Blind people use assistive technology (AT) to help themselves. There are many types, and different technologies help to deal with different disabilities. How would you use a computer if you could not see the screen (屏幕)? Don’t worry. Screen readers can help you. With them, blind people can use a system of keyboard orders instead of a mouse to get where they need to go. Screen readers can read aloud the words on the screen to the blind, or they can be connected to refreshable Braille displays (盲文显示机). Refreshable Braille is an electronic way of reading Braille. Refreshable Braille displays can turn the words on the screen into Braille. They can then appear on the screen and can be read with a finger. When the person finishes reading some words, the following words will appear. Refreshable Braille displays are very helpful to people who are deaf and blind. Blind students use AT in the classroom to catch up with their classmates and do homework. Students who have poor eyesight can use an electronic magnifier (放大镜) to see what the teacher is writing on the blackboard. Blind students use refreshable Braille displays to quietly read an e-book. Textbooks can be read with AT, such as hardcopy Braille, refreshable Braille, or the audio format, according to the students’ abilities and hobbies. The development in AT makes it more possible for disabled people to learn, compete, and communicate with normal people. ( )1. What does the first paragraph show us? A. AT is becoming better and better. B. The new technology can bring health to blind people. C. AT makes it possible for disabled people to live a normal life. D.

They can turn the words on the screen into sounds. D. They can help users read in a slower way. ( )3. What is the main idea of Paragraph 4? A. Blind students’ learning ability. B. The challenges of AT in schools. C. Blind students’ physical problems. D. The use of AT in the classroom. ( )4. What can we infer from the passage? A. With the screen readers, the blind people can get anywhere with a mouse. B. Screen readers can’t work alone to help blind people with their reading. C. Refreshable Braille displays can help blind students to read an e-book aloud. D. Textbooks with AT will change for different students’ use. ( )5. Who may be interested in reading this passage? A. Doctors. B. Disabled people. C. Workers. D. Computer users. B Most great inventors often meet with many difficulties in their work before they become successful. George Stephenson, a famous British inventor, made the first train in 1825, using a steam engine (蒸汽机).When he was making the train，he met with a lot of difficulties. Many people said that it would kill animals and the engine would catch fire to their houses. George Stephenson told the people that the train could go on small rails, and it could pull carriages full of things and passengers and there was no great danger to them. It was difficult for him to make them believe (相信). However， after some time, he was able to do it, and the first train that was driven by Stephenson himself showed what he had said. On the train there was a new steam engine. It was invented by him, and it was a complete success. The first day when the train ran on the rails, people along the way heard the noise and saw it running quickly to them. They ran quickly back home and closed their doors. They didn’t come out until it went away. A week later an old woman still said that her hen was so frightened (受惊吓的）that it didn’t lay any eggs for three days. ( )6.
