On Saturday my Catalan friend invited me to come along to a Calotada. Being from the UK, I had no idea what this would need, but he promised me it was a fun Catalan(卡塔兰)tradition, and so I agreed to go. I wasn’t disappointed!

First, we took a train out to a small town near Tarragona, about an hour away from Barcelona centre. I was already amazed by how different everything looked from the city as the train rushed through small towns, all sitting on the coastline.

When we arrived, we were greeted by the sight of a small wind instrument band and about a dozen people dancing in a circle. While my friend later told me that it is a traditional Catalan dance called La Sardana, at the time I was totally confused at what I was seeing! It seemed so strange but yet so lovely that they were doing this dance completely for themselves.

Once we had been fully entertained by the dancers, we finally went inside for the Calotada and it was soon revealed to me what it actually was. We sat down at the table and a huge plate of leeks(大葱)was placed in front of us. It was explained to us that you have to peel the leeks with your fingers, dip them in a (delicious!) sauce and eat them. This sounds easier than it was.

My friend had been right in the end, it had been an extremely fun day and it felt great to get involved in a local tradition of a place I am temporarily calling home. It really inspired me to learn more about the Catalan culture, although hopefully next time it will be something less messy!

Light travels（传播）at a speed which is about a million times faster than the speed of sound.In one second,light travels about 300,000 km,but sound travels only 344m.You can get some idea of this difference by watching the start of a race（比赛）.If you stand some distance away from the starter,you can see smoke come from his gun before the sound reaches your ears.This great speed of light produces（产生）some strange facts.Sunlight takes about 8 minutes to reach us.If you look at the light of the moon tonight,remember that the light rays（光线）left the moon 1.3 seconds

before they reached you.

The nearest star is so far away that the light which you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km per minute.In some cases（在某种情况下）the light from one of tonight's stars started on its journey to you before you were born.

Here's a new warning from health experts：sitting is deadly. Scientists are increasingly warning that sitting for long periods, even if you exercise regularly, could be bad for your health. And it doesn't matter where the sitting takes place—in the office, at school, in the car or before a computer or TV. Just the overall number of hours it takes counts. Several studies suggest people who spend most of their days sitting are more likely to be fat, have a heart attack or even die.

While health officials have issued (发布) guidelines advising on the least amounts of physical activity, they haven't suggested people try to limit how much time they spend in a seated position.

“After four hours of sitting, the body starts to send harmful signals，” said Ekblom?Bak of the Swedish School of Sport and Health Sciences. She explained that genes controlling the amount of glucose (葡萄糖) and fat in the body start to shut down.

Even for people who exercise, spending long periods of time sitting at a desk is still harmful. Tim Armstrong, a physical activity expert at the World Health Organization, said people who exercise every day but still spend a lot of time sitting might get more benefits if that exercise were spread across the day, rather than in a single hour.

Still in a study that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat more had a higher death risk, whether they exercised or not.

Experts said more research is needed to figure out just how much sitting is dangerous, and what might be possible to offset those effects.

“People should keep exercising because that has a lot of benefits，” Ekblom?Bak said. “And when they're in the office, they should try to interrupt sitting as often as possible. ”

1.The underlined word “offset” in Paragraph 6 most probably means “________”．

A. turn to B. work out

C. get rid of D. make use of

2.Sitting too much is dangerous because it can ______.

A. make a person unable to exercise enough in a day

B. destroy the balance of glucose and fat the body

C. increase glucose and fat in the body

D. make a person become lazy

3.In the opinion of Ekblom?Bak, when at work, you'd better have a rest by ________.

A. sending your friends e?mails

B. taking a walk around your office

C. chatting online or playing computer games

D. listening to music while sitting

4.Which of the following might be the best title for the passage?

A. Side Effects of Sitting Too Much

B. Don't Sit Too Much While Working

C. More and More People Sit Too Much

D. Sitting Too Much Could Be Dangerous

A new set of R's are here: Recycle, Reduce and Reuse. These three “Rs”，when used every day, can reduce the amount of waste going into landfills, reduce the litter polluting the land and water, conserve (节约) energy and save your money.

Recycling is one of the easiest ways to save energy, money and time while reducing the amount of garbage going into landfills.

Most communities have roadside pick?up service to recycle common household items like glass, steel, aluminum, newspaper and cardboard. By separating out the recyclable items from normal household trash, you can reduce the amount of trash entering a landfill by more than 75 percent.

Recycling one aluminum beverage can saves enough energy to run your television for three hours. Even better, local recyclers or scrap?metal dealers may pay money for your metal recyclables.

It is estimated that the 54 billion cans recycled last year in the US saved 15 million barrels of oil. That is equivalent (相等的) to the US oil consumption for one day. Recycling other household items offers similar savings in money and energy.

Composting food waste will reduce your trash load even more. A basic compost pile built with the help of instructions from numerous resources on the web can be constructed over a weekend, using materials easily obtained from local hardware or home improvement stores. In addition to reducing your waste, this all?natural recycling provides safe, clean and organic fertilizer for your garden, eliminating the need to buy chemical?derived products.

Finally, recycling other household items like computers, televisions and monitors and household chemicals like pesticides (农药) and paints will remove dangerous chemicals like mercury (水银) and lead from the landfills.

If your community doesn't offer recycling programs, contact your local government to get one established.

1.What's NOT true about recycling in the eyes of the author?

A. It's energy?efficient.

B. It's money?saving.

C. It's time?consuming.

D. It's environmentally?friendly.

2.Recycling________aluminum beverage cans save enough energy to keep your TV on for half a day.
