(risk) their own. I cried today near the explosion site, not because of the smoke from the ongoing fire 6. because of a short message a firefighter sent to a trusted friend that went viral online. It reads, “If I cannot make it, my father is 7.(you); and please remember8.(sweep) my mother’s tomb.” I was thrilled later to learn that he did make it.
“Everyone knows it’s 9. (danger) to be a firefighter. But he has always liked it and has done it for 12 years,” his father said. “He survived this time, but no one knows what10. (happen) next time.”

It's important to learn how we can protect the environment. Here are 5R rules for us.
Reduce. If you want to reduce waste, you should use things more wisely.1. If everyone uses paper carelessly, soon we would not have any trees left. Other things are also being wasted, and people don't know what to do with the waste in big cities. So it is necessary to reduce the amount of waste we produce.
Reuse. You should always think of reusing things before throwing them out. For example,2.. In a family, you may pass on such clothes to younger brothers or sisters.
Recycle. Bottles, cans and paper can easily be recycled. By doing so we can save lots of time and money. For example,3.. The metal can be used to make new coke cans.
Recover.4.. You have two choices: one is to throw the apples away, the second is to throw the rotten ones and keep the good ones. In this way, you are recovering the eatable parts of food.
Repair. If one of the legs of your table is broken, you should repair it. If you want to buy something newer and better, it is better for you to sell the old table, or 5.
Learn the rules to protect our environment. Let's try our best to make the earth cleaner and more beautiful.
A. give the clothes you do not use or the ones which are too small to the poor.
B. coke cans are sent to a factory, where they are smashed flat and melted.
C. A large number of trees are being cut down to make paper.
D. Trees are planted every year.
E. give it to people who can use it after repairing it.
F. don’t throw it away if you can use it.
G. When you buy a box of apples, there may be a few rotten ones.
Humans were designed to stand upright. And yet in this modern world, too many of us spend our days with our heads lowered for a simple reason: we’re staring at the tiny screen of a smart phone.
People spend an average of 2 to 4 hours each day with their neck bent while shooting off emails or texts. That’s 700 to 1,400 hours a year. The success of social media has led to a rapid development of bad smart phone posture（姿势）.
The average adult head weighs 10 to 12 pounds when it’s in the upright position. However, because of the gravity, bending your head at a 15 degree puts 27 pounds of pressure on your spine(脊椎)；a 30 degree neck bend could equal 40 pounds of pressure; a 45 degree bend adds the force of 49 pounds, according to the research from Dr. Kenneth Hansraj from New York. These stresses may lead to many problems.
It’s no secret that correct posture is better for your back. According to the researchers, good posture is described as ears aligned(成一条直线) with the shoulders. In proper alignment, spinal stress disappeared. It is the best position for the spine. Standing tall doesn’t just make you look better; it improves your health, too. Other studies have found good posture has even been connected to ways of behaving. People who have poorer posture often have poorer physical and emotional health.
The researchers describe bad posture as “the head in a forward position and the shoulders dropping forward in a rounded position”. Bad posture has been connected to many medical problems, including headaches and other problems, depression and heart disease. This is why Hansraj said it’s important to be mindful of your smart phone posture. Though it is nearly impossible to avoid the technologies that cause these problems, people should make an effort to look at their phones with a correct posture.

Living in the wild can be hard．Finding food and staying safe aren't easy．Each day, animals try to survive in their habitats．Not all animals get by on their own. Some animals form a close partnership with other kinds of animals．These pairings are called symbiotic(共生的)relationships．
In a symbiotic relationship, the animals depend on each other．One animal helps the other meet its needs．Sounds good, right? Not always．Some animals are not very kind to their partners．In some cases, one animal meets its needs but hurts its partner．Take ticks(扁虱), for example．These insects suck blood to live．To get blood, they attach themselves to other kinds of animals．Ticks can pass germs（细菌）that cause disease instead of helping their hosts．
In other relationships, animals don't treat their partners so poorly．Both animals benefit from living with the other animal．
Small animals called cleaner shrimps(清洁虾）have found a way of helping fish．As their name suggests, the shrimps clean the fish．They hang out at what scientists call a cleaning station．A fish stops by．Then a shrimp climbs onto the fish and even steps into the fish's mouth．The shrimp uses its tiny claws to pick stuff off the fish's body．That can include dead skin and tiny pieces of food that can hurt the fish．The fish gets a nice cleaning．The shrimp enjoys a tasty meal of fish trash．
Small birds called plovers（灰斑）are also in the cleaning business．They have big customers-crocodiles.Crocodiles have long noses filled with sharp teeth. Cleaning them is funny. When a crocodile opens its mouth, the plover hops right in．It lets the plover eat small, harmful animals attached to the crocodile's teeth．The plover gets an easy meal while the crocodile gets clean teeth．

On the first day of my new high school, I almost had a nervous breakdown. Everything about the school seemed so difficult. When I got home, my parents said, “You're nervous and that's okay. Everyone is afraid of high school.” I denied it. I wanted to be strong, so I refused to let anyone know about my fear, even my closest friends.
On the first day I was late for every class and was constantly lost. The school seemed like a puzzle that I couldn't figure out. Was this how the whole year was going to be? I didn't think I could rise to this challenge, especially carrying a huge backpack that I could hardly lift. It was so big that I could knock someone out with it!
Despite my fears, after the first week I finally had my schedule figured out. With the exception of falling up and down the stairs a couple of times and getting laughed at, high school was turning out to be not so bad. It was actually much better than middle school and much more challenging.Since then, I've been elected（选举）vice monitor of my class, which wasn't much of a victory since only three people ran for the four positions.
It is normal to be scared about a new school. Take a deep breath and relax. High school is something that any student can overcome. Make sure you participate in some out-of-class activities because you'll find it easier to make friends. Try to do your best, even if it isn't straight A's.
Most important of all, be who you are, whether you're a “fool”， an athlete, or a lower grader. Don't try to pretend to be someone you're not. Now you know the true secrets of high school.
