TAILIEUCHUNG - The complete guide to the toefl test part 93

The test is not "computer adaptive" (unlike the previous computer-based version). In other words, if you answer a question correctly, the next item is not more difficult, and if you answer a question incorrectly, the next question is not easier. All test-takers see the same question during each administration of the test. | 620 Section 4 Guide to Writing Task 5 In the last few weeks we ve been seeing letters to the editors in the campus newspaper from some of the faculty of the astronomy department. It seems that some of the astronomers who work nights at the Hodgkins Observatory are upset because the surrounding campus as well as our city streets are too well lighted. This makes it difficult the astronomers say for them to observe the stars and conduct their experiments. Well I am sorry for these scientists. However if you ask any of the professors in the department of criminology I m sure they will tell you that bright lights serve a useful purpose for all of the students and for all of the residents of our city. Studies show that good lighting stops crime. It s as simple as that. We need more nighttime light on our campus and on our streets not less.

Q Lesson 22 Summarizing Paraphrasing Citing and Synthesizing 621 Notes on the lecture Summary Paraphrase of the lecture Task 6 Until the late 1950 s protozoa were considered the simplest forms of animals. The name protozoa means first animal. In some ways they do resemble animals. Some protozoa move about freely and can be seen eating food. Other protozoa however have characteristics of plants. Some cannot move on their own. Some contain chlorophyll. This created a problem for biologists. Larger organisms can easily be classified into one of the two kingdoms plant or animal. With micro-organisms such as protozoa the system breaks down. However since organisms had to be classified as either plants or animals protozoa were considered animals.
