不可数名词"锻炼，运动"

频率副词hardly
Hardly意为"几乎不，几乎没有"，是否定意义的副词，相当于almost not，句中不能出现类似no,not,never等表示否定意义的词。
Linda, pass me my glasses,please.I can hardly read the words in the newspaper.
琳达，请把我的眼镜递给我。我几乎看不见报纸上的字。
【区别】hardly与hard
① hardly不是hard加后辍所构成的，它是副词，常与can或any连用。
② hard可用作形容词，意思为"艰难的，困难的，勤奋的"可等同于"difficult"。它也可用作副词，意思是"努力地，刻苦地，猛烈地"。
There were hardly any people living there.几乎没有人生活在那里。

Full adj. 此处意为忙的，还可意为"满的，充满的"与"饱的，完全的"。

辨析：be full of 和be filled with
be full of 装满；充满（表示状态）
be filled with装满；充满（表示动作，为fill...with的被动形式）
fill...with把...装满充满
Then ,in came a truck full of sand. 接下来，进来了一辆装满沙子的卡车。
考点3 She sometimes goes shopping.她有时购物。

some times是名词短语，意思是"几次；几倍"。
