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. Language Arts
Choose the sentence that is written correctly.
- a.Neither the manager nor the employees were ready for the audit.
- b.Neither the manager nor the employees was ready for the audit.
- c.Neither the manager nor the employees is ready for the audit.
- d.Neither the manager or the employees were ready for the audit.
答案: a
解析: With 'neither/nor,' the verb agrees with the nearer subject, which is 'employees' (plural), so 'were' is correct. The correlative conjunction requires 'nor,' not 'or.' This is a standard subject-verb agreement rule for compound subjects.
- 2. Mathematical Reasoning
A shirt originally costs $40 and is on sale for 25% off. What is the sale price?
- a.$30
- b.$10
- c.$15
- d.$35
答案: a
解析: A 25% discount on $40 is $10, so the sale price is $40 − $10 = $30. You can also multiply $40 by 0.75 to get $30 directly. The discount is subtracted from the original price.
- 3. Science
What do we call the variety of living organisms in an ecosystem?
- a.Community
- b.Climate
- c.Population
- d.Biodiversity
答案: d
解析: Biodiversity is the range of different species living in an area. A community is all the populations living together in that area — a related idea, but it names the assemblage rather than its variety. A population is a single species, so it cannot describe variety at all. And climate describes long-term weather patterns, not living things. High biodiversity tends to make an ecosystem more stable.
- 4. Language Arts
Read: 'City buses ran every ten minutes during the strike. Ridership rose by a third. When normal service returned, the buses came every twenty minutes again and ridership fell back.' The main idea of this passage is that—
- a.the city should hire more bus drivers
- b.strikes are good for public transit
- c.more frequent service attracts more riders
- d.bus riders dislike waiting in the cold
答案: c
解析: Every sentence links how often buses came to how many people rode them, and the passage rises and falls with that one relationship, which is what makes it the main idea. Nothing here praises strikes; the strike is only the occasion that changed the schedule. Cold weather is never mentioned. And hiring more drivers is a recommendation the passage does not make.
- 5. Language Arts
Read: 'Studies suggest that walking thirty minutes a day may reduce the risk of heart disease.' Compared with a claim that walking prevents heart disease, this statement is—
- a.identical in meaning to the stronger claim
- b.an opinion rather than a report
- c.more cautious and easier to defend
- d.stronger and harder to support
答案: c
解析: The words 'suggest,' 'may' and 'reduce the risk' all limit what is being asserted, which makes the claim easier to back with real findings. A stronger claim would be harder to defend, not this one. The two are not identical: prevention and risk reduction are different claims. And reporting what studies indicate is not a statement of preference.
- 6. Mathematical Reasoning
A meal costs $45 and the diner leaves an 18% tip. How much is the tip?
- a.$81.00
- b.$0.81
- c.$5.31
- d.$8.10
答案: d
解析: Eighteen percent of $45 is 0.18 × 45 = $8.10. Moving the decimal one place too far left gives $0.81. Moving it the other way gives $81, which is more than the meal. And $5.31 would be about 11.8 percent, a rate the question did not give.
- 7. Mathematical Reasoning
What is the slope of the line y = −(1/2)x + 4?
- a.−1/2
- b.−4
- c.4
- d.1/2
答案: a
解析: The coefficient of x is the slope, and here it is negative one half, meaning the line falls as it moves right. Dropping the negative gives a line that rises instead. The 4 is the y-intercept. And −4 is that intercept with the sign changed.
- 8. Science
A person whose food supplies more energy than the body uses over a long period will most likely—
- a.lose weight through faster digestion
- b.store the excess as body fat
- c.convert the excess into vitamins
- d.excrete all of the excess energy
答案: b
解析: Energy that is taken in and not spent is stored, mostly as fat, which is the physical meaning of a sustained surplus. The body does not simply discard surplus energy; that is the whole reason a surplus matters. Vitamins are nutrients obtained from food and cannot be manufactured out of excess calories. And digestion does not speed up enough to make a surplus disappear.
- 9. Science
Earth has seasons mainly because—
- a.its axis is tilted as it orbits the Sun
- b.its distance from the Sun changes greatly
- c.it spins more slowly in winter months
- d.the Sun's output rises and falls yearly
答案: a
解析: The tilt means each hemisphere leans toward the Sun for part of the year and away for the rest, changing the angle of the sunlight and the length of the day. Earth's distance from the Sun does vary slightly, but far too little to drive the seasons, and it would give both hemispheres the same season at once. The Sun's output is nearly steady. And the rotation rate does not change with the calendar.
- 10. Social Studies
A group that gathers voter signatures to put a proposed law directly on the ballot is using—
- a.an impeachment petition
- b.the initiative process
- c.the recall of an official
- d.a legislative referendum
答案: b
解析: An initiative lets citizens themselves place a measure before the voters by petition, and many states provide for it in their constitutions. A recall also begins with signatures but its object is removing an officeholder, not enacting a law. A referendum is referred to the voters by the legislature rather than gathered by citizens. And impeachment is a legislative proceeding with no petition or ballot step.
