I was selected to work in a school with children with disabilities . I had a lot of rooms to choose from, but I chose to work in the room that was for children with severe disabilities. They had no speech and most were in a wheelchair. The teacher of that room asked if I would work with a girl who had epilepsy and other brain disabilities. She was 15 years old. The teacher thought that it was an achievement for her to be able to put on her coat all by herself. I saw more in her. She always wanted to put string through the shaped blocks to make a necklace. For the 5 years she was in the school the teachers always tried to help her but always ended up doing all the work. I knew this smart girl could do more and so I encouraged her. She had a thumb which she could not move but I encouraged her so much to try. She got very upset most days and sometimes I wanted to give up. Finally after a week this young girl was able to do what she had been wanting to do by herself for so many years. Her teacher cried when she saw what this girl was able to do with just some encouragement. I wish everyone would encourage people rather than tell them they can't or do it for them. Question: We can learn from the passage that _ . - the writer was willing to take on big challenges - the girl was helpful even if she had disabilities - the writer didn't like working with the children at first - the girl's health improved a lot with the writer's help

Read the following article and select the best answer. Article: It's a safe bet that a robot made your car and made your computer. Pretty soon, they could be making your bed and breakfast too. Increasingly, engineers are saying that robots are going to move out of research departments and into your home. Companies including General Electric are working on designs for small robots. Products like the Roomba, a robot that can clean floors, are flying off the shelves. What's behind this new robot revolution? It's partly a matter of technology. Devices that can recognize and respond to a human voice have been developed. There are now a few different ways for robots to move around. They can walk, crawl or ride on wheels. Robots are being made smaller and smaller. They are also becoming more and more able. A bigger part of the story is on the demand side. From the day the television remote control was invented, people around the world have searched for new ways to be lazy. Take into consideration that more and more people can afford robots, and the time seems ripe to introduce robots to the ordinary family. To be sure, robots that walk on two legs and talk like people are still a long way off. However, robots that do basic housework such as cleaning or gardening are sure to come out soon. One thing is certain--when these robots do come into our homes, it will change things forever. Question: Which plays a more important role in revolutionizing the robot? - Science and technology. - Rapid development of companies. - Effective marketing means. - Great demand from the buyers.
Great demand from the buyers.

*Question*
Read the following article and select the best answer. Article: Boys and girls,as we all know,most people,especially young people ,tend to care about their hair much because hair plays a very important role in our appearance.But can you imagine what other uses hair has?Do you have any idea that human hair may become a new solar energy soutce?Before we begin with the new content of our Physics ,let me tell you a new invention first. It's reported that a Nepali teenager has designed a $32 solar panel using human hair. Milan Karki,who is 18 years old and lives in a village in rural Nepal,used human hair to replace silicon ,which is a common but expensive componet of solar panels. By using hair as a replacement,Karki says that solar panels can be produced for around $32,a price that could be halved if they were mass-produced. The solar panel works,because melanin ,which gives hair its colour,is light sensitive and can act as an elecrtical conductor.Kaiki was inspired to think of the idea by a Stephen Hawking book ,which explained how to create elecrtic energy from hair. The device that Karki has invented is capable of producing 9V or 18V of energy--plenty to charge a mobile phone. "Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months;whereas a pack of batteries would cost50p and lasts few nights,"according to The Daily Mail. The solar panel is claimed to be easy to service as the hair is easy to replace. Karki has now seng out several devices to other disrticts near his home for tetimg .He said,"First I wanted to provide elecricity for my home,then my village .Now I am thinking for the whole worle." So next time when you have a haircut,do remember to keep your hair cut down to use for energy.Perhaps you can also provide elecrticity for your home,even your village using your own hair. Question: Which of the following is true about the new invention? - We can buy solar panel for around $32 using hair as a replacement in the market. - The device can produce 9V or 18V of energy. - Karki thought of the idea of inventing the device all by himself. - Kaiki provides elecrticity for his home using hair.
