Many people think that hippos (河马) are cute and funny-looking. They are really fat and they have short, thick legs. They also have little round ears that wiggle (摆动) sometimes.

Hippos look funny, but you shouldn’t judge a book by its cover. Hippos are extremely violent and dangerous. In fact, they kill more people than any other animal in Africa. Think of how many dangerous animals that Africa has. It has got crocodiles, snakes, lions, elephants and many more. Hippos are more dangerous than all of them.

Hippos are naturally very dangerous animals, but there are some situations that make them even more dangerous than normal. They are very territorial. That means that they stay in one area which they consider to be their private area. If a person or animal enter a hippo’s area, the hippo will attack. Hippos also often attack when they are returning to the water. Hippos eat on land and return to water at dusk. If a hippo sees an animal when it’s returning to the water, it will become violent.

Hippos are so strong that they often kill crocodiles. There are two reasons that explain why hippos and crocodiles often fight. First of all, hippos and crocodiles live in the same areas. Since hippos are territorial, they don’t like having crocodiles nearby. Also, crocodiles often eat young hippos. For that reason, adult hippos frequently kill crocodiles.

Mother and daughter hippos have close relationships. However, hippos don’t have any other close relationship with each other. Hippos often live together in large groups, but scientists don’t know why. It’s hard to study the behaviour of male and female hippos, because males and females look the same.

Hippos are violent, but they are herbivores. A herbivore is an animal that eat only plants. An adult hippo eats about 50 kilograms of plants every day. Hippos are much more comfortable in the water, but they can run fast on land. Their top speed is about 19 kilometers per hour. That’s much faster than humans can run.

文章大意:这是一篇说明文。文章主要讲述干旱和杀虫剂等有害化学制品导致智利的蜜蜂大量死亡。

【推荐1】The South American nation of Chile has been experiencing bad droughts for the last 13 years. This serious lack of water has led to fewer flowers and, as a result, fewer honeybees. Some chemicals used to kill insects harmful to crops called pesticides (杀虫剂), also hurt bees.

Beekeepers in Chile are concerned. Carlos Peralta and his brother Marco are beekeepers. Carlos has seen the number of his honeybees dropping sharply. He said he had lost about 300 hives (蜂巢) since the start of November 2021. A hive can hold tens of thousands of bees. Losing so many bees left Peralta with a difficult choice. He could keep his remaining 900 hives alive with man-made honey, or he could move the hives to a place where there are more flowers. “If the bees die, we all die… The bee is life,” Carlos said. He was describing the important job that bees have to pollinate (授粉) plants in the wild and for food growers.

So Carlos decided to move his beehives about 1, 000 kilometers to the south, to a place called Puerto Montt. However, his brother Marco chose to stay in Colina with his bees rather than join Carlos in the south. Marco said he feared losing bees to pesticides if he moved.

An FAO study in 2018 found that Chile’s introduction of pesticides had grown by 460 percent over the previous 20 years. Beekeepers blame (责备) this increase for their losses. Chile’s honey exports (出口) have dropped over the past four to five years.

Carlos Peralta said, “You enter a fruit garden with your bees and you don’t know if you'll come out with living bees or dead ones.”

His brother Marco has been feeding his bees with sugar water. However, this food leaves the bees unable to produce honey. “The bees grow weak with sugar water,” said Mario Flores.

Before the drought, beekeepers would use the sugar food during the winter months. But now they use it almost all year.

1. What does Carlos think of the survival of bees according to paragraph 2?
A.It is related to beekeepers’ skill.B.It is a matter of life and death for him.
C.It is important to the water system.D.It is a must for his country’s exports.
2. Why did Marco decide to keep his bees where they were?
A.To save the cost of moving.B.To benefit the plants nearby.
C.To avoid harmful chemicals.D.To leave the chance to his brother.
3. What happens when bees are fed with sugar water?
A.Their health can be harmed.B.They gather more honey.
C.They are too full to work.D.Their honey is of poor quality.
4. Which of the following can be the best title for the text?
A.Dry Conditions and Poisonous Chemicals Are Killing Bees
B.Nature Balance of Chile Is Being Destroyed by Beekeepers
C.Harmful Chemicals Are Bringing Danger to Living Things
D.Two Brothers’ Different Ways to Keep Bees Have Different Results

文章大意:本文是记叙文。文章讲述了一只名叫Pepper的狗在冬天湖边散步时不慎掉入冰洞,随后被消防员和救援人员成功营救的故事。

【推荐2】It only takes one wrong step near a lake in the winter for disaster to happen. Pepper, the dog and his mom found that out the hard way.

