It is common for older people to forget things. Now an American study has found that memory starts to fail when we are young adults. People younger than thirty years of age usually do not know that they are starting to forget information. But scientists from the University of Michigan say the loss of memory has usually already started.
Researchers say people do not observe this slow reduction in mental ability until the loss affects their everyday activities.
Denise Park led the new study. She directs the Centre for Aging and Cognition at the Institute for Social Research at the University of Michigan. Her team studied more than 350 men and women between the ages of twenty and ninety years. The study identified people in their middle twenties with memory problems.
She says young adults do not know they are forgetting things because their brains have more information than they need.
But she says that people in their twenties and thirties are losing memory at the same rate as people in their sixties and seventies.
Ms. Park says people between the ages of sixty and seventy may note the decrease in their mental abilities. They begin to observe that they are having more trouble remembering and learning new information.
The study found that older adults are more likely to remember false information as being true. For example, they remembered false medical claims as being true. Younger people remembered hearing the information. But they were more likely to remember that it was false.
Ms. Park is now using modern imaging equipment to study what happens in the brains of people of different ages. She is studying what parts of the brain older adults use for different activities compared to younger adults. Ms. Park says mental performance is a direct result of brain activity and brain structure. She says keeping the brain active is important. She hopes future studies will identify ways to improve the operation of our aging minds.

Mom’s birthday present? It may be a difficult thing for some people, but for me, it is an easy thing. Mom loved flowers, so every year I sent her flowers. Actually she had a bed of irises (鸢尾花) in the backyard of her small, Indiana farm. They were beautiful. “Take some,” she said, “Dig some up and plant them on the side of your own house.”
But in my yard they became lacking in energy. A year passed, then two, but not one flower appeared. I cut back all their green leaves. I was tired of seeing them so lonely. Finally, I dug the irises up and threw them away.
About that time Mom died unexpectedly. My sister and I sold the farm. I never went back to see the irises. I just couldn’t bear seeing another family living in our home—Mom’s home. Autumn came, then winter. The following spring, as Mom’s birthday approached, I struggled with the question of how to remember her. I stared out the window and saw a few stubborn irises in my side yard sprouting (发芽), —tall, thin but flowerless. Because of seeing them, I decided to order flowers as I always did on Mom’s birthday, and send them to my sister. I wished so badly I could still send flowers to Mom. But that was impossible.
In the morning of Mom’s birthday, I was in my car ready to work. Something in the yard caught my eye. The irises! One had bloomed with flowers, big, showy and purple, as lovely as they ever had been on Mom’s farm. I smiled and turned my eyes upward. I could no longer send flowers to Mom.

We all know that some things are obviously right. For example, it is right to be 1 to other people. It is also right to look after the environment. Some things are2 wrong, too. For instance, we should not hurt or bully(欺负) others, nor should we litter. Rules often tell us what is right or wrong.
Rules can help the public make the right 3,and remain safe. Car drivers have to obey traffic regulations that tell them the right things to do on the road to avoid crashes. Cyclists who give signals before turning or stopping help prevent4.
If people follow rules without taking other matters into consideration, it will be 5for them to form what is sometimes called a “black and white” view. For example, they may believe that people should always tell the truth, and that lying is6 acceptable. Such people always stick to their views, even if it means that they may get into7.
Sometimes it may not be so easy to know8what is right or wrong. Some people choose not to eat meat because they believe that it is 9 to eat animals, but others argue that they can eat meat and 10 be kind to animals; some insist that stealing is always wrong, but others think that one does not need to feel to11 when stealing some food to eat, if lives in a really poor area and he is12. Rules help us live together in harmony, because they show us the right way to13 other. However, some people argue that rules may be 14, having observed that rules change all the time , and that some schools have some regulations and other have different ones ----so who is to 15what is right ?

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
It is very common for you to find yourself in an unfamiliar situation. 1. Yes, everyone tells you to stand on your own two feet and take responsibility for your action, but if you haven’t experienced a situation before, how can you know what to do?
We usually try our best to do everything on our own and not to rely on others, but at certain times calling for help is the best way forward. You can picture the scene of the man—it is usually a man—driving blindly around an unfamiliar town looking for an address he doesn’t know. 2. And he could get to his appointment on time. It is obvious to everybody in such a case that asking for help is not a sign of weakness, but rather the sensible thing to do.
3. For example, you are looking for a new job and need to write your resume(简历). If your pride prevents you from getting help and you just do the writing yourself, it may well cost the opportunity you are seeking. Similarly, when you just started a new job, you often don’t want to admit that you haven’t got the knowledge to finish a particular task, so you keep going and eventually make things worse than they were. This may lead to a diminishing(贬低) of you in the eyes of the boss. 4.
Now you can see that asking for help is not a sign of weakness but is the sensible and mature thing to do. 5. Making your life easier by asking for and using knowledgeable help is not a sign of weakness, but is actually quite a clever thing to do.
A. What’s worse, you are most likely to lose the new job.
B. Actually speaking, asking for help is not a sign of weakness.
C. There are times when you know you don’t have the relevant experience.
D. If only he would stop and ask for directions, he could save lots of time.
E. However, many people tend to make mistakes over and over when help is available.
F. You will also recognize expert help would save your time, energy and money.
G. You can accustom yourself to asking for help sooner or later.
