Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can39。t talk, but can they lie in other ways? Can they lie with their bodies and behavior? Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive.Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator（獵食動物）gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the hurt adult, leaving the baby birds safe in the nest. Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.Birds called cuckoos have found a way to have babies without doing much work. How? They don39。t make nests. Instead, they get into other birds39。 nests secretly. Then they lay their eggs and fly away. When the baby birds e out, their adoptive parents feed them. Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner39。s hand and start fighting again. Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps e running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don39。t hear them, and they don39。t need to share their food.As children, many of us learn the saying You can39。t fool Mother Nature. But maybe you can39。t trust her, either.66.

Consider putting the habit loop to use.Here39。s how it works:A habit is a 3step process. First, there39。s a cue, something that tells your brain to operate automatically. Then there39。s a routine. And finally, a reward, which helps your brain learn to desire the behavior. It39。s what you can use to createor breakhabits of your own. Here39。s how to apply it:Choose a cue, like leaving your running shoes by the door, then pick. a rewardsay, a piece of chocolate when you get home from the gym. That way, the cue and the reward bee interconnected. Finally, when you see the shoes, your brain will start longing for the reward, which will make it easier to work out day after day. The best part? In a couple of weeks, you won39。t need the chocolate at all. Your brain will e to see the workout itself as the reward. Which is the whole point, right?70. Which of the following best fits in the box with a “?” in THE HABIT LOOP?A. Pick a new
