The masked shrew is one of the smallest mammals(哺乳动物) in North America, only a few inches long. However, it recently made a giant jump. Over the past few decades, the tiny shrew has migrated more than 4,000 feet on both sides of the Rocky Mountains. And it’s not the only one.

Studies in other parts of the world have suggested that mountain animals are climbing higher. Lead study author Christy McCain, an ecologist at the University of Colorado Boulder, and her co-authors Sarah King and Tim Szewezyk wanted to show it is true in the Rockies.

The new study looked at 47 different species of small mammals in the Colorado Rocky Mountains. First, the researchers studied the small mammal samples (样本) collected in Colorado over the last few decades and built a database on where these mammals were typically found and how high up. Next, they conducted a series of field surveys in the Colorado Rockies, counting small mammals and recording where each species is found today. They then calculated how much each mammal population has moved over the last few decades.

They found that 26 of the 47 species studied had moved upward over time. Masked shrews were among the species with the largest jumps, climbing a total of about 4,500 feet. McCain noted that species with the largest upward jumps tend to share some important characteristics. Most of them are animals specifically adapted to cold weather. 11 of the 47 mammal species actually shifted downward. McCain noted they may be less sensitive to mountain warming. Six species do not appear to have changed at all. And four species have completely disappeared from the mountains in the period between the 1980s and now.

“This is the first indication,” McCain said, “that large animal communities are responding to climate change.” The findings are consistent with the conclusions of other studies around the world — that mountain ecosystems are sensitive to climate change and wildlife in these places is already responding to the pressure, both of which can urge humans to change the current situation.

【小题1】Why did Christy McCain and her team do the study?
A.To collect data of mountain animals.B.To urge humans to change the situation.
C.To prove the previous conclusions.D.To assess the effects of climate change.
【小题2】What does the study find about mountain mammals?
A.Many species have disappeared.B.None have shifted downward.
C.Those going higher are sensitive to cold.D.Many are affected by climate change.
【小题3】What can the findings function as?
A.A wake-up call.B.A climate reminder.
C.A pressure response.D.A situation changer.
【小题4】What’s the main theme of the text?
A.Mountain mammals climb higher to beat the heat.
B.Cold-adapted species suffer a lot in the Rockies.
C.Climate change is making the Rockies unlivable.
D.Small mammals are vital to mountain ecosystems.

Beijing No 4 Intermediate People’s Court said on Thursday that it concluded 77 cases of smuggling (走私) precious animal products from the beginning of 2015 to June this year, with about 40 percent of defendants (被告) given prison terms of three or more years. The products were found to be frequently made of body parts of some endangered wild animals such as elephants, turtles, bears and wolves, Wang Jing, vice-president of the court, told a news conference.

“Most of the defendants were migrant workers, students and tourists coming back to China, “Wang said. “Some aimed to sell the products for profits or send to friends and family members as gifts, while they wanted to use them to help with diseases.”

Wang explained that some of the defendants received heavier penalties (惩罚), such as a long-term imprisonment and a high fine, because the animal parts they smuggled were from animals listed on the national key protection of wildlife or related to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). For example, a defendant surnamed Yan was sentenced to 10 years in prison, along with 200,000 yuan ($27, 968) in fines, for smuggling 393 fish bladder products, the court said. Yan was caught while arriving at the Beijing Capital International Airport from Mexico on March 21, 2018, and the suspected products were discovered by the customs staff members in Yan’s luggage. The products were later identified as being made of drum fish in Gulf of California, and the fish is listed on the CITES, the court said, adding that the products were worth of about 2.51 million yuan ($351,000).

To effectively fight the crime, the court has issued a guideline on the smuggling of precious animal products to help judges accurately apply laws and unify (统一) the standards of relevant case hearings.

On Thursday, the court also disclosed four other smuggling cases, showing its determination and effort to protect precious animals by rule of law.

【小题1】What does Wang Jing mainly express in paragraph 2?
A.The diseases that the animal products can be used to cure people of.
B.The way the defendants managed to get the animal products abroad.
C.The reasons why the defendants brought the animal products from abroad.
D.The people who the defendants were supposed to sell the animal products to.
【小题2】What can be learned about the defendant surnamed Yan from paragraph 3?
A.Yan was sentenced to one decade in prison without any fines.
B.Yan was caught when trying to make a deal with someone.
C.Yan’s products were made of a kind of endangered fish.
D.Yan was a migrant worker, who came from Europe.
【小题3】Which can replace the underlined word “disclose” in the last paragraph?
A.Have some doubts about.B.Feel a little upset about.
C.Try to hide the truth about.D.Give people information about.
【小题4】What can be a suitable title for the news report?
A.Beijing court handles 77 cases of smuggling animal products
B.Beijing court makes an effort to recognize wild animals products
C.Beijing court helps judges apply laws about smuggling animal products
D.Beijing court issues guideline on smuggling of precious animal products

Have you ever taken a look at a few lovely chickens and desired to touch and kiss them? Apparently, for some people the urge is hard to resist. However, according to an updated warning by the Centers for Disease Control (CDC) doing so could spread dangerous—maybe even life-treatening-Salmonella. So, no matter how irresistible those little feathered birds may seem, avoid giving them a kiss.

