AIDS-related illnesses have killed more than 30 million people since 1981. That's half as many deaths as in World War II. And it's not over. An estimated 1.1 million Americans are among the 33 million people worldwide who are now living with HIV, the virus that causes AIDS.
Between 1884 and 1924, somewhere near modern-day Kinshasa in West Central Africa, a hunter kills a chimpanzee. Some of the animal's blood enters the hunter's body, possibly through an open wound. The blood carries a virus harmless to the chimp but deadly to humans: HIV.
In June, 1981, the CDC publishes a report from Los Angeles of five young homosexual men with fatal or life-threatening PCP pneumonia. First cases recognized. In 1985, Rock Hudson dies of AIDS. Larry Kramer's AIDS play, "The Normal Heart." shocks New York audiences.
In 1986, for the first time, President Reagan publicly utters the word "AIDS." In 1987, Princess Diana is photographed hugging people with AIDS. Reagan makes his first speech on AIDS. Liberace dies of AIDS. Three years later, Photographer Robert Mapplethorpe dies of AIDS.
In 1988, the first World AIDS DAY is held on Dec. 1. During 1991-1992, the red ribbon is introduced as a symbol of AIDS solidarity(团结一致). But AIDS becomes the leading cause of death in U.S. men aged 25-44 and ten years later, AIDS becomes the leading cause of death worldwide for people aged 15 to 59.
In 2008, for the first time, global AIDS deaths decline. UNAIDS calculates that the global spread of AIDS peaked in 1996 at 3.5 million new infections. Deaths peaked in 2004, at 2.2 million. Yet AIDS Day 2009 brings surprising figures: 2.7 million new HIV infections and 2 million AIDS deaths in the previous year.
Researchers have discovered more than a dozen antibodies that target the HIV virus. They hope that these discoveries will lead to a vaccine that offers long-term protection against AIDS. One antibody in particular, PGT 128, is considered among the most potent and promising—preventing about 70% of viruses from infecting cells in laboratory tests.
1.What is the second paragraph mainly about?
A. HIV: from monkeys to humans. B. A hunter's killing caused HIV.
C. HIV is harmless to the chimpanzee. D. HIV is deadly to humans.
2.How many famous people died of AIDS mentioned in the passage between 1985 and 1991?
A. 2. B. 3. C. 4. D. 5.
3.Which of the following statements is true according to the passage?
A. The red ribbon and the World AIDS Day are both the symbols of AIDS solidarity.
B. In 2008, AIDS caused most deaths since 1981 and the death began to go down.
C. In 1986, President Reagan used the word "AIDS" and made a speech on it.
D. During 2001-2002, AIDS is the leading cause of death in the world aged 15 to 59.

A new U．S．government report says more than two million Americans fall ill each year with drug—resistant bacterial infections(感染)，and 23，000 of them are dying as a result．The head of the United States Centers for Disease Control and Prevention[CDC]said that the number probably will grow．Officials warn that steps must be taken now to preserve the effectiveness of antibiotic(抗生素)drugs．
Without urgent action to stop that trend，warned Tom Frieden whose agency wrote the report，the miracle drugs to fight them won’t be available in the future．
“If we are not careful，the medicine chest will be empty when we go there to look for a lifesaving antibiotic for someone with a deadly infection．But if we act now，we can preserve these medications while we continue to work on development of new medicines．”
The report names a drug—resistant abuse of gonorrhea(淋病)，which causes about one quarter of a million hospitalizations in the United States annually．Of the number at least 1 4，000 result in death．
Drug resistance develops through the overuse and inappropriate use of anti—bacterial agents．These can be：doctors prescribing(开药) them to patients who have viral infections that are not affected by medicine meant to fight bacteria；patients not taking all of their medicine as prescribed，so the bacteria making them sick are only weakened，not killed；antibiotic use in healthy farm animals to prevent illness and promote growth．Antibiotic remainders left in meat and animal products can then lead to drug resistance in humans．
To limit the spread of resistant infections，experts recommend wider use of routine immunizations(预防)，as well as hand—washing in hospitals and other health care facilities．Also， the report urges hand—washing by food handlers．?
Michael Bell，deputy director of the Division of Healthcare Quality Promotion at CDC，said Patients also can play a role in preserving the effectiveness of antibiotics by asking health care providers a few simple questions．
1.What’s the best title of the passage?
A．Drug Resistance Developing Quickly in the US
B．Drug—Resistant Bacterial Infections Growing in the US
C．Actions for Preserving Anti-Bacterial Medications in the US
D．Preventions of Drug-resistant Bacterial Infections in the US
2.According to Frieden，we must take measures without delay to preserve effectiveness of antibiotics，or_____.
A．we will have to develop better medicines in place of antibiotics
B．there may be no effective anti-bacterial drugs for use in the future
C．we can’t find other medicines to cure serious illnesses in the future
D．more and more Americans will suffer from bacterial infections each year
3.Of those patients admitted to the hospital because of a drug-resistant abuse of gonorrhea annually，deaths add up to_____.
A．at least 5.6％ B．about 25％ C．about 1.4％ D．at least 2.5％
4.One of the approaches through which drug resistance develops is that_____.
A．people eat the meat with Antibiotic remainder in animals
B．doctors prescribe less antibiotics than needed for patients
C．doctors prescribe much more antibiotic than needed for patients
D．patients don’t take their ant-bacterial agents that doctors prescribe

