语言点详解

1．掌握不定式的被动用法

动词不定式是由“to+动词原形”构成(有时可以不带to)。动词不定式的否定形式是“not+动词不定式”(not不与助动词连用)。动词不定式又具有名词、形容词和副词的特征，因此在句子中可以作主语、宾语、表语、宾语补足语、定语和状语等句子成分。

不定式作定语只能用被动式的情况如下：

(1)为了表达需要，强调不定式动作的执行者时．须用被动式．常用by结构引导。

例：2008 Olympic Games are the first great Olympic Games to be held by Chinese 2008年奥运会是中国人首次举办的奥运盛会。

(2)不定式所修饰的名词是将要被做的事情时．不定式须用被动式。

例：The problem to be discussed at the next meeting is of great importance．

下次会议上将要讨论的这个问题至关重要。

The building to be built next yea r will be used at the office building

明年要建设的大楼将用作办公楼。

·注意点：

(1)在“There be”结构中，主语被不定式修饰(不定式作定语)时．既可用主动式，也可

用被动式．意义上无甚区别。

例：There was a lot of problems to deal with／to be dealt with.

有许多问题需要处理。

(2)在“with／without十宾语+宾语补足语”结构中，若宾语补足语是不定式，不定式表

示将要发生的动作．且句子的主语是该动作逻辑上的执行者．此时不定式须用主动式。

例：With a lot of difficult problems to settle．the newly—elected president is having a hard time．

2．threat的用法

Most people picture sharks (鲨鱼) as huge, powerful, frightening predators (食肉动物)，ready at any moment to use their sharp teeth to attack swimmers. There are a lot of 1 about sharks.

First, there are about 350 2 of sharks, and not all of them are large. They range in 3 from the dwarf shark, which can be only 6 inches (0. 5 ft. ) long and can be held in the hand, 4 the whale shark, which can be more than 55 feet long.

The second misunderstanding of shark concerns the 5 and type of its teeth, which can vary tremendously among the 6 species of sharks. A shark can have from one to seven sets of teeth at the same time, and some types of sharks can have several hundred teeth in each jaw. It is true that the cruel and predatory species do have extremely 7 teeth used to tear and cut their victim apart, many other types of sharks, however, have teeth more suitable to holding than to cutting.

8 , not all sharks are predatory animals ready to strike out at humans. In (act, only 12 of the 350 species of sharks have been known to attack humans, and a shark 9 be provoked in order to attack.

Reading

(A)

If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise—and as a result, we are growing old unnecessarily soon.

Professor Taiju Matsuzawa wanted to find out why quite healthy farmers in northern Japan appeared to be losing their ability to think and reason at a rather early age, and how the speed of getting old could be slowed down.

With a team of researchers at Tokyo National University, he set about measuring brain volumes (容量) of a thousand people of different ages with different jobs.

Computer technology helped the researchers to get most exact measurements of the volume of the front and side parts of the brain, which have something to do with intellect and feelings, and decide the human character. As we all know, the back part of the brain, which controls tasks like eating and breathing, does not contract (萎缩) with age.

Contraction of front and side parts—as cells die off -was seen in some people in their thirties, but it was stilt not found in some sixty-and seventy-year-old.

Matsuzawa concluded from his tests that there is a simple way to prevent the contraction —using the head.

The findings show that contraction of the brain begins sooner in people in the country than in the towns. Those with least possibility, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing the same work day after day in government offices are, however, as possible to have contracting brains as the farm worker, bus driver and shop assistant.

1. The team of doctors wanted to find out______.

A. at what point people grow mentally old

B. how to make people live longer

C. the size of certain people's brains

D. which people are the most clever

2. Their research findings are based on______.

A. an examination of farmers in northern Japan

B. tests given on a thousand old people

C. examining the brain volumes of different people

D. using computer technology

3. The doctors' tests show that _______.

A. our brains contract as we grow older

B. one part of the brain does not contract

C. sixty-year-old have better brains than thirty-year-old

D. some people's brains have contracted earlier than other people's

4. According to the article, ______are growing old earlier than people who live in the cities.

A. farmers

B. office clerks

C. shop assistants

D. bus drivers

5. The most possible conclusion of the passage is that______.

A. most of us should take more exercise

B. it's better to live in the town

C. the brain contracts if it is not used

D. the more one uses his brain, the sooner he becomes old

(B)

Whether the hair is long or short, it must be regularly brushed and washed. For greasy (油腻的) hair，especially if the owner lives in a town, it may be necessary to wash the head every four to five days. Those with dry hair can usually go a little longer, but this is a matter for each person to decide.

