    This research paper focuses on increasing the awareness between taxi users and can help to protect themselves in COVID-19 and take precautions. Since 2019 the global pandemic of Covid-19 is spreading at an astonishing rate and causes a negative impact for economic, social, and cultural factors. Government agencies are warning people to reduce the transportation and to maintain social distance. To stop the spread of COVID-19 required to identify persons who are susceptible to infection and need to trace the COVID-19 positive first contacts. Most people are reduced to using public transportations and taxi services due to unidentifiable health conditions in earlier users. The proposed approach can be used to track the taxi drivers and their passengers previous COVID-19 status as well as navigate the safest route by showing the COVID-19 contamination areas. By using this approach users can be aware of earlier users of the taxi service and COVID-19 status of the taxi driver or passenger before taking the trip as well as if they get touch with any COVID-19 patients, can take immediate precautions. This application helps to increase the usage of taxis by making users trust and confidence against COVID-19 infection. By testing with real users our system was able to trace down 45 passengers and 16 drivers within 3 months.

    Information, processed from Knowledge, occupies center stage in this era and literacy in English is vital to deal with this information towards challenges of this digital age. A sound knowledge of English proves essential for success or prosperity not only to the dasiatechno-richpsila but also to nations struggling to meet demands of globalised economies requiring accessing and filtering such information. Information Communication Technologies (ICT) has surfaced as a benefactor towards acquisition of language skills in English to tackle challenges in education. Using ICT, it is found that adaptive and blended learning in English could contribute much towards proficiency in English, illuminating the lead to the information highway towards advancement in the knowledge economy. Where adaptive learning allows for a continuation of learning from a position, blended learning combines traditional classroom teaching with learning online or through a computer screen. Taken together, adaptive, blended learning encourages progress from a stagnant position through new technologies developed for a self-access approach. Blended learning, combining online learning and traditional approaches helps with self-learning processes. Overall, blended learning allows for mass customization with Web 2.0 and social networking, currently in vogue. Learning materials or dasialearning objectspsila used for social networking with Web 2.0, lend much support to online learning in English towards self or peer learning, working collaboratively in small groups or participating in interactive classroom sessions. This paper highlights attempts towards improving language proficiency in English of tertiary level students on the threshold of graduate courses, using a blended, adaptive learning process with Web 2.0.
