到乌蒙山区的昭通;从甘肃中部的定西，到内蒙古边陲的阿尔山，看真贫、知真贫，真扶贫、扶真贫，成为“花的精力最多”的事;“扶贫先扶志”“扶贫必扶智”“实施精准扶贫”Unit 2 Robots . 阅读理解Entering Space, astronauts can give us a fascinating account of a shuttle flight, describing the pressure of a countdown and launch, the complexities of living the days in the strange weightless environment, the challenges of working in space, the emotional effect of seeing earth from space, the drama of the meteoric landing.However, there are also plenty of things that astronauts cant do because of their weightless environment, and thats very sad. Whats more, they cant even let their sadness show, because its impossible to cry in zero gravity.Of course, astronauts can still produce tears. But crying is much more difficult in space, reported The Atlantic in January. Without gravity, tears dont flow downward out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to gothey just stick to your eyes.In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. “Tears,” he said, “dont fall off of your eye They just kind of stay there.”Besides making your vision unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But thats not the case in space. The space environment dries out astronauts eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. “My right eye is painful like crazy,” Feustel told his teammate during the walk.Since gravity doesnt work in space, astronauts need some extra help to get rid of the tears. Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait“When the tears get big enough they simply break free of the eye and float around,” astronaut Ron Parise told The Atlantic.There are lots of small thingsthings like cryingthat we are so used to on Earth. We usually take them for granted, until they become a problem in a totally different environment, like space. There, astronauts cant talk to each other directly. They also cant eat or drink in normal ways. They cant even burp（打嗝）, because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up （呕吐） everything in their stomach, according to the UK National Space Center.Thus, perhaps its only space explorers who can honestly say,“Gravity, youre the best.”1.What can we conclude from the 2nd and 3rd paragraphs?

People like that are often said to spend money “like a drunken sailor” or “like theres no tomorrow”.In the United States, people who want to start a savings account have different choices of where to put their money. 7 Credit unions are cooperatives for people who have some kind of connection. For example, the members might work for a university or a government agency. Most credit unions are non-profit organizations.Credit unions, banks and other financial institutions pay interest on savings accounts. But the interest rates are low. Certificates of deposit （存款） pay higher returns. With a certificate of deposit, a person agrees not to withdraw the money for a certain period of time. This term could be anywhere from a few months to several years. 8 People can withdraw their money early, but they have to pay a penalty（罚金）.In a number of countries, people have been saving less over the years. It is reported that in 2000, Americans had a household savings rate of 7%. 9 Many European countries have higher rates, but Americans save more than families in Japan.A.People are willing to save money for the future.B.A penny saved is a penny earned.C.Before gold, even kin
