A. There will probably be no school on Mars.
B. It might take us two or three days to get to Mars.
C. There is a problem for us to live on Mars.
D. Food will not be the same.
E. First, people will have more space.
Many people believe that, by the year 2100, we will live on the planet Mars(火星). Here is what life could be like.
First of all, transport should be much better. By 2100, spaceship can travel at half the speed of light.  小題1: 
Secondly, humans need food, water and air to live. Scientists should be able to find plants that can grow on Mars. These plants will provide us with food and air.
 小題2:  We could easily jump too high and fly slowly away into space. To prevent this, humans on Mars have to wear special shoes to make themselves heavier.
Life on Mars will be better in many ways.  小題3:  It is possible to live in a large building with many bedrooms. Then, robot will do most of the work, so we have more time for hobbies.
 小題4: Every student can study, do their homework on the computer and take exams in online schools. Each student will also have their own online teacher called “e-teacher”.
However, in some ways, life on Mars may not be better than that on the earth today.  小題5:Meals will probably be in the shape of pills(藥片) and will not be as delicious as they are today. Also, space travel will make many people feel ill.

Liu Xu is a student from a middle school in Guangxi. Once he was riding home when a  robber (盜賊) suddenly jumped out from the roadside. He pulled Liu Xu off his bike and rode away. Liu Xu was scared, but he didn’t run after the robber. He found a telephone and called the police at 110.

Then they changed roles and did it again. They learned a lot while having fun at role-playing.
The topics of the first aid classes are regularly updated (適時(shí)的). The students have learned skills for surviving in earthquakes. The teacher also taught the students not to go out at night. If someone tried to do bad things to them, they should quickly run into crowed place.

What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Architects believe that they are all possibilities. The only thing for sure is that the houses will be as green as possible.
The tree house
Many architects in the world would like to build a “tree house.” Like a leaf, the surface of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even create fresh air for the home. The “root” (根) of the house is deep under the ground. It uses the soil (土壤) to the home’s temperature.
The Lizard house
Like a lizard (蜥蜴), changing color with the weather is the most important design of a lizard house. When it’s in the bright sun, the cover of the house will turn dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.
Meals at home
This design is perhaps as much about the future of food production as architecture (建筑風(fēng)格). It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.
Learning from the past
Looking to the future isn’t the only way to be green. Sometimes, ancient techniques (古老的技術(shù)) can also help cut down energy use. For example, a chimney (煙囪) can be a useful air conditioner because it is easier of hot air to flow out at the chimney.
小題1:What is the best title (標(biāo)題) of the passage?
A. Green house of the future.
b. The greener, the better.
C. How to build green houses.
D. Changes of the houses.
小題2:We can heat water, produce electricity or create fresh air for the home            .
A. with the root of a leaf.
b. with the energy from sunlight.
C. with the soil under the ground
D. with gardens on its walls.
小題3:What will happen to the cover of the lizard house when it’s in the bright sun?
A. It will take in light.
b. It will produce energy.
C. It will turn dark.
D. It will turn white.
小題4:The passage seems to tell us that meals at home in the future            .
A. will be more delicious.
b. need more cooks.
C. cost as much as possible.
D. will be greener.
小題5:A chimney can be a useful air conditioner but it used to cause          .
A. pollution.   b. accident.     C. noise.      D. techniques.

One day when some government officials were rebuilding a house, they found a mouse hole in a corner and used smoke to make the mice inside the hole come out. A while later they saw mice running out, one after another，but they saw two mice didn’t run away immediately. It seemed that one was trying to bite(咬) the tail of the other.

Dolphins are our friends. They can use tools to solve problems although they don't have hands.   For example, scientists have ever found that a dolphin can make a shy eel(鰻魚(yú)) come out of its hole with a dead fish.
Dolphins use different sounds to exchange information with each other. Scientists in Hawaii have developed a sign language to give instructions to dolphins, and the results are amazing. They find that dolphins not only understand the meaning of individual (個(gè)別的) words, but also understand the importance of word order in a sentence.
Most animals enjoy playing — but dolphins seem to like making their games as challenging as possible. On a beautiful day in 1997, scientists at a beach watched a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins came up to the dog and then started throwing it into the air. The dog seemed to enjoy the "game" and continued playing with the dolphins for more than an hour.
Dolphins live in a very different world from ours, but they are very good at our "IQ tests” . For example, they will jump out of the water when they hear a whistle (口哨) noise. They do this because they will get a fish as a prize.
There is still much to learn about these cute problem-solvers, but it is certain that watching a dolphin show is fun.
根據(jù)短文內(nèi)容，選擇最佳答案。（5分）
小題1: What can a dolphin use to make an eel come out of its hole?
A．Its mouth. B．Its head. C．A dead fish. D．A little dog.
小題2:How do dolphins exchange information with each other?

C．By using words. D．By using sounds.
小題3:Where did the dolphins throw the dog when playing?
A．Onto its back.B．Into the air.
C．Onto the beach. D．Into the water.
小題4:Why do the dolphins jump out of the water when they hear a whistle noise?
A．Because they want to get a fish as a prize.
B．Because they enjoy playing on the water.
C．Because they want to play with other dolphins.
D．Because the dolphin keepers want them to come out.
小題5: Which of the following is TRUE according to the passage?
A．Dolphins understand many languages.
