Many parents don’t know how much exercise their children need to do every day to stay     1     (health). The National Health Service guidance states that children     2     are aged from five to eighteen should do one hour of exercise every day, which about seventy percent of adults in the UK never mind. The research of 2,000 adults     3     (find) that only a quarter knew the exercise time recommended for young people.

The Youth Sport Trust leader, Ali Oliver said, “We have seen a drop in young people’s physical activity in recent     4     (year).” It is often     5     (report) that pupils are taken out of PE lessons to prepare for exams.

Meanwhile, figures from Sport England show only 17.5% of children are doing sports continuously. There is also a     6     (differ) among children from various economic (经济) backgrounds, with 39% of those from poor families doing     7     (little) than thirty minutes of exercise a day, compared with 26% from rich families.

This week thousands of people will get together     8     (celebrate) National School Sport Week, with     9    aim of promoting (推进) the importance of exercise and bringing great benefit     10     young people.

Recent studies have shown the benefit — even necessity — of     1     (spend) time outdoors, both for kids     2     adults. Some argue that it can be any outdoor environment. Some say it has to be a “green” environment — one with trees and leaves. Most of the studies agree that kids who play outside are     3     (happy) and less anxious ( 焦虑的) than kids who spend more time indoors. While it’s unclear how     4     (exact) the mood improvements happen, there are a few things we do know about why nature is good     5     kids’ minds.

There are various ways     6     (explore) outdoor environments, from the backyard to the park, and letting a child choose how he treats nature     7     (mean) he has the ability to control his own actions. This style of play also allows kids to interact ( 互动) meaningfully with their environments. They can think more freely, design their own activities, and approach the world in     8     (interest) ways.

Most ways of interacting with nature include more exercise than sitting on the sofa. Kids don’t have to join the local soccer team or ride a bike through the park — even a walk will get their blood pumping ( 流通). Not only is exercise beneficial to kids’ bodies, but it seems to make     9     (they) more focused, which is especially beneficial for kids with ADHD ( 多动症).

So while screen time is the easier, more popular choice,     10     is important to set enough time for outdoor play.

Teenagers sometimes turn to extreme methods to slim down quickly in a society where being thin is often seen     1     being beautiful. According to a recent survey of senior high school students’ lifestyles, almost one fifth of teenagers     2     (regular) skip meals, one in ten over-exercise and four per cent even take weight-loss medicine. Experts are concerned about     3     (them) health. They are increasing their efforts to educate teenagers about the side     4     (effect) of losing weight too quickly. They have also warned them       5       using such extreme methods, which are harmful.

It is normal for teenagers to be slightly overweight and there is no reason     6       they should be worried. However, for those who are dangerously overweight, it is very important that they try to lose weight properly.

Therefore, it is important to have a healthy     7     (balance) diet since teenagers are still growing and their bodies need a lot of nutrition       8     (function) well. What’s more, they should keep regular hours and get plenty of exercise to stay     9     (energy) and fit. We strongly encourage teenagers to follow these lifestyle tips, because living well is the     10     (safe) and most effective way to get into shape.

My dad is an enthusiastic (狂热的) runner who     1     (great) influenced me when I was young. So I was very sporty before the age of 14. However, when my family moved, my new school didn’t pay much attention     2     sports and had no after-school activities like football or running. Over the next few years, I     3     (stop) exercising apart from during Physical Education lessons at school. I looked like I was healthy; however, I was not.

One day, I was late for a bus, tried to run after it and in under a minute was out of breath! This made me realize how unfit I was.       4     (help) myself get in shape again, I made a(n)     5     (decide) that I would take up a kind of sport.

A friend of     6     (I) suggested a swimming pool close to my house     7     she goes to a few times a week. Now, I’m a swimming lover! I find swimming in the pool is very     8     (relax). I swim for     9     hour three times a week. I hope I will soon start to feel the benefits of regular exercise, and will become     10     (fit) than before.