Cellphone users in the United States have contributed more than $11 million to Haitian earthquake relief through text messages in what is being called as an unexpected mobile response to a natural disaster.
The Mobile Giving Foundation called it a “mobile-giving record” for funds raised for a single cause. Donations are rising swiftly, as former President Bill Clinton and other politicians urge the American people to give.
Jim Manis, chief officer of the organization helping to manage cellphone donations, said it was receiving up to 10,000 text messages per second. The foundation said more than $11 million has been donated.
Cellphone users can donate $5 to Haiti-born hip-hop musician Wyclef Jean’s Yele Haiti Earthquake Fund by texting the word “Yele” to 501501, or they can donate $10 to other nonprofit organizations, such as the American Red Cross, by texting the word “Haiti” to a specified number, like 90999.
The donation is charged to a user’s cellphone bill.
The American Red Cross said it has received more than $ 9 million in donations from more than 900,000 mobile phone users.
“It’s beyond our imagination that we’ve received this amount,” said spokeswoman Nadia Pontif.
Jean’s fund had raised $2 million via text messages, according to Give on the Go, Yele’s mobile application service provider.
The giving is also being fueled by the popularity of websites like Facebook and Twitter, where users are urging one another to make donations using cellphones.
Wireless carriers(无线运营商) Verizon Wireless, AT&T Inc., Sprint and T-Mobile USA, a unit of Deutsche Telekom AG, have waived(免收) fees for customers wishing to send mobile donations. Carriers are also letting users know they are not taking a cut of the donations.
“There are no text messaging fees and 100% of the $10 donation goes to the American Red Cross, and every carrier is working through a solution to push those funds out faster.” Verizon said in a statement.
68. A mobile phone user can donate some money to Haiti by texting the word _____ .
A. “Yele” to 501501 to donate $10 B. “Haiti” to 90999 to donate $10
C. “Yele” or “Haiti” to 501501 to donate $ 5 D. “Haiti” to the American Red Cross to donate $ 5
69. The underlined word “fueled” in the ninth paragraph most probably means “_____ ”.
A. protected B. discouraged C. inspired D. reflected
70. Which of the following statements is TRUE according to the passage?
A. Facebook and Twitter are two relief organizations from the USA.
B. Many American politicians force Americans to give donations to Haiti.
C. The American Red Cross expected to receive much more donations.
D. Carriers have promised not to take a share from the donation.

This season, the bushfires in Australia have burned more than 12.35 million acres of land. At least 25 people have been killed and 2000 homes destroyed. According to the BBC, this is the most casualties(伤亡) from wildfires in the country since 2009. The University of Sydney estimates that 480 million animals have died in South Wales alone.
Zeke Hausfather, an energy systems analyst and climate researcher at Berkeley Earth, said warmer temperatures and extreme weather have made Australia more susceptible to fires and increased the length of the fire season. “The drier conditions combined with record high temperatures in 2019 created main conditions for the disastrous fires. Australia’s fires were worsened by the combination of those two. 2019 was the perfect storm for being the warmest year on record for Australia and the driest year on record for Australia,” Hausfather added on Friday.
Kevin Trenberth, a senior scientist at the US National Center for Atmospheric Research, said warmer ocean temperatures are also contributed to more variable weather around the world. Trenberth believes that global warming contributed to energy imbalances and hot spots in the oceans, which can create a wave in the atmosphere that locks weather patterns in places, causing longer rain events in Indonesia, for example, and at the same time contributing to drought in Australia. He said that once an area experiences drought conditions for two months or more, it increases the risk of fires catching and spreading. Those changing weather patterns due to global warming make drought events longer.
Climate experts stress that climate change is not the only factor in the severity of wildfires. How land is managed can also impact the amount of fuel available for fires. Practices like controlled burns and other factors can impact the risk to people and property, such as warning systems and the type of development in a given area. Changing those policies has great potential to limit future damage from wildfires along with changes to how fire management resources are dispatched(派遣).
1.What do the numbers in paragraph 1 show?
A.The causes of Australian fires.
B.The results of Australian fires.
C.The damaged areas of Australian fires.
D.The property destruction of Australian fires.
2.Which of the following best explains “more susceptible to” underlined in the second paragraph?
A.Quick to adapt to. B.Sure to cause.
C.Sensitive to. D.Easy to be protected from.
3.What can we infer from Trenberth's research?
A.Global warming is the root cause of the bushfires.
B.Longer dry weather contributes to global warming.
C.Warmer ocean temperatures promote fires spreading.
D.The imbalanced energy leads to the temperature rising.
4.What does the author intend to do in the last paragraph?
A.To stress the effects of Australia fires.
B.To show the methods for controlling burns.
C.To predict the seriousness of Australia fires.
D.To provide some advice about reducing damage.

