10、ne cells, grouped into phagocytes and lymphocytes. Phagocytes are a type of white blood cell. They are swimming around in your blood stream, always on the lookout for antigensthe pathogens that have entered your bodies. Whenever they see one, they will eat it.

11、 and kill. Then lymphocytes, which are also white blood cells and the main types are B cells, T helper cells and T killer cells, will be the killers of the sneaky antigens.B cells, T helper and T killer cells work together to find and kill these antigens.

12、s, which stick to the antigen. When that happens, it will tell the T helper cells to come over and either：1. help the B cells kill the antigen, or 2. call the phagocytes or T killer cells to move in for the kill. Once a B cell or a T cell attacks an antigen, they create cells to “remember” it. Those

13、 “memory cells” hang out in your blood and if they see the same antigen again, they quickly recognize it so your immune system can act faster at killing it.The immune system is more powerful than you probably imagine. Scientists from the University of Pennsylvania recently took immune cells from thr

The modified immune cells increased at least 1，000 times in the body and killed all the cancer cells. Therefore, more“memory cells”were

15、created.The immune system can be developed. Eating lean protein food（beef, beans） and food rich in vitamins A, C, and E（sweet potatoes, carrots）, taking a 30­minute walk every day and reducing your stress levels, etc. will help you achieve it. 1. What can the immune system do?A. Keep you from a

17、memory cells” to swim around in the blood.D. B cells produce antibodies to tell T helper and T killer cells.3. What does the underlined word “it” in the last paragraph refer to?A. The immune system can be made more powerful.B. Less antigens can be killed by the immune system.C. White blood cells act
