Giraffes are beautiful, smart and friendly. They have long legs and necks (脖子). They are so tall that they can grow up over 5 meters (米). So how do they sleep or drink?

    You may think it's difficult for them to sleep, but they have no such problems because giraffes don't often stop for a sleep. Giraffes just need to sleep about thirty minutes a day. When they sleep, they don't always lie down (躺下). They usually sleep for minutes at a time, because it's difficult for them to get up again. And it's a great danger to sleep in the wild (荒野). But the giraffes in the zoo sleep for about 4-6 hours every day. They usually lie down when they sleep.

    Drinking water is a big problem for giraffes because their long necks are too "short". To drink water, they must spread (伸展) their front legs in a difficult way. And in this way, other animals like Africa's big cats can easily hunt (猎食) them. So they usually get most of their water from the trees and flowers. Giraffes don't need to drink water very often. They can even drink no water for months!

Nowadays in school life, a lot of students develop a fear of tests. It's not because tests are something to be afraid of. Most students are afraid of tests mainly because they don't always think they are well—prepared and they don't have enough self—confidence. If you follow the advice below, it's not difficult to overcome your fear of tests.

People who know that they are not well—prepared are usually those who fear tests most. However, most students don't know when they are truly prepared for a test. As long as you know that you have studied well and long enough, you have reason to believe that you are well—prepared.

Be confident about yourself. Confidence before a test can bring about two results: either you fail the test and feel as if your confidence was unfounded (毫无根据的) or you could actually do well in the test because of your confidence. Some students find that they experience the first result. However, this is only because those students might not have followed the first advice mentioned above. As long as you have studied well, you will be more confident of your chance to succeed in a test. If you feel as if you have not studied hard enough, then you will not be as confident as you should be.

Ask your teacher in advance (提前) about the material that is going to be covered in the test. In this way, you will know what you should prepare for and you can get confidence in the test. But you have to be brave enough to ask. Most students do not ask unless their teacher gives the information first, so make sure that you ask.

You should know that tests are only telling if you have got the knowledge, not how good or bad your IQ is. So, even if you do badly in one test, you should know that there are other tests to come. As long as you think that there is another tomorrow, you can overcome your fear of a test. However, make sure that you are going to prepare well for the other tests.

Fear can be a problem in the process of achieving success. However, with the right attitude (态度) and preparations, you can overcome your fear of tests by using these suggestions.

Here is a story: A man sees a butterfly (蝴蝶) . The butterfly tries to get out of its chrysalis (蛹) . F{#blank#}1{#/blank#}sorry for it, the man decides to help. He cuts the chrysalis and the butterfly comes out e{#blank#}2{#/blank#}. Surprisingly enough, the butterfly is unable to fly.

When people are young, meeting and overcoming challenges will make them s{#blank#}4{#/blank#} and ready to face life.

When we look at successful people, we see that the most successful of them are people who have had to struggle.

One famous businessman, who now o{#blank#}5{#/blank#}many big supermarkets, used to carry clothes on his back and sell them from door to door when he was young. Another successful man is Dennis. His father died when he was only twenty. He had to b{#blank#}6{#/blank#}up a big family. He took up the challenges and overcame them. Today his brothers and sisters are leading s{#blank#}7{#/blank#} lives.

Sometimes challenges do not appear to us because we keep away from them. So, some parents and teachers actively encourage young people to face challenges. They might organize some a{#blank#}8{#/blank#}for young people which provide them with challenges, like rock—climbing, camping, volunteer work and so on. However, just passing exams will not prepare a person for life. We must meet and overcome challenges. The young people of today will become the leaders of t{#blank#}9{#/blank#}.

    You might not pay much attention to whether the things you say on WeChat and other online messaging apps are recorded. But a regulation (规定) that went into effect on May 1 will make everything you say online usable against you in a court of law (法庭).

    According to the Supreme People's Court's regulation, text messages, emails, and content posted on websites or instant (即时的) messaging platforms can be used as evidence (证据) in civil lawsuits (民事诉讼).

    The idea of digital evidence was first introduced as part of China's Civil Procedure Law in 2012. However, the recent regulation has made it clearer.

    "This is the first time the Supreme People's Court has clarified (阐明) the scope of digital evidence, especially on social media platforms and instant messaging services," Li Ya, a lawyer in Beijing, told China Daily.

   The regulation was introduced to keep up with changes in social development. Social media activity has become a part of most people's lives. Therefore, digital evidence is playing an increasingly important role in civil and criminal lawsuits.

    According to the regulation, if people plan to use digital evidence in a lawsuit, they have to first prove that they use the app or website that the evidence comes from. Second, they must provide an original (原始的) and complete record of the evidence. For example, if you lend somebody money through WeChat, you must keep the original transfer (转账) records and conversations on the app.

    However, there are still questions about the regulation. Some point out that the regulation will not necessarily help in every case. "How to make sure a microblog was actually posted by the micro blogger is a challenge," Li said.

    As more information comes out about 10-year-old Cindy Smith's death(死亡), worries about amusement park safety(游乐场安全性) grow.

Cindy is not the first child who died on an amusement park ride. 25 years ago, the mother of a 14-year-old girl waited to pick up her daughter outside Worlds of Fun. Laura Barry never saw her daughter Rosie alive again.

"My heart goes out to the Smith family more than they can ever possibly know," said Barry. She is one of the few people who truly know the hurt that family is feeling.

In 1995, Rosie's mom said that something went wrong on the Timber Wolf the night Rosie died. Police found no evidence(证据). Two men told the police that they saw Rosie standing before she fell out of the car.

"I couldn't believe that such a thing could happen still and again," said Barry. She believes Rosie's death should have been a wakeup call for amusement park safety.

She finds that not much has changed in the past years. Amusement parks race to build bigger, taller, faster rides. In her opinion, amusement parks just try to bring in visitors and give them the idea that riding is good, safe and fun. She believes that parks should have put safety first.

There is no exact number of amusement park deaths each year. It is quite low according to some websites. But Barry doesn't accept that. "My daughter was the only person that had ever been killed at Worlds of Fun in all of the years, among all of the thousands and thousands of people that went there. The number doesn't mean anything, you know, because when your child is the one, that's one too many," she said.
