认为，茶在六至七世纪传到了朝鲜和日本。
13、被动语态
一般过去时被动语态形式：be(was/were)+done（动词过去分词）.
否定形式: wasn't/weren't done.
疑问句形式：Wasn't/Weren't+主语+done...
（was是am和is的过去式，were是are的过去式）
【括展】：一般过去时的主动语态与被动语态比较
e.g.: Alexandar Graham Bell invented the telephone in 1876. （一般过去时主动语态）
亚历山大.格雷厄姆.贝尔 1876年发明了电话。
The telephone was invented (by Alexander Graham Bell) in 1876.（一般过去时被动语态） 电话是由亚历山大.格雷厄姆.贝尔1876年发明的。
【点拨】："sb did sth..."是主动形式的表达；
其被动形式则是："sth was done (by sb)..."
【总结】：将动作的承受者变为动作的执行者，句子的时态不变，将助动词改成be动词+动词的过去分词。

My wife and I spent the day 5 the terrible pictures over again． When I watched family members looking for 6 loved ones, I would never forget the pain in their eyes． I couldn't understand how this could have happened．

III、阅读理解 (本大题有5小题，每小题2分，共10分)
Lake Victoria (维多利亚湖) is the largest lake in Africa．It is also the second largest lake in the world．It is an important lake because it is one of the sources (源头) for the longest river in the world, the Nile River．Lake Victoria provides a source of water, food, and power for several African countries．Lake Victoria is a big part of African life．
Unluckily, Lake Victoria has a problem．It is shrinking．There are several power stations at Lake Victoria in Uganda．These are on the Nile River, and besides producing power, they keep the water of the lake at a certain level．For the past forty years, that level has been 11. 9 meters．Over the last several years, the water level has dropped by about 2. 5 meters．There seem to be several reasons for this drop．
One possible reason is drought (干旱)．Drought has been very bad in the area since 2000．Lake Victoria gets all of its water from rain, so the drought means less water in the lake．
However, some environmentalists believe that the real problem is the power plants on Lake Victoria．Uganda depends on those power plants for most of its power, and they made the power plants larger in 2000．Many people believe the power plants have been taking too much water off Lake Victoria．As a result, they have been asked to use less water until Lake Victoria goes back to its old level．
Whether the low water level is caused by drought or power plants, the result is the same．This is already a poor area of Africa, where many people live a really hard life．People, animals and plants around Lake Victoria will suffer even more from low water levels on the lake．Many people need Lake Victoria for fishing or growing food．Fish need the water to live, and animals need it for water．Plants around the lake will die without the water, and then more animals and people will suffer．Unless the lake fills soon, many people will suffer and die．
(　　)21.Lake Victoria is __________．
A. an important lake in Africa.
B. the largest lake in the world．
C. the source of water, food and power for America．
D. the only source for the Nile River．
(　　)22.W hat does the underlined sentence “It is shrinking” most probably mean
A. It is becoming larger． B. It is becoming more beautiful．
C. It is becoming smaller． D. It is becoming more useful．
(　　)23.The water level of Lake Victoria is now __________．
A. 2.5 meters B. 11.9 meters C. 14.4 meters D. 9.4 meters
(　　)24.Which of the following is NOT true according to the passage
A. Rain water is the only source for the lake．
B. There has been little rain in the lake area since 2000．
C. The power plants in Uganda provide water for the lake．
D. Many people around Lake Victoria live a hard life because of low water levels of the lake．
(　　)25.According to the passage, how can we solve the problems around Lake Victoria
A. People must build more power plants．
B. More sources of water must be found．
C. Every country should offer some money to Africa．
D. All the people living in the area should move to another place．
