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

    Shorts may feel nice and casual on your legs on a warm summer's day, but they're not so gentle on your wallet.{#blank#}1{#/blank#} Usually the fact that one obviously uses less cloth than the other makes it hard to be accepted. So what gives?

    It turns out clothing sellers aren't trying to cheat you by charging you too much money. They're just pricing shorts according to what it costs to produce them.{#blank#}2{#/blank#} Extra material does go into a full pair of pants but not as much as you may think. As experts explain, shorts that don't fall past your knees may contain just a fifth less cloth than ankle-length trousers{#blank#}3{#/blank#}

    Those same details that end up accounting for most of the material—pockets, belt loops, waist bands—also require the most human labor to make{#blank#}4{#/blank#} The physical cotton in blue jeans accounts for just a small part of its price Jag. Most of that money goes to pay the people stitching (缝合) it together, and they put in roughly the same amount of time whether they're working on a pair of pants or some shorts.

    {#blank#}5{#/blank#} For another example, short-sleeved shirts cost roughly the same as long-sleeved shirts. There are also numerous invisible factors that make some shorts more expensive than nearly identical pairs, like where they were made9marketing costs, and the brand on the label. If you don't want to spend $40 on something that covers just a small piece of leg, stay at home with your wallet!

A. More or less, shorts almost cost what pants do.

B. This is where the true cost of a garment is determined.

C. This price trend becomes popular across the fashion field.

D. This is because most of the cloth is sewn into the top half.

E. In general, a pair of shorts isn't any cheaper than a pair of pants.

F. To tell you the truth, it is a real bargain to pay for a pair of shorts.

G. Customers are willing to purchase a pair of shorts if it is at a reasonable price.

    Planning before buying something is a good idea. For example, you are going to buy a pet dog, you still have to consider a few things and plan them well before you welcome it in the house. {#blank#}1{#/blank#} You will also have to train it well so that it does not misbehave in front of people. You should realize that it is a big responsibility.

    {#blank#}2{#/blank#}Think about whether your pocket can manage the purchase, as well as different items for keeping the dog. If something goes wrong with the health of your pet, you will have to spend some extra money on it.

    The next thing you need to consider is your home, {#blank#}3{#/blank#}You will also have to consider the family members. If your living place is already too crowded with people, getting a dog as an additional member of the house will not be a good idea.

    {#blank#}4{#/blank#}Make sure nobody is allergic(过敏的) to the fur of the dog. Also make sure that you can easily find time to train the dog. Ensure that your family is welcoming to this idea.

    {#blank#}5{#/blank#} When you are bringing this best friend in your house you must make sure everything is right for it. You should make life easier for it, as well as others who are living in your house.

A. Looking after your dog doesn't only mean taking it for a walk or playing with it.

B. A dog is supposed to be man s best friend.

C. Before you think about getting a dog, think about the afford ability(经济承受力).

D. The training should start as soon as the dog is in your care.

E. Once the dog has learned how to sit, you may teach him to shake hands.

F. You will also have to think about any health problems related to your family.

G. A small apartment will not be fit to house a large dog.

    It can be difficult to meet new people and make friends, especially when you move to a new city or find yourself out of your comfort zone. How will you deal with the situation?{#blank#}1{#/blank#} There are several ways that you can meet people that you might not have considered in the past.

    {#blank#}2{#/blank#}You probably have several acquaintances that you see on a daily basis or a weekly basis. If you get along well with certain people, you can see if this acquaintance would like to go out and do something socially with you. If you have common interests, you might suggest that the two of you do something together that involves your interest.

    Make an effort to accept invitations. Sometimes people that you know may be having a barbecue or other types of social gathering. Try to ensure that you are able to attend and then show up at the appointed time.{#blank#}3{#/blank#}If you meet people that you click with, you can make a plan to see them again in the future or you can invite your friends to your own event and ask them to extend the invitation to the friends that were at their gathering too.

    Go out, even when you don't feel like it. It turns out that when people invite someone to join them for dinner or a movie or something else, they really want to hang out with you.{#blank#}4{#/blank#}

    Do you want to create more successful writings? Perhaps you can benefit from the following suggestions on excellent writing.

    You need time. A lot of smart people lie to themselves like, “I finish my task best at the last minute.” In fact, it's not true. {#blank#}1{#/blank#} Sure, you are smart, but you still need to have some pressure. For example, if you are working on an important topic, why do you think that you can write well at midnight just before the conference? Writing can be a miracle if you are given enough time.

    Writing requires practice. {#blank#}2{#/blank#} Would you do nothing before running a marathon? No, you would practice running gradually to make your body stronger. In order to become a writer, you need to write.

    {#blank#}4{#/blank#} Or, at least, they are not correct to some extent. Nearly all of the best scholars are changed by their experiences in doing research and writing about it. They learn by doing, and sometimes what they learn is that they were wrong.

    Revise your writing again and again. Have other people look at it. You need to overcome a fear of refusal. {#blank#}5{#/blank#} The difference between a successful scholar and a failed one is about who is better at writing and revising.
