Looking for a new weight loss plan? Try living on top of a mountain. Mountain air contains less oxygen than air at lower altitudes, so breathing it causes the heart to beat faster and the body to burn more energy. A handful of studies have found that athletes training at high altitudes tend to lose weight. Doctor Florian Lippl of the University Hospital Of Ludwig-Maximilians-university Munich wondered how the mountain air would affect overweight individuals if they weren’t doing any more physical activity than usual.
Lippl and his colleagues invited 20 overweight men to an environmental research station about 300 meters below the summit of Zugspitze, a mountain around 2,970 meters near the Austrian border. They were allowed to eat as much as they liked. The men also gave blood so that researchers could test for hormones linked to appetite and fatness. At the end of the week, the men, whose mean weight starting out was 105kg, had lost on average about l.5kg. The men’s blood pressure also dropped, which the researchers believed was due to weight lost.
Exactly what caused the weight loss is uncertain. Loss of appetite is common at higher altitudes, and indeed the men ate significantly less than usual—about 700 calories fewer per day. Lippl also notes that because their consumption was being recorded, they may have been more self-conscious about what they ate. Regardless, eating less accounts for just l kg of the l.5 kg lost, says Lippl. He thinks the increased metabolic (新陳代謝的) rate, which was measured, also contributed to weight loss but cannot separate the different effects with the given data.
Appetite loss at high altitudes could certainly be key, notes Damian Bailey, a physiologist at the University of Glamorgan, UK, who recently lost 11 kg during a 3-month expedition to the Andes in Chile.   
Unfortunately, for the average person there is no treatment that can resemble living at high altitude, says Lippl. The only alternative is hypobaric chamber, which exposes subjects to low oxygen and isn’t practical as a treatment. He says, half- jokingly, “If fat people plan their holidays, they might not go to the sea, but maybe to the mountain.”
小題1:What contributes the most to one’s heart rates according to the first paragraph?
A.our bodyweightB.the consumption of energy
C.the rates of our breathingD.the amount of oxygen provided

A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.
They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.
While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”

When you practice reading with passages shorter than book length, do not try to take in each word separately, one after the other. It is much more difficult to grasp the broad theme of the passage this way, and you will also get the stuck on individual words which may not be absolutely essential to a general understanding of the passage. It is a good idea to skim through the passage very quickly first to get the general idea of each paragraph. Titles, paragraph headings and emphasized word can be a great help in getting this skeleton outline of the passage. It is surprising how many people do not read titles, introductions or paragraph headings. Can you, without looking back, remember the title of this passage and the heading of this paragraph?
Most paragraphs of a passage or chapter have a 'topic sentence' which expresses the central idea. The remaining sentence expand or support that idea. It has been estimated that between 60% and 90% of all expositive(說明的)paragraphs in English have the topic sentence first. Always pay special attention to the first sentence of a paragraph; it is most likely to give you the main idea.
Sometimes , though , the first sentence in the paragraph does not have the feel of 'main idea' sentence. It does not seem to give us enough new information to justify a paragraph. The next most likely place to look for the topic sentence is the last sentence of the paragraph.
Remember that the opening and closing paragraphs of a passage or chapter are particularly important . The opening paragraph suggests the general direction and content of the piece, while the closing paragraph often summarizes the very essence (精髓).
小題1:It is a good idea to skim through a passage quickly first ________.
A.a(chǎn)t about 350 w. P.m.(words per minute)
B.to get the general idea of each paragraph
C.so that you can take in each word separately
D.to make sure you get to the end at least once
小題2:The topic sentence of an expository paragraph in English_______.
A.usually comes in the middle
B.is most likely to be found at the end
C.is most often at the beginning
D.is usually left out in expository writing
小題3:Most expository paragraphs in English have a clearly defined topic sentence. In such paragraphs the topic sentence comes first ________.
A.in about 40% of casesB.in about 80% of cases
C.in about 20% casesD.very rarely
小題4:Some times we know the first sentence is not the topic sentence because ________.
A.it does not seem to give us enough new information
B.it is not long enough
C.it does not come at the beginning
D.it does not make complete sentence

