如何保持平衡how to keep balance
因为是去学,肯定是学如何做这件事.
B句意不完整
第三次改……五花八门的答案……偶决定要去问老师……
D 翻译一下
B
翻译：如果你想学习滑冰，最重要的事情是你要学会保持平衡
to do sth
选B
先排除D
keep balance是保持平衡的意思
选 B
to do something
经典不定式用法
D 不对， 如果用D，需要改成： to know how to keep balance
这是从中国语法角度解释， 希望有帮助
D
B
IS后接不定式.
D不完整.应改为to know how to keep balance
选B
be to do sth 是动词不定式
keep balance是习惯用语，保持平衡的意思
C改成 to be balanced就对了
D是典型的Chinglish,语义重复，句子可改成 you need to learn how to keep balance
D；
选B 用不定式 to do sth，keep后面加动词原型。故选B
D how to keep balance 缺少谓语。
