最新的 GED Certification GED-Science 免費考試真題:

1. The International Space Station (ISS) is in orbit about 400 km (250 miles) above the surface of Earth. The ISS is a platform that will enable scientists to conduct a wide range of experiments and observations. A diagram of the ISS is shown at the left.

Which statement explains how materials get to the orbit of the ISS so that they can be assembled into the ISS?

A) Materials are carried into orbit by the Space Shuttle, and the astronauts assemble the ISS.
B) Huge cargo airplanes are used to carry materials to orbit where the ISS is built.
C) The material is made on the Moon, flown to Earth's orbit, and used to assemble the ISS.
D) Huge rockets carry the material into orbit and robots assemble the ISS.
E) Astronauts collect space debris and then use this material to assemble the ISS.

2. Scientists' studies have revealed that health is tied very closely to diet. Health organizations estimate that more than one-third of all cancer is caused by food and drink. The health of the heart and circulatory system is linked to these factors and to the amount of cholesterol in the bloodstream.
Cholesterol is a fatty, waxy substance. Although a certain amount is required for good health, excessive amounts of cholesterol cause arteries to clog.
Which meal and beverage is best for a person who is trying to reduce his or her cholesterol level?

A) cheese sticks, pears, salad, milk
B) hamburger, french fries, cola
C) steak, green beans, rice, coffee
D) pepperoni pizza, salad, fruit cocktail, cola
E) pinto beans, plain baked potato, apples, tea

3. Cholera is a disease caused by a bacterium that is transmitted by water, shellfish, and raw vegetables. The major symptom is severe diarrhea. Epidemics of cholera in the Americas, common in the 19th century, are much less frequent now with the advent of modern medicine and improved methods of hygiene.
However, in 1991, the number of cholera epidemics increased again in one South American country, causing over 4000 deaths.
The high number of cases of cholera in the South American country noted above was most probably due to which factor?

A) lack of variety in foods
B) poor water and sewage treatment
C) eating the wrong kinds of foods
D) prolonged smoking of cigarettes
E) widespread overuse of antibiotics

4. Bernoulli discovered that fast-moving air creates less pressure than does slow-moving air. He thought this seemed the opposite of what would be reasonable, but repeated experiments proved it to be true. He held a piece of paper up to his mouth, as shown below, and blew across it. The paper tilted upward. This happens because the faster moving air results in less pressure on top of the page, causing the greater pressure under the paper to push the paper upward.
Exhibit:

Based on the information, why can a smoky car interior be cleared out rapidly by lowering a window slightly while the car is moving?

A) Since there is more air outside the car than inside, there is more pressure outside.
B) The fast-moving air outside the window has less pressure than the air inside the car, so smoke gets pushed out the window.
C) The design of the interior of the car directs air flow in such a way that the smoke is pushed out the window.
D) The force of air from the heater or air conditioner pushes the smoke out.
E) The air inside the car is usually warmer than the air outside the car, so this warm air pushes the smoke out.

5. Anton Van Leeuwenhoek observed living cells using microscopes that he designed and built. His particular passion was working with and perfecting microscope lenses; and he kept all of his techniques secret to prevent other scientists or inventors from stealing his ideas. Leeuwenhoek recorded his microscope observations, which were helpful to later scientists.
Which statement best describes Leeuwenhoek's scientific contribution?

A) He designed and built early microscopes and used them to observe microscopic organisms.
B) He classified thousands of animals and plants.
C) Most modern knowledge about meteorology and astronomy can be traced to his observations.
D) He influenced the development of modern chemistry.
E) His work centered on making many types of antibiotics and vaccines.
