On May 9, James Givens was sitting in the car when he heard what     1     (sound) like a knock. He turned around only     2     (find) a goose pecking at the car door, which was highly unusual seen. He knew that the birds     3     (normal) preferred to observe humans from a distance.

But on this day, the goose appeared to be determined to get his attention and did not stop pecking     4     Givens opened the car door and stepped out. Although     5     (force) to walk away a little out of fear, the bird kept turning around to make sure that he was following. When they finally stopped, Givens realized     6     the mother goose did so — she needed help to free her baby goose that had got     7     (trap) in some balloon string.

Worried that the mother goose would attack him if he got close     8     the baby, Civens called the local chapter of Society for the Prevention of Cruelty to Animals. Unfortunately, they were unable to help right away. Mainly     9     (take) into consideration that the baby goose would not survive the delay, Givens decided to take on the task himself.

The mother goose watched patiently as Givens saved the little bird. As soon as the little goose was free, it ran to its mom. Givens said this was the most     10     (forget) incident in his life!

Lots of cats love having cat companions, but if     1     (you) doesn't, it might act out by showing fear or aggression.

This doesn't     2     (necessary) mean you have to give one up! ”Cats show great     3     (flexible) in their social behavior," says Kristyn Vitale, a researcher at the Human-Animal Interaction Lab at Oregon State University, US.

She suggests     4     (separate) the cats into different areas of the house and slowly reintroducing them to one another by using a method that     5     (call) “Scent(气味)，Sight. Touch"： Take a toy or blanket from each cat and exchange them. Give each cat the other cat's scent item along with lots of praise and rewards so they associate the smell with good things. After doing this several times, set up a space in     6     the cats will be able to see one another through a physical barrier, like a screen door     7     a gate. Then feed them, so they start to associate positive feelings with the sight of the other cats. After a few successful feeding     8     (session), you can try to introduce the cats     9     a barrier. You can distract each cat with toys during their first meeting in the same room, so they have less time     10     (worry). “If owners go slow and give lots of rewards, many cats can learn to accept a companion cat." Vitale says.

Of all the events in the universe, solar eclipses may lead to the     1    (great) change in animal behavior.    2    (puzzle) animals that are active during the day head back to their night places while night animals think they've overslept.

When the sun, moon and the earth are     3     a straight line, there will be an eclipse, so that the moon completely     4    (block) the sun. Around the world, when a solar eclipse occurs, unusual phenomena in animals are often reported.

Some spiders start breaking     5    (they) nets during the eclipse, just as they usually do at the end of the day. Once the solar eclipse has passed, they will start to rebuild them.     6    (similar) , fish and birds,     7     are active during the day, go to their night resting places while bats come out. They seem to be tricked by     8     sudden darkness.

Once it     9    (observe) that hippos in Zimbabwe left their rivers during an eclipse, and headed towards their night     10    (feed) places on dry land. In the middle of their journey, the solar eclipse passed, daylight returned, and the hippos gave up their efforts.

Tianjin is an important stop on one of the eight major bird-migration routes     1     North Asia to Australia, and many species rest in Beidagang’s coastal area before flying to Australia or New Zealand. The birds will return to Tianjin on their northward migrations that go as far     2     the North Pole. Beidagang Wetland     3    (cover) nearly 350 square kilometers, including an area of about 115 sq km, in the southeast of the Binhai New Area. The wetland is essential for the birds’ breeding and growth. “Without it, they may be in danger during their migrations,” experts say.

Beidagang Wetland Management Center deputy director Sun Baonian says they’ve made great efforts to improve rare — bird protection in recent years.     4     total of 1,347 Oriental storks have been identified in the wetlands,     5    (account) for nearly 45 percent of I he species’     6     (globe) migration population, he says. They prefer to nest in high trees and buildings. Since Beidagang doesn't have enough high trees, the center has set up 20 artificial nesting areas on poles, 13 of     7     have been used by the waterfowl (水禽). And 17 chicks were born in the wetlands late last year.

The center also offers “homes” for volunteers and tourists, who come to learn more about wetland protection and enhance their     8    (aware) about how to protect the wetlands and birds.

The project     9    (support) by the International Union for Conservation of Nature since 2012, following a high-level meeting in South Korea. In 2016, the IUCN encouraged China     10    (apply) for UNESCO status for the sites.

