A blog is something like an online journal or diary. In the main page of a blog, there is a set of entries. When the author adds a new entry, it goes at the top, pushing all the older entries down. A blog might also have a sidebar that contains additional links to other websites. The author of a blog can write about anything and everything on his mind. Blogs often contain stories or little snippets of information that have caught the attention of the author. Even though blogs can be completely free-form, many blogs have a focus. For example, if a blogger is interested in technology, the blogger would post entries on the latest technological gadgets. Some people use their blogs simply as a scrapbook or a form of online memory the blog is useful to the author because the blog is searchable electronic medium that the author can access with a Web browser from anywhere in the world, at anytime of the day.

The cutting and burning of tropical forests worldwide emits at least 20 percent of total global greenhouse gases. Protecting these forests minimizes the impact of climate change while providing direct benefits to local populations, such as fresh water, clean air, food, seed dispersal, pollination and sources of medicines.

All the known elements differ from each other in the number of protons their atoms contain. An atom with a single proton, is a hydrogen atom, and is given the atomic number 1. An atom with two protons is a helium atom, and has the atomic number 2 and so on. Uranium, the largest of naturally occurring elements, has an atomic number 92. Fortunately, no one has to memorize the atomic numbers of all the elements, because a periodic table is provided in most chemistry texts. The periodic table lists all of the known elements in the order of their atomic numbers.

Question 7 - 8

7. Why should phones be recycled?I To avoid the leaching of toxic substances into the environmentII To avoid the release of toxic substances that could affect healthIII To recover and reuse useful materials such as precious metals

A I and IIB I and IIIC II and IIID I, II and III

8. What precious metals can be found in phones? A Nickel and gold B Cadmium and silver C Gold and silver D Nickel and cadmium

Questions 9 – 10


4

Although phones seem to be made from harmless plastic, they have many nasty chemicals hidden inside them. Their plastic covers contain flame retardant additives that can give rise to toxic dioxins if incinerated, the cadmium in nickel-cadmium batteries is known o be toxic and carcinogenic and there are other toxic metals in the circuit board. When consigned to a landfill, phones could remain there for hundreds of years, leaching their toxic chemicals into the soil and potentially into water supplies. Recycling phones means that toxic substances can be removed and precious metals such as gold and silver can be recovered and used again in other products.

The purpose of the roller coaster’s initial ascent is to build up a reservoir of potential energy. The concept of potential energy, often referred to as energy of position, is very simple: As the coaster gets higher in the air, gravity can pull it down a greater distance. The potential energy you build going up the hill can be released as kinetic energy – the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.

A diamond is the hardest natural substance on earth. It has a value of 10 on the Mohrs scale compared to glass which has a value of 6 or talc with a value of 1. But if a diamond is placed in a oven and the temperature is raised to about 763 degrees Celsius, it will, simply vanish, without even ash remaining. Only a little carbon dioxide will have been released.

Climatologist are people who study the climate, the weather that a region (26) _________ over a long period of time. The basis of climatology is an understanding of the differences in seasonal weather from one region of the world to the next.

These days, the focus of climatology (27) _________ on climate change. One way scientists predict climate change is by discerning a shift in weather patterns. Regions undergoing desertification, for example, sometimes experience a rise in average temperatures and a decrease in precipitation. Climatologist also look for changes in the global (28) _________ .

To find answers, climatologist look at phenomena such as volcanic clouds, fluctuations in the Sun’s intensity, and human activities that might (29) _________ the weather. Many climatologist work closely with biologists and oceanographers to understand how the atmosphere is influenced by things such as plant cover, livestock grazing, and ocean currents.

Climatologists also look into the past to compare the present day atmosphere to that of the past. In the Antarctic for example, climatologists study the air trapped in samples of ancient glacial ice. They have discovered that the amount of methane in the lower atmosphere is nearly 2.5 times higher today that at any time in the past 160, 000 years. Methane is a gas that may contribute to global warming. Climatologist have (30) _________ that a surprising source has been contributing to the volumes of methane – cattle which produce and expel methane as part of their digestive process.

Four main forces act on the aircraft when it is in the air. The aircraft’s weight continually pulls it down towards the ground. The wings provide the lift which counteracts the weight and helps the aircraft to stay aloft. The air around the plane rubs against it to provide the drag to hold the aircraft back. The aircraft’s engine provides the thrust to drive the plane forward to counteract the drag. The aircraft can move forward when the right balance is kept between the four forces.
