Food safety is a problem in all places around the world and people in different areas of the world prepare foods in different ways. The WHO released (发布) five simple rules for preparing food in a safe way. They call these rules the “Five Keys to Safer Food”.

Key 1: Keep clean

    {#blank#}1{#/blank#}People should wash their hands often — before touching food and while they are preparing food. People should wash all surfaces and equipment used for preparing food.

Key 2: Separate raw (生的) and cooked

    Raw foods should not touch prepared foods.{#blank#}2{#/blank#}.

Key 3:{#blank#}3{#/blank#}

    People should cook eggs and meat especially carefully. These foods may carry more micro-organisms (微生物) than other foods. Food like soup must be boiled for at least a minute to make it be cooked completely. It is also important that people re-heat cooked food completely.

Key 4: Keep food at safe temperatures

    When people finish eating, they should keep the left food in a refrigerator below 5℃and shouldn't store it for too long. At room temperature, about 20℃, the amount of micro-organisms can increase very quickly. But temperatures above 60℃ or below 5℃ control the growth of micro-organisms.{#blank#}4{#/blank#}.

Key 5: Use safe water and raw materials

    {#blank#}5{#/blank#}. Damaged or old food may develop harmful chemicals as it gets older.

A. Cook completely

B. This key tells about the importance of washing

C. Eat healthily

D. They can live where we make food

E. People should use safe water and choose fresh foods

F. They cannot grow as quickly in a very hot or very cold environment

G. People should use separate equipment and tools for touching and preparing raw foods

Common public speaking problems

    The use of "I feel", "I think" and "maybe"

    In the question-and-answer session of the speaking competition, many contestants began their answers with uncertain expressions like "I feel", "I guess", "I hear", "maybe" and "perhaps".

    These words show that the person is only speaking from his or her point of view. {#blank#}1{#/blank#} 

    Work on keeping your answers brief and to the point, {#blank#}2{#/blank#} . Instead of the empty-sounding "I guess", using facts, together with a clear conclusion based on those facts, is far more likely to be popular with an audience.

    Using only one speaking style

    Don't stick to the same tone. {#blank#}3{#/blank#} 

    For example, when they spoke about their dreams, some sounded romantic. Others used humor. Very few used several different styles together. Try mixing more than one style, rather than just sticking with the same one.

    Irresponsible answers

    Public speaking is different from personal conversations. You're responsible for your words. {#blank#}4{#/blank#} So you should think twice before you talk. Don't be like the student who, when asked about his opinion on book piracy（盗版）, started by saying he supported it.

    Talking around the topic rather than directly answering it

    You should focus on one point and give a clear solution. The key is to work out what question is being asked. Is it asking you to discuss a certain topic or to present your own point of view?

    Use one or two arguments together and give a strong conclusion. {#blank#}5{#/blank#} 

A. It can be boring. Try to mix it up.

B. Even though you want to answer quickly, you don't want to sound foolish.

C. Also work on delivering them with calmness and confidence.

D. Deliberate gestures and affected（做作的）expressions of feelings are improper in a successful speech.

E. Remember that judges are not judging you on whether they agree, but on your ability to say what you think clearly.

F. This lacks the support of facts and seems not to be reliable for the judges and audience.

G. Confidence is extremely important in public speaking as it lets a speaker sound more convincing.

    Jordan wakes at 6 a.m. She helps her disabled mother, who is recovering from surgery for breast cancer, into the bath. Jordan has it all timed. She has a quick breakfast as her mother bathes, and returns to help her out of the bathtub and into her room. Before going to school, the 14-year-old has to walk the dog. In the evening, Jordan takes care of the family's animals and helps her mother into bed. Then she had a chance to eat dinner, do homework and wind down before going to sleep. Bedtime can be past midnight for the Florida nine-grader.

    “You have to have a certain level of maturity (成熟) to do it,” She says. As a determined student, Jordan is already planning a career in medicine.

About 1.4 million children between ages 8 and 18 are caregivers nationwide, according to American Association of Caregiving Youth (AACY). Evenly divided between girls and boys, about a third are between 8 and 11, and nearly 40% are between 12 and 15. For the young caretakers, most common are chores like shopping, fixing meals and household tasks, or keeping the family member company. Hands-on care includes helping loved ones with day-to-day activities such as bathing, dressing and toileting, getting in and out of bed and chairs, and feeding.

