China is a land of bicycles. At least it was back in 1992 when I traveled the country. Back then everyone seemed to be riding a bicycle. Millions of them，all black. Cars were rare. Yet since my arrival in Beijing last year，I've found the opposite is true. There are millions of cars. However，people still use their bicycles to get around. For many，it's the easiest and cheapest way to travel today. Bicycles also come in different colors—silver，green，red，blue，yellow，whatever you want.

    It's fun watching people biking. They rush quickly through crossroads，move skillfully through traffic，and ride even on sidewalks（人行道）.Bicycles allow people the freedom to move about that cars just can't provide.

    Eager to be part of this aspect of Chinese culture，I decided to buy a bicycle. Great weather accompanied my great buy. I immediately jumped up on my bicycle seat and started home.

    My first ride home was orderly（守秩序的）．To be safe，I stayed with a “pack”of bikers while cars on the streets came running swiftly out of nowhere at times.I didn't want to get hit. So I took the ride carefully.

    Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States. The streets here were wide，so crossing took time，skill and a little bit of luck.

    I finally made it home. The feeling on the bicycle was amazing. The air hitting my face and going through my hair was wonderful. I was sitting on top of the world as I passed by places and people. Biking made me feel alive.

    Philadelphia offers a ton of attractions that are suitable for people of every age and here are some family—friendly attractions.

    Spruce Street Harbor Park

    Spruce Street Harbor Park, one of the best urban beaches in America, is an outdoor heaven on the Delaware River waterfront. Visitors can relax in a hammock, play on the playgrounds, and play games like table tennis and giant chess. Don't miss out on the park at night, when colorful LED lights hanging from treetops make the entire area bright.

    With exams just around the corner, now is a good time to explore some of UCL's lesser-known study spaces and get down to some revision. Here are some good choices for you.

    UCL Senate House Hub

    UCL Senate House Hub opened in 2015 and provides 144 study spaces. What's more, you can check how many spaces are available online before you head to the hub! Located on the third floor of the South Block of Senate House, the center has room for individual and group study in traditional library spaces, as well as casual armchairs and bar-style desks.

    UCL Eastman Dental Library

    The newly refurbished(翻新的) UCL Eastman Dental Library is located halfway along Gray's Inn Road and is open from Monday to Friday, 9:00 am–8:00 pm. The library has 72 study spaces, and many IT facilities are available. The library also has a study room for meetings and a computer room with an interactive whiteboard.

    UCL Language & Speech Science Library

    UCL Language & Speech Science Library (Lass) has disabled access and has recently been refurbished to add extra study spaces. With only 49 spaces, Lass is smaller than most other UCL Libraries and tends to fill up relatively quickly, so get there early to avoid disappointment.

    Senate House Library

    This one may be cheating as the Senate House Library is not technically a UCL library. However, all UCL students and staff can register for free membership online. With millions of books and journals, Senate House Library offers some places a little less used by UCL students but perfect for getting down to some hard work.

    I think a close friend is someone you get on well with, who helps you when you have problems, who gives you advice, and who always has time for you. I didn't use to have many close friends when I was at school because I was very shy, but now I have several. They are all women. I think it's difficult to have a close friend of the opposite sex（异性）.

—Marie

    I think a close friend is someone who you've known for a long time, and who you still get on with. They have similar hobbies to you so you can do things together. I've got three close friends who I was at middle school with and we often go out together （without our parents of course）. We often go camping, play football, or walk outside in the open air.

—David

    I'm not sure how to answer the question because I don't really have any close friends. I know a lot of people but mainly through work, and the social occasions（场合） when we meet are business dinners, things like that. I think if you come from a really close family, friends are a bit unnecessary. I like spending my free time with my family.

—Richard

    For me close friends are the people you spend your free time with. I go out at weekends with a group of people, and they are all my close friends. They're also people who live near me. I don't think you can have close friends at a distance because you need to be able to see each other often. But I don't think you need to be doing the same things. I mean I'm at school but none of my friends are.

"Don't get dirty!" was once often shouted by parents angrily watching their children ruin their best clothes. It was unavoidable that children's whites would turn brown before the day was over. 

Today, many parents may secretly wish their children had the chance to pick up a bit of dirt. With the rise of city life, and the attraction of video games and social media, contact with nature is much less than in the past. For many, there is simply no opportunity to get muddy. According to recent research, the dirt outside is teaming with friendly microorganisms (微生物) that can train the immune (免疫的) system and build the body against illnesses, such as anxiety. 

These findings show that outdoor exercise is not only beneficial because of the chance to run around free—but that certain natural materials, such as soil and mud, also have powerful microorganisms which have positive effect on children's health. Outdoor play can also offer valuable learning experiences. For example, the act of rubbing and shaping materials like mud or sand can help children develop their senses and movement. 

Such activities—away from the house or classroom—may also help children to find ways to deal with emotions that may be hard to explore in other environments. So-called "Sandtray Therapy (沙盘疗法)", which includes using sand to express one's thoughts and feelings, is an accepted form of guidance for children who are struggling to speak out their inner emotions. 

Surprisingly, people who spent most of their childhood in the countryside show a better reply to stressful events like public speaking compared with those who grew up in cities. "The people who grew up in cities are kind of ‘walking time bombs' when facing the stress we meet today. However, people who have spent lots of time in nature since childhood are generally stronger in recovery and more positive." says Christopher Lowry, a professor of University of Colorado Boulder.
