水是宝贵的自然资源,是地球上一切生物赖以生存的物质之一。地球总水量约为14.1亿立方公里,但如此多的水中淡水只占3%,而且其中的87%被封闭在冰川、大气、地层中。20世纪以来,全球人口增长了3倍,经济增长了20倍,用水量增长了10倍。同时,由于生产和生活废水急增,而且不经处理直接排入水体,更加重了水资源匮乏这一全球性危机。
联合国教科文组织在97年把水资源定义为“可资利用或可能被利用的水源,即应当能够为满足生产生活用途而得以利用”,而《中国自然资源》将水资源定义为“能为人类生产生活直接利用的,在水循环过程中产生的地表、地下径流和由它们存留在陆地上可再生的水体”。
我国水资源总量约2.8万亿立方米,但人均占有量只排在世界第121位,是世界人均占有量的1/4。此外,我国水资源空间分布很不均匀,南多而北少。重经济发展而轻环境保护又导致许多地区出现严重的水体污染,因此,水资源问题也成了我国社会和经济发展中的重大问题。

答:_______________________________ ___ _
2、文中对“水资源”有两种定义,请指出它们的主要相同点和不同点。(2分)

3.A直奔 B奔跑 C投奔 D奔命 ( )
4.A哽咽 B吞咽 C咽下 D狼吞虎咽( )
二、下面书写全部正确的一组是( )(1分)

7.列方程解应用题──有趣的行程问题 答案
1.1或3 2.4.8 3.640
4.16
提示:设再过x分钟,分针与时针第一次重合,分针每分钟走6°,时针每分钟走0.5°, 则6x=0.5x+90+0.5×5,解得x=16 .
5.C 6.C 提示: 7.16
8.(1)设CE长为x千米,则1.6+1+x+1=2×(3-2×0.5),解得x=0.4(千米)
(2)若步行路线为A→D→C→B→E→A(或A→E→B→C→D→A)则所用时间为: (1.6+1+1.2+0.4+1)+3×0.5=4.1(小时);
若步行路线为A→D→C→E→B→E→A(•或A→E→B→E→C→D→A),
则所用时间为: (1.6+1+0.4+0.4×2+1)+3×0.5=3.9(小时),
因为4.1>4,4>3.9,
所以,步行路线应为A→D→C→E→B→E→A(或A→E→B→E→C→D→A).
9.提示:设此人从家里出发到火车开车的时间为x小时,

则体积为0.15axm3,盘上所缠绕的胶片的内、外半径分别为30mm和30+015×600=120(mm),其体积又可表示为 (120-30)•a=13500a(m3),
于是有0.15ax=13500a ,x=90000 ≈282600,胶片长约282600mm,即282.6mm.
11.100 提示:设原工作效率为a,工作总量为b,由 - =20,得 =100.
12.B 13.A
14.C 提示:设商品的进价为a元,标价为b元,

原标价出售的利润率为 ×100%=50%.
15.(1)(b-na)x+h
(2)由题意得 得a=2b,h=30b.
若6个泄洪闸同时打开,3小时后相对于警戒线的水面高度为(b-na)x+h=-3b<0.•
故该水库能在3个小时内使水位降至警戒线.
16.(1)设这批货物共有T吨,甲车每次运t甲吨,乙车每次运t乙吨,
则2a•t甲=a•t乙=T,•得t甲:t乙=1:2.
(2)由题意得: = , 由(1)知t乙=2t甲,
故 = 解得T=540.
甲车车主应得运费540× ×=20=2160(元),•
乙、•丙车主各得运费540•× ×20=4320(元).
9.线段 答案
1.2a+b 2.12 3.5a+8b+9c+8d+5e 4.D 5.C
6.A 提示:AQ+BC=2250>1996,所以A、P、Q、B四点位置如图所示:
7.MN>AB+NB 提示:MN=MA+AN= AB,AB+NB=AB+(CN-BC)= AB 8.MN=20或40
9.23或1 提示:分点Q在线段AP上与点Q在线段PB上两种情况讨论

30x+15(100-x)+10(300-x)=4500+5x>4500,又排除选项D.
16.(1)如图①,两条直线因其位置不同,可以分别把平面分成3个或4个区域;•如图②,三条直线因其位置关系的不同,可以分别把平面分成4个、6个和7个区域.
(2)如图③,四条直线最多可以把平面分成11个区域,•此时这四条直线位置关系是两两相交,且无三线共点.

Australia has a lot of lovely animals. You cannot find them anywhere else in the world. The most famous ones are kangaroos and koalas(树袋熊). The kangaroo is the symbol of Australia. They have large eyes and ears. They don’t walk, they jump. They use their strong back legs. They can jump at up to 74 kilometers per hour. They can go over nine meters in one jump!
Kangaroo mothers have pouches(育儿袋) to carry their babies. The babies stay inside to get milk and keep warm. Kangaroos are everywhere in Australia. They are on TV, in books and in the shops. The government even wants to put them on passports(护照).
But do you know that millions of kangaroos are killed every year? There are too many of them.
There are about 20 to 25 million kangaroos in Australia. That’s more than the number of people in the country! Some kangaroos go hungry because there is not enough food to eat. They break into farms for food. Farmers are very angry with them. The koala is another famous Australian animal. They look like bears, and have small eyes and big noses. They eat leaves from eucalyptus, where they spend most of their time. Koalas have a special smell. They use it to mark their home—“This is my place, you can’t come in!” Like kangaroos, a koala baby lives in its mother’s pouch. But koalas have fewer places to live in. There are about 100,000 koalas in Australia. There is a law to keep them safe.
( )41. Kangaroos and koalas are the most famous animals in Australia because _______.

( )44. What do koalas use to mark their home?

The size and shape of your ears show your character more than any other parts of the face. Other parts of the face change shape as we get older, but ears do not change their shape. They only change in size.
Reading people’s character from their ears is an old science. In very old times people thought that a person with big ears had a good and generous character. They thought that a person with pale (nearly white), small ears was dangerous. They also thought that the shape of the ear showed whether a person was musical or not. Today, too, many people believe that the size and the shape of the ear help you know if a person is musical.
Ears are all different, and each characteristic has a meaning. Next time when you look at a person, see if his ears are large or small. Look at the lobes( the lowest part of the ear). Are they attached(连着) to the face? Ears that are always red mean a person may easily get angry, or he/she just has high blood pressure(高血压). Ears that are always cold and pale mean a person has a nervous character. And a big inside hole of the ear means a person is musical.
( )46.In the old times people might ask for help from a person with_______.
A. red ears B. big ears C. small ears D. pale ears
( )47. The passage is mainly about _____.
A. the size of our ears B. musical ears
C. ears which related to characters D. our faces and ears
( ) 48. From the passage, we know ______ change shape as we get older.
A. ears B. hair C. eyes D. teeth
( ) 49. We can guess Beethoven may have _____.
A. pale ears B. white ears
C. small ears D. ears with a big inside hole
( )50. If you are often late for school, you may find the ears of your teacher _________.
A. get bigger B. get smaller C. get colder D. get redder
