发霉的食物还能吃吗?

One day, you open the fridge and find some moldy food. But before you can throw it away, your mother stops you. She doesn't want to waste food. She cuts off the moldy part and eats the rest. Is it safe to do this?

Mold can grow on almost all kinds of food. Mold is usually green, white, black or grey. Mold makes food soft and changes its color. Moldy food tastes quite bad—and it's not safe to eat.

If you find mold in soft food, just throw it away. Soft food, such as bread, tomatoes or hot dogs, usually contains water. This allows mold to easily grow below its surface. Bacteria can also grow along with it.

But it's easy to remove mold from hard food. The mold can't grow very deeply inside this kind of food. According to the BBC, you should cut about 2.5 cm around and below the mold to remove it. It's OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, you should still throw it away.

Most kinds of mold are bad for us. But some kinds of mold can be used to make food. For example, penicillium can be used to make many types of cheeses, such as blue cheese. These cheeses are safe to eat—and they're quite delicious as well.

Do you want to be a very successful person? Being successful needs a lot, such as knowledge, hard work and maybe sometimes luck. Some experts(专家)share advice on how to become successful. Most experts agree on one thing：starting your day on the right foot is the most important.

Collected from the advice, here are some ideas on how to start your day off right:

Get up an hour early. People who get up early in the morning have a jump on the day. The morning may be the best part of your day when you can do your best work. "The early bird gets the worm." It means that people who get up early have a head start so they are more possible to succeed.

Drink a glass of lemon water. Why? Health experts say that drinking some lemon water first in the morning jump-starts the body's metabolism(新陈代谢). Not only does it jump-start your body's cells(细胞), but this kind of drink keeps them moving throughout the day.

Don' t answer email or jump into social media(社交媒体) as soon as you get up. During breakfast, you decide to check your email or open up your Wechat. You see some Wechat moments from friends. They post pictures to tell about something happy, sad, interesting or boring. Before you notice it, 10 minutes has passed! You hurry out of the door not to be late for school. This is not a good way to start your day.

Exercise! Running on the playground with friends may be a great way to start your day. Exercise experts often suggest some exercise in the morning because the middle of the day is busy for most people. By the day's end, you may feel too tired to exercise. How many times have you finished school and said to yourself, "I'm too tired to exercise! I'll do it tomorrow."

Think about your day at night, Take time at the end of the day to think back on all the things that you have done. You probably didn't have time to do everything you planned. But that's fine. If you did one thing, that means you are one step closer in reaching your goals(目标). And spend a little time thinking about tomorrow.

You will be successful as long as you start your day on the right foot.

1.Some experts think if we want to become successful, it is the most important to ________.

A.have some good luck B.work very hard at night

C.learn some knowledge D.begin our day in the right way

2.According to the passage, the writer believes that ________.

A.it's a great way to share moments on Wechat in the morning

B.drinking lemon water in the morning can help us fight colds

C.people who get up early in the morning are all very successful

D.it's good to do one thing that you plan a day and get close to your goals

No matter who you are, you need sleep. 1. While sleeping, the body recovers and rests. Throughout the day, we push our bodies to work as much as we need. At night, sleep allows our bodies to return to usual state. Our organs take turns resting, and our bodies fight off illness. In addition, our brains create dreams so that we can let go of mental stress. However, not everyone is able to sleep soundly.

2. They can be caused by physical problems. Some sleeping disorders are serious enough to interfere with normal body functioning. The most common one is snoring. In fact, everyone at some point in their lives snores.3. Therefore, when air passes through the smaller opening, it causes the throat to vibrate, which in turn leads to snoring. Snoring is not a serious problem, but it can disrupt the sleep of the snorers and their bed partners.

Other sleeping disorders that are often mentioned are sleep without breathing, sleep-loving and being sleepless.4. It occurs when the brain fails to tell the body to breathe or something gets in the way of the throat.

Sleep-loving is a nervous system disorder that causes extreme sleepiness during the day. As a result, the person can suddenly go from being fine to being very weak, dreaming while awake, or even falling asleep.5. Like snoring, it is very common, but seriously being sleepless may even stop a person from sleeping completely and it is always dangerous. Reasons for being sleepless can be different, but whatever the causes are, learning to relax helps people sleep better.

A.Sleeping disorders are common.

B.Trouble falling or staying asleep is called being sleepless.

C.It happens when the throat is not kept open enough while sleeping.

D.It is something that all animals and humans must get in order to be alive.

E.Sleep without breathing is when someone stops breathing while sleeping.

Bike­sharing has swept across China, with an increasing number of people choosing bike riding instead of driving. The bike that the service company provides has GPS or Bluetooth on it. And those bikes can be easily unlocked with a smart phone and left anywhere in public. Bike­sharing allows people to borrow a bike from one place and return it at another place easily.

In some cities, we can see more and more people riding this kind of sharing bikes. It's very convenient to use the bikes if you have a smart phone. First, you have to download such an APP on your smart phone. Then what you need to do is to find a nearest bike through the APP, scan the QR code(二维码)on the bike or connect your phone with the bike over a Bluetooth wireless connection. You will find the bike can be unlocked itself.

Then you can enjoy your trip. What's more, the greatest advantage of bike­sharing is that you can easily find one and never worry about where to park it. The cost of riding depends on the time that you spend. Normally, every hour you ride, you need to pay one yuan. It doesn't cost so much, does it?

At the same time, some people park the bikes in their own homes. Besides, some people don't value the bikes. Now service companies are trying to solve the problem like being stolen.

Technology and science have changed our social lifestyles. We have to say bike­sharing brings us more convenience without doubt. And we also hope that people can not only enjoy it but also put it to good use.
