It’s great fun to explore new places ? it feels like an adventure, even when you know you’re not the first to have been there. But make sure not to get lost or waste time going round in circles.
●Do the map reading if you’re being driven somewhere. It’ll be easier if you keep turning the map so it follows the direction you’re traveling in. keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you’ll have to move to the back seat.
●Get a group of friends together and go exploring. You’ll need a good map, a compass (指南针) a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies (应急现金). Tell someone where you’re going before you set out and let them know what time you expect to be back. The test is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.
●See if your school or a club organizes orienteering activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B (and B to C etc) in the fastest time, or simply as spare?time activity. Either way, it’s not only good fun, but a great way to keep fit.

Children have their own rules in playing games. They seldom need a referee(裁判) and rarely trouble to keep scores. They don’t care much about who wins or loses, and it doesn’t seem to worry them if the game is not finished. Yet, they like games that depend a lot on luck, so that their personal abilities cannot be directly compared. They also enjoy games that move in stages, in which each stage, the choosing of leaders, the picking-up of sides, or the determining of which side shall start, is almost a game in itself.
Grown-ups can hardly find children’s games exciting, and they often feel puzzled at why their kids play such simple games again and again. However, it is found that a child plays games for very important reasons. He can be a good player without having to think whether he is a popular person, and he can find himself being a useful partner to someone of whom he is ordinarily afraid. He becomes a leader when it comes to his turn. He can be confident, too, in particular games, that it is his place to give orders, to pretend to be dead, to throw a ball actually at someone, or to kiss someone he has caught.
It appears to us that when children play a game they imagine a situation under their control. Everyone knows the rules, and more importantly, everyone plays according to the rules. Those rules may be childish, but they make sure that every child has a chance to win.
59．What is true about children when they play games?
A．They can stop playing any time they like.
B．They can test their personal abilities.
C．They want to pick a better team.
D．They don’t need rules.
60．To become a leader in a game the child has to .
A．play well
B．wait for his turn
C．be confident in himself
D．be popular among his playmates
61．Why does a child like playing games?
A．Because he can be someone other than himself.
B．Because he can become popular among friends.
C．Because he finds he is always lucky in games.
D．Because he likes the place where he plays a game.
62．The writer believes that .
A．children should make better rules for their games.
B．children should invite grown-ups to play with them.
C．children’s games can do them a lot of good
D．children play games without reasons
【C】
Most rain forests lie to the equator(赤道), where the climate is often mild and there are long hours of sunshine．The warmth of the land heats the air above, causing it to rise and tiny drops of water to fall as rain．The rainfall can reach at least 98 inches a year．This wet, warm world with plenty of sunlight is perfect for plants to grow, so the trees grow fast with green leaves all the year round．The trees themselves also have an effect on the climate．They gather water from the soil and pass it out into the air through their leaves．The wet air then forms clouds, which hang over the treetops like smoke．These clouds protect the forest from the daytime heat and night-time cold of nearby deserts, keeping temperatures fit for plant growth．
Rain forests slightly farther away from the equator remain just as warm, but they have a dry season of three months or more when little rain falls．Tree leaves fall during this dry season and new leaves grow when the wet season or monsoon(雨季) begins．Thus these areas are known as the "monsoon forest"．
Another type of rain forest grows on tropical mountains．It is often called the "cloud forest" because clouds often hang over the trees like fog．
The rain forest is the ideal place for the growth of many different trees．Most of them depend on animals to eat their fruits and spread their seeds．When the fruits are eaten, the seeds inside them go undamaged through animals' stomachs and are passed out in their droppings．The seeds lying on the forest floor then grow into new trees．
63．The climate of the rain forests near the equator is ________．
A．mild, wet and windy
B．hot, rainy and foggy
C．hot, wet and cloudy
D．warm, wet and sunny
64．We can learn from the passage that ________．
A．tree leaves are green all the time in the monsoon forest
B．there is a dry season in the cloud forest on tropical mountains
C．clouds help the plants in the rain forests near the deserts to grow
D．the formation of climate in the rain forest has little to do with the trees
65．According to the passage, ________ play the most important role in the spreading of seeds．
A．animals
B．droppings
C．fruits
D．winds
66．This passage is most likely to be found in _________．
A．a travel guide
B．a story book
C．a technical report
D．a geographical book
【D】
Indian’s snake charmers are to be retrained as wildlife teachers under a plan to prevent their unique skills and knowledge from being lost. The charmers, who make snakes dance to the sound of flutes(笛子), used to be a traditional feature of Indian life, performing in towns and villages, until they were banned in 1972 to control the trade in snake skins.
The government is now considering a plan to train the saperas, as they are known, to visit schools and zoos to tell children about forests and wildlife. There is also a proposal to set up a “dial a snake charmer” service to help householders to deal with unwelcome intruders (不速之客).
“For generations they have been a feature of Indian life but now they can't earn a living for fear of arrest,” said Behar Dutt, a conservationist behind the plans, “if a policeman doesn’t catch them, animal rights activists report them.”
Many snake charmers have continued to work clandestinely since the ban, despite the threat of up to three years in prison. But their trademark cloth-covered baskets, hung from a bamboo pole carried across their shoulders, make them an easy target for police.
The fate of Shisha Nath, 56, from Badarpur, a village just outside of Delhi, is typical of practitioners(从业者) of the dying art. “I used to earn enough to support my family and send my children to school, "he said. "Now it's hard to earn even f, 1 a day. My children want to be snake charmers. It’s our identity. We love the work. But it s become impossible.
Next month Dutt’s project to train 30 snake charmers will begin at a snake park in Pune, western India, where experts will enrich their home-grown skills with some formal knowledge.
More than the law, though, it is the dishonest attitude of their fellow countryman that angers many snake charmers.
"'We're disturbed all the time but when people want a snake removed from the house, they rush to us," said Prakash Nath, who was ordered recently to the home of Sonia Gandhi, the Congress party leader.
67. According to the passage, snake charmers will be retrained as wildlife teachers mainly because______.
A. schools need large numbers of such teachers
B. most of them cannot support their families
C. their performances on the street are banned
D. the government plans to save the dying art
68. The purpose of the proposed "dial a snake charmer" telephone service is ______.
A. to give performance of snake dancing
B. to teach householders how to catch and kill snakes
C. to offer cleaning service to wealthy householders
D. to help remove unwanted snakes from the houses
69. The word "clandestinely" in paragraph 4 can be best replaced by the word "_______"
A. secretly
B. publicly
C. attentively
D. diligently
70. Which of the following statements is NOT true according to the passage?
A. Snake charmers can easily be recognized by the police on the street.
B. Children of snake charmers would not like to continue their fathers' job.
C. Snake charmers are quite angry with the attitude of their fellow countrymen.
D. The animal rights activists take a negative attitude towards snake charmers.

