Historically, schools in the United States have borrowed the European system of school organization, a system that separates students into grades by chronological age. In general, children begin formal schooling at the age of six in what is referred to as the first grade. For the most part, students progress through twelve grades; however, some students who do not meet minimum requirements for a particular grade may be asked to repeat the year.
Graded schools are divided into primary grades, intermediate grades, and secondary grades. Primary education includes grades 1 through 5 or 6, and may also provide kindergarten as a preparation for first grade. Referred to as elementary school, these grades are usually taught by one teacher in a selfcontained classroom. Intermediate grades begin with grade 6 or 7 and offer three years of instruction. At this level, teams of teachers may collaborate to provide subject-based classe

Do computers think It isn’t a new question. In fact, Alan Turing, a British mathematician, proposed an experiment to answer the question in 1950, and the test, known as the Turing Test, is still used today. In the experiment, a group of people are asked to interact with something in another room through a computer terminal. They don’t know whether it is another person or a computer that they are interacting with. They can ask any questions that they want. They can type their questions onto a computer screen, or they can ask their questions by speaking into a microphone. In response, they see the answers on a computer screen or they hear them played back by a voice synthesizer. At the end of the test, the people have to decide whether they have been talking to a person or to a computer. If they judge the computer to be a person, or if they can’t determine the difference, then the machine has passed the Turing Test.

The jet stream is an irregular band of wind that occurs in high altitudes at about 20,000 feet, that is, between 6 and 9 miles above the surface of the Earth. Consequently, the jet stream wanders near the top of the Earth’s troposphere, and, coincidentally, that is exactly where most of the Earth’s weather patterns occur. It is helpful to think of the jet stream like a river of air that occurs at several different locations, but in general flows from west to east over the middle latitudes. Technically, to be called a jet stream, the winds should be moving faster than 57 miles an hour, but it can have average core speeds of 190 miles per hour, and in the winter, when the jet stream is strongest, winds have been clocked at 300 miles an hour. For the most part, the winds are stronger in the winter because during the winter months the surface temperature contrasts more with the temperature in the troposphere. To put that another

TOEFL Reading Passage 1 The Snake’s Forked Tongue
1. One of the most intriguing physical characteristics of snakes is their forked tongues. While this trait is also shared by some types of lizards, all snake species exhibit split tongues, which usually have a more
pronounced fork than those of lizards. Any observer of snakes has no doubt noticed that they often stick their tongues out of their mouths, flick them up and down in the air, and then retract them. In fact, due to a slight indentation in the upper jaw, many species can protrude their tongues without even opening their mouths.
2. The explanation for this behavior remained unknown for centuries, giving rise to many
folk superstitions. For example, the forked tongue has become synonymous with deceit, from the idea that two separate tongues would enable a creature to voice two contrasting ideas at the same ti

TOEFL Reading Passage 2 The Mediterranean’s Killer Algae
1. Today there are many invasive species threatening ecosystems all over the world, but few are of as much concern as Caulerpa taxifolia.This species of green algae grows in long, thin blades similar in appearance to sea grass. Each individual alga is single-celled, with a length of up to a meter, they are some of the largest cells in the world. Algae contain chlorophyll and produce their own food through photosynthesis. Also they reproduce asexually, meaning that if an alga is cut in two each half wilt develop into a whole new organism.
2. Caulerpa taxifolia’s native habitats are the tropical waters of the Caribbean, south Pacific, east Atlantic, and Indian Ocean. However, in the 1970s, a new strain was bred in Europe to decorate exhibits in saltwater aquariums. The strain proved useful for this purpose, for it was able to g

TOEFL Reading Passage 1 Two Types of Social Groups
1. One of the most basic elements of human life is the way in which we form social groups and interact with the members of those groups. According to sociologists, no one is ever entirely separate from the social networks that surround him or her, and the groups we belong to play an enormous role in determining how we see ourselves and our world. Early American sociologist Charles H. Cooley(1864-1929) defined two principal categories of human groupings, and his ideas are still widely accepted today. He termed them primary and secondary, based on the kinds of relationships individuals in the group share with each other.
2. In primary groups, we form what Cooley referred to as primary relationships. These are marked by strong, long-lasting emotional ties, feelings of intimacy and genuine concern for the well-being of the other person or people. Intan
