1 . The next time you have cheese, remember the French scientist Louis Pasteur who discovered that bad milk, and many diseases are caused by bacteria(细菌).
Louis Pasteur is known as the father of microbiology. In his lifetime, he not only proved that bacteria are the cause of diseases, but also discovered the process of vaccination (接种疫苗) which has saved billions of lives.
When Pasteur worked with chickens that were suffering from cholera(霍乱) during his experiments, he accidentally spread cholera to his chickens. Pasteur’s chickens became mildly sick but did not die. This was strange as every chicken that came near cholera earlier had died. He realized soon that the cholera had become weak. By the time he tried again, the chickens he had cured earlier did not get cholera anymore. He realized that a weak cholera helped his chickens develop an antibody against it.
Later, Pasteur went on to try this on cows, pigs and dogs. All his research helped him develop different vaccines. We now know that the process of vaccination introduces a weakened kind of bacteria into our body. Our body reacts by creating antibodies to fight the bacteria. Now, when our body comes across the same bacteria which are much stronger, it can fight them off.
Louis Pasteur received numerous awards for the advancement of biology, chemistry, and medicine. He founded the Pasteur Institute to study diseases. It was the first university to teach microbiology and today there are 32 institutes across 29 countries. For every child vaccinated against a deadly disease, we have Louis Pasteur to thank.

5 . Most plants you see out in nature are leafy and green, at least for some part of their lives. That’s because they use green pigments, which are called chlorophyll (叶绿素), to harvest energy from sunlight. But the plant Hydnora Africana, doesn’t have leaves or chlorophyll at all.
So, how can it survive? Well, it’s a parasite (寄生), and H Africana attaches itself to other plants’ roots, and begins getting sugars, minerals, and water from its host.
At the same time, the parasite grows a root system, living completely underground, until it’s ready to reproduce. At which point, it grows one of the strangest looking flowers in the world. When the flower’s mature, it breaks the soil from beneath and reaches out in order to be pollinated (授粉).
But just as this plant doesn’t look like the normal flower, it doesn’t smell like one either. It gives out a smell like a rotting (腐烂) animal . The smell attracts insects and flies looking for a delicious meal. But when they get inside the flower and find no tasty treat, they can’t get back out again.
There’s a sort of room inside the flower, and the top of the room closes behind the insects. The walls of the flower are also slippery, making escape even more difficult.
Over the course of about a day, the flower’s male organs mature, and the insects get coated in pollen. And at the end of this transformation, the inside of the plant gets less slippery, and the chamber opens, allowing the insects and flies to escape.
At that point, attracted by a new rotting smell, they might just find another H Africana flower and pollinate it as they fall inside.

6 . Playing sports is a lot of fun. Getting hurt is not.
Wear protective equipment.
The equipment you wear depends on the sport you play. Helmets (头盔) are the most common protective equipment. They protect your head while you’re playing football, baseball, softball, and so on.
Warm up.
Know the rules of the games.
Traffic lights help prevent crashes between many cars that run on the road together. This works because drivers know the rules and follow them—at least most of the time.
This is a really important one. If you love sports, you may want to get back in the games, even after an injury. But playing when you’re hurt is a bad idea.
Now you know how to prevent sports injuries. If you follow these rules, you can stay safer while you are playing sports.

| B．Don’t do too much exercise. |
| C．It’s the same with sports. |

7 . Today was my first day at senior high and it was hard. In high school, we have 4 minutes to get to our next class. My high school is very big and those 4 minutes to go from one class to another really isn’t a lot of time. Today I had to go from one end of the building to the other to get from science class to math class. I wanted to go to my locker (储物柜) first and leave my science book there, but that took time. I was worried about being late, and I was. The math teacher said, “Just be on time tomorrow, or you’ll have detention(放学后留校).”
After math, I went to art class. I like my art class a lot because I get to create things. The teacher there showed us how to make portraits(肖像). He explained, “A portrait is a way of communicating with a person. It does not just show how the person looks but what is important to understand the person.” We just did drawings today, but I know it’s going to be great. I like drawing.
I like my English class, too. I think the teacher is really supportive. Today we wrote about ourselves. The teacher said that we just needed to write what we thought, and we would pay attention to punctuation(标点) later. We could write a paragraph or a poem, and I wrote a poem about myself. I thought it was a good poem, and the teacher said I had used good images (意象) to communicate my feelings.
Lunch was very hurried. I arrived at the dining room with 12 minutes to eat. I sat with people I didn’t know, and everyone was eating quickly. After lunch I signed up for a computer club. I needed to learn how to use a computer well because my social studies teacher said it is the one skill we need in every class.

8 . There are few things in the food world that bring about stronger opinions than spices like peppers (胡椒) and chilies (辣椒). Capsaicin (辣椒素) is the chemical in peppers that provides that burn you know and love.
Eating spicy food six or seven days a week — even just once a day — lowered death rates by 14 percent, according to a large 2015 study by Harvard and China National Center for Disease Control and Prevention.
“It seems to speed up the body’s fat-burning mechanisms,” says Patricia Bridget Lane, a registered dietitian/nutritionist. “That can help with weight loss and weight management.”
A 2012 review article published in the journal Chemical Senses mentioned that those who eat spicy foods like cayenne pepper noticed a reduction in their desire for fatty, sweet, and salty foods.
If you’re putting too much hot sauce in your food — or you’re eating entirely too many meals that are extremely-high in spice levels — you could be damaging your body as well.
According to one scientific study in the National Library of Medicine, capsaicin consumed in plenty can cause discomfort to the inner tissue of your stomach after you eat it. The resulting symptoms of too much capsaicin include “nausea”, “vomiting”, “abdominal pain”, and “burning diarrhea”.
Rebecca Tung, MD, a Florida-based dermatologist said, “When spicy food creates inflammation ( 炎症) in the gut — from an upset stomach, acid reflux, or other symptoms — sometimes this inflammation can also be seen on the skin with flushing, acne breakout, or even eczema.”
“Spicy foods can also kill sleep efforts because they cause heartburn. Lying down makes heartburn worse, and the discomfort from heartburn hinders sleep,” said the health experts at WebMD.
