Many of us have wondered what Earth is like beneath the surface. So have writers and scientists. In French novelist Jules Verne’s masterpiece Journey to the Center of the Earth, explorers go down to Earth’s center and discover amazing wonders.

But in real life, human beings haven’t even come close to the planet’s core (核心). The core is over 6,000 km down. The deepest hole ever created, according to the BBC, is the Kola Superdeep Borehole in Russia, which only goes 12.3 km down.

So how do we know about everything down below without any samples？

One good way to start is to think about the Earth’s density (密度), Simon Redfern of the University of Cambridge in the UK told the BBC.

“The density of the material on Earth’s surface is much lower than the average density of the whole Earth, so that tells us there’s something that has greater density,” Redfern said.

The challenge is to find out which heavy materials the core is made of. And the main material scientists have found is iron. The idea is that when Earth formed 4.5 billion years ago, a lot of iron made its way down to the core, taking up about 80 percent of it. Today scientists are still working on finding out which other materials the core could be made up of.

You might also wonder how we know the size of the core. There’s a one-word answer: seismology (地震学).

When an earthquake happens, seismic stations around the world record the shockwaves it sends throughout the planet. It’s like hitting one side of the planet with a huge hammer and listening on the other side for the noise.

Early research found that some shockwaves, called “S-waves”, went missing. S-waves can only travel through solid material, but not through liquid, so they must have found something molten in Earth’s center. By following the S-waves’ paths, scientists found out that rocks became liquid around 3,000 km down.

There are still many questions about the Earth’s core to answer. But the study of the dark world below isn’t just for scientists’ curiosity.

The movement of Earth’s molten iron core builds up a powerful magnetic (有磁力的) field. It protects us from radiation from the sun and is needed for compasses and GPS systems to work.

So perhaps none of us will ever set eyes on the core, but it’s good to know it’s there.

1.The author mentions Jules Verne’s novel Journey to the Center of the Earth in the first paragraph to　　　　　　　　 .

A. discuss the possibility of going down to Earth’s center

A. are often used to predict earthquakes

B. cannot travel through liquid material

C. are the most noticeable shockwaves produced by earthquakes

D. can travel most rapidly at 3,000 kilometers below Earth’s surface

3.We can infer from the last three paragraphs that 　　　　　　　　　　　 .

B. improvements in GPS systems could help people find out more about Earth

C. Earth’s core helps to protect humans from harm

For almost 500 years, people have wondered what deadly disease wiped out most of the Aztecs (阿芝特克人）. The locals called it cocolizthi, and now a team of scientists think they know exactly what that was. The outbreak is considered to be one of the deadliest epidemics (传染病）in human history. For centuries, its cause has been debated by historians. New evidence suggests that the Aztecs died from a type of bacteria called salmonella enterica.

An international team of scientists came to this conclusion after analysing the skeletons (骨骼) of 29 Aztecs buried in a cocoliztli cemetery in the Oaxaca region of Mexico. The scientists obtained samples from the teeth of ten of the skeletons. They compared these with their database of bacteria and found traces of salmonella enterica.

Salmonella enterica can cause enteric fever, of which typhoid (伤寒）is a type. Today, there are around 21 million cases of typhoid worldwide and it is considered a global threat.

The Aztecs were fierce hunter-gatherers who settled in what is now Mexico at the beginning of the 13th century. From their incredible capital city Tenochtitlan(now Mexico City),the Aztecs fought wars with other tribes until they ruled much of the region.

The Aztecs ended up controlling large parts of Mesoamerica--now much of Mexico and Central America--until Spanish explorers arrived in 1519 and brought with them advanced weapons and deadly diseases. The team believe that the domesticated animals, such as goats and horses, which the explorers brought with them carried the deadly bacteria.

By 1545,not even 30 years after the Spanish had arrived, Mexico's Aztec nation started coming down with a terrible illness. Symptoms included high fever, headaches and bleeding from the eyes, nose and mouth. Within five years, up to 15 million people---more than 80%of the population at the time--had died from the mystery illness they called cocoliztli. The Aztec people had no immunity (免疫) to fight the disease.

“We cannot say with certainty that salmonella enterica was the cause of the cocolizti epidemic,” said Kirsten Bos from the Max Planck Institute for the Science of Human History in Germany.” We do believe that it should be considered a strong candidate."

1.Which helped the scientists come to the conclusion.

A.Certain traces of deadly diseases carried by goats and horses

B.Extensive comparison of Aztecs buried in a cocoliztli cemetery

C.Definite discoveries of infected tooth samples from the database

D.Small amounts of certain bacteria in the teeth of the skeletons

2.Which of the following is TRUE about the Aztecs?

A.They had a population of about 15 million around 1545.

B.Their livelihood depended on raising domesticated animals.

C.Their population dropped sharply in the middle 16th century.

D.They won the wars with the Spanish despite being poorly equipped.

3.The underlined word “it” in the last paragraph refers to_　　　

A.cocolizti epidemic B.salmonella enterica C.the typhoid D.the Max Planck Institute

4.The passage is mainly about

A.how the Aztecs got infected with salmonella enterica

B.why the Aztecs had no immunity to fight typhoid

C.which reason caused the Aztecs to abandon their native land

D.what led to the military and economic decline of the Aztecs
