    1    Bacteria can spread throughout the kitchen and get onto cutting boards, knives, and counter tops. To avoid the risk of foodborne illnesses, people should pay special attention to the handling and preparation of foods.

Keep foods apart. Bacteria can spread from one food product to another. This is especially true for raw meat and seafood.     2    

Put foods in a refrigerator without delay. Public health officials advise consumers to refrigerate foods quickly.     3    Refrigerators should be set at 40 degrees F and the freezer at 0 degrees F, and the accuracy of the settings should be checked now and then.

Keep foods at a safe temperature during thawing(解冻). Let’s take turkey for example. Thawing the turkey completely before cooking is important and necessary to reduce the risk of foodborne illnesses.     4    For example, a 20-pound turkey needs two to three days to thaw completely when thawed in the refrigerator at a temperature of no more than 40 degrees F.

    5    Foods are properly cooked when they are heated for a long enough time and at a high enough temperature to kill the harmful bacteria that cause foodborne illnesses.

But until now, few studies have actually investigated (调查) why. This is what a recent US study set out to uncover.

Researchers had 16 participants follow two different meal schedules, each for a period of six days in total. The first group had their meals early in the day with the last meal consumed six hours and 40 minutes before bedtime. The second group had their daily meals four hours later. This meant they skipped breakfast and instead had lunch, dinner and an evening meal. Their last meal was consumed only two and a half hours before sleep. All the participants consumed the same diet, and all of their meals were equally space d with around four hours between them.

The researchers looked at three measures associated with weight gain: the influence of appetite, the impact of eating time on calories burned, and changes of fat tissue (组织). They found that compared to an early eating pattern, late eating not only increased feelings of hunger the following day, it also increased the rate of “hunger” hormones (激素) in the blood. Late eating also caused a decrease in calories burned the following day. Fat tissue samples taken from the participants also showed the increased fat storage. These results suggest that late eating could lead to weight gain.

Given that the study was only conducted on a limited number of participants and over a very short time, more research will be needed to further understand whether these changes are only temporary, and what effects long-term late night eating can have on the weight gain mechanisms (机制).

Anyway, this study adds to a growing body of evidence showing just how important meal timing can be when it comes to body weight. Therefore, people who are watching their weight may want to stay away from the late night snacks and favour eating most of their meals earlier.

【推荐1】They say that Mexico is a country no one ever leaves. Every year, millions of tourists pass through, and Mexicans jovially (高兴地) warn that a part of them will remain behind forever. Most visitors are vacationing North Americans who wind up on the brilliant beaches of Cancun, Acapulco, Mazatlan, and Puerto Vallarta. The beaches, of course, are among the world’s best—but those who venture inland are rewarded with the true soul of Mexico, which has always resided firmly in the interior.

And it is a big soul. Mexico is vast, made up of nearly two million square miles of coastline, desert, rain forests, mountains, and fertile plains. From the American borderlands of the wide, agriculturally rich north, the country narrows gently as it sweeps south and east. The two main mountain ranges, the Sierra Madre Occidental and the Sierra Madre Oriental, hug the west and east, finally merging (并入) into the volcanically active central highlands and the capital, Mexico City—the most populous city in the world. Further south, the country narrows to only 100 miles, then broadens again before reaching the Guatemalan border. There are two major peninsulas (半岛) that are almost countries themselves. In the west is the poetically barren Baja Peninsula; to the east, protruding into the Caribbean like the end of a fish hook, is the Yucatan peninsula, bursting with rain forests, Mayan ruins, and white powder beaches.

The population is about 106 million, and the generosity（慷慨大方）of the Mexican people is unsurpassed (非常卓越的). Knowing a few simple sentences in Spanish will win hearts.

Mexico has been graced with an unusually temperate climate year round. The most important thing to remember is that the Mexican summer is also the rainy season, although the rain rarely lasts more than a few hours, and typically arrives in the late afternoon. Extremes are present only in the North and in Baja, both of which have deserts where the temperature leaps above 100F. Mexico City has a year-round temperature in the high 80s, while the coasts usually stay in the mid-90s. Night time temperatures fall somewhat, but rarely break down below a comfortable 60F.

【推荐3】The world’s animal populations have decreased by more than two-thirds since 1970, according to a recent research from the World Wildlife Fund (WWF).

The London group provided information on 32,000 wildlife populations which included more than 5,000 species. The researchers found that population sizes had declined by 69 percent on average. They said the loss of forests, human exploitation (开发) of the environment, pollution, and climate change were great causes of the loss. Land-use change is still the biggest threat to wildlife. However, the researchers added, ”if we cannot limit warming to 1.5“C, climate change is likely to become the dominant cause of biodiversity loss in the coming years.”

