       3 . The cup lid assembly as claimed in  claim 1 , wherein a cover receiving portion is provided along the outer rim of the cup receiving body, whereas at least one cover joining portion is provided corresponding to the cover receiving portion for pivotal joining, and through the pivotal connection between the cover joining portion and the cover receiving portion, the covering lid can be turned when it is placed on the cup receiving body.  
   
   
       4 . The cup lid assembly as claimed in  claim 3 , wherein the cover receiving portion is formed in a way that its center is a hole.  
   
   
       5 . The cup lid assembly as claimed in  claim 1 , wherein a first recess is provided at the edge of the liquid discharge opening on the cup receiving body, a big plug made of flexible material is sleeved on the anti-liquid-flow portion on the drive sheet, wherein a first protrusion is provided on the big plug to be corresponding to the first recess, and through joining made between the first protrusion and the first recess, the liquid discharge opening can be entirely sealed.  
   
   
       6 . The cup lid assembly as claimed in  claim 1 , wherein a second recess is provided at the edge of the vent on the cup receiving body; besides, a small plug made of flexible material is sleeved on the anti-air-flow portion, wherein a second protrusion is provided on the small plug to be corresponding to the second recess, and through joining made between the second protrusion and the second recess, the vent can be entirely sealed.  
   
   
       7 . A cup lid assembly, provided at the brim of a cup body to be turned by opening and closing operation, including 
 a cup receiving body, to cover the brim of a cup, wherein a liquid discharge opening and a vent are provided penetrating through the cup receiving body; besides, a push block and a halt block are separately provided, extending from the cup receiving body thereon, and located at each side of an imaginary line drawing along the liquid discharge opening and the elastic body; also, an accommodation slot is concavely provided in an upward direction in the middle of the cup receiving body;    a covering lid, which is pivotally connected to the rim of the cup receiving body and can be turned by turning operation when it is placed on top of the cup receiving body; a drinking opening is provided penetrating through the covering lid, capable of corresponding to the liquid discharge opening when the drinking opening is turned by turning operation made on the cup receiving body; an axle is provided extending from the bottom of the covering lid, and an elastic body is provided in the axle; taking the axle as a dividing line, two guide portions are symmetrically provided at two sides of the dividing line, and a releasing slot and a press-against section are located on each guide portion respectively, wherein the releasing slot is connected to one end of the press-against section and forms an arch-shaped angle, and an actuating block is located at the other end of the releasing slot whereas a hinder block is located at the other end of the press-against section; and    a drive sheet, wherein an anti-liquid-flow portion and an anti-air-flow portion are provided extending from the drive sheet thereon, corresponding to the positions where the liquid discharge opening and the vent are located respectively; also, a pivot-connecting portion is provided extending from the middle of the drive sheet, to be pivotally connected to the axle as well as to be pulled by the elastic body for leaning closely to the covering lid; in addition, when the drive sheet is moving downward, the accommodation slot can accommodate the pivot-connecting portion;    to operate, when the drive sheet located in the press-against section makes a position-shift downwardly to press against the elastic body, the anti-liquid-flow portion can be tightly plugged into the liquid discharge opening whereas the anti-air-flow portion can be tightly plugged into the vent; in contrast, when the drive sheet is pulled back to the releasing slot by the elastic body, the anti-liquid-flow portion and the anti-air-flow portion can be detached from the liquid discharge opening and the vent respectively; thus, the brim of the cup can be turned opening and closing.
