1、Module 5 A Lesson in a Lab一、阅读理解（-）The strength of TC Williams High School in Alexandria, Virginia is its diversity （多样性），says Shawn Lowe, a science teacher at the school. Her students are interested in doing science fair projects, but dont have enough money to pursue them.“Having equipment availabl
2、e allows every student to pursue their questions and carry out real science research, regardless of socioeconomic means, she said.Fortunately, a STEM Research Grant from the Society for Science & the Public has allowed Shawn to buy much-needed equipment. So far this year, she has supported 24 studen
3、ts as they completed projects to present at science fairsthree times the previous number of students.Without the grant, I would not have had the freedom to buy the equipment needed, n Shawn said. “The grant has directly influenced about 20 science fair projects that would otherwise not be available.
4、 It also provides opportunities this year for about 40 students, and will expand in the next few months as my students show what they are doing to elementary and middle school students, encouraging more students to carry out hands-on scientific inquiry, “ Shawn said.The STEM Research Grant also allo
5、wed Shawn to buy materials for a group of students to build a drone （无人才儿）.Without these materials, we would not have been able to build a drone, and wouldnt have had a project. The influence has been huge. With these materials, we have been able to create a machine that will be able to fly automati
6、cally （自动地）.We are proud of it, the students explained.The grant may have directly affected these young scientists while they study at TC Williams High School, but its impact in their lives wont end there. Many will go on to study STEM subjects in college, including the students who built the drone
7、and who plan on becoming engineers.1. What difficulty do the students have in doing science fair projects?A. They are short of money.B. They lack professional guidance.C. They dont get the support of the school.D. They dont have confidence after many failures.2. What does the underlined word “grant
8、in Paragraph 4 most probably mean?A. Money. B. Interest.C. Agreement. D. Equipment.3. What does the underlined word uitn refer to in Paragraph 5?A. The drone. B. The influence.C. The project. D. The grant.4. What does the last paragraph mainly talk about?A. How to become an engineer.B. How to choose
9、 a suitable university.C. The different choices of students after high school.D. The great influence of doing science projects at school.（二）AMany animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat.
10、You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend
11、 on only one of their senses, while most animals use more than one sense.Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice.
12、A kind of white butterfly w川 stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet （多 样化饮食）.The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be differen
13、t depending on the season.Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and ani
14、mal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.1. We can infer from Paragraph 1 that humans and animalsA. depend on the same sense in choosing foodB. choose food by their look and smellC. choose food in sim
15、ilar waysD. eat entirely different food2. What animal eats only one type of food?A. The white butterfly. B. The small bird.C. The bear. D. The fox.3. When will animals change their choice of food?A. The season changes.B. The food color changes.C. They move to different places.D. They are attracted b
16、y different smells.4. What can we learn from the last paragraph?A. French and British food is good.B. Food is chosen for a good reason.C. Some people have few choices of food.D. Some people care little about healthy diet.BHuman beings use animals for a wide variety of purposes, including research. B
17、y studying animals, it is possible to learn information that cannot be learned in any other way. Animals are used in research when there is a need to find out what happens in the whole living body. There are four main reasons why animals are used in research.Adding to scientific knowledge through ba
18、sic biological research helps us understand how living things work, and use that understanding for the benefit of both humans and animals. The study of animals is an important part of the whole research process. The bodies of animals are like humans5 in the way that they perform many important funct
19、ions such as breathing, movement, sight, and hearing. To treat disease, doctors and scientists must understand how the healthy body works.Humans and animals share hundreds of illnesses, so animals can act as models for the study of human illness. For example, rabbits suffer from emphysema （月市气肿）， a
20、lung problem that makes it hard to catch their breath. Dogs suffer from cancer, bleeding disorders and so on. Cats suffer from some of the same vision loss as humans. From such models we learn how disease affects the body and more.Once researchers learn more about a particular disease, animals are u
21、sed to develop and test the treatments. For example, medicines for Parkinsons disease have been developed by using animal models with Parkinsons-like symptoms （病症）.Models such as these are an important part of using biological research to solve real medical problems.New medicines need testing becaus
22、e researchers must test both the beneficial and the harmful effects of a medicine on a living body. A medicine must be tested in a suitable animal model before clinical trials （临床试验）in humans can take place.5. According to Paragraph 2, why are animals used in research?A. They may be healthier than h
23、umans.B. Their bodies are simpler than humans.C. They may have the same diseases as humans.D. Their bodies are like humans1 in many functions.6. How does the author support his statement in Paragraph 3?A. By listing figures.B. By giving examples.C. By comparing humans with animals.D. By showing some
24、 research findings.7. The author mentions Parkinsons disease to.A. introduce a new discovery of medicineB. prove that animals have the same diseaseC. explain how to use animals for testing new medicinesD. gives more information about Parkinsons symptoms8. What can we infer from the last paragraph?A.
