Ⅶ.任务型阅读
In today's world of mobile phones, MP5 players and mini computers, most people have at least one time?telling tool with them. Since these small machines are so common, will people stop wearing the 500?year?old watches? According to some people, yes. A teenager says it's unnecessary to wear a watch. Many young people agree—and use their mobile phones to tell time. Louis Galie, a president, said that fewer young people wear watches today than five years ago.
However, watchmakers say that watches get popular again when people reach their 20s and 30s. By then, they want to spend money on a nice time?telling tool which doesn't just keep good time. For this reason, the watch industry has become an accessory business(配件业) in recent years.
Today's ________ offer a lot of uses that meet the need of almost any personality(个性). They can be used as compasses(指南针), calendars, and even USB drives…
People__are__always__trying__their__best__to__create__new__kinds__of__watches. A certain watchmaker business makes watches that don't even look like watches. Their popular model uses different colour lights to tell the time. Another watchmaker business, makes a “handless” watch, using a ring of circles to keep time. This watch makes people talk a lot about modern watches.
Whether a watch expresses fashion sense, creative ability or a love of sports, people want their time?telling tools to be beautiful, fashionable and practical. All in all, a watch has become more important than the time it tells.

素材一 新课导入设计
实验导入
力学小实验：听话的火柴
Take a match. Cut the match head off the wooden stick with a knife, and use Plasticine to make a new head. Then put it into a bottle of water, adjust the size and the weight of the head until the match can make vertical floating in the water. (Note: The bottle should be quite full) Cover the mouth of the bottle tightly with your thumb. (Note: No air bubble should be found between your thumb and the water) Push your thumb down, and you will see the match run to the bottom of the bottle in the water; loosen your thumb a little, and the match will go up again…
取一根木梗火柴，将火柴头用刀削掉并用橡皮泥做一个新火柴头。然后将火柴置于一瓶水中，调节橡皮泥的大小及重量，直到火柴能竖直悬浮于水中。(注意：瓶中的水要十分满)用拇指紧按住瓶口。(注意：拇指与水之间不应该有气泡)将拇指用力下压，你会看到火柴就沉入水底；减轻拇指的压力，火柴又从水底徐徐上升。
总结：这是一个简单的沉浮实验。木梗火柴是多孔的，其中吸附着一定量的空气，随着瓶口拇指作用于水上的压力的改变，火柴中吸附的空气体积也随着增大或减小，使火柴的密度减小或增大，从而在水中出现浮、沉的变化。

Why do people cry? Scientists say the body produces tears because it needs them. One kind of tears is for the eye, and the other is for the heart. They both work as cleaners. If something else like dust(灰尘) gets into your eyes, tears also come into the eyes to clean it out. If you are hurt by something, your strong feelings produce some poisonous chemicals(毒素) in your body, and at the same time, tears come out with them. If these poisonous chemicals are not cleaned out of your body as soon as possible, they will do harm to the heart sooner or later.
In the United States men have heart problems more often than women do. Doctors say heart problems have something to do with the pressures of living and working now. Perhaps men suffer more from these illnesses because they do not cry enough. They need to cry more.
In__fact,__you__can__find__many__ways__of__reducing__the__pressures__to__keep__fit. Crying is a natural and physical one.

Ⅵ.2017·广东阅读理解
People often think of the North Pole(北极) and the South Pole as similar frozen(冰冻的) wastelands. They are both places with very cold temperatures and few people live there. However, the North and South Poles are not much alike as people may imagine.
The North Pole has no land, only thick ice. Temperatures seldom go above 32°F, at which water turns into ice. Most of the time, it stays below zero. In winter temperatures are usually as low as —30°F.
Although conditions were very poor, people tried for many centuries to reach the North Pole. About 100 years ago, two men, Robert Peary and Mathew Henson, were able to get to this environment full of troubles and difficulties. They reached the North Pole on March 8th, 1909. It was really a hard trip for them.
There are few things more dangerous than crossing the Arctic(北极圈)on foot. People who stayed there may face many problems: very cold temperatures, sudden storms, and even hunger. Most of the area is uninhabited. Few people can live in such a difficult place.
People might think that with such low temperatures for most of the year, the ice would be thick and hard. However, this is not true in the Arctic. The movement of the ocean water under the ice may often cause many different changes on the surface. Sometimes the ice breaks into two opening lanes of water(水道) called “leads”. Anyone who falls into a lead can be frozen to death in a few minutes.
( )1.This passage is probably from ________.
A．a book review
B．a science book
C．a school report
D．a computer magazine
( )2.According to the passage, what happened about 100 years ago?
A．Two men succeeded in getting to the North Pole.
B．Temperatures in the North Pole went above 32°F.
C．The environment in the North Pole suddenly became worse.
D．The North Pole changed into thick ice because of the temperatures.
( )3.What's the Chinese meaning of the underlined word “uninhabited”？
A．气候恶劣的 B．充满危险的
C．困难重重的 D．无人居住的
( )4.The reason for the ice to break into two opening lanes of water is ________.
A．that the temperature suddenly drops
B．that the water under the ice is frozen
C．that the ocean water under the ice moves
D．that the surface is covered with lots of ice
( )5. What does this passage mainly talk about?
A．The thick ice in the North Pole.
B．A difficult trip to the North Pole.
C．The real situation in the North Pole.
D．The differences between the North Pole and the South Pole.