If a woman is not able to go to hairdressers very often, it is important that she choose a style she can easily manage for herself，and this nearly always means that the first cut must be very standard.

One thing should be remembered though, that is, whatever you apply to the head can have some effect upon the skin and therefore anything strong should be used with care. Or you may use milder products. As for style, this must be studied according to what the latest fashion is and also to suit the individual at different times of her life.

Young people who has spots or skin troubles on their face, should take particular care to make sure that the hair is clean and does not touch the affected piece of skin. Hair is very difficult to keep completely clean and therefore anyone running his hands through his hair and afterwards

touching his face, or letting his hair fall over his face, might spread infection (感染) from one place to another. Good hair does a lot to the effect of a face, so if you want to look nice, please start with your hair.

1. According to the text, the most basic thing to do in hair care is to______.

A. go to hairdressers very often

B. choose better and milder products for the hair

C. wash and brush the hair regularly

D. keep the hair away from the skin trouble

2. The best hair style can be achieved by______.

A. having the hair cut standard

B. following the latest fashion to suit one's age

C. not combing the hair with hand

D. not applying anything strong to the head

3. The thing you wash your hair with must be_______.

A. used with care

B. very strong

C. extremely mild

D. fashionable

4. To prevent the hair from infecting the skin, we'd better ______.

A. keep the hair completely clean

B. wash the hair very often

C. have hair cut four times a year

Words and their stories EAGER BEAVER An eager beaver is a person who is always willing to do and is excited about doing what is expected of him. Suppose, for example, that a teacher tells his students they each must solve one hundred math problems before coming to school the next day. The children complain about so much homework. But one student does not protest at all. That student is an eager beaver. He loves to do math problems, and does not mind all the homework. The expression is said to have come from the name of a hard-working animal---the beaver. Beavers are strange-looking creatures. They spend a lot of time in the water, building dams to create little lakes or ponds. They use their huge teeth and work hard to cut down trees, remove branches and put them across streams. They use their tails to pack mud on the branches to make the dams solid. Few other animals work so hard. Historians say the beaver had an important part in the settlement of North America. There were hundreds of millions of beavers when European settlers first arrived. The settlers put great value on the fur of beavers. In fact, for two

沪教版六年级数学下册全套教案+习题

六年级下册第五章有理数知识点 1、正数：大于0的数叫做正数。 2、负数：在正数前面加上负号“-”的数叫做负数。 3、0既不是正数也不是负数。 零是正数和负数的分界。 4、有理数：整数和分数统称为有理数。 有理数：正数：正整数、零、负整数 分数：正分数、负分数 5、数轴：规定了原点、正方向、单位长度的直线叫做数轴。 数轴上的点从左到右依次增大，正数大于零，零大于负数，正数大于负数。 6、相反数：绝对值相等，只有负号不同的两个数叫做互为相反数。 7、绝对值：一般地，数轴上表示数a的点与原点的距离叫做数a的绝对值。记做|a|。 由绝对值的定义可得：|a-b|表示数轴上a点到b点的距离。 一个正数的绝对值是它本身；一个负数的绝对值是它的相反数；0的绝对值是0. 8、有理数加法法则 加法交换律：有理数的加法中，两个数相加，交换加数的位置，和不变。 表达式：a+b=b+a。 加法结合律：有理数的加法中，三个数相加，先把前两个数相加或者先把后两个数相加，和不变。 表达式：（a+b）+c=a+（b+c） 9、有理数减法法则 减去一个数，等于加这个数的相反数。 表达式：a-b=a+（-b） 10、有理数乘法法则 两数相乘，同号得正，异号得负，并把绝对值相乘。 任何数同0相乘，都得0. 乘法交换律：一般地，有理数乘法中，两个数相乘，交换因数的位置，积相等。 表达式：ab=ba 乘法结合律：三个数相乘，先把前两个数相乘，或者先把后两个数相乘，积相等。 表达式：（ab）c=a（bc） 乘法分配律：一般地，一个数同两个的和相乘，等于把这个数分别同这两个数相乘，再把积相加。 表达式：a（b+c）=ab+ac 注意：几个不等于零的数相乘，积的符号由负因数的个数决定，当负因数有奇数个时，积为负；当负因数有偶数个时，积为正；几个数相乘，有因数为零，