This isn’t the first time the CDC has warned against physically touching or kissing your poultry. Back in 2018 Halloween, they advised against dressing the birds up for fear of spreading Salmonella. Then again, in May this year, with 474 cases reported, another warning was issued. According to interviews with 271 of those affected, 77 percent had been in contact with poultry before getting sick.

“Backyard poultry, like chickens and ducks, can carry Salmonella bacteria even if they look healthy and clean,” writes the CDC. These bacteria can easily spread to anything in the areas where the poultry live. You can get sick from touching your poultry or anything in their environment and then touching your mouth or food, and swallowing Salmonella bacteria.

Most people who come into contact with the Salmonella bacteria will experience diarrhea (腹泻), fever, and stomach cramp. Children are particularly affected—one in three sick people are below the age of five, which is intelligible given their weaker immune systems and natural love for the birds.

The CDC recommends that parents shouldn't let little children touch chicks, ducks, or other backyard poultry and make sure that if they do, they should wash their hands thoroughly afterward. Likewise, adults are instructed to do the same after touching backyard poultry and their eggs should be cleaned, stored, and cooked correctly to avoid the infection of Salmonella.

This might be easier said than done—for many people, backyard chickens are beloved—but if you really love them, stop physical displays of affection in case you end up with Salmonella bacteria on your face. It turns out to be a bit of harm.

【小题1】Why does CDC repeatedly warn people not to kiss chickens?
A.To protect the poultry.B.To show love to chickens.
C.To get rid of Salmonella.D.To stay safe from potential danger.
【小题2】How is paragraph 2 mainly developed?
A.By giving examples.B.By showing statistics.
C.By making comparison.D.By interviewing victims.
【小题3】What does the underlined word “intelligible” probably mean in paragraph 4?
A.Understandable.B.Irresistible.C.Unavoidable.D.Controversial.
【小题4】What does the author intend to do in the last paragraph?
A.Stress the importance of affection.B.Add more background information.
C.Provide some suggestions for the readers.D.Summarize the theme of the passage.
Besides containing attractive flowers, trees and other plants that beautify the community, eco­friendly rain gardens are healthy for the environment and the people living and working nearby.
A rain garden is not very different from a traditional garden. It is just a far more eco­friendly garden. Usually it is built lower than the ground. Rain gardens make smart use of rain and storm water by temporarily holding water from rain and storms and letting it soak(浸入)slowly into the ground before it runs into streams or enters the public drinking water supply.ZXXK]
Thus, a rain garden keeps the water, allowing it to be used as needed by plants in the rain garden, rather than flowing immediately into nearby streams and going unused. The water will soak slowly into the ground within a day or two. This creates an advantage that the rain garden does not allow mosquitoes to breed. This is a simple, attractive, and eco­friendly “green” way to treat storm water.
What’s more, planting a rain garden helps reduce pollution and improve the environment. Without using expensive machinery and chemicals, rain gardens remove harmful chemicals in the rainwater and cut down on the amount of pollution reaching streams and rivers by up to 30%.
Native plants are recommended for rain gardens because they are more used to the local climate, soil, and water conditions. They may attract local wildlife such as native birds. Water your rain garden immediately after planting and once a week, unless you have had at least an inch of rain during the week. Once native plants establish the necessary root system, they will require little care.
Often, local governments and private businesses develop large rain gardens in their yards and in public parks as a way to improve the environment and solve flooding problems. However, you don’t need to be a professionally environmental engineer to create a rain garden. As long as you’re eco­conscious homeowners, you can help the environment by building smaller rain gardens in your yards.
【小题1】Which of the following is NOT true for the function of rain gardens?
A.They are good for living conditions.
B.They increase pollution.
C.They can beautify the community.
D.They improve the environment.
【小题2】Which of the following is the eco­friendly function of rain gardens discussed in Paragraph 4 ?
A.They can help reduce the pollution problem.
B.They can keep the rain and storm water.
C.They can be healthy for the people around.
D.They can make the environment more beautiful.
【小题3】One of the main reasons why native plants are recommended is that     .
A.they cost less and are much easier to get
B.they may attract local wildlife to come
C.they require little care from the local gardener
D.they are more used to the local growing conditions
【小题4】What do we know about rain gardens?
A.They need little water after all the plants are planted.
B.They may attract local birds and change the local climate.
C.They usually need at least an inch of rainwater a week.
D.They may reduce the water pollution problem by 70%.
