Main Idea
1. Despite the hatred that most people feel toward cockroaches, they do help humans in several ways. For example, they are perfect experimental animals and are used for scientific research in the laboratory. Breeding them is easy, for they thrive under almost any condition. In studies on nutrition and food, cockroaches are good subjects because they will eat any kind of food. They can be used to study heart disease, and cancer researchers work with roaches because they grow cancerous tumors like those that are found in humans.
Which sentence in the paragraph contains the main idea?
a) in the first sentence
b) in the second sentence
c) in the third sentence
d) in the fourth sentence
e) in the last sentence
2. Making a study schedule is one important step in becoming a successful student in college. Students should schedule one hour of study time for every one hour of class time. At exam time, more study time may be necessary. Also, students must study in an appropriate place. It is important to study in a quiet place away from the distraction of other people and such things as the television and the radio. Students should find a comfortable place with plenty of space for all the necessary study supplies. Then, students need to study the information in small amounts. It is a good idea to learn the required concepts slowly and thoroughly instead of trying to learn everything on the evening before the exam. Students who want to be successful in college should remember these three helpful study strategies.

Read the flowing paragraph
In 1588, the Spanish Armada sailed to fight against England. The Armada consisted of a fleet of 130 ships. Aboard one of these ships was a tailless cat. Her job was to catch mice. After a great naval battle that England dominated, the Spanish ships set sail for home. The cat’s ship was wrecked near the Isle of Man. The nimble cat got ashore safely and lived there ever after. Her many descendants become known as Manx cats after the name of their island home. Manx cats are known for being tailless.

Point of View
The Presidential Campaign
[pic]I am an American. Perhaps that makes me a little biased, but I believe that the American presidency is the most important job in the world. It’s a job that goes up for grabs every four years. The candidate who wins in November of 2000 will take office the following January and be the first new U.S. president of the twenty- first century.
[pic]The election campaign is a long one. Some say it begins right after the election and goes on for the next four years. That’s probably an exaggeration, but it does last a long time. Those who have their eyes on the job have to start gathering support and building campaign organizations early.
[pic]Some believe that the campaign for president should be shorter. I disagree. A long campaign is an endurance contest. It gives the candidates a chance to show their strengths and forces them to betray their weaknesses. The extended scrutiny makes it much less likely that the voters will accidentally choose an unqualified candidate to be their leader.
[pic]Personally, I enjoy the contest. It’s a marathon that produces a winner who may have a profound effect on all our lives. You can have your playoffs and your championships; the debates, primaries, conventions, and November election are the sporting events that really matter!
Read the following statements. Based on the author’s essay, decide what his opinion would probably be. Write “agree” after the statement if he would most likely agree with the statement. Write “disagree” if he would most likely disagree.
1. America has lost its importance in the world. ___D______
2. The U.S. presidential election should be limited to six months. ___D_______
3. Political debates are always boring. _____D______
4. Longer campaigns produce more qualified winners. _____A______
5. Politics is more important than sports. ____A_______
6. Sometimes it takes time to realize that an attractive candidate would be a poor choice. ____A_______
7. The president of the United States must be able to handle a difficult and important job. _____A______
8. Politics can be entertaining. _____A______

This means that the information is never clearly stated.
*On any reading test, you'll probably see questions that ask you to infer, make an inference, or draw a conclusion. These all mean the same thing.
*You have to find clues in the passage and use your own background knowledge in order to answer the question.
Read the following paragraph.
Prairie dogs are not really dogs; they’re rodents. However, like canines, prairie dogs communicate by barking. Many of the sounds they make alert their colony of danger. For example, prairie dogs have one call for coyotes and another for hawks. When a coyote is sighted, other prairie dogs pop up from their burrows to keep track of where it goes. If a hawk is seen, they dive into their burrows. Prairie dogs make other sounds when humans are near. Most surprisingly, prairie dogs have distinct calls for different kinds of real dogs.
Place an X in the matching box
|Fact |Inference | |
| X | |Prairie dogs are actually rodents |
| |X |Hawks are bigger threats than coyotes |
| X | |Prairie dogs make barking sounds |
| X | |Prairie dogs have special calls for people. |

|Read this passage about transportation in New York. Complete the chart comparing trade and towns in New York before the canal was built to trade |
|and towns after the canal was built. |
| |
| Transportation in New York improved during the 1800s. The Erie Canal was one improvement in transportation. Work on the Erie Canal began in |
|1817. The canal was completed 8 years later. 13,000 boats traveled on the canal in the first year. The canal was a big success. While the trip |
|between Buffalo and New York took 20 days before the canal was finished, that same trip took only 8 days on the canal. |
| Goods shipped over land cost $100 a ton before the canal was built. The same amount of goods could be shipped on the canal for only $10. |
|This led to increased trade along the route of the canal. Lumber and wheat could be shipped east and, in turn, products from the east could be |
|shipped to settlers in the western part of New York. |
| The increase in trade led to the growth of cities along the canal route. In 1825 when the canal opened, Buffalo had a population of about |
|2,400 people. That population grew to 10,000 in just 6 years. Rochester had a population of only 331 in 1815, but by 1827 the population had |
|grown to 8,000. |
| |
|Compare and contrast New York before the canal to New York after the canal was built.. |
|How alike? |How different? |
| Trade with New York and Buffalo |Transportation improved |
| | |
| | Buffalo to NY- only 8 days now |
| | Increases trade along the canal |

