They migrate to find food, seek a partner, or in search of warmer weather. One of the most wonderful migrations in nature is that of the North American monarch butterfly. 许多动物都会在每年的特定时间从一个地方迁移到另一个地方。这种一年一度的行为叫做“迁徙”。它们为了觅食、寻找伴侣或温暖的环境而迁徙。自然界中最壮观的迁徙之一是北美洲黑脉金斑蝶的迁徙。 1) move from one place to another:从一个地方迁徙到另一个地方 2) certain:adj.特定的 3) annual:adj.一年一度的 annual event一年一度的活动 annually adv.一年一度地，每年地 【书面表达】This is an event held annually in our school, whose theme is mainly about "cultural China" this year.

Somehow they manage to travel around 4,000 kilometres south and find their way to California or Mexico. However, until recently no one knew how（宾语从句） they did this. 每年秋天，数百万这种翅膀橙黑相间的美丽昆虫都会开始漫长而艰辛的旅程。它们总是设法完成大约4000公里的南行之旅，成功到达加利福尼亚或墨西哥。然而，直到最近人们才明白它们是如何做到的。 8) insect:n.昆虫 9) wing:n.翅膀 10) somehow:adv.不知怎么地；以某种方式 11) manage to do:设法做成某事 A team of scientists led（后置定语） by Professor Eli Shlizerman at the University of Washington has now found the answer. They have found out that（宾语从句） the monarch is able to tell the time of day. It uses its eyes to measure the position of the sun. These two pieces of information — the time of day and the point where（定语从句） the sun is in the sky — allow the butterfly to determine the way to go. Eventually, it manages to reach the places where(定语从句) it will spend the winter. 一支由伊莱·史莱泽曼教授领导的来自华盛顿大学的科学家团队现已找到了答案。他们发现，黑脉金斑蝶可以判断时间，并能用眼睛来测量太阳的位置。这两条信息——一天中的时间和太阳在天空中的位置——让黑脉金斑蝶判定前进方向，最终成功抵达过冬的地点。 12) a team of:一支团队 13) find out:发现；查明 14) be able to do:能够做某事 15) tell the time of day:判断时间 tell v.告诉；讲述；确切地判断；区分，辨别 tell sb. sth. tell stories 讲故事 tell the difference between A and B辨别A 和B tell...from...区分，辨别（tell right from wrong辨别是非） 16) measure:v.量，测量;（指尺寸、长短、数量等）度量为 n.尺寸；措施 Eg:The pond measures about 2 metres across.这个池塘宽约2米。 take measures/steps/action to do采取措施做某事 【书面表达】It is high time that we should take a series of strict measures to protect the environment. 【练习1】The bed________ 1.8metres long and it’s too short for the young man.

In many of the places where（定从） the butterfly can be found, people are destroying the natural environment. They cut down trees and use chemicals that（定从） kill the plants that（定从） monarch caterpillars eat. 黑脉金斑蝶这一惊人能力的奥秘被揭晓时，这一生物正处于水深火热的生存状态中。其数量在近几年内减少了百分之九十之多。可悲的是，人类活动是黑脉金斑蝶数量下降的主要原因。在黑脉金斑蝶生存的许多地方，人们正破坏着那里的自然环境。他们砍伐树木，他们所用的化学制剂杀死了黑脉金斑蝶幼虫食用的植物。 22） the solution to:...的解决办法 the key to...的关键 23） mystery n.难以理解的事物，谜 24） be in serious trouble：有大麻烦 25） population:n.人口；种群 26） crash:v&n..暴跌，破产；撞车，坠毁；猛撞；（计算机）瘫痪 27） in/over/during the last/past few years现在完成时时间状语 【真题再现】（天津2022.03.13）In the past ten years, one percent of our company's profits ______given to local charities. （分数百分数作主语时单复数看of后的名词） A. has been B. have been C. was D. were 28） the number of:...的数量（做主语时为单数，谓语动词用单数） a number of:许多，大量（做主语时为复数，谓语动词用原形） 【真题再现】（天津2020.7.9）The number of medical schools reached 18 in the early 1990s and ______ around that level ever since.

If（条件状语从句）this works, there may come a time when （定从）the number of monarch butterflies increases once again. The more we know about this lovely creature, the greater the chance it will survive and keep its place in the natural world for a long time to come. 不过，对黑脉金斑蝶行为的研究也使得人们对这种生物有了更多的认识。人们已经在共同努力，记录它的迁徙，并确保它有足够的食物。如果这些努力产生效果，黑脉金斑蝶的数量在未来有可能会再次回升。我们对这个可爱的生物了解越多，它们在自然界中得以长久生存并保持其地位的可能性就越大。 33） lead to:导致；通向 34） awareness:n.意识 develop/raise/increase one's awareness of... 培养/提高/增强某人对……的意识 【书面表达】Our school is expected to launch a series of activities to raise students’ awareness of protecting the environment. 35） creature:n.生物 36） record:v.记录；录制 n.记录，记载；（尤指体育运动中的）最佳纪录；唱片 37） make sure:确保 38） feed on:以...为食 39） work：起作用,奏效 40） once again:再一次 41） the+比较级，the+比较级：越...就越... 42） chance:n.机会；可能性 43） survive：v.活下来，幸存 44） keep one’s place：守住自己的位置 学科网（北京）股份有限公司 $$
