    Wherever in the world you’re reading this right now, you will be aware of just how mixed modern society has become in terms of race. Within the UK, mixed-raced children are the largest   1  ethnic minority. Bringing home a partner of a different   2  to yourself is no longer viewed as, “strange” or “different” in a lot of families. When Joseph brought home Hari, the   3  that she was of Indian parentage was never even talked about — she made him happy. They made each other happy. And that was all that   4 .
    But the reason why they were together for 11 years before they got   5  is that Hari was afraid of telling her   6  about the person that she’d fallen in love with. She was afraid of the consequences it would   7  for her younger sisters. Would they be packed off to India? Would they end up in arranged   8  they may not want? At 22 years old, when she first fell in love with him — it was a large burden to   9 .
    But she loved him, and   10  they moved in together… and then bought a house by the Brighton coast, where they have   11  for almost 8 years. All the while her parents didn’t know. Her sisters did, and they too loved Joseph — they   12  him as the brother they’d never had.
    But after nine years together, she finally had to tell her father (her mother   13  away a few years ago). We were on tenderhooks（惶恐不安）the weekend she went up North to tell him.
    It was emotional and as a family we were worried. Hari had been   14  of our family for so long, we felt for her. We knew how   15  it would be. She loved her father, but knew this would hurt him, who was a very traditional Sikh man.

    At about 4 am, after hours of being unable to sleep, of shivering in the cold mountain air and trying to silence my crying kids who kept waking up, of attempting to find a comfortable sleeping position, of listening to whether there might have been a bear outside our tent, I finally couldn’t stand it any more. I complained, “Everything has gone wrong.”
    My wife and I were in one tent with our two young kids. A hundred yards east away was Summit Lake, where the glorious early morning mist was shimmering（闪烁）off the water. A couple miles to the southwest was the base of the Lassen Peak Trail. The base was 8,000 feet above sea level, and huge snow dotted the scenery even in mid August. Further west still was Bumpass Hell, with steam rising up.
    As the sun crept up over the edge of the Lassen peak, we fired up the camp stove and had breakfast. Half an hour later, my six-year-old daughter and I were in the parking lot of the Lassen peak trail, getting ready to go up the mountainside. We wouldn’t make it all the way, but it didn’t matter. We would see nature at its extremes: the volcanic ash that layered on the earth turning the melting snow a mysterious pink as the sun struck it; the blues of the sky shading into the blues of distant lakes, which in turn shaded into the whites and grays of the snow.
    My daughter grabbed my camera. She wanted to take a photo of “the composite（混合物）”of colors. Looking out over that scenery, and seeing my daughter fascinated by nature, I felt stupid about my morning complaints.
    Yes, camping is uncomfortable. And yes, there’s a lot to be said for getting out a credit card,reserving a room in a nice hotel, and going out for a fancy meal. But there’s also something wonderful about being so close to raw nature. And , as important, there’s something vital about getting young children out of their increasingly modern comfort zones and forcing them to meet the world around them.
    小题1:.According to the passage, what contributed to the author’s sleeplessness ?
    ①the cold weather       ②his crying children          ③fear of bears            
    ④sounds of bears      ⑤the aches of his lower back      ⑥his own complaints
    A．①④⑥B．①②③C．②④⑤D．②③⑤
    小题2:.Which of the following maps correctly shows the places ?

    小题3:.The underlined word “colors” in Paragraph 4 refers to ______ .
    A．blue, white, gray and pinkB．white, yellow, gray and pink
    C．white, green ,gray and pinkD．blue, green,white and gray
    小题4:.How did the author’s feeling change from the beginning to the end ?
    A．Calm→Satisfied.B．Excited→Frustrated.
    C．Sad→Calm.D．Regretful→Satisfied.
    小题5:.Which of the following statements can be inferred from the passage ?
    A．Nature is the glass reflecting truth.
    B．Nature is the best scenery designer.
    C．The journey of a thousand miles starts with one step.
    D．A bad beginning makes a bad ending.

