We all know the saying, “Nobody is perfect.” It has been planted in our brains since we were children, and of course, it is the truth. So if nobody is perfect, why do we have such a hard time admitting when we are in trouble or need help?
Like many other young people trying to get through their first year of college, I felt anxious, and it had its grips on me pretty tight. It began getting in the way（妨碍） of my life, and I had to sit down and tell myself that my behavior was not healthy and there was a solution. Finally, I decided to turn to therapy(精神疗法).
Therapy. It has such a negative stigma (污名), but why? Does going to therapy mean that you are failing as a person or that you cannot fix your problems on your own? No. Going to therapy means that you are strong enough to recognize that something inside your head is not working correctly, and you are brave enough to try to solve it.
After a couple of weeks, many parts of my life became so much clearer. I began to understand that I, myself, am my worst enemy, which was pretty frightening. But, although frightened, I knew that it was only I who could guide me towards feeling better, and that was extremely empowering.
I have been guided towards a healthier mindset, one that is positive and powerful. I have been able to understand that no matter what happens in my life. I will always be okay.
A lot of people do not understand that it is normal to have negative feelings and sometimes to feel like we have lost control over certain parts of our lives. Seeing a therapist can greatly change your way of thinking about something if you keep your mind open and I am so thankful that I decided to go and do something for myself.
So, if you are in need of help, you can go to therapy and then everything will be okay.
1.What does the underlined part in Paragraph 2 mean?
A. Anxiety greatly influenced the author.
B. Anxiety encouraged the author to change.

2.In the author’s opinion, going to therapy ________.
A. means you are failing as a person
B. can be quite unnecessary
C. can make others think wrongly about you
D. means you’re brave enough to solve your problems
3.After a couple of weeks, how did the author react?
A. She became more positive and confident. B. She became too frightened of her own life.
C. She became worried about her anxiety. D. She realized college was her worst enemy.
4.What’s the author’s purpose in writing the text?
A. To tell us how to think positively. B. To show it is OK to be imperfect.
C. To help us know better about therapy. D. To share her college life with us.

We take showers and use the toilet every day to get rid of bodily waste. Our brains also need to take a bath every day. How can they do it?
A 2013 study found the answer. Researchers at the US University of Rochester studied the brains of mice and discovered that they cleaned themselves while the mice slept. A kind of fluid (液体) in the brain, called cerebral spinal fluid (CSF, 脑脊液), was found to increase dramatically (显著地) during sleep, washing away waste proteins that had been building up between brain cells in waking hours.
“This study shows that the brain has different functional states when asleep and when awake,” Maiken Nedergaard, the lead researcher, told NBC News. It also explains why we can’t seem to think clearly after a sleepless night while a good night’s sleep leaves us feeling sharp and refreshed.
Now a new study, published on Oct. 31 in Science, digs a little deeper into our brains’ self-cleaning procedure. Instead of mice, this time humans were the test subjects.
Researchers at Boston University, US, monitored the brainwaves of 13 healthy adults who were sleeping, using accelerated FMRI (核磁共振成像), which is capable of recording faster changes inside the brain than a regular FMRI machine. They found that every 20 seconds, blood flowed out of the brain, making room for a large amount of CSF to come in and “clean”. This cycle coincided with (与....一致) the rhythm of the brain’s slow waves—an electrical activity that happens when we’re in a deep sleep.
It’s still unknown how these brain activities are connected. But the mere fact that they are connected is exciting enough, since it allows researchers to piece together (拼凑出) possible new explanations for misunderstood diseases.
For example, slow-wave sleep has been proven to play a role in strengthening our memories. This may explain why people with Alzheimer (阿尔茨海默病) often have fewer and weaker slow brainwaves. Based on this new study, there could be one more explanation for diseased brains: They are not clean.
Nedergaard, leader of the 2013 study, is also excited about the new findings. “Maybe the most important take-home message is that sleep is a serious thing,” she told Scientific American. “You really need to sleep to keep a healthy brain because it links electrical activities to a practical ‘housekeeping’ function.”
1.What did the researchers find when they studied the brains of mice?
A.CSF in their brains decreased when the mice slept.
B.More waste proteins were produced in their brains during sleep.
C.CSF carried away waste proteins in their brains during sleep.
D.The more CSF was in their brains, the fewer proteins were there.
2.What did the researchers discover when they monitored human brainwaves?
A.It took 20 seconds for CSF to clean brains.
B.Brains were “cleaned” when blood flowed out.
C.The rhythm of the brain was slower than that of CSF.
D.The brains worked more slowly when asleep.
3.What are the last three paragraphs mainly about?
A.The significance of the research.
B.The features of slow-wave sleep.
C.The importance of having a good sleep.
D.The connections between these brain activities.

We can express our feelings and needs by using body language. Cats can do that too. The ways that cats use their tails to show their feelings and needs are interesting.
Unlike dogs, which generally wave their tails to express good feelings, cats use their tails to send a lot of signals. When a cat waves its tail strongly from side to side, it may be a sign for us to leave it alone, or we may get scrathed (抓伤). Throwing a little toy for the cat to play with can get it relaxed. When a cat holds its tail upwards with a slight move, it means the animal is very happy to see its owner.
We all like to cuddle (依偎) inside our bed, and cats do that thing, too. Much as little children like to wrap (用……缠绕) their arms around their Teddy Bears, cats like to wrap their own tails around their bodies to get a sense of safety while asleep. If we notice a cat sleeping in such a position, we should not break its peace.
Usually the tip of the cat’s tail doesn’t draw our attention. But its particular position may also show the cat’s feelings. For example, a cat holding the tip of its tail pointed downwards may try to say that it is not feeling comfortable. So at this point, the cat not only feels angry, but also unsafe. This may again be a sign for us not to upset the cat in any way.
In conclusion, cats use their tails in many different, sometimes funny ways to send us messages, and we can learn to know more.
1.According to the text, in which way are cats different from dogs?
A．Cats draw more attention from humans than dogs.
B．Cats are friendlier to humans than dogs.
C．Cats have more feelings than dogs.
D．Cats show more feelings with tails than dogs.
2.When a cat waves its tail strongly from side to side, it probably feels________.
A．safe B．sleepy C．anxious D．hungry
3.A cat wraps its tail around its body when sleeping to ________.
A．get its tail well relaxed B．get a sense of safety
C．show friendship to its owner D．warn strangers to keep off
4.What does the fourth paragraph mainly tell us?
A．A cat can use its tail tip to show its feelings.
B．We should pay attention to the tip of a cat’s tail.
C．Why a cat holds the tip of its tail pointed downwards
D．A cat has many ways to express its feelings

One of the areas of our body which conveys most about how we feel is how we move our hands and arms. 1. ,but most often they occur unconsciously and naturally.

Openness or honesty. 3., they will often hold one or both of their hands out to the other person. Footballers who have just committed a foul(犯规) often use this gesture to try to convince the referee that they didn't do it.
