一、阅读理解
Running is one of the most popular forms of exercise. Now, a new study shows that running could help you live longer. Researchers at Brigham Young University have found that running for just 75 minutes a week could add 12 years to a person’s life.
The study looked at how running influenced biological age—meaning how old a person’s cells(细胞) are. It is not the same as how long a person has lived. Looking at biological age is a great way to understand how healthy a person is and how long he is likely to live.
To see how people’s cells were aging, the research team looked at telomeres(端粒), which are structures at the end of chromosomes(染色体). Longer telomeres mean healthier cells, while shorter telomeres are connected to an increased risk of death and serious health problems.
As people get older, telomeres naturally get shorter, but a healthy lifestyle can slow down this process.
The research team studied over 4,400 adults and divided them into three groups: a group that ran less than 75 minutes a week, a group that ran at least 75 minutes a week, and a group that didn’t run.
The researchers found that people who ran at least 75 minutes each week had much longer telomeres than people who didn’t run. It meant “a biological age difference of almost 12 years in favor of the runners”. For those who ran less than 75 minutes a week, the researchers found no clear difference in telomere length. This could mean that running less than 75 minutes a week isn’t enough to slow biological aging. However, the researchers said further research may show other reasons for this result.
However, they said that their findings certainly support the health benefits(益处) of regularly running for at least 75 minutes a week.
( )1.What can “biological age” tell us
A.A person’s exact age.
B.A person’s cell counts.
C.A person’s health level.
D.A person’s running ability.
C
( )2.How did researchers know if people’s cells were healthy
A.They took scientific tests.
B.They looked at the telomeres.
C.They surveyed people’s daily lifestyles.
D.They counted the number of chromosomes.
B
( )3.What can we infer(推断) from the last three paragraphs
A.Running only has a great influence on adults.
B.People who run at least 75 minutes a week won’t get sick.
C.Researchers will do more research on running in the future.
D.The longer time you run, the longer telomeres you will have.
C
二、完形填空
Once upon a time, a pencil and an eraser were having a conversation about their jobs. Both of them were 1 each other for their hard work. Both of them knew that they were 2 without each other.
Soon, the pencil started to draw a straight line and the eraser was looking at it. 3 , the pencil lost its balance and the line was ruined. Then the pencil got very 4 . It knew the eraser would have to suffer because of its mistake, so it 5 to the eraser. The eraser felt 6 and asked, “For what, my dear friend ”
“I’m sorry that you get hurt because of me. Whenever I make a 7 , you’re always there to erase it. But you lose a part of yourself and get 8 each time,” cried the pencil.

Our 13 are just like the eraser, and we’re like the pencil. They’re always there for us, 14 our mistakes. Sometimes they get hurt when they raise us and with time they become older. But they’re always happy with what they do and will always prevent 15 from being worried or sad.

假设你是Linda,最近收到英国朋友Tom的电子邮件。以下是邮件的内容,请你阅读后回复。
Dear Linda,
How’s everything going Today my friends discussed something about the future life. They said robots would help us a lot in the future. What do you think the life with robots will be like in the future How can they help us I’m looking forward to your reply.
Yours,
Tom
Dear Tom,
I think robots will help us a lot. First, they will help us study. They will help us do homework. If we can’t go to school for certain reasons, we can ask robots to teach us as a private teacher. Second, they will do lots of housework for us. Besides cooking meals,cleaning the floor and washing clothes, robots will also do lots of other housework. Third, robots will make us happy. Playing some kinds of games with us will be one of robots’

tasks. Of course, jobs like playing music and telling stories will be too easy for them. What’s more, robots will know our feelings. For example, when we are sad, maybe they will play beautiful songs to cheer us up.
In a word, robots will play an important part in our lives. Yours,
Linda
