1. because it stands neglected as it degrades and leaks into the earth without any control at all. Changes in the water chemistry due to surface water contamination can affect all levels of an ecosystem. It can affect the health of lower food chain organisms and, consequently, the availability of food up through the food chain. It can damage the health of wetlands and damage their ability to support healthy ecosystems, control flooding, and filter pollutants from storm water runoff. The health of animals and humans are affected when they drink or bathe in contaminated water. In addition water-based organisms, like fish and shellfish, can pile up and concentrate contaminants in their bodies. When other animals or humans eat these organisms, they receive a much higher dose of contaminant than they would have if they had been directly exposed to the original contamination. Contaminated groundwater can badly affect animals, plants and humans if it is removed from the ground by manmade or natural processes. Depending on the study of rocks of the area, groundwater may rise to the surface through springs or seeps, flow sideways into nearby rivers, streams, or ponds, or sink deeper into the earth. In many parts of fhe world, groundwater is pumped out of the ground to be used for drinking, bathing, other household uses, agriculture, and industry. Contaminants in the soil can harm plants when they take up the contamination through their roots. Eating, breathing in, or touching contaminated soil, as well as eating plants or animals that have piled up soil contaminants can badly affect the health of humans and animals. Air pollution can cause breathing-related problems and other bad health effects as contaminants are absorbed from the lungs into other parts of the body. Certain air contaminants can also harm animals and humans when they contact the skin. Plants rely on breathing for their growth and can also be affected by exposure to contaminants moved in the air.

3. APPENDIX 2 Post- test Name: Class: .Marks: Read the following passage and write the letter A, B, C or D on the top of the first page to indicate the correct answer to each of the questions. The incredible growth of the Internet over recent years has caused problems for parents and teachers. Parents worry about which sites their children spend time on, who they chat to online and the possible effects that computer games might have on them. For teachers, meanwhile, the main worry is the way the Internet makes cheating easier! Schools and universities say there has been a huge increase in plagiarism – taking other people‟s words and ideas and pretending that they are your own. In the past, anyone who wanted to copy had to go to a library, find the right books, read through them, find the sections they needed and then physically write down the words they wanted to use. Nowadays, though, students can simply copy extracts from websites-while really desperate students sometimes copy whole essays! As if this wasn‟t bad enough, sites offering to actually do homework – at a price – have also started appearing. Despite all this, we shouldn‟t assume that the Internet only brings problems. Indeed, you could say that for every problem the Internet creates, it also brings a solution. Parents can now use sophisticated controls to stop kids accessing sites that might do them harm, while new software helps teachers to detect copied work immediately. Many, of course, are already able to recognize when someone is cheating! „Some students suddenly start using words they can‟t possibly understand like „dialectical antagonism‟,‟ explains one teacher, „or parts of their essays feel different.” One of the hardest things for teachers today is deciding how to mix modern technology with traditional study skills – and how best to use the Web in class. As more and more schools install computers in every classroom, the role of the teacher is changing. Making sure students don‟t just copy things and do learn how to quote copied work properly is part of their job, but so is designing suitable projects to fully exploit the Web in helping students students learn about subjects and develop their life and social skills.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions Unlike these fish, which are actually extinct, the coelacanth is a type of fish that was believed to be extinct. However, an unexpected twentieth- century rediscovery of living coelacanths has brought about a reassessment of the status of 46
5. the prehistoric sea creature that was believed to have long since disappeared from the Earth. From fossil remains of the coelacanth, paleontologists have determined that the coelacanth was in existence around 350 million years ago, during the Paleozoic Era, more than 100 million years before the first dinosaurs arrived on the Earth. The most recent fossilized coelacanths date from around 70 million years ago, near the end of the age of dinosaurs. Because no fossilized remnants of coelacanth was believed to have died out around the same time as the dinosaurs. The prehistoric coelacanth studied by paleontologists had distinctive characteristics that differentiated it from other fish. It was named for its hollow spine and was known to have been a powerful carnivore because of its many sharp teeth and a special joint in the skull that allowed the ferocious teeth to move in coordination with the lower jaw. It also had a pair of fins with unusual bony and muscular development that allowed the coelacanth to dart around the ocean floor. These fins also enable the coelacanth to search out prey trying to hide on the ocean bottom. In 1938, a living specimen of the coelacanth was discovered in the catch of a fishing boat off the coast of South Africa, and since then numerous other examples of the coelacanth have been found in the waters of the Indian Ocean. This modern version of the coelacanth is not exactly the same as its prehistoric cousin. Today's coelacanth is larger than its prehistoric relative, measuring up to six feet in length and weighing up to 150 pounds. However, the modern version of the coelacanth still possesses the characteristic hollow spine and distinctive fins with their unusual bony and muscular structure.
