{#blank#}1{#/blank#} The Center for Injury Research and Policy at Nationwide Children's Hospital in Ohio did the study. It was published in the American Journal of Preventative Medicine. The study found a sixty-three percent increase in the number of people treated for rock climbing injuries in American hospitals.

    The study said forty thousand people were treated in emergency rooms. {#blank#}2{#/blank#} The ankle was the most common body part to be injured.

    {#blank#}3{#/blank#} The average age was twenty-six. Fifty-six percent of the injuries were to people twenty to thirty-nine years old. Women made up twenty-nine percent of the injured population. That is more than that in past rock climbing studies.

    {#blank#}4{#/blank#} But many people think it is worth it. John Bachar said rock climbing felt like being on another planet. Dean Fidelman says it is a continual challenge and a beautiful form of movement. And, for Sarah Bowman, she has just started her way up the rocks.

    Dean Fidelman said that he believes a climber's ego(自我价值感) can be his worst enemy on a rock. {#blank#}5{#/blank#}

How to improve your vocabulary

    Vocabulary is a key part of learning a new language. {#blank#}1{#/blank#}  Maybe you can't learn a hundred new words a day, but you can learn one or two a day, totaling thousands of new words over the years. Here are some tips for building up your vocabulary.

    Make a plan to learn new words. If you want to improve your vocabulary more quickly, you have to make at least a small promise. {#blank#}2{#/blank#}

Make you vocabulary practical（实用的）. {#blank#}3{#/blank#} For example, learn more of your trade language—- the words that are commonly used in your business or hobby or vocation(职业). Find better, fresher, clearer words to express what your friends are talking about.

    {#blank#}4{#/blank#} As you read, if you come across a new word that you don't understand. Don't miss it. Take the time to look it up in a dictionary. Write it down and use it later.

    When you learn a word, use it immediately and frequently. Put your new word into conversation with as many different people as you can. {#blank#}5{#/blank#} Use it in sentences. Write it on a card and practice it while waiting for red lights.

A. Repeat it to yourself.

B. They're highly reusable

C. Start learning where you are.

D. Decide to learn one new word every day or two.

E. When you're writing something, use a dictionary frequently

F. Start by learning the words that can express what's most important to you.

G. The more you read, the more words you'll see, and the more you'll understand.

    It could happen anywhere at any time.{#blank#}1{#/blank#} Most people, at one time or another, have been on the receiving end of a random act of kindness. In a sometimes cold world where people can be so focused on what they're doing, a random act of kindness can make all the difference.

    They can be relatively insignificant. Hannah Bailey from London, for example, told the Metro newspaper about how she was given her fruit and vegetable shopping for free. The seller did her a kindness when it emerged she didn't have any change to pay.{#blank#}2{#/blank#}

    The city of Naples has long had a tradition called' caffè sospeso'. When buying coffee, a person who has recently been lucky would purchase two cups but only drink one, leaving the second one anonymously(匿名), out of the goodness of their heart, for a poor person to claim for free.{#blank#}3{#/blank#}

    However, in some cases, these little acts can be a matter of life and death. Take, for example, the unnamed commuter, who in June 2018 fell off a station platform onto an electric railway track in Toronto, Canada. A quick-thinking, hut even now unknown, bystander selflessly leapt down to pull him to safety.

    So, why do it? {#blank#}4{#/blank#} The people never meet again. According to UK charity The Mental Health Foundation, acts like these can “give our lives new purpose, show us other perspectives on our own problems and even make us feel content.”

    {#blank#}5{#/blank#} Hold open a door for someone, deliver a compliment—even give up your seat on a bus. Help someone who is in need. It takes all kinds. It needn't be anything huge. One day, whether you need it or not, someone might help you in your hour of need.

A. So give it a try.

B. Be brave to face challenges.

C. Often, the acts aren't paid back.

D. She was happy about it all day.

E. She was in low spirits the whole day.

F. This tradition is now more common worldwide.

G. It's often unexpected, but almost never unappreciated.

    The first Thursday in May is World Password Day, but don't buy a cake or send cards. Computer chip maker Intel created the event as an annual reminder. {#blank#}1{#/blank#}.

    The purpose of a password is to limit access to information. Having a very common or simple one like "abcdef" or even normal words like "password", is barely any security at all. {#blank#}2{#/blank#}. Hackers' password cracking tools take advantage of this lack of creativity and get in our accounts easily. More experienced users would choose a less common password. However, they might still fall victim to cracking software.

    {#blank#}3{#/blank#}? A secure password is all that stands between us and a cybercriminal. It should be unique and complex which a hacker can't easily guess or crack. The best passwords are supposed to be at least 15 characters long and full of random numbers and letters. However, a long password means a complicated process to log into a website. {#blank#}4{#/blank#}. You may want to write it down, but it is not suggested due to risk.

    Then what should we do? {#blank#}5{#/blank#}. You can choose a phrase such as "I want to go to England." Next, convert it to an abbreviation (缩略语) by using the first letters of each word and changing the word "to" to "2". Then you get following password phrase: iw2g2e. You can make it even more complex by adding punctuation, spaces or symbols: %iw_2g2e!@. It is much easier to remember and safer.

    Can't wait to try? Let's say goodbye to "666666" and change your password right now.

How long does a year last?{#blank#}1{#/blank#}Your parents might say that a whole year can pass―in the blink of an eye. Why does time seem to pass faster as we get older?

{#blank#}2{#/blank#} This physical change causes the rate at which we take in and process new information to decline. Babies, for example, move their eyes much more often than adults because they're processing images at a faster rate. They take in a lot of information and do many things in a single day.{#blank#}3{#/blank#}However, as people's brains degrade over time, fewer images are processed in the same amount of time. Therefore, older people receive less information during a day than younger people. This causes things to seem as though they're happening more quickly.

{#blank#}4{#/blank#}People may measure time by the number of memorable events that can be recalled within a certain period. Have you ever noticed that when you recall your firsts, they seem to be in slow motion? That's because when something is a first, there are many exciting things to remember. Recalling these memories makes you feel like they took forever.

For many adults, life is routine. When they look back, they might feel like there are not many novel things to remember.{#blank#}5{#/blank#}

A. Children might say that a year lasts forever.

B. Different people have different feelings toward time.

C. Therefore, time seems to be moving faster to them.

D. As we grow older, we become less interested in new things.

E. This makes them feel like a single day lasts for a long time.

F. According to scientists, our brains degrade and change over time.

G. In addition, people may also feel time differently due to psychological reasons.
