Unit1必修5
一、单项填空
1．It’s ______ good feeling for people to admire the Shanghai World Expo that gives them ______ pleasure.
A．不填；a B．a；不填
C．the；a D．a；the
解析：考查冠词的用法。句意：观赏上海世博会对人们来说是一种不错的感受，它能给他们快乐。feeling是可数名词，因此前面用a表示“一种好的感受”；pleasure常用作不可数名词，故第二个空不用冠词。
答案：B
2．I think it should be I myself not my wife who______for the bad habit of my child in the study before going to school.
A．am to be blamed B．is going to blame
C．am to blame D．should blame
解析：在强调句中考查固定搭配。该句对I myself进行了强调，myself是I的同位语，因此谓语动词应与I保持一致；sb.is to blame for sth.是固定搭配“因某事责备或抱怨某人”，用主动形式表示被动意义，故选A项。句意：我认为应该是我本人而不是我的妻子该为孩子去学校之前的学习的不良习惯受到责备。
答案：C

二、阅读理解
A
Thirsty？You might want to consider a steaming cup of tea.In a survey of existing research published in the European Journal of Clinical Nutrition，the authors report that not only does tea supply the liquid for human bodies and satisfy your thirst as well as water does，it comes with additional health benefits too.
“Drinking tea is actually better for you than drinking water，”Dr.Carrie Ruxton，a nutritionist and the lead author of the study told the BBC.“Water is essentially replacing fluids.Tea replaces fluids and contains antioxidants(抗氧化剂)so it’s got two things going for it.”
Those antioxidants—specifically flavonoids—can reduce damage done to cells through everyday living，so researchers believe these same compounds(化合物)may help to ward_off heart attacks and some types of cancer.
They found clear evidence that drinking three to four cups of tea a day can cut the chances of having a heart attack.Some studies suggested drinking tea protected against cancer，although this effect was less obvious.Other health benefits included protection against tooth diseases，plus bone strengthening.
The researchers also addressed an explanation about tea’s side effects，which make your body lose water.Although some elements can remove water from your system，even a strong cup of tea—for that matter—is introducing more water to your body than it may remove.
The British Nutrition Foundation recommends about 1.5 to 2 liters or about eight and a half cups of liquid a day，and the study showed that one to six tea drinks a day，including black tea，improved antioxidant intake(吸入)．However，there is some evidence that tea can prevent the iron absorption from food，so especially those at risk of anemia(贫血)should avoid a cup of tea near the mealtime.
本文指出了饮茶的好处，饮茶能防止心脏病和癌症的发生，同时指出饮茶的注意事项，因为科学证明，茶能阻止铁元素的吸收而导致贫血。
1．Dr.Carrie Ruxton thinks drinking tea is better than drinking water because ______.
A．drinking tea can satisfy people’s thirst
B．tea makes your body stronger
C．drinking tea is a good habit
D．tea replaces fluids and contains antioxidants
解析：细节理解题。根据文章第二段最后一句“Tea replaces fluids and contains antioxidants so it’s got two things going for it.”可知，饮茶不仅补充了人体体液，而且还含有抗氧化剂，所以Dr.Carrie Ruxton认为喝茶比喝水好。
答案：D
2．The underlined phrase “ward off”in the third paragraph is closest in meaning to ______.
A．cause B．analyze
C．avoid D．cure
解析：词义猜测题。根据文章第四段可知，饮茶可以降低得心脏病的几率，还可以预防癌症。由此可推测ward off为“预防，避免”的含义。
答案：C
3．Which is not the benefit of drinking tea?
A．Drinking tea can reduce the risk of having a heart attack.
B．Drinking tea can help protect people against cancer.
C．Drinking tea can prevent people from getting tooth diseases.
D．Drinking tea can help remove water from human bodies.
4．In which section of a newspaper are you likely to read the article?
A．Health and diet. B．Science.
C．World news. D．Sports news.
解析：文章出处题。文章主要讲述饮茶的好处，以及不要在不当的时候饮茶。是关于健康饮食方面的，故有可能出现在报纸中的健康饮食方面。
答案：A
B
Back when our children were small，who could have imagined what life would hold for them：pressures surrounding sex，alcohol，drugs，and a confusing series of messages，choices，and consequences？Many parents realize that the children’s need for independence grows as they do.So talking about touchy(棘手的)subjects can be especially difficult when teens tend to tune_us_out.
Driving a teen to meet her friends may seem like just another chore，unless you recognize it as an opportunity to talk.Of course，you may have to get the conversation going.Try telling your child a little about your day or talking about her friends before asking her how things are going.If you worry about losing control of the conversation，try to do something you both enjoy together，like cooking，hiking，or going to a concert or museum.Once you have created a comfortable level of sharing，try approaching a touchy subject.
“Before I discuss topics like sex or drugs with my son，”one father says，“I do a little homework.Often it’s as simple as checking the phone book for hotlines or asking my doctor to recommend some books.If my son is not willing to discuss a touchy subject，I can still give him a number to call or an article to read.And，of course，I tell him I’m always available if he needs my help.”
Don’t start a personal attack or hold a family conference to open a dialogue on a tough subject.No matter how serious the subject is，it’s important not to be heavy-handed(粗暴的)or focus on your child too much.
Say you’ve read an article or heard about a troubling situation from a colleague or a friend.Share this information with your teenager；then ask her opinion rather than offer yours.Suppose you’re discussing AIDS，and you can invite your children’s interest by asking：Do you believe it can’t happen to you？What are some strategies to stay safe？When a teen feels that the two of you are exploring a subject together，she’s likely to share her own thoughts.
文章探讨了父母和孩子如何就棘手的话题进行沟通。
5．The underlined phrase“tune us out”in Paragraph 1 can be replaced by“______”．
A．rely much on us
B．get along well with us
C．understand what we say
D．pay no attention to what we say
解析：词义猜测题。根据上文“Many parents realize that the children’s need for independence grows as they do.So talking about touchy subjects can be especially difficult when teens tend to...”可知，许多父母意识到孩子独立性的需要正在增长，所以讨论棘手的话题尤其困难，孩子们不是很在意父母的教导。由此可推知，画线词含义为“不理会 (父母的话)”。
答案：D
6．As for a touchy subject，parents should avoid ______.
A．talking much about their children’s friends
B．sharing information with all family members
C．communicating with their children in a formal way
D．being curious about their children’s opinion
解析：推理判断题。根据第四段“Don’t start a personal attack or hold a family conference to open a dialogue on a tough subject.”可知，不要以个人抨击或是召开家庭会议来公开讨论棘手的话题。再根据最后一段举出讨论AIDS的例子可推知，对于棘手的话题家长应该避免以一种正式方式与孩子进行讨论。
答案：C
7．In the case of discussing AIDS，what parents can do is to ______.
A．remind their children of its danger
B．inspire their children to express their ideas
C．take advice from their colleagues or friends
D．give their children as much advice as possible
解析：细节理解题。根据最后一段“Suppose you’re discussing AIDS，and you can invite your children’s interest by asking：Do you believe it can’t happen to you？What are some strategies to stay safe？”可知，在谈论AIDS时，父母可以通过问问题来鼓励孩子说出自己的想法。
答案：B
8．What’s the purpose of the passage?
A．To explain what touchy subjects children face now.
B．To offer tips on how to discuss touchy subjects with children.
C．To show the influence of touchy subjects on children.
D．To explain why parents should help children solve touchy subjects.
