我们应该捡起这些垃圾!?pick up 动词短语，意为“拾起，捡起”，如果宾语是代词，应放于中间。例如：?He picked up a piece of paper and put it into the dustbin.
他捡起一张纸把它放在垃圾箱里。和pick up 结构相同的短语很多。例如：put on（穿上），take off（脱掉），turn off（关上），turn on（打开），
put away（收拾好），look up（查阅），try on （试穿）等，代词作宾语时放中间，名词作宾语放中间放后面均可。3. Each student could clean up a bit of the schoolyard. 每个学生能清理一块儿校园。?each 形容词，两者或两者以上的每一个，后加单数名词。

在大街两侧你可以看见花。?a bit of “一点儿，一些”，修饰不可数名词时，相当于a little。但a little 后不加of。例如：I know a bit of (a little) English. 我懂一点英语。另外，a bit 修饰形容词或副词，相当于a little。例如：It’s a bit cold today. 今天有点冷。4. Jenny explains the plan to the class.

explain的用法。explain作动词, 意为“解释”; 常用搭配: explain sth. to sb. 意为“向某人解释某事”, 这个结构还可以表达为explain to sb. sth. , 但是不能表达为explain sb. Sth. 。因为explain不是双宾语动词, 其后不能直接跟双宾语, 只有双宾语动词才能进行间接宾语和直接宾语的同义句转换。例如：
Please explian to me the meaning of the word. = Please explian the meaning of the word to me.
