If you don’t have a college degree, you’re at greater risk of developing memory problems or even Alzheimer’s (老年痴呆). Education plays a key role in lifelong memory performance and risk for mental disorder, and it's well documented that those with a college degree possess a cognitive（认知的） advantage over those less educated in middle and old age.
Now, a large national study from Brandeis University published in the American Journal of Geriatric Psychiatry shows that those with less schooling can significantly make up for poorer education by frequently engaging in mental exercises such as word games, puzzles, reading, and lectures.
“The lifelong benefits of higher education for memory in later life are quite impressive, but we do not clearly understand how and why these effects last so long,” said lead author Margie Lachman, a psychologist. She suggested that higher education may encourage lifelong interest in cognitive efforts, while those with less education may not engage as frequently in mental exercises that help keep the memory agile (敏捷地).
But education early in adulthood does not appear to be the only route to maintain your memory. The study found that intellectual activities undertaken regularly made a difference. “Among individuals with low education, those who are engaged in reading, writing, attending lectures, doing word games or puzzles once a week or more had memory scores similar to people with more education,” said Lachman.
The study, called Midlife in the United States, assessed 3,343 men and women between the ages of 32 and 84 with an average age of 56 years. Almost 40 percent of the participants had at least a 4-year college degree. The researchers evaluated how the participants performed in two cognitive areas, verbal (言语的)memory and executive function --- brain processes involved in planning, abstract thinking and cognitive flexibility. Participants were given a series of tests, including tests of verbal fluency, word recall, and backward counting.
As expected, those with higher education said they engaged in cognitive activities more often and also did better on the memory tests, but some with lower education also did well, explained Lachman.
“The findings are promising because they suggest there may be ways to level the playing field for those with lower educational achievement, and protect those at greatest risk for memory declines,” said Lachman. “Although we can not rule out the possibility that those who have better memories are the ones who take on more activities, the evidence is consistent with cognitive plasticity (可塑性), and suggests some degree of personal control over cognitive functioning in adulthood by adopting an intellectually active lifestyle.” What is the text mainly about?
| A．Higher education has a better cognitive advantage. |
| B．Better memories result from college degree. |
| C．Cognitive activity does good to one’s mind. |
| D．Poor education has more risk of memory declines. |
According to the result of Margie Lachman’s study, we can conclude that ________.
| A．education is responsible for the lifelong memory performance and risk for mental disorder |
| B．education early in adulthood can be the only route to maintain your memory |
| C．those with higher education did better on the memory tests than those with lower education |
| D．an intellectually active lifestyle does help to maintain your memory |
What do we know about the study called Midlife?
| A．Participants each were given a battery to test their memory. |
| B．The average age of the participants are 56 years old. |
| C．Participants had to perform in one of the two cognitive areas. |
| D．One in four of the participants had a 4-year college degree. |
Why are the findings of the Lac
hman’s study promising?
| A．The lower educated may have the same opportunities to keep up memory. |
| B．We may have ways to cure the people who have memory declines. |
| C．Adopting a different lifestyle can control cognitive functioning. |
| D．We can find out the possibility to have better memories. |
Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda（大熊猫） eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

As computers become more popular in China, Chinese people are increasingly relying on computer keyboards to input Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes（笔画）of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.
Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more wide-spread among university students. Almost all their assignments and essays are typed on a computer.
All the students interviewed say they usually use a computer.
It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.
“When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I’m familiar with it.”
“I'm not in the mood to write when faced with a pen and paper.”
Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?
Many educators think differently. Shi Liwei, the headmaster of a famous primary school in the capital said, “Chinese characters enjoy both practical and aesthetic (审美的) value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them.”
To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory (必修的) and in universities, some professors are asking students to turn in their homework and essays written by hand.Which of the following can best serve as the title of the passage?
| A．The Importance of Handwriting and Typing |

