without putting on weight, is to be released in British stores. The invention, called the world"s first breathable
food by its creators, lets consumers suck in the taste of chocolate or coffee while taking on less than one
calorie. Its makers claim it will enable dieters to enjoy their favorite snacks without worrying about their
waistline.
The lipstick-style tube contains hundreds of milligrams of tiny food particles which are small enough to
become conveyed by air, but too large to enter the lungs. Each Le Whif contains enough flavor for about
eight to ten whiffs (喷射) and costs 1.99 on its own, or £4.99 for a pack of three. The inhaler is available
in chocolate, raspberry chocolate and mint chocolate models as well as coffee flavor, which gives a dose of
caffeine equivalent to a small short of strong black coffee.
It was invented by Prof. David Edwards. He said Le Whif was not designed to replace food but could be
used to increase dining experiences, such as allowing people to sample a variety of dishes from restaurant
menus before ordering their meal.
He said, "In terms of living off whiffing we aren"t even close to being there. But there clearly has been a
revolution over the last few years where we are eating smaller amounts of food more frequently and choosing
food or its aesthetic (审美的) pleasure. We will be launching new whiffing experiences probably every six
months. It is reasonable to assume that the next line of whiffing products will be even more health centered."
The product was released in Paris in 2009 and the initial production run of 25,000 inhalers were sold out
within a month. It has since been made available across France and in the US. In Britain Le Whif is to be sold
firstly in House of Fraser for a month, after which it could become more widely distributed.

Dolphins and sharks are showing up in surprisingly shallow water just off the Florida coast. Mullets, crabs,
rays and small fish gather by the thousands off an Alabama pier. Birds covered in oil are crawling deep into
marshes (沼泽), never to be seen again.
Marine scientists studying the effects of the BP disaster (英国石油公司漏油事件) are seeing some strange
phenomena. Fish and other wildlife seem to be fleeing the oil out in the Gulf and clustering in cleaner waters
along the coast in a trend that some researchers see as a potentially troubling sign. The animals" presence close
to shore means their usual habitat is badly polluted, and the crowding could result in mass die-offs as fish run
out of oxygen. Also, the animals could easily be captured by their enemies.
The nearly two-month-old spill (漏油) has created an environmental disaster in US history as tens of millions
of gallons have flown into the Gulf of Mexico ecosystem. Scientists are seeing some unusual things as they try
to understand the effects on thousands of species of marine life.
For nearly four hours Monday, a three-person crew with Greenpeace cruised past delicate islands and
mangrove-dotted inlets in Barataria Bay off southern Louisiana. They saw dolphins by the dozen frolicking (嬉
戏) in the oily sheen (光泽) and oil-tinged pelicans feeding their young. But they spotted no dead animals.
"I think part of the reason why we"re not seeing more yet is that the impacts of this crisis are really just
beginning," Greenpeace marine biologist John Hocevar said.
The counting of dead wildlife in the Gulf is more than an academic exercise; the deaths will help determine
how much BP pays in damages.
B. Dolphins and sharks show up in deep water.
C. Tens of thousands of marine animals are found dead.
D. Sea creatures flee from the spilled oil, gathering near the seashore.
B. Many animals could be easily eaten by their enemies.
C. Masses of fishes could die due to lack of oxygen.
D. Some dolphins are frolicking in marshes.
B. the lack of environmental sense of BP
C. the nearly two-month-old oil spill
D. the crowding marine life
B. Disappointed.
C. Depressed.
D. Optimistic.
B. marine scientists have seen some strange phenomena
C. the disaster has little influence on dolphins
D. a three-person crew reached no conclusion
HIV. The tests are the first step in human clinical trials of two vaccine candidates developed at the University
of Cape Town.
These experimental AIDS vaccines are the first from Africa to reach testing in people. The National
Institutes of Health in the United States provided assistance. Testing with twelve people began earlier this year
in Boston, Massachusetts.
South Africa has more than five million people infected with HIV, the largest number of any country.
South Africa launched the tests last week as the International AIDS Society held a conference in Cape
Town. Other human trials of possible vaccines are taking place around the world. Scientists hope to get some
results later this year.
But during last week"s conference, experts reported the first decrease in international financing for AIDS
vaccine research. They said funding dropped from about 930 million dollars in 2007 to 870 million last year.
Also at the conference, scientists presented the latest findings about new mothers infected with HIV. Two
studies showed ways in which anti-HIV drugs could permit infected women to breastfeed their new borns
with less risk of passing the virus to them. The research was done in Cameroon, Ivory Coast, South Africa
and Zambia.
In one study, infected mothers began to take three anti-HIV drugs while breastfeeding for up to six months.
In a second study, the babies were given medicine, instead of their mothers. The babies received one drug
every day during six months of breastfeeding.
The researchers said both methods greatly reduced the risk of HIV infection.
Laura Guay is Vice President of research at the Elizabeth Glaser Pediatric AIDS Foundation, which
supported the research. Doctor Guay says the problem in sub-Saharan Africa is the limited availability of anti-
retroviral drugs.
LAURA GUAY:"We know that only about 33 percent of women have access to a program that actually
has services in place to prevent mother-to-child transmission. So the first challenge is, how do we reach all
the women who do not have access to a prevention program?"
B. the vaccine has been developed in South Africa
C. the United Nations will offer it assistance
D. it has enough volunteers who are AIDS carriers
B. Newborns are easily got infected with HIV if their mothers got AIDS.
C. Anti-HIV drugs help mothers infected with AIDS avoid transmitting HIV to their babies.
D. Both the mother and the newborn can take the anti-HIV drugs.
B. South Africa was the first country which began the test of the vaccines.
C. Anti-HIV drugs have less effect on babies than on their mothers who are affected AIDS.
D. Only those women from rich families have access to anti-HIV drugs.
B. The lack of volunteers.
C. The difficulty in human clinical trials.
D. Too many AIDS patients.

