题目内容

【题目】 Parts of Africa are covered by a dark cloud. But this is no rain cloud. It is a living cloud made of billions of locusts (蝗虫) that are traveling across the continent eating everything in their path.

And now in the battle to stop this disaster, a radio station in Senegal, West Africa, is offering listeners 50 kilograms of rice if they can catch and kill 50 kilograms of locusts. “We think this idea will get more people to take part in the war on the locusts.” said Abdoulaye Ba, from Sud-Fm, a radio station in one of Senegal's worst affected area.

This is West Africa’s biggest locust disaster in 15 years, and it is moving east, causing huge damage to crops. As they move they produce young and increase their number and will soon threaten (威胁) Sudan in the northeast of Africa. Some say it could reach Asia. Experts say the harmful effect on crops in areas already suffering from food shortage and war could cause many people to go hungry. Governments in the areas are not well equipped to fight the pest.

Although leaders of 12 countries have agreed on a plan, it is not expected to be enough. “We are now treating 6,000 hectares (公顷) per day with pesticide (杀虫剂), but we need to treat 20,000 hectares per day in order to have any hope of controlling this disaster ,”said Mohamed Abdallahi Ould Babah, director of locust control in Mauritania.

Requests are being made for international aid, which is only way to limit the disaster, the UN’s Food and Agriculture Organization warned.

【3】The locust disaster .

这是一篇说明文。这篇短文讲述的是非洲的部分地区遭受了非常严重的蝗虫灾害，造成了很大的损失。现在政府及其他国家的领袖都已经采取措施，展开行动，消灭蝗虫。电台也呼吁更多的人加入到与蝗虫的战斗中来。

【1】推理判断题。根据第一段Parts of Africa are covered by a dark cloud. But this is no rain cloud. It is a living cloud made of billions of locusts (蝗虫) that are traveling across the continent eating everything in their path.可知，非洲部分地区被乌云覆盖，但这并不是雨云，而是由数十亿只蝗虫组成的活云，它们正在穿越非洲大陆，吃掉路上的所有东西。可推知，这里是用乌云来形容蝗虫的大小、速度和危害。故选D。

【2】主旨大意题。根据第一段Parts of Africa are covered by a dark cloud. But this is no rain cloud. It is a living cloud made of billions of locusts (蝗虫) that are traveling across the continent eating everything in their path.可知，非洲部分地区被乌云覆盖，但这并不是雨云，而是由数十亿只蝗虫组成的活云，它们正在穿越非洲大陆，吃掉路上的所有东西。结合文章主要讲的是非洲西部发生的严重的蝗虫灾害，而且各方面正为消灭蝗虫而做着努力。由此可知，文章主要讲述的是一场与西非蝗虫带来的灾难作斗争的故事。故选D。

【3】细节理解题。根据第三段中“We are now treating 6,000 hectares per day with pesticide, but we need to treat 20,000 hectares per day in order to have any hope of controlling this disaster ,” said Mohamed Abdallahi Ould Babah, director of locust control in Mauritania.可知毛里塔尼亚蝗虫控制中心主任Mohamed Abdallahi Ould Babah说：“我们现在每天要处理6,000公顷的蝗虫，但是我们需要每天处理20,000公顷的蝗虫，这样才有希望控制这场灾难。”由此可知，蝗虫灾害目前失去了控制。故选B。

【4】细节理解题。根据第二段中And now in the battle to stop this disaster, a radio station in Senegal, West Africa, is offering listeners 50 kilograms of rice if they can catch and kill 50 kilograms of locusts.可知，现在，在阻止这场灾难的战斗中，西非塞内加尔的一家电台向听众提供50公斤大米，如果他们能够捕捉并杀死50公斤蝗虫的话。由此可知，A选项“苏丹南方发展联盟—调频广播电台为抗击蝗虫提供奖励，以便更多的人参与这项努力”正确；根据第三段中As they move they produce young and increase their number and will soon threaten Sudan in the northeast of Africa.可知，随着它们的迁徙，它们会繁殖后代，数量也会增加，很快就会威胁到非洲东北部的苏丹。由此可知，可知B选项“塞内加尔在苏丹的西南部”正确；根据最后一段中Although leaders of 12 countries have agreed on a plan, it is not expected to be enough.可知，尽管12个国家的领导人已经就一项计划达成一致，但预计这还不够。由此可知，D选项“受蝗虫影响的12个国家已经联合起来，但仍然缺乏杀虫剂”正确。只有C选项“蝗虫能造成这样的破坏主要是因为它们在西非没有天敌”文章没有提到，C选项错误。故选C。

练习册系列答案

The books, blogs, YouTube videos and advice columns (专栏) will tell you that if you read, exercise, stay busy, help others, and increase your intimacy (亲密) every day, then you too can be happy.

The simple truth is that no one can be happy all the time. That doesn’t mean you have to be sad, angry, or depressed the rest of the time but that you can find a middle ground called contentment. This middle ground is a good place mentally and emotionally, and spending time there is a healthy choice.

Contentment is somewhere between satisfied and peaceful. When you are in that place, the stuff of life can be going on around you, but you don’t need to allow it to bother you. And that, my friends, is a very nice way to go through life.

I find contentment in walks and in writing, and in talking with my partner and reminding each other that our life is good, despite temporary setbacks or scary moments. Because I know about myself and I can respond differently. Doing this takes away stress and will keep you from losing your state of contentment.

If there is even one thing that puts you in a state of contentment — you do it regularly and early enough each day — it will help you go through any challenges you may have to face later.

Right at this moment, things around me are still a little out of my control — such is life — but I am feeling pretty good because I actively living my purpose. I am now content, and that feeling will last the whole day through. You can do the same.

