I learned all about taking responsibility from my mother’s tough love. My mom had a wonderful way of helping you        up and realize that your life is going to be what you make it.
She had this circular way of      you took responsibility for your decisions and the person you would      . She would say,“ It' s your      .”      “What you want and what you get are sometimes two       different things.” And then, “No one ever said life was fair.” And she would      these comments together in such a way that you could never      an argument, and yet, the      was that you realized your life is going to be what you make it.
So I might go to my mom and say, “I’d like to      football”. And she would say, “Well, it's your life. If you want to go out there and get      and hurt and break your knees and limp around the rest of your life, that' s fine.” That is      I would say, “Well, you know, that won’t       . I' m really fast.” And she would reply, “Well, we don’t really have the money.” And then I would     , “Yes but that' s not fair.” And she would reply, “ Well, life isn’t      .” Then I would say, “But I’ve been itching to." And she would reply, “Yes, but what you want and what you get are usually two entirely different things.”
It was the combination of these       that allowed my mother to lead me down the right path under her      but let me feel as if I was making the decisions      my own. The sum total of that    was, in the end, you’re      for the life you lead. That' s the best advice I’ve ever gotten.

Do you know some people who just have all the luck? They seem to get all the       and you ask yourself: “Why don’t I get    ? Why don’t I get a great education?” But the real reason why most people are successful or lucky is that they’ve learned how to       themselves in a place so they can be lucky. They’ve learned how to, in a way,       their own luck!
I’m not       about dishonest or illegal ways. I’m talking about hard,       work. But successful people work smart. They keep improving and making the most of their abilities. Yet they also learn to      for help in things they themselves are not that good       doing. So we not only must make the most of our own special strengths, we must also learn our       and weaknesses.
A man recently got his lucky big break. Everyone said, “That guy’s so lucky!” But that man created his own luck       by arriving at the office early. He apologized and       when he was wrong. He even shared the credit and reward with others       he had done much of the work. He was never satisfied just to get       and do average work. He always       the extra effort to do his very best.
We have to work hard and do what it      to be on the way to luck and success when it comes.        , weMI miss it because we aren’t ready. You never know when the right opportunity will come your way, and when the right, important person is watching your excellent        and work. That’s when you’ll get your lucky break! But when you put your life in Jesus Christ’s         , the right important person is always         you and all that you do. Then he will      and bless vour life in manv wavs as vou do vour very best to please him in every thina every dav.

In the doorway of my home, I looked closely at my 23-year-old son, Daniel. In a few hours he would be flying to France to   36  a different life. It was a transitional(过渡的)time in Daniel's life. I wanted to    37  him some words of significance. But nothing came from my lips, and this was not the    38  time I had let such moments pass.
When Daniel was five, I took him to the bus stop on his first day of kindergarten. He asked, “What is it going to be like, Dad? Can I do it?” Then he walked   39  the steps of the bus and disappeared inside. The bus drove away and I said nothing. A decade later, a similar   40 played itself out. I drove him to college. As I started to leave, I tried to think of something to say to give him    41 and confidence as he started this new stage of life. Again, words 42  me.
Now, as I stood before him, I thought of those 43  opportunities. How many times have I let such moments   44 ? I don't find a quiet moment to tell him what they have  45  to me. Or what he might   46  to face in the years ahead. Maybe I thought it was not necessary to say anything.
What does it matter in the course of a lifetime if a father never tells a son what he really thinks of him?    47  as I stood before Daniel, I knew that it did matter. My father and I loved each other. Yet, I always   48  never hearing him put his   49   into words. Now I could feel my palms sweat and my throat tighten. Why is it so   50  to tell a son something from the heart?
My mouth turned dry, and I knew I would be able to get out only a few words clearly. “Daniel,” I said, “If I could have picked, I would have picked you.” That's all I could say. He hugged me. For a moment, the world    51 , and there were just Daniel and me. He was saying something, but tears misted my eyes, and I couldn't understand what he was saying. All I was    52  of was the stubble(短须)on his chin as his face pressed   53  mine. What I had said to Daniel was   54 . It was nothing. And yet, it was  55 .

Cloning techniques were ____ to the production of the pigs.Genes can only be knocked out(去除) in a single cell.Cloning of these single cells then allowed the ____ of a whole animal in which the gene was knocked out in every cell.But the PPL researchers have ____ in knocking out only one copy of the gene.The team will now attempt to knock out both copies of the gene.
The team will also ____ tests to investigate whether a virus from the pigs could infect human cells.“Although a lot of the work is very ____,we’re still very far off being able to grow an organ,” says Julia,who is working on this project and quite ____ to creating similar knock­out pigs with researchers at the University of Missouri.
