Deborah Cohen is a senior natural scientist at the Rand Corp and the author of the book A Big Fat Crisis: The Hidden Forces Behind the Obesity Epidemic and How We Can End It. According to the book, there are lots of misunderstandings of obesity.
1. If you’re obese, blame your genes.
Obesity rates have increased. Yet, between 1980 and 2000, the number of Americans who are obese has doubled—too quickly for genetic factors to be responsible.
At restaurants, a dollar puts more calories on our plates than ever before, because restaurant meals usually have more calories than what we prepare at home, so people who eat out more frequently have higher rates of obesity than those who eat out less.
2. If you’re obese, you lack self-control.
Research shows that if we are faced with too much information, we have a tendency to make poor dietary choices. Our world has become so rich in temptation that we can be led to consume too much in ways we can’t understand. Even the most vigilant(警觉的) people may not be up to the task of controlling themselves.
3. Lack of access to fresh fruits and vegetables is responsible for obesity.
Although the US Department of Agriculture estimates that fewer than 5 percent of Americans live in the “food deserts”, about 65 percent of the nation’s population is overweight or obese. For most of us, obesity is not related to access to more fresh fruits and vegetables, but to the choices we make in supermarkets.
4. The problem is not that we eat too much, but that we don’t exercise.
Michelle Obama’s “Let’s Move” campaign is based on the idea that if kids exercise more, childhood obesity rates will decrease. But there was no significant decrease in physical activity levels as obesity rates climbed in the 1980s and 1990s. In fact, although a drop in work-related physical activity may account for up to 100 fewer calories burned, leisure physical activity appears to have increased. The problem is that we eat too much.The author mentioned Deborah Cohen’s book in Paragraph 1 to _______.

A castle is a type of fortified（加固的）structure built in Europe and the Middle East during the Middle Ages. This is different from a palace, which is no fortified-though there are many similarities among these types of construction. Usage of the term has varied over time and has been applied to diverse structures.
The European castles originated in the 9th and 10th centuries, resulting in its land divided among nobles. These nobles built castles to control the area surrounding them, and they were both offensive and defensive structures. Although army uses are often emphasized in castle studies, the structures also served as centres of administration and symbols of power. Urban castles were used to control the local people and important travel routes, and rural castles were often built near farmland.
Many castles were originally built from earth and wood, but had their defences supplanted later by stone. In the late 12th and early 13th centuries, scientific approaches to castle defence appeared, and could function to maximize the castle’s firepower. These changes in defence came from a mixture of castle technology. Although gunpowder was introduced to be built well into the 16th century, improved cannon（大炮）fire made them uncomfortable places to live in. As a result, true castles went into decline.
From the 18th century onwards, there was a renewed interest in castles with the construction of mock（仿造的）castles, part of a romantic revival（复活）of Gothic architecture, but they had no defensive purpose.According to the first paragraph, we can know .
| A．the palace is a fortified structure |
| B．the castle is different from the palace |
| C．the palace changed over time |
| D．the structures of the castle in different ages look the same. |
what does the second paragraph mainly talk about?
| A．Symbols of the European castles. |
| B．Functions of the European castles. |
| C．Influences of the European castles. |
| D．Characteristics of the European castles. |
The underlined word “ supplanted ” in the third paragraph is closet in meaning to “ “.
| A．produced | B．saved | C．protected | D．replaced |
What can be inferred from the river?
| A．Castles have nothing in common with palaces. |
| B．Castles have a history of more than 1,000 years in Europe. |
| C．Castles were mainly used for defensive purposes after the 18th century. |
| D．The introduction of gunpowder instantly influenced castle building in Europe. |
Photography has been my interest ever since I was old enough to pick up a camera, but today I want to share with you the 15 most treasured photos of mine, and I didn’t take any of them. There were no art directors, no stylists, no chance for reshoots, not even any regard for lighting. In fact, most of them were taken by random tourists.
My story begins when I was in New York City for a speech, and my wife took a picture of me holding my daughter on her first birthday. We’re on the corner of the 57th and 5th avenue. We happened to be back in New York exactly a year later, so we decided to take the same picture.
Well you can see where this is going. Approaching my daughter’s third birthday, my wife said, “Hey, why don’t you take Sabina back to New York and make it a father-daughter trip, and continue the ceremony?” This is when we started asking passing tourists to take the picture.
So these photos are far more than representatives for a single moment, or even a specific trip. They’re also ways for us to freeze time for one week in October and reflect on our times and how we change from year to year, and nor just physically, but in every way. Because while we take the same photo, our viewpoints change, and she reaches new milestones and I get to see life through her eyes, and how she communicates with and sees everything. This very focused time we get to spend together is something we value and expect the entire year.What can we know about the author from the first paragraph?
| A．He is fond of being photographed alone. |
| B．He hardly ever asks strangers to take pictures of him. |
| C．He has been interested in photography since childhood. |
| D．He’s proud of the 15 most treasured photos taken by himself. |
Who came up with the idea of having a father-daughter trip when Sabina was 3 years old?
| A．Her mother. | B．Her father. |
| C．Sabina herself | D．An unknown tourist. |
It can be inferred from the last paragraph that .
| A．children usually get to see life through adults’ eyes |
| B．the 15 photos are meaningful to the author’s family |
| C．it takes the author a whole week to have a family photo taken |
| D．the viewpoints of the author’s family never change with the time. |
What can be the best title of the text?
| A．Believe it or not; photos do change |
| B．Photos help a family become rich |
| C．Even strangers can help take photographs |
| D．A father-daughter bond, one photo at a time |
Are you a volcano lover? Here is a list of some of the world’s most beautiful volcanoes that our travel agency can offer you to visit. Don’t miss them!
Mount Mayon, the Philippines
Located about 450 km southeast of Manila on the island of Luzon, Mount Mayon is the most active volcano in the Philippines; a September 2014 eruption forced thousands to flee the area. Those who hike the volcano are rewarded with views of the towns on the Albay province and the Pacific Ocean. But even those who prefer the view from a distance have historical good point at the Cagsawa Ruins, once an 18th Century Franciscan church that was destroyed by an 1814 eruption.
Kilauea and Mauna Kea, Hawall
Hawaii’s volcanoes are known for their active eruptions and extraordinary scenes. Mauna Kea is around one million years old, while Kilauea is the youngest volcano in Hawaii and has been erupting continuously since 1983. The lava falls straight into the sea, creating fantastic forms of black rocks and smoke clouds.
Mount Kelimutu, Indonesia
Kelimutu’s three mysterious crater lakes attract both scientists and tourists to the island of Flores in Indonesia’s East Nusa Tenggara province. One is emerald green（翡翠绿），another dark red, and the third pitch black.