according to a federal government survey released on Tuesday.
On average, 8.5 percent of adolescents aged 12 to 17 described having had a major depressive episode
in the previous year, the Substance Abuse and Mental Health Services Administration reported.
But there were "striking differences" by sex, with 12.7 percent of girls and 4.6 percent of boys affected.
Depression is the leading cause of suicide, which in turn is the third leading cause of death for 15 to 24
year olds in the United States.
"Combined 2004 to 2006 data show that rates of past year major depressive experience among youths
aged 12 to 17 generally increased with increasing age," the researchers wrote.
Researchers at SAMHSA and RTI International in Research Triangle Park, North Carolina, prepared the
report using data from the National Survey on Drug Use and Health.
More than 67,700 youths aged 12 to 17 answered questions about mood and depression. They were also
asked to rate how depression affected them using the Sheehan Disability Scale, which measures impact on
family, friends, chores at home, work and school.
Researchers defined a major depressive episode as two weeks or longer of depressed mood or loss of
interest or pleasure, and at least four other symptoms (症状) such as problems with sleep, energy,
concentration or self-image.
Nearly half of the teenagers who had major depression said it severely damaged their ability to function in
at least one of the areas on the disability scale.
"Fortunately, depression responds very well to early intervention and treatment," SAMHSA Administrator
Terry Cline said in a statement.
B. expression
C. experience
D. experiment
B. poor health, sex discrimination, less energy and loss of interest
C. suicide, sadness,lack of confidence and depression
D. no family or friends or jobs or interests at all
B. There were over 2 million American teens suffering depression in the past two years.
C. The students surveyed were aged between 12 and 17.
D. Depression is the third leading cause of suicide.
B. How to live a comfortable life.
C. How to recover from stress.
D. How to prevent and treat depression.
(生态系统). Unlike other animals, the African elephant is to a great extent the builder of its environment. As a
big plant-eater, it largely shapes the- forest-and-savanna (大草原) surroundings in which it lives, therefore
setting the terms of existence for millions of other animals that live in its habitat.
It is the elephant"s great desire for food that makes it a disturber of the environment and an important builder
of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees
and under-bushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical
forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants
in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight
and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make
open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable
for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant
disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly
changing and worsening the whole ecosystem.
B. Forests and savannas as habitats for African elephants.
C. The effect of African elephants" search for food.

B. They provide food mainly for African elephants.
C. They are home to many endangered animals.
