Motorists used to listening to the radio or their favorite tunes on CDs may have a new way to entertain themselves, after engineers in Japan developed a musical road surface.
The Hokkaido Industrial Research Institute has built a number of “melody roads”, which use cars as tuning forks to play music as they travel.
The concept works by using grooves(凹槽). They are cut at very specific intervals(間隔) in the road surface. The melody road uses the spaces between to create different notes(音符).
Depending on how far apart the grooves are, a car moving over them will produce a series of high or low notes, and designers are able to create a distinct tune.
Patent documents for the design describe it as notches “formed in a road surface so as to play a melody without producing simple sound or rhythm and reproduce melody-like tones”.
There are three musical roads in central and northern Japan---one of which plays the tune of a Japanese pop song. Reports say the system was invented by Shizuo Shinoda. He scraped some markings into a road with a bulldozer(推土機) before driving over them and found that they helped to produce all kinds of tones.
The optimal speed for melody road is 44 kph, but people say it is not always easy to get the intended sound.
“You need to keep the car windows closed to hear well,” wrote one Japanese blogger. “Driving too fast will sound like playing fast forward, while driving around 12 mph (20 kph) has a slow-motion effect, making you almost car-sick.”
59. According to the passage, to create different notes, melody roads use ______.
A. cars    B. grooves    C. spaces between internals    D. bulldozers
60. We can learn from the passage that the highness of notes is dependent on ______.
A. how far the grooves are                B. how big the grooves are
C. the number of the grooves              D. the speed of the car
61. The underlined word “optimal” in the passage might mean ______.
A. fastest      B. possible      C. best     D. suitable
62. In order to hear the music well, you have to ______.
A. drive very fast                       B. drive slowly
C. open the window wide                D. keep the window closed

SINGAPORE - Singapore on Thursday stuck to its I8-year ban on the import and sale of chewing gum (口香糖), which has become an international symbol of the city-state's image as a strict society.                                     
"The government stands by its decision to ban chewing gum. Chewing gum has not been a significant problem since that ban took effect, there have been concerns that lifting the ban on chewing gum could result in chewing gum litter and weaken ongoing efforts to control littering." Maliki Osman, parliamentary secretary at the Ministry of National Development, told parliament.
Osman said as the reason for the imposition (強迫接受) of the ban is still suitable,  "the government's position is that the ban shall remain." He was responding to a question in parliament from Denise Phua, a fellow member of the ruling People's Action Party who argued that the ban had been used to criticize its tough governance laws.
"I think this ban ... now needs a re-thinking. Surely Singapore will not consider banning sweets because of sweet wrapper litter or ice-cream stick litter," she said.
Singapore, known worldwide for its high-quality clean image, banned the import and sale of chewing gum in 1992 in a bid to cope with the problem of people sticking the gum on chairs, tables, lifts and other public areas.
One of the key reasons for the ban had been the disturbance of services on Singapore's subway train system because of chewing gum being stuck on the doors and causing delays. Singapore partially lifted the ban in 2004 by allowing the sale of chewing gum used for health reasons, such as dental health gum, after the conclusion of a US-Singapore Free Trade Agreement.
Australian tourist Hazel Lane, 48, said keeping the ban on chewing gum was sure Singaporeans wouldn't want to spoil their "ridiculous" and she told AFP that she's own environment and their own image. Angel Wong, 34, a tourist from Hong Kong, however, welcomed the news. She said,  "I come from a country that doesn't have the ban and there's always chewing gum all over the floor, To me the ban doesn't change my image of Singapore so it’s a good thing because it keeps the environment clean."
1. The ban on the import and sale of chewing gum was started in 1992 ______.
A. when people began to buy the gum everywhere
B. to bid to stop people sticking the gum in the public
C. because the gum delayed the subway
D. when the country was in a bid to show its city-state's clean image
2. What can we learn about the ban according to Maliki Osman?
A. The government will keep it ongoing forever.
B. It will lead to littering the chewing gum everywhere.
C. More and more concerns about the ban will make chewing gum out of control
D. Banning chewing gum is still one of the important jobs of the government now.
3. According to what Denise Phua said in paragraph 4, we can know that she ______.
A. would say yes to the ban
B. would think more about the ban again
C. would like the government to take the ban on second thought
     D. argued that the ban should be cancelled
4. It can be inferred from the passage that ______.
A. whether the ban needs changing or not has become a problem to be discussed
B. Singapore's subway train system was delayed by chewing gum
C. chewing gum will soon be banned in many countries
D. only the ban has led to the friendly environment in Singapore
5. What's the main idea of the last paragraph?
A. There is such a ban in China and Australia.
B. Different people have their own ideas about the ban.
C. The ban is either welcomed by China or by Australia.
D. The ban does good to keep the environment clean.

