    Writing exercise Hi there, on my way to improve my English and prepare myself for some test required to apply to many colleges abroad I made this essay about an interesting article that I read recently. I hope that someone can provide me with some comments about this article that help me to improve. The ocean, the biggest sicker in the world The researchers around the world are concerned about the health of the oceans. They are sick and getting sicker every day. There are three main problems that our oceans have to face: the reduction of oxygen levels, the increase in atmospheric temperature and the pollution. First of all, the increase in the temperature is breaking the balance in the oceans. Warm water is not capable to hold as much oxygen as cold water does. In addition, the changes in the winds and water-currents caused by the temperature make difficult the mix water and the air. In consequence, the reduction in oxygen levels is worse than the scientists believed. Since 1950, the low oxygen zone in the ocean has grown about 60%. Nowadays, this zone is greater than the Africa continent. As a result, the coral bleaching (the loss of color and die) has been increasing. Before to 1980, this event happened every 25 to 30 years, but now the researchers report a harsh coral bleaching every 6 years. Whether the coral reef dies all of the species associated to it will die too. A study performed in 100 coral reefs showed that only 6 don’t present signals of coral bleaching. Besides of that, the pollution is another important problem that our oceans have to face. The presence of many different compounds is threatening the marine life. The plastic pollution is one of the worse. A single piece of plastic takes about 800 years in breaking down. As a consequence, the researchers have estimated, by 2050 the concentration of plastic in the oceans will be greater than the fish. Take care our ocean is so important because they support the life and help to maintain the balance in the world. If the human can’t solve or ease these problems, they will provoke an inhabitable catastrophe.

It has the challenge the solve the nowadays problem and fixes the problems that humans have been accumulating throughout their history. In that sense, the solar energy project in Mekong River and in many other of tributary river show themselves how a great improvement. Cambodia has been able to organize and improve its solar plants in actually few time, reaching nowadays a production of 6000 mW. It represents an important source of energy and important improvement with respect electric energy produces by hydropower dams. Furthermore, the use of solar energy looks a great economic and eco-friendly alternative. In the last four years, the costs linked with the solar energy has fallen making the solar energy more accessible. Other important problem in the Area, it’s the use of the territory. The government and experts endorse the idea that solar Energy equipment could be placing on the water in Reservoir Park. Therefore, the use of the land will reduce, a great improvement in contrast to hydropower dams. The world is changing faster, Asia has been the fastest continent to implement the solar technology. For instance, China plans to put in operation a big solar plant by 2020. In that sense, the solar energy technology has begun to be a global trending.

    Hello Wanda, you are right. “Enseñarme” can be use in the context of teach something or show something to someone. Estas en lo correcto, puede usar “enseñarme” en el contexto de enseñar un tema o mostrar algo. Examples Teach context - ¿Podrías enseñarme a cocinar? - Wanda me enseñó a cocinar - Camilo me está enseñando cocina Show context -¿qué tienes oculto? Enséñame

    Hello Susan, We can sorted the leaves of the plants in two groups. In simple and compound leaf. If the leaf of a plant is separated into distinct leaflets (foliolos) is called compound leaf. But, if the leaf is not divided is called simple leaf Foliolada means in a simple way: compound leaf Foliolo: One of the parts of a compound leaf Look this link: http://www.acguanacaste.ac.cr/paginas_especie/magnoliophyta/fabaceae/mucuna_pruriens/m_pruriens_5mayo1999/mucuna_pruriens_high/ACG-PI-d-5730_g.jpg This is one leaf of the common bean. This is a compound leaf with three leaflets (es una hoja compuesta o foliolada con tres foliolos) How you can know if one leaf is simple or compound? Look the following picture. https://www.amnh.org/var/ezflow_site/storage/images/leaf_type-5-6/568274-1-eng-US/leaf_type-5-6.gif Each leaf has an axillary bud (In Spanish is: “Yema”). The axillary bud is the point where the leaf begins. If you see one or simple leaf after of axillary bud is a simple leaf. However, if you can count different parts this is a compound leaf. In this picture, the leaflet are opposites that means that the leaflets are one in front of the other. In the opposite case when the leaves or leaflets are not in front each other is called alternate leaves or leaflets. The terms opposite and alternate is use to describe leaves and leaflets. (hojas o foliolos opuestos / hojas o foliolos alternos) I am learning English I hope that the explanation was clear.

I would like to receive advices and corrections about my written. Scientists had been studying a way to use common bacteria to control the population of mosquitos that carrying-diseases such as Sika Virus and Dengue. In this sense, it could be possible to stop these diseases when stopping the organisms that transmit it. The bacteria of the genera Wolbachia can infect up 70% of insect on earth, including the mosquito called: Aedes aegypti. This mosquito transmit the Sika virus and Dengue. Sika virus could be dangerous in special in woman early in her pregnancy. due to sika virus may cause microcephaly in the babies, this cause mental and physical disabilities and in sometimes could be deadly. On the other hand, people infected with dengue develop similar condition like influenza, but the symptoms are more strong and also turn deadly. Wolbachia act as parasite in the mosquitos affecting the capacity of reproduction. Researchers indicated that is possible to control the mosquito population by means of liberation of infected mosquitos with Wolbachia to environment.