My Mind-Shifting Qomolangma Swim

Lewis Pugh is a famous swimmer, who swam across the North Pole in 2007. The water there was so cold his fingers were    1    (freeze). Why did Pugh do this? Well, he wants people    2    (pay) attention to global warming.

As a boy, Lewis visited national parks and he learned how fragile and    3    (amaze) the Earth is. Now he    4    (intend) to protect the Earth. He decided to swim in water near the North Pole to bring attention to the melting glaciers. Lewis said that the swim was so painful that    5    would be his last time swimming in freezing water.    6    when he heard about Lake Imja, near Mt. Qomolangma, high in the Himalayas, he decided to swim in cold water again.

Mt. Qomolangma is the    7    (tall) mountain in the world and swimming there is very difficult. Because of global warming, glaciers on Mt. Qonolangma are melting and leaving lake behind,    8    Lake Imja.

Lewis says he learned two    9    (lesson) from swimming at Mount Qomolangma. First, he learned that people can unintentionally do a lot of damage. We do things which hunt the Earth because we know no other way to live. Second, We can all do    10    we can to protect our environment if we change the way we think and think more about our future.

While thousands of college students headed for warm climate to enjoy sun and fun during their week off from classes, seven local students had other plans.

The Northern Essex Community College (NECC) students and one of their teachers spent part of their spring break in New York City, helping repair an area     1     (destroy) by the hurricane. “I wanted to see for myself what happened,” said Terry. “I couldn’t imagine    2    it is like to lose your home and everything that you know and the    3    (power) effect the hurricane had on those people. I wanted to do something, to understand their feeling of helplessness.” The group headed into Brooklyn’s Red Hook district, which was hit hard by the hurricane. There they met people from other parts of the country,     4    had also volunteered to help. Together, those volunteers and the NECC students worked     5     (clear) rubbish out of a three-story building. They put on protective suits and gloves    6    they entered the building.

Inside the building, the students saw nothing but broken walls and doors and pieces of the building     7    (lie) all over the place.

The students returned to school with     8    sense of achievement, a feeling     9    they helped people in need. I was remarkable how a community lost so much and was still able to recover, and this left the deepest impression    10    the students.

In August 2014, paleoanthropologist (古人类学家)Yingqi Zhang and his team went down into a sinkhole on the hunt for Gigantopithecus, the largest known primate(灵长类动物)to ever live. They came back out with a mix of bones from the unfortunate     1     (creature) that had fallen into the natural "death trap". None of those bones belonged to the extinct ape, but the team was in for a surprise: The mix included a 22,000-year-old lower jaw from     2    ancient panda. And within its worn edges, the jaw contained     3     is now the world’s oldest sample of panda DNA. Moreover, the genetic evidence     4    (show) that the bone comes from a     5    (previous) unknown lineage of giant panda. This animal may have been specifically adapted to    6    (live) in its subtropical home, suggesting that the black-and-white beasts were once much     7    (diverse) than they are today, the authors argue in a paper     8     (publish) in the journal Current Biology. While the     9     (conclude) about panda diversity is probably not revolutionary, the team's work collecting ancient DNA from the degraded fossils is     10     great significance.

Beijing embraces second snow this winter. The second snowfall of Beijing hit the capital Sunday evening,     1     (affect) traffic routes and scenic areas on Monday.

Starting at about 7 pm on Sunday, the snow fell from the city’s south,     2     (gradual) covering the entire capital     3     turning to moderate snow Monday morning, according to the Beijing Meteorological Bureau. The snowfall ended at noon and the blue alert     4     (issue) for a blizzard (暴风雪) was removed in the afternoon.

More than 50,000 workers and over 6,500 snow removal     5     (vehicle) were set up     6     (ensure) road safety. Flights and subway lines, as well as bus routes, have been affected when     7     snow hit the capital.

On Sunday Beijing issued a blue alert for a blizzard, the first blizzard alert this winter. A yellow alert for     8     (ice) roads was issued as well. China has a four-tier color-coded weather warning system, with red representing the most severe, followed     9     orange, yellow and blue.

In late November, the capital     10     (experience) its first snow of the winter.
