During the winter vacation,I was involved in an image-processing project. My task was to extract（提取）the shape of every cell from a(n)__ of microscope images. It seemed quite straightforward at first,but it turned out to be __.

Since I did not have any experience in image processing,I studied some basic ___on my own and started to use a very popular function library(函数库）called OpenCV. As the time was __,I just learnt to apply techniques without going into the mathematical rationale(原理）。As a result,I didn't complete the task in an efficient way and____lots of time.

Through this project,I got a good __ of the importance of studying the basic knowledge. I will probably ___to spend more time studying the theory before I ___another project. By learning their underlying mechanisms(机制），I will be able to ___the tools to suit my own needs. In this way,1 may achieve___ results.

Another challenge I met was about the brightness setting. When I sketched(勾勒）the __ of the cell by the computer,I first set the brightness value to 50,___that the computer could delete the dark places and extract the shape of the cell___. But it turned out that the standard didn't fit for every image. So 1____the brightness value to 30,but that didn't __ either. It was very hard to find a value that worked for all ____

From this,I began to appreciate human eyes. Our eyes ___the amount of light entering them automatically through a feedback system to achieve the best image representation,but computers are not that __. There is still so much that we don't know about the human body.

In summary,I think it is good for students to be involved in real projects___ they can begin to learn about various fundamental ___and get themselves ready for the future.

    What is happiness? When you can feel inner peace and satisfaction, you are happy. 1. This usually happens when we do something we love or achieve something that we value. It is our opinions that make us feel happy or unhappy. All of us constantly go through various situations or conditions, but we do not have to let them influence our reactions and feelings.2..

Try hard to make a change of the way you look at things.3. That means looking at the good and positive side of every situation. Pay attention to solutions, not problems. Listen to relaxing and uplifting music. Watch funny and interesting programs that make you laugh.

Always look at what you have done and not at what you haven’t done. Look at what you can do, not at what you cannot do. Each day do at least one act to make others happy. When you make someone happy, you’ll become happy, and then people will try to make you happy.4. On the contrary, be happy for their happiness. Communicate with happy people and try to learn from them to be happy. Remember ? do your best to stay detached (冷静的) when things do not occur as intended and desired. Detachment has much to do with inner peace.5.

A.I’ve never regretted it.

B.Always look at the bright side.

C.Do not envy people who are happy.

D.Stop asking for everyone’s approval.

E.Inner peace can lead to happiness, so smile more often.

F.Here are a few tips for increasing happiness in daily life.

G.It is usually experienced at a special moment.

    We tend to believe that older people are more positive and younger people are more sensitive to social cues (暗示).

Recently scientists investigated this idea by testing 10,000 men and women. They wanted to see if age affected a person’s ability to identify subtle facial emotions, such as fear and anger.

The researchers from McLean Hospital in the US used a Web-based platform to collect happiness data. It showed the participants two headshots (头部特写) of random people. They were then asked to identify which subject was angrier, happier, or more fearful. The research found that younger people were able to better identify angry and fearful facial cues than older people.

“From the previous studies , we know that the everyday experiences of an adolescent are different from an older person, but we wanted to understand how these experiences might be linked with differences in basic emotion understanding,” wrote Laura Germine, the study’s senior author.

But what is it that makes young people more sensitive?

“This is the exact age when young people are most sensitive to forms of negative social cues, such as bullying,” Lauren Rutter, the study’s lead author, told Science Daily. “The normal development of anger sensitivity can contribute to some of the challenges that arise during this phase of development.”

On the contrary, across the whole 10,000-person survey, researchers found no decline in the perception (感知)of happiness among older participants.

“What’s remarkable is that we see declines in many visual perceptual abilities as we get older, but here we did not see such declines in the perception of happiness,” Germine told Neuro Science News.

She added that these findings fit well with other research, showing that older adults tend to have more positive emotions and a positive outlook.

Following the paper’s release, Rutter told Neuro Science News that gathering their primary research online allowed the team to tap into a “much larger and more diverse sample set” than previous studies.

1.What is the result of the research?

A.We are often bullied while young.

B.We become less positive as we get older.

C.The younger we are, the happier we feel.

D.The younger, the more sensitive; the older, the more positive.

2.What makes young people more sensitive according to the text?

A.Their family backgrounds. B.Their negative experiences.

C.People around them. D.Their visual perceptual abilities.

3.How does the author support the theme of the text?

A.By giving examples. B.By stating arguments.

C.By explaining statistical data. D.By providing results.

4.Where is the text most probably taken from?

    Not long ago, few little girls imagined they could grow up to become astronauts. For years in the United States, only men had that opportunity. In 1983, that changed. Sally Ride made history by becoming the first American woman to travel to space.

On Monday, Ride died at the age of 61, “Sally was a national hero and a powerful role model,” President Barack Obama said in a statement. “She inspired generations of young girls to reach for the stars.”

Ride became interested in space when she was a kid. “If you asked me when I was 12 whether I wanted to be an astronaut, I’m sure I wou1d have said yes,” she said in a 2010 interview . “But I didn’t even think about that as a possible career.”

