1、Whose baseball glove is it 这是谁的棒球手套？
【详解】 whose 是who的所有格形式，用来询问东西是谁的。
句子的基本结构为：Whose +名词+be动词+代词？
其回答为：It’s/They’re +物主代词/名词所有格+名词。如：
例如： Whose bike is this — It’s his bike.
这是谁的自行车？一是他的自行车。
Whose books are they They’re Helen's (books).它们是谁的书？ 一它们是海伦的(书)。
【拓展】
who与whose都是疑问代词，用来构成特殊疑问句。特殊疑问句不能用yes和no来回答，要用完整形式来回答，读时用降调。
①who的意思是“谁”，问的是姓名或某人的关系。
如：—Who is he —He is John ．（问姓名） 他是谁？他是约翰。
—Who is she —She is our teacher．（问关系） 她是谁？她是我们的老师。
当用who提问，不知道是谁和人的数量时，问句的谓语动词常用单数。
如： Who isn't at school today？ 今天谁没到校？
②whose一般是就物主代词或名词所有格提问。
1）提问部分作定语时，用“Whose ＋名词＋一般疑问句？”结构。
如： It's my shirt．→Whose shirt is it？ 这是我的衬衫。→这是谁的衬衫？
2）提问部分作表语时，用“Whose ＋一般疑问句？”结构。
如： The shirt is mine． →Whose is the shirt？ 这件衬衫是我的。→这件衬衫是谁的？
2、Yes, twice a week, and sometimes more! 是的，一周两次，有时候更多。
【详解1】 twice 用作副词，表示次数，意为 “两次；两倍”。次数的表达如下：
次数的表达 总结：表达次数很容易，once，twice单独记，三次以上有规律，基数词后加times就可以。
once 一次 twice 两次 three times 三次
【拓展】固定搭配：
at once 立即，马上 once again 再一次 once in a while 偶尔地；有时
once upon a time 从前 think twice 再三考虑
3、Who does this T-shirt belong to 这件T恤是谁的？
【详解】 belong to表示“属于; 是..的成员”, 后面接名词或代词宾格作宾语, 不可用于被动语态和进行时态。
“belong to+人” 相当于 “be+名词所有格/名词性物主代词”。
例句：That pen belongs to me.= That pen is mine. 那支钢笔是我的。
many times 很多次
几次到几次 … to … 如：three tofour times三到四次 几次或几次 …or…如：three orfour times三次或四次 每天…次：次数+ a day每天一次：once a day每周…次：次数+ a week每周两次：twice a week每月…次：次数+ a month 每月四次：four times a month每年…次：次数+ a year每年十次：ten times a year
【拓展】 belong不与to连用时, 后面通常跟的是副词或其他介词短语，表示“应当在(某处),适合在(某处)”。
例句： That table belongs in the other room. 那张桌子是另外那个房间的。
4. My skateboard is really cool, and so are theirs. 我的滑板真的很酷，他们的（滑板）也很酷。
so + 助动词(情态动词/连系动词) + 主语：表示前面所说的肯定情况也适用于后面的人或事物，意为“……也一样”。 theirs 是名物代，相当于 their skateboards，在句中作主语。
例句：
①I am good at playing basketball, and so is my brother.
我擅长打篮球，我的弟弟也擅长。
②We like reading books, and so do they.
我们喜欢读书，他们也喜欢。
③She can swim very well, and so can her sister.
她游泳游得很好，她的姐姐也游得很好。
5、How often do you do sport or exercise 你多久运动或者锻炼一次？
【详解1】 how often表示“多久一次”。用来询问动作的频率。
其答语通常是once a day, often, usually, every day, never, sometimes, three times a week等。
例句： ---How often does he eat vegetables 他多长时间吃一次蔬菜？
---Every day.每天。
【拓展】特殊疑问句中与how相关的疑问词组用法
词组 词义 用法 答语特征
how long 多久 询问时间多长 for/about＋一段时间
how often 多久一次 询问动作的频率 often， twice a week等
how soon 过多久以后 询问时间多久（用于一般将来时） in＋一段时间
how far 多远 询问距离多远 ten minutes’ walk
how many 多少 询问可数名词数量 数词＋可数名词复数
how much 多少 询问不可数名词数量 数词＋表示量的词＋of＋不可数名词
多少钱 询问价格 数词＋货币单位
6. Some tricks are difficult, but once you succeed, you feel great! 一些（滑板）技巧很难，但一旦你成功做到了，你就会感觉棒极了！
once 在这里用作连词，意为“一旦；一……就……”，引导条件状语从句。在条件状语从句中，通常用一般现在时表示将来的情况。
例句：
①Once you make a promise, you should keep it.
一旦你许下诺言，就应该遵守它。
②Once he starts working, he won't stop easily.
一旦他开始工作，就不会轻易停下来。
③Once the rain stops, we will go out for a walk.
一旦雨停了，我们就会出去散步。
本句中的succeed是动词，常用搭配为：succeed in doing sth. 成功做某事
它的名词为success；形容词为successful，副词successfully。
