2．C　解析：主旨大意题。通读全文可知，本文的主题句为“China's domestically developed Beidou Navigation Satellite System has been widely used in many public sectors and business fields at home and abroad.”，即文章主要介绍了北斗卫星导航系统在国内外的广泛使用，故C项正确。

(2021·湖南四校高三调研)One of the costs of being a lover of old trees is the all­too­frequent loss of a_beautiful_soul_you've_grown_fond_of．Last summer was harder than most for old trees and their human supporters.The spring's nonstop rain flooded soils and caused root systems of many large, old trees to rot in part.Then, when the summer came, trees could not tap deep sources of water that would normally have maintained (维持) them.Many valuable old trees died.

When I volunteered for the Mount Rainier Tree Commission, I heard from many people concerned about their trees.We had little to offer them.That's because public and private urban tree resources and programs were aimed almost entirely at planting trees but not at maintaining trees.No state or province program that I could find provided any financial resources for maintaining tree health.Small and under­resourced cities such as ours were on their own.

This is backward.Scientists are learning that large, old trees are the most valuable, especially in cities.They put on wood fastest and take the most carbon out of the air.They harbor the most wildlife.They can lower summer temperatures by 20 degrees or more.In a recent study, researchers found that Boston would get more benefit from keeping the trees it has alive than from planting new trees.There's reason to think this finding would apply in other cities, too.

Now, our public and private tree programs often ignore old trees until it is too late.As long as we abandon our old trees, planting more is merely to keep pace with growing losses.We want trees to help protect us, but we leave them unprotected.Consider this in the human world：Nobody would send a baby into the world and expect it to just make it.Children need caring for and it's why we have schools and child health­insurance programs.We could get so much more out of our trees if we just put a little more into them.

4．What does the underlined part in paragraph 1 suggest?

A．Strong determination to plant trees.

B．Real regret at growing old trees.

C．Great concern about tree problems.

D．Deep love for valuable old trees.

5．Why was the author almost powerless to help people worried about their trees?

A．The urban tree programs were faced with financial problems.

B．The author's knowledge of maintaining tree health was limited.

C．The focus of the tree resources and programs was on tree planting.

D．The organization the author volunteered for was short of tree experts.

6．The author argues in paragraph 3 by________．

A．comparing different cases

B．presenting research findings

C．referring to scientists' sayings

D．carrying out some experiments

7．Why does the author give the example of nursing babies in the end?

A．To stress the importance of tree insurance programs.

B．To show the close connection between trees and babies.

C．To advocate protecting trees as humans care for babies.

D．To persuade human beings to pay more attention to babies.

【解题导语】　本文是一篇议论文。老树给我们带来很多好处，但是我们往往只想到种植树木而忽视保护现有的树木。

4．D　解析：推断判断题。画线部分的上文说的是“成为老树爱好者的代价之一就是经常失去……”，画线部分的字面意思是“一个你喜爱的美丽灵魂”，又结合第一段最后一句“Many valuable old trees died.”即可推断，美丽的灵魂说的就是珍贵的老树，因此画线部分说的是对珍贵的老树的热爱，故D项正确。

5．C　解析：推理判断题。根据第二段内容可知，作者几乎无能为力的原因是“公共和私人城市树木资源和项目几乎完全是为了种树，而不是维护树木”，故C项正确。

6．B　解析：推断判断题。通读第三段可知，本段主要通过呈现研究发现说明了老树带给我们的好处，故B项正确。

7．C　解析：推理判断题。作者在最后一段提到我们想要树木保护我们，但我们却不保护它们，紧接着作者打了一个比方：人们生下婴儿后不可能对其不管不顾就期望婴儿能成功，孩子需要照料，我们就有了学校和儿童健康保险项目。由此可推知，作者提到照料婴儿是为了提倡像人类照顾婴儿那样保护树木，故C项正确。
