一、根据汉语、首字母提示及句意,填写所缺单词
1. These (药片) should be kept out of the reach of children.
2. If you are (不确定) about what to pick, click here.
3. How many (楼梯) are there up to the second floor?
4. I have such a poor that I have forgotten all about meeting you there.
5. The boy was enough to leave his keys in the car.

1. pills
2. unsure
3. stairs
4. memory
5. foolish

1. “药片”的英文是pill，是可数名词，前面有these修饰，表示这些药片，因此要用复数形式。
2. “不确定”的英文是unsure，在句子中作为表语。
3. “楼梯”的英文是stair，是可数名词，how many后接可数名词复数形式，询问数量。
4. 根据句意“我的记忆力很差，以至于我完全忘了在那里见过你”，结合首字母m，可以推断出应该填写memory，表示记忆力。
5. 根据句意“这个男孩太傻了，把钥匙忘在了车上”，结合首字母f，可以推断出应该填写foolish，表示愚蠢的。

二、用所给单词的适当形式填空
1. He found it impossible (make) her change her mind.
2. Could you give me some help? I really don't know what (talk) about.
3. Anna is too shy (speak) in public.
4. When I walked past the playground, I saw a group of boys (play) football.
5. You must remind him (take) his medicine, in case he forgets.

1. to make
2. to talk
3. to speak
4. playing
5. to take

1. 此题考查动词不定式作宾语的用法。在"find it+adj.+to do sth"结构中，it是形式宾语，真正的宾语是后面的动词不定式。因此，应填"to make"。
2. 此题考查"疑问词+不定式"的结构。在"don't know what ______ (talk) about"中，需要用"疑问词what+不定式"来作宾语，表示"不知道谈论什么"。因此，应填"to talk"。
3. 此题考查"too...to..."结构。在"Anna is too shy ______ (speak) in public"中，"too...to..."结构表示"太……而不能……"，所以应填"to speak"。
4. 此题考查"see sb doing sth"结构。在"I saw a group of boys ______ (play) football"中，"see sb doing sth"表示"看见某人正在做某事"，因此应填"playing"。
5. 此题考查"remind sb to do sth"结构。在"You must remind him ______ (take) his medicine"中，"remind sb to do sth"表示"提醒某人做某事"，所以应填"to take"。

三、短文填空：阅读下面短文,在空白处填入一个适当的单词或用括号内单词的正确形式填空

Andrew Cooper, who leads the program the robot can help scientists and free up time for the human researchers to think (10) (creative).

its; similar; easily; itself; direction; To test; did; according; months; creatively

1. 考查固定搭配"on one's own"，主语是robot，用its，填its。
2. 考查固定搭配"be similar to"，表示"与……相似"，填similar。
3. 副词修饰动词move，easy的副词是easily，填easily。
4. 反身代词作宾语，主语是robot，填itself。

9. several后接名词复数，month的复数是months，填months。
10. 副词修饰动词think，creative的副词是creatively，填creatively。

四、同义句转换
1. I found that they were painting the house.
I the house.
2. The problem is so difficult that I can't work it out.
The problem is so for me .
3. She spoke so clearly that everyone could hear her.
She spoke for everyone .
4. They are talking about how they should deal with the problem.
They are talking about with the problem.
5. Sandy practices hard every day in order to improve her skills.
Sandy practices hard every day improve her skills.

1. found them painting 2. difficult; to work out 3. clearly enough; to hear 4. how to deal 5. so that she can

1. 原句是“find + that从句”结构，可转换为“find sb. doing sth.”，they变为宾格them，所以填found them painting。
2. “so...that...”（如此……以至于……）可转换为“too...to...”（太……而不能……），“work it out”保持不变，所以填difficult; to work out。
3. “so...that...”结构，此处“clearly”是副词，转换为“+形容词/副词+enough for sb. to do sth.”，所以填clearly enough; to hear。
4. “how they should deal with”可转换为“how to deal with”，所以填how to deal。
5. “in order to”（为了）可转换为“so that + 从句”，主语是Sandy，从句用she can，所以填so that she can。
