DELTA’S KEY TO THE NEXT GENERATION TOEFL® TEST


ABOUT THE TEST

ABOUT THE TEST The Test of English as a Foreign Language® (TOEFL®) is a standardized test that measures the English proficiency of students who wish to enter college and university programs in the United States and Canada. The TOEFL is produced by Educational Testing Service (ETS), a professional test development organization in Princeton, New Jersey, USA.

THE TOEFL® iBT The Internet–based TOEFL (iBT) was administered for the first time in 2005. This new version of the TOEFL replaces the earlier computer–based test (CBT) and the paper–based test (PBT). The TOEFL iBT has four sections, which assess the language skills of reading, listening, speaking, and writing. The test is approximately four hours long, with one 10–minute break after the Listening section.

The content of the TOEFL iBT reflects the language that is used in real academic settings. The content is based on a collection of spoken and written language that Educational Testing Service obtained from college and university lectures, class discussions, office hours, service interactions, study groups, textbooks, and various course materials. The most important differences between the TOEFL iBT and earlier versions of the test are: note taking is permitted throughout the test speaking skills are assessed some questions involve integrated skills, such as reading–listening–speaking knowledge of grammar is not tested separately but is tested indirectly in all sections of the test The Speaking and Writing sections of the test include some tasks that integrate, or combine, language skills. For example, a student might read a passage, listen to a lecture, and then write or speak in response. The integrated–skills tasks reflect how people use language in real life; thus, they give academic programs a more realistic measure of how well prospective students will be able to communicate in an English– speaking environment.

SIX PRACTICE TESTS FOR THE IBT

ABOUT THE TEST In each section of the test, the number of points earned is converted to a scaled section score of 0 to 30. The four section scores are combined to obtain the total test score, which is on a scale of 0 to 120. The TOEFL iBT score report will show: a separate score of 0 to 30 for each of the four language skills a total test score of 0 to 120 The admissions office of an educational institution will look at a student’s TOEFL score to determine if the student’s English skills are adequate for enrollment in a specific program of study. There is no single passing score for all institutions; rather, each institution or program sets its own standards for admission. Generally, graduate programs require a higher score than do undergraduate programs. The scoring scale of the TOEFL iBT is different from the scoring scale for the computer–based TOEFL (CBT) or the paper–based TOEFL (PBT). The table below shows a general comparison of the three different scales.

THE TOEFL® ITP The TOEFL Institutional Testing Program (ITP) is a paper–based form of the test that academic institutions administer for their own internal use. Scores from the TOEFL ITP may be used only within the college, university, or language school that administers the test. Scores may not be sent to outside institutions. Like all other forms of the TOEFL, the institutional TOEFL evaluates the English proficiency of students who are pursuing academic studies. Institutions may require the TOEFL ITP for various reasons, such as placement in a program, assessment of progress, requirement for graduation, or practice for the TOEFL iBT. Beginning in 2007, the TOEFL ITP will have two sections, Reading and Listening, which will consist of questions from previously administered forms of the TOEFL iBT. The new TOEFL ITP will be approximately two hours long.

Reading 4 of 39

34 : 10

The Distribution of World Resources Which sentence below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information

1 Food cannot be grown in some regions because the soil is too poor. 1 Refugees are unable to produce food, and poor people cannot afford food. 1 People cannot survive solely on root crops, which are poor in nutrients. 1 Some people can relocate to find food, but poor people have nowhere to go.

The uneven distribution of food resources is a large and growing problem in the world today. Starvation is widespread in the Third World because of climate change, natural disasters, political turmoil, and wars –– all of which disrupt food production and cause mass migrations of refugees. People who are uprooted cannot grow food, and those who are poor cannot buy it. At the other end of the scale, modern industrial societies account for most of the consumption of the world’s resources, although within these societies the resources are distributed unevenly among people of different classes. Both wealthy societies and wealthy individuals consume most goods and services, but they also produce most of the world’s hazardous waste. Are there enough resources to go around? The question concerns our planet’s carrying capacity, that is, the number of people that Earth can support. Estimates

Reading 12 of 39

29 : 26

Look at the four squares [ ] that indicate where the following sentence could be added to the passage. Contingencies are events that might affect what you plan to do, but rarely are out of your control. Where would the sentence best fit? Click on a square to the passage.

