Can people change their skin color without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color.
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 color of a dark-striped zebra fish to uniform gold by inserting a version of the pigment(色素) gene into a young fish. As with humans, zebra fish skin color is determined by pigment cells, which contain melanosomes(黑色素). The number, size and darkness of melanosomes per pigment cell determines skin color.
It appears that, like the golden zebra fish, 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 zebra fish 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 color, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color without damaging it like chemical treatment did on Michael Jackson.
64. The passage mainly tells us that ________.
A. people can not change their skin color without any pain
B. the new discovery could lead to search into ways to change skin color safely
C. pop king Michael Jackson often changed his skin color as he liked
D. scientists have found out that people’s skin color is determined by the gene
65. It can be inferred from the passage that ________.
A. nowadays people who want to change their skin color 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
66. 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 color is determined by the pigment gene
C. find out the reason why the Africans’ skin color is dark
D. find out the ways of changing people’s skin color
67. 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 gen for melanosome production
C. they have fewer activities outside
D. they pay much attention to protecting their skin

请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入恰当的单词。
注意:每个空格只填一个单词。
If you are asked to chair a meeting, remember the following six golden rules for meeting management.
1. Always start the meeting on time If you begin on time, group members who show up late will realize the value of time. Beginning on time reflects the skill as an effective time manager and sets an example for others to follow.
2. Select a note-taker or arrange to have the meeting audio-taped You may need to refer back to an issue that was discussed during the meeting at a later date. Good record-keeping is a sign of a good meeting manager as well.
3. Learn to listen So many times we think we are going to say and, in the process, block out important points that other group members may be contributing. Additionally, we often hear only what we want to hear, rather than really listen to other people. Meetings that are characterized by effective listening are successful meetings.
4. Keep the discussion on track Many times important issues can get sidetracked in a meeting, especially when everyone has a different opinion about the topic. If an unexpected conflict develops once the meeting is in progress, either appoint a subcommittee to look into the problem, or ask the participants involved in the conflict to meet with you after the meeting. Doing so will help keep the discussion on track and minimize (减少) the chances of wasting participants’ time of great value.
5. Give everyone an opportunity to be heard Some people tend to control meetings, whereas others wait to be asked their opinions. As the leader of the meeting, you need to keep an open mind and make sure everyone feels welcome to contribute and express ideas without criticism.
6. End on time If you said the meeting would last no longer than one hour, make sure the meeting lasts for only one hour. Running late with a meeting makes members late for other appointments, increases the chances that the members will mentally leave the meeting and reduces your reliability as an effective meeting manager.
