Bamboo (竹子) is one of nature's (自然) most surprising plants. Many people call this plant a tree, but it is a kind of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist reported one bamboo plant which grew 1. 5 metres(4 feet) in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1, 000 kinds of bamboo.
Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimetres wide while others may grow to more than 30 centimetres (1 foot) across. This plant also comes in different colours, from yellow to black to green.
Bamboo has been used to make many things such as hats and kitchen tools( 厨房用具). Because it is strong, bamboo is also used to build buildings.
Many Asian countries have used bamboo for hundreds of years. They often use bamboo for buildings and supporting (支撑) new buildings and bridges while they are being built.
In Africa, poor farmers are taught how to find water using bamboo. These African countries need cheap way to find water because they have no money, and their fields often die from no rain and no water. Bamboo pipes( 管子) help poor farmers bring water to their thirsty fields without spending a lot of money. How is bamboo like grass?

Move as Millions，Survive as One
Great white sharks in the Pacific Ocean．Wildebeest in Africa．Arctic terns in the Atlantic．At first，these animals seem completely different．One swims，one walks，and the other flies．But they all have one thing in common．They all migrate．
Some migrating groups move to a place with a better temperature．Some go to find food or wather．The groups travel as one，trying to survive（生存）．During the trip，they face many different challenges．One challenge is distance．Some migrating animals take very long trips．They go far away from their home areas．For example，one great white shark swam from Australia to South African and back．In nine months，it swam about 20，000 kilometers．
Another chanllenge is finding enough food and water during the journey．For example，each Malielephant needs over 200 liters of water each day．To get this，they need to go from one waterhole to another．
In addition，migrating animals have to avoid other animals that want to eat them．For example，the zebra has to stay away from lions．Traveling as a group helps keep them safe．All the zebras in the group can watch for danger．When one zebra is in trouble，the other members make a circle around it．
By working as a group，migrating animals can survive some of the world's most extraordinary journeys．
21．The main idea of the first paragraph is that animals migrate．
A．not all kinds of
B．only similar
C．different kinds of
22．The meaning of the underlined word"migrate"means" "in Chinese．
A．奔跑
B．迁徙
C．追逐
23．The passage talks about big challenges for the animals．
A．two
B．three
C．four
24．Which of the following statements is NOT true？
A．It's about 20，000 kilometers from South Africa to Australia．
B．A Malt elephant needs more than 200 liters of water a day．
C．Zebras help each other when they are in trouble．
25．From the passage，we can infer（推断）that ．
A．lions may cat zebras

C．lions try to avoid zebras．
The Building That Moves
Everyone knows that buildings don't move．They can't change the way they look．However，architect（建筑师）David Fisher wants to change that．
Fisher has an amazing idea．He wants to make 80﹣story buildings that change shape．Each floor will move around slowly．The floors will move at different speeds．Because of this，the shape of the building is always changing．"These buildings will never look the same，"says Fisher．
His idea is an interesting one．However，Fisher doesn't stop there．He also wants the building to be"green"．The building will make its own energy．In most buildings，only the top floor has a roof（屋顶）．In Fisher's building，each floor will have its own roof．The roofs each have solar panels（太阳能板）．This means a lot more solar energy．Also，machines between each floor of the building will catch the wind．They will turn the wind into energy．
Fisher's ideas sound impossible．However，that's what people also said before humans traveled into space!
16．The passage is mainly talking about ．
A．buildings for the future
B．the life of an architect
C．how green buildings work
17．The underlined word"80﹣story"means the building has 80 ．
A．shapes
B．floors
C．different speeds
18．Fisher's building can make its own energy because the building ．
A．is tall and always moving
B．is tall and has many solar panels
C．is always moving and has many solar panels
19．The Fisher's building will NOT get energy from ．
A．the sun
B．the water
C．the wind
20．Why does the writer say"that's what people also said before humans traveled into space"？ _
A．To show why Fisher's building will never work．
B．To show why Fisher's building is like a spaceship．
C．To show that unusual ideas can sometimes work．
Some days，don't you think，"Wouldn't it be nice if the laundry would just do itself？"Self﹣cleaning clothes may sound crazy．But Australian researchers have found a way to make something like this possible!
A team at RMIT University in Melbourne，Australia，found a way to put special nanostructures （纳米结构） into clothing，which can then clean the clothes．When sunlight hits the nanostructures，they break down the dirt and stains （污渍） that don't belong on your clothes．
The nanostructures don't break down the actual clothing because cotton and the other clothing materials are too strong to be broken down．According to CNN，the researchers cover the clothing in a solution made of silver and copper （铜） nanostructures．All it takes is 40minutes of sunlight and your clothes will look as good as new．
So if you spill on yourself during lunch，you can step outside for a walk，and it will be clean by the time you go inside．It not only makes your life easier，but it can also be good for the environment．
According to the US Department of Energy，the average load of laundry uses about 25gallons （about 94liters） of water．Water is a very important resource，so using less of it to wash clothes is better for the environment．But one of the scientists at RMIT University knows more needs to be done．
"There's more work to do before we can start throwing out our washing machines，"said Dr Rajesh Ramanathan，"but this is a strong foundation （基础）．"
So what's the next step？Ramanathan wants to either start selling the solution by itself or convincing （说服） clothing makers to treat the clothing with the solution while clothes are being made．
57．How do the clothing with the nanostructures get cleaned？
A．Cotton clothes wash easily
B．This kind of clothing washes it by itself．
C．The dirt and stains are broken down in the sunlight．
D．Silver and copper help to get off the dirt in the dark．
58．What do Paragraphs 4﹣5talk about？
A．What advantages the self﹣cleaning clothes have．
B．How the self﹣cleaning clothes work．
C．How the self﹣cleaning clothes are made．
D．What helps the self﹣cleaning clothes work．
59．What does the underlined word"solution"in the last paragraph mean？
A．Machines
B．Clothes．
C．Silver．
D．Design．
60．What can we learn from the passage？
A．Silver and copper sell well．
B．The solution is not put into practice．
C．Clothing makes certainly like the solution．
D．We don't need washing machines any more．
A city without cars would be very strange，right？But Venice is such a city．
Venice is in the northeast of Italy．It wasn't built on land，like Beijing or Shanghai，but on more than 110islands．Seawater is everywhere around the city．
Even so，travel isn't difficult．The waterways have always been the best way to get around．There are 117waterways and more than 400bridges that can guide you where you want to go．People in Venice move from place to place by boat．
Water makes the city special，but it is also a big problem．Sometimes tourists will have such strange experiences．One moment they walk across the Rialto Bridge，and there's nothing special．But when they come back to the bridge an hour later，it's underwater and everyone is wearing rain shoes．
Once，people used too much underground water．This made the city get lower little by little．Now the city has gone down by 23centimeters．Another problem is the rising seawater．The temperature has risen over the years．This has made the ice of the Arctic Ocean （北冰洋） melt（ 融化）．Every year，high waters hit the city in autumn and winter．When a lot of water comes，more than half of the city is underwater．
Scientists are trying different ways to stop the city from getting even lower．The Italian government has asked some of Italy's biggest companies to build the MOST project，which was planned to be build under the seawater to stop the rising water．Anyway，this project is helping solve the problem．
53．Which is the best way to travel in Venice？
A．The waterways．
B．Taxis and cars．
C.400bridges
D．Boats and rain shoes．
54．What doesn't cause Venice to get lower and lower？

B．High waters won't hit Venice any more．
C．Scientists can solve the problems easily
D．Some possible ways help to solve the problem．
56．What's the best title of this passage？
