Food
Come mealtime,astronauts will have a special dining kitchen.Space food just keeps getting better—and more like food we enjoy here on Earth.In early space missions,astronauts could eat only freezedried food that didn’t require any preparation.But the space station is equipped with water,microwave ovens,and refrigerators,allowing the folks on board to eat more “normal” types of food,including fruit,vegetables,and ice cream!
Sleep
Each crew member has a private room.With no gravity,they’ll need to tie themselves to their beds,or they will float away!That might sound like a strange way to sleep,but astronauts from past space missions report that sleeping in space is actually pretty great!
Exercise
You might not think it,but exercise is even more important on the station than it is on Earth.There is not much gravity in space.Astronauts don’t stand up,sit down or walk in space,so their muscles and bones don’t have to work much—and this muscle and bone loss can be dangerous back on Earth.To fight this,astronauts on the station will exercise on bikes,rowing machines,and other equipment about two hours every day.
Clothing
Astronauts will have to wear special space suits while traveling aboard the U.S.shuttle or Russian rockets.But once they’re safe inside the space station,crew members can wear regular clothing.Of course,a specially designed,pressurized space suit is required for space walks.It has to withstand(经受住) flying pieces and protect the astronauts from dramatic temperature changes.It can range from 120 degrees below Fahrenheit in the shadow of the station to 250 degrees in the hot sun.
Personal Cleanliness
Simple tasks like brushing your teeth can be challenging in a weightless environment.A little water doesn’t flow in a stream—it suspends in a bubble!Astronauts will use a freshwater hose(软管) to take showers,shampoo,and wash off—then a second vacuum hose to suction(吸) off the dirty water.And how do you go to the bathroom in space?With a special “air toilet” that uses flowing air instead of water to dispose of waste.
小题1:The facts about life in space are all mentioned EXCEPT ________.
A.clothing | B.entertainment |
C.sleep | D.exercise |
A.The temperature is quite different in different places in space. |
B.Astronauts must wear special space suits all the time in space. |
C.Astronauts can wear regular clothing for space walks now. |
D.Astronauts wear pressurized space suits just to keep warm. |
A.It can make astronauts feel relaxed in space. |
B.It can help astronauts spend their spare time happily. |
C.Astronauts’ lives are more important in space than on earth. |
D.It can prevent astronauts from causing muscle and bone loss. |
A.Astronauts could eat apples in space in the past. |
B.Astronauts eat only fruit,vegetables and ice cream now. |
C.Fresh food isn’t available to astronauts in space. |
D.Space food is getting better now than before. |
答案
小题1:B
小题2:D
小题3:D
小题4:A
解析
小题1:B
解析 细节理解题。通读全文可知,第三段是关于sleep;第四段是关于exercise;第五段是关于clothing,文章并未提到宇航员的娱乐活动(entertainment),故答案为B项。
小题2:D
解析 推理判断题。第二段第二句指出,太空食物越来越像我们在地球上所吃的食物,接着指出在过去宇航员只能吃冻***食物,但现在能吃水果蔬菜等平常食物。由此判断,太空食物比过去好了。
小题3:D
解析 细节理解题。由第四段第三、四句“...their muscles and bones don’t have to work much—and this muscle and bone loss can be dangerous back on Earth.To fight this...”可知,由于太空无重力,人不用坐立行走,运动的机会极少,容易给人的肌肉及骨头造成危害,因此宇航员必须每天锻炼两小时,由此可知正确答案为D项。
小题4:A
解析 细节理解题。根据文章倒数第二段最后一句“It can range from 120 degrees below Fahrenheit in the shadow of the station to 250 degrees in the hot sun.”可知,太空中不同地方温差是非常大的,故答案为A项。

Reading on the Internet has changed how we use our brains.Facing a lot of texts,video,music and links to other web pages and blogs,our minds have become used to skimming and scanning information.As a result,we have developed sharper skills at making fast decisions,particularly visual ones,Carr wrote.
