二、11.±3;12.13;13.O 14.2;15.67或-61;16.借助计算器可得:1121314153,所以至少取5个数.;17.3 18.7;19.-1,0,1;20.111111111
三、21.(1)2335;(2)5322.(1)1-x=±8,解得x=-7或9;(2)2x-1=2, 解得x=3 223.(1)因为2x-1=36,2x+y-1=25,所以2x=37,3y=-33, 所以2x-3y+11=81,所以81的平方根为±9(2)2a+3+1-3a=0,解得a=4,所以x=16,y=64,所以x+y=80.24.设第二个正方体的棱长为x,则x=127+6,所以x=343,所以x=3343=7.3
3325.设a=2x,b=x,c=3x,因为abc=25,所以2x·x·3x=25, 所以x=325,所以x≈1.609.6
222所以长方体的表面积为(2x+6x+3x)≈57.0 26.因为x是1的平方根,所以x=±1, 当x=1时,原式=1000,其立方根为10;当x=-1时,原式=-1000,其立方根为-10.27.(1)点B坐标是(35,5);(2)向左平移5个单位长度后,各点的纵坐标不变,横坐标都减少5,所以A′(O, 5)、B′(25,5)、C′(5,0),O′(-5,0).(3)平行四边形的面积为25·5=2(5)=2×5=10.

(1)如:艨艟列队从容呈五阵之势,水兵技艺精湛显英豪之勇。(2)提示:画面能表现钱塘潮之雄伟壮观即可。(3)提示:描绘场面应加入自己的想像,描述语言应生动形象,能运用一些修辞手法。15. (1)同“缺”,断开、中断(2)这里指飞奔的马。16. 在极高的山峰上,生长着许多奇形怪状的柏树;在山峰之间,常有悬泉瀑布飞流冲荡。17. (1)三峡概貌四季特点(2)连绵不断 遮天蔽日至于夏水襄陵,沿溯阻绝。(3)既能提示水流急速的原因,又能使急流和峻岭相互映衬水以夏季为盛18. 引用渔歌既是对秋景的总结,又能引起人缠绵的愁思。19. 瞿塘峡、巫峡、西陵峡;三峡水利工程(三峡工程);大江截流,百万移民,奉节古城爆破,下闸蓄水、船闸试通航,几台机组相继并网发电等。(说出三件即可)20. “中书”是官职名,第二个“书”是书信的意思。21. ①交相。②消散22. ①夕阳快要落山了,潜藏在水中的鱼争相跳出水面。②这实在是人间天堂。23.

21.A 根据上下文,此句应意为“我不想听任何借口”,故选hear。
22.B for表示目的,exercise在这里作名词用。
23.C 从上文得知“你不经常锻炼就会变胖”,get fat“变胖”。
24.D a few修饰可数名词复数,表示肯定意义,而few修饰可数名词复数,表示否定意义,little和a little修饰不可数名词,故选D。

六、阅读理解 从 A、B、C、D中选出最佳答案。(5分)
“An apple a day keeps the doctor away.” Well, milk may work in the same way!
Milk is the natural food for mammalian(哺乳动物) babies. It helps them grow strong because it is rich in protein(蛋白质), calcium(钙) and vitamins. Milk can also help you sleep better because it calms you down.
But remember to drink milk with care. Find out how old the milk is. Make sure it is fresh and hasn’t gone bad. Don’t drink milk when your stomach is empty. Eat some bread or corn at the same time. That’ll help you take in more protein and vitamins.
Doctors say teens need at least 500ml of milk a day. That’s two or three cups. Milk-drinking started long ago, as early as 6,000-8,000BC. At that time people started to keep cows, sheep and goats to get their milk. Of course what you drink today isn’t that fresh from the cow. People cool the fresh milk down to 40C to stop the bacteria(细菌)growing. In factories, milk is pasteurized(灭菌) to stop it growing bad. After disinfections(消毒) and packaging, it goes to the supermarkets.
Yoghourt also comes from milk. People make some special bacteria to change the taste of milk and make the nutrients(营养) in it easier for people to take in. Maybe that’s why it’s getting more popular with people!
61. Milk helps people grow strong because it is rich in ________.
A. Calcium B. protein
C. vitamins D. A, B and C
62. The sentence “An apple a day keeps the doctor away.” tells us that________.
A .the doctor likes to eat apples every day
B. the doctor doesn’t like apples at all
C. the doctor eats an apple each day
D. apples are good for our health
63. When you drink milk , you’d better________.
A. find out when the milk was produced
B. make sure it’s fresh and hasn’t gone bad
C. not drink milk when your stomach is empty
D. do all of the above
64. Why is it better to eat some bread or corn while drinking milk ?
A. Our body can take in more protein and vitamins in this way.
B. That’ll help us grow taller and stronger.
C. That’ll help us taste milk better.
D. We’ll still feel hungry without eating some bread or corn.
65. Which of the following statements is true ?
A. One cup of milk is good enough for teens each day.
B. Drinking milk is likely to make teens sleepy.
C. To stop the bacteria growing , people cool the fresh milk down to 40C.
D. Yoghourt is one kind of milk which has gone bad
