Earth is the third planet from the sun. It is one of the four inner planets. The other three inner planets are Mercury, Venus, and Mars. The inner planets are also called the rocky planets, because they are made of rocks.
Earth is often called the “Water Planet”, because it is the only planet in our solar system which has liquid water on its surface. About 70% of the surface of Earth is covered by water! The other part of Earth is made up of continents and islands which have different landforms on them. Examples of landforms are mountains and plains. Plants and animals can live on Earth, because it has so much water.
Earth spins very quickly compared to other planets. It only takes Earth 24 hours to spin around its axis one time. One Earth day is 24 hours long! Earth orbits the sun in 365 days! This makes one Earth year 365 days long!
Earth is the only planet in our solar system where humans, other animals, and plants can live. There is plenty of water to drink or to live in. Water is present on Earth in its big oceans and in the air! Clouds are made of water vapor. The atmosphere has a lot of oxygen in it for animals to breathe, but the rest of our “air” is made up of water vapor, nitrogen, carbon dioxide, and other gases. The air is perfect for plants to grow. Earth temperature is not the same in all places, but the temperature is just right for plants, animals, and humans in most places on Earth.
Like the other inner planets, Earth has volcanoes. Volcanoes on Earth are different from those on other planets, because they still erupt. Scientists think that there may be active volcanoes on other planets and moons in our solar system, but they are still studying this.
Earth has one planet which we call the Moon. The surface of the Moon has many craters on it These were caused when meteorites hit it. It has many volcanoes on it which do not erupt anymore. We can see the moon at night without using a telescope. It is the closest space object to our planet ,Earth.
68.Earth is called the Water Planet,______.
A. because animals need water         B. the water makes it look blue from space
C. it has liquid water on its surface      D. Earth is the third planet from the sun
69. It takes Earth ______to orbit the sun in one year.
A.24 hours                   B.24 days                     C.365 days                   D.360 days
70. Life exists on Earth,______.
A. because the water, air, and temperature are just right
B. there is water vapor in clouds
C. Earth is the planet closest to the sun
D. earth has volcanoes
71.The craters on the moon were caused by______.
A. meteorites hitting its surface              B. active volcanoes
C. volcanoes which do not erupt anymore      D. some reasons that are not mentioned

It was a cold grey day in late November. The weather had changed overnight, when a backing wind brought a pale sky and a muzzling rain with it, and although it was now only a little after two o’clock in the afternoon the gray of a winter evening seemed to have closed upon the hills, surrounding them in mist. It would be dark by four. The leather seats felt damp to the hands, and there must have been a small crack in the roof, because now and again little drips of rain fell softly through, polluting the leather and leaving a dark – blue stain like a spot of ink. The wind came in, at times shaking the coach as it traveled round the bend of the road, and in the exposed places on the high ground it blew with such force that the whole body of the coach trembled and swayed, rocking between the high wheels like a drunken man.
The driver, muffled （裹�。� in a greatcoat to his ears, bent almost double in his seat in a faint endeavor to gain shelter from his own shoulders. The few passengers pressed together for warmth, exclaiming all together when the coach sank into a heavier rut （車(chē)轍） than usual, and one old fellow, who had kept up a constant complaint ever since he had joined the coach at Truro, rose from his seat in anger; and, feeling with the window – frame, let the window down with a crash, bringing a shower of rain upon himself and his fellow – passengers. He thrust his head out and shouted up to the driver, scolding him in a angry voice for a rogue and a murderer; that they would all be dead before they reached Bodmin if he persisted in driving at dangerous speed; they had no breath left in their bodies as it was, and he would never travel by coach again.
41．What is the main image the author gives in this description?
A．In terrible weather, a coach was running fast in mud with complaining passengers on it.
B．On a cold and rainy day the coach broke and the driver was repairing it on the road.
C．On a cold night the driver and the passengers felt very cold and struggled in the rain.
D．The bad condition of the road resulted in the bad mood of the passengers.
42．Which of the following is correct according to the text?
A．The windows were tightly closed, so the cold air was kept outside the coach.
B．The spot of ink stained leather, so the seats felt damp to the hands.
C．Most probably the roof of the coach was broken.
D．There was a drunken man swaying constantly on the coach.
43．The expression “muffled in a greatcoat to… his own shoulders” implies         .
A．the driver felt very cold and tried to change his seat
B．the driver felt comfortable by doing in that way
C．The driver felt very cold and tried to gain warmth
D．The driver tried to protect his ears and shoulders
44．We can learn from the text that         .
A．the coach was running slowly due to the bad weather
B．a(chǎn)n old passenger who got on the coach at Truro was angry about the windows
C．one of the passengers on the coach was a murderer