But now most of us seldom read books or long articles that would help us focus.We are becoming more like librarians—able to find information quickly and see clearly the best nuggets(有价值的资料).That lack of focus hinders(阻碍) our longterm memory,leading many of us to feel distracted,he wrote.
“What we are losing is a whole other set of mental skills,which require not the shifting of our focus but the maintaining of our focus,” Carr said,adding that for centuries books protected our brains from distraction and focused our minds on one topic at a time.
But with devices such as Apple’s iPad becoming common,Carr predicts books also will change.“New forms of reading always require new forms of writing,” he said.Carr has a suggestion for those who feel web surfing has left them incapable of concentration—slow down,turn off the Internet and practice the skills of contemplation(沉思) and reflection.“It is pretty clear from the brain science that if you don’t exercise particular cognitive skills,you are going to lose them,” he said.“If you are constantly distracted,you are not going to think in the same way that you would think if you paid attention.”
小题1:What topic is Nicholas Carr’s new book mainly concentrating on?
A.Whether there is any need for us to surf the Internet. |
B.How the Internet changes our way of thinking. |
C.What we should do when we are surfing the Internet. |
D.Whether our minds are being influenced by the Internet. |
A.Anxious. | B.Relaxed. |
C.Concentrated. | D.Puzzled. |
A.prevents | B.causes |
C.protects | D.sharpens |
A.They should read more books besides surfing the Internet. |
B.They should often slow down their pace of modern living. |
C.They should often get away from the disturbing of the Internet. |
D.They should spend more time thinking while surfing the Internet. |
As a reviewer,you bring together the two strands of accurate,analytical reading and strong,personal response when you indicate(指出) what the book is about and what it might mean to a reader(by explaining what it meant to you).In other words,reviewers answer not only the WHAT but the SO WHAT question about a book.Thus,in writing a review,you combine the skills of describing what is on the page,analyzing how the book tried to achieve its purpose,and expressing your own reactions.
Most book reviews start with a heading that includes all the basic information about the book,like:
Title.
Author.
Place of publication,publisher,date of publication.
Number of pages.
Like most pieces of writing,the review usually begins with an introduction that lets your readers know what the review will say.The first paragraph usually includes the author and title again,so your readers don’t have to look up to find this information.You should also include a very brief description of the contents of the book,the purpose or audience for the book,and your reaction and evaluation.
Then you move into a section of background information that helps place the book in context and discusses how to judge the book.Next,you should give a summary of the main points,quoting(引用) and explaining key phrases from the author.Finally,you get to the heart of your review—your evaluation of the book.In this section,you might discuss some of the following issues:
•How well the book has achieved its goal.
•What possibilities are suggested by the book.
•What the book has left out.
•How the book compares with others on the subject.
•What specific points are not convincing.
•What personal experiences you’ve had related to the subject.
It is important to use labels to carefully distinguish your views from the author’s,so that you don’t confuse your readers.
Then,like other essays,you can end with a direct comment on the book,and tie together issues raised in the review in a conclusion.
There is,of course,no set form,but a general rule is that the first onehalf to twothirds of the review should summarize the author’s main ideas and at least onethird should evaluate the book.

Seacamp’s tropical marine location in the lower Florida Keys enables it to offer a truly unique marine science program.This program is the heart of Seacamp.Young scientists participate in a variety of courses under the guidance of academically trained marine science instructors and biologists.All science activities include studies in both the field and the laboratory.Each session,140 to 160 campers come to Seacamp,mostly from the US,but also from across the world.There are about 30 international campers each summer from an average of twelve countries.Many Seacamp program graduates have gone on to careers as environmental educators and marine scientists.
One of Seacamp’s unique aspects is that campers create their schedules.In addition to science classes,campers choose from a variety of programs to ensure that there is something interesting and exciting for everyone.Campers interested in journalism may work on the camp newspaper,SEASCOPE,which is published periodically during camp sessions.Arts activities are also included.Photography allows campers to take home memories of friends,wildlife,and underwater experiences.
