Unit 3 Under the seaA（2017·东北三省四市教研联合体模拟)Jack was born without eyes.He was very lucky as he grew up having other kittens （young cats)to socialize with,and was used to people from the moment he was born.However,when it came time to find the kittens homes,no one knew where Jack would end up。

That's when I got an e。

mail from my friend.All she asked was “Do you still want one of the kittens？There's one here with no eyes and no one would like to take him.” Without thinking，I told her that I did want the kitten。

课时跟踪检测（一）Warming Up & Reading — Pre-reading阅读理解AEven after centuries of exploration, the ocean still holds its mysteries. Although we know more today about the world's oceans and creatures living in them than ever before, every once in a while the sea brings up something so strange, so unexpected, that makes the world wonder what it could be.Such was the case when the currents (水流) of the Mediterranean Ocean recently washed a 13­foot­long, smelly body onto the shores of the village of Villaricos in Andalusia, Spain. An early report in the Spanish publication Lavante described the strange, horned (带角的) body as what might seem like a big fish, but it was already in pieces. Locals joked that it was some kind of Loch Ness Monster.The media jumped right on the creature, of course. Some sites called it a horned sea monster. The popular newspaper Boing Boing called it a dragon. Some people guessed that it might be an oarfish, which is actually a rarely seen kind of big fish that can grow up to 55 feet long.But now the experts have weighed in and we're sorry to report that it's not a dragon, a Loch Ness Monster, or even an oarfish.“That is actually a shark skeleton (骨架)，” Professor Grubbs from Florida State University told NBC News.“The parts toward the back were confusing me, but those are the lower caudal fin (尾鳍) supports. The ‘horns’ are the scapulocoracoids which support the pectoral fins (胸鳍)．” Scapulocoracoids are backbones common to many animals.So there we go, another mystery solved. Well，the ancient maps that once described areas of the ocean as places of dragons have yet to be proven true. But it's good to know that the ocean still has a few surprises for us, even in cases where they're just dead, smelly bodies.语篇解读：本文是说明文。

O n the Twentieth Century.2、The Boy Made it!One Sunday, Nicholas, a teenager, went skiing at Sugarloaf Mountain in Maine. In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area. Unable to see far, he accidentally turned off the path. Before he knew it, Nicholas was lost, all alone! He didn’t have food, water, a phone, or other supplies. He was getting colder by the minute.Nicholas had no idea where he was. He tried not to panic. He thought about all of the survival shows he had watched on TV. It was time to put the tips he had learned to use.He decided to stop skiing. There was a better chance of someone finding him if he stayed put. The first thing he did was to find shelter from the freezing wind and snow. If he didn’t, his body temperature would get very low, which could quickly kill him.Using his skis, Nicholas built a snow cave. He gathered a huge mass of snow and dug out a hole in the middle. Then he piled branches on top of himself, like a blanket, to stay as warm as he could.By that evening, Nicholas was really hungry. He ate snow and drank water from a nearby stream so that his body wouldn’t lose too much water. Not knowing h ow much longer he could last, Nicholas did the only thing he could—he huddled(蜷缩) in his cave and slept.The next day, Nicholas went out to look for help, but he couldn’t find anyone. He followed his tracks and returned to the snow cave, because without shelter, he could die that night. On Tuesday, Nicholas went out again to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow, Nicholas was saved.Nicholas might not have survived this snowstorm had it not been for TV. He had often watched Grylls’ survival show Man vs. Wild. That's where he learned the tips that saved his life. In each episode(—期节目) of Man vs. Wild. Grylls is abandoned in a wild area and has to find his way out.When Grylls heard about Nicholas' amazing deeds, he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive.1.What happened to Nicholas one Sunday afternoon?A.He got lost.B.He broke his skis.C.He hurt his eyes.D.He caught a cold.2.How did Nicholas keep himself warm?A.He found a shelter.B.He lighted some branches.C.He kept on skiingD.He built a snow cave.3.On Tuesday, Nicholas _____.A.returned to his shelter safelyB.was saved by a searcherC.got stuck in the snowD.stayed where he was4.Nicholas left Grylls a very deep impression because he _____.A.did the right things in the dangerous situationB.watched Grylls’ TV program regularlyC.created some tips for survivalD.was very hardworking3、Daniel Anderson, a famous psychologist, believes it’s important to distinguish television’s influences on children from those of the family. We tend to blame TV, he says, for problems it doesn’t really cause, overlooking our own roles in shaping(塑造) children’s minds.One traditional belief about television is that it reduces a child’s ability to think and to understand the world. While watching TV, children do not merely absorb words and images (影像). Instead, they learn both explicit(明确的) and hidden meanings from what they see. Actually, children learn early the psychology of characters in TV shows. Furthermore, as many teachers agree, children understand far more when parents watch TV with them, explaining new words and ideas. Yet, most parents use an educational program as a chance to park their kids in front of the set and do something in another room.Another argument against television is that it replaces reading as a form of entertainment. But according to Anderson, the amount of time spent watching television is not related to reading ability. TV doesn’t take the place of reading for most children; it takes the place of similar sorts of recreation, such as listening to the radio and playing sports. Things like parents’ educational backg round have a stronger influence on a child’s reading. “A child’s reading ability is best predicted by how much a parent reads.” Anderson says.Traditional wisdom also has it that heavy televisionwatching lowers IQ (智商) scores and affects school performance. But here, too, Anderson notes that no studies have proved it. In fact, research suggests that it’s the other way around. “If you’re smart young, you’ll watch less TV when you’re older,” Anderson says. Yet, people of lower IQ tend to be lifelong television viewers.For years researchers have attempted to show that television is dangerous to children. However, by showing that television promotes none of the dangerous effects as conventionally believed, Anderson suggests that television cannot be condemned(受谴责) without considering other influences.1.By watching TV, children learn _________.A.images through wordsB.more than explicit meaningsC.more about images than wordsD.little about people’s psychology2.Which of the following is most related to children’s reading ability?A.RadiolisteningB.TelevisionwatchingC.Parents’ reading listD.Parents’ educational background3.Anderson believed that _________.A.the more a child watches TV, the smarter he isB.the younger a child is, the more he watches TVC.the smarter a child is, the less likely he gets addicted to TVD.the less a child watches TV, the better he performs at school4.What is the main purpose of the passage?A.To advise on the educational use of TV.B.To describe TV’s harmful effects on children.C.To explain traditional views on TV influences.D.To present Anderson’s unconventional ideas.4、Daniel Anderson, a famous psychologist, believes it’s important to distinguish television’s influences on children from those of the family.

