Since their retirement, they've been spending every day fighting the advancement of the desert with the help of plant－life. Others had tried fighting the desert and failed, but they just wanted to know if they could make a difference. 课时作业(二) Relying only on their pensions, the retired couple have been slowly and steadily growing their little desert forest. They started out by planting just 50 trees, but kept doubling their efforts to the point where they now plant thousands of trees a year. Even though they mostly plant drought－resistant (抗旱的) species, they still water them at least once a day to make sure they grow better. Their small desert forest now covers over 266 hectares (公顷) and numbers tens of thousands of trees. The couple stay behind in their village, nearly 100 kilometers away from the nearest town, despite their children's efforts to get them to move with them to a more comfortable home. They've been made fun of by other villagers who believed their efforts to fight the desert were sure to fail, but they haven't let that prevent them making their efforts. They may very well fail, but at least they've given it their all. 课时作业(二) Over the last 19 years, the couple have planted over 266 hectares of desert and have no plan of stopping anytime soon. China Daily reports that Tububatu and his wife have so far planted over 70，000 trees and spent more than 1 million yuan of their savings in the process. The bad conditions have caused a lot of damage to their health. They look older than their age, and they both have been battling serious health conditions, but they refuse to abandon their battle against the desert. 篇章导读：本文是一篇记叙文。文章主要讲述了70岁的Tububatu(图布巴图)和他的妻子自退休以来，通过种树的方式对抗沙漠扩张。经过19年的不懈努力，他们取得了很大的成绩。 课时作业(二) 1．What did Tububatu and his wife do after they retired? A．They moved to the town. B．They planted trees in the desert. C．They donated their pensions. D．They worked for China Daily. 答案：B　细节理解题。根据第一段中的“Since their retirement ... the help of plant－life.(自退休以来，他们每天都在植物的帮助下与沙漠扩张作斗争。)”可知，退休后，Tububatu和他的妻子在沙漠里植树。故选B。 课时作业(二) 2．What have Tububatu and his wife achieved after the efforts of many years? A．They've grown a small forest. B．They've become healthier. C．They've inspired other villagers. D．They've developed new tree species. 答案：A　细节理解题。根据第二段最后一句“Their small desert forest ... thousands of trees.(他们的小沙漠森林现在覆盖了266公顷，有数万棵树。)”可知，经过多年的努力，Tububatu和他的妻子种出了一片小森林。故选A。 课时作业(二) 3．What does the underlined word “that” in Paragraph 3 refer to? A．A comfortable home. B．The advancement of the desert. C．The neighbors' teases. D．The unpleasant weather. 答案：C　指代判断题。根据第三段画线词前“They've ... to fail(他们被其他村民取笑，他们认为自己抗击沙漠的努力肯定会失败)”可知，画线词that指代上文提到的“They've been made fun of by other villagers”，即“邻居的取笑”。故选C。 课时作业(二) 4．Which of the following words can describe Tububatu and his wife? A．Ambitious and selfish. B．Cautious and independent. C．Humorous and outgoing. D．Determined and hard－working. 答案：D　推理判断题。根据第二段中的“Even though ... grow better.(尽管他们主要种植抗旱物种，但他们仍然每天至少给它们浇水一次，以确保它们生长得更好。)”以及第四段最后一句“They look ... against the desert.(他们看起来比实际年龄大，他们都在与严重的健康状况作斗争，但他们拒绝放弃与沙漠的斗争。)”可推知，Tububatu和他的妻子既勤劳又有决心。故选D。 课时作业(二) B Many companies are expanding their mental－health benefits (福利), but getting employees to take advantage of them can be challenging. Puget Sound Energy is on a mission to change that. 课时作业(二) Last year, 98% of its employees watched a 20－minute mental－health training video, and managers were offered a two－hour live mental－health training. The sessions included tips on how to recognize and respond to mental－health issues in themselves and others, information on what mental－health resources the company offers, and personal stories from PSE workers who had experienced mental illness. PSE is one of many companies expanding mental－health benefits and talking about mental health in the workplace in new ways. Workers are suffering from it, and companies recognize poor mental health among employees which is linked to lost productivity and higher medical expenses. Most companies already offer some free mental－health counseling (咨询) through an employee assistance plan, or EAP, to provide a certain number of counseling sessions annually for free. 课时作业(二) The problem is that EAPs are often not made full use of. While research indicates that 20% of the adult population experiences a mental illness each year, less than 8% of employees take advantage of their company's EAP, says Darren Brooks. In some cases, workers don't know their employer has an EAP because it isn't well－promoted. In other cases, workers fear there could be repercussions if their employer finds out their depression or another mental illness. Still others face long waits to book an appointment with EAP due to a national shortage of counselors. 课时作业(二) With that in mind, some companies are improving access to mental－health services. It requires training managers to recognize signs of mental－health illness and to speak about specific challenges that people experience in their daily lives. Another part of the challenge is convincing people that it is OK to use them. To make employees more comfortable asking for help, some companies are encouraging managers and workers to share their own mental－health stories. 篇章导读：本文是一篇说明文。文章介绍了很多公司关心员工的心理健康，开展了“员工救助计划”，但是因为各种原因， 这个计划并不受员工的欢迎，计划的实施遇到各种难关。 课时作业(二) 5．What was probably the aim of the sessions of PSE company? A．To get its employees devoted to their work. B．To ensure the mental health of its employees. C．To promote the sales of the company's energy. D．To train its employees for medical knowledge. 答案：B　推理判断题。根据第三段前两句可知，PSE这家公司是为了确保员工的心理健康。故选B。 课时作业(二) 6．What is the problem with EAP? A．It is not fully used by employees. B．Some employees can't afford it for lack of money. C．Employees taking it are fired because of their illness. D．Few counselors are willing to promote it to employees. 答案：A　细节理解题。根据第四段第一句“The problem is that EAPs are often not made full use of.”可知，EAP的问题是它未能被员工充分利用。故选A。 课时作业(二) 7．What does the underlined word “repercussions” mean in the fifth paragraph? A．Benefits. B．Arrangements. C．Impacts. D．Tendencies. 答案：C　词义猜测题。根据画线词所在句可知，有些工人担心，如果用这个“员工援助计划”做心理健康测试，会被老板发现自己有抑郁或其他的心理疾病，这样就会给他们带来“(不利)影响”。由此可知，画线词的意思是“影响”。故选C。 课时作业(二) 8．Which of the following is a suitable title for the text? A．Improving Mental Health Boosts Productivity B．Many People Simply Don't Want Mental Exam C．There Is a Need to Destigmatize Mental Health D．Mental－health Benefits Are Faced with Challenges 答案：D　标题判断题。通读全文可知，本文主要介绍很多公司为了关心员工的心理健康而开展的“员工援助计划”遭遇了各种挑战。由此可知，D项(心理健康福利面临挑战)最适合作为文章标题。故选D。 课时作业(二) 【持续背记】 ①However, with wildlife habitats becoming smaller, many wild animals are on the edge of extinction. 然而，随着野生动物的栖息地越来越小，许多野生动物濒临灭绝。 ②That lovely, rich fragrant smell of the forest enveloped us. 森林那种美妙、馥郁的香气笼罩了我们。 ③Every day, except for PE classes, we can expose ourselves to a variety of sports, such as running, swimming, football, basketball and so on. 每天，除了体育课，我们可以接触到各种各样的运动，比如跑步、游泳、足球、篮球等。 课时作业(二) 【持续积累】 habitat/'hæbItæt/n.
