Diabetes（糖尿病）is caused by a group of metabolic disorder（代谢紊乱) in which there are high blood sugar levels over a long period of time. There are three main types of diabetes:

Type 1 Diabetes results from the body not having enough insulin.(胰岛素)

Type 2 Diabetes mainly happens to those who do not have enough physical exercise, eat too much unhealthy food and get too heavy.

Gestational Diabetes(妊娠期糖尿病)is the third main form. It appears when a woman is having a baby. She will probably get well again after the birth of the baby.

Diabetes can bring serious problem. People with diabetes, especially the Type1, will easily get thirsty and hungry, and quickly lose weight. If it is not treated, it will develop rapidly(weeks or months), and cause many long-term complications(并发症). All the complications related to damage to blood vessels(血管). For example, damage to the eyes. It is caused by damage to the blood vessels in the eyes, and results in gradual vision loss and blindness. The complications will greatly aggrandize the risk of diabetes, by which about 75% of the deaths are caused.

According to a report from the WHO(World Health Organization) in 2015, about 415 million people have diabetes worldwide, which means 8.3% of the adults in the world have diabetes. Of all the cases, 85% to 90% are Type 2 Diabetes. That is to say, most cases of diabetes result from the unhealthy life style. Diabetes doubles a person's risk of early death. From 2012 to 2015, about 1.5 to 5 million deaths each year resulted from this disease. The global economic cost of diabetes in 2014 was around 612 billion USD.

A healthy life style can help prevent diabetes. Doing a lot of physical activities and having a healthy diet will help have normal body weight. Higher levels of physical activity (more than 90 minutes per day) can reduce the risk of diabetes by 28%. Healthy diet includes foods rich in whole grains and fiber, foods with good fats from nuts, vegetable oils and fish, little sugar, and less red meat.

1.Diabetes is ________.

A.a serious disease B.a damage to blood vessels

C.an unhealthy life style D.an unusual blood sugar level

2.According to the passage, what problem can diabetes cause?

A.A person gets too heavy. B.A person doesn't want to eat.

Now I know that we black people are much more likely to have high blood pressure and diabetes (糖尿病) than white people. And they often lead to heart attacks and other untreated diseases. For example, black people are three to four times more likely than white people to have high blood pressure and twice as likely as the white population to die of a stroke (中风).

New research has found out the surprisingly high levels of salt in many of black people’s favorite meals. I stopped putting extra salt in my food at the table long ago and I try to cut down on the salt. I use in cooking. The suggested daily level of salt for adults is 6 grams. It is easy to see that if you try not to eat too many processed (加工过的) foods and use salt in your cooking within the limit, you won’t reach more than the daily level.

The research showed how much salt there is in some foods that we buy from restaurants and takeaways. An average salad with rice and peas has 6.2 grams of salt. This is more salt than you are supposed to eat for the whole day.

A researcher talked about the importance of home cooking rather than take-outs. At home, he pointed out, not only can you hold control of the salt bottle, but also you can create tasty food which is low on salt. The researcher later provided curry goat and rice and peas. They were low on salt, but completely delicious.

I do not suppose Jamaicans are going to stop buying takeaways soon. But if you suffer from high blood pressure, it is probably better not to buy them often.

1.The underlined word “they” in Paragraph 1 refers to _______.

A．white people                          B．black people

C．untreated diseases                      D．high blood pressure and diabetes

2.What has the new research found out according to Paragraph 2?

A．Black people take in too much salt.

B．Black people’s meals are very special.

C．Processed foods have too much salt in them.

D．6 grams of salt per day is enough for an adult.

3.What would the writer probably suggest black people do?

A．Order no salad in a restaurant.             B．Take in no salt for several days.

C．Stop cooking their favorite meals.           D．Eat less takeaways.

4.The researcher provided curry goat and rice and peas in order to _______.

A．thank those who came to his home for his research

B．let people know that eating less salt makes one healthier

C．show that tasty food with less salt can be made at home

D．prove the less salt the food has the more delicious it is

5.What would be the best title for this passage?

A．Watch the salt                          B．Take care, black people

C．Say no to takeaways                     D．Say no to high blood pressure

There are four million people with diabetes (糖尿病) in the UK—that’s one in every 16 people. There are two main types of diabetes: Type 1 and Type 2. Type 1 is less common and is not preventable. In the UK, 90% of diabetes are Type 2. It has something to do with weight gain and a sedentary (久坐的) lifestyle, but there are other risk reasons. The good news is that around 80% of cases of Type 2 diabetes are preventable.

Are you at risk?