The two of them were taking a morning walk in Chicago along Lake Michigan when Pepper, a 7-year-old dog, got free of its rope, slipped on some rocks, and fell onto the ice sheets of the lake. As Pepper tried to climb back up to his human owner, the ice around him broke, and he began floating (漂浮) away!

Since the water was so cold, Pepper should be saved as soon as possible. As Fire Deputy District Chief Jason Lach said, hypothermia (a serious medical condition caused by very low temperature) can start within several minutes. Thankfully, firefighters were already nearby practicing underwater ice dives.

Just 10 minutes later, 40 rescue (救援) workers arrived, along with fire department vehicles and a helicopter. By the time the officials in the helicopter noticed Pepper, he and his ice float were 500 feet out into the lake. Firefighter Chris Iverson dove into the water and swam out to Pepper. Chris calmed the dog down and tied him to a safety sling (吊索). Meanwhile, firefighter Emerson Branch swam out with a rapid deployment craft, which he and Chris used to bring Pepper safely to shore. The rescue only took about 15 minutes. When the firefighters reached dry land with Pepper, they dried him using a towel and played the pass-the-dog to get him back to his human owner.

Caretakers at Veterinary Emergency Group Hospital made sure Pepper was OK. But Jason hopes his rescue will be a lesson for others. “The dog was good, warmed up to its owner, and went on its happy way,” Jason said. “But stay off the ice. It’s never safe, …Step into a hole, and you’re out of sight.”

1. What happened to Pepper one morning?
A.He lost his owner.B.He was trapped in a lake.
C.He got missing suddenly.D.He was covered by ice sheets.
2. What seemed to be the first danger to Pepper?
A.The cold water.B.Poor medical conditions.
C.Rescue equipment shortage.D.The changeable temperature.
3. What can we learn from Paragraph 4?
A.The rescue lasted about an hour.B.Pepper got to the shore alone.
C.The rescue was highly effective.D.Pepper reacted calmly all the time.
4. What is Jason’s suggestion?
A.No going near the ice.B.No walking dogs by a hole.
C.Taking good care of pets.D.Warming up well before exercise.

文章大意:本文是一篇说明文。文章主要说明了科学研究发现,蜂群产生了一种大气电荷。文章解释了研究开展的经过以及未来的方向。

【推荐3】While Ellard Hunting and fellow researchers were out studying the weather at a field station in England, they noticed something unexpected on their instruments. Though there was no storm coming, the scientists’ electric field monitors recorded a strange increase in atmospheric electric charge(电荷) .

Nearby, honeybees that lived in on-site hives were swarming (蜂拥) as they tried to find a new home. When the team took a closer look at their data, they discovered that the swarming honeybees had created an atmospheric electric charge. The researchers shared more details about their findings in the journal Science.

“This is the first report of biology as a source of space charge.” says Hunting, a biophysicist at the University of Bristol in England. Scientists had known that individual bees carry a small charge while flying through the air, caused by the friction of their body parts against the air and each other. It’s similar to how rubbing a balloon on a piece of cloth creates static electricity (静电). Scientists believe a bee’s charge helps pollen (花粉) stick to it and signals to other bees which flowers have already been visited. But until now, researchers had never recorded such a high voltage (电压) among swarming honeybees.

In terms of electricity generation, a bees warm’s charge isn’t so impressive:It would take about 50 billion bees to power an LED light. But compared to the charges produced by common weather events, the bees’ charge density was six times greater than an electrified dust storm and eight times greater than a thunderstorm cloud.

Scientists hope to continue exploring how biology influences physics and are curious to know if something similar is happening with other wildlife, such as birds and bats.

1. What were the researchers doing when something unexpected on their instruments happened?
A.Studying weather events.B.Testing their instruments.
C.Recording insects’ behavior.D.Looking for honeybees’ new home.
2. What’s the function of a bee’s charge?
A.To help the bee fly fast.B.To signal to other bees.
C.To find pollen more easily.D.To avoid losing their way.
3. What will the scientists continue to study next?
A.The wide application of biology.B.Measures to protect birds and bats.
C.The influences of dust storms on wildlife.D.Whether other wildlife can produce electric charge.
4. Where is the text from?
A.A novel.B.A fiction.C.A magazine.D.A leaflet.
