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. Scientists say the lakes take on such colors because the volcanic gases met the lakes’ minerals centuries ago.

1.People who hike Mount Mayon can enjoy the following EXCEPT .

C. views of the Cagsawa Ruins

D. views of Indonesia’s East Nusa Tenggara province

2.According to the text, Kilauea .

A. is an active volcano

B. stopped erupting in 1983

C. is the youngest volcano in the world

D. forces thousands to flee in 2014.

Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.

The largest study of the effects of aging on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.

“We have found that the power of the male heart falls by 20--25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.

“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the aging process.”

What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.

“This gender difference might just explain why women live longer than men,” said Goldspink.

They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease.

The team has yet to find why ageing takes a greater loss on the male heart, said Goldspink.

The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

1.The underlined word “longevity” in the second paragraph probably refers to ______.

A. health B. long life C. aging D. effect

2.The text mainly talks about ______.

A. men’s heart cells B. women’s aging process

C. the gender difference D. hearts and long life

3.According to the text, the UK scientists have known that ______________.

A. women have more cells than men when they are born

B. women can replace the cells that enable the heart to beat

C. the female heart loses few of the cells with age

D. women never lose their pumping power with age

4.If you want to live longer, you should ___________.

A. enable your heart to beat much faster

B. find out the reason for aging

C. exercise regularly to keep your heart healthy

D. prevent your cells from being lost

5.We can know from the passage that __________.

A. the reason why aging takes a greater loss on the male heart has been found out

B. scientists are on the way to finding out why the male heart loses more of the cells

C. the team has done something to prevent the male from suffering the greater loss

D. women over 70 could lose more heart cells than those at the age of 20

Before going outside in the morning, many of us check a window thermometer(温度计)for the temperature. This helps us decide what to wear. ____1.____. We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven. If we don’t feel well, we use a thermometer to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in the summer.

Not all the thermometers use the same system to measure temperature. We use a system called the Fahrenheit scale. But most other countries use the Centigrade scale.

Both systems use the freezing and boiling points of water as their guide.___ 2.___ .

The most common kind of thermometer is made with mercury(水银)inside a clear glass tube. As mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts(收缩). That is why on hot days the mercury line is high in the glass tube.____ 3.___.

First. Take a clear glass juice bottle that has a cap ; fill the bottle with coloured water. Tap a hole in the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw(吸管) through the nail hole.

_____4.____.

Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily.

_____5.____.

As the temperature goes down, the water will contract, and the lever in the straw will come down. Perhaps you will want to keep a record of the water lever in the straw each morning for a week.

A.We use and depend on thermometers to measure the temperature of many other things in our daily lives.

B.Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled.

C.Now that you know this rule you can make a thermometer of your own that will work.

D.The water will rise in the straw. As the temperature of the air goes up, the water will expand and rise even higher.

E.They label these in different ways. On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees. On the Celsius scale water freezes at 0 degrees and boils at 100degrees.

F.Take wax (you may use an old candle if you have one) and melt some of it right where the straw is struck into the cap to seal把..粘住) them together.

G.People use thermometers which are made by themselves when travelling around the world.

How can I fight laziness?

Lazy people will never amount to anything in life. However, laziness can be defeated once a few changes have been made in your mind.

___1.____ . Many people lack sleep constantly, since they stay up too late and get up too early to prepare for work. These people have little motivation once they arrive home. Laziness works hand in hand with a lack of motivation and a tendency to put off things. By adjusting your sleep schedule to provide a few more hours of meaningful rest, you can fight laziness throughout the day.

Another way to fight laziness is to change your mind from passive to active. Some people treat their lives as if they were pushed from task to task. Others take a more proactive approach, viewing each task as a challenge they must overcome alone. __2.____

Some people fight laziness by removing the temptations(诱惑) that surround them. A television in the living room may provide entertainment, but watching too much TV often contributes to laziness. Create a reward system for yourself, just as parents do for a child to promote responsibility. __3.___

__4.____ Spouses(配偶) and children may all have different energy levels, but laziness can be spread if not dealt with immediately. To fight household laziness, lead by example. Be the first to collect and wash dishes after a meal. Others in the home may eventually follow your example and perform their own task. It is difficult to practice laziness when you are surrounded by motivated people.

____5.__ enough exercise and a balanced diet can help you to develop a healthy lifestyle, thus enabling you to have more energy and help lift your spirits.

A. Knowing how to fight laziness is important.

B. Laziness sets in when you no longer feel in charge of your own life.
