20．标题选择题。根据文章可知主要讲了Black Beauty从被虐待到被拯救的过程，强调善良与关爱的重要性，可见 "善意拯救了马的生命" 是贯穿全文的主旨，最适合作为标题，故选D。
（2025七下·深圳期末）阅读下列短文，从每小题所给的A、B、C、D四个选项中，选出最佳选项。
The mangrove wetlands(红树林湿地)of Shenzhen's Futian and Hong Kong's Mai Po are very valuable. Every year, many waterbirds fly from East Asia to Australia. These wetlands are a key place for them to rest. These years, Shenzhen and Hong Kong have worked together to protect these important wetlands.
Why are these mangrove wetlands so important Because they are like nature's protectors. They make a natural wall, protecting coasts from big storms(暴风雨). Besides, the thick forest of mangrove frees provides a perfect home for birds. They build nests there and look after their babies. "Even during storms, baby birds are safe in the mangroves, "said Simon Wong from Hong Kong's nature team. What's more, mangroves help take in CO2 and clean the water. As a result, they are helpful for both nature and humans.
To protect the wetlands together, Shenzhen and Hong Kong have used different ways since 2023. One of them is to protect birds' homes with the help of modern AI technology. Thanks to their efforts, the population of endangered birds in the wetlands has grown. For example, there were only about 300 black-faced spoonbills(黑脸琵鹭)around 30 years ago. Now there are nearly 7, 000.
In November 2024, the two cities started a new part of their teamwork. The International Mangrove Center(IMC)in Shenzhen opened. The IMC does research on mangrove protection, shares useful ideas and gives classes to the public. Its opening helps Shenzhen and Hong Kong work better to protect the wetlands. It also shows the world how cities can join hands to protect the environment.

C．t=2s时刻拉力的瞬时功率在整个过程中最大
D．t=1s到t=3s这段时间内合力做功为零
【答案】A,D
【知识点】功率及其计算；动能定理的综合应用；运动学 v-t 图象
【解析】【解答】该题考查了力做功的条件以及功的计算方法，求合力做功时可以先求各个力做的功，再求代数和，也可以先求出合力，再根据W=F合Lcosθ进行计算，也可据动能定理求解。AB．解析对物块运动的整个过程运用动能定理得WF－Wf=0
即拉力做的功等于物块克服摩擦力做的功，故A正确，B错误；
C．在0～1s时间内，拉力恒定且大于摩擦力，物块做匀加速运动，速度增大，t=1s时，速度最大，拉力的瞬时功率最大；t=2s时，物块匀速运动，拉力等于摩擦力，所以t=2s时刻拉力的瞬时功率不是最大的，故C错误；
