　　综合写作 历史 重复2017.9.30

　　主题：维京人离开格陵兰岛的原因

　　阅读

　　First, climate change might have made farming in the colony impossible, exposing the Vikings to starvation. In the tenth century, the North Atlantic was somewhat warmer than it is today; this, historians believe, is what allowed the initial success of the Greenland colony. When the coast of Greenland was warmer, the Vikings were able to grow crops and raise animals there. However, the regional climate gradually cooled, making farming more difficult. Without a reliable source of food, the Vikings were eventually forced to abandon their colony.

　　Second, the Vikings could have been driven out by other groups of people who also inhabited Greenland. Some of these groups came to Greenland before the Vikings did. The Vikings had to compete with them for the land and resources available in the region, and conflicts may have resulted. The Vikings likely would have been at a disadvantage when defending against populations that had been in Greenland longer and were better established there.

　　Third, a decline in trade with Europe could have caused the collapse of the Greenland colony. The colony initially traded directly and extensively with Europe, exchanging valuable animal products, such as walrus tusks, for European goods, such as metal tools. Later, however, the colony came under the control of Norway. The government of Norway forbade the colonists to trade with European traders and demanded that all Greenland products be transported to Norway first. The loss of direct trade with Europe would have made it much more difficult for the Greenland colonists to obtain the supplies they needed.

　　听力

　　First, the starvation theory. Even if agriculture became difficult, the Vikings still had an excellent source of food, the ocean. Historians used to think that the Vikings were unable or unwilling to fish, since they preferred to farm. But new evidence contradicts that idea. On fish. Since the supply of fish was not affected by the cooling climate. It seems unlikely that the Greenland Vikings would have starved or abandoned the colony for lack of food.

　　Second, it's unlikely that a conflict with another group forced the Vikings to leave. Archaeologists examining the remains of the colony found that the Vikings took all of the valuable objects away with them when they left the colony. This shows that the Vikings left the colony in an orderly way and had plenty of time to carefully pack their valuable belongings. If the colony had been attacked, the Vikings would have been forced to leave very quickly and would not have had time to pack up their valuables.

　　Third. A decline in trade with Europe. Well, even though official trade had to be conducted through Norway, there was still plenty of unofficial illegal trade. Many European traders ignored Norway's rules and continued to sail directly to Greenland to trade there. In fact, this illegal trade happened so frequently that the king of Norway himself complained about it. You see, we've discovered an actual document in which the king of Norway complained that the Greenland Vikings were trading so extensively with other countries that they had no good products left over to transport to Norway. All of this illegal trade probably provided enough supplies to the Greenland colony.

　　Doctor Achebe: Today, we are going to discuss how to encourage young adults (aged 18-24) to actively engage in culture and art-related events. Some people propose that governments should consider offering special funding to support this age group so that they can use the funds to experience a variety of cultural, artistic, and musical activities. This can not only allow them to experience different forms of culture but also develop a deeper appreciation for the arts. Do you think this is a good idea? Why or why not?

　　Kelly: I don't think it's a good idea, because young adults might spend the government money on events related to their friends only, such as attending a band live show, however, doing this might not help them explore different cultures and arts.

　　Paul: Band live shows are a good way to experience culture and art, so participating in them can certainly help young adults learn more about music and art. By watching or being part of a band show, young adults can gain a deeper understanding of music culture, feel the beauty of art and thus understand the world in new ways.

　　综合写作 天文学 重复2024.7.10

　　主题：在撒哈拉沙漠发现的陨石是否来自水星（Mercury）

　　阅读

　　Color

　　The first clue about the meteorite's origin was its unusually light color. This quality suggested that the meteorite came from a planet with a thin, rocky outer crust and a hot interior core. The nearest planets fitting this description are Mercury, Venus, and Mars. Scientists ruled out Venus because its thick atmosphere would burn up any outgoing rocks. As for Mars, the Saharan meteorite looks nothing like any other meteorites known to be from Mars, so scientists ruled out Martian origins as well. That leaves Mercury as the most likely candidate.

