Fat and shy, Ben Saunders was the last kid in his class picked for any sports team. "Football, tennis, cricket — anything with a round ball, I was useless," he says now with a laugh. But back then he was the one always made fun of in school gym classes in Devonshire, England.

It was a mountain bike he received for his 15th birthday that changed him. At first he went hiking alone in a nearby forest. Then he began to ride the bike along with a runner friend. Gradually, Saunders set his mind on building up his body, increasing his speed and strength. At the age of 18, he ran his first marathon.

The following year, he met John Ridgway and was hired as an instructor at Ridgwhy’s School of Adventure in Scotland, where he learned about Ridgway's cold-water exploits. Greatly interested, Saunders read, all he could about North Pole explorers and adventures, then decided that this would be his future.

In 2001, after becoming a skillful skier, Saunders started his first long-distance expedition (探险) towards the North Pole. It took unbelievable energy. He suffered frostbite (冻疮), ran into a polar bear land pushed his body to the limit, pulling his supply-loaded sled (雪橇) up and over rocky ice.

Saunders has become the youngest person to ski alone to the North Pole, and he's skied more of the North Pole by himself than any other British man. His old playmates would not believe the change.

Cooking Kills Four Million People a Year

Polluted airborne particles(大气悬浮颗粒)kill 7 million people a year,reports the World Health Organization.

That news may not come as a surprise to anyone who has seen images of chimneys in Beijing,Delhi or Mexico.But those factories—or even the jammed roadways of modern cities—are not the biggest killer.Each year,4.3 million people die earlier than they should because of polluted air inside their homes,says the WHO.

What’s causing the air inside people’s homes to be so poisonous that it kills around 11,000 people a day?Stoves.“Having an open fire in your kitchen is like burning 400 cigarettes an hour.” says Kirk Smith,a professor at the University of California at Berkeley,whose research suggests that household air pollution from cooking killed between 3.5 million and 4 million people in 2013.

Not all stoves cause this kind of harm.The ones Smith’s talking about are those that the 3 billion people in the developing world use for heat and cooking,which burn solid fuels such as wood,coal,or crop waste instead of gas.The smoke from those fires produces harmful fine particles and carbon monoxide into homes.Poor ventilation then prevents that smoke from escaping,raising fine particle levels 100 times higher than the limits that the WHO considers acceptable.

Breathing this air eventually causes a lot of diseases:more than a third of the 4.3 million die of a stroke,while a quarter die of heart disease.And around one-third of annual lung disease deaths worldwide are due to waste from coal stoves.

Exposure tends to be extremely harmful for the people who spend the most time around the fire—usually women and young children.In fact,the WHO reports that household air pollution almost doubles the risk for childhood lung disease.

1.According to Kirk Smith’s research, .

A.factories are the biggest killer worldwide nowadays

B.burning 400 cigarettes an hour is extremely dangerous

C.household air pollution from cooking is surprisingly harmful

D.4.3 million people die earlier each year than they should

2.What should be the deadly killer in a household kitchen?

A.Solid fuels. B.Coal stoves.

C.Poor gas. D.Cooking smoke.

3.The underlined word “ventilation” in Paragraph 4 probably means .

A.airing B.cooking

C.burning D.cooling

4.The author intends to tell people .

A.how to avoid polluted air in their homes

B.to stop cooking in the household kitchen

C.to guard against household pollution from cooking

D.how to prevent childhood lung diseases in household

Have you ever heard a news reporter talk about DNA?Reporters talk about DNA found at the scene of a crime.They talk about police finding DNA “fingerprints”.Police sometimes use DNA as a clue to find out who committed the crime.

DNA is a substance(物质)that makes up genes.Everything alive has genes.Plants have genes.Animals have genes.You have genes.

Genes are the basic units of heredity(遗传).Heredity means all the characteristics you inherit from your parents.You get your genes from your parents.You inherit half of your genes from your mother.You inherit half of your genes from your father.

Genes are a kind of code.A tree’s genes tell what shape its leaves will be.A cat’s genes tell what color its fur will be.Your genes tell what color your eyes will be.Your genes tell what color your hair will be.Everything about you comes from the code in your genes.

Genes line up on strands(链)called chromosomes(染色体)in cells.Everything alive is made up of cells.Chromosomes are in the center,or nucleus of cells.

Different parts of you are made of different kinds of cells.Your muscles are made of muscle cells.Your skin is made of skin cells.The code in your genes tells your body to make different kinds of cells.The genes in each cell tell the cell how to work.They tell the cell when to make new copies of itself.

An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants.He experimented with pea plants in the 1860s.One of the things,or traits(特质) Mendel studied was what makes some pea plants tall and some short.He said that the traits must come from units of heredity passed from the parent plants.These units were later called genes.

In the mid-1900s,scientists discovered that genes are made of DNA.In the 1970s,scientists learned how to change DNA with genetic engineering.Scientists also learned that problems with certain genes cause diseases.Muscular dystrophy,cystic fibrosis,and hemophilia are some genetic diseases—diseases caused by problems in genes.Today,scientists are looking for ways to cure genetic diseases by changing genes through a process called gene therapy.
