input: Chinese player Li Na, a two-time Grand Slam champion, announced her retirement on Sept 21 because of long-term knee injuries. Although it was a hard decision, Li said she had no regrets . "I don't feel sorry about retiring, because I've tried my best," said the 32-year-old. Becoming professional at the age of 17, Li has set many milestones for Chinese tennis. She was the first Chinese player to win a WTA title and the first to break into the top 20. Li won the 2011 French Open title and became the first Asian player to ever win a Slam. By winning this year's Australian Open, she became the first Asian player with two Slams. As excellent as her tennis abilities are, Li's sense of humor is _ too. She often jokes about life with her husband in interviews, changing them into funny comedy shows. Her speech at the Australia Open in January is just the best example. During her 15-year professional career, Li has helped the improvement of tennis in China. Earlier this month, Chinese another player Peng Shuai, 28, made the semifinals of the US Open. Last week, a new tennis match started in Li's hometown of Wuhan. "I've seen changes happening in front of my eyes, young girls picking up tennis rackets, setting goals ... and believing in themselves," Li said in an online post. Li is more than a sports superstar. As WTA chief executive Stacey Allaster said, she is "a pioneer who opened doors to tennis for hundreds of millions of people throughout China and Asia." Li said she planned to take care of my family and then to open a tennis school in China after her retirement. Her official retirement ceremony will be on Sept 30. 1. How old is Li Na?

question: The flowering plants (angiosperms), also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with about 350,000 species. Like gymnosperms, angiosperms are seed-producing plants; they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure, in other words, a fruiting plant. The term "angiosperm" comes from the Greek composite word (angeion-, "case" or "casing", and sperma, "seed") meaning "enclosed seeds", after the enclosed condition of the seeds.

Fossilized spores suggest that higher plants (embryophytes) have lived on land for at least 475 million years. Early land plants reproduced sexually with flagellated, swimming sperm, like the green algae from which they evolved. An adaptation to terrestrialization was the development of upright meiosporangia for dispersal by spores to new habitats. This feature is lacking in the descendants of their nearest algal relatives, the Charophycean green algae. A later terrestrial adaptation took place with retention of the delicate, avascular sexual stage, the gametophyte, within the tissues of the vascular sporophyte. This occurred by spore germination within sporangia rather than spore release, as in non-seed plants. A current example of how this might have happened can be seen in the precocious spore germination in Selaginella, the spike-moss. The result for the ancestors of angiosperms was enclosing them in a case, the seed. The first seed bearing plants, like the ginkgo, and conifers (such as pines and firs), did not produce flowers. The pollen grains (males) of Ginkgo and cycads produce a pair of flagellated, mobile sperm cells that "swim" down the developing pollen tube to the female and her eggs.

Question: A pub /pb/, or public house is, despite its name, a private house, but is called a public house because it is licensed to sell alcohol to the general public. It is a drinking establishment in Britain, Ireland, New Zealand, Australia, Canada, Denmark and New England. In many places, especially in villages, a pub can be the focal point of the community. The writings of Samuel Pepys describe the pub as the heart of England.

The history of pubs can be traced back to Roman taverns, through the Anglo-Saxon alehouse to the development of the modern tied house system in the 19th century.

Historically, pubs have been socially and culturally distinct from cafes, bars and German beer halls. Most pubs offer a range of beers, wines, spirits, and soft drinks and snacks. Traditionally the windows of town pubs were of smoked or frosted glass to obscure the clientele from the street but from the 1990s onwards, there has been a move towards clear glass, in keeping with brighter interiors. 1. What is a pub?
2. What is it for?
3. what does it serve?
4. Anything else?
5. Are they in America?
6. where? Provide a numbered list of answers.
