错误:The key question is if we should adjust our strategy.
whether 可与 or not 连用,if 不可

与现在事实相反:从句用过去时(be 动词用 were)
例句:She talks about the ancient city as if she were there before.
与过去事实相反:从句用过去完成时
例句:He looks as if he had known the secret for a long time.
【方法归纳】
判断表语从句连接词时,先看从句是否缺成分:缺成分用连接代词/副词,不缺成分用 that/whether/as if 等。
遇到 reason 作主语时,直接锁定连接词 that。
表 “是否” 含义时,优先选择 whether,避免使用 if。
【易错提醒】
that 在表语从句中不可省略,即使从句成分完整、无实义。
连接代词 / 副词在从句中必须充当句子成分(主语、宾语、状语等),不可多余。
表语从句必须用陈述句语序,不可用疑问句语序。
错误:The problem is what is his real purpose.
正确:The problem is what his real purpose is.

The Importance of Critical Thinking in the Information AgeIn today's information age, we are surrounded by a vast amount of information from various sources such as the Internet, social media and traditional media. 1______ What we need is critical thinking, which enables us to distinguish between true and false information and make rational judgments.
Critical thinking is not about denying all information, but about analyzing and evaluating it objectively. 2______ For example, when we read a news report, we should not only accept the content at face value but also check the source of the information, the credibility of the author and whether there is sufficient evidence to support the views.
One of the key elements of critical thinking is the ability to ask questions. 3______ We should ask ourselves: Is the information consistent with known facts? Are there any logical flaws in the argument? What are the possible biases of the information provider? By asking these questions, we can deepen our understanding of the information and avoid being misled.
Another important aspect of critical thinking is the ability to consider different perspectives. 4______ We should try to understand the reasons behind different views and evaluate them comprehensively rather than sticking to our own opinions. This helps us form a more objective and comprehensive understanding of things.
The reason why critical thinking is so important in the information age is 5______ the spread of false information has become a serious problem. False information can mislead the public, affect social stability and even cause economic losses. Only by developing critical thinking can we effectively resist false information and make informed decisions.
In conclusion, critical thinking is an essential skill for everyone in the information age. It helps us navigate the complex information environment, make rational judgments and decisions, and ultimately promote personal and social development.
A.The question is how we can obtain useful information from it.
B. that we are often exposed to false and misleading information.
C. What matters is whether we can think independently and objectively.
D. It means we should not accept information passively but actively engage with it.
E. The key is that we should not only listen to one side of the story.
F. that it can help us solve all the problems we encounter in daily life.
G. Is the information we receive true and reliable?

2. 【答案】D
【解析】考查上下文衔接。前文解释批判性思维是客观分析和评估信息,而非否定所有信息,后文举例说明阅读新闻时应如何做,此处应进一步说明批判性思维意味着主动参与信息分析,而非被动接受。D 选项 “这意味着我们不应该被动接受信息,而应该主动参与其中” 符合语境。故选 D。
3.【答案】G
