Gianni has a very special kind of memory. He explains in his own words: “It’s a kind of memory that is connected to what I see. It means that every idea I learn, everything I read, becomes a part of me. Normally, a person who doesn’t have this gift, and who hasn’t studied memory, tends to just forget things—even an entire book. Not me.” Gianni says that his “gift”, or special ability, he has memorized more than 250 books!
Memorizing over 250 books is surprising, but it’s not the only surprising thing about Gianni. He says that he can remember every detail of every day of his life. He also says that he can remember these details from the time he was less than one day old!
Researchers are now studying how memory and learning change the brain. Some research already shows that a great memory may not depend on the right DNA only. It seems that everyone can remember more if they try. According to Dr. Malgaroli, “If you really need to use your brain to store some kind of information, you have this ability. It’s just a matter of exercise.” So, practice and exercising the brain can improve the memory!
The same idea is true for Gianni. His gift is just only part of his success. Since the age of 11, he’s been training his brain to remember more and more. He practices continuously to improve the power of his memory. Gianni thinks about memory, and works on it, all the time. He has even memorized a whole series of historical books!
Gianni believes his memory is mainly because of his very hard work. He even holds classes to teach others how to improve their memories. In his classes, Gianni shows people how to organize their memories and how to “remember to remember”. “I think the only problem with memory is the correct order. There’s a lot of brain space, so I think there are no limits.”
1. Which of the following best describe Gianni
A. He enjoys reading. B. He is a clever student.
C. He can remember well. D. He connects what he sees.
2. What can be learned from some research on memory
A. Good memory comes from your gene.
B. Not everyone can have a good memory.
C. Practice can help build up your memory.
D. Brain is mainly used to store information.
3. Why did Gianni memorize books
A. To study brain science. B. To develop his memory.
C. To improve his knowledge. D. To prepare for historical tests.
4. Which is the best title of the passage
A. The Memory Man B. An Unforgettable Memory
C. Mental Athletes D. Special Power to remember
B 阅读填空
It is often said that the best way get to the bottom of a hard problem is to sleep on it. Does this make sense ____1____
A team of researchers at Northwestern University, US, found that sleeping is useful in both strengthening (增强) and reorganizing (重组) memory This can help you solve problems.
The researchers did an experiment on 57 university students. They asked students to solve 42 difficult puzzles on the first day. Students worked on each puzzle while listening to different music. ____2____ By the end, there were six puzzles that the students still hadn’t solved.____3____ They were given special sleep-monitoring (睡眠监测) and music devices (设备). The devices played music connected with the unsolved puzzles while the students were in the slow-wave (慢波) sleep stage (阶段). This stage is when people are likely to dream and recognize their memories.
The next morning, the students tried the unsolved puzzles again. Researchers found they were 55 percent more likely to solve them. The music activated (激活) the memories they had of the puzzles while they were sleeping. ____4____
Former studies of both people and animals have shown that sleep can not only strengthen memory, but also help us organize and send information. ____5____ So the next time you face a difficult problem, sleep on it. Play some music to remind yourself of the problem.
A. A new study shows that it does.
B. This study is more evidence (证据) of these findings.
C. The research encouraged students to remember the music they heard while solving the puzzles.
D. The students then went back home to sleep.
E. It allowed them to work" on the puzzles in their sleep.
F. They didn’t want to give up.

五、阅读理解
Gianni has a very special kind of memory. He explains in his own words: “It’s a kind of memory that is connected to what I see. It means that every idea I learn, everything I read, becomes a part of me. Normally, a person who doesn’t have this gift, and who hasn’t studied memory, tends to just forget things—even an entire book. Not me.” Gianni says that his “gift”, or special ability, he has memorized more than 250 books!
Memorizing over 250 books is surprising, but it’s not the only surprising thing about Gianni. He says that he can remember every detail of every day of his life. He also says that he can remember these details from the time he was less than one day old!
Researchers are now studying how memory and learning change the brain. Some research already shows that a great memory may not depend on the right DNA only. It seems that everyone can remember more if they try. According to Dr. Malgaroli, “If you really need to use your brain to store some kind of information, you have this ability. It’s just a matter of exercise.” So, practice and exercising the brain can improve the memory!
The same idea is true for Gianni. His gift is just only part of his success. Since the age of 11, he’s been training his brain to remember more and more. He practices continuously to improve the power of his memory. Gianni thinks about memory, and works on it, all the time. He has even memorized a whole series of historical books!
Gianni believes his memory is mainly because of his very hard work. He even holds classes to teach others how to improve their memories. In his classes, Gianni shows people how to organize their memories and how to “remember to remember”. “I think the only problem with memory is the correct order. There’s a lot of brain space, so I think there are no limits.”
1. Which of the following best describe Gianni
A. He enjoys reading. B. He is a clever student.
C. He can remember well. D. He connects what he sees.
2. What can be learned from some research on memory
A. Good memory comes from your gene.
B. Not everyone can have a good memory.
C. Practice can help build up your memory.
D. Brain is mainly used to store information.
3. Why did Gianni memorize books
A. To study brain science. B. To develop his memory.
C. To improve his knowledge. D. To prepare for historical tests.
4. Which is the best title of the passage
A. The Memory Man B. An Unforgettable Memory
C. Mental Athletes D. Special Power to remember
【答案】1. C 2. C 3. B 4. A

2. 细节理解题。根据“So, practice and exercising the brain can improve the memory!”可知，练习和锻炼大脑可以提高记忆力。故选C。
3. 推理判断题。根据“The same idea is true for Gianni.”和“Since the age of 11, he’s been training his brain to remember more and more. He practices continuously to improve the power of his memory.”可知，记住这么多本书，是为了提高他的记忆力。故选B。
4. 最佳标题题。根据全文可知，主要讲述了Gianni是一个记忆力很好的人，通过他的事例告诉我们：练习和锻炼大脑可以提高记忆力，因此“The Memory Man”符合题意。故选A。
