Have you ever asked yourself why children go to school? You will     1     (probable) say that they go to learn languages, history, science and some other knowledge. That’s quite true, but do you know why they learn these     2     (thing)?

We send our children to school to prepare them    3     the future when they grow up and have to work for     4     (they). Nearly everything they study at school has some practical use in their life. But is that     5     only reason why they go to school?

Actually, there is more in education than just    6     (learn) facts. We go to school above all to learn how to learn, so that when we graduate we can continue to learn.     7     a man really knows how to learn, he will be     8     (success). Because when he has to do something new, he will not only be able     9     (do) it well himself, but he will also be able to teach others how to do it in the     10     (good) way. So the purpose of schools is not to teach languages, history, science, etc., but to teach students the way to learn.

Music is one of the most     1     (power) things in my life. Listening to music can help to motivate me in trying time. When younger, I     2     (have) no great love for music as I do now. I mainly listened to what my parents were listening to. Whether I was in the car, the house,     3     anywhere else there was sure to be some Beatles, or Buddy Holly constantly playing in the background. Now as I’m     4    (old), I enjoy it for the reason that it allows me to remember my childhood.

I believe music has the power     5     (express) all sorts of emotion. The song “A little bit longer” by Nick Jonas is     6     an emotional and inspiring song that when I hear it, I always come close to     7     (drop) down tears, especially when I watch it being played live. The effect     8     music can have on our emotions is great, as it can bring people to floods of tears or bursts of     9     (laugh).

I believe music affects people in many ways. To me, music is     10     (extreme) important in my life. I think it brings me closer to my friends and family.

Scientists often compare coral reefs to underwater rainforests, yet unlike the leafy plant base of a forest, corals are animals.The soft organs inside the hard parts of corals are naturally transparent and get    1    (they) famously brilliant color from algae(藻类）living inside them.

When corals experience stress from hot temperatures or     2     (pollute),they end their interdependent relationship with this algae,typically forcing them out     3    turning white, though one recent study indicates some corals turn a bright neon color when stressed.Corals are still alive when they bleach(白化），but they're     4     risk-essentially immunocompromised(免疫功能低下）－and many     5     (eventual) starve and die, turning a dark brown.

People first noticed coral bleaching events in the 1980s.The problem worsened in 2016, when an El Nino weather pattern,     6    causes warmer waters in the Pacific Ocean,     7    （mix) with an already unseasonably warm ocean and killed off a third of the corals on the Great Barrier Reef.Since then, roughly half the corals on Australia's famous reefs     8    （die) in following bleaching events, risking an underwater landscape 1,500 miles long.

Scientists around the world are looking for all kinds of ways to protect and maybe even revive corals.One option is     9     (create) more marine protected areas-essentially national parks in the ocean.Scientists say creating marine shelter, where fishing, mining,and recreating are off limits, makes the reefs     10     (healthy), and so much stronger.

Last week, our class was     1     duty in cafeteria for self-management. On the first day, I was shocked to see so much leftover food     2     (throw) away. What a waste! Concerned about it, my classmates and I had a     3     (heat) discussion on how to solve the problem. Lots of good ideas came up, such as holding class meetings, putting up wall newspapers and charging a fine for wasting food. Finally we all agreed that wall newspapers would be     4       (good) choice.

The next day, we put our idea into    5     (real). Towards lunch time, we put up     6     wall newspaper outside the school cafeteria,     7       (call) on students not to waste food. Many students gathered around to read and expressed their support. To my great delight, there were changes soon. In the cafeteria, I found the trays returned after lunch all empty     8     any leftover. Food       9    (save) and the dining hall was cleaner. Seeing this, I felt relieved and took pride in     10     we had done.

The fire at Notre-Dame Cathedral de Paris has raised questions about the condition of thousands of other cathedrals and historic     1     (structure) across Europe. It also raises questions about whether European government are doing enough     2     (keep) up and care for such buildings.

Tibor Navracsics, the European Union’s top cultural official, told The Associated Press that “we are so used to our outstanding cultural heritage in Europe that we tend to forget that it     3     (need) constant care and attention.” Some people say the fire was a wake-up call, not just for Europe,    4     for the whole world.

Large fires have long robbed humanity     5     knowledge, art and treasures. In 2015, the German engineering company Siemens     6     (find) that Scotland had about ten damaging fires a year, while England lost at least a dozen listed buildings a year. In Germany, seventy historic buildings have been     7     (heavy) damaged since 2000.

Experts say that     8     is needed is continuous attention and maintenance. Some say world-famous monuments like Notre-Dame are the     9     (drive) force behind tourism and should get more respect. Sneska Quaedvlieg-Mihailovic, who heads the heritage group Europa Nostra, noted the     10     (important) of such respect. “Cultural heritage is a gold mine. You cannot exploit it and then just leave the mine and go to another one.” She said.
