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

    You might dream of fluency in this or that language, and maybe you've already achieved fluency in a foreign language.{#blank#}1{#/blank#}.

    Fluency, like all abstract terms, has no universal meaning. Each individual must determine what the term means.{#blank#}2{#/blank#}.

    Perfect fluency means knowing every word you encounter, speaking quickly, clearly and easily and having no accent.{#blank#}3{#/blank#}. You aren't familiar with every word of your native language, and sometimes you have to search for the right word, even in your mother tongue.

    Quick fluency is the type of fluency you see in advertisements, because “Master a Language in Two Months!” sounds way catchier than “Fluency in Twenty Years!”{#blank#}4{#/blank#}. It is possible to achieve quick fluency, but the fluency achieved after such a short time frame will be a very thin, superficial fluency.

    {#blank#}5{#/blank#}. Native-like fluency means that you generally know all the same words that a native knows and can speak at the same pace with the same amount of ease as a native speaker. You will likely have an accent, but as long as your conversation partner can understand you, it doesn't matter.

    Literary fluency is like graduating from native-like to educated-native-like fluency. It focuses on the more intellectual（知识性的） side of a language: indulging in literature, attending university, composing song lyrics, etc.

    There are a ton of other things that fluency could potentially（可能地） be, but that's up to you to figure out.

A. It sounds too good to be true.

B. However, Nobody is “perfectly fluent” in any language.

C. Quick fluency is good if you have some sort of deadline.

D. But have you ever considered what fluency really means?

E. But does fluency have the same meaning to other person as it does to you?

F. Unlike perfect fluency, native-like fluency is a reasonable and attainable goal.

G. To assist you in determining what fluency is, I'll describe a few different types of fluency.

Five Things Nobody Told Me about College

    As I type this, I am in my university dorm room. A year ago, when I was awaiting to hear the results of my college applications, I often went to websites for some type of insider look on what college would be like. However, there's only so much that prep books, websites, and older friends can teach. Here are the top 5 things nobody told me about college:

    {#blank#}1{#/blank#}

    Nobody entering a university knows exactly what they want to study. If they tell you otherwise, they're lying and will probably change what they want to purse within the first quarter of attendance. During my first quarter at University of California, Riverside (UCR), I thought that I wanted to study Political Science with its focus on International Affairs, so that's what I applied for. However, once I worked with statewide and local government, I realized that a better fit for me would be Public Policy, and now I am in the process of changing my area.

    {#blank#}2{#/blank#}

    In college, there are so many good chances for you to meet your expectations. However, there is a very important difference between wanting to do something and applying for something. In order for you to take advantage of the conferences, research, internships, and fellowships that your university offers, apply! Step into your academic advisor's office, introduce yourself, and begin making the valuable connections that are necessary to help during the rest of your college career. Great things happen when you step out of your comfort zone, and you would be surprised on how many chances exist if you just ask.

    {#blank#}3{#/blank#}

    College is where you meet your bridesmaids, neighbors, and potential bosses. The relationships you develop now will probably be linked to the ones you value later, so be wise about the people who you invest yourself in. You are only one person, and you do not have time to waste on people who would rather cause drama or mess up with your purpose. Surround yourself with uplifting individuals who challenge you to be better while loving you for who you are, and be patient to the people who are the complete opposite of that description.

    {#blank#}4{#/blank#}

    As a first-year, I was afraid to make any noise towards campus issues that I noticed. It was not until I became involved in student government that I gained the confidence to handle projects that I created with the help of ASUCR Office of the President. During my first quarter, I spoke directly to the Chancellor, asking him for support towards my initiatives, met with the Vive Chancellors, and cooperated with my teaching assistances to begin my undergraduate research protect. Nothing good will happen when you are silent.

    {#blank#}5{#/blank#}

    At my high school, there were about only four active club and organizations that students could be a part of. Imagine my surprise when I stepped foot onto UCR's campus, where over 400 organizations exist, ranging from political organizations to karate club. You are not paying all or your tuition(学费)to merely go to class, study, pass tests and graduate. Make something worthy out of your experience. Create that you will want to tell your grandchildren one day. It all begins here, by signing up to join an organization.

A. Get involved in student activities

B. Your voice is actually super important

C. There is a significant increase of opportunities

D. Stay in active communication with your friends

E. Get smart about the people who you spend your time with

F. Your major does not matter as much in your first of college

G. College life is meaningful.
