The immune system (免疫系统) is the bodys defence (防卫) system that protects you from illness and disease caused by the pathogens.The immune system is made up of non-specialized defences such as skin, tears and the acidic juice produced by the stomach, keeping you from the pathogens. It also has some highly specialized defences, which are different kinds of immune cells (细胞), grouped into phagocytes (噬菌细胞) and lymphocytes (淋巴细胞). Phagocytes are a type of white blood cell. They are swimming around in your blood stream, always on the lookout for antigens (抗原) the pathogens that have entered your bodies. Whenever they see one, they will eat it. However, some antigens are hard to find 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. B cells produce substances, called antibodies, 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 “memory cells” hang out in your blood and if they see the same antigen again, they quickly recognize (识别) 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 three patients with leukemia (白血病), then genetically changed them into “serial killer” cells to attack cancer cells. The study was small but the results were ground-breaking. The modified immune cells increased at least 1,000 times in the body and killed all the cancer cells. Therefore, more “memory cells” were 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 30-minute walk every day and reducing your stress levels, will help you achieve it.21 . The immune system can _.Akeep you from antibodies.Bprotect you against antigens.Cmake your bodies weak and sick.Dhelp microbes enter your bodies.22 . How are the sneaky antigens found and killedAB cells produce antibodies to tell T helper and T killer cells.BB cells create “memory cells” to swim around in the blood.CSkin, tears, acidic juice and immune cells work together.DPhagocytes, B cells, T helper and T killer cells work together.23 . After a B cell or a T cell attacks an antigen, they create _.AphagocytesBlymphocytesCmemory cellsDserial killer24 . The underlined word “it” in the last paragraph refers to _.ALess antigens can be killed by the immune systemBThe immune system can be changed into the “serial killer”CWhite blood cells act less quickly in the immune systemDThe immune system can be made more powerful25 .

The best title(标题) for this passage is “”ADiscovering DinosaursBAsking Good QuestionsCFinding SubjectsDLearning StepsFresh green grass, hundreds of colorful wild flowers, water running into little pools, birds making their homes in boxes, the 9,500-square-meter Augustenborg Botanical Garden may look just like any other well-organized park, but theres a difference. It lies on the roofs (屋顶) of industrial and office buildings in the city of Malmo in Sweden.Green roofs are not a new invention. And now they are getting popular again. The common roofs of a modern city have endless black surfaces with no life or water. Perhaps thats why a garden on a roof becomes such a perfect choice for more and more people.Green roofs are not just pretty. They also help to moderate the city temperature. The high temperatures on common roofs in the summer can make top floor flats uncomfortably hot. What is more, they play a part in making the cities hotter than the countryside around them, causing the “urban heat-island effect”. On a green roof, however, with its plants and water, temperatures change only a little, as they do in a park. Rooftops covered with plants help keep buildings cool. Green roofs take in rain water and protect the city drainage (排水) system. They can reduce water runoff into streets and storm water systems. This can greatly cut the costs of heating and cooling in the building below.Also, _. Small animals and birds can make their homes on it. Thanks to this, the city may become part of nature, rather than something completely separate from it. Though they wont directly replace ground environments, theyre perfect for attracting birds and other wildlife to create a eco-friendly habitat (栖息地).A green roof helps to improve the overall air quality, too. According to a study, green roofs help reduce (减少) up to:37% of sulfur dioxide21% of nitrous acid0.2kg of dust particles / square meter each yearWhile the cost of building such a roof can still be higher, it can be cheaper in the long term as a result of energy savings. And wouldnt it be wonderful to be able to walk out into a garden high above the citys noise and traffic, whether youre at school or in an office or just at home in a ten-floor block?30 . With the example of Augustenborg Botanical Garden, the writer wants to explain _.Ahow wildlife is protectedBwhat a green roof is likeChow to organize a good parkDwhat to do with a spare roof31 . The word “moderate” in Paragraph 3 probably means “_”.AraiseBcheckCrecordDcontrol32 .
