All the 6,000 medals for the 2008 Olympic Games have arrived in the capital from the Shanhai Mint,ready for their debut on August 8.For the,first time in Olympic history,the medals for the Beijing Games mix metal and jade. The technology of inlaying jade into metal can date back to the Han Dynasty almost 2,000 years ago.It is not easy to bond jade perfectly with metal.The key to the process lies in the inner layer of the metal and the groove of the jade ring.A seal ring is put between the inner layer and the groove to join the metal and jade together. Jade rings used for casting Olympic medals have been subjected to strict quality controls,and those not up to the standard have been thrown away. To make use of those jade rings that do meet the quality criteria,metal medals were produced to fit the jade tings,and more than ten different sizes of seal rings were designed. To avoiding any loosening of the jade rings due to aging of the seals,glue has been used in casting the;Olympic medals,which is a painstaking manual process. Experts from the International Olympic Committee(IOC)were concerned about the risk of fragility when the jade ring design was proposed.The IOC required that jade rings should be strong enough to withstand a 2-meter drop test.The Shanghai Mint raised that standard to 3- meters.Medals call survive a 3-meter drop test with only minor cracks on the jade rings. Which of the following is TRUEaccording to the passage? A) The medals for 2008 Olympic Games are the first of this kind in history B) The medals for the 2008 Olympic Games must be more valuable than those for other Olympic Games. C) It was quite a few years ago that Shanghai Mint began to produce medals for the 2008 Olympic Games can compare with any medals for other Olympic Games.

Q: Butterfly gardens can be grown throughout the United States.There is a wide variety of both butterflyattracting (nectar) plants and host plants covering climate zones throughout the country.Butterfly gardens can range in size from a few containers placed in a sunny spot to several acres. Nectarproducing plants will attract butterflies to your garden.In order to support a full butterfly life cycle,host plants (for laying eggs and used as a caterpillar food source) must also be present. Throughout the country,the general requirements for butterfly gardening are the same:full sun,nectar source plants,larval host plants,a pesticidefree environment,and knowledge of the local butterfly species.Many butterflyattracting plants are natives and require little attention,as they are naturally adapted to the region in which they live. Butterfly gardens are best planted in spring with younger plants or in fall with mature plants that will become dormant quickly and reemerge in spring.It is best not to plant in the heat of summer or the cold of winter. One of the most common mistakes in butterfly gardening is planting only one nectar source.Adult butterflies have a very short lifespan.Planting a variety of nectar sources will encourage more butterflies to visit the garden.Planting an adequate supply of host plants gives butterflies a place to lay their eggs,which will successfully hatch and result in butterflies that will continue to visit the garden. Butterflies typically lay their eggs in late spring and hatch 3-6 days after they are laid.It takes 3-4 weeks for a caterpillar to pupate and 9-14 days to emerge as an adult. Good resources for learning more about butterfly gardening include zoos,botanical gardens,butterfly houses,garden centers and nurseries,libraries and the Internet.There are many good websites dedicated to butterflies and butterfly gardening. Native butterflyattracting plants are better because _ . A) they smell better to butterflies B) they can adapt to the local region C) they can grow faster and taller D) they can be planted in a container
