Statistically, air travel is by far the safest way to travel, and you can make flying even safer, just by following these simple rules．As your chances of being involved in an air accident are practically nil(零), many of these tips concern what you should and shouldn’t do to make your journey safer when you are airborne(升空的)．
Fly on non-stop routes
Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures．
Choose larger aircraft．
Although small aircraft have very good safety records, those with more than 30 passenger seats are designed to comply(遵守)with much stricter regulations and are tested more regularly to make sure they still comply. Also, in the unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival．
Pay attention to the pre-flight safety briefing
The information may seem repetitious(重复的), but it’s worth listening to the flight attendants．And even if you’ve flown before, it doesn’t mean you know everything about the aircraft you’re on, such as the location of the closest emergency exit．
Store things safely
Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence(气流)．
Keep our seat belt fastened while you are seated
Cabin crew always tell you this, but it’s important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to．The general rule of flying is this: If you are told to do something, do it first and ask questions later.
Let the flight attendant pour your hot drinks
Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them.

Strange stones of Costa Rica
One of the strangest mysteries in archacology was discovered in the Diquis River Delta, in southern Costa Rica. Since the 1930s, hundreds of stone balls have been found. They range in size from a few centimeters to over two metres in diameter.
Who made these perfect spheres(球体) and how they made them remains a mystery. Some researchers believe the stones were made by extreme heating followed by cooling. People could have polished the spheres with sand or leather. The ancient Costa Ricans had no written language so there is no written record of just how they made the spheres.
Almost all are made of granite (花岗岩), a hard stone created by volcanoes. The granite quarries(采石场) were 25 to 30 miles away from the largest stones, which weigh more than 10 tons each. Nobody knows how people moved them..
Many of the stones have been found near the remains of houses or graves. Some believed that the stones contained hidden treasures and a few have been smashed but nothing has been found inside. Despite these losses, the National Museum of Costa Rica has recorded 130 spheres. However, many stones are not included because they have been removed from their original sites and used as ornaments(装饰) in homes, gardens and churches.

Computers are very important to modern life. Many people think that in the future computers will be used in lots of everyday life. It is thought that we won’t have to go shopping because we will be able to get most things which are sold in shops on the Internet.

Homework can put you in a bad mood, but that might actually be a good thing.New research suggests that, in some cases, being too happy can hurt your performance on certain kinds of tasks.To test whether it is true, researchers performed two learning experiments with children.
The first experiment included 30 children, aged 10 and 11.Each child was given 20 problems in which a houselike shape was hidden inside a different, larger image.The children had to find the small shape while sitting in a room.Either positive or sad classical music was played in the background.
As a measure of mood,the scientists asked the children to point to ont of five faces,ranging from happy to sad.Children listening to the positive music tended to point to the smiling faces.Children surrounded by sad music pointed instead to the frowns(皱眉).The researchers found that sad children took at least to find the small shapes and also correctly found on average three or four more shapes.
In the second experiment,61 children,aged 6 and 7,faced the same type of problems.They watched one of three scenes.One scene was happy.One was neutral(中立的).One was sad.And just like in the first experiment; kids who felt sad or neutral performed better on the tests.They solved on average two or three more problems.
The researchers think that feeling down causes people more likely to fix their attention on a problem or difficult situation.However, other studies suggest that people who feel happy are better able to fix their attention on details.Some researchers insist that the new studies have flaws.It’s possible that the lively music in the first experiment took children’s attention away from their task of finding shapes.
While scientists continue to work on finding the answers,it will might be worth adapting your tasks for your mood.What did the researchers want to find out the experiments?
| A．What determines success in children’s study |
| B．How to train children to keep a happy mood |
| C．Whether and how children’s moods affect their performance |
| D．Whether too much homework affects children’s moods |
What did the two experiments have in common?
| A．Children were divided into happy and sad groups |
| B．Children were asked to find hidden shapes |
| C．Children in a sad moon were considered much cleverer |
| D．Researchers used music to measure children’s moods |
Through the two experiments, researchers think that sadness cause people to___.
| A．perform better in some cases |
| B．become cleverer than before |
| C．pay more attention to details |
| D．be more likely to be influenced by music |
