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

    English can be a difficult language to learn, but there are certain things you can do to learn the language a lot faster. People can master English as long as they take the time to practice speaking, reading and writing in English. {#blank#}1{#/blank#}

    Start by taking a class that teaches beginning English. These classes are often named as “ESL” classes, or “English as a Second Language.” {#blank#}2{#/blank#}

    Buy an English audio(音频的) course. You can go over these classes in your spare time and learn quite a bit. Buy an audio course and listen to it in the car or while working, if possible. The higher the quality of the course, the quicker you'll learn.

    Practice speaking English with other people, especially with native English speakers. {#blank#}3{#/blank#}And make sure they are willing to help you learn English by having simple conversations with you. You will probably be surprised at how quickly you can start having a conversation in English.

    {#blank#}4{#/blank#} Pay attention to the dialogue and try to figure out what the actors are saying. Congratulate yourself when you are able to pick out certain words and phrases that you understand.

    Read newspapers, books and magazines that are printed in English. At first they maybe very difficult, but as your knowledge grows so will your understanding of written English. {#blank#}5{#/blank#} It will help you a lot in learning to speak the language much faster.

A. Try to understand written English.

B. Watch television shows or movies that are in English.

C. Read and remember as many English words as possible.

D. Here we will show you how to learn to speak English quickly.

E. Every morning you should get up very early and read English.

F. Make friends with people speaking English as their native language.

G. The teachers of these classes have the experience to teach the students.

    Perhaps you've heard the old saying “curiosity killed the cat.” It's a phrase that's often used to warn people—especially children—not to ask too many questions. {#blank#}1{#/blank#}In fact, research has shown that curiosity is just as important as intelligence in determining how well students do in school.

    Curiosity can also lead us to make unexpected discoveries, bring excitement into our lives, and open up new possibilities. {#blank#}2{#/blank#}For example, one day in 1831, Michael Faraday was playing around with a coil(线圈) and a magnet(磁铁) when he suddenly saw how he could produce an electrical current. At first, it wasn't clear what use this would have, but it actually made electricity available for use in technology, and so changed the world.

    {#blank#}3{#/blank#}On one level, this is because technology has become so advanced that many of us are unable to think too deeply about how exactly things work anymore. While it may be possible for a curious teenager to take a toaster apart and get some sense of how it works, how much do you understand about what happens when you type a website address into a browser? Where does your grasp of technology end and the magic begin for you?

    In addition to this, there's the fact that we all now connect so deeply with technology, particularly with our phones. The more we stare at our screens, the less we talk to other people directly. {#blank#}4{#/blank#}Then we feel we know enough about a person not to need to engage further with them.

    The final—and perhaps most worrying—way in which technology stops us from asking more has to do with algorithms, the processes followed by computers. As we increasingly get our news via social media, algorithms find out what we like and push more of the same back to us. {#blank#}5{#/blank#}Perhaps the real key to developing curiosity in the 21st century, then, is to rely less on the tech tools of our age.

A. It is still not known why learning gives us such pleasure.

B. We are always encouraged to challenge our pre-existing beliefs.

C. Yet it's widely agreed that curiosity actually makes learning more effective.

D. All too often we accept the images of people that social media provides us with.

E. However, curiosity is currently under the biggest threat, coming from technology.

F. In science, basic curiosity-driven research can have unexpected important benefits.

G. That means we end up inside our own little bubbles, no longer coming across new ideas.

How to Take Notes?

    Note-taking is a skill which can be used right from primary school up until you leave university or {#blank#}1{#/blank#} If you follow these simple steps and tips, you will not only learn how to take notes; you will succeed or perhaps even come up with your own method!

    Note details at the top of your paper. Keep your notes organized by writing important details at the top of each page. {#blank#}2{#/blank#} Noting details can make it easier for you to return to your notes and get important information.

    Use your own language. Write down key facts, ideas, and details in your own words. Taking notes in your own words actively engages your brain and helps you better understand the text. Develop your own system of signs and short forms that can help you more quickly take notes and review them. {#blank#}3{#/blank#}

    {#blank#}4{#/blank#} Think about the text you're reading or the lecture you're listening to—they may be a bit hard to understand. Avoid using full sentences when you write your notes. Instead, use keywords to say the same things in a short and manageable way that you can easily and quickly review later.

    Skip lines on the paper for later review. {#blank#}5{#/blank#} Having extra room allows you to make additional notes or clarify points that you may not understand. This helps you quickly have and identify all of the relevant material to that keyword or thought.

A. Review your notes later in the day.

B. Write keywords instead of full sentences.

C. For example, “SM” for “scientific method,” or “GH” for “gender history”.

D. As you write your keywords and ideas down, leave space between each line.

E. It may seem challenging to take notes quickly while keeping key information.

F. Include information such as the date, bibliographic information, and page number of your notes.

G. Good note-taking is a valuable skill for keeping, remembering, reciting and recalling information.

    We all have to make decisions all the time, and we have an abundance of choices, ranging from tiny issues to vital ones. {#blank#}1{#/blank#} That means the skill of good decision-making counts a lot. If you would like to improve your skill of decision making, here are four suggestions for you.

    Don't expect to have it all.

    Decisions force us to close the door on other possibilities. {#blank#}2{#/blank#} And there will be paths not taken, careers not chosen, to name a few. You can imagine some "what if" situations if you must, but do not let them take up too much space in your brain.

    {#blank#}3{#/blank#}

    It's often good to think through your decisions. But don't overdo it. Research can reach a point where returns begin to reduce, which makes it confusing more than clarifying. Many good decisions can be made based as much on intuition (直觉) as on careful assessment of endless data.

    Don't delay making decisions.

    Yes, there is a time to put off making a decision. Perhaps you need more information. {#blank#}4{#/blank#} Or it's likely that you wait for a less stressful time. Just don't wait so long that the decision is made by your own indecisiveness.

    Don't be hard on yourself.

    You decide to go on a voyage. You choose an expensive liner. Everything should work out just right. Only you didn't expect a bug that ran around on the ship, making you and your family sick for five days. {#blank#}5{#/blank#} But please remember it is unavoidable sometimes.

    If you just moved, you might be wondering who lives in your neighborhood. It's always a nice surprise to learn that there are families similar to your family close by. {#blank#}1{#/blank#} Here are some tips on how to make a good first and lasting impression.

    Do a Drop and Hi. Within the first few weeks of getting settled, consider dropping a small baked good or local treat with a card that includes your phone number and name. {#blank#}2{#/blank#}

    Host Something. Once you are on a first - name basis with a few of your neighbors, consider hosting a small meet and greet event. Do something outside like a BBQ to keep things simple and relaxed.

    {#blank#}3{#/blank#} It's always such a nice gesture if you help your neighbor with bringing in their garbage can or ask if you can help carry groceries, etc. Ask if you can help or suggest they borrow one of your tools. Being considerate goes a long way.

    Exchange Numbers. It's important to exchange numbers, especially if you or your neighbor may be traveling. {#blank#}4{#/blank#}

    Good neighbors become friends and always watch out for each other. {#blank#}5{#/blank#}

A. Help When You Can.

B. Hold a Positive Attitude.

C. It's no good having a face - to - face talk.

D. You can then tell them if you see anything wrong happening.

E. A "looking forward to meeting you" type note is always nice.

F. But how do you make sure you're the kind of neighbor people want to spend time with?

G. With these tips, you'll find yourself with a good community of close friends in no time.
