从根本上看,康梁维新思想的特点决定了中国的戊戌变法运动

A.能够彻底变革中国的政治制度

B.能够彻底动摇中国的封建思想

C.不能完成挽救民族危亡的任务

D.必将遭到顽固势力的强烈反对

答案

C  

解答本题,首先要明确康梁维新思想的特点是什么,康梁维新思想把西方资产阶级思想同中国传统的儒家思想相结合,宣传维新变法的道理,这明显反映出中国民族资产阶级的软弱性。因此,在它指导下的戊戌变法运动不可能完成挽救民族危亡的历史任务。

     Fujitsu, a Japanese technology company, has created a system capable of simultaneously(同时地)

charging multiple portable electronic devices such as mobile phones, digital cameras and laptop

computers without the need for cable connections.

     Electric cars users may also eventually be able to charge their vehicles wirelessly using the same

technology, said the company, which developed a sample system at Osaka Prefecture University.

Claiming to be the world's first of its kind, the technology works on the basis of the transmission of

electricity using magnetic fields between the charger and the electronic device.

     The system enables wireless charging at distances of up to several meters. With the final aim of

installing public "charging spots" on the streets in order to enable easy charging around the clock,

scientists at Fujitsu Labs are planning to commercially sell products incorporating the new wireless

charging system as early as 2012 but have not yet decided how much they would cost.

     "This technology paves the way to integrating compact wireless charging functions into mobile

phones and enabling multiple portable devices to be charged simultaneously without any restrictions

on their position relating to the charger," the company said in a statement.

     Mobile phone users in Japan can currently charge their batteries using the disposable portable

plugin batteryoperated device, available at most train stations and convenience stores. However,

phone companies warn long time use of it can damage the phones.

     The company added, "We are also looking at applying the results of this work to fields other

than portable electronics, including power transmission between circuit boards(电路板)or computer

chips,and providing mobile charging systems for electric cars."

单项选择题

About fifty years ago, plant physiologists set out to grow roots by themselves in solutions in laboratory flasks. The scientists found that the nutrition of isolated roots was quite simple. They required sugar and the usual minerals and vitamins. However, they did not require organic nitrogen compounds. These roots got along free on mineral inorganic nitrogen. Roots are capable of making their own proteins and other organic compounds. These activities by roots require energy, of course. The process of respiration uses sugar to make the high energy compound ATP, which drives the biochemical reactions. Respiration also requires oxygen. Highly active roots require a good deal of oxygen.
The study of isolated roots has provided an understanding of the relationship between shoots and roots in intact plants. The leaves of the shoots provide the roots with sugar and vitamins, and the roots provide the shoots with water and minerals. In addition, roots can provide the shoots withorganic nitrogen compounds. This comes in handy for the growth of buds in the early spring when leaves are not yet functioning. Once leaves begin photosynthesizing, they produce protein, but only mature leaves can "export" protein to the rest of the plant in the form of amino acids.

What is the main topic of the passage

A.The relationship between a plant’s roots and its shoots.

B.What can be learned by growing roots in isolation.

C.How plants can be grown without roots.

D.What elements are necessary for the growth of plants.
