Question

The Sleep Research Center at the University of Surrey found a direct link_______the time of sleeping and genes （基因). Each cell （細(xì)胞) in our bodies _____some information in our DNA that acts as a kind of operating instruction. ______, each cell only reads a part of the instruction it needs. Professor DerkJan Dijk asked,“Can ______affect how a gene reads instructions?” He carried out an experiment and asked his ______to spend a week sleeping around seven hours to eight hours a night. And then the next week he______them to sleep six to seven hours a night.

Blood samples were taken each week to compare______genes were in blood cells. They were being used during the long and ______nights.

It is clear that changing the time of sleeping can______our genes, which influence our health. And we may fall______more easily when we sleep less. The important message is that getting sleep about eight hours a night can make an exciting _____to our health in just a few days. It is in this way that it_______our genes. So stop staying up late to listen to______broadcast, read one more chapter, have one more drink or do a little bit more work.______you don’t think it will make some differences, you will regret.

2. 考查介詞詞義辨析。句意為：薩里大學(xué)的睡眠研究中心發(fā)現(xiàn)，睡眠時(shí)間與基因之間有直接聯(lián)系。between 兩者之間；around （在三者及三者以上）之間；in在……里面；under在……下面。分析語(yǔ)境可知，空格處指“兩者之間”。故選A。

3. 考查動(dòng)詞詞義辨析。句意為：我們身體的每個(gè)細(xì)胞________我們DNA的信息，這些信息充當(dāng)操作指令的角色。hurts 傷害；makes制造；carries攜帶；goes去。根據(jù)語(yǔ)境可知空格處意指“攜帶信息”。故選C。

4. 考查副詞詞義辨析。句意為：________，每個(gè)細(xì)胞只讀取它需要指令的一部分。However然而；Especially尤其是；Luckily幸運(yùn)地；Quietly安靜地。聯(lián)系上句“Each cell（細(xì)胞） in our bodies 3 some information in our DNA that acts as a kind of operating instruction.”可知，本句與上句之間是轉(zhuǎn)折關(guān)系。因此“However”用在這里符合語(yǔ)境，指每個(gè)細(xì)胞自身具有缺陷性。故選A。

5. 考查名詞詞義辨析。句意為：________會(huì)影響基因如何讀取指令嗎？ study學(xué)習(xí)；play玩耍；sleep 睡眠；sing唱歌。從上文“The Sleep Research Center at the University of Surrey found a direct link between the time of sleeping and genes.”可知選C。

6. 考查名詞詞義辨析。句意為：他做了一個(gè)實(shí)驗(yàn)，讓他的________一周每晚睡七到八個(gè)小時(shí)。workers工人們；volunteers志愿者們；doctors醫(yī)生們； students學(xué)生們。這里描述的是教授做實(shí)驗(yàn)的方法，實(shí)驗(yàn)主體應(yīng)該是參與實(shí)驗(yàn)的志愿者們。故選B。

7. 考查動(dòng)詞詞義辨析。句意為：然后下一周，他________他們每晚睡六到七個(gè)小時(shí)。asked問(wèn)，要求；stopped阻止；prepared準(zhǔn)備；enjoyed享受。聯(lián)系上句，教授先讓志愿者每晚睡七到八個(gè)小時(shí)，第二周再讓他們每晚睡六到七個(gè)小時(shí)。故選A。

8. 考查疑問(wèn)詞詞義辨析。句意為：每周抽取血液樣本對(duì)比________基因在血細(xì)胞中。what 什么；which哪些；how怎樣；why為什么。分析語(yǔ)境可知指“哪些”。故選B。

9. 考查形容詞詞義辨析。句意為：它們?cè)诼�長(zhǎng)而________黑夜中被使用。 small小的；dark黑暗的； short短的；brave勇敢的。根據(jù)語(yǔ)境可知指“在漫長(zhǎng)而黑暗的夜里”。故選B。

10. 考查動(dòng)詞詞義辨析。句意為：很明顯，改變睡眠時(shí)間可以________我們的基因，影響我們的健康。eat吃掉；change 改變；bring帶來(lái)；sell出售。從“which influence our health”可知，改變睡眠時(shí)間可以改變我們的基因，從而影響我們的健康。故選B。

11. 考查形容詞詞義辨析。句意為：當(dāng)我們睡得少的時(shí)候，我們可能更容易________。ill生病的；smart 聰明的；sad難過(guò)的；shy害羞的。聯(lián)系上文及常識(shí)可知，熬夜或睡眠不足對(duì)身體有害，因此人就容易生病。故選A。