    AACY is a nonprofit organization supporting caregiving kids in various ways, including financial assistance, caregiving education and camps to connect young caregivers to peers. Through AACY's Care Giving Youth Project, Jordan is not alone and she is able to develop friendships with teens like her. “I felt much more relieved and less embarrassed because I wasn't the only one.” She says. “I met one of my best friends and I'm still friends with her today.”

    There is light at the end of the tunnel for Jordan. “Seeing the people I'm taking care of become better gives me a relief that things will get better,” she says. She believes that AACY will continue to help her mother when it's time for her to go to college.

    Teachers' Day is, interestingly, not celebrated on the same day all over the world. In some countries it is marked by a holiday, in others it is a working day.

    International Teachers' Day is celebrated on October 5. Being held ever since 1994, it is in honor of teachers' organizations worldwide. Its aim is to encourage supports for teachers and to meet the needs of students.

    China   In 1939, Teachers' Day was set for August 27, Confucius' birthday. In1951, the celebration was stopped. However, it was founded again in 1985, and the day was changed to September 10.

    India   Teachers' Day is celebrated on September 5 in honour of Dr. Sarvepalli Radhakrishnan, the second president of India, whose birthday falls on that day.

    Russia   In Russia, Teachers' Day was celebrated on the first Sunday of October between 1965 and 1994. Since 1994, the day is observed on the October 5, just the same day as World Teachers Day.

    The US   In the US, Teachers' Day is non-official holiday. It is celebrated on the Tuesday of the first full week of May. A number of activities are organized in schools to honor teachers. The celebrations can continue for the whole week of May.

    Thailand   In Thailand, National Teachers' Day is celebrated every year on January 16. The first Teachers' Day was held in 1957. The day is a holiday in schools.

    We all need to eat. So, meals could be a chance to stop what we're doing and spend time with the people in our lives. A recent study from a team of South Korea suggests that eating together has many good effects on children and teenagers while frequently eating alone may lead to poor eating habits and poor food choices. People who eat alone more than twice a week have a greater risk of developing high blood pressure.

    There are benefits of family dinners on children and teenagers.

    In 2014, the Organization for Economic Cooperation and Development (OECD) looked at data from nearly three-quarters of the world's countries. Among its findings is the fact that students who share a main meal with their families are less likely to hate school. Children who eat a main meal with their families are also less likely to take drugs (毒品).

    In the report, titled "The Importance of Family Dinners (VIII)," researchers say that teens who have frequent family dinners are more likely to say their parents know a lot about what's going on in their lives.

    Another study from the University of Montreal finds that children who eat with their families experience long-term physical and mental health benefits. These children are physically in better shape and drink fewer sugary soft drinks. These children also seem to have better social skills and are less violent.

    One of the researchers, Pagane, involved in this study is a professor at the university. She says that mealtimes with parents possibly provide young children with firsthand social events, which helps them have better communication skills.

    There's a man in the habit of hitting me on the head with an umbrella. At first I couldn't stand it, now I'm used to it.

    I don't know his name. I know he's average in appearance, wears a gray suit, and has a common face. I met him five years ago one hot morning when I was sitting on a tree­shaded bench in Palermo Park, reading the paper. Suddenly I felt something touch my head. It was the very same man who now, as I'm writing, keeps hitting me, mechanically (机械地) and impassively, with an umbrella.

    On that occasion I turned around filled with anger. He just kept on hitting me. I asked him if he was crazy, he didn't even seem to hear me. Then I threatened to call a policeman. Calmly, cool as a cucumber, he stuck with his task. After a few moments of hesitation, and seeing that he was not about to change his attitude, I stood up and hit him on the nose. The man fell down, but he immediately got back on his feet, obviously with great effort, and without a word again began hitting me on the head with the umbrella. His nose was bleeding and, at that moment, I felt sorry for him. I felt regret for having hit him so hard. After all, the man wasn't exactly hitting me; he was merely tapping me lightly with his umbrella, not causing any pain at all. Of course, those taps were extremely bothersome. As we all know, when a fly lands on your forehead, you don't feel any pain; what you feel is annoyance. Well then, that umbrella was one huge fly that kept landing on my head time after time.

    Convinced that I was dealing with a madman, I tried to escape. But the man followed me, wordlessly continuing to hit me. So I began to run (I should point out that not many people run as fast as I do). He took off after me, trying to land a blow. The man was out of breath so that I thought, if I continued to force him to run at that speed, he would drop dead right then and there.
