2 . Think about a world without insects. It might sound nice at first. There would be no annoying bugs or flies in your room. But in fact, this could be really bad news.
The number of insects has dropped a lot in recent years, according to British biologist Dave Goulson. “In the 27 years from 1989 to 2016, the number of insects fell by 75 percent, ” Goulson wrote.
Scientists say the main reason for this is the use of pesticides(农药). They destroy the places that insects live in. What would happen without insects? It’s almost impossible to predict, but the results would be far-reaching. We need insects to pollinate(授粉) crops. They also break down dead plants and animals and turn them into new useful things. We need them to keep the soil healthy and do much more. Without insects, many animals would have nothing to eat. They would go hungry and die. The ecosystem would be not balance.
The first step to stop this is to let more people understand “the values of the natural world, both for what it does for us and for its own sake, ” Goulson said. “The best place to start is with our children. We should encourage environmental awareness from an early age.”

5 . It’s been almost three years since COVID-19 began spreading around the world. There have been more than 400 million cases of the virus around the world. At least 6.15 million people have died.
After scientists developed vaccines（疫苗）that worked against the virus（病毒）, many countries began to pay attention to vaccination programs（疫苗接种）. The vaccines are great tools for fighting the virus.
One reason is that many poorer countries are struggling to get vaccines for their people. Our country has given away hundreds of millions of vaccines to those countries, but billions more are needed.
In some countries with strong vaccination programs, many people refuse to get vaccinated（接种疫苗）. Many of these people have gotten wrong information and may not be safe.
Finally, coronavirus “variants（冠状病毒变异）” are making it harder to beat（战胜）the virus. Now the “Delta variant and Omicron variant” seem to be the worst. They spread quickly and may cause more serious illnesses.
The two variants are causing terrible problems in countries where people haven’t had the chance to get vaccinated. Even in countries with plenty of vaccines, the variants are having a strong influence on unvaccinated people.
It’s clear that COVID-19 will be part of peopled life for quite a while. The best way to fight it seems to vaccinate as many people as possible.

Coconuts grow on trees. The word “coconut” comes from the old Spanish（西 班牙语）for “bogeyman（鬼怪）”. Early people from Spain thought coconuts looked like the terrible heads of bogeymen!
Coconut trees grow in hot countries, especially near beaches. Maybe you’ve seen them on your holidays! When it is picked from the tree, a coconut looks like a big green ball.

The coconut can be dried and added to other foods. It makes delicious ice cream, too. Even the milk inside the coconut is full of goodness. It has calcium（钙）, which makes your bones strong, and that would help you to climb the tree to reach the coconuts!
The coconut tree must be one of the most useful trees in the whole world! You can use almost every bit of it. It provides food, drink and also oil for cooking or skin care. The hairy covering is used to make ropes. The empty shells can be used as food bowls. The leaves can be used to make baskets, and the wood can be used as firewood. Now that is a really helpful tree!

9 . You might feel tired after solving a difficult math problem or studying for a whole day. Are our brains (大脑) really “burning (燃烧)” when we spend a lot of time thinking? In fact, our brains never stop burning calories (卡路里), even if we aren’t thinking about anything.
Our brain gets energy (能量) from a kind of sugar that is in rice and noodles. Our brain never really rests, it is burning energy in the form of sugar all the time. Even when we sleep, our brain needs energy to keep our body working. These include breathing, digesting (消化), and keeping the body warm.
The brain uses up 20 to 25 percent of the body’s total (全部的) energy. That’s 350 calories per day for a woman and 450 for a man. When you are five or six years old, your brain uses up to 60 percent of the body’s energy, according to Live Science.
When we are thinking hard, the brain burns more calories. In one study, researchers found that people who worked on a hard task on a computer ate around 200 more calories than those who were resting. That explains why you feel hungry and eat more after taking exams or studying for a long time.

10 . Do you get nervous thinking about coming math test? If yes, you are far from alone. Math anxiety has become a common psychological condition among students around the world. Students in countries with higher levels of math anxiety tend to achieve lower math grades, according to a study published in the National Academy of Sciences on Feb 15, 2022.
Math anxiety-a negative emotional reaction to the core subject causes fear, physical suffering and behavior problems among young pupils, according to a University of Cambridge study. In ordinary life, many people experience some degree of discomfort when faced with a math problem, ranging from mild stress to strong fear.
Some people also experience physical changes such as having sweaty (出汗的) hands or a racing heart. They may then try to avoid every situation including number, meaning they are held back from working in the fields related to this subject, such as science, technology or engineering, according to The Guardian.
Reassurance (慰藉) comes from the fact that those with math anxiety aren’t born to be bad at math. “If a child has math anxiety, don’t think that they’re not good at math. They may have had a really bad experience with math and there are ways to improve math achievement,” Daniel Ansari, the senior author of the study told The London Free Press. Students with math anxiety are not cognitively (认知地) disadvantaged.
Also, there are ways to manage your stress related to math. If you’re feeling stressed before a math exam, it may help to spend a few minutes exploring those feelings before the exam begins. It’s about making sure you understand your feelings correctly. Just because you have a fast heartbeat and sweaty palms, that does not necessarily mean you will fail.
A little math anxiety could be taken as a positive challenge to overcome. Just like many people get stage fright before delivering a speech, this nervous energy can help to motivate.
