[4] Read the instructions and write a well-organized answer in English. (50 points) Virtual reality (VR)* refers to a high-quality simulation of reality created by a computer. Probably the most famous use for VR so far is gaming. But VR has also been used to improve society in various fields such as education, medicine, and engineering. Describe a single specific way that virtual reality can be used to improve society. Explain your idea in detail in about 100 English words. Notes: Virtual reality (VR)*: VR systems use special glasses that completely cover the user's eyes. These glasses show a very realistic picture of a world created by the computer. In addition, the systems can tell when the user moves their head, arms, and sometimes other body parts. So users can control the action by natural movement. Some systems even let users feel like they are touching things. Thus, VR systems can make users feel like they are really in another world. 〔答案〕 I suggest you to simulation with VR. For example, doctors can practice operation. I have the three reasons. First, VR's display is very real. So doctors can do as if real simulation. Second, every one can make simulation software. If you want add patients information to VR and study how to make software, you can make VR software to yourself. Third, medical professors can use VR simulation in lecture. If they do this, Students who want be surgeon in the future will reduce about operation's anxiety. In this way, VR have a lot of possibilities that useful of medical field. For these reasons, I suggest VR simulations.

A Makeover for Hoover Dam Hydropower has attracted increasing attention in recent years as a renewable type of clean energy. As long as a suitable water source is available, hydropower facilities are usually good investments, producing energy in a manner that generates far less air pollution and CO2 emissions than fossil fuels do. The most common way to generate hydropower is to trap water at a high elevation behind a dam so it can be released and used to spin turbines below, which, in turn, power electricity-producing generators. However, hydropower has its drawbacks. Droughts and increased water consumption have reduced the flow of many rivers. As rivers become shallower, the necessary volume of water for electricity difficult to maintain, and power supply and generation is dependability are negatively impacted. more Variability in water levels has particularly affected Hoover Dam, a mega-scale hydropower facility in the US state of Nevada. Built in the 1930s at enormous expense to control the frequently flooding Colorado River and maintain a water supply for farmland irrigation, the dam's hydropower capabilities were seen as a way to recover some of the costs of its construction over the long term. The dam's electricity-generating capacity, however, was challenged from the start by seasonal variability in water flow, and in recent years has been greatly reduced by droughts. Combining hydropower with other alternative energy sources, though, may offer a solution. Solar and wind plants can produce enormous amounts of electricity, but one serious downside is that the energy they produce is not available when there is little sun or wind. While conventional batteries can help with this issue, storing such tremendous volumes of electricity has long been a challenge. A recently proposed system for Hoover Dam could provide an answer, though. The plan suggests building a new pumping station that would be powered by both wind and solar. It would push water from the river back up to Hoover Dam, refilling the lake behind it. The water could be released anytime to power the dam's generators in order to reliably meet demand for electricity. Kelly Sanders, an engineering professor at the University of Southern California, is enthusiastic about the storage plan, saying, "We by the p replace fo solat als are st ons to the What is 1 Inst inves 2 WE dams 3 A neg sys 1 en

Read the passage and answer the questions that follow. (1). „Why do batteries matter? Look at all your electronic devices: from laptops to smartphones to Kindles or iPads, even your watch. Those electronics are getting more energy-efficient and require less energy than they used to. But as they do, people get greedy and want their capabilities to increase. The battery, or how much energy you can 05 store in a given volume and weight, is the defining factor in this whole field. Then there are electric cars. If we can make batteries with double the "energy TR2Z density of today's and drive the price below $200 per "kilowatt-hour (versus $300 to $800 today, depending on type and weight), we could have a car with a 300-mile range, even with the air conditioner or heater turned up, that would sell for $25,000 to $30,000. The 10 Department of Energy's goal is to get batteries to $150 per kilowatt-hour by the year 2020. 01 Finally, there are the "utility-scale batteries, which are very important for renewable TR28 energy. Wind and solar power are going to become more common. Wind is already the second-cheapest form of new energy, after shale gas, and it will become the cheapest 15 15 within a decade. Right now "utility companies get about 4 percent of their power from renewable sources other than "hydro- and that 4 percent is roughly all from wind. We may see a day when renewables make up 50, 60, 70 percent of the total supply of energy. Utility companies will need batteries to stabilize the flow of renewable energy into the *grid, and also require a better electrical control system to (3)do the switching. People 20 may have these batteries at their homes instead of generators. All of this would create a huge market. But the effects would be more profound. T There are mountainous places even in the U.S., like western Alaska, that will never be connected to the electric grid. There aren't enough people, and the distances are too great. There are many parts of South Asia like this, too. But they will have solar and 25 wind power - which, in 10 or 15 years, are going to be as cheap as any other form of energy, or cheaper. Once you have "storage systems, you can put a little "solar installation on your roof or "a plot of land, and then you will have your electric supply! It will be like cellphones' "leapfrogging the "land-line era. It will transform the prosperity of the world. 【Notes】 energy density エネルギー密度 (ここでは電池の容量を意味する) kilowatt-hour キロワット時 (1キロワットの機器を1時間使ったときの消費電力量) utility-scale 電力供給に使う規模の hydro utility company t storage 貯蔵 (ここでは電気を蓄えておくことを意味する) grid solar installation a plot of land 一画の土地 land-line 地上 (の電話) 線 by a factor of two (増減の幅が)2倍で (50pts.) leapfrog 〜を一足跳びにする
