I was thrilled to go on an adventure with my master Rev. Young, a tall man with kind eyes. Mr. Muir was going too. But he said, "Such a helpless creature will only be in the way." I was disappointed when I heard what he said, and yet I still wanted to follow him.

    One stormy morning, Mr. Muir set out alone to study nature. He ordered me to stay behind. But I could not let him go alone, so I followed him into the wild weather. We crossed Taylor Glacier and endless sheet of ice, which was cut by cracks. I was unafraid and sailed over these bottomless holes. Mr. Muir was delighted that he was not crossing them alone.

    As dusk fell, we reached an enormous crack that was impossible to jump across. In between the two sides was a U-shaped bridge of ice, so thin that one wrong step would mean dropping to your death. Daylight was disappearing, and gusty winds blew snow into my eyes. I turned to return to camp the way we came. However, Mr. Muir decided to cross the crack. He sat down and rode the narrow U-strip as if it were a horse. Once safe on the other side, he called out to me. But I had never been so terrified before. "I am not good at climbing steep slopes." I was scared and thought.

    Then I looked at Mr. Muir, already across on the safe side. Slowly, I began to cross it. I could feel his eyes on me the entire way. Before I knew it, I made the happiest landing of my life. I ran round and round and jumped up and hugged him. From that day on, we spent every moment together.

    Friends should always be honest with you, right? So when they lie, it can be really hard to take. You want to trust your friends and that means knowing that they'll tell it to you straight no matter what it is. Why does this happen?

    One of the biggest reasons friends lie is simply to avoid hurting your feelings. Some people don't understand the difference between being gently honest with a friend and being so straightforward that they leave a verbal wound. They choose to avoid these two extremes in the form of a lie.

    They feel embarrassed.

    Sometimes friends will lie about things in their life because they are too embarrassed to admit the truth. Maybe they are going through a rough time and they just don't want you to know about it. Avoid trying to badger (纠缠) your friends into telling you what's wrong.

    Avoid an argument with you.

    Perhaps your friends know that if they tell you the truth, you'll get angry with them. Make sure that if a friend tells you something unpleasant, you don't overact. If you do end up arguing, do it in a respectable way.

    Exclude you.

    Lying isn't always a sign that friends are trying to protect you, however. When you find out with certainty that your friend is lying to you, try and face it. If you feel your friend is lying because he or she doesn't want to be around you, that's your wake-up to move on.

A. Protect your feelings.

B. They want to be your closer friends.

C. But a friend who lies isn't always trying to hurt you.

D. Consider what's being said and why your friend is telling you this.

E. Being honest and making a sincere effort can keep the friendship strong.

F. Sometimes they lie because they don't want you to be included in their plans.

G. Instead, make it clear that you are there for them when and if they are ready to talk.

    I was a shy girl and I was afraid to talk to people I didn't know. I enjoyed the1 of exploring nature. 2, at school I had to spend all day in the company of others. My3was reading. I spent a lot of time studying and was 4  good grades. My only failure was Spanish — I'd get all As on my written work and tests, but Ds and Fs on the5 part.

    Eventually I went to college. During my third year of college, I had6of being shy and determined to change my outlook and behavior. One day while at school, I noticed an advertisement for7on the local classical music radio station. I had8listening to classical music, and I could easily pronounce names such as Tchaikovsky and Chopin.

    I had no background in radio, and absolutely no hope of getting the job. The idea of9thousands of listeners in "radio land" terrified me. However, I10survived the interview. I was given brief descriptions of symphonies（交响乐）and a public service announcement to read, and a list of composers' names11 . It wasn't hard for me. I left the recording session（录音场次）with a sense of relief and a sense of12. About two weeks later I actually landed the job. It was a13 job, but I grew to14 it greatly. I began to feel comfortable talking to people.

    Although I now spend many hours each week talking with people, I'm15basically a quiet person. Perhaps it is my soft voice and my16nature that helps draw people out when they respond to my questions when I17 them. My former shyness is a18, as I can relate to people who feel discomfortable when they talk to reporters. I still enjoy moments of loneliness and the19found in nature. But I'm also glad I decided to make a20in my life that has opened many doors and opportunities that I never knew existed.

It is widely accepted that optimistic attitudes promote health as well as happiness. The secret of a long life is (universe) desired and has long been sought. Today we can reveal it: always look on the bright side. A huge research project (lead) by scientists at the Boston University School of Medicine concludes that optimists live (long).

Lewina Lee, lead author of the study, said, "A lot of evidence (suggest) that exceptional longevity(长寿) is widely accompanied by a longer span of good health and living disability. Therefore our findings raise an exciting possibility we may be able to promote health and happiness by (develop) positive attitudes such as optimism."

However, the study doesn't suggest that we should aim for great pleasure. Sadness is important part of the human condition. Any normal person sometimes experience disappointment, ambitions and the (lose) of loved ones. But for many people, these matters of human existence (transform) into an abnormal state of despair. There is a vital place in public health for providing mental treatment in helping to correct these cognitive errors. It is not weakness to be defeated by setbacks. It is merely a mistake.

    Perhaps you've heard the old saying "curiosity killed the cat." It's a phrase that's often used to warn people — especially children — not to ask too many questions. Yet it's widely agreed that curiosity actually makes learning more effective. In fact, research has shown that curiosity is just as important as intelligence in determining how well students do in school.

    Curiosity can also lead us to make unexpected discoveries, bring excitement into our lives, and open up new possibilities. In science, basic curiosity-driven research can have unexpected important benefits. For example, one day in 1831, Michael Faraday was playing around with a coil and a magnet when he suddenly saw how he could produce an electrical current. At first, it wasn't clear what use this would have, but it actually made electricity available for use in technology, and so changed the world.

    However, curiosity is currently under the biggest threat, coming from technology. On one level, this is because technology has become so advanced that many of us are unable to think too deeply about how exactly things work any more. While it may be possible for a curious teenager to take a toaster apart and get some sense of how it works, how much do you understand about what happens when you type a website address into a browser? Where does your grasp of technology end and the magic begin for you?

    In addition to this, there's the fact that we all now connect so deeply with technology, particularly with our phones. The more we stare at our screens, the less we talk to other people directly. All too often we accept the images of people that social media provides us with. Then we feel we know enough about a person not to need to engage further with them.

    That means we end up inside our own little bubbles, no longer coming across new ideas. Perhaps the real key to developing curiosity in the 21st century, then, is to rely less on the tech tools of our age.
