D
Life has changed in Mexico City．Streets normally filled with people are empty．One of the most popular professional soccer teams recently played a game in an empty stadium that can seat more than100,000 people．It's swine （猪）flu that has made life in Mexico City grind to a halt （慢慢停了下来）．
Seemingly out of nowhere, swine flu has caused confirmed deaths in 12 countries as of April 30．It has sent a wave of alarm around the world．Governments are trying to find ways to prevent further out-breaks．The World Health Organization has raised its swine flu global threat level to five out of six．
People may be familiar with bird flu, but they know little about swine flu．Swine flu is a contagious（传染性） respiratory（呼吸的）disease in pigs．It is caused by a type-A influenza virus．
Humans can also catch swine flu．The virus causes regular outbreaks in pigs, but people usually do not catch it．However, there have been cases of the virus spreading to people, and then from one person to another．
The symptoms of swine flu are similar to the common flu．They include fever, lethargy （无精打采）, lack of appetite, coughing, runny nose, sore throat, nausea（恶心）, and vomiting （呕吐）．The high proportion of young adults among the deaths is one of several mysteries about this virus．Most of the dead had lung damage．What caused it is not yet known．
The virus spreads the same way the common flu does．When an infected person coughs or sneezes around another person, the latter is put at risk．People can get the disease by touching something with the flu virus on it and then touching their mouth, nose or eyes．
There are medicines to treat swine flu．Doctors suggest using anti - viral drugs．They keep the virus from reproducing inside the body．
And there are vaccines for it now, several everyday steps can also help prevent the spread of the virus: washing hands frequently; avoiding close contact with people who are sick; and avoiding touching surfaces that might have the virus on it．
People may worry that they will get swine flu from eating or preparing pork．In fact, you cannot catch the virus from pork products if they have been properly prepared and cooked．Cooking food at temperatures of 71℃ kills the virus．
69．What is the main idea of the passage?
A．It mainly tells us how swine flu broke out in Mexico City．
B．It presents the reader with some information concerning swine flu．
C．It tells us the differences between swine flu and bird flu．
D．It mainly tells readers the dangers caused by swine flu．
70．The following tips can protect us from swine flu EXCEPT _________．
A．keeping us away from other people
B．washing hands frequently
C．avoiding close contact with sick people
D．avoiding touching surfaces that might have the virus on them
71．What's the main idea of the first paragraph?
A．Mexico City is really a place of horror now．
B．People in Mexico City like staying at home．
C．People in Mexico City don't like soccer．
D．Swine flu has seriously affected people's life in Mexico City．
72．What can we infer from the passage?
A．At present there still aren't effective vaccines for swine flu．
B．Swine flu is preventable，controllable and curable．
C．From now on, people can't eat pork if they want to be safe．
D．All of the dead killed by swine flu had lung damage．

The world record for fastest text message typing is held by a 21-year-old college student from Utah, but his flexible fingers could mean serious injury later on. Most adults aged 18-21 prefer texting over e-mail or phone calls, and ergonomics(人体工程学) researchers are starting to wonder whether it’s putting the younger generation at risk for some overuse injuries – once reserved for older adults who have spent years in front of a computer. Judith Gold, an assistant professor of Epidemiology at the College of Health Professions and Social Work, thinks this might be the case. At this year’s annual meeting of the American Public Health Association, she presented previous research which suggested that among college students, the more they texted, the more pain they had in their neck and shoulders.
“What we’ve seen so far is very similar to what we see with office workers who’ve spent most of their time at a computer,” said Gold, who directs the Ergonomics and Work Physiology Laboratory. “The way the body is positioned for texting – stationary（不动的）shoulders and back with rapidly moving fingers – is similar to the position for typing on a computer.”
Text messaging is a fairly new technology, Gold says, so this is a new area of research among ergonomists. “But given the similarities in body position, findings from research on overuse injuries from computers could be applied here,” she said.
Current studies on computer use show office workers have the tendency to get involved in such diseases as tunnel syndrome, bursitis, and tendonitis.
In Gold’s lab, she and her team use tools like special cameras, motion analysis and heart rate monitors to study the body’s position in several job-related situations. But given the popularity of text messaging among young adults, Gold wants to explore further into the physiological effects of this latest form of communication.
“Looking around our campus, you see every student on their cell phones, typing away,” she said. “It’s the age group that texts the most, so it’s important to know what the health effects may be in order to learn whether it will cause long term damage.”
64. Which of the following are ergonomics researchers not sure about?
A. A 21-year-old college student holds the world record for fastest text message typing.
B. Most adults aged 18-21 prefer texting over e-mail or phone calls.
C. Overuse of computer will cause injuries to health.
D. Over text message will cause long term damage to health.
65. Current studies on computer use will lead people to believe that ______.
A. office workers are good at texting messages
B. office workers tend to suffer from some kinds of physical problems
C. texting messages seriously damage people’s health
D. e-mails and phone calls will be forbidden
66. When texting messages, college students will ______.
A. keep moving shoulders and back
B. move fingers very fast with shoulders and back still
C. spend most of their time at a computer
D. look around their campus
67. The most suitable title of this passage may be ______.
A. Over text messaging could cause shoulder and neck pain
B. Overuse of computers could cause diseases
C. A new world record for fastest text message typing
D. A new scientific discovery by ergonomics researchers