Another Peter Pan
by Claudette J. Young
Floating around our oceans is a small menace that can return itself to its infancy.Turritopsis nutricula (Turri-top-sis nu-trick-u-la) isa hydrozoan jellyfish and the only known jellyfish that can deliberately go back to its polyp stage repeatedly. This ability also makes it a potential menace worldwide.
Turritopsis nutricula begins life as a polyp
(a tiny seed of life) that attaches itself to a piece of coral or rock. It grows there until it reaches maturity when it grows delicate but deadly tentacles.
These clear-bodied examples of floating poison are the only known immortal animal on the planet. During adulthood an unknown event triggers a regeneration response in the jellyfish. Unlike other animals, like salamanders that regenerate a specific part of their bodies,Turritopsis nutricula returns itself to its polyp stage of development, reattaches to a piece of coral, etc. and starts life again. Generations of their offspring remain to grow, too. Unless killed by a predator, they keep living their lives over and over. Experts believe this repeat performance can happen indefinitely.
Researchers know that the mechanism for the rejuvenation process is genetic, but the ultimate trigger for that process still stumps the experts. The increasing numbers of the jellyfish species alarm the world’s fishing industry. Researchers and environmentalists are as alarmed as fisherman.
These jellies have few predators, which have dwindling numbers. The neuro-toxin carried in their tentacles works on most fish. These ordinary Caribbean jellyfish now live in ocean waters from the Arctic to the Southern Ocean and also tolerate fresh water.
Experts and fisherman fear that the world’s oceans might become this jelly’s Never Never Land. A population explosion could reduce the ocean’s fish population to dangerously low numbers. Only time and research will provide the end to this tale.

Immune Troops! Move In!
by Shauna Hutton
Your body has a very special system that protects you from illness and disease. It’s called the immune system and it knows when there is something inside your body that should not be there.
All the cells in your body have a way to tell the immune system, “I belong here. I’m not going to do any harm.” And so the immune system leaves those cells alone. Think about the cells in your body wearing name tags that say “self”. Anything with a “self” name tag is a good guy. But things like bacteria, viruses, and parasites wear name tags that say “nonself”. When the immune system sees a “nonself” name tag, it jumps into action and attacks those foreign invaders. Any foreign substance in your body that makes the immune system attack it, is called an antigen. These antigen invaders can be pollen from the air, a virus, or certain types of bacteria.
There are many different kinds of immune cells helping to keep you from getting sick. They can be grouped into phagocytes (pronounced fag-uh-sahyt) and lymphocytes (pronounced lim-fuh-sahyt).
Phagocytes are a type of white blood cell, and one of their jobs is to gobble up and digest antigens. They are always swimming around in your blood stream, always on the lookout for antigens. And when they see one, GULP!
Lymphocytes are also white blood cells and the main types are B cells, T helper cells, and T killer cells. Many antigens can be very sneaky (like viruses) and can hide from phagocytes, so it’s the job of the lymphocytes to find them and get rid of them. Viruses will kill healthy cells in the body. White blood cells, like the one pictured above, attack the harmful bacteria, viruses, and parasites that enter your body.
B cells secrete (produce) substances, called antibodies, which stick to the antigen. When that happens, it alerts the T helper cells to come over and either:
1. help the B cells destroy the antigen, or
2. call the phagocytes or T killer cells to move in for the kill
T killer cells are really good at finding and killing cells that have been infected by a virus.
Once a B cell or T cell attacks an antigen, they create cells to “remember” it. Those “memory cells” hang out in your blood and if they see that same antigen again, they quickly recognize it so your immune system can act faster at killing it.
The “B” in B cells stands for bone marrow, which is where B cells, and all immune cells originate from. The “T” in T cells stands for thymus. Young T cells start out in bone marrow, but they travel to the thymus to continue growing into mature T cells. The thymus is an immune organ located in the middle of your chest, near your heart. Its job is to produce mature T cells.
You have your own little army of cells inside you, always fighting to keep you healthy. And you can be a part of that army too! By getting plenty of sleep at night and eating nutritious foods, you’ll help keep your immune system strong and ready to fight. Go immune troops! Go!
1. What does your immune system do?
a. makes you sick
b. keep your brain sharp
c. protect you from illness
d. make energy for your body
2. Define the word antigen. Give 3 examples of antigens.
__antigen- any foreign substance that the immune system attacks Pollen

Master of the Grasses
by Guy Belleranti
What would you do if you saw a guinea pig that weighed 75, 100 or even 150 pounds? Of course, guinea pigs don’t grow nearly that big, but if you saw a capybara, you might mistakenly think it was a giant guinea pig.
The capybara, which lives in South and Central America, is the world's largest species of rodent. It has a barrel-shaped body, a short head with small ears, and it can grow to be over four feet long.
The name "capybara" means "master of the grasses". You see, capybaras are vegetation eaters, and grasses are the main food in their diets. Capybaras have two pairs of large incisor teeth to bite off grasses, tree bark, and other vegetation. Most animals have teeth that stop growing, but rodents like the capybara have a different kind of teeth. Their incisors keep growing longer and longer throughout their entire life. They need to file their teeth down on hard plants like trees bark to keep them from growing too long.
Capybaras are social animals and live in large groups. A mother capybara gives birth to up to six babies at a time, though the average number of babies is four.
Capybaras can run, jump in long leaps and swim. In fact, they spend lots of time in the water, and even have webbed feet to help them swim. The water keeps capybaras cool during the hot day, and it provides aquatic plant food. They also use the water for protection. They can submerge below the surface to hide from predators such as jaguars, anacondas, and ocelots. A capybara's eyes, ears and nostrils are near the top of their head. This helps them breathe and keep watch for predators while swimming underwater. Still, they have to be alert at all times because many of its enemies are good hunters in water. When danger is near, capybaras can dive deep to the bottom of a riverbed and hold their breath for five minutes before returning to the surface for air.