Sleep is a very important part of our lives. After a long day, we all like the feeling of a soft bed. We know how good it will feel in the morning after we get some rest. Sleep is also very important to animals. They also need sleep after they work hard.
Some animals sleep in the sea. Fish have no eyelids(眼睑), so they sleep with their eyes open! Sea otters sleep in seaweed(海草) on top of the sea. The seaweed keeps the otters from moving along. Most sharks keep swimming while they sleep. Some fish find a little hole in the coral(珊瑚) and hide so they can sleep. The clown fish turns on its side to sleep at the bottom of the sea.
Some animals sleep under the ground! When it's hot, many frogs sleep in a hole because they want to avoid the heat. Some frogs spend the whole summer in their holes. Groundhogs live in holes in the ground, so they also sleep underground. Foxes sometimes steal a groundhog's home and use it as their own home.
What about animals that live above the ground? Birds sleep in their nests or on trees. A bird's claws (爪子) close when they sleep. This helps them stay on the tree. Bats sleep upside down for twenty hours a day!
No matter what kind of animal you are, you need your sleep.

Do you know about DNA? Here is an introduction of it.
DNA is short for deoxyribonucleic acid. It contains genetic instructions. These instructions are used in the development and functioning of all known living organisms(有机体). That's to say that your DNA decides what you are like. Perhaps this is a little bit difficult for you to understand. Here is an example to explain it more clearly. Before you were born, your DNA had already decided you would have two hands and that each hand would have five fingers. Your__hands__would__help__you__hold__things__and__do__many__other__things.
However, DNA is more than that. We ________ our DNA from our father and mother. That is why we look like our parents and are not like others. Also because of different DNA, we Chinese look different from Americans. We have black hair and eyes, but many Americans have blue eyes and blond hair. Though we have discussed many things about DNA here, there is still a lot more to know about it. If you would like to know more about DNA, you can go on the Internet.

素材一 新课导入设计
1．新闻导入
South Korean scientists said they had engineered four beagles that glowed red using cloning technique. This study could help develop cures for human diseases.
The four dogs, all named “Ruppy”—a combination of the words “ruby” and “puppy”. They looked like typical beagles by daylight.
But they glowed red under ultraviolet light, and the dogs' nails and abdomens, which have thin skins, looked red even to the naked eye.
韩国科学家称，他们利用克隆技术培育出了四条发出红色荧光的比格猎犬。这一研究能够帮助人们研发治疗人类疾病的方法。
这四条小狗都被称为“Ruppy”(“ruby”和“puppy”的合成词)。在日光下，它们看起来和普通的比格猎犬没什么差别。
但在紫外线的照射下，它们会发出红光，尤其是指甲和皮肤很薄的腹部，用肉眼都能看出红色。
2．生词传递
全班分成若干组，教师分别发给每一组最后一名学生一张纸，上面写着一个本课的单词。在教师说开始后，最后一名学生用耳语把纸上的单词告诉前面的学生，这名学生再把听到的单词告诉前面的学生……这样依次进行下去。最后，每一组的第一名学生把所听到的单词写到黑板上，传得最快，最准的组获胜。
素材二 课堂活动案例
活动一
将全班学生分成几个活动小组，组内每一名同学说出一个有关DNA的句子，最后组成一篇小短文。
活动二
教师将课文中的关键词语利用多媒体进行展示，让学生造句。
素材三 新课教学方法
1．教学方法
(1)词汇教学法：教师可以通过多媒体展示家庭树，分析家庭成员关系，在grandchild的基础上温故而知新，学习grandson, granddaughter。
(2)任务教学法：教师在课堂上可提出问题“What's DNA？”“Why do the twins look the same？”
(3)合作学习法：学生分组讨论DNA，然后连成一篇小短文，让小组成员复述。
2．学习方法
定语从句的引导词只用that不用which的情况可借助以下口诀来记忆：
that, which代表物，区别听我来叙述；
先行若是不定代，that就把which踹；先行词前有序数，就用that定无误；
先行词前最高级，还用that必无疑； 句中若有there be, that应把which替；
先行主中作表语，避免重复从句里；just, the only/very/same/last，其后也要用that。
