【題目】The Angel of the North
The Angel of the North is a modern sculpture (雕塑) in Gateshead, Tyne and Wear, England, designed by Antony Gormley. Completed in 1998, it is a steel sculpture of an angel, 20 metres tall,with wings measuring 54 metres
across. The angel, like much of Gormley’s other work, is based on the shape of his own body.
According to the artist himself, the Angel of the North symbolises (象征著) the change from the industrial to the information age and stands proudly as a beacon (燈塔) of hope for the future of the region.
It cost 800,000 to make, with the money coming from the British government. It took four years to make the sculpture. It was made in three parts, the body, which weighed 100 tons, and two wings, which weighed 50 tons each. Angels are usually thought of being white, as they represent light, but Gormley’s Angel of the North is a reddish brown colour. This is because the steel has a special paint to protect it from strong wind.
The parts of the angel were moved from Hartlepool to Gateshead at night in big trucks. It took 5 hours to move everything, even though the journey is very short. The Angel of the North was put on the hill in Birtley on the 15th of February, 1998.
The sculpture was made in memory of the coal miners who worked hard in the dark earth below the hill to bring wealth to the North East in the 19th and 20th centuries. It is a sign for Gateshead.
The sculpture has since become one of the most famous landmarks in England as can be seen in television and film. It is the largest sculpture in Britain. Over 150,000 people come to Gateshead to see the sculpture every year.
【1】Who designed the Angel of the North?
【2】How long did it take to make the sculpture?
【3】What is the color of the Angel of the North?
【4】When was the Angel of the North put on the hill in Birtley?
【5】Why was the Angel of the North made?

【題目】Human, Don’t Come too Close
Frequent touching from humans may change plants’ genes and slow their growth. |
When we see babies or pets, we can’t help gently touching them to show our love. And they give us happy feelings back. But a recent study shows that it’s different for plants.
A study, published in The Plant Journal, shows that plants don’t “l(fā)ike” to be touched. That’s because touching changes their genes (基因) and, even worse, can slow their growth.
Professor Jim Whelan of the La Trobe Institute in Australia gave an explanation. “The lightest touch from a human, animal, insect, or even plants touching each other in the wind, leads to a huge gene change in the plant,” Science Daily reported.
In order to test the theory, the scientists did an experiment on plants. They grew a number of plants to the age of four weeks. Then they touched them with a paintbrush every 12 hours over a 36-hour period.
They found that as a response to the touch, the mitochondria (線粒體) in the plants had been partly destroyed. The mitochondria, as Science Alert noted, are the “powerhouse of the cell (細胞)”. The mitochondria produce energy for the rest of the cell in both animals and plants.
If this “powerhouse” is weakened, the plants will lose a large amount of energy that should have supported their growth. Whelan further explained to Science Daily, “If the touching is repeated, then plant growth is reduced by up to 30 percent.”
Although the process does have a strong effect on plants, usually the plants survive. Touching changes the plants, but it’s not necessarily a bad change.
According to Science Alert, frequent touching or moving plants will make them grow shorter than other ones. The researchers believe this change, in some way, could be helpful. It may help plants fight threats to their health such as insects and bad weather.
The new research findings have led to a deeper understanding of the plants’ response to touching. And the research might “open up new ways to reduce sensitivity (敏感性) and improve growth in the future”, Science Alert reported.
【1】Why did the scientists do the experiment?
A. To test if touching can change the genes of plants.
B. To show that plants’ and animals’ genes are different.
C. To tell when touching has effect on plants and animals.
D. To find out why some plants grow more slowly than others.
【2】What did the scientists find in their experiment?
A. Repeated touching shortened the plants’ life by four weeks.
B. Touching slowed down plant growth by reducing energy for growth.
C. Repeated touching made plants die sooner than they were expected to.
D. Mitochondria in the plants couldn’t produce energy because of touching.
【3】What do the scientists think of the fact that touch makes plants become shorter?
A. The plants will be more likely to be attracted by insects.
B. The plants will be more easily harmed by bad weather.
C. The plants will be less sensitive to being touched.
D. The plants will be better at fighting dangers.