What do you usually use your cell-phone for? Calling friends or sending them text messages?
As technology develops, nowadays cell-phones can do much more than that. They have become an all-in-one device.
A typical example is Apple’s Phone. The touch-screen cell-phone plays music, connects to the Web, sends e-mail and takes photos. More than 1 million Apple’s Phones have been sold since it was launched in June.
“Today’s young people enjoy using all kinds of digital
functions, such as those of a music player, a camera and even a computer,
constantly. An all-in-one device is easy to carry. That is the goal of
developing a technology to make our lives more convenient, simple and relaxed,”
said Professor Ding Shouqian at
However, the all-in-one cell-phones come with some problems. Users have complained that they are too complicated to use, and that their battery life is too short. Cell-phone producers say that they are working hard to make their phones even better.
It’s very convenient to use it. “We are trying to make the cell-phones in a way that people can quickly move from phoning to taking pictures and listening to music,” said Alastair Curtis, Nokia’s chief designer. “If you look at the Nokia 3250 model, it has a twisting bottom. So you twist it half a turn, and it’s in camera mode. You twist it another 90 degrees, and the alpha-numeric(字母和数字的) keys have disappeared and the music keys are there.” Japanese companies such as Toshiba and Fujitsu are also working to develop a new battery for mobile phone.
If all the problems are solved in the future, all-in-one phones will change our lives for the better.

Dear editor,
Recently we’ve conducted a survey on whether to support migrant workers in their moving to cities. Here is a brief report about it.
On one hand, migrant workers do play a very important role in the development of cities. They are actively involved in various kinds of jobs. In particular, they just do jobs such as cleaning, babysitting, and building, which are usually tiring, dirty even dangerous to their health and life. But these jobs are necessary and basic.
On the other hand, with more and more migrant workers coming in, the city is becoming more and more crowded. Also, the transport is much busier than before. To make matters worse, some of them don’t pay much attention to the cleanness and like littering everywhere, making the streets very dirty. The worst of all is that some even turn thieves if they cannot find any suitable jobs.
As far as I’m concerned, migrant workers have made great contributions to the development of big cities. Without them, we won’t have so many high-rise buildings. But if they can be well educated, it will be better for all of us.
Yours truly,
Jack
