         8 . The cup sleeve of  claim 1 , wherein said top portion of said sleeve body is formed with a top open end, and an indented edge that extends downwardly from said top open end and that corresponds in position to a liquid outlet of the cup lid. 
     
     
         9 . The cup sleeve of  claim 1 , wherein said sleeve body further includes a pair of diametrically opposite position members formed on said surrounding wall below said lid engaging unit, said cup sleeve further comprising a gripping member connected to said position members. 
     
     
         10 . The cup sleeve of  claim 9 , wherein said position members are configured as apertures, said gripping member including a gripping strap with two opposite ends, each of which has a pivotal latch member that is engageable with a respective one of said apertures when said two opposite ends respectively pass through said apertures. 
     
     
         11 . The cup sleeve of  claim 1 , wherein said top portion of said sleeve body has a top open end, and a gripping portion that is formed integrally with said surrounding wall at said top open end. 
     
     
         12 . The cup sleeve of  claim 11 , wherein said top open end  61  of said sleeve body has an annular thickened edge formed on top of said surrounding wall, two diametrically opposite pivot parts formed in said surrounding wall beneath said annular thickened edge, and a tearing line that is formed in said surrounding wall and that is connected between and extends downward from said pivot parts, wherein, when a part of said thickened edge above said tearing line is pulled upward, said part together with said gripping portion is separated from said surrounding wall to form said gripping member. 
     
     
         13 . The cup sleeve of  claim 12 , wherein said top open end  61  further has an indented edge part  611  that is formed along said tearing line after said part of said thickened edge is separated from said surrounding wall, and said top portion of said sleeve body further has two pivot holes, each of which is formed at a connection of one of said pivot parts and said surrounding wall. 
     
     
         14 . The cup sleeve of  claim 11 , wherein said top portion of said sleeve body has a non-indented top edge, an indented top edge  611  that extends downwardly from said non-indented top edge toward said bottom portion and that corresponds in position to a liquid outlet of the lid, and a protruding portion protruding upwardly from said non-indented top edge to form said gripping member and having a gripping hole. 
     
     
         15 . A cup assembly, comprising
 a cup lid having a cup surrounding portion formed with a clipping groove, and a sleeve engaging member extending from said cup surrounding portion;   a cup having an upper portion formed with a top flange and an open end surrounded by said top flange, and a lower portion opposite to said upper portion; and   a cup sleeve detachably engaged with said cup lid and sleeved around said cup, said cup sleeve including a sleeve body formed with a receiving space for receiving said cup, and including a bottom portion, a top portion that is opposite to said bottom portion, a surrounding wall that extends from said bottom portion to said top portion, and a lid engaging unit that is formed on said surrounding wall and that is proximal to said top portion;   wherein said top flange of said cup is clamped in said clipping groove of said cup lid, said lid engaging unit being engaged with said sleeve engaging member of said cup lid, said sleeve body cooperating with said cup to form a heat insulating gap therebetween.
