My mother and I were riding a bus in a Saturday morning near my school. I told her how much her English teacher Miss Smith loved me, saying that I was the teacher’s a favorite student. I didn’t know that Miss Smith’s mother is riding behind us. She heard everything. On Monday, Miss Smith kept me after class. To my shames, she told me that her mother had heard. I thought she would scold me for talk too proudly on the bus. So she didn’t. She said，“The important thing is that you work yourself，not for my approval. If you feel that doing well matter to you，you become your own fan.”

Have you ever had someone tell you, “If you eat before bed, you're going to get fat” 1. But is eating late at night, specifically after 8 p.m., really going to make you gain weight?
One theory is that your metabolism(新陈代谢)slows down when you're asleep. With a slower metabolism, fewer calories are being burned. Thus the calories you eat right before bed would not be bumped off as much as they would be while you're awake. Although the science seems pretty sound, recent studies have shown that metabolism changes very little while you are asleep. The heart is still beating, lungs are still working, and the brain is still very active. 2. So while we are asleep, we are still burning calories.
3. Carbohydrates(碳水化合物)are one of your body's main sources of energy. When they go unused, they are stored primarily as fat. However, the time of day that carbohydrates are consumed does not play a role as to how much of it is stored as fat.
Actually, weight gain is based on the amount of calories being consumed overall and the amount of calories used overall. 4. It has little to do with the time when you eat. So how come individuals have higher BMIs when they snack' at night? Although there is a relation between the two, it is simply a result of eating too many calories!
Snacks that individuals tend to eat during the night are usually high in sugar and calories, such as ice cream, candy, potato chips, and soft drinks. The time these snacks are consumed does not matter.5..
A.All of these actions take energy.
B.That is to say, you will not get fat if you eat before bed.
C.Anyone eating anytime after the morning will become fat.
D.Food consumed late at night will more likely be stored away.
E.Without ever questioning it, people quickly assume this to be true.
F.Simply speaking, if you eat more calories than you burn, you will gain weight.
G.There's another theory about eating specifically carbohydrates before bed.
If the lady in the Mona Lisa painting could talk, she could tell us why she was smiling for the pose, isn’t it? But, of course, that is not possible because she is just a painting.
However, recently, Samsung Labs in Moscow demonstrated an Al program that could create a video of a person talking just from one single profile picture. The result? A talking Mona Lisa, thanks to a technology, known as deepfake!
The word “deepfake” is a combination of the words “deep learning” and “fake”. Deep learning refers to the use of machine learning and artificial intelligence to create images of human faces. The word was used first in 2017 when an anonymous person using the name “deepfake” began to post images of celebrities’ faces on other people’s bodies.
To start with, video recordings of a person are broken down into the smallest levels of detail that capture how their mouth and facial features move when they pronounce a sound like “oo” or “ah”. These, along with the 3-D model of the lower face, are then put together and the person can be made to say words he (or she) never did.
Deepfakes use a technology called generative adversarial networks (GAN). This system uses two separate artificial intelligence systems that are trained such that one generates the images and the other attempts to tell if they are fake. The machines continue to teach each other over and over again until one produces a video that the other cannot tell it is fake!
Fake news would easily go out of hand if people believed the fake videos as real and it could have political and social effect. There is a lesson here for each of us to be careful about what we post on the Internet. In the future, you might see a picture or video of yourself and may not be able to tell that it is fake! It all just goes to show that seeing is not always believing.

A.People can use deepfakes to become famous.
B.The public aren’t easily cheated by deepfakes.
C.All of us may become a victim of deepfakes.
D.Deepfakes make what you have done known to all.
4.What is the best title for the text?

Sometimes fishing ships disappear: Captains turn off the radios that broadcast their locations, leaving regulators wondering whether the ships are fishing illegally. Now, researchers have shown that albatrosses(信天翁)bearing small detectors can find these doubtful ships, even in the middle of the open ocean. After a 6-month study with the large seabirds, the researchers say that more than one-third of ships in the southern Indian Ocean are fishing illegally.
“These are animal police,” says Boris Worm of Dalhousie University. “You’re empowering animals to survey their own environment, ”Worm says. “That’s pretty cool.” The method could also help albatrosses themselves, which can be killed when they get caught or accidentally eat fishing hooks. The researchers will be there on time.
Illegal fishing is a major concern for environment biologists, especially in remote areas. Over the past decade, scientists have studied the problem with data from automatic identification systems (AISs) on ships, which send their identity, location, speed, and direction to satellites. But AlSs can be turned off. Researchers suspect that fishing ships turn off AISs when they are fishing illegally or want to prevent competitors from knowing where they are getting a good catch.
Albatrosses make good spies. The birds, which live on fish, can spot a fishing ship from as far away as 30 kilometers. Some species fly hundreds or thousands of kilometers while hunting. Between December 2018 and June 2019, the birds met 353 ships. Those locations were sent to the lab in less than 2 hours. If they did not match the locations of ships with an active AIS, the team knew the ships had switched it off. In international waters, 37% of detected ships had their AlS switched off and fished illegally.
Although the albatrosses can detect ships, they cannot track them over longer distances, one scientist says. He says, “What you need to do is to look for patterns to take pictures as evidence.” More albatrosses will be arranged in March and April around the Prince Edward Islands in the southern Indian Ocean to reveal the illegal fishing.
1.What is the main idea of the first paragraph?
A.Fishing ships disappear sometimes.
B.Illegal fishing is very serious in the open ocean.
C.Some seabirds are used to monitor the illegal fishing.
D.One-third of ships in the southern Indian Ocean are fishing illegally.
2.What benefit will the method do for the albatrosses?
A.They can get enough food.
B.They can get saved when in danger.
C.They can protect their own rights of fishing.
D.They can avoid being killed or eating fishing hooks.
3.How do the seabirds offer help?
A.By sending locations of ships.
B.By turning off AISs of the ships.
C.By following the ships as far as possible.
D.By taking the pictures of ships fishing illegally.
4.In which column of a newspaper can this text be read?
A.Education. B.Politics. C.Science. D.Health