    LAST weekend, I helped my friend Alex get money for poor children at Crossroads Mall He  36 needed volunteers, especially of the female. I decided that this was a pretty good  37 , so the next day I got ready to go.
    I arrived at Crossroads about five minutes  38 , and helped Alex and   39 of the volunteers. There were only three  40 at first, and we figured we might as well get started  41 just waiting for more to arrive. I held the   42 , and suddenly felt extremely shy. I did not  43 asking people for donations. In fact, I’m usually one of those people who try to   44 those boring stands and ask you for a little contribution. For heaven’s sake, I can contribute to a few,   45 I cannot alone  46 every single cause in the world!
    I really didn’t like the idea of asking anyone for donations to our cause.   47 , I watched my friends speak to the strangers, and noticed that they were extra polite to everyone—no matter whether they  48 . I realized that   49 I wasn’t pushy（强求的）, it would be okay, and my conscience could be  50 .
    I pasted on a large smile, and started asking people passing by. My mouth tripped over words, and I continually said “um” while I thought of the correct terms.   51 I talked to more and more people. Not only improved, but also started noticing small  52 . Instead of saying “donate”, which made most people walk away  53 .I started suing the word “contribute”. I added the phrase “every little bit counts”, and people started to donate small amounts in larger quantities. As the day went on, I learned how to pull on the hearts of the   54 , and I became a successful fundraiser.
    At the end of the day, we all gathered at Alex’s house and   55 how much money we raised. I was so surprised; We raised over $300! We celebrated, and went home tired, but satisfied that we helped a great cause.

    When a dirty and untidy orange cat showed up in the prison yard，I was one of the first to go out there and pet it．I hadn’t touched a cat or a dog in over 20 years．I spent at least 20 minutes，knelt down behind the kitchen as the cat rolled around，relaxed．What he was expressing outwardly, I was feeling inwardly．It was an amazing bit of grace to feel him under my hand and note that I was reaching a life or another creature with something as simple as my care．
    Over the next few days，there were other prisoners responding to the cat．Every yard period，a group of prisoners gathered there．They stood around talking and taking turns petting the cat．These were guys you wouldn’t usually find talking to each other．Several times I saw an officer in the group，not chasing people away, but just watching and seeming to enjoy along with the prisoners．Bowls of milk and water appeared along with bread, wisely placed under the edge of the dustbin to keep the birds from getting it．
    The cat was obviously homeless and in pretty bad shape．People said that the cat came to the right place．He's getting treated like a king．This was true．but as I watched I was also thinking about what the cat was doing for us．There was a lot of talk about what's wrong with prisons in America．We need more programs．We need more psychologists or treatment of various kinds．Some may even talk about making prisons more kind．But I think what we really need is a chance to practise our own kindness．Not receive it，but give it．After more than two decades here，I know kindness is not a value that's encouraged．It's often seen as a weakness．
    Instead，the culture encourages keeping your head down，minding your own business，and never letting yourself be weak．
    The cat did my heart good to see the effect he had on me and the men here．By simply saying，”I need some help here”，he did something important for us．He needed us．And we needed to be needed．I believe we all do．

    When you leave school，you can breathe sigh of relief and leave learning behind，right？Wrong！Learning should last a lifetime. You exercise your body to stay strong，and you should exercise your mind to stay sharp.

    An English idiom says，“You can’t teach an old dog new tricks.” But scientists have discovered that isn’t true. Older people can learn，and they should，in order to keep their brain active. Now a new trend has begun in several states in the US that encourages learning. Adults can attend One Day University. They can spend a Saturday or Sunday hearing four 70-minute lectures. Each one is given by a top university professor. One of the original participants said，“It’s like a health club for the brain.” Also，universities like MIT have made all of their courses and lectures available online for free！Libraries offer learning programs too. With so much available，there is no excuse not to learn!
    Learning is a habit. Don’t leave it behind after you leave school. On the website lifehack.org，author Scott Young mentions several things to help you.
    Always have a book. It doesn’t matter if you read fast or slow. Just read. If you read just one book a week，you’ll read 52 over the course of a year. Think of the knowledge you’ll gain!
    Practice it. As you read，do something with what you’ve learned. Don’t just enjoy the mental exercise. Use the knowledge. If you read about painting，try it!
    Make a “to learn” list. Compose a “to learn” list for yourself. Maybe you want to speak better English，play the piano，or cook French food. Whatever interests you，put it on your list and then make the time to do it.
    Teach others. Whatever you learn，teach someone else. You’ll not only help others but also understand what you’ve learned.
