閱讀下面短文,根據(jù)小題的具體要求,簡要回答問題。

The north magnetic pole(磁極)is no longer a resident of Canada.It has drifted across the Canadian Arctic and is now angling toward Siberia.

Not to be confused with the geographic North Pole—the northern extremity of the Earth’s axis(地軸),the north magnetic pole(where the Earth’s magnetic field is directed downward)is moving due to natural changes in the Earth’s magnetic field,a process that originates about 3000 kilometers below our feet,in the outer core(核心)of the planet.But scientists are now noticing that the magnetic pole has picked up its pace.

Over the past century,the pole has been migrating at an average speed of about 10 kilometers per year,says Larry Newitt,head of Geomagnetic Laboratory at Natural Resources Canada in Ottawa.Since the 1970s,this speed has increased to about 50 kilometers per year.

Scientists are wondering why the speed is increasing,says Newitt.One hypothesis(假說)relates it to “magnetic jerks”,sudden shifts(變化)in the rate of change of the magnetic field.There have been three jerks in the past four decades,each one correlating to an increases in speed.

If the north magnetic pole continues at its current rate,it could reach Siberia by 2056.

“For most of recorded history,the pole has been a part of Canada,and now it’s not,”says Newitt.“It may be a blow to our collective psyche,but other than that,it doesn’t have a major effect on most people’s existence.”

1.Find in the passage a word closest in meaning to the underlined word “angling”.

In July, 1916, Gaynor was a nine-year-old girl and lived in North Wales. One day, on her way home from school, she saw a silver object in a field not far from her home. The object looked like a saucer. Gaynor was very scared. She stayed in the tall grass and watched the door of the strange object open. She saw two aliens wearing silver suits get ou. Then they use something to examine the ground. They were short and had pink eyes. After about half an hour, the two aliens went back into the object. Then it took off. When Gaynor got home, she told her mother about her unusual experience, but her family decided to keep quiet about it. They didn’t want others to laugh at their daughter. However, 18 months later, Gaynor told her story to UFO scientists. They found out that Gaynor told the truth.

閱讀下面短文,根據(jù)小題的具體要求,簡要回答問題。
Their round bodies, round flat noses and large ears often remind us of bears every time we see koalas. Probably that’s why these animals are often referred to as koala bears. Koalas are natives of Australia. However, they aren’t found all over the continent. The habitat of koala bears  is eastern regions of Australia and South Australia.
Koalas are found where there are enough forests of eucalyptus(桉樹) trees. The association of koalas and eucalyptus trees is due to the fact that these animals feed on the leaves of eucalyptus trees. But that’s not all. In addition, the trees also serve as the homes of the koalas.
Koalas grow around 27 to 36 inches tall and weigh 5 to 9 kilograms on average. Male kaolas are larger than the females. Life can stretch up to 17 years.
Like many other animals, the habitat of koala bears is fast decreasing due to deforestation and quick urbanization(都市化). However, efforts by some scientists and animal lovers have successfully introduced these creatures back in certain parts of Australia.

A woman saw three old men with long white beards sitting in her front yard. She said, ‘I don't think I know you, but you must be hungry. Please come in and have something to eat.’ ‘We do not go into a House together,’ they replied. ‘Why is that?’ she asked.

One of the old men explained, ‘His name is Wealth,’ he said pointing to one of his friends, ‘a(chǎn)nd he is Success, and I am Love.’ Then he added, ‘Now go in and discuss with your husband which one of us you want in your home.’

The woman went in and told her husband what the old man said. Her husband was excited. ‘How nice!’ he said. ‘Since is the case, let us invite Wealth. Let him come and fill our home with wealth!’ His wife disagreed. ‘My dear, why don't we invite Success?’ Their daughter was listening from the other corner of the house. She jumped in with her own suggestion, ‘Wouldn't it be better to invite Love? Our home will then be full of love.’ The husband said to his wife, ‘Go out and invite Love to be our guest.’

The woman went out and asked the three old men, ‘Which one of you is Love? Please come in and be our guest.’ Love got up and started walking towards the house. The other two also got up and followed him, the lady asked Wealth and Success, ‘I only invited Love, ­why are you coming in?’

The old men replied together, ‘If you had invited Wealth or Success, the other two of us would have stayed out, but since you invited Love, wherever he goes, we go with him. Wherever there is Love, there is also Wealth and Success!’
