Mark began to introduce the guest speaker to the listeners, but then stopped for a while. He had forgotten her name.
Barbara hid her valuable things when she went on vacation. When she came back, she couldn’t remember where she’d put them.
Perhaps you’ve had such experiences like these. Most people have. But most of them haven’t realized that they have a memory problem. Neither do they know a simple but important fact: Memory can be improved. If you just accept that, the following will show you how.
First, relax. If you are over worried about something, you’ll forget it. If you keep telling yourself that your memory is bad, your mind will come to believe it and you won’t remember things. When you forget something, don’t follow up with saying like “Oh, my god! I always forget things! ” Such words will have a bad result on you and your memory.
But relaxing isn’t enough. To improve your memory, you’ll need to take an active role. Like your body, your memory can be made strong through exercise. Look for opportunities to exercise your memory. For example, if you’re learning a language, try to actively remember a lot of new words.
If you don’t take notice of things actively, you won’t remember them. So, you can make pictures of what you see in your mind every day. For example, don’t just put your keys down! If you want to find them again, make a mind picture of the place where you’re putting them.
小題1:The first two paragraphs just tell us ________.
A.examples of memory problems
B.Barbara was a very rich person
C.language problems of two persons

C.realizing your memory problems
D.making mind pictures of what you see

Rivers are one of our most important natural resources (資源). Many of the world's great cities are located(坐落) on rivers, and almost every country has at least one river running through it that plays an important role in the lives of its people.
Since the beginning of the history, people have used rivers for transportation(運輸). The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Gangs is great, but it is also important for transportation; Ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeast Asia. The greatest of all for navigation (航海), however, is the Amazon in Brazil. It is so wide and so deep that large ships can go about two thousand miles upon it.
Besides transportation, rivers give food, water to drink, water for crops(莊稼), and chances for fun and entertainment for the people who live along their banks. In order to increase(增加) the supply of crops, engineers sometimes build a dam (大壩) across a river and let a lake from behind the dam. Then people can use the water not only to irrigate (灌溉) their fields but also to make electricity for their homes and industries.
However, large cities and industries that are located upon rivers often make problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals(化學物質) and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits (利益) of this natural resource.
小題1:The greatest river for navigation is ___________.
A.the Amazon B.the Nile
C.the MekongD.the Mississippi
小題2:From a dam, people can use the water for ___________.
A.keeping the rivers cleanB.only making electricity
C.washing clothesD.irrigation and making electricity
小題3:The water in the river is polluted because of _____________.
A.people's drinking water too much
B.people's swimming in the river too much
C.chemicals and other materials
D.people's building a dam across a river
小題4:The best title of the passage is ___________.
A.Rivers in Cities B.The importance of Rivers
C.TransportationD.Natural Resources

Since the 1970s, scientists have been searching for ways to connect the brain with computers. Braincomputer interface(BCI) technology could help people with disabilities send commands to machines.
Recently, two scientists, Jose Millan and Michele Tavella from the Federal Polytehnic School in Lausanne, Switzerland, show a small robotic wheelchair directed by a person’s thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of body cells(細胞). These send signals through the spinal cord(脊髓) to the body part to give us the ability to move. But spinal cord injuries(脊柱受傷) or other conditions can prevent these weak electrical signals from reaching the body part.” Tavella says. “Our system allows disabled people to communicate with outer world and also to control machines.”
The scientists designed a special cap for the user. This head cover picks up the signals from the scalp(頭皮) and sends them to a computer. The computer finds meanings of the signals and commands the wheelchair with an engine. The wheelchair also has two cameras that tell objects in its path. They help the computer react to commands from the brain.
Prof. Millan , the team leader, says scientists keep improving the computer software that finds meanings of brain signals and turns them into simple commands.” The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling objects. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can get advantages from. And the other is sure that they can use the technology for long.
小題1:BCI is a technology that can________.
A.help to make computer systems more modern
B.connect the human brain with computers
C.help the disabled to be healthier
D.control a person’s thoughts
小題2:Which of the following shows the path of the signals described in Paragraph 5?
A.scalp→computer→cap→wheelchair
B.computer→cap→scalp→wheelchair
C.scalp→cap→computer→wheelchair
D.cap→computer→scalp→wheelchair
小題3:The team will test with real patients to_________.
A.make money from them
B.prove the technology useful to them
C.make them live longer
D.learn about their physical condition
小題4:Which of the following would be the best title for the text?
A.Switzerland, the BCI research Center
B.New Findings About How the Human Brain Works
C.BCI Could Mean More Freedom for the Disabled
D.Robotic Vehicles Could Help to Cure Brain Sickness

What's going to happen in the future? Will robots control our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen in 10 to 30 years from now, according to the BBC.
Digital money

We used to pay with cash(現金) for everything we bought. Now when we use a credit card(信用卡) to shop online, money is spent without us seeing it. That means we are already using digital money. Using a card is much easier than searching our pockets for change. It is also safer than carrying a lot of cash.
When ATM cards were first introduced, they were not accepted everywhere. But now it's hard to live without them. It's reported that people in Sweden completely stopped using cash last year, and the US might be next.
Bionic(仿生的) eye
It's no longer something only in a science fiction movie. People who are blind may have a chance to get their sight back—by wearing bionic eyes.
A blind eye can no longer sense light, but a bionic eye can use a camera to “see” the environment and send data(數據) to the mind. Now the bionic eye only allows patients to see lights and unclear shapes. A high resolution(高清的) image could be just a few years away.
Self-driving cars
Unlike a human driver, a self-driving car won't get distracted(分鐘) by phone call, the radio or something outside the window. Sensors(探測器) and cameras on the car would allow it to stick reduce the number of road accidents. You could even take a nap while the car driver itself. In the future, driverless cars would be widely accepted.
小題1:________ has stopped using cash completely.
A.Sweden B.ATM  C.BBC  D.America
小題2:What does the writer mainly tell us about digital money?
A.We use digital money to shop online without paying money.
B.Digital money is most likely to be used instead of cash.
C.Using cash is easier and safer than a credit card.
D.ATM cards are always popular.
小題3:Which of the following statements is TRUE?
A.Bionic eyes only appear in the science fiction film.
B.Human drivers won't get distracted by something outside.
C.The blind wearing bionic eyes may see clearly in the future.
D.There will be no road accidents at all if self-driving cars are used.
小題4:From the report, we can learn some information about ________.
A.culture and art
B.industry and farming
C.science and technology
D.traffic and journey
小題5:Which of the following can be predicted(預測) from the passage?
A.There would be a number of self-driving
B.The blind could use cameras to see things around.
C.We would live a hard life with digital money.
D.Robots would control the world.
