Zoos are places {#blank#}1{#/blank#} animals are kept. There are some reasons {#blank#}2{#/blank#} keeping animals in zoos.

    Firstly, zoos are entertaining and interesting places of children. Most children like to see animals in zoos. Zoos also offer people {#blank#}3{#/blank#} (live) in big cities a chance of getting close to nature.

    Secondly, it is easier for scientists to research animals' lives when they are kept in zoos than they are in forests. Scientists can study animals' {#blank#}4{#/blank#} (relate), their life cycles, or their habits to learn how to breed animals, {#blank#}5{#/blank#} can reduce animal {#blank#}6{#/blank#} (extinct).

    Furthermore, the risk of dying out of some {#blank#}7{#/blank#} (endanger) animals is reduced because they are kept in safety.

    {#blank#}8{#/blank#}, zoos also cause some problems for animals, such as restrictions on their freedom. They also lose their “wild” character. For example, tigers might lose their {#blank#}9{#/blank#} (hunt) skills. Besides, zoos cost a lot of money for land, animals' food and labors. This may charge {#blank#}10{#/blank#} (expense) for people who want to visit zoos.

    Do you like trying different things? Are you afraid {#blank#}1{#/blank#} things that you think you're bad at?

    Last year I started to learn t' at chi in order to improve my health and reduce my stress. It was something new for me, and I found it to be quite difficult, very {#blank#}2{#/blank#} (difference) form anything I'd ever learned before. Small {#blank#}3{#/blank#}（move） are important in t' ai chi. I was used to being fast and active ,{#blank#}4{#/blank#}to learn t' ai chi I had to learn patience. Now I've found that I'm a much more patient person than before, and t' ai chi isn't nearly as difficult as it {#blank#}5{#/blank#}(be ) before.

    We tend {#blank#}6{#/blank#}(like) things we are good at — that's normal. For example, I'm naturally very good at badminton and tennis, but I'm very had at anything {#blank#}7{#/blank#}involves keeping balance, such as skating, skiing and gymnastics. T' ai chi has {#blank#}8{#/blank#} (great) improved my balance which has been a very good thing for me.

    My point is that you can keep {#blank#}9{#/blank#}(do) the things you know you're good at and live in your comfort zone, or you can try something new. If you don't try new things, you'll never know what it would be like to try something new. Challenge {#blank#}10{#/blank#} (you). It will definitely pay off in the end.

    Climate change has caused a rise in sea levels. This has increased the amount of salt in fresh water{#blank#}1{#/blank#}(use) on coastal farms. As{#blank#}2{#/blank#} result, farmers are {#blank#}3{#/blank#}(gradual) unable to use fields close to the sea.

    However, Marc Van Rijsselberg, a farmer in the Netherlands is now using a{#blank#}4{#/blank#}(mix) of sea and fresh water {#blank#}5{#/blank#}(grow) healthy and tasty vegetables.

    He teamed up with scientists from the Free University and divided a farm {#blank#}6{#/blank#}eight negated areas. Separate pipes pumped fresh and sea water, and a computer program created water with eight levels of salinity（含盐度）．

    The water levels and the levels of salinity were controlled by computerized measuring devices called "sensors". Mr. Van Rijsselberg said he was able to harvest vegetables from most of the eight testing areas. He said the vegetables were smaller than {#blank#}7{#/blank#}grown in fresh water. But he said they also had more sugar and salt, so they tasted much{#blank#}8{#/blank#}(good).

    He found that potatoes grew better than the other vegetables in the combination of sea and fresh water. Mr. Van Rijsselberg said four kinds of these potatoes would be sent to Pakistan{#blank#}9{#/blank#}thousands of hectares of land {#blank#}10{#/blank#}(damage) by salinization (盐化作用) last year.