A famous teacher was speaking to the students at our school. He began his lesson by holding up a ￡100 bill. Then he said to the three hundred students, "Who would like to have this ￡100 bill?" The students began to put up their hands at once.
Then he said, "I am going to give this bill to one of you, but first, let me do this." He then made this bill into a ball. Then he said, "Who wants it?" Hands went into the air.
"Well," he said, "What if I do this?" and he dropped it on the floor and stepped on it. He picked up the dirty, crumpled bill and said, "Who still wants it?" Hands went back into the air.
"My friends," he said, "You've learned a valued lesson today. No matter what I did to the money, you still wanted it because it didn't go down in value. It was still worth ￡100.
Many times in our lives, we're dropped, crumpled, and stepped on by the chances we take and the things that happen to us. We feel as if we are worth nothing. But remember, no matter what has happened to you, you will never lose your value. You are always valuable to those who love you. Your value doesn't come from what you drop or whom you know，but WHO YOU ARE .

| A．when the teacher gave the students some advice on how to learn English |
| B．when the students were having a meeting |
| C．when the teacher gave the students a speech |
| D．when the students were discussing something interesting with their teachers |
Even though the money was dirty, it _______.
| A．went up in value | B．was worth much |
| C．didn't reduce in value | D．was still ours |

means_______.
| A．the students put up their hands again |
| B．the students put down their hands |
| C．the students agreed to what the teacher said |
| D．the students put their hands in front of them |
Why did the famous teacher use a ￡100 at his lesson?
| A．Because he wanted to give a lecture about money. |
| B．Because he was used to dropping a bill on the floor and stepping on it. |
| C．Because he was going to give the bill to one of the students. |

| B．All people love money most. |
| C．Your value doesn't change no matter what happens to you. |
| D．The value of money changes when it is made dirty. |
A new argument has been put forward as to whether penguins are disturbed by the presence of tourists in Antarctica.
Previous research by scientists from Keil University in Germany monitored Adelie penguins and noted that the birds’ heart rates increased dramatically at the sight of a human as far as 30 meters away. But new research using an artificial egg, which is equipped to measure heart rates, disputes this. Scientists from the Scott Polar Research Institute at Cambridge say that a slow moving human who does not approach the nest too closely, is not viewed as a threat by penguins.
The earlier findings have been used to partly explain the 20 per cent drop in populations of certain types of penguins near tourist sites. However, tour operators have continued to insist that their activities do not adversely affect wildlife in Antarctica, saying they encourage non-disruptive behavior in tourists, and that the decline in penguin numbers is caused by other factors.
Amanda Nimon of the Scott Polar Research Institute spent three southern hemisphere summers at Cuverville Island in Antarctica studying penguin behavior towards humans. “A nesting penguin will react very differently to a person rapidly and closely approaching the nest,” says Nimon. “First they exhibit large and prolonged heart rate changes and then they often flee the nest leaving it open for predators (掠夺者) to fly in and remove eggs or chicks.” The artificial egg, specially for the project, monitored both the parent who had been ‘disturbed’ when the egg was placed in the nest and the other parent as they both took it in turns to guard the nest.
However, Boris Culik, who monitored the Adelie penguins, believes that Nimon’s findings do not invalidate his own research. He points out that species behave differently ---- and Nimon’s work was with Gentoo penguins. Nimon and her colleagues believe that Culik’s research was methodologically flawed because the monitoring of penguins’ responses needed capturing and restraining the birds and fitting them with beart-rate transmitters. Therefore, argues Nimon, it would not be surprising if they became stressed on seeing a human subsequently. According to the passage, what overall message is presented?
| A．No firm conclusions are drawn. |
| B．Neither Culik’s nor Nimon’s findings are of much value. |
| C．Penguin reduction is closed related to tourist behavior. |
| D．Tourists are not responsible for the fall in penguin numbers. |
Which ONE argument of the following is stated in the passage?
| A．Penguins are harder to research when they have young. |
| B．Tour operators should encourage tourists to avoid Antarctica. |
| C．Not all penguins behave in the same way. |
| D．Penguins need better protection from tourists. |
What do you notice about the views presented in the passage?
| A．They are groundless. | B．They are factual. |
| C．They are descriptive. | D．They are conflicting. |
What does the underlined word (final line) probably mean?
| A．Later on. | B．Calmly. | C．Separately. | D．In the same place. |
