【拓展】(2023全国高考阅读D篇)
On March 7, 1907, the English statistician Francis Galton published a paper which illustrated what has come to be known as the “wisdom of crowds” effect. The experiment of estimation he conducted showed that in some cases, the average of a large number of independent estimates could be quite accurate.
This effect capitalizes on the fact that when people make errors, those errors aren’t always the same. Some people will tend to overestimate, and some to underestimate. When enough of these errors are averaged together, they cancel each other out, resulting in a more accurate estimate. If people are similar and tend to make the same errors, then their errors won’t cancel each other out. In more technical terms, the wisdom of crowds requires that people’s estimates be independent. If for whatever reasons, people’s errors become correlated or dependent, the accuracy of the estimate will go down.
Q: What can we infer from the two paragraphs
A. More accuracy requires independent estimates.
B. The same mistakes can cancel each other.
C. Different people make different errors.
D. “Wisdom of crowds” effect relies on people’s errors.

Why Organic Farming Deserves Support
In my opinion, organic farming is a better choice for long-term agricultural development.
matters most is protecting food safety and the environment. Organic farmers avoid artificial chemicals and use natural methods to enrich the soil. Therefore, crops are safer, and soil and water suffer less pollution.
Therefore, we should promote organic methods while using science to improve their output. A gradual and practical transition can protect nature and meet people's needs.

Key Point 1
连接词选择：先看从句是否缺少成分
基本结构
Yuan Longping cared about was not money.
That hybrid rice raised output changed farming.
从句缺成分
what/who/which既连接从句，又在从句中作主语、宾语或表语。
从句不缺成分
that只连接、不作成分；whether表示“是否”。
判断要点
先检查从句主干是否完整，再根据句意选择连接词。
UNIT 5
Key Point 2
陈述语序与形式主语it
陈述语序
How farmers can boost yields remains important.
连接词+主语+谓语
不写how can farmers
形式主语it
It is estimated that...
It is important that...
it放句首保持平衡
that从句是真正主语
判断关键
主语从句较长时，常用it作形式主语。
It + be +形容词/过去分词/名词+ that从句。
