【推荐1】A new study shows that rising levels of planet-warming gases may reduce important nutrients in food crops.

Researchers studied the effects of one such gas—carbon dioxide—on rice. The researchers grew rice plants in a controlled environment. They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century. They found that the resulting rice crops had lower than normal levels of vitamins, minerals and protein. The researchers said the effects of planet-warming gases would be most severe for the poorest citizens in some of the least developed countries. These people generally eat the most rice and have the least complex diets, they noted.

In the experiment, scientists grew 18 kinds of rice in fields in China and Japan. They pumped carbon dioxide gas over the plants in an effort to create the atmosphere of the future. Rice grown under high carbon dioxide conditions had, on average, 13 to 30 percent lower levels of four B vitamins and 10 percent less protein. The crops also had 8 percent less iron and 5 percent less zinc（锌）an rice grown under normal conditions. However, vitamin E levels increased by about 13 percent on average.

The results are bad news, “especially for the nutrition of the poorer population in less-developed countries,” said the University of Tokyo’s Kazuhiko Kobayashi, who helped to write the report. That includes about 600 million people in Indonesia, Cambodia, Myanmar, Bangladesh, Laos and other nations, mainly in Southeast Asia, the report said.

One of the scientists is Sam Myers of Harvard University in the American state of Massachusetts. He said that findings like this are an example of the surprises climate change create. “My concern is there are many more surprises to come,” he said.

Myers noted that pollution, loss of some species, destruction of forests, and other human activities are likely to produce unexpected problems. He said that you cannot completely change all the natural systems that living organisms have grown to depend on over millions of years without having effects come back to affect our own health.

The new study suggests a way to lower the nutritional harm of climate change. One way, Kobayashi said, is grow different forms of rice that have shown to be more resistant to higher carbon dioxide levels.

Working women make up nearly half of the U.S. workforce, and 51 percent of professional workers, like doctors, lawyers, nurses and accountants, are female. While climbing the career ladder can be rewarding, it often comes with one big disadvantage: weight gain!

New research published this week in the International Journal of Obesity shows that working women are more likely to be overweight, and the more you work, the more pounds you’re likely to pile on. Like many women, I work... a lot! As a self-employed nutrition communications specialist, I sit at my desk, in front of a computer, for hours on end. Sitting alone is one of the worst things you can do for your health, and it’s directly linked to being overweight and increased fatness, so the fact that women in the workforce gain weight isn’t that surprising. If you work, you have less time to move around. Obesity researchers are revealing many other ways that employment is harmful to your diet and waistline(腰围).

In the International Journal of Obesity study, some 9,276 Australian women aged 45-50 had their body weight and employment status monitored for two years. Results? Those who worked more than 35 hours were likely to gain weight compared to those who worked fewer hours or were out of the workforce. What’s more, the more hours a woman worked in a week, the more weight she gained.

The authors of the Australian study attribute weight gain among working women to inactivity, lack of time for food preparation, more use of prepared foods, high levels of stress, lack of sleep and consuming more alcohol. I’ll also add in travel, meals eaten out and working at night as other factors that I can find to make balancing work with a healthy diet a challenge.

1. A female lawyer is more likely to ______.

C．Having little time to prepare for food.

D．Drinking too much alcohol.

3. The passage above is probably taken from ______.

A．a fashion journal	B．a sports report
C．a health and fitness magazine	D．an advertisement post

4. What can be a suitable title for the test?

A．How to lose weight for working women.

B．Women should take more exercises.

D．Working women more likely pile on pounds.

【推荐3】We’ve all heard that breakfast is the most important meal of the day, and that may actually be true. A study of more than 50,000 adults aged 30 and older found that breakfast eaters were more likely to lose weight than those who didn’t eat a morning meal. To have a satisfying and nutritious breakfast, these tips will help you really rise and shine:

Eat even if you’re not hungry.

Although you might not feel like eating first thing in the morning, it’s a good idea to get something into your system. Eating within 90 minutes of waking up will jump- start your body and keep you from getting hungry later.     1    

Go boring.

Varying what you eat is a good idea in theory.     2    A 2014 British study found that people who allowed their breakfast calories to rise and fall (as measured by a five-day diet diary) had larger waists than folks who kept their morning calorie intake constant, no matter how much they ate the rest of the day.

Go big.

There’s an old saying that advises “Eat breakfast like a king, lunch like a prince, and dinner like a beggar.” It’s worth following. According to a study of 93 overweight women, those who ate a balanced 700-calorie breakfast over a 12-week period lowered their blood sugar and blood pressure two times more than people who ate a 200-calorie meal.     3    

Always pick a protein.

A review of recent studies in the health journal Advances in Nutrition found the function of protein.     4    Shapiro recommends eggs, nut butter, or cheese (which is generally a little lower in sugar than yogurt) to give your breakfast a protein boost.

Embrace fat.

Actually, fat isn’t the main enemy to weight loss success—sugar is. Fat is digested slowly by the body and helps decrease the rate at which we digest and break down carbohydrates (碳水化合物).     5    So you need some fat (at least 1 to 2 percent) to help your body absorb those nutrients more efficiently.

A．It can also dissolve and break down vitamins A and D.

B．Just a banana will do the trick.

C．A variety of foods are mouth-watering and full of nutrition.

D．The breakfast needs to be high in protein.

E．But you’d better stick with the same old menu for your weight.

F．They also lost an average of 19.2 pounds.

G．High level of it in breakfast can reduce hunger later in the day.

Is it better for our bodies to work out at certain times of the day? Scientists have known for some time that every tissue in our bodies contains a kind of biological clock that goes off in response to messages related to our daily exposure to light, food and sleep.

However, whether and how exercise timing might influence metabolic（新陈代谢的）health has been less clear, and the results of past experiments have not always agreed. A much-discussed 2019 study found that men with Type 2 diabetes（糖尿病）who completed a few minutes of high-intensity interval（间隔）sessions in the afternoon improved their blood-sugar control after two weeks. Patrick Schrauwen, a professor of nutrition and movement sciences read that 2019 study with interest. He had been studying exercise in people with Type 2 diabetes, but had not considered the possible role of timing. Now, seeing the varying impacts of the intense workouts, he wondered if the timing of workouts might similarly affect people’s metabolisms.

Incidentally, he and his colleagues had a ready-made source of data in their own prior experiment. Several years earlier, they had asked adult men at high risk for Type 2 diabetes to ride stationary bicycles at the lab three times a week for 12 weeks, while the researchers tracked their metabolic health. They also had noted when the riders showed up for their workouts. The researchers pulled data for the 12 men who consistently had worked out between 8 and 10 a.m. and compared them with another 20 who always exercised between 3 and 6 p.m. They found that the benefits of afternoon workouts far outweighed those of morning exercise.

He says, “This study does suggest that afternoon exercise may be more beneficial for people with disturbed metabolisms than the same exercise done earlier. The particular and most effective exercise for each of us will line up with our daily routines and exercise tendencies because exercise is good for us at any time of day — but only if we choose to keep doing it.”
