Soda is refreshing and delicious, but it is not part of a healthy, balanced diet. Most sodas are packed with sugar. In fact, a can of soda can be hiding up to 10 teaspoons of sugar! The sugar does make soft drinks delicious, but definitely not nutritious. Too much sugar in a person’s diet can lead to diabetes (糖尿病), heart disease, and tooth problems. One of the biggest sugary soda problems is that drinking much can lead to weight gain and even obesity.

There are diet options available for almost every kind of pop (汽水), which means that you don’t have to drink all that sugar in order to enjoy a can of soda. Many studies have been done on whether or not aspartame (甜味剂), the sugar substitute in diet soda, is bad for you. Up to now, there are still conflicting opinions on this issue. The European Food Safety Authority recently concluded that aspartame is safe for most people, even in fairly large amounts. Aspartame still might not be good for you, though. Studies have shown that people who drink diet sodas may actually gain more weight than those who drink regular soda, perhaps because, strangely enough, drinks loaded with fake sugar may actually make you want to eat more.

Maybe you’ve decided it’s time to cut down on your soda drinking, but what should you drink instead? Water is absolutely the healthiest thing that you can drink. Your body needs water to stay hydrated (水合物) and function properly, and water contains no calories or fat. Drinking fruit juice occasionally is not a bad thing, but you should be careful what juice and how much juice you’re drinking. Fruit juices can contain almost as much sugar as pop!

As with most things to do with your health, moderation is really at the base of any healthy diet. You can totally drink soda, even the sugary kind just, make sure you’re not drinking too much!

1.What can we know about sugar in Paragraph 2?

A. Sugar is a necessary material in making Soda.

B. Sugar can make Soda delicious and nutritious.

C. Too much sugar may cause health problems.

D. Sugar can lead to much fat or even obesity.

2.What does the author think of aspartame in diet Soda?

A. He believes large amounts of aspartame is safe for people.

B. He agrees that aspartame might not be good for health.

C. He thinks that aspartame may do great harm to health.

D. He insists that aspartame is much safer than sugar.

Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.

The first is called the " tank(贮水池) test". A modem airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构)of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is try­ing to get out. If a small part of the plane were to fail, the plane would explode (爆炸)in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air.  The pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger.

The most dangerous test happens when the new plane is going through test flights in the air. The pilot must find out exactly what happens when the engines (发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot’s job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.

1.By doing the "tank test", the engineers can find out _______.

2.What will happen to the plane under the "tank test"?

3.According to the text, why are test flights most dangerous?

4.What might be the most suitable title for the text?

It is true that world population is growing, but this is not the cause of our current and future global problems. Believing this will cause us to ignore the real problem and risk long-term damage to our planet.

Let me start by explaining why overpopulation is a myth. For one thing, the UN Population Division regularly predicts population growth but provides a low variant　 (变量), medium variant, and high variant to factor in various possibilities. In the 2010 revision, their high variant suggests that the world population will be almost 16 billion in 2100, but the low variant predicts it will peak at 8 billion and decrease to just over 6 billion by 2100. In most cases, it is the low variant that has come true in the past, suggesting the same will be true of their future population predictions. In addition to this, the size of families is actually decreasing.

For another, if the Earth is overpopulated, there needs to be insufficient (短缺) food, water, and space for humans to live. However, Indian economist Raj Krishna estimates that India alone is able to increase crop produce to the point of providing the entire world’s food supply. The World Food Programme confirms that there is sufficient food grown to feed the world and there is the same amount of fresh water on the planet now as there was 10,000 years ago. So how is it possible that the number of people in the world is affecting our planet?

Therefore, it is not an increase in population but an increase in consumption that is a severe threat. Materialism and overconsumption are facts of life for everybody in the western world, as possessions reflect a person’s status in society and people strive to obtain happiness through owning the latest fashionable goods. Not only that, but waste is a common occurrence which has a huge effect on our resources. It is a sad truth that 80% of the world’s resources are currently used by just 20% of the world’s population.

Our overconsumption must be addressed now to make our lives more sustainable (可持续的) and avoid continuing the terrible damage to the environment we are causing. The key is education. If we do not work towards this but instead focus on the wrong issue, we may find ourselves living on a planet that can no longer sustain human life.

1.According to the author, what causes our current and future global problems?

A. The increase in population.

B. Shortage of food and water.

C. The fast growth of material needs.

D. Failure to protect the environment.

2.The underlined word “myth” in Paragraph 2 is closest in meaning to _________.

A. fact　　 B. misunderstanding　 C. possibility　 D. uncertainty

3.The author stresses that _____.

A. people should save food and water

B. economists are making wrong predictions

C. wrong judgment leads to serious consequences

D. measures should be taken to reduce population

4.What is mainly discussed in the passage?

A. The real cause of global problems.

B. The severe effect of overpopulation.

C. Reasonable use of natural resources.

D. Methods to reduce overconsumption.

Honey from the African forest is not only a kind of natural sugar, it is also delicious. Most people, and many animals, like eating it. However, the only way for them to get that honey is to find a wild bees' nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper—a little bird called a honey guide.

The honey guide does not actually like honey, but it does like the wax in the beehives(蜂房). The little bird cannot reach this wax, which is deep inside the bees' nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey, and the wax(蜂蜡), always falls to the ground, and this is when the honey guide takes its share.

Scientists do not know why the honey guide likes eating the wax, but it is very distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.

1.Why is it difficult to find a wild bees' nest?

A. It's small in size. B. It's hidden in trees.

C. It's covered with wax. D. It's hard to recognize.

2.What do the words "the follower" in Paragraph 2 refer to?

A. A bee. B. A bird.

C. A honey seeker. D. A beekeeper.

3.The honey guide is special in the way ______.

A. it gets its food B. it goes to church

C. it sings in the forest D. it reaches into bees' nests

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

A. Wild Bees B. Wax and Honey

C. Beekeeping in Africa D. Honey-Lover's Helper