【2】When facing setbacks or sad moments, what does the author do?

A.He turns to such media as blogs.

B.He definitely communicates with partners.

C.He adjusts himself and reacts positively.

D.He sees himself unlucky and feels depressed.

【3】What is the author most likely to agree with?

A.Still water runs deep.B.Health is better than wealth.

C.Enough is as good as a feast.D.One good turn deserves another.

【4】What is the author’s purpose in writing the text?

Hearing the news the 2022 Winter Olympic Game would be held in China, I felt very excited. It struck to me how I learned skating when I was a child. At 7, I began to go crazier about skating, like all my friends. At the beginning, it was extremely tough of me to keep my balance. I always fall over on the ground, as a result of which, I thought I had no talent for skating. So I gradually lost confidence and became impatient. The more impatient I was, the more terrible I did. I was about to give up but my father came to his assistance. I restored confidence and stood up again, being encouraged by him. As I practiced skating, he always created a relaxed atmosphere and put forward some specific advice. Eventually, I made it.

【题目】 It is no secret that physical activity is necessary to a person’s well-being. Because children are continuously developing physically and emotionally, they are especially affected by the benefits of activity. Former First Lady Michelle Obama’s Let’s Move initiative reports that nearly one-third of US children are overweight or obese, and that “schools are a key setting for kids to get their 60 minutes of play with moderate activity, given the significant portion of time they spend there.”

Physical education programs in schools directly benefit students’ physical health. Regular exercise promotes muscles and bone development. In addition to participating in physical activity, students in P.E. learn the fundamentals of a healthful lifestyle, the building blocks upon which they can develop into healthy, knowledgeable adults.

Though the lack of attention on P.E. is often justified as an opportunity to spend more time in the classroom, studies show that physical activity contributes to improved academic performance. Regular activity during the school day is strongly associated with higher concentration levels. A statewide policy in North Carolina requires that children from kindergarten to eighth grade participate in 30 minutes of physical activity each day.

Activities in P.E. help children develop healthful social interactions. From a young age, children learn cooperation through group activities and form a positive sense of identity as part of a team. Such group activities are continually important as children grow older. The International Platform on Sport and Development states that sport has been used as a practical tool to engage young people in their communities through volunteering, resulting in higher levels of leadership and community engagement among young people.

The benefits of P.E. to a child’s mental health are both complex and comprehensive. Improved physical health, academics and social interactions all contribute to good mental health. Physical activity sets the stage for a good night’s sleep, provides more energy to participate in hobbies and interact with others.

【1】The first paragraph implies that .

A.children are becoming much lazier nowadays

B.some schools have forbidden physical activity

C.most parents are dissatisfied with school education

D.schools must pay more attention to physical education

【2】Physical education is ignored in a way because .

A.children dislike taking physical activityB.schools are worried about children’s safety

C.students should have more time for studyD.less sporting equipment is available to school children

【3】What is the author’s possible attitude towards the policy in North Carolina?

A.Skeptical.B.Favorable.

C.Ambiguous.D.Objective.

【4】Which is NOT a benefit of P. E. classes?

A.They assure you of a successful future.B.They keep your mind in a good state.

C.They help you focus on your studies.D.They do good to your social skills.

【题目】 With an improved economy，many travelers have been buying first or business class seats，leaving fewer for upgrades（升级）.Here are some strategies for getting a free upgrade.

1. Fly a lot.

This is the most common way to earn a free upgrade. Most airlines reserve some spaces for travelers who fly at least 5，000 miles per year. Five years ago，this meant half or more of domestic（国内的）first class travelers sat up front for free. But now，airlines are selling more high-price seats，so on popular routes it is not unusual for more than 20 travelers to compete for one or two upgrades. But on routes with fewer business class travelers，free upgrades remain more plentiful.

2. Use miles.

If you're not a frequent traveler but still have some miles to fly，you may be able to use them for an upgrade. Be careful，though，as many airlines now ask not just for miles but also a cash co-pay. One example: on flights to Europe，American Airlines charges 5，000 miles，plus $110，for a one-way upgrade from discounted economy class to business class. For most domestic upgrades，American Airlines wants 15，000 miles plus $ 75.

3. Get lucky.

Sometimes airlines overbook coach（经济舱），and a few travelers get no seats. Agents try to ensure the airline's most loyal travelers get the nod（被选中）. Agents usually have some flexibility to make sure the plane is full and takes off on time. So it's the easiest way for them to do it-they might upgrade someone else out of order.

4. Save a life.

Flight attendants don't usually upgrade passengers, even when empty seats remain. Doctors and nurses who answer an emergency call are sometimes an exception. If they comfort a passenger, flight attendants might allow them to sit in business or first class for the rest of the flight.

【1】What might be the main topic of the passage?

A. The ways to get upgraded on a plane.

B. How to get on the flight safely and on time.

C. The best ways to get free flight tickets.

D. How to save a life on a plane quickly.

【2】Who can have the chance to get a free upgrade?

A. The person who always obeys the rules on the flight.

B. The person who doesn't have to look after a patient.

C. The person who is a friend of the flight attendants.

D. The person who flies a lot and has a long flying distance.

【3】Why might medical personnel be allowed to sit in business or first class sometimes?

A. Because they would like to talk with flight attendants kindly.

B. Because they want to have a better rest after a long journey.

C. Because they need to treat a passenger who is in emergent condition.

D. Because they are tired of staying with common passengers.

【4】Where can we find the passage?

A. A life guide.B. A travel guide.

C. A shopping guide.D. A pilot guide.
