The Maryland Center for History and Culture(MCHC) is currently hosting “The Jim Henson Exhibition: Imagination Unlimited”. The exhibition spotlights Henson’s unique contributions to children’s education, including his creation of the Muppets (布偶).
Born in 1936 in Mississippi, Henson grew up in Maryland. His creative talents were evident when he was a student at high school. He loved cartooning and creating sets for school theater productions. While a freshman at university, Henson made puppets for a local TV station. The station’s producers were so impressed that they asked him to produce his own puppet show. Called Sam and Friends, the program started in 1955. Viewers loved Henson’s playful characters, including an early version of Kermit the Frog.
While at university, Henson majored in home economics. At the time, it was the only major that offered classes in sewing and textiles (纺织品).Henson not only honed his creative skills at university, but he was also good at marketing and business. “He was an entrepreneur who happened to get into puppetry, ” said Deborah Wood, MCHC’s learning manager.
In 1959, Henson married Jane Nebel, whom be had met at university. The couple established Muppets Inc. which later became the Jim Henson Company. It was there that Focus Bert, Ernie, Miss Piggy, and other Muppets were created for Sesame Street, a popular children’s television program.Generations of children around the world have grown up watching and laming from the Muppets.
Henson, who died in 1990, created not just the Muppets, but also films, TV commercials, variety shows, and more. The exhibition shows every aspect of his career. This includes some lesser-known works, including The Cube, a short experimental film that was nominated (提名) for an Academy Award.
Visitors also get a chance to appreciate Henson’s creative process and inventiveness through hands-on displays. They can even make their own Muppets. “For me, I think the really powerful message of this exhibition is the fact that it covers Henson’s whole life and his whole career, ” said Chloe Green, public programs manager at the MCHC.
1. What’s paragraph 2 mainly about
A. An interesting exhibition about Henson. B. Viewers’attitude to Henson’s works.
C. Henson’s exceptional talents in creation. D. Characters in Henson’s famous works.
2. What does the underlined word “honed” mean in paragraph 3
A. Changed. B. Improved. C. Found. D. Shared.

Concrete has served as the foundation stone of the construction industry for hundreds of years. However, the process of producing concrete is one of the most environmentally unfriendly processes in the world. In the process, not only is carbon dioxide (二氧化碳) released into the air by the energy used to heat the limestone, but the limestone itself also gives out a huge amount of the element.
Luckily, a number of start-ups throughout the world are using creative thinking to make the construction industry a whole lot more friendly for the planet.
A Canadian company called CarbonCure, has found a way to inject (注入) concrete with carbon dioxide itself. Not only does this trap the carbon dioxide into the concrete, keeping it from running away into the atmosphere, but it also creates a super strong material called calcium carbonate, which reduces the total amount of concrete that needs to be used.
California-based Brimstone, is creating carbon-negative concrete by doing away with limestone entirely and instead using silicate rock, a material that does not release carbon dioxide when heated. Instead, the process produces magnesium (镁) , which absorbs carbon dioxide, as the basis for their concrete.
Additionally, researchers at Australia’s RMIT University have recently released a study showing that adding coffee grounds instead of sand to concrete could make it much stronger, reducing both the amount of sand used, as well as the amount of concrete that would need to be used in the final product.
The biggest barrier at this point is convincing members of the industry that the new types of concrete are safe to be used, according to Stacy Smedley, director at a nonprofit focused on decarbonizing construction.
Hopefully these new solutions to the environmental problems of concrete will soon be widely adopted. Given the significant part the construction industry has in releasing carbon dioxide into the atmosphere great improvements can be made when more environmentally-friendly materials are used.
5. What is the environmental issue associated with traditional concrete production
A. The high demand for energy. B. The processing of waste materials.
C. The mass release of carbon dioxide. D. The use of non-renewable resources.
6. How does CarbonCure deal with the environmental impact of concrete production
A. By using silicate rock as the basis. B. By putting carbon dioxide into concrete.
C. By replacing sand with coffee grounds. D. By absorbing carbon dioxide with magnesium.
7. According to Smedley, what is the major challenge facing these solutions
A. Difficulty in making profits. B. Convincing the public of the convenience.
C. Lack of funding for research. D. Removing the industry members’ safety concerns.
8. What is the author’s purpose in writing the text
A. To promote an alternative to concrete. B. To advocate environmental protection.
C. To introduce new ways to produce concrete. D. To emphasize the significance of creativity.

2. when 句意:当然,有时我们需要长途旅行。先行词为times,关系词在定语从句中充当时间状语。
3. who 句意:买了房子或搬家的人就是开派对的人。先行词person指人,故用who引导定语从句,who在从句中作主语。

6. why 考查定语从句。分析句子可知,空格处指代先行词the reason,并在定语从句中作原因状语,故用表原因的关系副词why来引导该定语从句。
7. who/that 考查限制性定语从句。句意:慈母手中线,游子身上衣。空格处在此引导限制性定语从句,先行词是son,指人,关系词在从句中作主语,故用who或that。
8. as 考查定语从句。句意:从他的旅行日记中我们都知道,他给我们描述了一个如此美丽的地方。当先行词前有as,such,the same等词语修饰时,定语从句由as引导。
9. who/that 考查定语从句。本句的关系代词引导定语从句并在从句中作主语,指人,故应该用关系代词who或that。
