五、选词填空

【答案】本文主要介绍了DeepSeek的相关信息。

1.句意：这些模型非常智能，可以做很多事情。根据“are”可知，空处应用形容词作

表语；根据“candomanyIhings”可知，这些模型非常智能，形容词smart“智能的”符

合语境。故填smarto

2.句意：它可以解决数学问题，编写简单的代码，像人类一样聊天。根据“mathsproblems"

可知，此处指解决数学问题，动词solve“解决”符合语境；情态动词can后面接动词原

形。故填solve。

3.句意：其他人工智能系统需要许多例子来学习，但R1会自己提高。根据“OtherAI

systemsneedmanyexamplestolearn,butRIimprovesby...”可知,RI靠自己本身提高,by

oneself意为“靠某人自己”，因此空处应填it的反身代词itself,用于指代R1本身。故

填itself。

4.句意：这就像教鸟儿飞翔。根据"abirdiofly”和所给单词可知，此处指教鸟儿飞翔，

动词teach“教”符合语境;空前的“like”是介词，其后接动词-ing形式。故填teaching。

5.句意：它尝试得越多,效果越好。根据"Themoreittries,the...itworks.”可知，此处

应用“the+比较级...,the+比较级…”结构表示“越……就越……”；结合所给单词可知，

空处应填副词well"好”的比较级betler修饰动词workso故填bettero

6.句意：人工智能对学校和小企业是免费的。根据“is”可知，空处应用形容词作表语；

结合所给单词可知，形容词free“免费的”符合语境。故填free。

7.句意：现在，即使是村民也可以使用人工智能，而不用担心费用。根据"Noweven

villagerscanuseAIwithoutworryingabout...”和所给单词可知，此处指不用担心费用，名

词cost“费用”符合语境；cost既可作可数名词又可作不可数名词，所以空处可填cost

或costs。故填cost(s)。

8.句意：但是也有挑战。根据"Butthereare...”可知，空处缺少名词作主语；结合下文

“AlsometimesmakesmistakesinlanguageslikeGermanorRussian.”和所给单词可知，此

处指AI也面临着挑战，名词challenge“挑战”符合语境；根据“are”可知，空处应用

可数名词复数。故填challenges。

9.句意:我们希望人工智能能够帮助世界上的每一个人。aroundtheworld“全世界，世

界各地”。故填around。

10.句意：它告诉我们，伟大的事情来自于创造力和努力，而不仅仅是金钱。end用于

连接并列成分，所以空处应填一个和hardwork存在并列关系的名词；结合所给单词可知，

create的名词形式creativity“创造力”符合语境。故填creativity。

六、任务型阅读

【答案】本文主要讲述了四个美国学生对2045年世界样貌的看法，包括人类在火星的生

活可能性、地球的修复、未来职业以及机器人对工作的影响等。

1.根据第二段首句“In2045,thekidsthink,humanswillbeabletoliveonMars.”可知，在

孩子们看来，2045年人类洛能够在火星上生活。故填OnMars.

2.根据第三段中Sorensen的话"It'stimetofixitnow."saysSorensen."It'snotgoing

tofixitself.”可知，Sorensen认为现在是时候修复地球了，地球不会自己修复。故填It'stime

tofixitnow.It'snotgoingtofixitself.

3.根据最后一段中Stark的话“There'Hbenomorefactoryjobsbecauserobotscanjustdo

everything.”可知，Stark说将不再有工厂工作是因为机器人可以做任何事情。故填Because

robotscandoeverything.

4.这是一个开放性问题，答案因人而异。但可以根据文章内容和常识来回答。故填Ithink

theEarthwillbeagreenerplacetolive.Humanscaremoreabouttheenvironmentalprotection.

Moretreeswillbeplantedaroundbuilding
