In the future, robots like Robonaut, a humanoid, invented by NASA, will be doing dangerous jobs, like repairing space stations They will also be doing more and more of the household work for us In Japan, on the other hand, where humanoid robots are appearing faster than in America, the Japanese are designing androids that will entertain us by dancing and playing the piano Some people worry that the future holds: will we have created another Frankenstein’s monster? What’s more worrying is whether people themselves are becoming increasingly like robots Experts predict that more and more people will be wearing micro-computers, connected to the Internet, in the future People will have micro-chips in various parts of their body, which will connect them to a wide variety of gadgets Perhaps, we should not exaggerate the importance of technology, but one wonders whether, in years to come, we will still be falling in love and whether we will still feel pain Who know? There will be robots that can dance and playing the piano in Japan The Massachusetts Institute of Technology invented a robot that imitates the actions of a mother.TRUE FALSE Kismet is different from other robots because A A B TRUE B FALSE It thinks for itself C It can walk and speak It is not like science fiction D It seems to have feelings B What makes Cog special? A B D agree It looks like another C It does things a mother does It has a human brain D It behaves like a child In 2020 years ' time robots will A B Behave like animals C Look like humans Be able to express ideas D Think like humans In the future, robots will A Entertain people C Move much faster Explore space D Do all of the housework Our oceans are becoming (1) polluted Most of this pollution comes (2) the land, which (3) it comes from people Firstly, there is raw sewage, which is pumped directly into the sea Many countries, (4) developed and developing, are guilty of doing this Secondly, ships drop MC LC A M U Trang I Lý chn ti II Mc ớch nghiờn cu III i tng nghiờn cu IV Phng phỏp nghiờn cu B NI DUNG I C s lý lun Tng quan v Tng tỏc gen - Liờn kt gen - Hoỏn v gen Mi quan h gia Tng tỏc gen - Liờn kt gen - Hoỏn v gen trng hp cp gen nm trờn cp NST quy nh cp tớnh trng 3 C s xỏc nh cỏc loi kiu hỡnh c trng c hỡnh thnh t nhng phộp lai II.Thc trng ca nghiờn cu ti trng THPT III Xõy dng phng phỏp v dung phng phỏp gii bi liờn quan Xõy dng phng phỏp Vn dng phng phỏp gii mt s bi liờn quan IV u im ca sỏng kin 4 23 C KT LUN V KIN NGH I Kt lun 24 24 II Kin ngh A M U I Lí DO CHN TI Chng trỡnh Sinh hc t cỏc cp THCS n cp THPT hin l mt chng trỡnh c xõy dng theo dng "ng tõm xon c" ú m cng lờn cỏc lp hc cao hn, lng kin thc v cỏc nghiờn cu ngy cng sõu v rng hn Chớnh vỡ vy chng trỡnh Sinh hc 12 THPT cui cp ó th hin rừ iu ny vi ni dung ln gm: Di truyn hc, Tin húa v Sinh thỏi hc Vi ni dung cựng vi lng kin thc ln ny ó bao trựm gn ht ni dung ca cỏc thi tt nghip, i hc nhng nm trc hoc thi THPT Quc Gia hai nm hc gn õy nht Trong cu trỳc thi THPT Quc Gia nm 2015 chng "Tớnh quy lut ca hin tng di truyn, phn V Di truyn hc", chim 10 s 50 cõu Tuy nhiờn, thi lng hc chng trỡnh li rt ngn C th nh hc sinh hc chng trỡnh chun ch c nghiờn