Dogs are often referred to as “man's best friend”. But MacKenzie, a four-pound Chihuahua (奇瓦瓦狗), who

was named winner of the 2020 American Hero Dog competition, is making the world a better place for humans

and animals alike. Often called the “Oscars for dogs”, the award recognizes dogs who make great contributions to

society.

This year's competition attracted over 400 competitors from across the country. While all were impressive, it

was tiny MacKenzie who won the judges' hearts. Born at a rescue shelter in Hilton, New York, in 2013, she had a

cleft palate (腭裂) that required her to be tube fed for the first year of her life. A life-saving operation, performed

in 2014, gave her the ability to eat and drink independently, enabling the tiny dog to focus on doing what she

loved most: taking care of others.

The seven-year-old Chihuahua is now gainfully “employed” by the Mid Foundation, a Rochester, New

York-based non-profit organization that shelters and cares for animals born with disabilities. MacKenzie's official

job is “to provide love and care for baby rescue animals born with birth defects”. The Chihuahua is good at her job

and hasnurturedmany different species-from puppies to kittens to turkeys, squirrels, birds and even a goat. She

acts as their mother and teaches them how to socialize, play, and have good manners.

In addition to her role as an animal caretaker, MacKenzie also has the important job of greeting the

foundation's volunteers and friends. The incredible dog, who has lost her ability to bark, also visits area schools to

help children understand physical disabilities in both animals and people. Her heart-warming and inspiring story

makes MacKenzie worthy of America's top dog honor!

4. What made MacKenzie American Hero Dog?

A. Being man's best friend. B. Her struggle with disabilities.

C. Rescuing animals with disabilities. D. Her contributions to a better world.

5. What can we infer about MacKenzie from Paragraph 2?

A. Her growth path was not easy. B. She was deserted by her owner.

C. She was operated on at two years old. D. She still needs taking care of by others.

6. What does the underlined word “nurtured” in Paragraph 3 mean?

A. Trained. B. Comforted. C. Tended. D. Abused.

7. Which can be a suitable title for the text? A. MacKenzie—The Most Hard-working Dog B. MacKenzie—America's “Most Heroic Dog”

C. Chihuahua—Inspiration of Positive Energy D. Chihuahua—Appeal for Animals' Protection

C

Owning a dog is associated with a significantly lower risk of heart disease and death, according to a

comprehensive new study published by a team of Swedish researchers on Friday in the journal Scientific Reports.

The scientists followed 3.4 million people over the course of 12 years and found that adults who lived alone

A

I started working with my hands at a young age. The youngest of five brothers, I took on the role as a

“maintenance (维修) man” at an early age for our family’s small grocery store. Often my dad wouldn’t give me a

clear idea of how something shouldbe done, so I just had to figure it out by researching or through trial and error.

Fast forward to 2016 and those problem-solving skills would become the focus of Tippecanoe High School’s

Homebuilding class. I knew I wanted to teach the students skills that went beyond just being able to hammer nails

or cut pieces of two-by-fours. The problem was that we didn’t have the resources at the time to do much else.

The idea of attracting some type of funding seemed very important. Designing, building and selling a tiny house on

天问一号火星探测器于2020年7月23日成功发射,2021年2月10日与火星交会,成功实施捕获制动进入环绕火星轨道,对预选着陆区进行了3个月的评查后,于2021年5月15日成功实施火星着陆。2021年5月22日,祝融号火星车成功驶上火星表面,开始巡视探测。完成下面小题。

1.下列选项中描述正确的是( )

A.降落在火星上的探测器是天体 B.与火星相邻的行星是金星和木星

C.围绕火星运转的探测器属于卫星 D.火星不属于类地行星

2.火星属于( )

A.地月系 B.太阳系 C.河外星系 D.其他恒星系

3.科研队对火星进行生命探测时首先查找液态水存在迹象,原因是( )

①存在液态水,说明可能存在适宜的温度①有液态水才能形成云雨现象①液态水可以形成多样的地表形态①生命起源于海洋,有液态水才可具备此基本条件

A.①① B.①① C.①① D.①①

【答案】1.C 2.B 3.D

【解析】1.降落在火星上的“祝融号”火星成为火星的一部分,天体的一部分不能单独被称为天体,A错误;太阳系中八大行星距离太阳由近及远依次为水星、金星、地球、火星、木星、土星、天王星和海王星,因此与火星相邻的行星是地球和木星,B错误;火星属于行星,因此围绕火星运转的探测器属于卫星,C正确;火星轨道在地球轨道外围,因此属于地外行星,D错误,故选C。

2.火星是太阳系中的八大行星之一,属于太阳系,B正确;地月系,只有地球和月球,A错误;太阳系属于恒星系,D为其他恒星系错误;太阳系位于银河系之中,C河外星系,错误。故选B。

3.存在液态水,则说明存在生命物质的温度适宜,则有可能探测到生命迹象,①符合题意;云雨现象和多种多样的地表形态不是生命存在的必要条件,因此①、①不符合题意;研究发现,地球生命起源于海洋,由此推断,有液态水才可能产生海洋这种孕育生试卷第2页,共14页 命的基本条件,①符合题意。综上所述,D符合题意,排除ABC。故选D。
