一、判断下列句子属于方框中所列的哪种基本句型， 并将正确答案的字母代号填入题前括号内。

()1. I bought my sister a new pen.
()2. The computer broke down.
()3. There is a lot of information online.
()4. They built a new bridge.
()5. He looks happy today.
()6. The app can help us learn English.

1.D 2.A 3.F 4.C 5.B 6.E

我们逐个分析每个句子的结构：
1. 句子"I bought my sister a new pen"中，I是主语，bought是谓语，my sister是间接宾语，a new pen是直接宾语，属于S+V+O+O结构，对应选项D。
2. 句子"The computer broke down"中，The computer是主语，broke down是不及物动词短语作谓语，没有后续宾语等成分，属于S+V结构，对应选项A。
3. 句子"There is a lot of information online"以There is开头，完全符合There be句型的特征，对应选项F。
4. 句子"They built a new bridge"中，They是主语，built是谓语，a new bridge是动作的承受者作宾语，属于S+V+O结构，对应选项C。
5. 句子"He looks happy today"中，He是主语，looks是系动词，happy是形容词作表语，属于S+V+P结构，对应选项B。
6. 句子"The app can help us learn English"中，The app是主语，can help是谓语，us是宾语，learn English补充说明us的动作，作宾语补足语，属于S+V+O+C结构，对应选项E。

二、根据要求完成下列各题，每空一词。
1. The dog is sleeping under the tree.（改为否定句）
The dog under the tree.
2. My mother cooked a delicious meal for us.（改为同义句）
My mother cooked .
3. She often helps her mother with housework.（改为一般疑问句）
her mother with housework?
4. Tom runs the fastest in his team.（对画线部分提问）
the fastest in his team?
5. There were twelve girls playing sports in the gym at three o'clock yesterday afternoon.（对画线部分提问）
playing sports in the gym at three o'clock yesterday afternoon?

1. is not sleeping
2. us a delicious meal
3. Does she often help
4. Who runs
5. How many girls were there

1. 现在进行时变否定句，直接在be动词后加not，后续现在分词形式保持不变，题目要求每空一词共填3个词，因此对应填入正确形式。
2. 考察双宾语固定搭配转换：cook sth. for sb. 和cook sb. sth. 含义完全相同，按照4个空的要求转换即可。
3. 一般现在时主语为第三人称单数she，变一般疑问句需将助动词Does置于句首，后续谓语动词变回原形，频度副词often放在主语和实义动词之间，按4个空的要求组合即可。
4. 画线部分Tom是指代人的句子主语，对人提问用特殊疑问词Who，原句谓语是第三人称单数形式runs，无需调整剩余部分语序，按2个空的要求填写即可。
5. 画线部分twelve是可数名词girls的数量，提问可数名词数量用How many，原句为there be句型，按5个空的要求调整结构即可。

一、根据汉语意思翻译下列句子，每空一词。
1. ——王强认为互联网怎么样？
——他认为它非常有用。他可以找到任何他想要的东西。
—What Wang Qiang the internet?
—He thinks it's very . He can find he wants.
2. 或许你的电脑出了问题。你最好找人来帮你检查一下。
Maybe there is your computer. You'd better ask someone to for you.
3. 互联网既有优点也有缺点。
The internet has both and .
4. 随着电脑技术的发展，电脑不仅变得越小、越轻，而且更加强大。
With the development of computer technology, computers became and , more .
5. 互联网很棒，它为我们打开了一扇通往新世界的大门。
The internet is very wonderful, and it the door for us.

1. does; think; of; useful; anything/everything
2. something wrong with; check it over
3. advantages; disadvantages
4. not only smaller; lighter; but also; powerful
5. opens; to the new world

1. 第1小题考查询问他人对事物看法的固定句型"What do/does sb. think of..."，主语Wang Qiang是第三人称单数，助动词用does，后接动词原形think，搭配介词of；“有用的”对应形容词useful；“任何他想要的东西”可用anything/everything表达，符合语境。
2. 第2小题考查固定表达"there is something wrong with..."，意为“……出问题/有故障”；表示“检查”的短语是check over，代词it指代电脑需要放在短语中间，构成check it over。
3. 第3小题考查可数名词的复数形式，“优点”对应advantage，“缺点”对应disadvantage，both后接可数名词复数，因此变形为advantages和disadvantages。
4. 第4小题考查形容词比较级和固定结构"not only...but also..."，“更小”的比较级是smaller，“更轻”的比较级是lighter，“不仅……而且……”对应not only和but also，“更强大”是more powerful，符合句意。
5. 第5小题考查一般现在时和固定搭配"open the door to..."，主语it是第三人称单数，谓语动词用opens，“通往新世界”对应to the new world。
