Soma makala yafuatayo kisha ujibu maswali:
Usawa wa wanadamu upo kimaumbile – maumbile ya mtu kamwe hayatakosewa na yale ya mnyama wa mwituni. Lakini fikira, tabia, kimo, uwezo na mahitaji huwa tofauti kutoka mtu mmoja hadi mwingine. Kwa mintarafu hii yapasa wakufunzi na wazazi kuwapa watoto wao widhaa mapema ili wachague kwa wakati unaofaa kazi watakayoifanya maishani.
Watoto wanapopelekwa chuoni, wazazi wao huukilia kuwasomesha hadi kiwango fulani cha masomo kisha wajitafutie kazi ambayo itawapa masurufu na pesa za shughuli zingine maishani.
Katika nchi yetu tangu tupate uhuru mtindo wa kutoa kazi umekuwa ni ule wa kuchukua watu waliofaulu mitihani ya viwango fulani na kuwapa kazi moja kwa moja. Mwenendo huu wa kuajiri watu kazi umeendelea muda mrefu lakini sasa yamkinika utasitishwa na njia mpya kufuatwa. Sababu ya kufanya hivyo ni kuwa nafasi za kazi zimekuwa finyu sana. Kabla na punde baada ya uhuru nafasi hizo zilipatikana kila mahali. Nyingi ya hizo ziliachwa wazi na wageni walioihama nchi hii tulipojitawala. Siku hizi wanafunzi wanaokomea darasa la saba, kidato cha pili na hata cha nne huwa hawazioni ahadi za kupata kazi za madaraka fauka ya kazi yoyote. Wanaoiona tabasamu ya kazi mbele yao ni wale wanaotasawari masomoni wakifuata taaluma fulani.
Tatizo la kazi laeleweka vema kwa serikali na ni kwa ajili hii serikali imemtasulia kila mwananchi kuwa wakati wa kuania kazi za utanashati umetimiuka. Wakati uliopo ni wakati wa kujifunga vibwebwe kisaki na kuchapa kazi zile ambazo hadi sasa zafikiriwa kazi chafu na zisizofaa wasomi. Dhana kama hiyo ni ya kibwanyenye, na ubwanyenye hauji ila kwa sulubu. Usemapo kuna kazi nzuri na mbaya huwa unazusha maswali mengi. Utatakiwa ueleze kinaganaga kazi nzuri au mbaya kwa nini? Kazi huwa nzuri kwa upande wa tija au kwa upande wa wepesi wake? Kujibu maswali ya namna hii kutahitaji wekevu mwingi, waima mtesi ataonekana dufu.
Zipo kazi aina mbili. Ipo kazi ya kuajiriwa na ya kujiajiri. Kazi ya kujiajiri kwa kulinganishwa huonekana ngumu na yenye matatizo mengi mwanzoni. Lakini itakubalika pato lake ni kubwa zaidi ikishapata msingi imara. Msingi imara huwekwa kwa juhudi za mwanzoni zikiambatana na ujasiri. Mtu asiyejasiri kutenda tendo lolote maishani ni sawa na yule asiyejua atokako na kule aendako; yuaishi kungozwa. Ardhi ni thawabu, tena thawabu tunu. Ukiwa na kipande cha ardhi ifaayo kwa kilimo ufakiri ukikutawala ni wewe mwenyewe kupenda: la sivyo ufa umo ubongoni unaohitaji bwana mganga

- Usafiri ni upelekezi wa watu na bidhaa au mizigo kutoka mahali pamoja hadi mahali pengine. Tuseme kutoka kituo A na kuenda...(Solved)
Soma taarifa inayofuata kisha ujibu maswali yaliyoulizwa
Usafiri ni upelekezi wa watu na bidhaa au mizigo kutoka mahali pamoja hadi mahali pengine. Tuseme kutoka kituo A na kuenda kituo B.
Katika ulimwengu wa leo, watu na bidhaa husafirishwa barabarani kwa mabasi au motokaa za kila aina au kwa kutumia magari moshi yanayopita juu ya reli, au meli zinazopita majini, kadhalika, usafiri unaweza kufanyiwa hewani.
Hivyo, hali haikuwa hivyo zamani. Usafiri uliojulikana sana kale ni usafiri kwa miguu. Watu waliposafiri kutoka eneo moja hadi jingine walilazimika kufanya hivyo kwa miguu. Kadhalika, watu waliposafirisha mizigo mizito kutoka eneo moja hadi nyingine, iliwabidi kuibeba mizigo hiyo wao wenyewe. Mpaka leo usafiri huu upo.
