A student's life is never easy. {#blank#}1{#/blank#} A lot of preparations are needed so you can be sure to go back home with a diploma and a bright future waiting for you. The following are some basic things you need to do before even seizing that passport and boarding on the plane.

Knowing the country.

    You shouldn't bother researching the country's hottest tourist spots or historical places. You won't go there as a tourist, but as a student. It'll be helpful to read the most important points in their history and to read up on their culture. {#blank#}2{#/blank#} You surely don't want to face legal problems, especially if you're away from home.

Studying their language.

    Don't expect that you can graduate abroad without knowing even the basics of the language. Before leaving your home country, take online lessons to at least master some of their words and sentences. {#blank#}3{#/blank#} Doing this will also prepare you in communicating with those who can't speak English.

{#blank#}4{#/blank#}.

    Check the conversion（兑换）of your money to their local currency, set up your bank account so you can use it there, get an insurance, and find an apartment. The Internet or your intended school will be very helpful in finding an apartment and helping you understand local currency.

    Remember, you're not only carrying your own reputation but your country's reputation as well. If you act foolishly, people there might think that all of your country men are foolish as well. {#blank#}5{#/blank#}

A. Packing your clothes.

B. Preparing for other needs.

C. Most importantly, read about their laws.

D. This will be useful in living and studying there.

E. That would surely be a very bad start for your study abroad program.

F. Going with their trends will keep it from being too obvious that you're a foreigner.

G. And it is even more difficult if you will have to complete your study in a foreign land.

    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

    An interesting study posted on Facebook recently shows how men and women develop new interests as they mature(成熟).

    While women tend to take exercise seriously from the age of 34, men will wait until their 45th birthdays before working hard to get in shape. The average woman spends more time talking about sports, politics, career and money as she gets older.

Women's interest in books reaches its peak(顶峰) at the age of 22, while that of men does so when they are in their 50s.

    Men start to change their focus from the workplace to other things after age 30, while women do not do so until eight years later. Both, however, care most about fashion at age 16.

    The research used anonymous(匿名的) data donated by thousands of Facebook users, recording the statuses, 'likes' and 'interests' they had posted on their profiles.

It found the average woman talks about television most at 44, while men peak much younger, at age 31.

    Men are also most likely to see a film in a cinema at age 31, while women go out to see films most when they are only 19.

    Men are most interested in travel at 29, women at 27, while women talk most about food and drink at 35, and men at 38.

    And if you are middle aged, a safe topic for any audience is the weather, which is a key interest for many as they approach 60.

    Stephen Wolfram, the British scientist who carried out the research, says, “It's almost shocking how much this tells us about the changes of people's typical interests.

    “People talk less about video games as they get older, and more about politics.”

    The National Postal Museum is divided into galleries that explore America's postal history. Visitors will have a full picture of the creation and fantastic varieties of postage stamps.

    World of Stamps

    Video images bring stamps to life and attract visitors who explore the surrounding displays. Visitors encounter the world's first postage stamp — the 1840 Penny Black and learn how it revolutionized communication. Stamp images, including Dr. Martin Luther King's "I have a dream" speech and the stamp that helped raise almost $72 million dollars for breast cancer research, explain how stamps have shaped history and honored people and places worldwide.

Gems of American Philately

    Visitors have the opportunity of examining 13 of the most rare and highly valued stamps in the world of the stamp collection, including the most famous American stamp of all, the 1918 Inverted Jenny. A video explains why the Inverted Jenny and other stamps displayed here are the most valuable. The treasures in this area are rarely available for public viewing. Each tells a story about an important event in US history.

    Mail Marks History

    The markings on mail provide valuable clues to the surprising ways mail has been transported over time, including challenges and even disasters encountered along the way. You will understand these markings by following the journeys of three historic letters.

    Connect with US Stamps

    Visitors explore their own connections with stamps. At three touch screen tables, they create their own stamp collection based on the topics that interest them most. They can also create their own stamp designs. Visitors have the chance to view videos in which stamp designers talk about their craft, stamp collectors explain what they collect and why, and footage(片段) shows the process of making stamps.

    LONDON Tuesday April 11—Dustin Hoffman fan Pamela Crack got the shock of her life when the movie star telephoned her as she was doing her housework.Crack, 58, said she was "flabbergasted" when she picked up the phone and heard the star at the other end.

    "It's not every day you get a Hollywood superstar phoning you when you're doing the housework," Crack told the Sun."It was a moment I'll never forget."

    Hoffman was in the back of a London taxi driven by Crack's husband, Dave, when he made the call after being told Pamela was a fan. Dave Crack later became the star of Hoffman's speech at the Bafta award ceremony Sunday, where the 62-year-old American actor presented the Best Film award.

    "He said to give him a mention," Hoffman told the audience to a burst of laughter. "Cheers Dave."Taxi driver Crack said the Hollywood star was a joy to drive from the moment he got into the taxi eating a cheese and tomato sandwich.

    "I said 'You're that Dustin Hoffman, aren't you?' and he said, 'Yes I am—would you like a sandwich?' I was a bit surprised but I took a sandwich from him and ate it hungrily."

    We have heard some interesting ways that 5G wireless technology might change our lives in the future.

    5G, short for the 5th generation mobile communication technology, promises Internet speeds between 50 to 100 times faster than current 4G systems. While 5G is set to be used in some limited areas of America this year, much of the world is not expected to receive widely available service until 2023.

    One project in Britain, however, is already testing this superfast technology on an unlikely group of Internet users-cows. The project was developed by American technology company Cisco Systems. It also receives money from the British government. Cisco says the program seeks to explore the future of 5G connectivity in rural areas around the world.

    Testing areas were set up at farms in three rural areas of England. The cows are equipped with 5G-connected devices (装置) that link up to a robotic milking system, which uses sensors and machine learning to fully automate the process. System designers say technology takes over after a cow feels ready to be milked and walks toward an automatic gate. The device is designed to recognize each individual cow. It then positions equipment to the right body position for milking. During the process, machines release food for the cow as a reward.

    Other 5G technology tools include automated brushes that turn on when the cow rubs up against them. Sensors also control the amount of light to the cows' living areas depending on the weather. And, an automatic feeding system makes sure the animals always get enough to eat.

    Duncan Forbes, head of the project, told Reuters that the project shows the farm's cow operations can be greatly improved with 5G technology and that the experiment provides strong evidence that 5G technology can be widely used in the future, not just on farms in Britain, but in rural communities across the world.
