All parents know that one of their most important tasks is to prepare their children for an independent life, but any parent can tell you that it’s hard to let go of your children. That balance between keeping your children safe and allowing them to learn from their own mistakes can be heartbreaking. Years of experience means that parents often do know best, but on the other hand the young, being less bound by tradition, are often more creative, more able to find new solutions to old problems. Revolutions are led by the young.

Good teachers make the growth of critical thinking (批判性思维) easier in their students, only to find that this lead to a questioning of the teachers’ basic beliefs. Schools encourage parents to become involved, but are often embarrassed when parents have doubts about some of the educational methods being used. Governments encourage unimportant groups to empower themselves in order to participate fully in the development process. And they are often surprised when the new leaders of these groups turn around and attack the policies or decisions of that same government. However, the rebellious (叛逆的) young and the newly unimportant groups are important in social development. They are not necessarily representatives of those they want to represent in their demands, but their voices must be heard.

Good parents know that just forbidding (禁止) particular behaviors does not prevent their children from finding ways to engage in these forbidden activities. Indeed, sometimes the forbidden fruit is more inviting, just because it is not accepted by authority. Parents must work with their children to educate them on the facts, know as much as possible about the lives of their children, provide a good example, encourage more wholesome activities but also support their children when they don’t follow what is expected of them. But the most important point is that they also need to learn how to let go.

Honey from the African forest is not only a kind of natural sugar, it is also delicious. Most people and many animals like eating it. However, the only way for them to get that honey is to find a wild bees’ nest and take the honey from it. Often, these nests(巢) are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper—a little bird called a honey guide.

The honey guide does not actually like honey, but it does like the wax(蜂蜡) in the beehives(蜂房). The little bird cannot reach this wax, which is deep inside the bees’ nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax, always falls to the ground, and this is when the honey guide takes its share.

Scientists do not know why the honey guide likes eating the wax, but it is very determined in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.

A breathtaking trick potentially left over from our ancestors might be found in us — the ability to sense oxygen through our skin.

Amphibians, animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo.

Now the same oxygen sensors found in frog skins and in the lungs of mammals (哺乳动物) have unexpectedly been discovered in the skin of mice.

“No one had ever looked,” explained Randall Johnson, a biologist researcher.

Mice and frogs are quite distant relatives, so the fact they have these molecules (分子) in common in their skin suggests they might well be found in the skin of other mammals, such as humans.

“We have no reason to think that they are not in the skin of people too,” Johnson said.

These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen—a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1a genetically removed from their skin failed to produce this hormone (荷尔蒙) even after hours of such low oxygen.

These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia (贫血症) without injecting drugs, which make up a multibillion-dollar market, Johnson said.

Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. “It’s hard to say what exactly might be done, however—there’s a lot we don’t know yet,” Johnson explained.

The scientists detailed their findings in the April 18 issue of the journal Cell.

1.Which of the following statements is TRUE according to the passage?

A．It has long been expected oxygen sensors exist in mice’s skin.

B．People have to surf the Internet to read detailed findings.

C．It has been proved that these findings help treat lung diseases.

D．Johnson believes that Oxygen sensors also exist in human skin.

2.One of the functions of the molecules mentioned above is _______.

A． increasing level of oxygen                B．improving athletes’ performance

C．detecting oxygen                       D．carrying oxygen around the body

3.What is Johnson’s attitude to the application of the findings to the athletes’ training?

A． Hesitating        B．Doubting          C．Positive           D．Negative

4.The best title of the passage may be _______.

The iPhone, the iPad: each of Apple’s products sounds cool and has become a fad (一度时髦的风尚). Apple has cleverly taken advantage of the power of the letter “i” — and many other brands are following suit. The BBC’s iPlayer — which allows Web users to watch TV programs on the Internet — adopted the title in 2008. A lovely bear — popular in the US and the UK — that plays music and video is called “iTeddy”. A slimmed-down version of The Independent newspaper was launched last week under the name “i”.

In general, single-letter prefixes have been popular since the 1990s, when terms such as e-mail and e-commerce first came into use.

Most “i” products are aimed at young people and considering the major readers of The Independent’s “i”, it’s no surprise that they’ve selected this fashionable name.

But it’s hard to see what’s so special about the letter “i”. Why not use “a”, “b”, or “c” instead? According to Tony Thorne, former head of the Language Center at King’s College London, “i” works because its meaning has become ambiguous. When Apple uses “i”, no one knows whether it means Internet, information, individual or interactive, Thorne told BBCMagazines. “Even when Apple created the iPod, it seems it didn’t have one clear definition,” he says.

“However, thanks to Apple, the term is now associated with portability (轻便).” Adds Thorne.

Clearly the letter “i” also agrees with the idea that the Western world is centered on the individual. Each person believes they have their own needs, and we love personalized products for this reason.

Along with “Google” and “blog”, readers of BBCMagazines voted “i” as one of the top 20 words that have come to define the last decade.

But as history shows, people grow tired of fads. From the 1900s to 1990s, products with “2000” in their names became fashionable as the year was associated with all things advanced and modern. However, as we entered the new century, the trend unavoidably disappeared.

2.We can infer that The Independent’s “i” is aimed at _________.

A．engineers         B．old readers        C．fashionable women  D． young readers

3.Nowadays, the “i” term often reminds people of the products which are _________.

A．environmentally friendly                  B．easy to carry       C．advanced  D．recyclable

4.The writer suggests that _________.

A．“i” products are often of high quality

B．iTeddy is a living bear

C．the popularity of “i” products may not last long

D．the letter “b” replaces the letter “i” to name the products
