The massive 8.8 quake, the seventh strongest in recorded history, hit Chile and should have shortened the length of an Earth day by 1.26 milliseconds, More impressive is how much the quake shifted the Earth’s axis(地轴).
The computer mode! Used to determine the effects of the Chile earthquake effect also found that it should have moved the Earth’s figure axis by about 8 cm. The Earth’s figure figure axis is not the same as its north-south axis, which Earth turns around once every day at a speed of about 1,604 kph. The figure axis is the axis around which the Earth’s mass is balanced. It is offset(偏离) from the Earth’s north-south axis by about 10 meters.
Strong earthquakes can change Earth’s days and its axis. The 9.1 Sumatran earthquake in 2004, which set off a deadly tsunami(海啸),should have shortened Earth’s days by 0.0068 milliseconds and shifted its axis by about 7cm.
One Earth day is about 24 hours long. Over the course of a year, the length of a day normally changes gradually by one millisecond, It increases in the winter when Earth more slowly, and decreases in the summer.
The Chile earthquake was much smaller than the Sumatran quake, but its effects on the Earth are larger because of its location. The fault(断层) responsible for the 2010 Chile quake also cuts through Earth at a larger angle that the Sumatran quake’s fault. This makes the Chile fault ore effective in moving the Earth’s mass vertically and hence more effective in shifting the Earth’s figure axis.
The findings are based on early date available on the Chile earthquake. The Chile earthquake has killed more than 700 people and cause widespread damage in the South American country.
64.What’s the biggest problem caused by the Chile quake?
A.It is the seventh strongest in recorded history.
B.It should have shortened the length of an Earth day.
C.It shifted the Earth’s axis.
D.It made the day longer on Earth.

A.the Sumatram earthquake had more effect on Earth
B.the location of the Chile earthquake is responsible for its larger effects on Earth.
C.the Sumatram earthquake was less destructive
D.the Chile earthquake fault changed the Earth’s mass
66.What does the word “it” in the 4th paragraph refer to?
A.The leng of a day. B.The axis.

In one of the strongest indications of the power of the mind to influence the body ,a growing collection of evidence finds that people who are depressed have a greatly higher risk of developing heart disease.
In a study of almost 3,000 men and 5,000 women , depressed men were 70 percent more likely to develop coronary (心脏的)heart disease than those who weren’t depressed. While depressed women were just 12 percent more likely to develop heart disease. Those who were severely depressed were 78 percent more likely.In fact ,a 1998 study found that women who are depressed have a risk of dying from heart disease equal to that of women who smoke or who have high blood pressure.
The link works the other way around, too: While about 1 in 20 American adults experience major depression in a given year, that number jumps to about one in three among those who have survived a heart attack.
The more severe the depression, the more dangerous it is to your health .But some studies suggest that even mild depression ,including feelings of hopelessness experienced over many years ,may damage the heart. Other studies suggest depression may affect how well heart disease medications work.
Researchers aren’t sure what the connection between depression and heart disease is, but theories exist. One is that people who are depressed tend not to take very good care of themselves. They’re more likely to eat high –fat ,high-calorie “comfort ”foods ,less likely to exercise ,and more likely to smoke. But beyond lifestyle ,there is probably also a physiological link between depression and heart disease. Recent studies found that people with severe depression tended to have a lack of heart-healthy O-3 fatty acids. People who are depressed also often have high levels of stress hormones (荷尔蒙)These keep the body primed for fight or flight ,raising blood pressure and causing the heart to beat faster, all of which put additional stress on coronary arteries (动脉)and prevent the body’s natural healing mechanisms from working properly.
A whole branch of medicine is devoted to the complex links between mental health ,the nervous system, the hormone system and so on. This science is gradually soring out how the mind- body connection affects us , or defense against heart disease.
Generally, an estimated 10 percent of American adults experience some form of depression every year. Although available treatments can east symptoms (症状) in more than 80 percent of people treated, less than half of those with depression get the help they need .
1.Which of the following can be the best title of the passage?
A. Depression -----Heart Disease Risk Factor B. Heart Disease---- Health Killer
C. Depression ---- Mental Health Enemy D. Heart Disease ---- Depression Factor
2.Which statement is NOT true the passage?
A. With high blood pressure,depression is another potential risk to women’s health.
B. Depression,which is mild,can possibly cause damage to your health
C. Most people who experience depression get treated as they should be
D. Depression may have some influence on the function of heart disease medication
3.According to the passage ,the possible connections between heart disease and depression are the following EXCEPT______________
A. Depressed ones tend to eat high fat and high –calories food ,which leads to physical damage to heart
B. Severe heart disease may cause people to feel hopeless and depressed
C. Depression may result in the lack of some kind of acids ,which probably affects the working of people’s heart.
D. People with depression often have a high level of stress hormones ,maybe ,which will put extra pressure on one’s heart.
4.We can infer from the passage that _________
A. More researches will be done to find the certain links between heart disease and depression
B. The percentage of adults with depression is higher than that of depressed adults with heart disease .
C. One’s life style has relatively little relationship with one’s mental health.
D. Those with depression have a higher risk of developing heart disease.

Deep in the middle of Sri Lanka, a massive column of rock reaches out from the green tropical forest. It is 660 feet tall and features frescoes (壁画), graffiti, and landscaped gardens.
The rock is known as Sigiriya and holds a special place in the island's cultural history.
It was established as the stronghold of a king over 1,500 years ago, and today the Sigiriya complex stands as one of the earliest preserved examples of ancient urban planning.
Located in the Central Province, the column of rock is somewhat central to the country. The rock is known as Sihagiri, meaning "Lion Rock", a nod to the giant animal carved from stone which greeted visitors at the entrance.
In 476 BC. King Dhatusena ruled over Sri Lanka. One of his illegal sons, Kashyapa, wanted the throne (王位). Kashyapa overthrew Dhatusena and drove his brother Moggallana to Southern India. Kashyapa crowned himself king in 477 BC.
King Kashyapa chose Sigiriya as his palace because its position was an advantage to the defensive stronghold, offering fantastic 360-degree views. Plans to build a city quickly unfolded and after several years, the Sigiriya complex had become a business center for the new King.
Sigiriya was both a palace and a fortress (堡垒); the overall complex featured five gates and measured just under 3 km by just over 1 km. The site plan consisted of a fort,an upper palace on the top of the rock,and lower palaces at ground level. The king also constructed gardens throughout,and for protection a river with walls surrounded the complex.
Frescoes decorate the western side of the rock, along with the mirror wall, a brick face covered in a highly-polished white plaster. When new, the wall was said to be able to produce Reflections.
Over time the Mirror Wall became a graffiti board, covered in verses written by visitors. Known as "Sigiri Graffiti", some of the messages date to the 8th century CE.
1.It is implied in the passage that Sigiriya was built to ______________.
A.preserve the culture of Sri Lanka B.prove the ancient urban planning
C.keep the King from being attacked D.protect the green tropical forest
2.According to the passage, some visitors would _________.
A.have a reflection before the Mirror Wall
B.leave comments on the Mirror Wall
C.draw beautiful paintings of girls on the wall
D.be lost in thought before the Mirror Wall
3.What do we know about Sigiriya?
A.Its entrance is carved like a lion. B.Its gardens are at ground level.
C.Its western side is a mirror. D.Its palaces are on the top of the rock.
4.What is the best title of the passage?
A.The giant lions in Sri Lanka. B.The pearl of the Indian Ocean.
C.The Lion Rock of Sri Lanka. D.The mirror wall in a rock.
