“Zero calories (卡路里) and getting no weight.” We often talk about sugar-free drinks like this. But are they really a good choice?
Some people think sugar-free drinks are healthier because they don’t have sugar or calories. They think having these drinks can help them lose weight.
In fact, sugar-free drinks have some sugar, although very little. Usually, if there is 0.5 grams (克) of sugar or less in a 100-gram drink, it can be described as a sugar-free drink. Although they have little sugar, sugar-free drinks still taste sweet because they use artificial sweeteners (人工甜味剂). But they have very few calories.
When we eat sweet-tasting things like sugar, they hit our brain and make us want more. Our brain tells our body to prepare itself for more sugar. When we drink a sugar-free drink, the brain receives the “sweet message”, but no sugar arrives. Since the brain is fooled, it still wants more sweets.
Some people drink sugar-free drinks instead of water. This is not a good choice. Sugar-free drinks can be bad for our teeth and influence our appetite (食欲).

【推荐1】Many cars in advertisements and car exhibits（展览）in the United States are red,blue or green-- but almost 75 percent of new cars sold in the United States are black, white, silver or gray.
Les Jackson is a reporter who writes about cars. He says the car colors Americans choose do not show dirt as much as the colors of other cars.
Dan Benton works5 for a company called Axalta, which makes supplies for international car makers. He says when white cars are sold by their owners, they often sell for higher prices than cars of other colors. And he notes that white cars “take up less energy” than cars of other colors. This means temperatures inside them are lower in warmer areas.
Benton also says that there is a lower risk of crashes during the day for white cars compared with darker ones.
Axalta says about 11 percent of cars sold in North America are red and 8 percent are blue. In South America, 10 percent of new cars sold are red.Green has become less popular. Benton notes that in the mid 1990s, “green was the most popular color in North America. Today, green is hard to find.”Sometime in the future, people may not have to choose the color of their car -- technology may let owners change their car’s paint color anytime.

Replacing Real Meat
Do you know plant-based meat(植物肉)? A few years ago, one of my friends asked me to try a burger. It tasted a little different from a “real” burger, but it wasn’t bad either.
Plant-based meat is meat made out of plant protein(植物蛋白). For example, wheat and peas(豌豆) can be used to make it. But plant-based meat looks and tastes just like real meat. It’s becoming more popular around the world these days.
Experts say this food is good for physical health. If people eat too much meat, it will lead to many illnesses such as heart problems.
Environmental protection is another reason for people to choose plant-based meat. Most greenhouse gases (温室气体) in the world comes from the meat industry. If everyone stops eating meat, it will cut down greenhouse gas emissions(排放) by two-thirds.
However, some people still like to eat real meat more than plant-based meat. They wonder if plant-based meat is safe or healthy. Higher prices also hold some people back. For example, Burger King’s plant-based burger is one dollar more expensive than a real meat burger.

【推荐3】It’s hard to believe that a beautiful silk dress comes from thousands of very little worms (蠕虫) called silkworms! It takes about 5,500 silkworms to make 2.2 pounds of silk. The process was invented by the Chinese about 5,000 years ago.
How is silk made? The process starts with silkworm eggs. The eggs are collected and kept warm. After a few days, silkworms come out of the eggs. They are fed leaves from mulberry trees (桑树) every 30 minutes, all night and all day. The room must be kept warm, without loud noises or bad smells. After a month, they start to make cocoons (茧). After four days, the cocoons are over.
The cocoons are heated (加热), and the silkworms are killed inside them. Then the cocoons are put into water to make the silk loose (松散的). The silk from three or four cocoons is put together and made into a thread (线). One cocoon can make a thread 1 kilometer long! Finally, the silk threads are made into cloth, and the cloth is used for things like dresses, scarves and neckties (领带).
Today, silk is produced in many countries, including India and Thailand, but more than 80 percent of the world’s silk comes from China. Every year, enough silk thread is produced to go from the earth to the sun 300 times. People love silk clothes because they are beautiful and comfortable—silk feels cool in warm weather and warm in cool weather. Now you know why silk is so expensive!

We are often told to pay attention to what our mothers tell us. Scientists have found that our brains greatly prefer the voices of our own mothers.
Scientists at Stanford University recently studied this. They scanned (扫描) children’s brains while they were listening to different sounds, including their mothers’ voices. They found that 97 percent of the time, children could recognize (识别) their mothers’ voices at once.
Hearing their mothers’ voices makes children’s brains more active. We usually just use one part of our brains to deal with sounds when we hear something. But when we hear our mothers’ voices, many parts of the brain start to work as well.
Why do we reply so strongly to our mothers’ voices? On one hand, when we are still in the womb (子宫) before we’re born, we hear our mothers talking. This makes us feel comfortable. On the other hand, mothers teach us talk and social skills by repeating words again and again. This way, when mother’s sound is heard again, more attention is paid to it.
Some sounds are necessary for our life and they bring us pleasure. But mothers’ voices are different and they make us feel comfortable. We will feel very relaxed when we hear our own mothers’ voices.
