【正文】 Fortunately, there are several irrigation technologies that are more efficient than the poorly controlled and highly wasteful flooding methods. They range from sprinkler systems to drip irrigation. In sprinkler systems, water is sprayed over crops, and this provides an even distribution of water. New precision sprinkler technologies have greatly improved our ability to deliver water exactly when and where it’s needed. However, sprinkler systems are also a form of surface irrigation, and just as in other surface methods, some of the water is still lost to evaporation. Some forms of irrigation use water more efficiently than others. The efficiency of water use varies by region, crop, agricultural practice, and technology. The least efficient types of irrigation are the surface methods. Your reading really didn’t go into this, but think of how much water it takes for a traditional surface method like field flooding. It takes a lot of water to flood a field. The water collects into ponds or basins, but then most of it either evaporates into the air or passes down through the soil into groundwater. This means that, in lots of places, less than half of all the water applied to a field is actually used by the crop. The rest is lost to evaporation or to groundwater. All of the flooding methods generally waster a lot of waterwater that could otherwise be used for other purposes. One thing that really concerns water resource analysts is how much water agriculture uses. Agriculture uses a lot of water, more than all other waterusing sectors of society. One of our greatest concerns is the very high use of water by irrigation. This is because, in most cases, the water used for irrigation can’t be used afterward for other purposes, such as water supply for homes or industry.

This pattern. she says is characteristic of non endothermic aanimals.Thus it can be inferred that the professor challenges the passage by giving reasons as to why she thinks that the dinosaur is not an endotherm. 八、A reading passage like the following will appear on your puter screen. You will have 3 minutes to read the passage.Finally, the mystery of the panel consisting of patches glued together is also solved in the lecture. Actually, the wood panel was later enlarged to make it more grand and valuable, but the original painting was painted on a single panel, as Rembrandt would have done it. Furthermore, the wood is of the same tree used in other Rembrandt paintings, like the SelfPortrait with a Hat”.All this information points to Rembrandt as the painter of the controversial painting.七、關(guān)于恐龍是否是恒溫動(dòng)物The professor actually contradicts the statements made in the passage. She is of the view that dinosaurs are not endotherms . they were not able to keep their body temperature at a constant rate.s fluoride39。 evaluations.Lastly, the speaker argues that the school does not have to follow the trend of inflated grades invariably. The reading argues that if the school does not follow the trend, their students will be discriminated, the lecture says that this problem can be solved by providing a weighted relative score. This score will pinpoint a student39。s concerns that low grades will adversely affect teachers39。三：網(wǎng)絡(luò)問(wèn)卷（web based survey）reading網(wǎng)絡(luò)問(wèn)卷相對(duì)傳統(tǒng)問(wèn)卷的優(yōu)勢(shì)，所以調(diào)查結(jié)果就更為準(zhǔn)確（邏輯錯(cuò)誤：參加人多并不代表范圍廣，也不能保證效果好），填寫和收集問(wèn)卷更加方便簡(jiǎn)單lecture反駁網(wǎng)絡(luò)問(wèn)卷的優(yōu)勢(shì)（biased），因?yàn)椴皇撬腥硕紩?huì)上網(wǎng)，中老年人上網(wǎng)會(huì)比較少，而年輕人上網(wǎng)比較多，因?yàn)橐粋€(gè)好的網(wǎng)絡(luò)問(wèn)卷需要一個(gè)團(tuán)隊(duì)的大量工作（提出新的證據(jù)：網(wǎng)絡(luò)問(wèn)卷也需要成本和人力資源），會(huì)得到不正確的信息，容易混淆視聽(tīng)。 reading time is a benefit.The speaker begins by stating that merely pronouncing the words and story for the children will not provide adequate learning experiences.
