When we think of Hollywood, we think of films and famous film stars. They are part of Hollywood’s history. Today people make films in other places, too. Not all famous film stars live in Hollywood. But Hollywood is still a very special part in Los Angeles, Cali­fornia.

You can easily see where Hollywood is in Los Angeles. There is a big sign on the hills. It says “HOLLYWOOD”. The white letters are fifty feet tall. You can see the sign from far away. The Holly­wood sign is a famous Hollywood landmark (標(biāo)記) in Los Angeles. Many post­cards show this famous Hollywood land­mark.

In the hills of Hollywood, there is also the Hollywood Bowl. This is an open-air theatre. It is one of the biggest open-air theatres in the world. It has seventeen thousand seats and a very dif­ferent stage (舞臺). The designer (設(shè)計(jì)師) of the stage was a great American called Frank Lloyd Wright. You can listen to different kinds of concerts at the Hollywood Bowl.

1The best title for the article should be “____”.

Can people change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour.

The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.

Scientists have changed the colour of a dark-striped zebrafish to uniform gold by inserting a version of  the pigment(色素) gene into a young fish. As with humans, zebrafish skin colour is determined by pigment cells, which contain melanosomes(黑色素). The number, size and darkness of melanosomes per pigment cell determines skin colour.

It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation(變異) in the gene for melanosome production. This results in less pigmented skin.

However, Keith Cheng, leader of the research team, points out that the mutation is dif ferent in human and zebrafish genes.

Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun(太陽光紫外線), which can cause skin cancer.

But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vit amin D. So the related gene changes, according to Cheng.

Asians have the same version of the gene as Africans, so they pr obably acquired their light skin through the action of some other gene that affects skin colour, said Cheng.

The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like chemical treatment did on Michael Jackson.

 

1.. The passage mainly tells us that ________.

  A. people can not change their skin colour without any pain

  B. the new discovery could lead to search into ways to change skin colour safely

  C. pop king Michael Jackson often changed his skin colour as he liked

  D. scientists have found out that people’s skin colour is determined by the gene

2.. Scientists have done an experiment on  a dark-striped zebra fish in order to ________.

  A. find the  different genes of humans’

  B. prove the humans’ skin colour is determined by the pigment gene

  C. find out the reason why the Africans’ skin colour is dark

  D. find out the ways of changing peopl’s skin colour

3.. The reason why Europeans are light-skinned is probably that ________.

  A. they are born light-skinned people

  B. light-skinned Europeans have mutation in the gene for melanosome production

  C. they have fewer activities outside

  D. they pay much attention to protecting their skin
