Over-dried Earth

The south-west of the United States, together with some parts of Mexico across the Rio Grande, is one of the driest parts of the North American continent. But, over the past two decades, even that expected dryness 【1】 (take) to the limit. According to Park Williams, who works at Columbia University’s Lamont-Doherty Earth Observatory, the current lack of rainfall in the area constitutes a megadrought of a severity 【2】(see) on only four other occasions in the past 1,200 years.

Dr Williams studies the annual growth rings of 1,586 ancient trees, in order to reconstruct soil-moisture patterns going back to 800 A.D. During warm, wet years trees grow fast, producing wide rings. During cold, dry 【3】 they grow more slowly, producing narrow rings. During a drought, a tree 【4】 not grow much at all.

【5】they describe in this week’s Science, the team identified dozens of droughts over the centuries in question. But four stood out. They then took the average soil-moisture value for the current drought and compared it with sequential（连续的） 19-year averages with the previous four, one of them 【6】(last) nearly a century. This showed that the region is already drier than it was during the first three of the previous megadroughts, and is equivalent to the event of 1575-1603.

In a world 【7】 human actions are driving temperatures up, Dr Parker and his colleagues wondered how much people are 【8】(blame) for this state of affairs. To estimate that, they turned to climate modelling.

Climate models are able to re-run the past with and 【9】 the warming effects of human activity, offering a way to compare what actually happened with what might have done. In their simulated world in which anthropogenic（人类起源的） emissions had not increased the greenhouse-gas effect, the team found that a drought did indeed still influence the western reaches of North America during the first two decades of the 21st century. But this imaginary dry spell was considerably 【10】(severe) than the real one-ranking 11th rather than 2nd in the period under study (see chart).

【题目】Come to build robots!

Robots are fun to play with, but did you know that they are equally fun to build? Don’t worry, it’s easier than you may think. You don’t have to know lots about electronics or be a genius at engineering to have a go at creating your own robot. There are lots of simple kits (配套原件) and resources available that make it easy to build a robot in your own home, and if you don’t feel confident enough to have a go at home, there are plenty of clubs that offer courses in robot-building for young people.

◇Why to build?

“Creating a robot teaches you in great about how it is put together and how it works, “says Steve Hubbard, of Robot Fun, which hosts robotics master classes for teens in Suffolk. “As you build and test a robot, you also learn how to fix it when things go wrong, as they always do.” Building and programming a robot is a practical application of science and engineering and a great way of learning how to solve all sorts of problems. You don’t need any special skills. If you can build with Lego or draw a line, you can build and program a robot.

◇How to start?

Matthew Applegate runs the Creative Computing Club in Ipswich, Suffolk. He says, “The Lego Robots kits are amazing. You can use cardboard, glue sticks and string to make a prototype (雏形).’’ Some kits can be expensive but there are ways to build your robots using things around the house. You can build an arm with cardboard, straws and string, adding it to a low-cost kit.

Building robots is really great. It isn’t easy at first，but when you get better, you will be surprised how much you can do. Come to get your first robot kit and make it whirr into life!
