Passage 1

Light is made up of electromagnetic waves. These vary in length and it is these differences that we perceive as different colours. White light has all the wavelengths of the light spectrum mixed up together. An object looks coloured because light falls on it and it reflects only certain parts of the spectrum. The rest of the spectrum is absorbed by the object. An object that looks white reflects all the light that falls on it. An object that looks red reflects the red part of the spectrum and absorbs the rest. Our eyes detect these different reflected waves and we see them as different colours.

Passage 2

Traditionally medicine was the science of curing illness with treatments. For thousands of years people would have used plants and would have turned to priests for cures. In more recent times illness has been attributed less to the intervention of gods or magic and instead to natural causes. Medicine today is as much concerned with prevention as cure. Doctors use treatments of many types, including radiation and vaccination, both of which were unknown until very recent times. Other treatments have been known about and practiced for centuries. Muslim doctors were skilled surgeons and treated pain with opium. When Europeans first reach the Americas they found healers who used many plants to cure illnesses. The Europeans adopted many of these treatments and some are still effective and in use today.

Passage 3

In tropical rainforests the climate remains hot and damp all the year round. In the artic it is cold all year and high up in mountain ranges the climate is much colder than in nearby low lying lands. Climate is not the same as weather. The weather can change quickly whereas the climate describes the likely weather conditions over a much longer period of time. The world is divided into five climate zones. Polar is the only zone where it is always cold, tropical where it is hot all year round, temperate where there are warm summers and cold winters, desert where it is dry and cool, and forest where the summers are cool and short. Great climate changes have occurred, an example of which is the last ice age. Mankind can affect climate when, for example, he causes great forest fi res that create so much smoke that the sun is obscured for months, cooling a region. More recently man has affected the climate as a result of pollution from industry causing the earth to warm through what is called the greenhouse effect.
