BIOLOGY
The word biology/comes from two Greek words/: bios, meaning life, and logos,
meaning a word or a discourse, /so/ biology is the study of life. /But what is life?/ What is
really meant by saying/ that one object is living /and another is nonliving?
Biologists, a person who is expert in biology,/ call living things organisms./ The
word organism means/ an individual living thing;/ whether it is a plant,/ an animal or/ a
microbe. /To try and see what is meant by ‘life’ and ‘living’,/ we will do what a biologist
normally does /as part of his or her research./ First, ask question. /What are living things
like? /What do they do? /In what ways/ are the things we call ‘living’ different from/ those
we call ‘nonliving’? /Secondly, collect evidence that might help/ answer those questions./
Evidence usually comes /by direct observation and measurement of living things, /and by
reading what others have found. /Thirdly, use the information obtained -the data- /to try
and answer the questions. /Some data collected by biologists in recent years/ can help you
answer these questions. /The first set of data concerns a fairly typical animal;/ the second
concerns some fairly typical plants.

A. Skimming
Skimming is a technique used to look for the “gist” of what the author is saying without a
lot of detail. It is used I you just want a review or an overview of the material. Skimming is also
used after a person has already carefully studied and he needs to review the major ideas and
concept.In preview skimming, you must read the introductory information, the headings, and
sub-headings, and the summary. Then, decide to read the material more thoroughly and rapidly.
Another procedure of skimming would be only read the key words. The key words could
be (1) the topic (place, people, dates), (2) the descriptive adjectives (negative, positive, effective,
impressive), (3) the abstract nouns (concept, power, love), and (4) the function words (and, but,
for, to). To skim by reading the key words means skip some unnecessary words, phrases, and
sentences and still continue reading. Skimming is a skill that requires concentration, adequate
knowledge of vocabulary, and comprehension skill. The example of skimming task: “How many
kingdoms are used to classify living?”
B.Scanning
Scanning is a technique used to locate specific information by scanning to find the
information you need. You do not need to read carefully. Scanning is a searching that requires a
reader over the material until you find what you need. Then you stop and read as much as
necessary in order to answer your questions.
To scan effectively, you should have a clear idea of what you are looking for, where you
are likely to find it, and how he can recognize the information when you see it. Looking for a
name, for instance, capital letter will be the clue. The example of scanning task: “What program
would be appeal to teenagers.”

Specific comprehension skills cannot be completely isolated because they are so
interrelated that one skill depends to some degree on another skill. Comprehension can be
divided into three levels of skills: literal, inferential, and critical.
1. Literal reading refers to the ideas and facts that directly stated on the printed page.
Literal ideas and facts are usually so clearly that you can go back in the passage and
underline the information needed.
2. Inferential reading is to get inferences or implied meanings from the reading materials.
You should read between lines. Inferences are ideas you receive when you go beneath the
surface to sense relationships, put facts and ideas together to draw conclusions and make
generalizations, and detect the mood of the materials.
3. Critical reading requires a higher degree of skill development and perception. Critical
reading requires reading with an inquiring mind and with active, creative looking for
false statements by questioning, comparing, and evaluating.
One of the most important comprehension skills is finding the main ideas. The main idea is often
found in the first sentence in a paragraph followed by supporting details. Yet, some authors
prefer to give the supporting details first and end with the main idea. Sometimes, others give the
supporting details, the main idea, and then more details. For that reasons, you should have a plan
to find the main idea. These three questions can help you.
1. What is the subject of the paragraph?
2. What is the purpose of discussing the subject? (to inform, explain, define, etc)
3. What idea is the author trying to make the you/reader understands about the subject?

trees, and classified animals on the basis of size, where they lived—on the land or in the water,
and how they moved. Although Aristotle’s system of classification did little to reveal natural
relationships among living things, it was widely accepted and used, with few modifications, into
the Middle Ages.

THE SIXTH KINGDOM
In the 1970s, genetic tests showed that members of the kingdom Monera were far more diverse
than anyone had suspected. One group of bacteria, originally called archaebacteria (ancient
bacteria), seemed especially unusual. Archaebacteria, or archaeans, as most biologists now refer
to them, often live in extreme environments— very hot or salty places— such as the Grand
Prismatic Spring in Yellowstone National Park. In 1996, researchers sequenced the archaean
genome and discovered that these tiny cells are as different from bacteria as you are. A sixth
kingdom was formed.