Wanyama vilevile walitumiwa kama njia moja ya usafirishaji. Huku Afrika ya mashariki kulitumika wanyama wengine kama vile punda. Punda ni mnyama anayependwa sana kwa sababu anaweza kuenda mwendo mrefu pasipo na kunywa maji. Mpaka leo, mnyama huyo hutumika sana na wamaasai, wagala, warendile na wengine.
Mnyama mwingine aliyetumika sana, na mpaka leo anaendelea kutumika ni ngamia. Ngamia anafaa sana katika usafiri wa jangwani. Kwato za ngamia huweza kusafiri kwa urahisi jangwani ama popote penye mchanga mwingi kwa sababu kwato zake hazizami kwenye mchanga. Isitoshe ngamia wanaweza kwenda mwendo mrefu bila maji au chakula huku wakitegemea mafuta yaliyohifadhiwa kwenye nundu zao.
Katika ulimwengu wa kisasa, binadamu amepiga hatua kubwa sana katika masuala ya usafiri. Baadhi ya maendeleo hayo ni ya kustaajabisha. Kwa mfano, binandamu anaweza kuruka kwa kutumia vyombo vya angani kwenda kwenye anga za mbali. Katika karne iliyopita binadamu anaweza kuruka kwa kutumia vyombo vya angani kwenda kwenye anga za mbali. Katika karne iliyopita binadamu amefika mwezini kwa kutumia vyombo hivyo. Kuna tetesi kwamba sasa anajaribu kuzizuru sayari zilizoko mbali na ardhi.
Ama kwa hakika, usafiri bora in kipimo kimojawapo cha maendeleo ya nchi yoyote katika ulimwengu wa sasa. Bila njia ya kisasa za usafiri, baadhi ya mambo yanayofanyika katika nchi zetu hayangefanyika.
(a) Katika habari hii, punda na ngamia wana sifa gani muhimu zinazowawezesha kutumiwa
kwa usafirishaji? (maneno 30-40)
(b) Kwa mujibu wa taarifa, usafiri wa zamani unatofautiana vipi na ule wa siku hizi?

- Nchi nyingi za ulimwengu wa tatu huathirika na biashara ya kimataifa.Biashara hiyo inaweza kuwa inafanya kwa uagizaji ama uuzaji...(Solved)
Soma makala yafuatayo kisha ujibu maswali
Nchi nyingi za ulimwengu wa tatu huathirika na biashara ya kimataifa.Biashara hiyo inaweza kuwa inafanya kwa uagizaji ama uuzaji wa bidhaa za nchi nyingine.
Biashara ya kimataifa ina umuhimu mkubwa. Kwanza, inawezesha nchi kupata bidhaa ambazo haitengenezi mbali na kusaidia kuwepo na uhusiano kati ya nchi mbalimbali. Uhusiano huu huiwezesha nchi kupata bidhaa kwa bei rahisi kuliko ambavyo ingekuwa kama zingetengenezwa kwao, hasa ikiwa nchi inayohusika haina malighafi yanayohusika katika utengenezaji wa bidhaa hizo. Pia husaidia wakati nchi imekumbwa na dharura au majanga kwani itaauniwa na nchi nyingine ingawa hali kama hii haihakikishwi, ushirikiano huu vile vile huchochea upatikanaji wa nafasi za kazi kwa wengi.
Kwa sababu za kushughulikia utengenezaji wa bidhaa na utoaji huduma nyingine kutokana na uzoefu wa muda na kuwepo raslimali, nchi huwa na uzoefu fulani. Ni kwa sababu hii nchi inawezeshwa kupata pesa za kigeni na kuuza bidhaa za ziada.
Hata hivyo kuna matatizo yanayozikumba nchi za kiafrika katika biashara hii. Kwanza, biashara ya aina hii hutatiza viwanda vichanga katika nchi zinazoendelea kwa ushindani usio sawa. Ajabu ni kwamba nchi zilizoendelea zimetumia bishara hii ‘kutupa’ bidhaa za hali ya chini ama zenye athari kwa hali za kijamii.Urafiki haukosi. Ikiwa nchi inategemea uagizaji wa bidhaa, haitaweza kuikosea ama kuhitilifiana na nchi ambayo inategemea, hivyo kuathiri uhuru wa nchi kama hiyo.
