Some people have very good memory(记忆力) and they can easily remember quite long texts. There are other people who can only remember things when they have said them again and again. The famous English writer Charles Dickens said that he could walk down any long street in London and then tell you the name of every shop he had passed. Many great men of the world have a wonderful memory.
A good memory is greatly helpful in learning a language. Everybody learns his own language by remembering what he hears when he is a small child, and some children, like the boys and girls who live abroad(国外) with their parents, seem to learn two languages almost as easily as one. In school it is not so easy to learn a second language because the students have so little time for it, and they are very busy with other subjects too.
A man’s mind is like a camera, but it takes photos not only of what we see but also of what we feel, hear, smell and taste. When we take a real photo with a camera, Some people have very good memory(记忆力) and they can easily remember quite long texts.In the same way, there is much work to be done before we can keep a picture forever(永远) in our minds.
Memory is a diary, and we all carry it about us. We keep things we have experienced (经历)in this diary.

A.you can learn a second language easily |
B.you can remember things for ever easily |
C.you can learn your own language easily |
D.you can remember things better |
A.We all keep a diary in our mind. |
B.One has to do a lot of work before he can keep a picture in his mind forever. |

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(变异) 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 different 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(太阳光紫外线), 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 vitamin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they probably 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.
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
It can be inferred from the passage that ________.
A. nowadays people who want to change their skin colour have to suffer a lot from the damage caused by the chemical treatment
B. Europeans and Africans have the same gene
C. the new discovery could help to find medical treatments for skin cancer
D. there are two kinds of genes
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
The writer’s attitude towards the discovery is ________.
A. neutral B. negative C. positive D. indifferent