cu phn ny tit ( cha tớnh tit bi v tit thc hnh ), hc sinh hc chng trỡnh nõng cao cng ch c nghiờn cu tit ( cha tớnh tit bi v tit thc hnh) Trong ú cỏc bi v quy lut di truyn cỏc thi hin thng hi vi nhng cõu hi mang tớnh t cao mc hiu v dng cựng lỳc nhiu quy lut di truyn, vi nhiu d kin khỏc Vi nhng dng bi tng hp nhiu quy lut nh vy i vi hc sinh thc s l khú m vi s lng cõu nhiu mt thi cng nh thi lng hc b mụn li ớt nh vy s khú cú th linh hot dng ht kh nng gii quyt cỏc bi ny Thc t qua nhiu nm ging dy ti trng THPT Hu Lc v ụn thi hc sinh gii, tt nghip, i hc, cao ng hoc gn nht l THPT Quc gia tụi nhn thy rng hc sinh thng bi ri hoc b tc cỏc bi tng hp nhiu quy lut di truyn chi phi phộp lai, khụng ch vỡ nú khú v phc m cũn vỡ thi gian gii kt qu rt lõu, d xy nhm ln Trong ú, xu hng chung ca hỡnh thc kim tra ỏnh giỏ hc sinh hin ang c ỏp dng l s dng cõu hi trc nghim, vi nhng u im nh phm vi kin thc rng, chng c "hc t, hc lch", kim tra c nhiu k nng khỏc ca hc sinh ngoi kin thc Mt khỏc hin ó cú nhiu sỏch giỏo khoa tham kho cng cú cp n cỏc dng bi ny nhng cha nh hỡnh rừ cỏch gii chung hoc nh hỡnh cỏch gii xong cha giỳp hc sinh dng mt cỏch cú hiu qu nht Nhm giỳp HS cú cỏc thao tỏc nhanh gii toỏn tng hp nhiu quy lut di truyn mt phộp lai, tụi mnh dn xut sỏng kin qua kinh nghim thc t ging dy ca bn thõn: " Phng phỏp gii nhanh mt dng bi toỏn tng hp gia quy lut di truyn tng tỏc vi di truyn liờn kt bng cỏch da vo t l cỏc loi kiu hỡnh c trng, chngII, phn V, Sinh hc 12 " Vi sỏng kin kinh nghim ny tụi ch cú mt mong mun giỳp HS thy rừ c mi liờn h mt thit ca cỏc quy lut di truyn m cú cỏch xỏc nh nhanh kt qu lm toỏn trc nghim v bi t lun II MC CH NGHIấN CU - nh hỡnh rừ cỏch gii cỏc dng bi lai cú s t hp ca nhng quy lut di truyn nh + Tng tỏc gen - liờn kt gen + Tng tỏc gen - hoỏn v gen + Vn dng mt s trng hp phõn li c lõp - liờn kt gen, phõn li c lõp hoỏn v gen, phõn li c lp - tng tỏc gen - n gin húa mt s dng bi phc hc sinh cú th gii nhanh hn III I TNG NGHIấN CU Nghiờn cu c s khoa hc mi quan h gia cỏc quy lut di truyn phõn li phõn li c lp - tng tỏc gen - hoỏn v gen, s hỡnh thnh cỏc loi "kiu hỡnh c trng" cỏc phộp lai t ú xõy dng c phng phỏp gii nhanh dng bi lai tng hp ca nhiu quy lut di truyn tng tỏc gen - phõn li - liờn kt gen, tng tỏc gen - phõn li hoỏn v gen IV PHNG PHP NGHIấN CU ti c thc hin da trờn cỏc phng phỏp c bn nh sau: - Phng phỏp nghiờn cu xõy dng c s lý thuyt bng cỏch da vo cỏc ti liu nh SGK Sinh hc 12 C bn, nõng cao, sỏch tham kho v di truyn hc - Phng phỏp thng kờ x lý s liu ( nhiu nm hc, vi nhiu lp hc sinh) thụng qua cỏc bi kim tra, kt qu ca cỏc k thi cú cỏc dng bi liờn ... _41 in the face Our flight was _42 to leave at 10: 30 a.m., and arrived at the airport with plenty of time to spare We started boarding 10: 00 a.m Most of us were holiday makers and there ... important factors for a good teacher-student relationship is the mutual _ A responsibility B respect C support D understanding 43: In order to have a good teacher-student relationship, the teacher... and permissive D ought to strict 44: In order to have a good teacher-student relationship, the student _ A must be a hard-working person B must always support the teacher C must always be a