Imagine when you are sailing an ocean for the first time, you see a big fish swimming near your ship. You might be scared, and worried about whether it will turn over your ship for a meal. In fact, it is not a fish at all, but a gentle giant whale.
Whales are not fishes but mammals (哺乳動(dòng)物). Their body temperature stays the same, and does not change with the temperature of their environment. They breathe air, so they have to come out of the water to get oxygen. Thus, they cannot afford to fall into a sleeping state for too long, since they need to be awake in order to breathe. It is thought that only half of their brains sleep at a time, so that whales are never completely asleep. Females give birth to the young. They have hair. Although they are not covered in hair or fur like many mammals, whales have some bristles (胡子), usually on their heads.
Whales are highly social animals with complex languages and intelligence. They communicate with each other using romantic sounds, called “whale songs”. Being so large and powerful, these sounds are also loud.
Whales are endangered as a result of whaling (捕鯨) from the eleventh century to the twentieth. It has attracted the attention of environmentalists and some measures (措施) have been taken to protect whales.
小題1:How many aspects show that whales are mammals?
A.One.B.Two.C.Three.D.Four.
小題2:We can infer from the second paragraph that ____.
A.whales can breathe in the water
B.if a whale sleeps too long, it will get drowned
C.in order to breathe, whales never sleep
D.whales give birth to the young on the land
小題3: How do whales communicate with each other?
A.By body language.B.By speaking languages.
C.By making song-like sounds.D.By giving off a smell.
小題4:Which of the following is TRUE according to the passage?
A.Whales are cold-blooded mammals like fishes.
B.Whales are hunted for food by people.
C.Whales are very harmful to human beings.
D.Whales are in danger because of being killed by people.

The sea horse is a magical animal, which has puzzled (使困惑) people for thousands of years. In ancient Rome sea horses were believed to be the babies of Neptune’s horses. And Neptune was the god of the ocean. Now we know they are not horses at all — they are a kind of fish. They still seem as magical as ever, especially to divers who have watched them horsing around(瞎闖) in the sea. But today, sea horse populations face an uncertain future. Fishermen are catching too many of them, and their undersea habitats (棲息地) are being destroyed.
At least 20 million sea horses are taken from the ocean each year. More than 95% are used for traditional medicines in Asian countries. The sea horses are usually dried and then made into powder which is used to treat such problems as asthma(哮喘), throat infections, skin diseases and cuts. How well the medicines work is unclear.
Sea horses are also bought and sold in large numbers as pets. Sea horse expert Amanda Vincent warns against buying pet sea horses. “A lot of people treat them as if they’re goldfish,” she says. But sea horses require very special care and live food. Most captive (被獵取的) sea horses pick up diseases and die.
Sea horse experts are trying to teach fishermen to become sea horse farmers. Instead of pulling nets of sea horses from the ocean, fishermen could learn to raise them in specially designed saltwater “farms”. That way, fishermen would have sea horses to sell, but ocean populations would not be hurt.
Vincent and her team have only discovered the 35 different species of sea horses, and they still have plenty of sea horse secrets left to unlock. That is why, Vincent told TFK, protecting future sea horse populations is especially important: “I promise your readers that by the time they grow up to be marine biologists, we’ll still have a lot to learn.”
小題1:In the past, Romans thought the sea horse to be ______.
A.a(chǎn) kind of horseB.a(chǎn) kind of fish
C.the god of the ocean D.one of Neptune’s pets
小題2:Which of the following is NOT true according to the passage?
A.People in Asian countries hunt sea horses for food.
B.Most sea horses caught are used as medicine.
C.The effects of the powder of sea horses are uncertain.
D.35 different kinds of sea horses have been discovered.
小題3:The underlined phrase “pick up” in Paragraph 3 probably means “______”.
A.followB.collectC.getD.create
小題4:It can be inferred that the best way to protect sea horses is to ______.
A.do more research on sea horses
B.teach fishermen how to farm sea horses
C.stop hunting sea horses
D.ban the sea horse trade

