China Mobile says 5G networks do not _______ (要求) new SIM cards. It's really good news for customers.
(2018·山东临沂)What was discovered by accident? The answer is penicillin (青霉素). It kills germs. By killing germs, it saves lives. Suppose you are sick. You go to a doctor. She examines you. She says you have a “staph” infection (葡萄球菌感染). She gives you some medicine. You take it. The medicine knocks out the staph. Soon you are well. Before penicillin, this would not happen. Staph was almost sure death.
Everyone wanted a medicine. Laboratories worked day and night. They grew the staph in small dishes. Then they tried to kill it. Nothing worked.
The laboratory dishes had covers on them. They kept things from falling into dishes. Molds (霉菌) were a big worry. They are always in the air. You can’t see them. They’re too small. There are thousands of different molds. Molds can make an experiment (实验) fail. That’s why dishes are covered.
Dr. Alexander Fleming was working to kill the staph germ. He worked for years. One day he took a cover off a dish. He looked inside. There was a thick growth of staph germ. There was also some mold. Then he saw something strange. Where the mold was, there was no growth of staph. This is what Fleming probably thought. “By accident, I found a mold to kill the dreaded staph.”
This is how penicillin was found. But here’s the real miracle (奇迹). There are thousands of kinds of molds. But only one kind can kill staph. The mold must have fallen into the dish a few days before. The cover was probably off only a few seconds (秒). In those few seconds the right mold fell into the right dish. Another man might have thrown the dish away. But Fleming was very careful and smart. He understood what the mold did. How lucky the humans were!

Today we had PE, so the first thing I did when I got outside was sneak off (偷偷摸摸) to the basketball court to see if the Cheese was still there. And sure enough, it was.

After a couple of days, the Cheese started getting all moldy (发霉的) and nasty.

Has such a scene ever come to your mind? You’re sitting in the hot sunshine beside the swimming pool of your international hotel, drinking your expensive whisky. In front of you is the beach, only for hotel guests. Around the hotel are fancy international restaurants.
Is this your idea of paradise (天堂) or would you prefer something different?
Nowadays, many of us try to live in a way that will harm the environment as little as possible. We recycle our newspapers and bottles, we take public transport to get to work. And we want to take these attitudes on holiday with us. This is why ecotourism(生态旅游) is becoming more popular all over the world.
Everyone has a different idea about ecotourism, but most people agree that ecotourism must: protect the wildlife and culture of the area; do no harm to the nature; offer an experience that tourists want to pay for.
So, for example, in a true ecotourism project, tourists stay in local(当地的) houses with local people, not in specially built hotels. They travel on foot, by boat, or bicycle so that there is no pollution. And they have a special experience that they will remember for the rest of their lives.
This type of tourism can only involve(涉及)a small number of people, so it can be expensive. And if you want to have an “eco” holiday wherever you go, remember these basic rules:
• Be prepared. Learn about the place that you’re going to visit. Find out about its culture and history. Think of your holiday as a chance to learn something.
• Have respect for the local culture. Wear clothes that will not annoy people. Always ask permission before you take a photograph. Remember that you are a visitor.
• Don’t waste resources. If the area doesn’t have much water, don’t take two showers every day.
• Stay in local hotels and eat in local restaurants.
But before you get too excited, think about how you are going to get to your dream “eco” paradise. Flying often causes air pollution. So don’t forget that you don’t have to fly to foreign places for your “eco” holiday. There are probably places of natural beauty in your own country that you’ve never visited.
1.The passage is led in through ______.
A.an introduction B.imagination C.a story D.advice
2.If you want to have an “eco” holiday, you are supposed to do the following EXCEPT ______.
A.taking photos when you are allowed to B.saving resources
C.wearing whatever you like D.learning about the place you’re going to visit
3.We can infer from the passage that ______.
A.eco-tourism may be welcomed by the local people
B.international restaurants and hotels have a lot to do with ecotourism
C.choosing holiday places that don’t need air travel can be a part of ecotourism
D.people can only travel to places in their own country to have an “eco” holiday
4.The best title for the passage may be ______.
A.How to Choose Holiday Places B.The Advantages of Tourism
C.How to Protect the Environment D.Ecotourism—A Different Way of Taking a Holiday
It can be difficult to remember things in the long term, because memories may get lost over time. But you can change the way you learn new information in order to successfully remember it in the long term.
Focus on (专注于)new information. It’ll be easier to remember something in the future if you give it all of your attention while you’re trying to learn it. Don’t try to do several tasks at the same time. While you are learning, turn off the TV and put your phone somewhere you can’t see it. It helps new information move from your short-term to your long-term memory. And you may need to ask your roommate or family to give you some quiet time.
Take a break after learning something new. Just sit quietly for a few minutes. Avoid trying to get other things done during this time, as it will interfere with ( 干扰 ) the process of building the new memories you’ve just formed.
Review information right before bed. Studies suggest that your brain uses sleeping hours to review and choose what you will be able to recall in the long term. For this reason, you can improve your long-term memory by going over information that you want to remember right before you go to sleep.
Organize information into related groups. For example, if you’re trying to remember a shopping list, group the things into categories (种类) like “vegetables” and “fruits”. Then try to memorize each category separately.
