题目内容

19.It was not until I had read your letter _____ I understood _____ the true state of affairs was.(  )
A.what; thatB.that; whatC.which; whatD.when; which

分析 直到读了你的信,我才真正弄清了事态.

解答 答案:B
本题考查强调句和宾语从句.根据强调句的基本结构"It is/was+被强调成分+that/who+剩余成分"可知,该题中被强调的成分为not until I had read your letter 意为"直到读了你的信",被强调成分所指非人,故应用that引导剩余成分,在剩余成分中 ___ the true state of affairs was为动词understood的宾语从句,表达意思为"真正的事态是什么",故应用what来引导该宾语从句.故选B.

点评 做单选题时,一定要对题干句子结构进行准确分析,这样才能弄清具体考查什么知识点,避免因不清楚结构而选错答案.

11.阅读下面的短文,然后按照要求写一篇150词左右的英语短文.
I believe in the power of the well-written thank-you letters.My sister and I were taught at a very early age to write thank-you letters for birthday and Christmas gifts.We carefully copied addresses from our mom's address book into our own pretty little books.We wrote our letters on December 26th at the latest every year.It was an important activity in our home,and it has turned me into an eager thank-you-letter writer as an adult.Nearly every Monday morning I sit down with my favorite pen and write a few thank-you letters.I write them for parties I attend,dinners I'm fed,or just to thank a friend for listening.Several years ago I even sent my mom a thank-you letter to thank her for teaching me to count my blessings on paper.
Sending letters of thanks out into the world has made me more appreciative of the love,support,and kindness I receive daily.I am more motivated to do kind things for others when I feel appreciated,and I feel that I keep kindness and generosity living by genuinely expressing my thanks.

4.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 99percent of Europeans.The other is found in 93to 100percent 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(斑马鱼) 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 melanin (黑色素).The number,size and darkness of melanin per pigment cell determine skin color.
It appears that,like the golden zebra-fish,light-skinned Europeans also have a mutation (变异) in the gene for melanin 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 1.5million 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.

57.It can be inferred from the passage thatC.
A.the new discovery couldn't help to find medical treatments for skin cancer.
B.Europeans and Africans have the same gene.
C.nowadays people who want to change their skin color have to suffer a lot from the damage caused by the chemical treatment.
D.there are two kinds of genes.
58.Scientists have done an experiment on a dark-striped zebra-fish in order toA.
A.prove the humans'skin color is determined by the pigment gene.
B.find the different genes of humans'.
C.find out the reason why the Africans'skin color is dark.
D.find out the ways of changing people's skin color.
59.The reason why Europeans are light-skinned is probably thatB.
A.they are born light-skinned people.
B.light-skinned Europeans have mutation in the gene for melanin production.
C.they have fewer activities outside.
D.they pay much attention to protecting their skin.
60.The passage mainly tells us thatD.
A.people can not change their skin color without any pain.
B.the new discovery could lead to research 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.
