例题1
:(山西中考)The temperature in the fresh - keeping area can be different from shelf to shelf. The higher the shelf is, the higher the temperature will be. 2.
A
If you store it on the right shelf, you can get the best out of your food.
A. So make use of these different temperatures.
B. The freezer temperature should be below $- 18° C$.
C. It's necessary to know where to put your fridge.
D. Bottom shelves are the coldest part of the fridge.
E. The tips above can help you keep your food fresh.
F. Let's learn how to store food correctly in the fridge.

答案

2. A 解析:A 根据上文“The temperature in the fresh - keeping area can be different from shelf to shelf.”可知冰箱搁板之间的温度是不同的,因此要利用不同的温度来储存不同的食物;此处与上文是因果关系。

解析

【分析】
本题为英语七选五题型,解题关键是梳理空格前后的逻辑关系。上文说明冰箱保鲜区每层搁板温度不同(越高温度越高),空格后指出“放对搁板能最大化利用食物”,因此空格处需承接“温度不同”的特点,引出“利用不同温度”的结论,形成因果关联,据此筛选选项。
【解析】
1. 先分析上文核心信息:冰箱保鲜区各搁板温度存在差异,高度越高温度越高;
2. 再分析空格后内容:放对搁板可让食物发挥最佳效果;
3. 逐一排查选项:A选项“所以要利用这些不同的温度”,既承接上文“温度不同”的特点,又与后文“放对搁板”形成因果逻辑,符合语境;B选项讲冷冻室温度,与上下文无关;C选项“知道食物放冰箱哪里”表述宽泛;D选项提及底层温度,上文未涉及;E选项“上述技巧保鲜”,上下文未提技巧;F选项“学习正确储存方法”过于笼统。因此选A。
【答案】A
【知识点】英语七选五、上下文逻辑推理
【点评】本题考查七选五题型中因果逻辑的判断,需准确把握前后文关联,是中考常见的语篇衔接类题目,难度适中。

:(朝阳中考)It is a joy to watch a skilled hand use an abacus(算盘). Fingers move, beads(珠子)knock, and after a few seconds, the result comes out. 3.
F
So it was taught in many schools. Wherever there was a need for calculations(计算), an abacus would come into sight.
A. Many young people have not even heard of the word “abacus”.
B. So the abacus is a symbol of wealth for traders in China.
C. It shows the great wisdom of the ancient Chinese people.
D. The abacus is usually made of wood.
E. It has been around for over 5,000 years.
F. In the past, the use of the abacus was a necessary skill.
G. More and more people are using abacuses nowadays.

答案

3. F 根据下文“So it was taught in many schools.”可知很多学校都教使用算盘,因为这是有用的技能;F项“在过去,使用算盘是一项必要的技能。”与下文是因果关系,前因后果。

解析

【分析】本题为英语七选五题型,解题思路是:先定位空格位置(段中),再分析空格前后的逻辑关系——空格后有因果连词“so”,说明空格内容是“学校教算盘”的原因,需找能构成因果关系的选项,结合选项含义匹配即可。
【解析】空格后“so it was taught in many schools”表结果,说明空格处是原因。选项F“在过去,使用算盘是一项必要的技能”,正好解释了“学校教算盘”的原因,构成前因后果的逻辑关系。其他选项:A(年轻人没听过)与后文学校教矛盾;B(商人财富象征)、C(古代智慧)、D(材质)、E(存在时长)、G(现在用的人多)均无法与后文形成因果衔接,故排除,选F。
【答案】F
【知识点】七选五阅读、逻辑推理
【点评】本题考查七选五阅读中因果逻辑的运用,需抓住空格后的“so”这一关键衔接词推导原因,难度中等,是中考常见题型。
【难度系数】0.5
例题2
:(辽宁中考)Clouds are always changing. They form and then change into gas soon. They are changing shapes as the wind blows them across the sky. Will the shapes stay long? 4.
C
But some small soft clouds often last 10 minutes.
A. Clouds are heavy.
B. Clouds look like elephants.
C. Some big clouds can hang around all day.
D. The following can help you know more about them.
E. Most of the insects inside clouds are blown there by the wind.

答案

4. C 解析:C 根据下文“But some small soft clouds often last 10 minutes.”可知一些小块的云的形状通常保持10分钟,而一些大块的云可以保持一整天;此处与下文是转折关系。

解析

【分析】
本题为英语补全对话类题目,解题时需先通读上下文明确语境与逻辑关系。空格后由转折连词but引出“一些小的软云通常持续10分钟”,说明空格处应填与“小云朵持续时间”形成对比的内容,结合选项匹配即可得出答案。
【解析】
根据空格后的转折句“But some small soft clouds often last 10 minutes.”可知,此处需填写与“小云朵持续时间”形成对比的内容。选项中C项“Some big clouds can hang around all day.”(一些大云可以持续一整天)符合语境,与后文形成转折对比,故选C。
【答案】C
【知识点】英语补全对话、上下文逻辑推理
【点评】本题考查对英语补全对话中上下文逻辑关系的理解,通过转折连词的提示,结合前后文内容对比即可选出正确选项,难度适中。
【难度系数】0.6
