When your pet is sick, you know it needs medication. But pets, like babies, don't know the pill you want them to take will help them.____ 1.____ Here are some tips to help get your pet to take liquid medicine.

______2.______If the answer is yes, then your easiest path is to mix it with canned food. First give your hungry pet a small amount of canned food without the medication. It's important that the pet nibbles (一点一点地吃) at the food and sees that there's nothing wrong. Next, while the pet is still hungry, mix the medication in a small amount food and present it. Repeat as necessary to get the entire dose (剂量) down.______ 3.__ If the pet decides not to finish the meal, the dose will be wasted.

If the chemist says the medication cannot be taken with food, you need a syringe (注射器) or a dropper (滴管) to get the liquid down your pet's throat. _______4.________Keep a cheerful tone in your voice so the pet doesn't sense your stress or hesitation. Position your pet where it cannot run away, perhaps having a dog sit with his back against a wall or chair ---- or a cat on your lap. ____5.______ Use your other hand to insert the syringe or dropper between the cheek and back teeth. Slowly squeeze the medication so the pet won't choke. Try to keep your pet's mouth closed for approximately 30 seconds until you see it has swallowed. If your pet is being obstinate (倔强的) , stroke (抚摸) its throat gently or blow on the face.

Be sure you end the session with praise and perhaps a treat so your pet will not associate medication with a bad experience.

You can’t see your sleeping pet’s brain waves, but its behavior can tell you when your cat might be dreaming. If you watch closely, you’ll see that as she falls asleep, her breathing becomes slow and regular with her body still. She has entered the first stage of sleep, called slow-wave sleep. After about 15 minutes you’ll notice a change in her breathing, Her eyes move under her closed lids, her paws twitch (抽动) and she flicks (轻拂) an ear. She has entered dreaming. Although she twitches and makes little grunting noises, messages from her brain to the large muscles in her legs are blocked, so she can’t run about. She is in a state of “sleep paralysis (麻痹)”.

Michel Jouvet, a French scientist, interrupted their sleep paralysis. Even though they were completely asleep, the dreaming cats began to run for balls that Jouvet couldn’t see and arched (成弓形) their backs at unseen enemies. He figured he was watching them act out their dreams! Obviously, the dreaming cats seemed to be practising important cat skills: following, catching, and fighting.

In another study, Matt Wilson recorded rats brain waves while they learned mazes (迷宫). One day, he left the brain-wave-recording machine on while the rats fell asleep. The pattern of brain waves in the sleeping rats matched the pattern from the maze so closely that Wilson could figure out exactly which part of the maze each rat was dreaming about!

Many researchers now think that in both people and animals, one purpose of dreams is to practise important skills and figure out recent learning. This may explain why so many people dream about fighting and escaping, skills that were probably important to our ancestors, and why dreaming affects our ability to learn.

Do all animals dream? From looking at the brain waves of sleeping animals, how often animals dream seems to be tied to body size. Cats dream about every 15 minutes, mice every 9 minutes, and elephants every 2 hours. And though cows and horses usually sleep standing up, they only dream when lying down.

1.What does Michel Jouvet find in his study?

A.The dreaming cats are practising their important skills.

B.The dreaming cats are in a state of body paralysis.

C.The eyes of dreaming cats move while bodies are still.

D.The dreaming cats suddenly wake up and run for the ball.

2.What can you learn from the passage?

A.Dreaming a lot can help humans learn more.

B.Learning mazes is the basic skill for cats to learn.

C.Fighting and escaping are not important skills for ancestors.

D.Rats also dream to work out their recent learning.

3.Which animal may dream most frequently?

A.Dogs. B.Rats.

C.Cows. D.Elephants.

4.How does the author develop this passage?

A.By making comparisons. B.By using figures.

C.By telling stories. D.By showing facts.

Don’t get mad the next time you catch your teenager texting when he promises to be studying. He simply may not be able to resist. A University of lowa (UI) study found teenagers are far more sensitive than adults to the immediate effect or reward of their behaviors. The findings may help explain why the initial rush of texting may be more attractive for adolescents than the long-term payoff of studying.

“For the teenager, the rewards are seductive.” says Professor Jatin Vaidya, an author of the study. “They draw adolescents. Sometimes, the rewards are a kind of motivation for them. Even when a behavior is no longer in a teenager’s best interest to continue, they will, because the effect of the reward is still there and lasts much longer in adolescents than in adults.”

For parents, that means limiting distractions so teenagers can make better choices. Take the homework and social media dilemma: At 9 p.m., shut off everything except a computer that has no access to Facebook or Twitter, the researchers advise. “I’m not saying they shouldn’t be allowed access to technology,” Vaidya says “But some help in resetting their concentration is necessary for them so they can develop those impulse-control skills.”

In their study, Vaidya and co-author Shaun Vecera note researchers generally believe teenagers are impulsive(冲动的), make bad decisions, and engage in risky behavior because the frontal lobes(额叶) of their brains are not fully developed. But the UI researchers wondered whether something more fundamental was going on with adolescents to cause behaviors independent of higher-level reasoning.

“We wanted to try to understand the brain’s reward system and how it changes from childhood to adulthood," says Vaidya, who adds that the reward character in the human brain is easier than decision-making. “We’ve been trying to understand the reward process in adolescence and whether there is more to adolescent behavior than an under-developed frontal lobe,” he adds. For their study, the researchers persuaded 40 adolescents, aged 13 and 16, and 40 adults, aged 20 and 35 to participate.

In the future, researchers hope to look into the psychological and neurological(神经学上的)aspects of their results.

1.What does the passage mainly tell us?

A.Always, rewards are attractive to teenagers.

B.Sometimes, adolescents just can’t resist.

C.Resistance can be controlled well by adolescents.

D.Getting rewards is the greatest motivation for adolescents to study.

2.What does the underlined word “seductive” mean?

A.Necessary. B.Attractive.

C.Useful. D.Important.

3.Which statement agrees with Vaidya’s idea?

A.The influence of the reward is weak in adolescents.

B.Parents should help children in making decisions.

C.Children should have access to the Internet.

D.Children need help in refocusing their attention.

4.What result does teenagers’ brain underdevelopment lead to?

A.Doing things after some thought. B.Making good decisions.

C.Joining in dangerous actions. D.Escaping risky behavior.