Hata hivyo, nchi mbalimbali zimeweka mikakati ya kulinda viwanda kutokana na athari ya biashara kama hii. Baadhi zimeweka ushuru wa juu kwa bidhaa zinazoagizwa utoka nje kwa wasio washirika wa kibiashara. Licha ya hayo, baadhi ya bidhaa zinazonuiwa kwa nje kwa matumizi ya kielimu, utafiti wa kisayansi nabidhaa za maonyesho huagizwa bila ushuru huo. Wakati mwingine ni benki kuu ndiyo hutoa leseni kwa niaba ya serikali kama njia ya kudhibiti bidhaa kutoka nje. Njia nyingine ya kuvisaidia viwanda nchini ni kuuza bidhaa kwa njia ya kuvipunguzia ushuru, usafirishaji nafuu na kuvipa ushuru.
Serikali nyingine huhakikisha kuwa ni bidhaa kiasi fulani tu ambazo zinaweza kuagizwa kwa kipindi fulani. Kwa mfano, kuna idadi fulani ya magari kutoka nje yanayoweza kuagizwa kuja Kenya kwa mwaka mmoja. Hata hivyo, wakati mwingine, serikali husitisha uagizaji wa bidhaa kama vile dawa, sinema, maandishi ya kisiasa na vitabu kutoka nje; bidhaa ambazo zinachukuliwa kuwa hatari kwa nchi. Licha ya matatizo haya, biashara imekuwepo na inaendelea kujiimarisha.

MENO YA BINADAMU
Kila mara tunapokula, meno yetu huuma, kutafuna na kusaga chakula tunachokula. Meno yanatuwezesha kukivunja chakula ili kuwezesha mwili wetu kukitumia. Ili mwili uweze kukitumia chakula hicho, pana vitu fulani vinavyokifanyia chakula hicho kazi mpaka kikaweza kuingia kwenye mwili wenyewe. Hivi hujulikana kama vimeng’enya. Binadamu ana meno ya aina nne kuu. Kwanza, kuna meno ya mbele au makato ambayo kazi yake ni kuuma au kukata chakula. Haya yanasaidiana na mengine yanayojulikana kama michonge; yanakata pia lakini yako sehemu ya nyuma. Michonge hufuatwa na meno mengine yanayosaga chakula na ambayo hujulikana kama masagego. Masagego hufanya kazi na meno mengine yajulikanayo kama magego. Kazi ya aina hizi mbili za meno ni kutafuna na kusaga chakula kabisa kabla ya kukimeza. Idadi ya meno ya mtu mzima ni thelathini na mbili. Bila ya kuwa na meno mazuri, binadamu hukabiliwa na matatizo makubwa wakati wa kula. Meno huweza kuharibika kwa sababu ya kutopigwa mswaki vizuri mara kwa mara. Ili kuhakikisha kuwa meno yetu ni mazuri, pana umuhimu wa kudumisha afya nzuri ya meno. Kila baada ya kulala, lazima tuhakikishe tumeyapiga mswaki vizuri bila ya papara ili kuondoa mabaki ya chakula yanayoweza kuwa chanzo cha viini vinavyoharibu meno. Pili, lazima tuhakikishe kuwa hatuharibu ufizi wa meno,yaani ile nyama inayoshikilia meno hasa kwa vijiti katikati ya meno baada ya kula. Afya ya meno ni muhimu ili kuhakikisha kuwa meno yetu yanadumu na kuendelea kutufaidi katika uhai wetu.

Soma taarifa hii kisha ujibu maswali
Umaskini ni tatizo sugu katika jamii. Binadamu wengi hujikuta katika hali hii kwa sababu hawakubahatika kusoma. Baadhi yao huenda walijaribu kusoma wakashindwa mapema kujipandisha kielimu. Ukosaji wa elimu huchangia sana katika kukuza ukata. Elimu huweza mtu kupata tonge kwa kujipatia kazi za kumwezesha kuyakidhi mahitaji ya maisha. Hali kadhalika, elimu humsaidia binadamu kupata maarifa mengi ya kutendea shughuli zake za kimaendeleo. Kwa mfano, kama ni wakulima wanaweza kutumia pembejeo zifaazo ili kuboresha uzalishaji wa mazao. Wakulima wenye elimu hawatapendelea njia duni za kuendeleza kilimo kama vile kutumia visagilima na mbinu nyingine za kijadi. Badala yake watatumia njia za kisasa za kuvunia mazao yao.
Umaskini mwingine huwa mwiba wa kujichoma. Baadhi ya watu ni mikunguni. Kulaza damu kwao kunawafanya kuwa wategemezi katika familia na jamii kwa jumla. Kwa vile hawajazoea kuinamia cha mvunguni, hata wakifunzwa kuchakura hawawezi. Ili kujaribu kuutibu uwele wao na ufukara baadhi yao hutafuta njia za mkato kama vile upwekuzi wa vitu vya wale waliojitahidi. Wakifanikiwa huweza kufurisha vibindo vyao. Hata hivyo mkono mrefu wa walinda usalama ukiwakumbatia wao hubakia kusagika kwa dhiki isiyomithilika ndani ya magereza.