After studying physics in college and graduate school, Ride got her chance. She was accepted into NASA’s astronaut training program in 1978, and then chosen to be the first American female in space. In 1983, she blasted into space aboard the Challenger shuttle. “There is no amusement park ride on the Earth that even comes so close,” she said.

Ride returned to space on the Challenger a second time in 1984. Between the two missions, she spent a total of 343 hours in orbit. After that, she remained involved with the space program and also worked to share her passion for science with kids. She co-authored six science books for children , and started her own science education company.

Ride knew that she held a unique place in history. “I realized how important it was for a woman to break that barrier and open the door for other women to be able to do the same exciting things that the men had been doing,” she said.

Since Ride’s historic trip, more than 40 other American women have traveled to space.

They all had Ride to thank for opening the door to the final frontier.

    I always had the preference to take on more than I should when I was young. At times, I wanted to prove to myself that I could handle it. At other times, my purpose was to please someone and gain recognition for my efforts. Sometimes this led to stress or frustration.

When I was an IT manager after college graduation I was assigned to work with a wealthy customer and be a go-between (中间人)for my company. I took on the assignment happily, thinking that this might be my time to shine. However, the customer’s demands proved to be more than I could do with. And the company chose to stand by the customer and try to meet his unreasonable requirements rather than stick to what we had originally offered in the contract. As you can imagine, this led to a lot of unexpected problems and arguing with some of the staff who refused to do anything outside their scope (范围) of work. I remember walking into my office one morning, opening my laptop and staring at the blank screen for long, thinking to myself: What should I do? That was a difficult time in my life and then I finally had to give up my first job and left that company sadly.

Perhaps, I thought then, I could find the job that didn’t involve dealing with difficult people and difficult situations. But later I realized: Is this possible in our modern world? No, it is impossible. Now, I know, I shouldn’t run away from the challenges I faced in life: I had to learn how to deal with them. I regret not persevering ( 坚 持 ) in my job. We should train ourselves to look at things from a positive point of view, because that is far better than being trapped in the bad circle depression. I’ve come to see that when faced with difficulties, I should not give up, but persevere.

The Make-up Guy

Dave was a make-up (化妆) artist who regularly held makeup artistry classes at the local community college. He was well known as an excellent trainer and enjoyed great popularity.

Usually, the majority of his students were middle-aged housewives, who wanted to fine-tune their make-up skills so as to make themselves more attractive. But this time, it was beyond him that his class was attended by a man as well.

The new student was a gentleman in his best years with a seemingly boundless interest in make-up artistry. He was keen to learn as much as he possibly could and asked questions whenever and wherever possible. He was so absorbed in learning that he wouldn’t stop until he was satisfied with the result of his work.

Understandably, the man was the number one subject of conversation when the other women were alone.

Speculations (猜测) quickly started to spread. Why did he learn make-up? Was he to seek for a woman to be his life partner? How about my neighbor’s youngest daughter? Why on earth would he attend such a woman class? Who could it be?

Doubts like this came crowding in.

The community college was placed in a remote rural area, which was why the other participants were quite doubtful of the man’s intentions.

Throughout the lessons, ignoring the curious women around him, the man carefully listened and wrote everything down he learned, leaving the women more and more curious and puzzled.

When the day and class were slowly coming to an end, the gossiping women simply could not hide their curiosity any longer, for they knew it was time to remove their doubts, otherwise …

Finally, one of them couldn’t resist her curiosity, so she picked up the courage and asked him why he was so interested in make-up artistry.

What followed was a dead silence. After what seemed a century, he slowly opened his mouth and here came the most inspiring beautiful reply.

Paragraph 1:

He said his beloved wife partially lost her eyesight because of diabetes (糖尿病) and she was no longer able to apply her make-up.

Paragraph 2:

So he decided to take the course to surprise his wife.

Making the Most of Life Experiences

If you ask anyone what the purpose of life is, you’ll likely receive wildly different responses. The answer to this question is deeply personal because different things are important to us throughout the course of our lives. 1.

Finding ways to make the most of our experiences is a challenge we face every day. Here are some ways to make your experiences meaningful.

Follow your dreams.

The number one way to live a life free of regret is to follow your dreams. Passion will die without actions supporting them. 2.Every day take an action, no matter how small, to achieve your goals. Each day is a step forward and none of it is wasted.

Make lots of mistakes.

3. Many of my strongest memories come from the times I’ve failed，and those lessons have stayed with me. Failure is beneficial to us. And time allows me to see the value of even the most painful situation.

4.

Difficult and painful experiences shape our character but can also weigh us down. These prevent us from moving forward. So much of our progress in life relies on willpower and a healthy emotional stale. If you’re under stress, your body and mind both require time to recover. 5.

For me, life is about experiences. We all have to dream, work hard, and fail before we can achieve success. Maybe we’ll discover along the way that the journey is more important than the destination .

A.Take care of yourself.

B.Improve your personality.

C.Making mistakes is the surest path to grow as a person.

D.It’s best to rest, recover, and slowly build back up your strength.

E.Yet one thing stays with us no matter where we go: our experiences.

F.Though we try our best to make fewer mistakes, it is impossible to avoid them.

G.Though we can’t choose the outcome of our actions, we can choose to keep pursuing(追求）.
