样题与解析
以下是本题库中的部分真题与完整解析。完整题库请用上方的刷题工具。
- 1. Arithmetic Reasoning
A train travels at a constant speed of 60 miles per hour. How long will it take to travel 180 miles?
- a.3.5 hours
- b.2 hours
- c.4 hours
- d.3 hours
答案: d
解析: Time equals distance divided by speed. Dividing 180 miles by 60 miles per hour gives 3 hours. Keeping the units consistent lets the miles cancel and leaves hours.
- 2. Paragraph Comprehension
A budget is a plan for spending money. By listing income and expenses, a budget helps a person avoid spending more than they earn. The main purpose of a budget, according to the passage, is to:
- a.borrow more money
- b.increase a person's income
- c.plan spending and avoid overspending
- d.eliminate all expenses
答案: c
解析: The passage defines a budget as a spending plan that lists income and expenses to prevent overspending. The correct choice captures this purpose. The others are not stated.
- 3. Electronics Information
A device that stores electrical charge is a:
- a.inductor
- b.resistor
- c.transformer
- d.capacitor
答案: d
解析: A capacitor stores electrical energy in an electric field between two plates. A resistor limits current, while an inductor stores energy in a magnetic field.
- 4. Arithmetic Reasoning
A mechanic charges $85 for the first hour of labor and $60 for each additional hour. What is the labor charge for a job that takes 5 hours?
- a.$265
- b.$325
- c.$385
- d.$425
答案: b
解析: The first hour costs $85 and the remaining four hours cost $60 each, so 4 x $60 = $240. Adding $85 + $240 gives $325.
- 5. Arithmetic Reasoning
A shipment of 1,250 items has a defect rate of 4 percent. How many items are not defective?
- a.1,200 items
- b.1,206 items
- c.1,150 items
- d.1,246 items
答案: a
解析: Four percent of 1,250 is 50 defective items, so 1,250 - 50 = 1,200 are good.
- 6. Word Knowledge
Prudent most nearly means
- a.generous
- b.wealthy
- c.sensible
- d.stubborn
答案: c
解析: A prudent decision shows good judgment and forethought about consequences.
- 7. Paragraph Comprehension
Coral reefs cover less than one percent of the ocean floor but shelter roughly a quarter of all marine species. The coral animal builds a stone skeleton, and generations of skeletons stack into a structure full of crevices. It is the crevices, more than the coral itself, that make the reef so crowded. The passage attributes the variety of reef life mainly to
- a.the many hiding places
- b.the warmth of the water
- c.the clarity of the water
- d.the coral animal's diet
答案: a
解析: The final sentence says it is the crevices, more than the coral itself, that make the reef so crowded.
- 8. Mathematics Knowledge
What is the distance between the points (1, 2) and (7, 10)?
- a.14 units
- b.100 units
- c.10 units
- d.8 units
答案: c
解析: The horizontal change is 6 and the vertical change is 8, so the distance is the square root of 36 + 64 = 100, which is 10.
- 9. General Science
A solar eclipse occurs when
- a.the Earth passes between the moon and the sun
- b.the moon moves into the Earth's own shadow
- c.the moon passes between the Earth and the sun
- d.the sun passes behind the far side of Earth
答案: c
解析: In a solar eclipse the moon blocks the sun from part of the Earth's surface. When the moon moves into Earth's shadow instead, the result is a lunar eclipse.
- 10. Mechanical Comprehension
A 180-pound crate hangs from a 10-foot pole carried by two workers at its ends. If the crate hangs 3 feet from the first worker, how much of the load does that worker carry?
- a.126 pounds
- b.90 pounds
- c.54 pounds
- d.150 pounds
答案: a
解析: Taking moments about the far worker, the near worker's share is 180 x 7 / 10 = 126 pounds. The worker closer to the load always carries more of it.
