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 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 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 cast 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 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 Adballahi Ould Babah, director of locust control in Mauritania.
Requests are being made for international aid, which is the only way to limit the disaster, the UN’s Food and Agriculture Organization warned.By using “dark cloud” to describe locusts in the first paragraph, the author mainly meant to______.
| A．show the size, speed and damage of the mass of locusts |
| B．suggest the high speed that locusts travel at |
| C．warn that locusts would sweep the continent severely |
| D．hint that they look like dark monster |
The story is mainly about______.
| A．West Africa’s united effort in fighting a disaster |
| B．the difficulty in controlling locusts |
| C．the great damage locusts caused to West Africa |
| D．a struggle to fight against a disaster brought by locusts in West Africa |
According to the text we learn that the locust disaster______.
| A．can be even more serious in Asia |
| B．is then out of control |
| C．has affected greatly most areas |
| D．cannot be stopped unless twice as much pesticide is provided for the affected areas |
Which of the following is WRONG？
| A．Sud-Fm offered a reward for fighting locusts so that more people would join in the effort. |
| B．Senegal is to southwest of Sudan. |
| C．The locusts can cause such damage mainly because it has no natural enemy in West Africa. |
| D．12 countries affected by locusts have untied but still lack pesticide. |
Amazon. com has received a patent(专利) right to send its products to customers by drone planes. The company is the largest US-based online seller of products by mail and other services. Now, the company has received a patent for its planned drone delivery system.
In March, federal officials allowed Amazon to test its drone delivery plan. But even with a patent and the ability of drones to make deliveries, it does not appear the company will put its new delivery system in place any time soon.
The US Patent Office published the document, which describes Amazon’s plans to use GPS to deliver products to homes and to wherever people are. The drone will use a customer’s mobile device --- usually a smartphone ---to avoid hitting people or buildings and to find a secure area to land. The company wants to deliver products within 30 minutes after people order them on its website.
However, the Federal Aviation Administration (FAA) is worried about the safety. Although it allowed Amazon to test the system, the agency said the operators must be able to see the planes. That greatly limits the delivery area.
Loretta Alkalay is a professor at the Vaughn College of Aeronautics and Technology in New York. Although Amazon is not yet offering drone delivery, Professor Alkalay says it will not be long before it does. She says there are worries that the drones will hit buildings or people, or that the products and drones will be stolen or damaged by people on purpose. But she says that is because many people believe the drones would only deliver the products to the front door of a house. “However, it is possible that homes will one day have special area on their roofs designed to receive product deliveries,” she adds.What is special about the new delivery system?
| A．It can deliver heavy products by plane. |
| B．It uses planes without human operators. |
| C．It can delivery many products at a time. |
| D．It is much safer than other delivery ways. |
The underlined word “secure” in Paragraph 3 means “__________”.
| A．safe | B．large | C．special | D．empty |
After reading the passage, we can infer that FAA__________
| A．doesn’t really like Amazon |
| B．totally support the drone delivery system |
| C．doesn’t think Amazon should get the patent |
| D．doubts about the drone delivery system |
With all the wars, fighting and sadness in the world today, it's not only necessary, but also essential to have a good sense of humor just to help us get through each and every day of our lives. Putting a smile on someone's face when you know they are feeling down in the dumps ( 处于沮丧中), as the saying goes, makes me feel good and warms my heart.
How would you feel if you could not joke around with your wife, husband, child, co-worker, neighbor, close friend, or even just someone that you are standing in line with at your corner store? I am always saying things that make others smile or laugh, even if I don't know the person I'm joking around with. My Grandma always found humor in everything she did, even if it was the hardest job anyone could imagine. This not only relieves stress in any situation, but also is common courtesy (礼貌) to speak to others that are around you.
I know of a few people that don’t have a funny bone in their bodies, as they say. Everyone around them could be rolling on the floor after hearing a great joke and they would sit there without the slightest smile on their face. They don't get the joke that makes others laugh. I am busting a gut while they just sit there, looking at me as if I were from outer space. How can people not get a really funny joke?
Laughing is essential to keep your stress levels under control. Without humor we would find ourselves with a lot of psychological problems, or on a lot of medications to keep us from going crazy. There is too much sadness in this present world. It drives people crazy. We all need to find a way to bypass the sadness and bring a little light into our lives. So, I believe our best medicine is to get together and tell some jokes and have some fun laughing together.According to the author, humor is useful in the aspect that ____________.
| A．it makes people more confident |
| B．it can pick up people' s spirits |
| C．it can help rid the cruelty in the world |
| D．it can help people get on well with others |
The phrase “busting a gut" in the third paragraph can be replaced by __________.
| A．explaining carefully | B．speaking loud |
| C．keeping silent | D．laughing hard |
In writing the passage, the author mainly intends to __________.
| A．talk about his own understanding of humor |
| B．encourage people to be humorous in daily life |
| C．introduce a practical way to get through daily life |
| D．convince people of the power of being optimistic about life |
What is the author' s attitude towards the present world?
| A．Positive. | B．Critical. |
| C．Satisfied. | D．Indifferent. |
Why should I teach my children history? That sounds like a stupid question to even ask. But, as I hear different home schooling teachers discuss history, I get the idea that there may be different reasons for teaching history. Let me briefly explain the three good reasons for studying history and two bad reasons for studying history.
The major reason I see for studying history is that we can learn from the past. I am convinced that the world would be a much better place if more people understood the successes and failures of the past and the things that made these successes and failures. However, as the unfortunately true statement goes "the one thing we seem to learn from history is that we don't seem to learn from history." Perhaps at least in teaching history, to my children I can do a small part in changing this.
