The search for one of life's greatest goals, happiness, is what brings almost 1,200 students to one of Yale University's most popular classes ever. {#blank#}1{#/blank#}Psychology professor Laurie Santos teaches the class.

    One in four Yale undergraduate students has registered to take it. It has the largest class registration size in Yale's 317-year history. {#blank#}2{#/blank#}Santos says it is the hope that science can help students find peace among all the stresses and difficulties they face at college. "Students report being more depressed than they have ever been in history at college," she said.

    Social science research has led to many new understandings of how people find happiness, Santos says. {#blank#}3{#/blank#} she said of the students taking her happiness class.

    Santos said feelings of happiness are created through several things. {#blank#}4{#/blank#} She added that while many people may see money and possessions as goals in life, those things are not usually what make people most happy. School work for the happiness class, also known as Psyc157, includes showing more gratitude, performing acts of kindness and increasing social connections. Because of the popularity of the class, it has been made publicly available -- for free – on the website Coursera.

    The class is already helping Yale students like senior Rebekah Siliezar. {#blank#}5{#/blank#}"What's most pressing on our minds is grades, it's the next job, it's a potential salary after graduation," said Siliezar. Now, she said tries more to "focus on the present moment and the people around me."

Meat-free Mondays

    In the United Kingdom, vegetarianism (素食主义) is becoming very popular, with around 3 million people in the UK vegetarian.{#blank#}1{#/blank#}However, here in France, I often struggle to find a meat-and-fish-free choice on a menu, which can make eating in restaurants a bit of a challenge.

    People are often curious why I choose to limit my diet in the way I do. There are many reasons why people may choose to be vegetarian. Many people give up meat or fish simply because they do not enjoy the taste. {#blank#}2{#/blank#} They believe it has a bad effect on the environment or it is bad for health. Furthermore, many people are vegetarians to avoid wasting food. In addition, some religious beliefs forbid eating certain meats. {#blank#}3{#/blank#}

    {#blank#}4{#/blank#}However, although sometimes vegetarian food requires a little more creativity, it is very easy to enjoy a healthy and balanced diet as a vegetarian especially when meat substitutes (替代品) are becoming much easier to get.

    Meat-free Mondays is a campaign (运动) to encourage every family to eat just one main meal a week which does not contain meat or fish. {#blank#}5{#/blank#}This is a great challenge for anyone who would like to try out some vegetarian cooking and is a wonderful way to contribute to slowing down climate change.

A.   Young kids prefer meat and fish than vegetables.

B.   Some feel that killing animals for meat is wrong.

C.   Vegetarian food can be delicious and easy to prepare.

D.  The city where I grew up is known as the „vegetarian capital' of the UK.

    Running is a great way to get in shape and just about everyone can do it. Given that it's so easy to take up the sport, a lot of beginners jump right into running without actually knowing what it takes to establish a healthy routine.{#blank#}1{#/blank#}. If you are just starting out, avoid the following things to help you increase your chances of running success.

    Doing too much too soon

    One of the biggest mistakes beginners make is doing too much too soon. Picking up a new hobby like running is no doubt exciting. Runners need to ease into the sport before increasing the distance.{#blank#}2{#/blank#}.

    {#blank#}3{#/blank#}.

    Beginners might think they need to run nearly every day to meet their fitness or weight-loss goals, but this couldn't be further from the truth. {#blank#}4{#/blank#}, especially for beginners whose muscles and bones haven't  yet been conditioned for such intense (剧烈的) exercise. So it's important to give your body ample rest between workouts. Follow a training plan that includes rest days.

    Comparing yourself to others

    {#blank#}5{#/blank#}. You're excited about running, so you are probably reading running blogs, magazines and message boards where you might start to feel inadequate about your own running pace. Instead of getting down on yourself, remember that every runner was once a beginner and use their success as motivation!

A. Not taking rest days

B. Not running every day

C. As mentioned, a healthy routine is what they attach importance to

D. Running is a demanding activity which can be really hard on your body

E. When starting out with running, it's tough not to compare yourself to others

Home libraries can be a dynamic expression of the owner's personality. Creating a home library is a fun way to display your interests while establishing a special space for reading.

While there's no right or wrong way to design a library, the questions can be puzzling, especially to someone with hundreds or thousands of books. How do I organize?{#blank#}1{#/blank#} We'll discuss how to build a home library that works for you.

What room should I use for my home library?{#blank#}2{#/blank#} While reading in a room with big windows and lots of light is refreshing, storing books in natural light is harmful to them. Basements heavy with humidity (湿气) will cause mold (霉菌) and attract insects.{#blank#}3{#/blank#}

When you started using the public library, you probably learned about Melvil Dewey and his system for ordering libraries. The Dewey Decimal Classification System has ten broad categories for organizing books, including philosophy, religion and the arts.{#blank#}4{#/blank#} For example, when you want a book on modern art, you head to the 700th block. Larger libraries, such as those at universities, tend to use the Library of Congress Classification System, because it offers a more specific array of subjects for categorization, adding subjects such as medicine and law for a total of 21categories.

{#blank#}5{#/blank#} Your home library may or may not be as large as your local public library, but a good system of organization will still help you find the book you want quickly. You could take a page from Dewey and the Library of Congress and sort books by subject matter. Sections for subjects such as history, technology or fiction might make their retrieval (检索) easier. This system will also allow you to highlight a particular passion, such as an extensive collection of World War II history,

A. How do I get everything to fit?

B. Each category is assigned a number.

C. Almost everybody wants a home library.

D. A good system of organization is the key.

E. In addition, basements are likely to be flooded.

F. Almost any room will do with a few exceptions.

G. The size of a home library depends on how much space you can spare.

Make new friends.

No matter where you end up studying abroad, take this time to make new friends. That could mean someone from your school in your program or major.

Overcome homesickness.

No matter where you go, you'll probably get a little homesick. {#blank#}3{#/blank#} Luckily for you, with social media, you can connect with your loved ones almost instantly at any time of the day. Besides, we're almost positive that everyone back home misses you just as much as you miss them. However, they probably want you to enjoy yourself as much as possible and not to feel sad because you miss them.
