theyve been making tools， creating ceremonies， and sharing foodfor a long time. thats the conclusion of a recent study from south africas southern coast. there， in a cave lying above the sea， researchers from arizona state university have found evidence that humans were behaving in surprisingly complex ways as early as 164,000 years ago. our species， homo sapiens， appeared an estimated 200,000 years ago. the cave held three important clues about the behavior of these stone age people. first， the researchers found the remains of all kinds of shellfish. the people who lived in the cave probably collected these creatures from rocky shores and tide pools and brought them to the cave to eat. the researchers propose the early africans moved to the south african coast between 195,000 and 130,000 years ago. around that time， the climate inland turned relatively cold and dry. therefore， there were fewer plants and animals to eat away from the coast. when these ancient people moved to the coast， they probably experienced a major cultural shift， the researchers suspect. thats because observations of modern huntergatherer societies suggest that men are more likely to hunt for big animals when people live inland. on the coast， women play a more important role in providing food by gathering plants and shellfish. as for the second clue， the researchers unearthed 57 pieces of reddish pigment(颜料). the researchers think that the cave habitants used the paint for coloring their bodies or for other ceremonies. symbolic behavior is a clearly human feature. finally， the search discovered over 1,800 stone tools， including wellcrafted blades(刀片). these blades came in various sizes. the smallest were just less than a halfinch wide. ancient people may have attached these blades to the end of a stick to make spears or other tools. 16what is the passage mainly about？ aancient cave behavior. bnew evidence of ancient life. cthe history of human beings. dhuman behaviors

simple， and it works： drinking right amounts of water can really help you lose weight， new research shows. 2in what researchers claim is the firstever trial of the effect of water consumption on weight loss， scientists from virginia tech found that dieters who started each meal with two glasses of water lost nearly five pounds more， on average， than dieters who did not，over the course of 12 weeks. theres no shortage of clear evidence about how water might work to control your appetite (食欲). it _ so you dont eat so much； it keeps down your thirst so that you dont turn to calorierich sodas or juices. but until now， the researchers say， there has been no true evidence that waters appetitecontrolling benefits ever translate into actual weight loss. now there is. in the 12week study period， dieters instructed to drink water with every meal lost an average of 15.5 pounds； dieters given no instructions lost， on average， just 11 pounds. 3perhaps the most surprising thing about the finding is how little we still know about healthy water consumption in general. in fact， although doctors and public health authorities regularly remind us to drink more water， very few studies give any insight into what our ideal quantity may be. 4the new results today suggest that many people could indeed stand to drink a little more water than they do. but if youre looking to lose weight， be aware that it is actually possible to drink too much water， and you probably wont help matters any by drinking too much water at a time. in extreme cases， it can even be deadly. a couple of glasses with each meal， however， should be no problem at all for a healthy person.21what is the main idea of the text？(no more than 8 words)_22what might be able to control your appetite？ (no more than 3
