双语文摘 | 美国用来测试公众科学素养的10个简单问题


Question 1:TRUE OR FALSE? The center of the Earth is very hot.
问题1:判断对错 地球的中心非常热。

The correct answer...True.Scientists estimate that Earth’s core is more than 10,000 degrees Fahrenheit — nearly the temperature found on the surface of the Sun.

Question 2:TRUE OR FALSE? The continents have been moving their location for millions of years and will continue to move.
问题2: 判断对错 地球上各大洲的位置数百万年来一直在移动,它们会继续移动。

The correct answer...True.Plate tectonics is the science of how continent-size slabs of crust form Earth’s outermost layer and constantly move and regenerate. Most move less than a couple inches per year, according to Pacific Northwest Seismic Network, though the process may be essential to making a rocky planet habitable to life.

Question 3: Which is correct?A: The Earth goes around the Sun.B:The Sun goes around the Earth.
问题3: 选择题 以下哪个说法正确:A.地球绕着太阳转。B.太阳绕着地球转。

The correct answer...We know this is true on a basic level because we can see the position of the stars change over time. The space age has also required us to intimately understand this fact — and acknowledge our puny existence in the cosmos via stunning pictures of Earth from afar.

Question 4: TRUE OR FALSE? All radioactivity is man-made.
问题4: 判断对错 所有辐射线都是人造的。

The correct answer...Natural radiation is everywhere, especially in space. Small amounts are present in soil, water, and vegetation. Even a portion of the potassium found in bananas is radioactive.

Question 5:TRUE OR FALSE? Electrons are smaller than atoms.
问题5:判断对错 电子比原子要小。

The correct answer...True. Electrons are much less massive than the protons and neutrons that make up the cores of atoms.

Question6: TRUE OR FALSE? Lasers work by focusing sound waves.
问题6:判断对错 激光的原理是把声波集中。

The correct answer...False. Lasers concentrate light waves, not sound waves.

Question7: TRUE OR FALSE? The universe began with a huge explosion.
问题7:判断对错 宇宙始于一次巨大的爆炸。

The correct answer...True. This is the best theory that we have as to how the universe began: a point of infinite density at the beginning of the universe began to expand and created the galaxies, planets, and stars that we see — still in motion — today. People call this "the Big Bang," though it’s not technically an explosion.

"For an explosion to occur, it requires per-existing space and the material will be distributed or scattered in that space. For example, a star explodes and distributes material in the space," Nabin Rijal, a PhD student in nuclear astrophysics Florida State University, wrote in an email to Business Insider. "The Big Bang is very different than that. It is the expansion of space itself. Materials (elementary particles-antiparticles) are created in the process of expansion. [...] So, calling it an explosion would be wrong."

Question8: TRUE OR FALSE? It is the father’s gene that decides whether the baby is a boy or a girl..
问题8: 判断对错 婴儿是男是女由父亲的基因决定。

The correct answer...True. Sex is determined by two chromosomes, and sperm carries one of them: either an X (female) chromosome or a Y (male) chromosome. Whichever sperm makes it to the egg first to join an X chromosome in the mother’s egg determines the baby’s sex. (XX is a girl and XY is a boy, anatomically speaking.)

Question9: TRUE OR FALSE? Antibiotics kill viruses as well as bacteria.
问题9: 判断对错 抗生素既能杀死细菌也能杀死病毒。

The correct answer...False. Antibiotics only kill bacteria, not viruses.

Question10: TRUE OR FALSE? Human beings, as we know them today, developed from earlier species of animals.
问题10: 判断对错 我们今天所说的人类是从早期动物物种发展而来的。

The correct answer...True. Fossils in the ground, genetic studies, and other research over the past century has shown again and again that evolution not only gave rise to species like humans, but will continue to shape the forms of our descendants.
