()1. —How can you play the piano so well?
—My mom me to practice when I was very young.

A.led
B.achieved
C.helped
D.encouraged

D

根据固定搭配“encourage sb to do sth”（鼓励某人做某事），结合语境，妈妈在我小时候鼓励我练习钢琴，符合句意。A选项led（带领）、B选项achieved（实现）、C选项helped（帮助，常用help sb (to) do sth）均不符合此处结构和语境，故选D。

()2. —I thought you would arrive on time!
—So I made a mistake! Nobody's .

A.right
B.lucky
C.perfect
D.wrong

C

根据对话语境，答句提到“我犯了错”，此处需表达“没有人是完美的”这一含义，结合选项，A意为“正确的”，B意为“幸运的”，C意为“完美的”，D意为“错误的”，故答案为C。

()3. —Do you think Tina has a lot in math?
—Yes. She got an A in the math test again this week.

A.changed
B.progressed
C.communicated
D.competed

B

根据答语“She got an A in the math test again this week.”可知，问句询问Tina在数学方面是否进步了很多。progressed意为“进步”，符合语境；changed（改变）、communicated（交流）、competed（竞争）均不符合。

()4. —Let's the tent and then we can sleep in it.
—No problem.

A.put on
B.look up
C.put up
D.run out

C

Let's后接动词原形，结合语境“然后我们可以睡在里面”，搭帐篷用put up，A put on（穿上）、B look up（查阅）、D run out（用完）均不符合，故选C。

()5. —Lily, do you like model cars?
—Harry, it's not my cup of tea.

A.collecting
B.introducing
C.driving
D.comparing

A

like doing sth是固定搭配，意为喜欢做某事；collecting model cars意为收集模型车，符合语境，其他选项不符合句意，因此选A。
