1.1.

A buys

B makes

C finds

D fixes

解析：选D。D 考查动词词义辨析。四个选项词义分别为：A. buys（购买）；B. makes（制作）；C. finds（发现）；D. fixes（修理）。根据后文原文第二段首句“Brayden learned to fix computers（布雷登学习修理电脑）”可形成上下文呼应，再结合后文他将电脑赠予有需要的人，可知他的行为是修理旧电脑。其余选项不符合文章核心行为，因此选D。

2.2.

A by hand

B by himself

C by machine

D by chance

解析：选B。B 考查介词短语辨析。四个短语含义：A. by hand（手工）；B. by himself（独自、靠自己）；C. by machine（用机器）；D. by chance（偶然）。此句意为“布雷登______学会了修电脑”。后文提到他从家里的旧设备开始摸索，然后去买零件，还看视频学习，整个过程没有提到老师或培训班，强调的是自学。by himself意思是“独自地、靠自己”，符合语境。by hand“用手”，by machine“用机器”，by chance“偶然”，都不符合自学的语义。故选B。

3.3.

A schools

B parks

C stores

D zoos

解析：选C。C 考查名词词义辨析。四个选项词义：A. schools（学校）；B. parks（公园）；C. stores（商店）；D. zoos（动物园）。他要“买需要的东西”，自然要去商店。second-hand stores就是“二手商店”。学校、公园、动物园都不是购买电脑零件的地方。本题考的是根据“buy things”来选择正确的购买场所。故选C。

4.4.

A tiring

B worrying

C rewarding

D relaxing

解析：选C。C 考查形容词词义辨析。四个选项词义：A. tiring（令人疲惫的）；B. worrying（令人担忧的）；C. rewarding（有意义的、值得的）；D. relaxing（令人放松的）。根据后文“He feels great that his skills can help others.（他为自己能帮助别人而感到开心）”可知，看到电脑帮助到他人，对他来说是最有意义、最值得的事情。其余形容词不符合正面积极的情感语境，因此选C。

5.5.

A for

B as

C to

D from

解析：选A。A 考查介词搭配。“use sth. for sth.”是固定搭配，表示“把某物用于某目的”。这里指孩子们用电脑来做学校作业。as意为“作为”，to是不定式符号（如used to do），from是“来自”，都不能正确表达用途。所以要用介词for。故选A。

6.6.

A praise

B teach

C doubt

D protect

解析：选C。C 考查动词词义辨析。四个选项词义：A. praise（表扬）；B. teach（教导）；C. doubt（怀疑）；D. protect（保护）。根据前文“But volunteering is not always easy.（志愿工作并不总是一帆风顺的）”可知，本段讲述他遇到的困难。结合后文“because he is very young（因为他年纪很小）”，可推断成年人因为他年纪小而怀疑他的能力，这是他遇到的阻碍，其余选项不符合负面困境的语境，因此选C。

7.7.

A hopeful

B careful

C helpful

D thankful

解析：选B。B 考查形容词词义辨析。四个选项词义：A. hopeful（满怀希望的）；B. careful（细心的、仔细的）；C. helpful（乐于助人的）；D. thankful（感恩的）。前文提到“once he broke a computer screen when he was cleaning it（他曾经清理电脑时弄坏了电脑屏幕）”，这次失误让他吸取教训，学会变得更加细心，避免再次出错。只有B选项符合因果逻辑，因此选B。

8.8.

A but

B and

C or

D so

解析：选A。A 考查连词辨析。四个连词用法：A. but（但是，表转折）；B. and（并且，表并列）；C. or（或者/否则，表选择/条件）；D. so（所以，表因果）。前半句“Brayden loves technology（布雷登热爱科技）”，后半句“he tries to keep a balance in his life（他努力保持生活平衡）”，热爱科技却不沉迷，主动平衡生活，前后是转折关系，因此选A。

9.9.

A here

B there

C outdoors

D home

解析：选C。C 考查副词词义辨析。四个选项词义：A. here（在这里）；B. there（在那里）；C. outdoors（在户外）；D. home（家）。前文“He takes breaks from screens（他远离电子屏幕休息）”，为了平衡生活、远离屏幕，对应的休闲方式就是去户外活动。here“这里”、there“那里”指代不明；home“家”虽然也有可能，但不如outdoors能体现出门活动的意味。因此选C。

10.10.

A find

B know

C call

D help

解析：选D。D 考查动词词义辨析。四个选项词义：A. find（找到）；B. know（了解）；C. call（称呼、打电话）；D. help（帮助）。全文核心讲述布雷登通过修电脑、帮扶公益救助他人，文末总结主旨：你可以通过多种方式帮助他人，且后文“use what you love to help your community（用热爱助力社区、帮助他人）”形成主旨呼应，因此选D。