Type 2 diabetes can come on slowly. It may not be easy to find the signs. So it is important to understand the risk reasons. People with Type 2 diabetes can feel thirsty, tired and need to go to the toilet more often.

Tips on preventing Type 2

If you have Type 2 diabetes, it is very important to control your weight. If you are overweight, Type 2 diabetes can be avoided by reducing your weight.

Exercise is necessary for good health. It not only helps to keep a healthy weight, but can lower blood-sugar levels because it helps your body to use insulin (胰岛素) more effectively. To have high levels of everyday activities, including walking, housework, playing with children and hobbies—anything that gets you moving.

Also, a healthy diet will help you manage your weight. Vegetables and fruits are low in calories and are rich in vitamins, minerals (矿物质) and fiber (纤维). This is important for good digestion (消化) and slows down the sugars into the blood. However, some types of fruits are high in sugar, so getting most of your five-a-day from vegetables is better.

Whole grains are good for Type 2 diabetes because the husk (外壳) of the seed is kept. This is often the best part of the grain, with fiber and protein (蛋白). Protein is good for Type 2 diabetes. Fish, meats, eggs, nuts and many beans are rich in protein.

Foods high in both fat and sugar are very bad for your health and should be avoided. Water is the best because there aren’t any calories in it while many other drinks, such as soft drinks, energy drinks and milky coffees are really bad.

Tide is the regular rise and fall of the ocean level caused by the movement of the sun, the earth and the moon. It is considered a promising source of green energy to produce electricity in coastal areas.

To make use of tidal energy, we need to build tidal power stations. The bays and the river mouths where the tide is high (the tidal range is more than 10 metres) are usually perfect sites to build tidal power stations. There are many such places in the world. According to the IRENA (the International Renewable Energy Agency), by just using 2% of our coastlines, we can produce 4, 383TWh of ocean power each year, enough to meet 16. 4% of the world's electricity needs.

To build a tidal power station, we need to build a dam. In the dam are many turbines and on each turbine there is an electric generator. When the tide rises, water comes through the dam, the turbines turn and the electric generators work, producing electricity. When the tide fall, water goes out through the dam, the turbines turn again. The electric generators continue to work.

Tidal energy has it advantages. Using tidal energy to produce electricity is much cheaper than using the traditional energy, like coal or gas. For example, the Rance Tidal Power Station in France has been there for over 50 years, producing around 540, 000TWh of electricity each year. The cost is only 1.3 cents/TWh. Tidal energy can be used nearly 24 hours a day. As long as the sun, the earth and the moon exist, we can use it to produce electricity. But without sunshine, here is no solar energy. When there is no wind, electric generators will not work. In addition, with the development of modern technology, tidal energy can be stored and used to produce electricity continuously. However, we still have some problems to solve. It is difficult to build a dam in the sea, and the cost is very high. Moreover, it's expensive to keep a tidal power station in is best condition.

Scientists are working on them.

1.A tidal power station is best built __________.

A.at a river mouth with wind B.along the coast with waves

C.in a bay with tide high enough D.in coastal areas with sunshine

2.The underlined word "turbine" in Paragraph There is a machine to__________.

A.make the tide rise and fall B.make an electric generator work

C.let water go through the dam D.keep the dam in good condition

3.What advantage does tidal energy have?

A.We can use it to get useful tide. B.It can improve the ocean environment.

C.We can use it nearly all the time. D.It meets 16. 4% of the electricity needs.

4.How can we make better use of tidal energy?

A.By digging more bays and river mouths.

B.By building cheaper tidal power stations.

C.By closing traditional electric power.

D.By using tidal energy to replace other energy.

Sometimes, laughter can help us discover the beauty of life. Whether it's caused by joy or embarrassment, it's an indispensable(不可或缺的) part of life.

Just now, an old photo reminded me of an unforgettable experience. When I was twelve years old, my family flew to America to go on a trip. The fantastic places of interest left me good memories. However, on the last day of the journey, I made a funny mistake.

That evening, my mother asked me to buy some food by myself. I ran to the supermarket happily. After a while, I put a few things, including a bag of bone-like biscuits, into the shopping basket that I had brought from home.

When I came back to the hotel, I asked my mom if she took pride in me. Suddenly, she started laughing loudly. I had no idea what had made her laugh so much. A few minutes later, she explained to me that the bag of biscuits was dog food. She looked at me and pointed at the English words on the bag, laughing again. At that moment, I felt so awkward(尴尬的) that my face turned red right off. And I realized that I could never be too careful.

As time goes by, I've forgotten a number of things, but this memory is still clear. Life won't be colorful unless we can find beauty in little things like this. Don't you think so?
