If our bodies actually suffer from eating too...

If our bodies actually suffer from eating too much sugar, then why do we like it? And why don 't we have such a strong eager for food like, say, broccoli (西兰花)，which is a great source of Vitamin C,Vitamin K iron, all things our body actually needs? If it's so bad for us, then why does sugar taste so good? There are hundreds of journal articles trying to answer that very question. Let' s take a look at what they' ve come up with.

Studies have shown that the love children have for sugar may be born with. In other words, kids may have a built-in love of all things sweet. The preference for sweet foods is found to be already evident in newborns, who prefer sweeter formulas (配方). It also seems to be shared by children globally across cultures and climates. There’s further evidence that kids’ taste buds (味蕾) are more sensitive to bitter-tasting foods, further pushing them to reach for the sweets. One study showed that adults tend to maximize their sugar preference at about the level of sugar in a can of soda, but older children still liked drinks that were twice as sweet. The scientists couldn't find a limit to the concentration of sugar younger children preferred. It turms out that the kids still liked the sugary drink even past the point where there was too much sugar to be dissolved (溶解) in water anymore.

Sugar gets a bad fame, but it isn't all bad. Sugar provides our bodies with calories, which we can then change into energy. Children, in particular, need this energy to fuel their rapid growth. Sugar also helps us store fat, which can be drawn on later if needed. Our body knows to pursue the things it needs as two way of signaling our brain to start eating what we’re missing.

As a vegetarian (素食主义者)，I know that when I start thinking about stealing the peanut butter sandwich that's been floating around in my kid' s backpack, it' s probably not because the sandwich is so delicious. It' s more likely that I haven't gotten enough protein for the day.

While the human world is suffering from the novel coronavirus outbreak, our planet is actually showing certain signs of “recovery” from the damage caused by human activity. According to the BBC, new satellite images released by the European Space Agency showed that levels of air pollutants and greenhouse gases have “fallen sharply” in major cities in Europe and the United States ever since the lockdown started.

This is what happened after recent discoveries in Antarctica. An international team of 89 scientists found that the ice in Greenland and Antarctica is melting six times faster in the 2010s than it was in the 1990s. And in February, Argentina’s Marambio research station in Antarctica recorded a record high temperature of 20.75 ℃ on the continent.

So what exactly will happen if the temperature keeps rising and the ice keeps melting? A third study might give you an idea. A team of scientists drilled a hole into the seafloor in west Antarctica and extracted (提取) material from underground, in which they found traces of roots, spores and pollen—typical products of a rainforest—that dated back 90 million years ago. In other words, Antarctica was very likely a rainforest back when the dinosaurs walked on Earth. But given the fact that the South Pole has four months of darkness during winter—even millions of years ago—scientists believe that the rainforest could only exist if the greenhouse gas concentrations were extremely high back then to keep the continent warm when there was little or no sunlight.

“We didn’t know that this Cretaceous (白垩纪的) greenhouse climate was that extreme,” Johann Klages of the Alfred Wegener Institute in Germany and a co-author of the research told the Guardian. “It shows us what carbon dioxide is able to do.”

Ice or no ice, Antarctica will be—and has always been—fine with extreme changes. The human world, however, may not be.

Now, during the coronavirus lockdown, we’ve seen the changes resulting from less human activity. Hopefully, we’ll hold on to those changes—not for Antarctica or the planet, but for ourselves.

1.What does Paragraph 1 mainly tell us?

A.Our planet is returning to its original state due to the novel coronavirus outbreak.

B.The lockdown of major cities contributed to the decrease of greenhouse gases.

C.The novel coronavirus has a positive effect on the human beings.

D.The novel coronavirus outbreak resulted from human activity.

2.What do we learn from the third study?

A.Typical products of a rainforest were dug out in Antarctica.

B.Traces of dinosaurs living in rainforests were spotted in Antarctica.

C.There was a good possibility of high greenhouse gas concentrations in Antarctica.

D.There used to be enough sunlight for the rainforest in the Cretaceous Antarctica.

3.Which of the following statements is true according to the passage?

A.Human activity doesn’t threaten life in Antarctica.

B.The ice in Antarctica is melting faster in the 2010s than now.

C.We should reduce carbon dioxide emissions for our own sake.

D.The lockdown can be carried on to slow down global warming.

4.What is the main purpose of the passage?

A.To encourage us to defeat the novel coronavirus.

B.To explain the effects of greenhouse gases.

C.To draw our attention to ecosystem in Antarctica.

D.To call on us to reduce human impact on the environment.

Everyone knows that eating too much junk food is not good to our health. Yet, what is it about junk food that is so completely irresistible(无可抗拒的)? For one thing, it’s everywhere. From chips in fast food restaurants to candy in supermarkets, junk food always seems available. Thankfully, science is now providing new clues to help us reduce snacking.

Make friends with dainty(讲究的) eaters.

Studies have found that people tend to increase or reduce the amount of food they eat depending on what their companions are taking in.

See happy movies… and always get the smaller bag of popcorn(爆米花).

According to some experts, people eat up to 29% more popcorn if they are watching a sad or serious movie, compared to when they are watching a comedy. Viewers consumed almost 200 calories more when snacking from a large bucket, as opposed to when given a medium-sized container.

Eat breakfast.

Nutritionists have gone back and forth（来来回回）about the question of how much to eat in the morning, but new studies suggest that consuming a good breakfast is a must. Surveys on long-term weight-loss show that two key factors in keeping weight down are eating breakfast and exercising.

Divide your food and conquer overeating.

Any kind of dividing your food into portions slows down your eating. Any kind of marker makes you aware of what you’re eating and of portion size. Researchers advise reallocating（再分配）snack foods into small plastic bags. It sounds simplistic, but it works.

1.Why do people eat too much junk food though it is bad for our health?

A. It’s delicious from chips to candy.

B. It’s easily taken everywhere.

B. Nutritionists have the same opinion about how much to eat in the morning.
