When【小题1】(talk) about the two genders (性别), people often say that men are from Mars and women are from Venus. It is true 【小题2】men and women are different in many ways.

However, many of these differences in character can 【小题3】 (explain) by differences between the brains of men and women. For example, a study 【小题4】 (lead) by a British psychologist in 2012 found men's brains are, on average, 10 percent bigger than women's brains. But Lise Eliot, a professor at【小题5】Medical School of Chicago University, doesn't think the brain differences can explain personal features. She found that the brain differences mean nothing.

So, if it's not in the brain, what is it that makes males and females behave【小题6】 (different)? The answer may lie in socialization. In the past, many gender 【小题7】 (study) ignored a person's social background and upbringing. Take former Harvard University president for example. According to a 1970 research that showed men 【小题8】(beat) women 13-to-one, he thought men were 【小题9】 (good) at science subjects. 【小题10】, another study found that if females were given more opportunities to study science subjects, the ratio would drop to three-to-one.

Earthquake -proof (抗震的) buildings

There are a number of ways 【小题1】 buildings can be made strong enough to stand up to earthquakes. The simplest way is to make them much 【小题2】 (strong). A building strong enough not 【小题3】 (destroy) by a large earthquake, however, would probably look more like a bunker (地堡) than a nice place to live 【小题4】

So engineers have looked for other ways. One is to make the building that can swing (摇摆) from side to side. 【小题5】 is to design it so that it doesn't sit directly on the ground but on something that allows it to move a bit with the earthquake. If only a small part of a building 【小题6】 (fall) down in an earthquake, damage can be 【小题7】 (great) reduced, so buildings are often designed to do this as well.

However, 【小题8】 (make) new earthquake -proof buildings is expensive, but with the 【小题9】 (develop) of science and technology more efforts will be made to solve 【小题10】 problem in the future.

Water on the Moon

NASA has confirmed the presence of water on the moon’s sunlit surface, a breakthrough 【小题1】(suggest) the chemical compound that is vital to life on Earth could be distributed across more parts of the lunar surface than the ice that 【小题2】(find) previously in dark and cold areas.

“We don’t know yet if we can use it as a resource, ” NASA Administrator Jim Bridenstine said, but he added that learning more about the water is still crucial.

The discovery comes from the space agency’s Stratospheric Observatory for Infrared Astronomy, or SOFIA- a 【小题3】 (modify) Boeing 747 that can take telescope high1 into Earth’s atmosphere, 【小题4】researchers may peer at objects in space with hardly any visual disturbance from water vapor. To detect the molecules, SOFIA also used a special camera to distinguish between water’s specific wavelength of 6. 1 microns and that of its close chemical relative hydroxyl, or OH.

The data confirm 【小题5】experts have suspected, that water might exist on the moon’s sunny surface, though the form of it shall not be 【小题6】 (obvious)detected. Experts will now try to figure out exactly how the water came to form and why it persists.

“Data from this location reveal water in concentration of 100 to 412 parts per million trapped 【小题7】 a cubic meter of soil, ” NASA said in a release about the discovery. “ 【小题8】 without a thick atmosphere, water on the sunlit lunar surface should just be lost to space, ” said Casey Honniball, the lead author of a study about the discovery, “somehow we’re actually seeing it. ”

There are several possible 【小题9】 (explain) for the water’s presence, including an interesting yet reasonable one 【小题10】(claim) its origin to the stony micro objects from space. Small balls of glass from that process could trap water, according to the researchers’ paper.
