Why did humans evolve to walk upright? Perhaps because it’s just plain easier. Make that “energetically less costly”, scientifically speaking.

Bipedalism—walking on two feet, is one of the defining characteristics of being humans, and scientists have debated for years how it came about. In the latest attempt to find an explanation, researchers trained five chimps(黑猩猩)to walk on a treadmill(跑步機(jī))while wearing masks that allowed measurement of their oxygen consumption. The chimps were measured both while walking upright and while moving on their legs and knuckles(膝關(guān)節(jié)).That measurement of the energy needed to move around was compared with similar tests on humans and the results are published in this week’s online edition of “Proceedings of the National Academy of Sciences”.

It turns out that humans walking on two legs use only one-quarter of the energy that chimps use while knucklewalking on four limbs(肢).And the chimps, on average, use as much energy using two legs as they did when they used all four limbs.

However, there were differences among chimps in how much energy they used, and this difference corresponded to their different manner of walking and anatomy(解剖構(gòu)造).One of the chimps used less energy on two legs, one used about the same and the others used more, said David Raichlen, assistant professor of anthropology at the University of Arizona.

“What we were surprised at was the variation(變異) ”, he said in a telephone interview. Interview. “That was pretty exciting, because when you talk about how evolution works, variation is the bottom line, without variation there is no evolution.”

Walking on two legs freed our arms, opening the door to drive the world, said Raichlen. “We think about the evolution of bipedalism as one of first events that led hominids(原始人)down the path to being humans.”

The research was supported by the National Science Foundation and the L.S.B.Leakey Foundation.

The underlined word “Bipedalism” in Paragraph 2 probably means____.

A．moving sideways              B．walking upright

C．walking on four legs            D．running fast

We can infer from the passage that____.

A．scientists have no idea on how humans’ walking on two legs came about

B．scientists have had different views on why chimps walk on four legs

C．scientists have had different views on how humans’ walking on two legs vame about

D．scientists have had similar views on how humans’ walking on two legs came about

What is Paragraph 4 mainly about?

A．How chimps saved energy.

B．Why chimps didn't walk on two legs.

C．David Raichlen studied chimps.

D．Different chimps consumed different energy.

According to the passage, humans walk upright in order to____.

A．conserve energy                  B．differ from other animals

C．free their brains                  D．strengthen their legs

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover，these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns，potentially causing certain natural disasters all over the world.
In the past hundred years，humans have begun destroying rainforests in search of three major resources（資源）：land for crops，wood for paper and other products，land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide（二氧化碳）in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.There are two main reasons for this. Firstly，when people cut down trees，generally they can only use the land for a year or two. Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world’s wood supply.
Rainforests are often called the world’s drug store. More than 25％ of the medicines we use today come from plants in rainforests. However，fewer than l％of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.