Wildlife populations in Latin American and the Caribbean Sea area were greatly affected. The research showed a 94 percent drop in those areas in over 50 years. Wildlife populations in river and lake habitats decreased the most. Freshwater populations have declined by an average of 83 percent since 1970. For example, one population of pink river dolphins in the Amazon River area of Brazil fell by 65 percent between 1994 and 2016.

These findings are a red flag that warns of a larger system failure on the horizon. Even one species’ population decline can affect other species, eventually impacting the ecosystem’s ability to function. Humans depend on a stable climate, predictable weather patterns, and productive farmland and fisheries to thrive (蓬勃发展), but the current trends are severe enough to threaten many life-sustaining systems.

Our future depends on reversing(扭转) the loss of nature just as much as it depends on dealing with climate change. And you can’t solve one without solving the other. Everyone has a role in reversing these trends, from individuals to companies to governments. If nothing changes, animal populations will undoubtedly continue to fall, driving wildlife to extinction and threatening the integrity (完整) of the ecosystems on which we all depend.

【推荐1】When I woke up on Aug 4, 2016, there was only one thing on my mind: what to wear. A billion thoughts appeared through my brain in the closet (衣橱). Not only was it my first day of high school, but it was my first day of school in a new state; first impressions are everything, and it was important for me to impress the people who I would spend the next four years with.

After carefully hunting my closet, I proudly came out in a dress from Target. The soft cotton was comfortable, and the specially designed shoulders added a little of fun. Yes, this cloth was the one. An hour later, I felt powerful as I headed toward room 1136. But as I entered class, my jaw dropped to the floor.

Sitting at her desk was Mrs Hutfilz, my English teacher, wearing exactly the same dress as me. I kept my head down and tiptoed(踮着脚尖) to my seat. I made it through my simple introduction speech until Mrs Hutfilz stood up, jokingly saying that she liked my style. Although this was the moment I had been afraid of from the moment I walked in, all my anxiety surprisingly melted away, and the students paid attention as I shared my story. My smile grew as I laughed with the students. After class, I stayed behind, talked to Mrs Hutfilz and make a humorous and real communication.

Looking back four years later, the ten minutes I spent afraid of giving my speech were really not worth it. My first period of high school certainly made the day unforgettable in the best way and taught me that Mrs Hutfilz has a brilliant sense of style!

【推荐3】Starting in the late 1980s, the plastics industry spent tens of millions of dollars encouraging recycling through advertisements and recycling projects, telling people plastics could be recycled. But their own internal records showed that industry officials long knew that plastic recycling on a large scale came with high costs but poor results.

A report sent to top industry directors in April 1973 said that plastic recycling was not as easy as people thought and sorting plastics was impractical. Another document a year later showed that there was serious doubt widespread that plastic recycling could get profits on an economic basis.

Despite this, three former top officials said the industry supports recycling as a way to beat back a growing trend of stopping using plastics in the 1980s. “The plastics industry is under fire, but we want to continue to make plastic products,” Thomas, an official from a company making plastics says, “If the public think the recycling is working, then they’re not going to be so worried about the environment.”

“The public gradually doubt the idea that the plastics industry could do a satisfying job in dealing with plastics and protecting the environment. But now we have already funded new technologies to change this situation. We don’t want to see the pollution of the environment either and are willing to solve this problem,” says Jim Becker, vice president of Chevron Phillips Chemical Company.

However, the more plastics are recycled, the less money the industry will make. And the industry now produces many more different and complex kinds of plastics that are more costly to sort and in many cases can’t be recycled at all. Efforts to reduce the use of plastics are increasing worldwide, but any plan to slow the growth of plastics will cause the whole industry to lose billions of dollars in the future.

【推荐2】The long-running Detective Conan (名侦探柯南) has a strong fan base on Asian TV today.

Detective Conan tells a story about a gifted high school student detective who turns into a young boy after he is forced to take a poison. He attends a primary school and together with detective Kogoro Mouri and his daughter Ran, Conan helps the police solve difficult mysteries.

Since1994, the comic (连环漫画) has grown up with the generation of 1980s and become an indispensable part of their childhood memory. Another well-loved series is coming back—Slam Dunk. The basketball-themed manga (动漫) from 1990 to 1996 is also a fond memory from childhood.

Many people said, “Now the basketballers are coming back, and so is the little detective boy. For a moment, I thought I was turning back the clock.”

Most people can relate with the two comic series because both of them attach importance to (重视) common values that we have when we were children.

The main characters in Slam Dunk are growing up and struggling with their dreams. There are courage, friendship and intelligence in Detective Conan. The return of the comic is a chance to remember who we once were.

It wasn’t until we were adults that we realized the world wasn’t what it looked like in comics. Time flies, but the young man we admire will always stay young.
