Bones are hard on the outside (外面), but they are soft (软的) on the inside (里面). The soft part of the bone makes our blood (血). We need things through our bodies. Blood can carry these things. It also helps move away useless (无用的) things for our bodies, so we can stay healthy.

Calcium (钙) makes our bones harder. We need to get enough of it each day. We can get calcium easily from milk, some vegetables and other foods.

Vitamin (维生素) D is also important because it helps calcium work well in our bodies. We can get vitamin D from food like fish and eggs, and we can also get it from the sun. Try to get a little sun every day, and you can have healthier bones!

Exercise can make our bones healthy, too. Running, jumping and dancing are all good exercise, even everyday activities, like walking and climbing mountains can help keep our bones healthy and strong, too.

【推荐1】In 1939 two brothers, Mac and Dick McDonald, started a drive-in restaurant in San Bernadino, California. They carefully chose a busy corner for their location. They had run their own businesses for years, first a theater, then a barbecue(烤肉) restaurant, then another drive-in. But in their new operation, they offered a new, shortened menu: French fries, hamburgers, and sodas. To this small selection they added one new idea: quick service, no waiters or waitresses, and no tips.

Their hamburgers sold for fifteen cents. Cheese was another four cents. Their French fries and hamburgers had a remarkable uniformity(一致性), for the brothers had developed a strict routine(程序) for the preparation of their food, and they insisted on their cooks’ sticking to their routine. Their new drive-in became surprisingly popular, particularly for lunch. People drove up by the hundreds during the busy noontime. The self-service restaurant was so popular that the brothers had allowed ten copies of their restaurant to be opened. They were satisfied with this modest success until they met Ray Kroc.

Kroc was a salesman who met the McDonald brothers in 1954, when he was selling milkshake-mixing machines. He quickly saw the special attraction of the brothers’ fast-food restaurants and bought the right to franchise(特许经营) other copies of their restaurants. The agreement struck included the right to duplicate(复制) the menu, the equipment, even their red and white buildings with the golden arches(拱门).

Today McDonald’s is really a household name. In 1976, McDonald’s had over $1 billion in total sales. Its first twenty-two years in one of the most surprising success stories in modern American business history.

The British are well known for the amount of tea that they drink. Each person in the UK drinks around 1.9 kg of tea every year. That’s around 876 cups of tea. Tea is drunk by the whole society. But tea doesn’t grow in Britain. Most of the tea is grown in India and China. So how did it become an important part of British culture?

Tea arrived in London in the 1600s. At this time British ships were exploring（探索）the world and found the drink by accident in China. It was not long before green tea was available to buy. However, this was only available to the rich.

At the beginning of the 1700s, the amount of tea arriving in Britain increased gradually. Black tea arrived at this time. At first, people drank this tea exactly as it was in China. They soon discovered that it tasted good with a little milk and sugar, giving the drink a special British characteristic which can be seen as one of the symbols of Britain.

In the 1800s, tea was still a product enjoyed only by people with money. At this time they began to have “afternoon tea”. This means drinking tea with snacks around 4 pm to avoid feeling hungry between lunch and dinner. It is a tradition that is still going today but has become less popular in recent times.

In the late 1800s, the price of the tea dropped fast as more tea began to arrive on ships from India and China. It was no longer a drink just for rich people. Tearooms—shops where you could buy and drink tea—started to appear across the country. People enjoyed drinking tea and socializing（社交）in these places. At the start of the 20th century, the British began to make tea in their homes whenever they felt like it. Teapots became a must in every kitchen.

【推荐1】We have found plastic in the ocean and in animals like birds, fish and whales. But for the first time, scientists have found plastic in the waste from the human body, USA Today reported.

The findings came from a pilot study led by scientists from Environment Agency Austria. The researchers followed eight healthy volunteers from different parts of the world. The volunteers wrote down what they ate for a week and then provided a stool sample for testing.

Scientists found nine different types of plastic in the samples, according to the study. An average (平均数) of 20 small plastic particles (颗粒) were found in every 10 grams (克) of stool. The particles measured between 50 to 500 micrometers.

“The smallest plastic particles can enter the bloodstream, the lymphatic (淋巴的) system, and may even reach the liver (肝脏),” Philipp Schwab, who took part in the research, said to The Guardian.

However, the scientists aren’t sure if the plastic is harmful to humans. They’re not sure how the plastic got in the volunteers’ bodies, either. But most of the volunteers said they drank from plastic bottles and also ate seafood that could include plastic from ocean pollution.

In fact, plastic is everywhere around us. Every year, an average of 8 million tons of plastic waste goes into the oceans, according to National Geographic. There, sunlight and waves break the plastic items down to the sizes of grains (谷物) of rice. Most of the particles stay in the ocean; others can spread into the soil and the air. Could plastic in the air fall onto food and get into the human body?

According to USA Today, 90 percent of sea salt sold globally contains plastic. And even some tap water has been found to have tiny plastic particles in it.