Seacamp teaches the fun and skills of sailing.It’s an excellent way for future marine scientists to become familiar with the winds,tides and currents that are of primary concern in oceanography.Basic Red Cross certification is offered to beginners in sailing.The Red Cross course in advanced lifesaving is taught at Seacamp.The course is designed to increase the campers’ ability to recognize and avoid dangerous water conditions and practices and to use selfrescue skills to get out of dangerous situations.
Parents may bring campers by car to Big Pine Key.Counselors(辅导员) also meet participants at the Miami International Airport on the opening day of camp and accompany them to Big Pine Key on a bus.The fee for roundtrip service is $90.To join the Seacamp adventure,interested campers should contact Seacamp for an application.
We love to talk about camp!For more information or to ask any questions you might have,please give our friendly staff a call and we’ll be glad to help!

We usually give credit of the taste to our tongue,but do you know that unless saliva(唾液) dissolves something,our tongue cannot recognize the taste of the food eaten.Taste is nothing but the food chemicals dissolved in the saliva being sensed by the taste buds present on the tongue.Try_to_dry_off_your_tongue_and_mouth_with_a_tissue_paper_and_then_taste_something.
Women are much better smellers than men.They are born with this characteristic ability and can correctly pinpoint the exact fragrance of the sample.We all can store almost 50,000 different scents(气味),which are strongly tied to the memories.
Pupils(瞳孔) do not respond to light alone,but to the slightest bit of noise around too.Thus surgeons,watchmakers and those professionals who have to perform a much delicate job do prefer to have a soundfree environment.Even a small noise can dilate(扩大) their pupils,change the focus and blur(使模糊) their vision.If you do not wear glasses or contact lens due to having a 6/6 vision,you are just among the one third of the human population.It is now statistically proved that only one third of the population has perfect vision,rest all are either wearing glasses or are trying to read with a compromised vision.
Each and every one of us has a particular or individualistic or characteristic smell,which is unique to us,except for the identical twins.This smell is very subtle(微妙的) yet can be sensed even by a newborn.It may be due to this scent that the newborn recognizes the presence of his parents around.Many of us can pinpoint the smell of our significant friends and colleagues.A significant part of this phenomenon is guided by genetics but it is also modified by the environment,diet and personal hygiene.This all together creates the unique chemistry that is individualistic for each person.

A.Our tongues can’t be dried while eating something. |
B.If your tongue is dried without any saliva on it,it will not work. |
C.A tissue paper is the only thing that can be used to dry our tongues. |
D.If your tongue is dried with a tissue paper,it may work as well as before. |
There are now more than a thousand genetic(基因的) tests,for everything from baldness to breast cancer,and the list is growing.Question is,do you really want to know what might eventually kill you?For instance,Nobel Prizewinning scientist James Watson,one of the first people to map their entire genetic makeup,is said to have asked not to be told if he were at a higher risk for Alzheimer’s(老年痴呆症).
“If I tell you that you have an increased risk of getting a terrible disease,that could weigh on your mind and make you anxious,through which you see the rest of your life as you wait for that disease to hit you.It could really mess you up.” said Dr.Robert Green,a Harvard geneticist.
“Every ache and pain,” Smith suggested,could be understood as “the beginning of the end.”“That’s right.If you ever worried you were at risk for Alzheimer’s disease,then every time you can’t find your car in the parking lot,you think the disease has started.”
Dr.Green has been thinking about this issue for years.He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s.It was thought that people who got bad news would,for lack of a better medical term,freak_out.But Green and his team found that there was “no significant difference” between how people handled good news and possibly the worst news of their lives.In fact,most people think they can handle it.People who ask for the information usually can handle the information,good or bad,said Green.
小题1:The first paragraph is meant to________.
A.ask some questions |
B.introduce the topic |
C.satisfy readers’ curiosity |
D.describe an academic fact |
A.He is strongly in favor of the present genetic tests. |
B.He is more likely to suffer from Alzheimer’s disease. |
C.He believes genetic mapping can help cure any disease. |
D.He doesn’t want to know his chance of getting a disease. |
A.advisable not to let him know |
B.impossible to hide his disease |
C.better to inform him immediately |
D.necessary to remove his anxiety |
A.break down | B.drop out |