[ ] to add the sentence

Even the best plans are rarely carried out without some problems. Good managers learn to deal with problems as they come up. They make decisions as they are needed and adjust plans when necessary. Flexible plans allow for several contingencies. For example, rain is a contingency that might affect the success of an outdoor event. Trying to move indoors at the last minute could be a disaster. Therefore, your plan should include a “rain plan.” You need to reserve some money and time for the unexpected. If you budget your money down to the last penny, you might not be able to take advantage of a bargain that you suddenly hear about. Similarly, if you schedule your time too tightly, you might not be able to deal with those "unexpected events" that always seem to happen.

Adding the sentence at the correct square will keep the paragraph coherent. Adding the sentence at an incorrect square will interrupt the logical flow of ideas from one sentence to the next. Reading 12 of 39

ABOUT THE TEST

LISTENING The Listening section of the TOEFL measures your ability to understand conversations and lectures in English. You will listen to several conversations and lectures and answer questions about them. You will be tested on your comprehension of the general ideas and supporting details of the conversations and lectures. You will also be asked to identify a speaker’s purpose in making a particular statement or to identify a speaker’s attitude toward a particular topic. The conversation topics reflect typical experiences of North American university students. The lecture topics are academic and come from various fields of study in the natural sciences, the social sciences, business, and the arts. All of the questions are based on what the speakers state or imply. You do not need special knowledge of the topics to answer the questions. In some forms of the TOEFL iBT, the Listening section will have two conversations and four lectures. In other forms, the Listening section will have three conversations and six lectures.

You will use headphones to listen to the conversations and lectures. You can change the volume of the sound at any time during the test. You may take notes on paper while you are listening. You may use your notes to help you answer the questions. However, at the end of the test, you must give all of your notes to the test supervisor. Your notes will not be scored. The Listening section takes approximately 60 to 90 minutes to complete. This includes the time that you spend listening to the directions, listening to the conversations and lectures, and answering the questions. A clock at the top of the screen shows how much time is left. The clock counts down only during your response time; it does not count down while you are listening to the conversations, lectures, and questions. You will hear each conversation and lecture only one time. You will both hear and see each question. You must answer each question before you can go on to the next question. You can change your answer as many times as you like—until you click on OK. When you click on OK, the computer will go to the next question. Once you have finished a question, you cannot return to that question or to any other previous question. There are six types of listening questions. For each type of question, you will use the mouse to click on one or more answers or to move text. Some of the questions have special directions, which will appear in a gray box. Most correct answers will earn one point, but some questions are worth two points.

ABOUT THE TEST Here is an example of a lecture, followed by the six types of listening questions.

Geology

(Narrator) Listen to part of a lecture in a geology class. While you are listening, you will see a picture of the class.

(Professor) After the water drains from a cave, a new kind of growth may begin. Delicate straws grow from the ceiling. Twisted fingers protrude from the walls and floor. Smooth mounds appear in pools. All of these amazing formations are called speleothems. They sometimes grow in sandstone and lava–tube caves, but most commonly we see them in limestone caves. Among the most interesting speleothems are stalactites and stalagmites. People always want to know: how do you keep straight… which is a stalactite and which is a stalagmite? There’s an easy way to remember. “Stalactite” is spelled with a “c” and it hangs from the ceiling. “Stalagmite” is spelled with a “g” and it grows up from the ground. Both stalactites and stalagmites begin with a drop of water on a cave ceiling. The ground– water seeping into the cave contains carbon dioxide from the atmosphere or the soil, as well as dissolved limestone that it picked up from the layers of rock above the cave.

DELTA’S KEY TO THE NEXT GENERATION TOEFL® TEST


ABOUT THE TEST

ABOUT THE TEST As a drop of water hangs from the ceiling, a tiny amount of carbon dioxide escapes—just like bubbles from a can of soda pop. Now the water drop can’t carry much dissolved limestone, and a tiny ring of stone called dripstone forms around its outside edges. The drop of water hangs for a moment, then it falls. Each drop of water adds another layer as it trickles down through the growing ring of dripstone. Eventually, the dripstone forms a slender tube. These slender, hollow tubes are called tubular stalactites, or—because they look like straws—soda–straw stalactites. They’re very fragile. As they grow, their own weight may cause them to break off and fall to the floor. Soda straws can grow into conical stalactites as dripstone builds up on the outside. Stalactites don’t grow very quickly… on average, only about a half–inch in a hundred years. The dripping water that hits the floor still contains some dissolved limestone. The impact of the water hitting the floor causes it to break into droplets, releasing the excess carbon dioxide. Then limestone crystals start to grow upward, forming stalagmites… starting with tiny finger–like structures, and eventually forming large, rounded domes up to ten meters tall and ten meters in diameter.

Then click on a different box. You must choose both correct answers to earn a point for answering the question correctly.
