Tower Bridge is one of London's most striking {#blank#}1{#/blank#} (attract) that you shouldn't miss when visiting the capital. This magnificent piece of Victorian architecture {#blank#}2{#/blank#} (date) back to the late 1880s, and until the mid - 1970s the main bridge {#blank#}3{#/blank#} (operate) by a steam engine.

    Today Tower Bridge is a splendid landmark typical of London,{#blank#}4{#/blank#} (surround) by cafes, and bars where tourists and locals alike can sit and enjoy the beautiful bridge,{#blank#}5{#/blank#} looks like two small castles over the Thames, just like something out of a fairy tale.

    It is free to admire Tower Bridge and walk on it {#blank#}6{#/blank#}any time; it's striking to look at during the day and magic when lit up at night,{#blank#}7{#/blank#}don't miss out on this wonderful scene!

    If you'd like{#blank#}8{#/blank#}(step) inside the towers of the famous bridge, you can book Tower Bridge Exhibition tickets. During the exhibition, you can visit the famed engine rooms and impressive towers and find out {#blank#}9{#/blank#}the bridge came into existence through digital displays. You can also pay {#blank#}10{#/blank#} visit to the glass room of Tower Bridge on the high - level walkways. There are even yoga classes available on the glass floor of Tower Bridge!

    There has been a recent trend in the food service industry toward lower fat content and less salt. This trend, which was started by the medical community（医学界）{#blank#}1{#/blank#}a method of fighting heart disease, has had some unintended side{#blank#}2{#/blank#}(effect) such as overweight and heart disease-the very thing the medical community was trying to fight.

    Fat and salt are very important parts of a diet. They are required{#blank#}3{#/blank#}(process) the food that we eat, to recover from injury and for several other bodily functions. When fat and salt{#blank#}4{#/blank#}(remove) from food, the food tastes as if is missing something. As {#blank#}5{#/blank#} result, people will eat more food to try to make up for that something missing. Even {#blank#}6{#/blank#} (bad), the amount of fast food that people eat goes up. Fast food{#blank#}7{#/blank#} (be) full of fat and salt; by {#blank#}8{#/blank#} (eat) more fast food people will get more salt and fat than they need in their diet.

    Having enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and will improve the taste of your food. However, be {#blank#}9{#/blank#} (care) not to go to extremes. Like anything, it is possible to have too much of both, {#blank#}10{#/blank#} is not good for the health.

David will never forget what happened to him the day before yesterday. He was eating something at home{#blank#}1{#/blank#} he received a strange phone call from a hospital. The caller said that his son{#blank#}2{#/blank#}(fall) to the ground unconscious on the way to school. It was he {#blank#}3{#/blank#}took him to the hospital. David hung up his cell phone and rushed to his son's classroom, only to find him listening to the teacher attentively. He suddenly realized that he had been cheated, but he felt {#blank#}4{#/blank#}(relieve). Just at that time the phone rang again, saying, "Your son is in great danger and he needs {#blank#}5{#/blank#}immediate operation which costs 48,000 yuan. The doctors here say they will not operate {#blank#}6{#/blank#}your son until they receive the money." When{#blank#}7{#/blank#}(ask) from where the caller had taken his son to hospital, the caller rang off. David gave a big smile and said. "What a pity!"

If the cheater thought he could get money from David in such a（an）{#blank#}8{#/blank#}(honest)way, he was wrong. Such phone calls are common these days. A few of them might have fallen victims to such tricks. Most parents are sensitive to {#blank#}9{#/blank#}. It was really silly to cheat well—educated men like David.

    Believe it or not, it's a true story. The{#blank#}10{#/blank#}(colleague)in his office can confirm it, such as Tom, Peter and so on.

    Is there such a thing as being "over-protective"?

    I can honestly say that my answer to that question {#blank#}1{#/blank#}(change) dramatically(戏剧性地)since I became a parent.

    Before the birth of my daughter, I taught at{#blank#}2{#/blank#}private school, often viewing my students as over-protected, worrying  {#blank#}3{#/blank#}would happen when they went on to middle schools.

    Some did fine, and some did not. Some needed constant pats on the back, words of  {#blank#}4{#/blank#}(inspire) and extra support, which I {#blank#}5{#/blank#}(happy) gave. Others were content on their own, needing little {#blank#}6{#/blank#} no interaction(互动)with their teacher.

I'd always supposed their parents were over-protective, for they were the ones that still walked their  {#blank#}7{#/blank#}(five) graders into the classroom and met them at the school gate.

    Admittedly, I laughed at those parents, {#blank#}8{#/blank#}(think) their children would never learn to be  {#blank#}9{#/blank#}(independence) if they didn't let go just a little. Then I had my own daughter. The moment I looked at her little face, I {#blank#}10{#/blank#}(know) I'd do everything in my power to protect her and make sure she always felt safe!

The college entrance examination is just around the corner. {#blank#}1{#/blank#} (assign) and tests will keep many of you up late at night, and you may plan to make up for your{#blank#}2{#/blank#} (lose) sleep during the weekends. But is it useful?

A study shows that the habit of sleeping in{#blank#}3{#/blank#} weekends doesn't fix the damage done by a lack of sleep during the week. Even {#blank#}4{#/blank#} (bad), it may damage your health.

In the study, {#blank#}5{#/blank#} was conducted over 10 days, 36 healthy young men and women with different sleep requirements {#blank#}6{#/blank#} (divide) into three groups. The researchers found that people who lacked sleep ate more snacks and gained {#blank#}7{#/blank#} (weigh) quickly. That could be partially due to the shifting of the{#blank#}8{#/blank#} (biology) clock and changes to certain body hormones especially hunger hormones.

And {#blank#}9{#/blank#} they tried to sleep for as long as they wanted to on weekend, it was still insufficient(不够的) to meet standard sleep time because they found it difficult to fall asleep. Moreover, they were more likely{#blank#}10{#/blank#}(show) increased sensitivity (敏感性) to insulin(胰岛素) in both their muscles and their livers.
