A

A South Korean man and the 21 ducklings he has been raising as his children ever since 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 “mother” 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 been 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 figure 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 it’s only natural， but the middle-aged man considers it training and conditioning for the time when he finally releases （釋放） them into the wild. He would love to raise them all as pets， but knows that wouldn’t be ideal for him or the birds， so he’s 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， stopping whenever he does and refusing to follow anyone else， even if they give the same “l(fā)et’s go” command their human mother does. Unless they hear his voice and see him moving， they don’t budge. It’s actually quite remarkable. I mean， it’s one thing to see dogs acting like this， but ducklings？ That’s something else.

While it’s not clear what the man does for a living， I’m 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. What can we learn from the video？

A. The ducklings just broke through their shells.

B. The man accidentally saved some ducklings.

C. The ducklings just obeyed the man naturally.

D. The man took pride in his ducklings.

2. What’s the man’s purpose of raising the ducklings？

A. To make a living by performing.

B. To film a video to attract attention.

C. To free them into the wild one day.

D. To make a contribution to a bird reserve.

3. What word can best replace the underlined word “budge” in Paragraph 4？

A. Stop. B. Move.

C. End. D. Fight.

4. What can be the best title for the text？

A. “Father” and “Mother” of Cute Pets

B. Man Raises Ducklings as His “Children”

C. Ducklings Also Regarded as Good Pets

D. Amazing Bond Between Man and Animals

British 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 power 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 Dr Nicholas Brereton and Dr Michael Ray of the Department of Life Sciences， have 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 to unlocking the future for green energy from willow，” said Dr 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 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 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 willows are planted in strong winds？

A. They will stop growing.

B. They will grow sideways.

C. Few sugars will be produced.

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.

7. Farmers living in challenging climate ___ .

A. use biofuel for heating and power

B. are encouraged to grow biofuel crops

C. can plant different kinds of food crops

D. should make their willows grow straight

8. Where does this text probably come from？

A

Many 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. 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 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. A kind of white butterfly will 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 （多樣化飲食）. The bear eats fruits and fish. The fox eats small animals， birds and fruits. The diet of these animals will be different 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 animal 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 animals

___ .

A. depend on the same sense in choosing food

B. choose food by their look and smell

C. choose food in similar ways

D. eat entirely different food

2. 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 by 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.

B

Human beings use animals for a wide variety of purposes， including research. By 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 basic 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 humans’ in the way that they perform many important functions 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 （肺氣腫）， a 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 used to develop and test the treatments. For example， medicines for Parkinson’s disease have been developed by using animal models with Parkinson’s-like symptoms （癥狀）. Models such as these are an important part of using biological research to solve real medical problems.

New medicines need testing because 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 （臨床試驗） in humans can take place.

5. According to Paragraph 2， why are animals used in research？

A. They may be healthier than humans.

B. Their bodies are simpler than humans’.

C. They may have the same diseases as humans.

D. Their bodies are like humans’ 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 research findings.

7. The author mentions Parkinson’s disease to ___ .

A. introduce a new discovery of medicine

B. prove that animals have the same disease

C. explain how to use animals for testing new medicines

D. give more information about Parkinson’s symptoms

8. What can we infer from the last paragraph？

A. 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.

Evaluating Sources （來源） of Health Information

Making good choices about your own health requires reasonable evaluation （評估）. A key first step in bettering your evaluation ability is to look carefully at your sources of healthy information. Reasonable evaluation includes knowing where and how to find relevant information， how to separate fact from opinions， how to recognize poor reasoning， and how to analyze information and the reliability of sources.

Go to the original source. Media reports often simplify the results of medical research. Find out for yourself what a study really reported， and determine whether it was based on good science. Think about the type of study.

Watch for misleading language. Some studies will find that a behavior “contributes to” or is “associated with” an outcome; this does not mean that a certain course must lead to a certain result.? Carefully read or listen to information in order to fully understand it.

Use your common sense. If a report seems too good to be true， probably it is. Be especially careful of information contained in advertisements.? Evaluate “scientific” statements carefully， and be aware of quackery（江湖騙術(shù)）.

Friends and family members can be a great source of ideas and inspiration， but each of us needs to find a healthy lifestyle that works for us.

Developing the ability to evaluate reasonably and independently about the health problems will serve you well throughout your life.

A. Make choices that are right for you.

B. The goal of an ad is to sell you something.

C. Be sure to work through the critical questions.

D. And examine the findings of the original research.

E. Distinguish between research reports and public health advice.

F. Be aware that information may also be incorrectly explained by an author’s point of view.

G. The following suggestions can help you sort through the health information you receive from common sources.

The strength of TC Williams High School in Alexandria， Virginia is its diversity （多樣性）， says Shawn Lowe， a science teacher at the school. Her students are interested in doing science fair projects， but don’t have enough money to pursue them.

“Having equipment available 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 students as they completed projects to present at science fairs—three times the previous number of students.

“Without the grant， I would not have had the freedom to buy the equipment needed，” Shawn said. “The grant has directly influenced about 20 science fair projects that would otherwise not be available. 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 allowed Shawn to buy materials for a group of students to build a drone （無人機(jī)）. “Without these materials， we would not have been able to build a drone， and wouldn’t 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 automatically （自動地）. 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 won’t end there. Many will go on to study STEM subjects in college， including the students who built the drone 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 don’t get the support of the school.

D. They don’t have confidence after many failures.

2. What does the underlined word “grant” in Paragraph 4 most probably mean？

A. Money. B. Interest.

C. Agreement. D. Equipment.

3. What does the underlined word “it” 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 a suitable university.

C. The different choices of students after high school.

D. The great influence of doing science projects at school.

Water

Not getting enough water will stop your brain from working well. And remember， water isn’t as expensive as sweet drinks！

Your brain needs several hours’ sleep， so it can “update” itself， just like a computer. Experts say that when you study for a test or exam， you should get some sleep as quickly as possible after you’ve finished studying. This helps you to remember what you’ve learnt.

A. A short break.

B. A good night’s sleep.

C. It works best in the morning.

短文改錯

In our life， we often regret what we did and which we couldn’t do. Actually， it doesn’t benefit us at all. As for most of us， we missed many chance to earn more money， to get a high position and to realize our dreams. We often regret that we don’t seize those opportunities， thus feel upset. Although we do know regretting the past is no benefit， but we still can’t help doing it.

To avoid the problem below， we need to pay more attention to what you are doing now， making us busier and having no time to recall the past. Moreover， we’d better set reasonably goals one by one. Only by doing so can we struggle for our future better.
