课后阅读训练 十三Unit 4Period 1. 阅读理解AGlobal warming is the process of earths atmosphere heating up. Over the last 100 years, the average temperature of earths atmosphere has gone up 1 degree Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earths climate. Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment and so on. Many scientists believe that the biggest cause of global warming is new human technologies that release greenhouse gases into the atmosphere. The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, make it hard for heat energy to go into space. In the past, the climate didnt change much because nature produced just the right amount of greenhouse gases to deal with it. Today, most scientists are pretty sure that the rising temperature cant be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance. The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise. Over the past 100 years, the sea level has risen 68 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts. 【语篇概述】本文主要讲述了全球变暖的原因及影响。1.

But rather than run in fear from it, weve welcomed it into our homes: Pepper, the“emotional robot, ”sold out within a minute of going on sale. Created by Aldebaran Robotics and Japanese mobile giant SoftBank, Pepper went on sale to the general public in Japan on June 20. It is“the first humanoid(类人的)robot designed to live with humans, ”Aldebaran says on its website. Pepper costs about $1, 600. And like all good mobile products, theres a $120 per month data fee, as well as an $80 per month damage insurance fee. According to a news report, Pepper can pick up on human emotions and create its own using a“multi-layer neural(神经的)network. ”Peppers touch sensors and cameras are said to influence its mood, which is displayed on the tablet-sized screen on its chest. Pepper will sigh when unhappy, and can go around your house recording your familys daily activity. Aldebaran says Pepper can feel“joy, surprise, anger, doubt and sadness, ”but it doesnt say how strongly it can feel these emotions. What happens when Pepper is having a bad day? Will it, like many humans, become uncooperative? Will it ask for some time alone? What happens if it knows that its purpose in life is just to take part in small talk? Thankfully, Pepper is only about four feet tall, with roller balls instead of legs, so if it is angry with and even turns on its owners, youll be safe if you can make it upstairs. Aldebaran says in reality, theyre probably quite