25、 Testing a new medicine on animals is a must.B. Not all new medicines can be tested in animals.C. New medicines must be first tested in animal models.D. Not all medicines have both beneficial and harmful effects.（三）AA South Korean man and the 21 ducklings he has been raising as his children ever sin
26、ce they hatched have been breaking the internet with their amazing bond. A video that recently went viral in the western world shows the cute birds following their “mother1 on a mountain hike and listening to his every command （指令）.The middle-aged man, whose name is not revealed in the video, has be
27、en taking care of his 21 ducklings ever since they were eggs, making sure the incubation （孵化）period went smoothly, and even helping the tiny birds break through their shell when it came time to hatch. He was the first thing they laid eyes on in this world, and he has remained the most important figu
28、re in their lives since.Ducklings naturally follow their mother around, and since the man was the one who acted as their mother, these birds follow him everywhere, even up a mountain. To them its only natural, but the middle-aged man considers it training and conditioning for the time when he finall
29、y releases （释放） them into the wild. He would love to raise them all as pets, but knows that wouldnt be ideal for him or the birds, so hes making sure that they are strong enough to survive in the wild.The video shows the ducks following the middle-aged man as he hikes up a mountain outside Seoul, st
30、opping whenever he does and refusing to follow anyone else, even if they give the same “lets go command their human mother does. Unless they hear his voice and see him moving, they dont budge. Its actually quite remarkable. I mean, ifs one thing to see dogs acting like this, but ducklings? Thafs som
31、ething else.While ifs not clear what the man does for a living, Im pretty sure he has a lot of experience with ducks, as at one point he reveals a certificate for father of ducklings dated 2005.1.

34、tween Man and AnimalsBBritish scientists have discovered the willow trees planted at an angle （角度） could increase sugars for biofuel production.Willow is fast-growing. It is already used to produce fuels for the renewable heating and power market. In future it could also help to produce biofuel to p
35、ower vehicles. It has been known that when willows growing in the wild are blown sideways they produce more sugars. But for a while it has not been known why this happens.Researchers at Imperial College London, led by Dry Nicholas Brereton and Dry Michael Ray of the Department of Life Sciences, have
36、 now solved the mystery. When the tree is blown sideways, its genes （基因） produce large numbers of sugar molecules （分子）to straighten the tree upwards.“This is an important breakthrough. Our study now shows that natural genetic changes are related to these differences. And this could well be the key t
37、o unlocking the future for green energy from willow, said Dry Brereton.The research was carried out under lab conditions. The willows were grown at an angle of 45 degrees. They were compared to willows which grow naturally straight upwards. The team then looked for the same effect among the willows
38、growing on the Isle of Orkney where strong winds cause the trees to bend at extreme angles. They discovered that the Orkney trees produce five times the amount of sugars found in willows grown in sheltered conditions.Willow is widely planted across the UK. The results show that biofuel crops such as
39、 willows could be grown in climatically challenging conditions where chances of growing food crops are limited.The study is published in Biotechnology for Biofuels.5. What may happen when w川ows are planted in strong winds?A. They will stop growing.B. They w川 grow sideways.C. Few sugars w川 be produce
40、d.D. Changes in genes will take place.6. What can we learn from the text about the Orkney willows?A. They are unusually rich in sugars.B. They grow naturally straight upwards.C. They look taller than ordinary willows.D. They are stronger than those growing in labs.二、选词填空用方框里单词的正确形式填空，使其句意完整。有两个词是多余的