课时规范训练(三十三)Ⅰ.阅读理解A（2017·四川成都诊断)From sleeping standing up to shutting down half of their brain,animals have some strange sleeping habits。

Now some of these unusual habits，from napping giraffes to birds that sleep while flying, have been shown in a chart。

This chart shows that little brown bats are very lethargic,_sleeping for around 19。

5 hours per day。

This long period of sleep is thought to be a way of conserving energy and it means brown bats only hunt for a few hours each night when their insect food is available。

In contrast，giraffes can go weeks without sleep because these large and slow­moving animals are constantly easy to the attac ks from predators.However，other animals are experts at multitasking and can swim or fly while sleeping. For example, dolphins and whales sleep while keeping half of their brain alert （警觉），so they don’t drown, with dolphins typically napping for around 10 hours a day.The method is known as “logging” and it has been observed in bottlenose dolphins，which keephalf of their brain at a low level of alertness。

No one drinks diet soda for thetaste.People drink diet soda in the hope that it will help them lose weight orat least keep them from gaining it. Yet it seems to have exactly the oppositeeffect, according to a new study.Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet soda.”What we saw was that the more diet sodas a person drank, the more weight they were likely to gain，”said Sharon Fowler.The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly 10 years.While the findings are surprising, they also offer some explanations.Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet soda, they don't lose weight at all.“We weren't seeing weight loss necessarily, and that was confusing to us，” said Rogers.So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people think they can eat more if they drink diet soda, and so over-compensate for the missing calories.A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice.“Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky，” said Helen P．Hazuda, professor at the University of Texas's school of medicine. “They may be free of calories, b ut not of consequences.”1．People drink diet soda to ________.A．enjoy its tasteB．stay in fashionC．achieve weight lossD．gain more energy2．The new study suggests that drinking diet soda ________.A．causes people to become heavierB．helps people to be healthierC．makes people much thinnerD．offers people more calories3．We can learn from the passage that ________.A．regular soda makes people lose more weightB．diet soda drinkers tend to eat more foodC．diet soda does help reduce caloriesD．most blood diseases come from diet soda4．The underlined word “They” in the last paragraph probably refers to ________.A．sweetenersB．diet sodas and artificial sweetenersC．sodasD．diet soda drinkers and sweetener takersⅢ.书面表达(2014·江南十校高三联考)最近，《二十一世纪英文报》开辟了一个中学生英语习作征文栏目，每月一个主题。