At first, the earth’s surface layer (層 ) was made up of huge blocks of hard, solid rocks.There slowly, the rocks broke up into smaller and smaller pieces. Finally stones, pebble(卵石) and grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remain mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil.
There are many ways in which large pieces of rock break into smaller ones. Wind, water, heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layer of the rock are slowly worn away. These leave holes and crack(裂縫) in the rock, which become bigger and finally the rock breaks up into smaller pieces.
The moving water of streams and rivers also help to break up rocks. As the water moves along, it carries with it small pieces of rock. These rub the larger ones, Thus, the larger rocks are worn down to smaller pieces.
The heat of the sun also help to breaking up rocks. When the sun shines, the rocks become very hot. If these rocks are suddenly cooled, they may crack. Ice also plays a part in making soil.  Water in the cracks can turn into ice in cold weather. As this happens, it becomes bigger and cracks become wider, and finally break into smaller pieces.

Have you ever heard your own voice? “Of course,” you say.
Has anyone else ever heard your voice? Again you say, “Of course.”
But that’s not quite true. Nobody else has ever heard your voice-the way you hear it. When you talk, you set up sound waves The air outside your head carries the sound waves to your outer ears. But, of course, the sound of your voice begins inside your head. The bones of your head pick up the sound waves, too. They carry the sound waves straight to your inner ears. You get the sound from the outside and the inside too. Other people get just the sound waves from the outside. That is why they don’t hear your voice the way you do.

C
A car needs gas to run as your body needs food to work for you. Eating the right kinds of food is very important. A good eating habit can help your body grow strong if you take care of what you eat.
There are four main food groups altogether. The dairy group has food like milk, cheese and sour milk. The other three groups are the meat and fish group, the fruit and vegetable group, and the bread and rice group. Each meal should have at least one food from all four main groups. With all of these foods together, you will be given enough energy during the day.
It is easy to get into bad eating habits. You may eat your breakfast in a hurry to get to school on time or you may not have time for a good lunch. It may be easier to eat fish and chips for your supper all the time. But you will find yourself tired and you will not be able to think quickly.
Watching what you eat will help keep your body healthy and strong. It is also good to take some exercise. It will help you eat more if you take a walk or play games in the open air. Having good eating habits with some exercise is the key to your health.