More than 2 million US teenagers have suffered a serious bout（发作) of depression in the past year, 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.
"The data Combined 2004 to 2006 data showed 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(残疾量表), 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 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.
1. The underlined word “ episode ” in paragraph 2 probably means _________.
A. experiment B. experience
C. expression D. feeling
2.What can be implied, but is not stated directly?
A. depression is the third-leading cause of suicide.
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. There were more girl students suffering depression than boys.
3. The main symptoms of a serious depressive episode include ________ .
A. no family or friends or jobs or interests at all.
B. low spirits, lack of sleep, energy and self-image, and poor concentration.
C. poor health, sex discrimination, less energy and loss of interests
D. suicide, sadness, lack of confidence and depression.

More than 30 million people were displaced last year by environmental and weather-related disasters across Asia, and the problem is likely to grow more serious as climate change exacerbates such problems, experts have warned.
Tens of millions of people are likely to be similarly displaced in the future by the effects of climate change, including rising sea levels, floods, droughts and reduced agricultural productivity. Such people are likely to migrate in regions across Asia and governments must start to prepare for the problems this will create, warned the Asian Development Bank.
The costs will be high — about US $ 40 billion — for adapting and putting in place protective measures — from sea walls to re-growing mangrove swamps (红树林沼泽) that have been cut down — that can help protect against the impacts of storm tides.
“While large-scale climate-related migration is a gradual phenomenon, communities in Asia and the Pacific are already experiencing the consequences of changing environmental conditions, including more frequent severe storms and flooding,” the bank said last week. This could lead to a widespread crisis across the region in coming years if preparations are not made to deal with the current and probable future consequence.
Robert Dobias, climate change project chief at the Asian Development Bank, said that, at present, climate change is still a relatively small cause of migration, as economic causes are the most worrying and frightening, and as environmental disasters happen independently of global warning.
The Asian Development Bank warned that governments must start to make preparations now, because more extreme weather has already started to take effect, though the changes so far have not been so great in their impact. The bank is working on a report that will set out in detail the likely problems and suggest a range of potential policy changes to help deal with them.
1.Which of the following is closest in the meaning to the underlined word “exacerbates”?
A.Solves. B.Prevents. C.Worsens. D.Reduces.
2.Which question is answered in the passage?
A.Why climate change happens.
B.What preparations will be made as protective measures.
C.How local governments help people to migrate after climate change.
D.In which part of the globe climate-related migration is most likely to happen.
3.The Asian Development Bank helps deal with the migration problem by ________.
A.working on a report B.changing its migration policy
C.starting a climate change project D.lending money to the governments

The federal school lunch program for 30 million low-income children was created more than half a century ago to combat malnutrition(营养不良). A breakfast program was added during the 1960s, and both attempted to improve the nutritional value of food served at school.
More must be done to fight the childhood obesity(肥胖) epidemic, which has caused a frightening peak in weight-related disorders like diabetes, high-blood pressure and heart disease among young people. The place to start is schools, where junk food sold outside the federal meals program—through snack bars and vending machines—has pretty much canceled out the benefits of all those efforts.
Federal rules that govern the sales of these harmful foods at school are limited and have not been updated for nearly 40 years. Until new regulations are written, children who are served healthy meals in the school cafeteria will continue to buy candy drinks and high sodium(钠) snacks elsewhere in school.
Many states’ school districts have taken positive steps, but others are likely to resist, especially districts that sell junk food to finance athletic program extracurricular activities, and even copier expenses.
Those districts should take note of a study released in 2009 in West Virginia showing that the budgetary costs of switching from sodas to healthy drinks such as fruit juice, milk, and water were very little. Even if the switch costs money, so be it. The school should not be trading their students’ health to buy office supplies.
Over the last five decades, the obesity rates for adolescents have tripled. Unless there is decisive action, weight and inactivity-related disorders will bother a steady larger proportion of the work force and replace smoking as the leading cause of premature death.
1.According to this passage, ______ are to blame for the childhood obesity.
A. weight-related disorders
B. high calorie snacks
C. parents’ bad habits
D. unhealthy lunches and breakfast
2.Which is the main idea of Paragraph 3?
A. Federal governments deserve high praise for their school lunch program.
B. New regulations are badly in need of updating.
C. Children should be forbidden to buy snacks in school.
D. Federal rules encourage snacks outside the school program.
3.The passage is concerned mainly with ______.
A. Malnutrition in low-income children
B. The federal school lunch program
C. obesity at school
D. the nutritional value of food served at school
4.The tone of this passage is ______.
A. negative B. indifferent
C. optimistic D. ironic