Like human beings, dogs may catch cold because of cold weather, wet conditions or can also get it from other sick dogs. If a dog has a running nose and watery eyes, coughs or sneezes(打喷嚏）, then it is quite probable that the dog has caught cold.
A dog's cold can get over after a few days without treatment but it totally depends upon the owner to treat it with medications or improve its immune power（免疫力）to get rid of the cold naturally. Following are some of the things you can do if your dog gets a cold.
You can improve its immune power by giving it proper nutrient diet. Healthy food can really do wonders. Try to give it food which is either suggested by the vet（兽医）or is healthy for your pet. Increase the intake of food which is rich in vitamins A, C and E.
Keep your dog warm. The best place for your dog in winter is inside your house. Do not keep your dog outside when it is cold and wet. At home you can also keep the dog warm with the help of carpets. This will make him comfortable and help him to recover fast.
Increase the fluid（流质）intake as it helps a lot. Water can be the best choice but you can also add broth（肉汤）in water which will give your dog strength. Warm water will make your dog more comfortable and will also keep the dog away from the respiratory infections（呼吸道感染）.
Steam treatment is considered to be effective in getting rid of cold. It makes the nasal（鼻的）passage wet, which helps proper breathing. Just fill your bathroom with steam and leave your dog inside the bathroom for 15 minutes. Do it nearly 2 to 3 times a day and you will see your dog recovering.
These are some of the things you can do to help your dog recover from cold. However, if you are not able to find any improvement in its health, then turn to the vet for help immediately. Take your dog for regular checkups so as to avoid complications（并发症）.From the first paragraph we know about __________.
| A．the difficulty in keeping a dog as a pet |
| B．characteristics(特征) of sick dogs |
| C．the similarities between dogs and human beings |
| D．causes and symptoms（症状）of cold in dogs |

When a dog catches cold, it is wrong to ________.
| A．keep it inside during cold and wet weather |
| B．leave it inside the bathroom full of steam |
| C．let it eat too much solid（固体）food |
| D．keep it sleeping on carpets at home |
It can be learnt from the text that _________.

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
My husband, my four-month-old daughter and I set out on a five-day driving journey from California to Washington. We had to stop frequently because our little child needed to stretch from the car seat.
One of our stops, once we crossed the Oregon border, was at a Black Bear Diner. Walking towards the front door we noticed a gentleman standing at one side. He was clearly untidy, without shoes and wearing worn clothing. We passed right by him and opened the restaurant door. Then something told me to go back.
Holding my daughter, I turned around and said to the gentleman, “Sir. Are you hungry?” He said, “Yes.” I then asked, “May we buy you something to eat?” He responded with, “Sure, I can order something myself.”
My husband opened the door and the gentleman went straight to the counter. I told him to order whatever he wanted. The manager of the restaurant came over quite quickly and looked frightened. I spoke before he had an opportunity to. “This gentleman will have lunch with us today,” I said. “Please add his order to our bill.” The manager said with a frown(皱眉), “Okay.” We turned to our table and the gentleman said, loudly and quickly, “Thank You!” We were seated and upon completing our meal we were handed our bill. I asked my husband what the gentleman had ordered. One fresh orange juice, one coffee, one breakfast combination with a side of hash browns.
When we left the restaurant I looked for the gentleman but didn’t see him, but that very small act just made my day. I hope in some small way we were able to add some joy to his life, even if only for a few minutes. From the appearance of the gentleman, we can guess he was probably a(n) _____.