    Jack was in his last year of junior school. He was only 4 feet and 11 inches, overweight. He had little hair and few {#blank#}1{#/blank#} (friend). His grade was not {#blank#}2{#/blank#} (good) than his look. His life was going nowhere. He was having a really hard time because his parents recently got divorced (离婚). But he wanted to change {#blank#}3{#/blank#} (he) so that he could have a fresh start in the high school.

    Jack went to Mrs. Collins, his favorite teacher, {#blank#}4{#/blank#} told him that he had to make small changes first and start with the easier things. Jack went to the hospital {#blank#}5{#/blank#} (solve) his hair problems. He started talking to people more to make friends. He realized that he just had to express himself. He started to study more instead of {#blank#}6{#/blank#} (think) about his parents, He {#blank#}7{#/blank#}(begin) to eat healthily to lose weight.

    When Jack entered the high school on the very first day, he was a {#blank#}8{#/blank#} (total) different person. He was now in good shape, smart {#blank#}9{#/blank#} popular. He also had a nice hairstyle. Everyone wanted to make friends {#blank#}10{#/blank#} him. More importantly, Jack finally became happy and confident through his own efforts.

    I am Adam Rouse. I first {#blank#}1{#/blank#} (buy) cannabis(大麻) from a man in the street and continued to buy cannabis from him for six months and as a result, I got addicted to it. One day, the man offered {#blank#}2{#/blank#} (I) some crack cocaine, a more {#blank#}3{#/blank#} (power) addictive. When I went back to the man for more crack cocaine, he asked me {#blank#}4{#/blank#} a lot of money. {#blank#}5{#/blank#} (terrible), I was in pain when I couldn't afford to buy any drugs. {#blank#}6{#/blank#} (get) money, I broke into a house and stole something to sell for money. The more drugs I took, the more addicted I became. So I had to steal something every day to pay for the drugs. One day, I {#blank#}7{#/blank#} (catch) stealing and sent to the police station. The next day, {#blank#}8{#/blank#} doctor came to see me and told me that I could die {#blank#}9{#/blank#} I could stop taking drugs. I took his advice and stopped immediately. Now I work in a center for drug addicts, helping others to stop {#blank#}10{#/blank#} (take) drugs.

How to Become a Morning Person?

You have grand ambitions: to start a business, to write a book. But chances are you work long hours, or household responsibilities consume your days. By the time you finish all you have to do, you will have had no energy {#blank#}1{#/blank#}anything you want to do beyond turning on the TV.

Yet some busy people do make time for their priorities. The secret is giving the most attention to {#blank#}2{#/blank#}at the very beginning of a day. They get up earlier than they have to. Morning by morning, they make progress on something {#blank#}3{#/blank#}matters.

It's not fun to force yourself out of bed, but these early hours are often the best time to do things for yourself. With a little schedule reorganization, {#blank#}4{#/blank#}(become) a morning person is more doable than you think.

I first learned that mornings {#blank#}5{#/blank#}be transformational years ago, when I was studying a busy lawyer's schedule. She wanted to spend more time with her son, but she had little control over when she left work. This state of affairs kept her sad {#blank#}6{#/blank#}she realized she and her son were both early risers and the morning time could be made full use of. After thinking it through, the lawyer decided to get up even earlier. Then, when the boy stepped into the dining room, she {#blank#}7{#/blank#}(finish) preparing a rich breakfast so they two could enjoy the meal to the fullest together.

Mornings are also great for focused thinking. Getup an hour earlier, and you can knock out your most important task of the day. Or you can spare some time for those creative desires {#blank#}8{#/blank#}(bury) deep in your heart and hard to nurture.

But many will argue：I'm not a morning person! The fact is that there are not so many true night owls. When most people take an honest look at {#blank#}9{#/blank#}they're spending the hours before bed, they'll find they have wasted much time on the TV programs they don't mean {#blank#}10{#/blank#}(watch). Also, they often browse through photos on social media of people they didn't like in high school anyway.

A better approach is to sleep earlier, rise earlier and turn unproductive evening hours into productive morning hours.
