说园（节选）陈从周① 园有静观、动观之分。所谓静观，就是园中予游者多驻足的观赏点；动观就是要有较长的游览线。小园应以静观为主，动观为辅。庭院专主静观。大园则以动观为 主，静观为辅。前者如苏州网师园，后者则苏州拙政园差可似之。人们进入网师园，宜坐宜留之建筑多，绕池一周，有槛前细数游鱼，有亭中待月迎风，而轩外花影 移墙，峰峦当窗，宛然如画，静中生趣。至于拙政园径缘池转，廓引人随，与“日午画船桥下过，衣香人影太匆匆”的瘦西湖相仿佛，妙在（ ），这是动观。动静之分，有关园林性质与园林面积大小。　　②中国园林是由建筑、山水、花木等组合而成的一个综合艺术品，富有诗情画意。叠山理水要造成“虽由人作，宛自天开”的境界。范山模水，用局部之景而非缩小(网师园水池仿虎丘白莲池，极妙)，处理原则悉符画本。山贵有脉，水贵有源，脉源贯通，全园生动。明末清初叠山家张南垣主张用平冈小陂、陵阜陂坂，就是要使园林山水接近自然，呈现水石交融的美妙境界。 ③ 中国园林的树木栽植，不仅为了绿化，且要具有画意。窗外花树一角，即折枝尺幅；山间古树三五，幽篁一丛，乃模拟枯木竹石图。重姿态，和盆栽一样，能“入 画”。拙政园的枫杨、网师园的古柏，都是一园之胜，左右大局，如果这些饶有画意的古木去了，一园景色顿减。树木品种还要有特色，如苏州留园原多白皮松，怡 园多松、梅，沧浪亭满种箬竹，各具风貌。宋人郭熙说得好：“山以水为血脉，以草为毛发，以烟云为神采。”草尚如此，何况树木呢!当然，要能做到“园以景胜，景因园异”，那真是不容易。这其中也包括花卉。　 ④园林景物有仰观、俯观之别，在处理上亦应区别对待。楼阁掩映，山石森严，曲水湾环，都存乎此理。“小红桥外小红亭，小红亭畔，高柳万蝉声。”“绿杨影 里，海棠亭畔，红杏梢头。”这些词句不但写出园景层次，有空间感和声感，同时高柳、杏梢，又都把人们视线引向仰观。文学家最敏感，我们造园者应向他们学 习。至于“一丘藏曲折，缓步百跻攀”，则又皆留心俯视所致。（ ），园林建筑物的顶，假山的脚，水口，树梢，都不能草率从事，要着意安排。山际安亭，水边留矶，是能引人仰观、俯观的方法。【注】原文有删改。

Though “nanometer”（纳米） is now a fashionable term all over the world, few people know

exactly what it is. It has become a new favorite of manufacturers and sellers in recent years.Many “high-tech” products bearing the name “nano” have entered the market,bringing more mysterious feeling to surprised consumers.

Nanometer is a very small length unit of measure,and is very small.One millimeter is 1000 micrometers,and one micrometer is 1000 nanometers.That is,one nanometer is one billionth of a meter.Nano materials are solid materials composed of particles（粒子）or crystallites（晶体） of less than 100 nanometer in size.Then,is a cup made of nano material really any different from an ordinary cup in function as far as how it works?

Are nano cups really so wonderful?A reporter went to the Institute of Nanomedicine,which is the first such institute of such a sort in the world and the only one in China,specializing in researching the investigation  of the application of nano technology into medicine.

A water molecule（分子） is composed of 2 hydrogen atoms and 1 oxygen atom.It can be changed only by special manipulation of the atoms. The material constituting the cup can have ananometer particles . But it cannot change the chemical and physical properties of the water contained in it.The water in the cup is still water. When people drink it,it will produce no special effect on human body.

Professor Ji who worked in the Instiute of Nanomedicine told the reporter, so far, the investigation of nano materials is still limited in the laboratory. No commercial micro products can be produced yet. With the present level of science and technology, the time of everyday goods made of nanometer materials is still years away.

The products labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material, which makes them more abrasion resistant（耐磨）, much easier to be cleaned, or oil resisting or moth proof（防蛀）.

Professor Ji explained that nano cup is a real up. It can also be included in the list of nano products in a certain sense. But the nano up has not changed its property and function as a cup. It is not a magical medicine for curing and health care.

72．Which of the following shows the right relationship?

A．nanometer<millimeter<micrometer<meter

B．micrometer<millimeter<nanometer<meter

C．nanometer<micrometer<millimeter<meter

D．millimeter<micrometer<nanometer<meter

73．It can be inferred from the passage that       .

A．nano materials have been put into use in daily goods

B．real nano products haven’t become available for people

C．the nano cup is very effective in curing and health care

D．real nano products are being produced by some companies

74．The underlined word “properties” in the fourth paragraph probably means        .

A．possessions      B．qualities    C．reactions   D．symbols

75．What would be the best title for the passage?

A．High-tech Products  B．Nano Cups

C．Nano Materials        D．High-teach Research
