当堂达标（见导学案“当堂达标”）

答案与解析：

Ⅰ. 1. D

yogurt是不可数名词，没有复数形式，也不能用how many提问，故排除A、C两项；不可数名词前通常用“表示量的名词+of”来表示数量，就不可数名词前“表示量的名词”进行提问时要用how many，故选D。

2. C

bread是不可数名词，“一片面包”为a piece of bread，“两片面包”为two pieces of bread。

3. D

hope意为“希望”，后可跟that引导的宾语从句；let，make后不能跟宾语从句。C项

形式不对。

4. A

句意：你怎样制作香蕉奶昔? 5. C

句意：请不要开窗。我有点儿冷。open作动词时，意为“打开”，其反义词是close（关上）；祈使句的否定形式是在谓语动词前直接加don’t。由句意可知选C。

6. C

祈使句的否定形式是在谓语动词前直接加don’t。

Ⅱ. 1. snows

时态承接上文，用一般现在时；主语是it，所以谓语动词应用第三人称单数形式。

2. impossible

句意：在冬天不可能得到各种新鲜的蔬菜。

3. found

in the old days意为“从前；过去的时候”，由此可知本句应用一般过去时；find的过去式为found。

4. mixed

承接上文时态，要用一般过去时。

5. scientists

scientist意为“科学家”，是可数名词；some后跟可数名词复数形式。

6. health

名词所有格修饰名词或名词短语；people’s health 意为“人们的健康”。

7. disagree

由But可知下文的观点与上文观点相反。故填disagree。句意为“有些人不同意（上文的观点）”。
