When researchers made their first clone of an animal, Dolly, the sheep, in 1997, one doctor said, “The genie is out of the bottle. ”But then he tried to actually create the “genie” by making a human clone.
Dr. Panayiotis Zavos told the public on October 5 that he could create the first cloned human before the end of the year. He is an expert on human copying and raising from the University of Kentucky in the United States.
His workers have been stopped from carrying out research in most European Union countries, but Zavos said that fact was not slowing progress.
“It is going well enough, so we may try the first production of cloned embryos in the very near future. That is, three or four months from now,” Cypriot-born Zavos said. He moved to the United States over 30 years ago.
Human cloning could, in effect, create a copy of another living or dead person.
But Zavos insisted there was nothing harmful in the project. As an expert on human reproduction, he said he is only interested in helping couples who cannot naturally have babies to have a child. “We are not interested in cloning people like Bin Laden, Michael Jackson or Michael Jordan, ”the doctor added.
“We are only interested in helping a father who does not have the ability to have a biological child of his own. ”
Zavos said thousands of childless people from all over the world are helping in their research. He would not say where the research is under way. but indicated that it was in more than one country.

necessarily better.
"Until now most of the thinking has suggested that to be a good competitor in the forest,
you have to be a big plant," says Queen's Biology professor Lonnie Aarssen. "But our research
shows it's virtually the other way around."
Previous studies showed that larger plant species monopolize(垄断) sunlight, water and
Other resources, limiting the number of smaller plant species that can exist around them. But
the research has proved that this is not generally the case in natural vegetation.
In the Queen's project, PhD student Laura Keating targeted the largest "host plants" of 16
woody plant species growing in the Okanogan Valley, British Columbia. The research team
calculated the number and variety of plants that neighbored each large host plant. They then
randomly selected plots without host plants and calculated the plant species there as well. The
research showed that the massive trees have no effect on the number of species with which they
coexist.
Smaller plants have many advantages over their overbearing neighbors, Professor Aarssen
notes. Larger species generate physical space niches(生态位)under their shelters where smaller
species grow well. Smaller plants are much more effective than large trees at using available
resources. They also produce seeds at a much younger age and higher rate than their bigger
counterparts, and settle down much more quickly-thus competing with the newly-born plants
of larger species.
B. In the plant world, the bigger is better than the smaller one.
C. To be a good competitor in the forest, you have to be a small plant.
D. Queen's University's students made a new research.
B. larger plant species limit their smaller neighbors' growth
C. small plant species have their own advantages
D. large and small plant species can never coexist.
B. surround together
C. evolve together
D. live together
a. Randomly selected plots without host plants and-calculated the plant species.
b. Calculated the number and variety of plants that neighbored each large host plant.
c. Selected the largest individuals or "host plants" of 16 woody plant species.
B. c, b, a
C. b, c, a
D. a, c, b
B. Smaller plants can limit the number of plant species around them.
C. Smaller plants produce seeds at a higher rate than their bigger counterparts.
D. Larger trees are more effective than small plants at using available resources.