   Life on land probably began about 430 million years ago, though it has stayed in the water for perhaps as much as 3,000 million years. When we think of the first thing on land, we probably think of strange animals coming out of the oceans, but in fact no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessity, since then, the plants, are the only form of life that is able to get and store energy.
  The first plants to stay out of the water were probably certain kinds of algae(海藻)which were followed by other plants that grew close to the ground and needed water in which to reproduce. Once the move to land had been made, however, evolution(進化)happened quickly. By the end of 100 million years, plants had developed their roots(根), and some had got tree -like forms since height was very important in gaining sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modern trees. They had roots, leaves, wood, but mostly they had not developed seeds.
59.The main idea of the first paragraph is ________.
  A. life on land probably began 430 years ago
  B. the first animal on land came from oceans
  C. there wouldn't have been animals without plants
  D. plants are the only form of life that is able to get and store energy
60.Which of the following statements is true according to the passage?
  A. Algae probably has stayed for more than 430 million years.
  B. It is impossible that algae might be the earliest plant on land.
  C. Plants get food from animals in the oceans.
  D. Evolution began after animals appeared on land.
61.Plants with roots appeared about ________ million years ago.
  A. 430     B. 300      C. 330      D. 100
62.According to the passage, ________ appeared earlier than ________.
  A. apples; oranges         B. oranges; apples

C
Not many years ago, some American farmers began to complain about hawks(鷹). The hawks were killing chickens. The farmers did not know what to do. They went to the government officials and asked for help.
The officials said, “ We’ll pay you for each hawk you kill.” The farmers began to kill the hawks. Many hawks were killed, but the farmers now had another problem. The field mice were growing in number and they were eating up the farmers’ corn. Hawks eat not only chickens but also field mice. They eat more field mice than chickens. But if the farmers had known that, they would not have upset(打亂) the balance of nature. In one part of the USA, there are deer which eat a kind of wild rose. The deer are eaten by mountain lions. The number of deer, mountain lions, and wild rose does not change much if people stay away from them. If there are too many deer, mountain lions will increase rapidly in number and kill many deer. If there are too many mountain lions, there will be fewer deer and there will be more roses.
It is always necessary for us to keep the balance of nature. The government once killed almost all the mountain lions to protect the deer. Soon there were so many deer that they ate up all the wild roses. Then they began to eat the green leaves of young trees which were important to the farmers.
So the farmers protected their trees from the deer. The deer had nothing to eat, and many of them died.
The government learned a valuable lesson from nature.
44. What had happened after the hawks were killed?
A. People wouldn’t worry about their chickens.
B. The number of the field mice became too large.
C. The number of the field mice became small.
D. The field mice were eating up the farmers’ corn.
45. Why did American people have to protect their trees?
A. Because the mountain lions destroyed the trees.
B. Because there were so many deer that they began to eat the green leaves.
C. Because they wanted the trees to grow well.
D. Because the trees are more important than the deer.
46. What can we learn from the article?
A. We must keep the balance of nature.
B. We must not kill any animals.
C. we must feed the hawks with our corn to keep the balance of nature.
D. Both A and B.

How Do Animals Catch Their ZZZ’s?
Different creatures have developed some pretty creative ways to get their rest and stay safe. The lizard(蜥蝎)likes to sleep at the far end of small branches hanging out over a pond or lake in the rain forest. If a snake tries to slither up the branch to eat it ,it will shake the branch and knock the lizard off ,and the lizard will fall safely into the water. Chameleons can change color to match their surroundings in order to hide even while sleeping.
Corillas(大猩猩)like to sleep high in the trees. They build a new bed every night, sometimes taking up to half an hour to pile branches ,twigs ,and leaves into a comfortable bed .Birds also find it safe to sleep in the trees, but unless they have eggs or young chicks ,they don’t use a nest .They just lock their feet around a branch and hang on .A special tendon(腱)in their legs in automatically tight when they are at rest ,so they won’t let go and fall.
Dolphins live underwater ,but must come to the surface to breather .Scientists now believe that dolphins may sleep with only half their brain, while the other half stays awake to keep them safe and breathing. Seals also do this ,lying on their sides on the surface of the water with one flipper underwater paddling to keep their noses above the surface. Some ducks may also have this ability, and actually sleep with one eye closed and one eye open.                          
56.How many animals are mentioned in this passage?
A.6.                       B.7.                       C.8.                       D.9.
