delicious the soup tastes! I want to have more.

A.How a
B.What a
C.How
D.What

答案

19. C

解析

【分析】
要解决这道题,需明确英语感叹句中how和what引导的结构差异:how修饰形容词/副词,what修饰名词。本题中中心词是形容词delicious,后接主语the soup和谓语tastes,符合how引导的感叹句结构,无需加冠词,据此可判断答案。
【解析】
英语感叹句有两种核心结构:①what引导:What + (a/an) + 形容词 + 名词 + 主语 + 谓语!(名词为可数单数时加a/an,复数/不可数名词不加);②how引导:How + 形容词/副词 + 主语 + 谓语!本题中被感叹的部分是形容词delicious,并非名词,因此用how引导,且无需加冠词,对应选项C。
【答案】
C
【知识点】
感叹句的用法
【点评】
本题考查初中英语基础考点——感叹句的结构区分,需准确掌握how与what引导感叹句的不同规则,属于易得分的基础题。

hard-working students they are!

A.What
B.What a
C.How
D.How a

答案

20. A

解析

【分析】首先回忆英语感叹句的两种核心结构:What引导的感叹句修饰名词,How引导的感叹句修饰形容词或副词。解题时先确定句子的中心词,本题中心词是复数名词students,因此先锁定What引导的结构;再结合名词的数判断是否需要不定冠词,最终得出答案。
【解析】英语感叹句有两种常用结构:①What + (a/an) + 形容词 + 可数名词单数/不可数名词/复数名词 + 主语+谓语!;②How + 形容词/副词 + 主语+谓语!。本题中中心词是复数名词短语hard-working students,符合What引导的感叹句结构;由于students是复数名词,不能搭配不定冠词a/an,因此排除B、C、D选项,选A。
【答案】A
【知识点】感叹句的用法
【点评】本题考查感叹句引导词的辨析,需准确掌握What和How引导感叹句的结构差异,属于基础语法应用题目,注重对核心知识点的掌握。

Many people like cooking mashed potatoes at home. However, there's an important step where many of us go wrong. 1.
D
In fact, using different kinds of potatoes can make mashed potatoes taste and look great. Here are a few other mistakes to avoid(避免).
Cutting the potatoes into small pieces.
It's a good idea to cut large potatoes into big pieces. If you cut them smaller, they'll have too much water inside. After you cut the potatoes, place them into a pot with cold water, so they don't change colour. 2.
E
Remember to use low temperature to cook and cover the pot to cook them more quickly.
Boiling the potatoes and leaving them in the water for a long time.
The biggest mistake is boiling the potatoes and then putting them into a pot full of water for hours before cooking mashed potatoes. 3.
C
Instead, boil the potatoes until a small, sharp knife goes in easily. Then remove the water from the potatoes and keep the potatoes hot.
4.
A

When you've got hot potatoes, you're almost ready to mash. First, add butter and milk. Let them stay in the potatoes for three to five minutes. 5.
B
You'd better use a hand to mix them, which can let air go into the dish. Whatever you do, don't use a food blender.
