TOKYO，JAPAN — What do you do when you see a cockroach （蟑螂）？Do you hit it with a newspaper？Do you step on it？
When researchers at Tokyo University see a cockroach，they take the remote control and make the cockroach turn around，run left or right，or go forward.These scientists are changing the cockroaches into robots.Each cockroach has a very small packet that has in it a microprocessor（微處理器）.Then researchers can send signals from the remote control to the packet.The signals control the movements of the cockroaches.
Why does anyone want to control a cockroach？ "Insects can do many things that people can't，" says Isao Shimoyama，head of robot research at Tokyo University.In a few years，he says，these robot insects will carry very small cameras.They will be able to move through earthquake rubble（瓦礫） to look for people or move under doors to find information about someone.
This may seem strange，but the Japanese government thinks the research is very important.The government is giving the scientists ＄ 5 million for this research.
First，the researchers breed （培育） hundreds of cockroaches.They use only the American cockroach because it is bigger and stronger than other cockroaches.Then they choose the best cockroaches and remove their wings and antennae（觸須）.They put small packs where the antennae were.The packs weigh about three grams，or about two times the weight of the cockroaches themselves. "Cockroaches are very strong，" says Ralph Holzer，who is a researcher at Tokyo University. "They can lift 20 times their own weight."
With a remote control，the scientists send signals to the packs.When a cockroach gets the signal，it moves.The problem is that the cockroaches don't always move in the right direction.

1．According to a new curriculum standard（課程標準）for labor education in compulsory（強制的；義務的）education made by the government，students in primary and middle schools have at least one course every week on basic household skills such as cooking.
Cooking should be considered as art just like any other activity which requires skills and knowledge.It is often said that students are supposed to learn scientific facts as well as how to prepare meals.The following will explain why cooking should be taught in schools.
Some students talk about their experience about the cooking classes.1.Cooking is an important skill in life.Schools are supposed to teach knowledge to the students so that they can lead successful independent lives when they are out of school.Also，they can step into the world knowing how to make a living.
2.Cooking helps discover future career.When schools offer cooking lessons，students will show an interest in it and might take cooking as a career.This will give them the chance to perfect their basic skills and be creative in the kitchen.
3.Cooking avoids wasting money.Students used to spend a lot of money on ready-made food，while in the real sense they can prepare a nice meal with less cost by buying the required ingredients.
Cooking skills are much more useful than a lot of what is taught in schools，but it does require some fully equipped（配備齊全的）kitchens.I hope these classes will be good for students and not be seen as window dressing.Michael：By learning cooking skills like，I can learn how to take care of myself and live independently.For example，I can cook eggs while my parents are busy with their work.Some-times I can prepare meals for them.
Linda：I made fried chicken by myself yesterday.First I mixed together some onions，salt and pepper.Next，I filled the chicken with the mix.Then，I put the chicken in a hot oven and cooked for a few minutes.Finally，I put the chicken on a plate and cut it into thin pieces.How delicious it was!
（1）What kind of activity is cooking？
（2）Why does cooking helps discover future career？
（3）What does cooking avoid？

2．We all know the sun is important.It makes life on our planet possible.But how does the sun do that？It's the sun's energy.
Energy from the sun is called solar energy（太陽能） It comes in the form of light or heat.People have used solar energy for thousands of years.The sun's energy can be used to heat water and even food.If you own a magnifying glass，your parents have probably warned you not to leave it in the sun.Solar energy can actually make the magnifying glass burn objects underneath it causing a fire.This type of energy from the sun is called solar thermal（熱的）energy.
We can also turn the sun's light into electricity.This is done with solar panels（板）.Solar panels are made up of a material called silicon（硅）.The silicon is heated and formed into very thin wafers（晶片）.When the sunlight hits the solar panel，the electrons in the silicon move and flow through wires（電線）.Using this technology，we can run a calculator and even power cars in an easy way.
But what happens on cloudy days？The electrons in the silicon will stop moving，which means the electricity can't flow.But this doesn't mean that solar energy can only be used on sunny days.People can use the batteries（電池）which are attached to（附著于）solar panels to store the electricity.So the stored electricity can be used to power cars at night or on cloudy days.
Did you know that solar energy is not as expensive as it used to be？In fact，in the last few years.jye.ai panels have become much more affordable for people to use.Since the sun gives off more energy in one second than people have used，imagine what we could do if we used the sun's energy to power our planet.We all know the sun is important.Its energy makes life on our planet（1） .Energy from the sun is called solar energy.It comes in the form of light or heat.People have（2）solar energy for thousands of years.The sun's energy can be used to heat water and even food.This type of energy from the sun is called solar thermal energy.We can also turn the sun's light into（3）with solar panels.Using this technology，we can run a calculator and even power cars（4）.People can use the batteries which are attached to solar panels to store the electricity.So the stored electricity can be used to power cars at night or on（5）days.發(fā)布：2024/12/27 18:30:2組卷：2引用：3難度：0.5 -
