1、阅读下列短文,从每题所给的A、B、C、D四个选项中,选出最佳选项。Have you ever looked toward the sky on a fall day and witnessed a group of migrating birds? If so, you probably noted the V-shaped formation of the birds or the birds flying in a ball-like formation. Why do birds fly this way? Many theories have been developed to exp
2、lain the formation patterns of different types of birds. One theory is that birds fly in certain formations to take advantage of the laws of nature. The birds know that flying in a V-shaped pattern will save energy. Like the lead cyclist in a race who decreases wind force for the cyclists who follow
3、, the lead bird cuts wind force for the birds that follow. This decrease in wind force means that the birds use up to 70 percent less energy during their flight. When the lead bird becomes tired, a more rested bird takes over that position. But saving energy is important for more than one reason. So
4、metimes food is short during migration flights. Keeping energy enables the birds to fly longer distances between meals. When food is sighted, the birds guide one another in a different way. When a bird identifies a familiar feeding area, it might turn around in order to signal the group to change di
5、rection. Then, this bird becomes the new leader. It helps guarantee that other birds will know exactly where it is going. Then the whole group makes a change in direction, gently streaming from the sky down to the ground. This formation is like an arrow pointing to the location of food. Scientists h
6、ave also studied the birds that sometimes fly in a ball-like formation. Researchers believe that the birds come together if a predator(天敌) is spotted. The predator may then become impatient waiting for a single bird to fly away from the group. The birds will often dip and dive as a group, frustratin
7、g even the most persistent enemy. Scientists report that this is a very effective method of defense against an attack. The birds care for their fellow fliers through teamwork. As transportation expert Henry Ford once said, “If everyone is moving forward together, then success takes care of itself.”
8、When it comes to teamwork, these feathered fliers are a soaring success!1. According to the passage, we can learn that birds _. A. move faster than cyclists B. prefer to fly in a V formationC. are smarter than other animalsD. play different roles in a formation 2. When food is sighted, _.A. the grou
9、p follows the discoverer B. the lead bird decides what to doC. the discoverer leaves the group D. the whole group forms a stream3. To protect themselves from attack, birds will _ .A. break into groupsB. come close together C. change directionsD. fly up and down4. Which is the best title for the pass
10、age?A. A Birds-Eye View of Teamwork.B. Success Takes Care of Itself. C. The Strongest Will Survive.D. A Science Behind Flying.【参考答案】14、DAB A【2022高考英语湖北省汉阳市联考试题】C.400-year-old plants from the Little Ice Age were brought back to life, which could help us understand how the Earth will deal with climate
11、 change.Moss(藓类植物) found buried beneath the Teardrop glacier(冰川) on Ellesmere Island in Canada has been brought back to life. Findings suggest that these plants could help repopulate regions exposed by melting ice caps. Plants that were buried beneath thick ice in Canada more than 400 years ago and
12、were thought to have frozen to death have been brought back to life by Canadian scientists.Samples of the moss plant, covered by the glacier during the Little Ice Age of 1550 to 1850 AD, were replanted in a lab at the University of Alberta and grew new stems(茎). Researchers now think these findings
13、can give indication as to how regions can recover as the ice covering them melts.Biologist Dr. Catherine La Farge and her team at the University of Alberta were exploring the region around the Teardrop glacier on Ellesmere Island. Ice on Ellesmere Island region has been melting at around four meters
14、 each year for the past nine years. This means that many areas of land that were previously covered by ice have since been exposed. Many ecosystems that were thought to have been destroyed during the Little Ice Age between 1550 and 1850 AD can now be studied, including many species that have never b
15、een studied before.While examining an exposed area of land, La Farge and her team discovered a small area of moss called Aulacomnium turgidum. It is a type of bryophyte(苔藓类植物) plant that mainly grows across Canada, the US and the Highlands of Scotland.Dr La Farge noticed that the moss had small patc
16、hes of green stems, suggesting it is either growing again or can be encouraged to repopulate. Dr La Farge told the BBC, “When we looked at the samples in detail and brought them to the lab, I could see some of the stems actually had new growth of green branches, suggesting that these plants are grow
17、ing again, and that blew my mind. When we think of thick areas of ice covering the landscape, weve always thought that plants have to come from refugia(濒绝生物疼惜区), never considering that land plants come from underneath a glacier. Its a whole world of whats coming out from underneath the glacier that
18、really needs to be studied. The ice is disappearing pretty fast. We really have not examined all the biological systems that exist in the world; we dont know it all.”Dr La Farge took samples of the moss and, using carbon-dating techniques, discovered that the plants date back to the Little Ice Age.
19、Dr La Farges team took the samples, planted them in dishes full of nutrient-rich potting soil and fed them with water.The samples were from four separate species including Aulacomnium turgidum, Distichium capillaceum, Encalypta procera and Syntrichia ruralis. The moss plants found by Dr La Farge are
20、 types of bryophytes. Bryophytes can survive long winters and regrow when the weather gets warmer.However, Dr La Farge was surprised that the plants buried under ice have survived into the twenty-first century. Her findings appear in proceedings(论文集)of the National Academy of Sciences.59. Dr La Farg
21、es research is of great importance to _.A. knowing what the plants during the Little Ice Age were likeB. understanding how ecosystems recover from glaciers.C. regrowing many species that have been destroyed before.D. figuring out the effects of melting ice caps on moss.60. The underlined part “blew
22、my mind” in Paragraph 6 can best be replaced by “_”.A. surprised me B. greatly frightened me C. put my doubt out of my mind D. was exactly what I had in my mind61.
