Hey girls, if the boys in your class are acting silly, you might as well leave them alone. You are far more sensible than them, aren’t you?
There is science to back up this theory. Scientists from Newcastle University, UK, and Seoul University, South Korea, found that the brain matures (成熟) earlier in girls than in boys. This is partly because of the way children’s brains are “pruned.”
As the brain matures, it begins to cut out unimportant information and focus on important information. This process is called “pruning.”
In order to learn more about this process, scientists scanned the brains of 121 people aged between 4 and 40. They found that pruning began much earlier in girls. Between the ages of 10 and 12, a girl’s brain will start to see a lot of activities as the pruning process starts. But for boys, this doesn’t start until the age of 15 to 20.
During this process, the brain will turn off memories, sounds or sights that appear several times. But important connections, like linking the sound of a familiar person’s voice to their face, are kept.
“The loss of connectivity during brain development can help to improve brain function,” scientist Sol Lim told the Daily Telegraph.
To understand this more easily, imagine you are at a party and everyone is talking. You can’t concentrate. But if you “turn off” some of the voices, it is easier to hear the others. The brain works in a similar way.
1.What did the scientists find?
A. Boys usually focus on unimportant information.
B. Girls never focus on unimportant information.
C. Girls mature earlier than boys.
D. Connectivity helps improve brain function.
2.What does the underlined word “pruned”probably mean?
A. 删减 B. 成长 C. 改变 D. 损失
3.What happens during the process “pruning”?
A. The brain doesn’t work for a moment.
B. You can’t remember, hear or see.
C. The connections between things disappear.
D. Brains develop to focus on important information.
4.What can we know from the passage?
A. Boys are more silly than girls.
B. Boys are less sensible than girls.
C. You can never concentrate at the parties.
D. Brains function better after losing some connections.

A long walk in the desert or the mountains can be exciting. And it’s a great way to keep fit. If you carry a tent and some food, you can camp overnight. But wild places can be dangerous. Here’s how you can enjoy walking and camping safely.
Before your trip
☆ Tell someone where you are going and when you expect to return. If you don’t return on time, the people at home will know that you are lost or in trouble. They will know where to look for you.
☆ Make sure you’ve got a good map of the area that you’re going to.
☆ Make sure you’ve packed the right equipment for your activities. The desert is often hot, but nights can be very cold, and sometimes there are big rainstorms. In the mountains, the weather can change suddenly. A sunny day can turn cold and cloudy quickly.
The tools for survival(生存)
Sunglasses, sun hat, sun cream, windproof jacket, good walking shoes or boots, food, water, maps, compass, first-aid kit, matches, rope, knife, ground sheet,
the pack to carry your equipment.
What to do if you get lost
☆ If you’re in a car and it has broken down, stay with your car.
☆ If you are not traveling by car, make yourself easy to see. A signal fire can be seen at night. During the day, smoke may be used to show where you are. A brightly-colored blanket(毯子) may help rescuers to find you.
☆ Stay where you are.
☆ If you walk for any reason, avoid walking during the hottest part of the day. Morning and evening walking is better for saving your energy water.

You can easily find that your sister or brother is different from you. You live together in the same house and have the same parents, but you have different personalities(性格).
Why? One possible reason is the way your parents treat you.
Firstborn children receive all the attention from their parents. Generally speaking, a firstborn has twice as many photos as any other child has. Parents usually give firstborns more responsibilities (责任)and depend on them to take care of younger brothers and sisters. As a result, firstborns are often responsible, hard-working, and serious. They often want to do well at school and in work. More firstborns became American Presidents, for example George W.Bush, George Washington and Lyndon Baines Johnson, than second or last-borns.
When a second child arrives, parents are more relaxed. The second child has to compete (竞争)with the first-born for parents’ attention and love. These children often choose different sports and hobbies to develop different personalities. They are often outgoing, but can be jealous and get angry easily.
The youngest child is usually the happiest, and has fewer responsibilities and more freedom(自由的). These children do well at school and in work, but have to be creative（创造性的） to get their family’s attention. They are often friendly and cool. Many famous talk-show hosts were born last.
