21、Nuclear power's(核能的) danger to health, safety, and even life itself can be described in one word; radiation(辐射). Nuclear radiation has a certain mystery about it, partly because it cannot be detected (探测) by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things. At very high levels, radiation can kill an animal or human being completely by killing masses of cells (细胞) in important organs (器官). But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be significant. This is the case when only a few cells are hit, and if they are killed completely. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated(放射治疗) and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents. Radiation can hurt us. We must know the truth.
【1】According to the passage, the danger of nuclear power lies in __________.
A. nuclear mystery B. radiation detection
C. radiation level D. nuclear radiation
【2】Radiation can lead to serious results even at the lowest level ________.
A. when it kills few cells
B. though the damaged cells can repair themselves
C. if it damages few cells
D. unless the damaged cells can reproduce themselves
【3】Radiation can hurt us in the way that it can _____.
A. kill large numbers of cells in main organs so as to cause death immediately
B. damage cells which may grow into cancer years later
C. affect the healthy growth of our younger generation
D. lead to all of the above results
【4】Which of the following can be best inferred from the passage?
A. The importance of protection from radiation cannot be too overemphasized (过分强调).
B. The mystery about radiation remains unsolved.
C. Cancer is mainly caused by radiation.
D. Radiation can hurt those who do not know about its danger.
22、Chinese painters painted on various materials in many formats. The most popular materials with the earliest artists were wood and bamboo but then the following were adopted: plastered walls, silk, and paper. Canvas would only be used widely from the 8th century CE. Brushes were made from animal hair, cut to a tapering end and tied to a bamboo or wood handle. Significantly, they were precisely the same instruments used by the calligrapher. The inks used were made from rubbing a dried cake of animal or vegetable matter mixed with minerals and glue against a wet stone. Each artist had to laboriously (辛苦地) make their own inks as there was no commercial production of them.
The two most popular themes of Chinese painting were portraits and landscapes. Portraits in Chinese art began in the Warring States Period and were traditionally rendered with great restraint, usually because the subject was a great scholar, monk or court official and so should, by definition, have a good moral character which should be portrayed with respect by the artist. For this reason, faces are often seemingly impassive (面无表情的) with only the merest hint of emotion or character subtly expressed. Often the character of the subject is much more clearly expressed in their attitude and relationship to other people in the picture; this is especially true of portraits of emperors and Buddhist figures.
Landscape painting had been around as long as artists had, but the genre really took off during the Tang dynasty when artists became much more concerned with humanity’s place in nature. Typically, small human figures guide the viewer through a panoramic (全景的) landscape of mountains and rivers in Tang paintings. It should be no surprise that mountains and water dominated landscape painting as the very word in Chinese for landscape translates literally as “mountain-and-water”. Trees and rocks are also featured and the whole scene is usually meant to capture a particular season of the year. Colours were limited in use, either everything in various shades of a single colour (illustrating the roots in calligraphy) or two colours combined, usually blues and greens.
【1】Which of the following is the latest material used by ancient artists?
A．Bamboo.
B．Canvas.
C．Paper.
D．Silk.
【2】Why did artists make inks themselves?
A．No one sent inks to calligraphers.
B．They wanted to make suitable inks for them.
C．No inks were sold in the markets.
D．The materials used were easy to find.
【3】Who is most likely to be the figure in the portrait according to the passage?
A．An educator.
B．A singer.
C．A cowboy.
D．A businessman.
【4】What began to rise in the Tang Dynasty?
A．Portraits.
B．Landscapes.
C．Wall paintings.
D．Calligraphy.
23、Every sentence we speak shows something about who we are as humans. Even people speaking the same language have distinct dialects. 【1】 Whether you say “soda” or “pop” may reveal what country and what region you are from. What you call the night before Halloween may tie to your religious beliefs.
【2】 Plants and animals that are given names in any language are generally those that are relevant to people speaking the language. The relevance comes from the way that the people have interacted with the animals and plants. In some cases, this has happened over centuries.
While we might think of language as having a fixed set of words and rules that we learn in school, in fact language is always evolving. New words emerge while others fall out of use. Pronunciation changes over time as does the meaning of words. 【3】
Our ability to learn language develops when we are young. Sounds heard as infants, or even in the womb, set the stage for language learning later. Baby cooing is the result of babies’ analysis of the languages spoken to them. 【4】 Children exposed to multiple languages early in life, and growing up multilingual, develop enhanced cognitive functions. These may include the ability to focus and ignore distractions.
Languages are as diverse as the communities that speak them. Each of the approximately 7, 000 world languages is a testimony to a community’s unique human experience. Yet, many languages around the world are endangered. It is possible that as many as half of the world’s languages could go silent by the end of this century. Why?【5】 But they boil down to social inequalities and disrespect for others.
A．The reasons are complex.
B．Languages change with time.
C．These are rooted in their history and culture.
D．What kind of slang you use may come from the habits of place you grew up in.
E．Language also shows the connections between us, and our natural environment.
F．Babies are practicing the pronunciation of sounds that they need for communication.
G．People also borrow words from languages other than their own to add to their own vocabulary.
24、Scientists often compare coral reefs(珊瑚礁) to underwater rainforests, yet unlike the leafy plant base of a forest, corals are animals. The soft creatures are naturally half-transparent and get their brilliant color from algae(藻类) living inside them. When corals experience stress from hot temperatures or pollution, they halt the interdependent relationship with algae, typically pushing them out and turning white. Corals are still alive when they are white, but they're at risk and many eventually die, turning dark brown.
Scientists around the world are looking for means to protect and maybe increase corals. One common option is to create more protected areas — essentially national parks in the ocean. Beyond nature preserves, some conservationists are looking to more hands-on methods. One research center in the Florida Keys is exploring a form of natural selection to keep corals remaining. The reef system in the Keys has been hit hard by climate change and pollution, which is especially tough, because corals there help support fisheries worth $ 100 million every year.
To keep the wild ecosystem alive, Erinn Muller, the center's director, and her team are harvesting samples of the corals that survived the environmental stress naturally, keeping them to make them reproduce, and then reattaching them to the reef. They have 46,000 corals on plastic frames under the sea. So far, the center has regrown over 70,000 corals from five different species on damaged reefs.
In The Bahamas, Ross Cunning, a research biologist at Chicago's Shedd Aquarium, focuses on corals with genes that could make them natural candidates for restoration projects. He published a study of two Bahamian reefs, one that survived an extreme 2015 heat wave, and one that didn't. "We think their ability to deal with these higher temperatures is built into their genes," says Cunning. There's evidence of corals evolving more quickly to resist rapidly warming climate. The big question scientists need investigate, adds Gunning, is how much more heat corals can adapt to.
【1】What does the underlined word "halt" in the first paragraph mean?
A．End.
B．Develop.
C．Strengthen.
D．Weaken.
【2】What do Muller and her team do to save corals?
A．Restore the damaged reefs.
B．Grow corals by hand underwater.
C．Create more protected areas.
D．Move corals to unpolluted areas.
【3】What do Gunning's words suggest?
A．Many corals have been genetically improved.
B．Cooling down the waters is key to rescuing corals.
C．Reasons for corals surviving heat waves are shocking.
D．The highest temperature corals can survive is unclear.
【4】Which can be a suitable title for the text?
A．Relationship between corals and algae
B．Efforts made to save corals
C．Impact of climate warming on corals
D．Survival crisis faced by coral reefs