Majanga ya kimaumbile kama vile mitetemeko ya ardhi, mikurupuko ya maradhi hatari, moto, ukame na mafuriko huchangia na kuzidisha umaskini. Matukio hayo yakiandama kidindia watu wengi huhasirika. Licha ya mali nyingi kupotea, manusura huachwa wakiwa maskini hohehahe. Matumizi yao hupotea kwani wengi huhitajika kuanza maisha upya.
Vijana ni nguzo muhimu katika maendeleo ya nchi yoyote ile. Endapo watajiingiza katika uraibu wa dawa za kulevya, wataathirika wao wenyewe na jamii kwa jumla. Pamoja na kuwa vijana hawa hufuja pesa nyingi katika ununuzi wa dawa hizi, dawa zenyewe huwadhoofisha na kuwapoka nguvu za kushiriki katika uzalishaji mali. Kutokana na hali hii,umaskini hupaliliwa na kushamiri zaidi.
Umaskini huzua matatizo mbalimbali katika jamii. Ufukara huchachawiza juhudi za serikali za kuwapa raia wake mahitaji ya kimsingi kama vile huduma za afya. Pia umaskini husababisha maovu mbalimbali ya kijamii kama vile mauaji na ukahaba.
Baadhi ya wanajamii huona kwamba njia ya kipekee ya kukabiliana na changamoto zinazosababishwa na hali ya ulitima ni kupitia kwa biashara haramu. Hali hii huchochea zaidi kudorora kwa maadili ya kijamii.
Mataifa mbalimbali ulimwenguni yamezua mikakati mahsusi ya kukabiliana na umaskini. Baadhi ya mataifa yamebuni utaratibu maalum wa kupunguza mwanya mkubwa uliopo kati ya matajiri na maskini. Mojawapo ya mipango hiyo ni kupandisha viwango vya kodi inayotozwa wenye mishahara minono na wafanyibiashara wenye pato kubwa. Aidha huduma za burudani hutozwa kodi ya kiwango cha juu. Kupitia kwa kodi hizo, na njia nyinginezo, serikali za nchi hizo hupata pesa za kuwahudumia maskini.
Mataifa yanayoendelea yanaweza kuwakwamua wananchi kiuchumi kwa kuwapa wahitaji mitaji ya kuanzisha miradi mbalimbali ya kimaendeleo. Mifano ya miradi hiyo ni viwanda vya ‘Jua kali’, ususi wa vikapu na uchongaji wa vinyago. Hali kadhalika, serikali inaweza kuwatafutia masoko ya nje wafanyi biashara wadogo wadogo. Aidha, serikali inaweza kupunguza ushuru kwa bidhaa zinazoagizwa na masoko ya nje wafanyibiashara wa aina hiyo. Mathalan, ushuru unaotozwa nguo kuukuu zinazoingizwa nchini ukipunguzwa, wauzaji wa nguo hizi watafaidika zaidi na hali ya umaskini itaendelea kupungua.
Sehemu za mashambani ni mhimili mkubwa wa uchumi. Ingawa kumekuwa na juhudi za kuzistawisha sehemu hizi kwa kusambaza huduma za umeme na maji kwa gharama nafuu, bado hali haijawa ya kuridhirisha. Ili kuimarisha sehemu hizi na kukabiliana vilivyo na tatizo la umaskini, hatuna budi kusambaza huduma hizi hasa katika sehemu kame. Sehemu hizi zikipata maji, kilimo chenye natija kitaendelezwa na umaskini utakuwa karibu kuzikwa katika kaburi la sahau. Ikiwa tutazitekeleza sehemu hizi, vijana wanaoweza kusistawisha watahamia mjini kutafuta maisha ‘bora’. Hali hii itazidisha msongomano wa watu mjini.
Umaskini ni nduli ambaye lazima aangamizwe ima fa ima. Vijana hawana budi kubadili mtazamo wao hasa kuhusu kazi za mashambani na kujitahidi kuimarisha kilimo. Fauka ya hayo, mifumo mwafaka ya elimu ibuniwe ili kukidhi mahitaji ya kiuchumi ya taifa. Badala ya kuhimiza elimu ya kinadharia, elimu tekelezi isisitizwe zaidi ili wale wanaokosa kazi za kiafisi waweze kujiajiri katika kazi za kiufundi. Ukusanyaji wa ushuru uimarishwe zaidi. Hali ya usalama iendelee kustawishwa ili kuzidi kuwavutia wawekezaji, na hivyo kubuni nafasi zaidi za kazi.
