Ladybirds didn't have black spots on their backs at first. Then a storm broke out, and their famous guide, Caius Insectus, disappeared into the flood , and the few ladybirds who survived had to choose a new leader to guide them out of trouble. They decided that their new leader would be the first ladybird to successfully travel south to the Great Lake and return to describe it. Many young ladybirds moved off immediately into this adventure. One by one they returned and told of how beautiful the southern lake was at that time of year, with its clear waters and flowers. However, the last of the ladybirds was late in getting back. He hadn't managed to reach the lake. Everyone criticized him, and they prepared to continue their journey the next day. Following their new guide, they spent a morning walking northwards until they reached some tall thick grassland, where they stopped. There were no clear waters or flowers in front of them. The heavy rain had turned the place into a huge green puddle . Everyone understood what had happened. When the ladybirds had gone out looking for the lake, they had gone in the wrong direction. Now they could see that, except that one late ladybird, they had lied in order to get what they wanted. And so, the late little ladybird was made the Great Guide. They also decided that every time one of them was discovered lying they would paint a black spot on that ladybird's back. From then on, when a ladybird looks at another's back, it can tell whether that ladybird can be trusted. Why did the ladybirds decide to choose a new guide? A) They lost their way in the storm. B) They weren't satisfied with Caius Insectus. C) They needed someone to lead them out of danger. D) They needed someone to help prepare for the storm.

Ques: You can't resist that shirt on sale. And those cute red shoes also end up in your shopping bag. Or you buy a new computer that you can't live without. We've all bought things we wanted but really didn't need on impulse. US statistics show that in 2009 a surprising 60 percent of all-store purchases were made without thinking first. And the latest reported statistics for e-purchases say that forty percent are impulsive. So why do we do this? It feels good. This feeling comes from a chemical called dopamine , which is released when we do something we enjoy. How can we resist the temptation to spend? l Window-shop without your wallet. This way, when you see something you want, you can't buy it. If you really need the item, you can go back to the store to buy it. But it's likely you won't. l Pay in cash-don't use credit cards. They can trick you into thinking you're not spending money because the bill doesn't come until later. Using cash will make you think twice before spending. l Research the product first----then buy it. This will keep you from being talked into buying expensive hi-tech items like computers. l Make a shopping list----and stick to it. Buy only what is on the list. l Carry the exciting item around the store for 15 minutes. You will be surprised how that purple shirt loses its appeal after the initial "Wow, isn't that cool?" feeling wears off. It's hard to give up a bad habit. But if you replace it with a healthy habit, you will have more success. Consider going to the library instead of the bookstore. Explore new parks and learn about nature, or join a church or club. Exercise with friends or join a sports team. According to the passage, people's happiness in shopping lies in _ . A) the money they spend B) the goods they buy C) the success in their lives D) the physical reaction of their own