查看习题详情和答案>>At about 4 am, after hours of being unable to sleep, of shivering in the cold mountain air and trying to silence my crying kids who kept waking up, of attempting to find a comfortable sleeping position, of listening to whether there might have been a bear outside our tent, I finally couldn’t stand it any more. I complained, “Everything has gone wrong.”
My wife and I were in one tent with our two young kids. A hundred yards east away was Summit Lake, where the glorious early morning mist was shimmering（闪烁）off the water. A couple miles to the southwest was the base of the Lassen Peak Trail. The base was 8,000 feet above sea level, and huge snow dotted the scenery even in mid August. Further west still was Bumpass Hell, with steam rising up.
As the sun crept up over the edge of the Lassen peak, we fired up the camp stove and had breakfast. Half an hour later, my six-year-old daughter and I were in the parking lot of the Lassen peak trail, getting ready to go up the mountainside. We wouldn’t make it all the way, but it didn’t matter. We would see nature at its extremes: the volcanic ash that layered on the earth turning the melting snow a mysterious pink as the sun struck it; the blues of the sky shading into the blues of distant lakes, which in turn shaded into the whites and grays of the snow.
My daughter grabbed my camera. She wanted to take a photo of “the composite（混合物）”of colors. Looking out over that scenery, and seeing my daughter fascinated by nature, I felt stupid about my morning complaints.
Yes, camping is uncomfortable. And yes, there’s a lot to be said for getting out a credit card,reserving a room in a nice hotel, and going out for a fancy meal. But there’s also something wonderful about being so close to raw nature. And , as important, there’s something vital about getting young children out of their increasingly modern comfort zones and forcing them to meet the world around them.

You could be a heroic hunter by expecting to fight against evil monsters or the fastest F1 driver around .In the world of computer games, nothing is impossible.
If you’re into computer games, E3 is where you can find the most up-to-date equipment．For both gamers and companies, the Electronic Entertainment Expo （E3）, held in Los Angeles, US, for three days from May 10, was a carnival （狂欢节）.
The top three computer game manufacturers （生产商） in the world all showed off their new machines. Nintendo’s （任天堂） new game controller looks as easy to use as a TV remote.
Sony’s PlayStation 3 combines the world’s most powerful game console （游戏机） with a next-generation DVD player.
Microsoft’s Xbox 360 can connect to personal computers （PC．and cell phones, so users can transfer game content among the three systems.
PC VS Console
The E3 also had new games for both PCs and consoles such as the Xbox or PlayStation. Gamers will again be faced with the long—existing problem of which system to use.
Some analysts have suggested that PC gaming has seen its day, since console players have made great advances.
Further, compared with a PC, a console is cheap. The average price of the PlayStation and the Xbox is only one-third of that of a personal computer.
One of the biggest advantages the PC has over consoles is that there are a lot more games available, plus many are free to download. PCs also give gamers a variety of ways to connect to the Internet, and to one another.
However, many consoles now support online games as well. It seems that as long as people can be dragon（龙）hunters or crazy drivers, it doesn’t matter whether it is on a PC or a console.