The second major reason for studying history is that it is hard to understand the current political climate in the absence of an understanding of its historical context. We can not even understand why we are and where we are without history, much less (更不必说) try to figure out where we are going or how we should get where we want to be.
I teach my children history, for one more reason. I purchased a set of historical audio (录音机) tapes for our children. My seven-year-old son listened to them over and over. It was my hope that he would become inspired by the accomplishments of people like the Wright brothers to accomplish things by himself. I think that it is good that we celebrate the accomplishments of people like Martin Luther King Jr. if, in doing so, young people are called on to stand for the principles that he stood for and accomplish what he accomplished. I also think that by studying people like Adolph Hitler, people can learn to stand against the things that he stood for. In Paragraph 3, the author shows that history is useful because _______________.
| A．it makes the current political situation go smoothly |
| B．it helps us realize the importance of historical events |
| C．it helps us understand why things are the way they are |
| D．it helps people accept the present situation where they live |
Some historical figures(人物) are mentioned in the last paragraph to show ______________.
| A．people can be inspired to do good, while also learning to fight against evil |
| B．people may also learn from bad historical figures |
| C．more celebrations should be held to honor their achievements |
| D．today’s people can also achieve what they achieved |
What would be talked about in the following paragraph?
| A．How to teach history effectively. |
| B．Some negative reasons for studying history. |
| C．How to get more people to study history. |
| D．Some bad historical figures. |
The main purpose of this passage is to ____________.
| A．inspire the parents to teach their children history |
| B．show the importance of history in politics |
| C．explain the reasons why children study history |
| D．introduce the writer' s own way of teaching history |
Put your car keys away and forget about your travel pass --- it’s time to do a bit of walking.
National Walking Month is organized every May by Living Streets, an organization that campaigns for the rights and the needs of pedestrians, so the organization is previously known as the Pedestrians’ Association. The association’s aim is to make streets safe, attractive and enjoyable spaces for people to live, work, shop and play. By putting people (rather than vehicles) first, Living Streets wants to create streets and spaces where people feel happier, healthier and more sociable.
The annual campaign gives participants a great opportunity to experience the many virtues of walking. These include the physical health benefits of becoming fitter; the environmental advantages of not using vehicles; the delight of local discoveries --- seeing more of your local areas on foot; the enjoyment of walking with other people, whether family, friends or work colleagues and finally the stress relief that comes from walking --- walking can clear your head.
Walk to School Week, 18 to 22 May, is part of the month’s activities and its aim is to encourage parents to send children to school on foot, rather than take them in the car or let them use public transport. The movement was started in 1995 with only five participating schools and now two decades later, more than one million children take part.
Similarly, there is Walk to Work Week, 11 to 15 May, where grown-ups are encouraged to walk. In the morning, getting off the bus a stop early or parking a few streets away is a good way to add more steps to the daily total. And during the working day, after having lunch at the desks or in the canteen, take a walk and get some fresh air. Walk home with your workmates and chat away about everything under the sun but work!What’s the purpose of Living Streets?
| A．To let people keep away from vehicles. |
| B．To build safer walkways for pedestrians. |
| C．To help people enjoy walking in the street and enjoy life. |
| D．To make people aware of environmental pollution. |
Paragraph 3 is intended to show that walking is __________.
| A．so interesting | B．very relaxing |
| C．perfectly safe | D．highly beneficial |
What can we learn from Walk to School Week?
| A．It is organized by the government. |
| B．It is held before Walk to Work Week. |
| C．It has developed rapidly over the last 20 years. |
| D．It encourages students to walk to school alone. |
What’s the main idea of the last paragraph?
| A．An introduction to Walk to Work Week. |
| B．A nationwide health movement. |
| C．The influence of working day. |
| D．National Walking Month’s history. |
Sunday, 31 August
We’ve been in China for a month now. Dad, Mom, Harry and I moved to Tianjin on 25 August. We’re not very far from Beijing. Two days ago, we celebrated my 16th birthday. It was great celebrating in China; the only thing that was strange was the cake--here they’re not as sweet as the ones in New York. On Monday school starts—I wonder what it will be like.
Monday, 1 September
On my first day I was looking around for a locker to put my books in. However, here all the students keep all of their books at their desks--we stay in the same classroom because apparently we don’t have to go from class to class--teachers come to us!
Today we selected teacher assistants for each subject. Their duties are to collect homework, make announcements, and do other stuff for the teacher and the students. It’s kind of a big deal here! Since I am from the US, I was asked to be the English assistant. I felt so proud but quite nervous at the same time because I wasn’t sure what I had to do, but I accepted the job anyway.
Friday, 3 October
Boy, what a week! Now we have nine classes every day, including the morning class, a combination of our American schools’ “Homeroom” and “Study Hall”. I think Chinese students work too much! I have to do my homework when I get back home. I don’t even have time to watch TV or surf the Internet like before. I sometimes miss New York and my school because we didn’t have to study so much. We had more time to hang out with our classmates and neighbors; here, besides their usual classes, students are involved in weekend classes in subjects such as English, Chinese and math.
I get a lot of attention, being from another country. Everyone wants to practice English with me! A really cute girl even asked me for my phone number on my second day and sent me a text message! I’m making a lot more friends now. I just need a lot of help to improve my Chinese. Some students want to do a language exchange program with me. Nice!The passage mentions all the following points EXCEPT .
| A．physics study | B．teacher assistants |
| C．free time activities | D．language exchange program |
According to the passage, which of the following is NOT the teacher assistant’s duty?
