         Chagas disease, also known as American trypanosomiasis, is a potentially life-threatening illness caused by the protozoan parasite Trypanosoma cruzi. About 6-7 million people worldwide are estimated to be infected with T. cruzi. The disease is found mainly in endemic areas of 21 continental Latin American countries, where it has been mostly transmitted to humans and other mammals by contact with feces or urine of triatomine bugs (vector-borne), known as kissing bugs, among many other popular names, depending on the geographical area.

        Chagas disease is named after Carlos Ribeiro Justiniano Chagas, a Brazilian physician and researcher who discovered the disease in 1909. Chagas disease was once entirely confined to continental rural areas of the Region of the Americas (excluding the Caribbean islands). Due to increased population mobility over previous decades, most infected people now live in urban settings and the infection has been increasingly detected in the United States of America, Canada, and many European and some African, Eastern Mediterranean and Western Pacific countries.

           Chagas disease’s transmission is caused by T. cruzi parasites, which are mainly transmitted by contact with feces/urine of infected blood-sucking triatomine bugs. Normally they hide during the day and become active at night when they feed on animal blood, including human blood. They usually bite an exposed area of skin such as the face (hence its common name, kissing bug), and the bug defecates or urinates close to the bite. The parasites enter the body when the person instinctively smears the bug’s feces or urine into the bite, other skin breaks, the eyes, or the mouth. T. cruzi can also be transmitted by consumption of food or beverages contaminated with T. cruzi through, for example, contact with feces or urine of infected triatomine bugs or common opossums. This kind of transmission typically causes outbreaks with more severe cases and mortality; passage from an infected mother to her newborn during pregnancy or childbirth; blood or blood product transfusion from infected donors; some organ transplants using organs from infected donors; and laboratory accidents.

        Many assumptions of a communicative orientation towards language teaching need questioning in a global context. Ozóg (1989) discusses the idea of the ‘information gap’, which is supposed to induce students to speak. ‘Are we as Europeans’, he asks, ‘not making a cultural assumption that speakers the world over are uneasy in silence and that they have an overwhelming desire to fill gaps which occur in natural discourse?’ (p.399). Silence is a salient feature of conversation in the Malay world, he points out, a feature that has also been noted in Japan and a number of other cultures.

       Indeed, the whole question of requiring others to speak needs to be questioned in terms of both cultural and gender differences. The point here is not to exoticize some notion of cultural difference, but rather to suggest that language is a cultural practice, that both language and thinking about language are always located in very particular social, cultural and political contexts. How language (including silence, paralanguage, and so on) is used, therefore, differs extensively from one context to another, and thus any approach to language teaching based on one particular view of language may be completely inapplicable in another context. If particular language teaching practices (advertised and exported as the best, newest and most scientific) support certain views of language, then such practices clearly present a particular cultural politics and make the English language classroom a site of struggle over different ways of thinking about and dealing with language.

    A French astronaut has used a video call from space to sound the alarm about worsening repercussions from climate change that he can see ______ the International Space Station.

       Entire regions of Earth in flames. Storms trailing destruction in their wake. And the haunting fragility of humanity’s only home floating like a blue — but also tarnished — pearl in the vastness of space.

      Through the portholes ______ the International Space Station, French astronaut Thomas Pesquet has an arresting view of global warming’s repercussions. He used a video call from space to sound the alarm Thursday, as negotiators, government officials and activists continued meeting at a U.N. climate conference in Glasgow, Scotland.

        “We see the pollution of rivers, atmospheric pollution, things like that.”

        “We saw entire regions burning from the space station, ______ Canada, in California,” he said. “We saw all of California covered ______ a cloud of smoke and flames with the naked eye from 400 kilometers (250 miles) up.”
