Sean and Danielle were leaving the music s
tore when they heard the crash. "What do you suppose that was?" asked Sean.
"I don't know for sure," said Danielle, "but it sure sounded bad. It's right over there. Let's go and look."
Sean and Danielle knew they would see an accident. But they didn't know what to expect. There in the middle of the street was a bicycle that had been hit by a car. The bicycle rider was sitting in the street, shaking his head.
"Look at that," said Sean, "he's not even wearing a helmet. He is one lucky guy".
"No kidding," Danielle replied. "Look at the driver of the car. She's just as lucky. She's not wearing a seat belt.
Sean and Danielle are right. The bicycle rider is very lucky, he was not hurt. Riding a bicycle is a lot of fun, but it can also be very dangerous. You have to pay attention all the time to what you're doing. You also have to follow safety rules.
When you ride a bicycle, remember that you share the road with cars and trucks. These vehicles are a lot bigger than you are. So, always wear a helmet when riding your bicycle. Always means "every time" even if you are just riding around the block.
Follow the same rules as car and truck drivers. Bicycle riders also have some special rules. Here are some special rules you should follow:
● Do not ride your bicycle on the sidewalk. By not riding on the sidewalk, you won't run into a pedestrian.
● Ride on bike paths or trails when they are available.
● Always ride in the same direction as traffic.
● Always ride on the right-hand side of the road.
● Wh
en you ride with a friend, do not ride next to each other. Ride in single field, one behind the other.
● Obey all traffic signals and signs. Stop at all stop signs.
● Walk your bicycle across busy crossings.
● Be sure to use hand signals when you turn and stop.
Follow
these safety rules when riding a bicycle at night.
● Have a headlight that works.
● Have these r
eflectors on your bicycle: yellow or white in front, and red ones on the pedals and back.
● Wear light-colored clothing so drivers can see you.
You should always keep your bicycle in good working order. Make sure the brakes work properly and that your tires have enough air. If you find anything wrong with your bike, fix it or have it fixed before you ride it again.How did Sean and Danielle know that they would see an accident?

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.The text mainly discusses the relationship between .

Millions of people die of hunger in southern Africa every year, but when Zambia was offered thousands of tons of free maize by the US, the government politely paid no.
“We don’t know whether the food is safe,” said Zambia’s commerce, Trade and Industry Minister Dipak Patel.
His worries are shared by countries around the world that are in two minds about America’s genetically modified（GM，转基因的）crops. Just last week, EU（欧盟）member nations were discussing whether or not to import GM sweet corn from the US.
Ever since people started farming, they have tried to crossbreed（杂交） plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other.
But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature.
This means they can make crops more productive and resistant to disease by adding genes from other species. They can also create food with special characteristics, such as “golden rice”, which is enriched with vitamin A. But many people believe GM foods are a health risk.
“If left to me, I would certainly not eat GM foods,” said Scottish scientist Arpad Pusztai. “We are putting new things into food which haven’t been eaten before. The effects on the immune system（免疫系统） are not easy to predict.”
At the moment, the official argument is that GM foods “are not likely to present risks for human health”. But there are still many questions to be answered as the foods are produced in different ways.
Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops. We learn from the passage.
| A．people have discovered that GM foods will do harm to human health |
| B．millions of Zambia people die of eating too much GM foods |
| C．people are still not sure if GM foods will do harm to human health |
| D．genetic material added to plants will damage our bodies sooner or later |
What does “in two minds” in the third paragraph mean?
| A．Unsure |
| B．Worried |
| C．Likely |
| D．Careless |
The following statements is NOT true about GM foods?
| A．It is produced from plants added genes from other species. |
| B．GM foods can have special characteristics. |
| C．GM foods will affect people’s immune system. |
| D．GM foods have been produced since 1970s. |
Adult Basic Education (ABE) and GED Preparation
Task
The Adult Basic Education Department serves a huge population of learners. Our task is to teach basic skills and help learners to get more knowledge to function effectively as a family member, citizen, worker, and lifelong learner in a changing world.
Description
ABE is a non-credit program of self-improvement designed to improve basic skills for students who are of different educational levels. Development of reading, writing, and math skills are paid special attention to, as well as life skills, employability, and technology. Students without a high school diploma（文凭）also have the opportunity to prepare for the GED exams in the five subject areas: writing, social studies, science, literature, and math.
Prerequisites（条件）
ABE classes are open to anyone 18or over who desires to improve basic reading, writing, and math skills at the pre-college level. Students who are 16 or 17 must first obtain an official release（释放）from high school before attending class.
To be accepted, students must attend an Educational Planning Session. During the Educational Planning Session students will be given an overview of the ABE programs as well as PCC policies, fees, etc, Students will also have their reading, writing, and math abilities assessed（评估）during the Educational Planning Session. The results of their assessments will help the teachers develop individual programs of study for students to guide them toward their personal goals. Students needing special help must get in touch with the Office for Students with Disabilities (503-977-4341) at least two weeks before the session is held.

Technically the domain name system consists of three parts. First is the addressing system of Internet Protocol(IP)numbers, the 32-bit numbers that are the true addresses of computers connected to the Internet. Next is the naming system, the by-now familiar names that include .com .org .edu .etc., which are collectively known as top level domains, or TLDs. The naming system was devised to find a computer or send email. Finally, there is the routing system, which “maps” domain names to IP numbers. Computers called “root servers” contain a kind of giant directory that links specific names to specific addresses on the Internet.
There are several political headaches about domain names that have no clear solutions. Because domain names have to be unique, they are inevitably linked to trademark disputes when two or more businesses, or people, want the same name.
Domain names also raise issues of privacy. Using a search tool such as the Whonami Global Internet Name Search site, anyone can look up the name and address of whoever is registered as the owner of a domain name.
In 1998, the U.S. government handed over management of the entire domain name system to the Internet Corporation for Assigned Names and Numbers, or ICANN, based in Marina Del Rey. ICANN’s board of directors held one of its periodic general meetings recently in Stockholm, an event that featured an outpouring of frustration and controversy about how the group is managing its new responsibilities.If you want to send email, you must own the following except.
| A．a computer |
| B．the addressing system |
| C．a domain address |
| D．a telephone line or cable |
Which of the following is NOT true?
| A．The domain name system was once under the control of the U.S. government. |
| B．The general meeting of ICANN is held on a regular basis. |
| C．Two businesses can have the same domain names. |
| D．Search sites help people to get information about domain name owners. |
The purpose of naming system was to.
| A．link specific names to specific addresses on the Internet |
| B．find people on computers. |
| C．distinguish computers or send email |
| D．solve problems for businesses and people |
Domain names which have no clear solutions.
| A．cause people’s headache |
| B．cause difficult situations for the government |
| C．get businesses to change their trademarks |
| D．force businesses to put trademarks on their goods. |