　　Magnetism

　　Second, one of the unique features of Mercury is that it has very low magnetism. Meteorites from other sources typically have very high magnetic intensity, but tests on the Saharan meteorite showed that it had the lowest level of magnetism ever measured in any meteorite. That level of magnetism almost perfectly matches that of Mercury's magnetic field. This close match to one of Mercury's unique traits provided strong evidence of its origin on Mercury.

　　Speed

　　Still, one puzzle remained. Mercury is the planet nearest to the Sun, so it was unclear how a rock from Mercury could travel all the way to Earth against the gravitational pull of the Sun. However, astronomers demonstrated through computer simulations that a collision with a space object could cause rocks to break off from Mercury at speeds fast enough to move away from the Sun's gravitational pull. It is therefore possible for a meteorite to make the journey from Mercury to Earth.

　　听力

　　Earth. It's true that the meteorite's light color suggests that it came from a planet with a rocky crust. But there are other options besides Mercury, Venus or Mars. You see. Early in the formation of the solar system, there were these objects, called protoplanets. The protoplanets had a crust and a core like today's planets. Most protoplanets do not exist anymore, however, because they kept colliding with one another. During these collisions, pieces of block broke off and were thrown into space. So the meteorite in the Sahara desert may not have come from any planet that's still in existence. Instead, it may be a piece of a protoplanet that was broken off long ago.

　　Second yes, the low magnetism matches mercury's profile, but what's more important is the chemical composition of the meteorite. And that does not match up with the features of mercury. You see, the meteorite contains a large amount of a hard greenish mineral called pyroxine. And we don't know where that pyroxine came from, because studies have not found large amounts of that substance on mercury. So even though the magnetism data match, other features like the green thyroxine do not match.

　　Finally, the journey from mercury to earth against the sun's gravitational pull, while possible, would require a lot of initial speed and energy. The rock would need to leave mercury at speeds of over nine kilometers per second, and that would cause it to become extremely hot. That type of heat would leave detectable signs on the rock. For example. The heat would cause some of the rock to melt to form glass, which means that we would find glass on the surface of the meteorite. But the Sahara meteorite doesn't have any glass. So it seems doubtful that it came from mercury.

　　Doctor Achebe: This week, we’ll talk about a problem many working parents face: being exhausted from juggling jobs and childcare. Some struggle with strict work schedules, high daycare costs, or feeling guilty about missing time with kids. Let's brainstorm solutions. What do you believe is the most effective measure employers or governments could implement to better support working parents?

　　Kelly: Governments should help pay for childcare. Right now, childcare costs are way too high many parents work overtime just to afford it. If taxes covered part of daycare bills, parents could work regular hours or even take classes to get better jobs. In my neighborhood, many moms quit jobs because daycare cost more than their paychecks.

　　Paul: I believe that companies offering flexible hours is a key solution for supporting working parents. Rigid schedules often clash with family responsibilities, making it hard to find a balance. If employers allowed taking shifts or remote workdays, parents could handle emergencies without stress.

　　范文：

　　From my perspective, offering flexible work arrangements, such as remote work options or adjustable hours, is an effective measure to take. This is because it allows parents to better manage their time. For example, if a parent can work from home or adjust their hours, they can attend to their children’s needs, such as school drop-offs or doctor’s appointments, without sacrificing productivity. This reduces the stress of adhering to a strict 9-to-5 schedule and minimizes the guilt associated with missing important moments in their children’s lives.

　　Also, parents may no longer need to rely on expensive daycare services if they can work from home and supervise their children simultaneously. This financial relief is especially crucial for low-income families who struggle with the high costs of childcare. Therefore, flexible work arrangements are a practical and effective solution that benefits working parents, employers, and society as a whole.
