With the development of modern science and technology, the functions of cellphones have changed greatly. 1. The only difference may be that they fit in your pocket and you pay by the minute to use them. Some of the things a cellphone can do for you will be available this year:

Surf at speed

Cellphones that let you use the Web have been around for years. So, what's new? Well , faster third-generation (3G) networks that let you surf at anywhere. 2. Possible choices are from IJG Electronics VX 8000 and Motorola V1150.Listen as you go.

3. There is no doubt that it is about to change. Sony Ericsson’s new W8001 can hold around 150 songs in its 500 MB memory. And Samsung's SPH-V5400 even comes with a l. 5 GB hard drive. Mobile phones may eventually replace miniMP3 players, especially for teens. Say cheese.

Camera cellphones are not new either but most of them have limitations: around l- megapixel (百万像素 ) . However new technology has made 2-megapixel units more common ,and 3-megapixel units are showing up soon. Some 2-megapixel models, like Sony Ericsson's K7501, offer limited zoom and focus controls. 4. Portable TV.

You say you like "watching TV"? That’s what Samsung MMA700 wants to give you. The new model lets users watch popular TV programmes~ for a fee. Other choices are Nokia's 6620, Sanyo's MM740 and NEC's N940. 5.The above are just a handful of what you ' ll see in the coming months. Further down the road, your mobile phone may play a host of other roles, such as mobile credit card, position locator and so on. So what is there that a cellphone can't do?

A. The NEC model lets you watch public TV - no fee.

B. Without a cellphone, you can do nothing in your daily life.

C. Nowadays, new cellphones are much cheaper than old ones.

D. Today's do-it-all mobiles have a lot in common with the computer.

E. This then allows a carrier to send video, music, and games to your phone.

F. Others, like LG's recent A7110, can even capture 30 minutes of full-motion video.

G. The problem with most cellphone MP3 players is that they hold only a handful of songs.

 

  Ten years ago, with only about 1, 000 pandas left in the world, China was desperately trying to clone(克隆)the animal and save the endangered species(物种). That was a move similar to what Texas A & M University researchers had been undertaking for the past five years in a project called “Noah’s Ark”(诺亚方舟).

Noah’s Ark was aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, said there would be enough of the basic building blocks to reintroduce the species in the future.

It was estimated that as many as 2, 000 species of mammals, birds reptiles would become extinct in over 100 years. The panda, native only to China, was in danger of becoming extinct in the next 25 years.

This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They were then trying to implant the embryo into a host animal.

The entire procedure could take from three to five years to complete.

“The nucleus transfer(核子移植)of one species to another is not easy, and the lack of available(capable of being used)panda eggs could be a major problem,”Kraemer believed. “They will probably have to do several hundred transfers to result in one pregnancy(having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort, ”added Kraemer, who was one of the leaders of the project at Texas A& M, the first-ever attempt at cloning a dog.

“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed. ”

At present, the project has worked. The number of the pandas has increased to more than 1, 500.

1.The aim of “Noah’s Ark” project was to    .

A. make efforts to clone the endangered pandas

B. save endangered animals from dying out

C. collect DNA of endangered animals to study

D. transfer the nucleus of one animal to another

2. According to Professor Kraemer, the major problem in cloning pandas would be the lack of    .

A. available panda eggs   B. host animals

C. qualified researchersD. enough money

3. The best title for the passage may be    .

A. China’s Success in Pandas Cloning

B. The First Cloned Panda in the World

C. Exploring the Possibility to Clone Pandas

D. China—the Native Place of Pandas Forever

4.From the passage we know that    .

A. Kraemer and his team had succeeded in cloning a dog

B. scientists tried to implant a panda’s egg into a rabbit

C. Kraemer would work with Chinese scientists in clone researches

D. about two thousand species would probably die out in a century

 

A. Airport services

B. Air transport prices

C. Transport by plane

D. Development

E. Fast growth in the US airlines

F. Beginning time

1.       

Airplanes are used to carry passengers, cargo and mail. Air transport companies run scheduled airlines and non-scheduled services over local, national, and international routes. The aircraft run by these companies change from small planes to large planes.

2..       

The first air passenger services began in 1910, when dirigibles(飞艇)began working between several German cities. The first scheduled airplane service to carry passengers began in the US in 1914. Several experimental airmail flights took place in India, Europe, and the USA before World War I, but air transport services did not become a true business until after the war.

3.      

During World WarⅡintercontinental air transport began to become well set-up. After the war the new long-distance planes with developed equipment were increasingly able to prevent storms and strong wind and make flights cheap. Jumbo Jets began working in 1970.

4.      

During the 1970s the number of home passengers on US airlines increased about 78%, and during the 1980s the number was up about 58%. In 1990 there were 41. 8 million international passengers: the number was a 75% increase over 1980.

5.       

Major airports provide all kinds of services to make travel easy and pleasant for passengers. These change from such basic services as ticket-sales counters and restaurants to luxury(豪华的)hotels, shopping centers and play areas for children.
