On February 6, 2020, American astronaut Christina Koch arrived back on Earth after 328 days in space. Her time in space is just one of the records set by herself. That’s the longest spaceflight ever made by a woman, and just one of the many things Ms. Koch achieved in space.
Ms. Koch took off from Earth for the International Space Station (ISS) on March 12, 2019. While in space, she made 5, 248 trips around the Earth, travelling 2, 237 million kilometers, which is roughly the same as 291 trips to the Moon and back. During her 11 months on the ISS, Ms. Koch took part in six spacewalks, spending over 42 hours in all outside the station. In October of 2019, Ms. Koch led the first ever all-female spacewalk with Jessica Meir.
But for most astronauts, space travel isn’t about setting records. It’s about doing science. Ms. Koch took part in a wide variety of special experiments, including studying how crystals (晶体) grow in space, how atoms (原子) behave in extreme cold and learning more about growing plants in low gravity. Growing plants in space could be an important way to provide food on future trips. She also tested a new way of separating liquids from gases. This experiment could lead to simple methods of cleaning water and air in space, which could be very important for future space travel.
Ms. Koch isn’t just a scientist and an astronaut. She is also being studied. She’s part of a NASA program studying how astronauts are affected by being in space for long periods of time. Her trip was only 12 days shorter than the American record set by Scott Kelly in 2016. As they did with Mr. Kelly, NASA scientists are looking carefully at ways Ms. Koch’s body has been affected by her time in space. That research is important for the longer space trips NASA hopes to make in the future, such as for a base on the moon or a trip to Mars.

Unhealthy diets are responsible for preventable deaths globally per year, more even than smoking tobacco, according to a major study.
“But the biggest problem is not the junk we eat but the nutritious food we don’t eat,” say researchers, calling for a global shift in policy to promote vegetables, fruit, nuts and beans. While sugar and trans-fats are harmful, more deaths are caused by the absence of healthy foods in our diet. Heart attacks are the main diet-related causes of death, followed by cancers and diabetes (糖尿病).
The study found that eating and drinking better could prevent one in five deaths around the world. “Rather than trying to persuade people to cut down on sugar, salt and fat, which has been the main focus of diet policy debate in the past two decades, it would be better to promote healthy options. Adoption of diets emphasizing beans and other healthy plant sources of protein, for instance, will have important benefits for human health,” note the researchers.
The study is the most comprehensive analysis on the health effects of diet ever conducted. It looked at 15 different nutrients, giving detailed knowledge of the analysis and summary of the risk factors of them.
Tom Sanders, a professor of nutrition and dietetics (饮食学), said the analysis put too much emphasis on individual components rather than the overall diet. “Overweight is a major driver for risk of diabetes as well as cancer and the health evidence for this relationship is strong. Overweight is caused by eating more food energy than required rather than specific dietary components such as sugar. The trend for populations to sit too much is a major reason why there is an imbalance between energy intake and consumption but Increased availability of foods with high calories makes it too easy to overeat.”
1.What do the researchers think is the best way to lower preventable death rate?
A.Restricting junk food. B.Trying to eat healthily.
C.Avoiding risk factors. D.Adopting high-calorie diets.
2.What’s the major concern of the current diet policy?
A.The diversity of food.
B.The importance of nutritious food.
C.The reduction of unhealthy food intake.
D.The balance between diet and exercise.
3.Which of the following does Tom Sanders agree with?
A.The analysis overlooks dietary integrity.
B.Overweight results from diabetes and cancer.
C.People who rarely exercise must diet strictly.
D.Particular dietary components lead to overweight.
4.Where is the text most likely from?
A.A product brochure. B.A cookbook.
C.A medical textbook. D.A health journal.
Bahamas’ 4 Best Budget Beachfront Hotels
Hundreds of islands and beaches in Bahamas have long been attractions for travelers. Here are 4 unique beach destinations.
Pigeon Cay Beach Club
Pigeon Cay Beach Club is located on the largely undeveloped Cat Island, where it’s possible to wander the coastline for miles without spotting a soul. TVs, AC, and Wi-Fi are all off-duty, leaving guests to explore the island by bike and boat. Meals can be served at the beach bar, on the beach, or in the cottages, which all have full kitchens and furnished outdoor spaces.
Compass Point Beach Resort
Compass Point Beach Resort may be Bahamas’ most interesting property. The resort was opened in 1995 by a music producer. Its appearance is as noticeable as its history. It’s composed of 18 rainbow-colored small wooden houses. All rooms have surround-sound music systems, open-air kitchens and dining spaces.
Stella Maris Resort Club
If you’re looking for a casual, cheerful, and cheap life, the beachfront Stella Maris Resort Club more than fits the bill. The large, family-owned complex is a bargain for its competitive rates and accommodations that suit larger parties. One of the highlights of the resort is its range of activities, many of which are free, including day trips, boating, nature walks and caving.
St Francis Resort
If you want to go off the Internet, St Francis Resort is as remote as you can get. The resort is only accessible by boat and has little human development: no cars, no roads, and only about two dozen residents. But it’s not all peace and quiet: the restaurant draws plenty of boaters and day-travelers and the hotel hosts activities like poker nights and weekly barbecues.