E
The earth is getting warmer. The planet is suffering. But what can you do about it? Reduce the amount of waste you generate. Use cleaner energy sources and go greener today, starting with these steps:
1. Get a reusable water bottle
Americans buy about 25 billion single-serving plastic water bottles each year. That's an average of 83 bottles per person per year. Plastic bottles take plenty of resources to produce, including fuel for transportation and petroleum to make the plastic. Even recycling bottles uses energy.
2. Eat less meat
You don't need to become a vegetarian to help save the planet. Eating meat just one day less a week can reduce your negative impact on the environment. More water, energy and land are required to produce meat than to produce grain.
3. Switch to energy-efficient light bulbs
Most households use standard incandescent (白熾的) bulbs. But compact fluorescent (熒光的) light bulbs, or CFLs, use 66 percent less energy than standard bulbs, produce just as much light, last up to 10 times longer and don't need to be replaced as often. If every household in the United States replaced just one incandescent light bulb with a CFL bulb, it would equal removing one million cars from the road.
4. Buy organic and local food
Did you know that only 1 percent of pesticides (殺蟲(chóng)劑) applied to crops reach the pests they target? The rest enter the environment. Organic food is grown without the use of pesticides. Organic farming can use 50 percent less energy than traditional farming methods. Buying local food saves on the fuel used to transport food grown elsewhere, thousands of miles across the country or around the world.
5. Recycle your electronics
Everyone knows the importance of recycling glass and plastic, but what about cell phones, computers, CDs and batteries? Electronics are responsible for about 40 percent of toxic (有毒的) heavy metals such as lead and mercury. Check with your city's recycling facilities to see if they take electronics.
72. The readers of this passage are called on to ______.
A. help reduce global warming               B. use water in a wise way               C. donate money for charity                      D. keep a balanced diet
73. What is an advantage of CFLs according to the passage?
A. They use more energy but produce more light.                                   B. They can last longer so don't need to be replaced often.                                        C. They cost less than standard incandescent bulbs.                                         D. They are as energy-efficient as incandescent bulbs.
74. Which of the following figures is correct according to the passage?
A. Every year an American buys 63 plastic water bottles on average.                   B. Eating meat one day less a week helps cut environment costs.                                   C. 99 of the pesticides used on crops is effective in practice.                                         D. Electronics account for half of poisonous heavy metals on the earth.
75. Which can be the best title for this passage?
A. Why is the earth getting warmer?           B. What can we do about pollution?              C. How can you lead a greener life?          D. Who is to blame for global warming?

       Whether you're heading into the wild or down the road, it's hard to find a better electronic sidekick than a GPS. (Well, you know, other than a cell phone.)
Because a GPS has to receive a signal from space, physical impediments(遮擋) like skyscrapers, cliff faces, and even trees can stump(阻斷) it. Reception is less of an issue with the ultrasensitive(超靈敏) chipsets in newer models, but if the walls are closing in on you, take a tip from a time when navigation systems weren't the streamlined panels they are today: Hooking up an antenna(天線) will make use of even the most tenuous celestial connection. There's a port on the back of most GPS devices for jacking in.
You'll also want to remember that a GPS is not a compass: It runs on software. Like your PC, it needs to communicate with the mother ship periodically. Vendors(供應(yīng)商) refresh firmware and maps on a regular basis, sometimes even daily. These updates deliver new bits of data that significantly affect your gadget's accuracy. But if you live in the boonies(郊區(qū)) on a road named after your sister-wife, don't expect NavTeq to come a-knocking with its survey equipment. Fortunately, most companies make it easy to update your own maps. Usually it's as simple as plugging into your home computer, dropping a couple of pins in Google Maps, and clicking Save.
If you own a new Tom Tom, it's even easier. You can edit maps on the unit itself, though you might not have to: Some of the company's navigation updates themselves. Tom Tom's IQ Routes software takes data from every person who uses the company' gadgets and readjusts its assumptions about which roads you should use and how long a given route will take. It will even change its own maps.
See, it's not that hard: Your GPS may use NASA technology, but getting the most out of it isn't rocket science.
46. The writer thinks the useful electronic partner is __  
____besides a cell phone when driving outdoors.
A. a GPS            B. Tom Tom's IQ Routes              C. a PC       D. NASA
47. Which statement is NOT true about a GPS according to the passage?
A. It receives a signal from space.
B. It is not a compass.
C. It needs to refresh its information.
D. It has no port to connect other equipment.
48. You may learn from the passage that Tom Tom (Para 4) is _______.
A. a GPS receiver
B. a device that can be used to edit maps
C. a device that can be used to update software
D. a person who readjusts GPS assumptions
49. The main idea of the last paragraph is _______.
A. that we should make the most of GPS in rocket science
B. that getting the most out of GPS is too difficult
C. getting the most out of GPS is very easy
D. GPS owns NASA technology
50. Which is not mentioned about a GPS according to the passage?
A. Its usage.          B. Its price and shape.   C. Its technology.     D. Its benefit.