Have you ever noticed someone "talking" to them-selves? What did you think? The word "crazy" probably came to your mind. Wait a minute, though. Maybe they’re doing something meaningful.
Speaking practice can be effective in many different forms when people learn English or another foreign language. Imitating the speech of others is proven to be highly effective in developing a native speaker’s level of fluency in a language. Actually you’ve already proven that to your-self.
How? That’s how you learned your first language! Whether it was English, Spanish, French or some other language, you "imitated" your mother, father, other family members, friends, teachers and whoever else was around making "talking" noises at you as you formed your first communicative language skills.
So don’t think those who are talking to themselves are "crazy". At least don’t do so until you’ve tried it for your-self, in English or in your new foreign language.
As you go through your day, in English or your new foreign language, tell yourself what you’re doing at the moment and what you’re going to do during the day.
"Which of these shirts, ties, etc. should I wear today? Not this one, I wore it just last week. Maybe this one, but I don’t like this color with the pants. Let’s try another one," you might say as you are getting dressed.
If you live alone, you can talk aloud whenever you want without disturbing others. If you don’t live alone, however, then first explain to your family or roommates what you’ll be doing, to avoid a quiet phone call to the local psychiatrist (精神病學(xué)家).
小題1:The author wrote the passage mainly to _______.
A.tell us how to talk to ourselves
B.introduce a method of learning a foreign language
C.tell us why some people talk to themselves
D.explain to us how we learned our native language
小題2:What does the underlined word "it" in the fifth paragraph refer to?
A.The word "crazy".B.A foreign language.
C.The skill of communicating.D.The method of talking to oneself.
小題3:From the passage we can know that ______.
A.people who talk to themselves are crazy
B.if you live alone, you should talk to yourself
C.you should tell yourself what you’re doing
D.we learned our native language by imitating

Reading is not the only way to gain knowledge of the work in the past. There is another large reservoir (知識(shí)庫(kù)) which may be called experience, and the college students will find that every craftsman (工匠) has something he can teach and will generally teach gladly to any college student who does not look down upon them. The information from them differs from that in textbooks and papers chiefly in that its theoretical (理論的) part -- the explanations of why things happen -- is frequently quite fantastic (神奇的) . But the demonstration (示范) and report of what happens, and how it happens are correct even if the reports are in completely unscientific terms. Presently the college students will learn, in this case also, what to accept and what to reject. One important thing for a college student to remember is that if Aristotle could talk to the fisherman, so can he.
  Another source of knowledge is the vast store of traditional practices handed down from father to son , or mother to daughter, of old country customs ,of folklore (風(fēng)俗). All this is very difficult for a college student to examine, for much knowledge and personal experience is needed here to separate good plants from wild grass.The college students should learn to realize and remember how much of real value science has found in this wide, confused wilderness and how often scientific discoveries of what had existed in this area long age.
小題1: In the last paragraph the phrase "this wide, confused wilderness" refers to _____.
A.personal experience
B.wild weeds among good plants
C.the information from the parents
D.the vast store of traditional practices
小題2: Which of the following statements is supported by the passage?
A.The college students have trouble separating good plants from wild grass
B.Craftsman’s experience is usually unscientific
C.The contemptuous (傲慢的) college students will receive nothing from craftsmen
D.Traditional practices are as important as experience for the college students
小題3: The author advises the college students to ______ .
A.be contemptuous to the craftsman
B.be patient in helping the craftsman with scientific terms
C.learn the craftsman’s experience by judging it carefully
D.gain the craftsman’s experience without rejection
小題4: The main idea of this passage is about ________.
A.what to learn from the parentsB.how to gain knowledge

Just when scientists think they have discovered and recorded every species of insect that crawls the earth they find something new. Earlier this month, Peter Jager, the head of Frankfurt’s Senckenberg Research Institute reported the discovery of a unique eyeless spider.
The creature that has a leg span (跨度) of six centimeters and a body size of just twelve millimeters was found in a cave inside the tiny nation of Laos, in Southeast Asia. It was identified as a member of the Huntsman spider, a large family that consists of 1100 species. However, the other members of the family all have eyes. The spider is the first one that has no eyes. They believe that the kind of spider has adapted to the fact that they do not really need the eyes to such a degree that they have dispensed with them altogether.
But they are not the only creature to have done that. Over the years, scientists have discovered completely blind cave fish, and even a freshwater crab, which happens to live in the same cave as this eyeless spider!
Surrounded by Burma and China on the northwest, Vietnam on the east, Cambodia on the south and Thailand on the west, the landlocked nation of Laos is filled with a large number of new and exotic (新奇的) species. In the last few years researchers have discovered the Saola—never-before-seen antelope-like creature, a small deer species called muntjacs, a tiny stripped rabbit and a rock rat that was thought to have been extinct 11 millions years ago. In addition to that it is also home to over one hundred species of large mammals ranging from tigers to macaques and over 165 species of amphibians (兩棲動(dòng)物) and reptiles like the terrible King cobra and the noisy Tokay gecko, a permanent resident inside most Laos households.
64. 小題1:Which of the following is the best title of passage?
A.Laos full of a large number of exotic species
B.Laos popular with plenty of strange species
C.Every species of insect discovered and recorded by scientists
D.World’s first eyeless spider discovery in Southeast Asia.
