Delicate Arch
Delicate Arch can be found in Arches National Park in Utah, USA. The arch stands alone at a height of 52 feet and is considered one of Utah’s most important landmarks. In 2002, the Olympic torch passed through this arch to mark the beginning of the winter games.
Wave Rock
This 15-meter high and 110-meter long impressive natural rock formation is located in Western Australia. It looks like a large, smooth wave ready to break. Algae(海藻) grow on the surface of Wave Rock.
The Wave
The Wave is located on the slopes of the Coyote Buttes, Arizona, USA. This incredible formation can be reached by hiking approximately 4.8 kilometers, making the round trip to and from The Wave a nearly 9.7-kilometer hike that climbs about 107 meters in altitude.
James Bond Island
James Bond Island can be found in Aohang-Nga National Park in Thailand. The needle-shaped rock formation was named James Bond Island because it was featured in a 1974 Bond film The Man with the Golden Gun.
Devil’s Tower
The formation known as Devil’s Tower can be found in Wyoming, USA. Also known as Bear Tower, the rock formation is actually the neck of a volcano. It rises 386 meters above the surrounding land and the top of it is 1.558 meters above sea level.
The Giant’s Causeway
The Giant’s Causeway is located in Northern Ireland and has a series of over 40,000 columns made of basalt(玄武岩). Each column is connected and the formation is believed to be a result of volcanic ash. Believe it or not, when this formation was first discovered, scientists argued as to how it was formed. Some thought it was natural, others thought it was manmade, and some thought that perhaps it had been created by a giant!
Bryce Canyon National Park
One of the most impressive rock formations in the world is the Bryce Canyon in Utah, USA. It is a national park and despite its name, it is not actually a canyon, but rather a giant natural amphitheater(圆形竞技场) created by erosion.

名题训练系列答案If we observe carefully, we van find that most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in million. People have made a census(普查)to colours of more than four thousand kinds of flowers and discovered that only eight of them are black. Why?
As we know, sunlight is formed by seven different kinds of coloured light. The wave length of each light changes, so the quantity of heat in each light changes, too. Flowers, especially their petals(花瓣), are very delicate(纤弱) and prone(易于) to the harm caused by high temperature. Black flowers can take in all the light waves, which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat.
That is why red, orange and yellow flowers are very common in nature while black flowers are so rare.
【小题1】We can hardly find black flowers because _____.
| A．they are so weak that it’s difficult for them to grow up |
| B．there are no black flowers in the world. |
| C．the petals of black flowers are very delicate |
| D．they can take in the light of all wave lengths, which make the flowers dry up |
| A．many different kinds of coloured light |
| B．three different kinds of coloured light—red, orange and yellow |
| C．seven different kinds of coloured light |
| D．four thousand kinds of coloured light |
| A．less heat than the other lights | B．more heat than the other lights |
| C．a great deal of heat | D．a little heat |
| A．it is common | B．it is extremely rare | C．it’s lucky | D．it’s impossible |
You’re sitting on the train home and the person opposite you yawns(打哈欠). Suddenly, you’re yawning with him, though you’re not tired.
This phenomenon confused scientists for years until a recent study found that people tend to sympathize with fellow humans. Supporting this claim was the discovery that those children who were unable to form normal emotional ties with others did not experience contagious(有感染力的) yawning, which showed that humans communicate regularly with out words.
Hugo Critchley, a neuroscientist, has conducted an experiment recently, which will prove that happiness and sadness can spread like the common cold. According to Critechley, our mind and body are in constant exchange about how we’re feeling. “Emotions are closely linked with states of internal(内部的) responses,” he explained. “ There are also more visible changes in our gestures and facial expression. When we’re in a group, these signals can spread to another person. For example, there’s the obvious tendency to smile when smiled at and there are less obvious changes that reflect emotions of surprise, anger or sadness such as a change in our heart rate and blood pressure.
Hugo Critchley further explained, “Our bodies synchronies and when we like the other person, we ever copy his behavior. Next time you chat with a friend, take note of how you’re sitting— it’s pretty likely that you will be the same. Scientists believe it’s our way of telling each other that we’re partners. Through body language, humans give each other very subtle(微妙的) but clear signals that show emotions.”
So, what lessons can we learn from this? “ Spend time with happy people— otherwise your health could suffer,” said Critchley.” When we’re sad, our body goes into fight or flight mode. But when we’re happy, our body works normally and we feel relaxed and positive. So we look bright, our skin glows, we feel healthy and it affects everyone around us.”
