A California man who was feeling sick almost died recently from a shocking cause.

26-year-old Luis Ortiz went to a hospital because of a headache and nausea(恶心,作呕).When doctors examined him, they were shocked to find a tapeworm larva(绦虫幼虫) in his brain.The story gets stranger.The larva was still alive.

The creature had caused a cyst(囊肿) to form inside his head.The cyst was restricting the flow of liquids to different areas of his brain.The situation was so serious that doctors said they had to perform an emergency operation to remove the larva.

A doctor who operated on Ortiz told him he had only 30 minutes to live.When the doctor pulled the worm out of his head, it was still moving.

Luis Ortiz was a student at California State University in Sacramento.He began experiencing headaches in late August.But Ortiz said he did not think the headaches were serious.

In September, he visited a friend and his parents in another city.That is when the pain got worse.His mother saw Ortiz throwing up and took him to a hospital emergency room.

The doctors saved Ortiz's life.However, the surgery also affected him.Ortiz had to drop out of school and move back home.For now, he is not permitted to work or drive a vehicle.

The U.S.Centers for Disease Control and Prevention says the U.S.has about 1,000 reported cases of tapeworms each year.The CDC adds that tapeworms are more common in developing countries with poor public health systems.

The best way to avoid a tapeworm infection (感染)is to wash fruits and vegetables.Also, make sure meat is cooked thoroughly.The CDC suggests cooking all meats to an internal temperature of at least 63 degrees Celsius.

Your Teen Is Falling Asleep in Class

Teens have a busy morning schedule as they need to wake up and get moving very early in order to catch a bus and get to school by the required time. This means teens need to get their rest the night before or they will be too tired to learn anything at school. 1.

When a teen falls asleep in class, two things happen: he/she misses what is being taught and he/she loses the respect of the teacher. He/She may also receive a consequence (后果) from the school, depending on the classroom discipline (纪律) policy. 2.

To prevent your teen from being sleepy in class, try these three tips:

*Set a time for “lights out” on school nights. This is never be any later than 10 p.m. and preferably 9 p.m. 3. Soft music can be on and used to help calm your teen.

*Help your teen develop a night?time routine that involves activities that slow them down for the end of the day. 4. Turning off the computer and disconnecting from friends and the excitement of the day an hour before bedtime will also help your teen relax.

* 5. This will reinforce (增强) what it feels like to be rested and capable of achieving what he/she wants.

A. What's worse, they may even fall asleep in class.

B. Taking a bath and reading are two activities that work well.

C. Set a good example and show him/her your love for learning.

D. Point out the positives after your teen has had a good night's rest.

E. “Lights out” means the computer, television, lights and cell phone should be off.

F. All of these things affect your teen's academic success and can be avoided.

G. While your teen keeps his/her goals in line with your expectations, he/she may have his/her own goals.

B

We might think we know which colours do what.The idea that red wakes us up or blue calms us down is deeply rooted in Western culture.But do they really change our behaviour in the ways that we assume?

When it comes to scientific research, the results are mixed and at times contested.Some studies have found that people do better on cognitive tasks when faced with red rather than blue or green; others show the opposite.The idea is that if you repeatedly have a particular experience surrounded by a certain colour, then you eventually begin to associate that colour with the way you were feeling or behaving.A school career spent reading your teacher’s red writing circling your mistakes forever makes you link red with danger.Blue meanwhile is more likely to be associated with calmer situations like marvelling at a big blue expanse of sky.

Of course there will always be exceptions --- the comment from the teacher saying “well done” is also written in red.It is true that people do make different associations with different colours, but whether this translates into behaving in a certain way or succeeding at a particular task is a different question.

In 2009 researchers tried to clarify the situation.They sat their participants at computer screens colored blue, red or “neutral” and tested them on various tasks.With a red screen people did better on tasks requiring attention to detail, but when the screen was blue they did better on creative tasks.In practice this might be tricky.In a classroom you might want to think creatively some of the time and pay attention to detail at others.

However, when another team tried to repeat the study with a larger group of people in 2014, the effect of color disappeared.The initial study consisted of just 69 people.In this new, bigger study, of 263 volunteers, background color made no difference.

So colors might well have an effect, but so far those effects have been difficult to demonstrate consistently and sometimes don’t seem to exist at all.

The new high-speed railway line between Urumqi, capital of the Xinjiang Uygur self-governing region, and Lanzhou, capital of Gansu province, has cut train travel time by half to less than 12 hours.

The dramatic improvement will benefit many families planning reunions for Spring Festival.

"For the first time, I feel home is not that far away after all," said Liang Shaofu as he boarded a high-speed train in Urumqi with six members of his family.

The 35-year-old left Lanzhou to set up a dry fruit business in Xinjiang eight years ago, and he has now settled in Urumqi.

The 1,776-km line, which passes through Qinghai province and is the country's first high-speed railway to be built in a high-altitude region, came into service on Dec 26.

"We normally drive home for Spring Festival to avoid the difficulties of buying seven train tickets for the whole family during the peak season," Liang said."Driving can be very tiring and dangerous sometimes, so one year we even decided not to go back to Lanzhou simply to avoid the trip.

More than 600,000 passengers traveled on the line during its first month, and the Urumqi Railway Bureau said the introduction of high-speed services will ease transport pressure during the Spring Festival peak season.

The existing usual railway line could no longer support Xinjiang's development.All passenger trains will gradually shift to the new link, leaving the old one to be used for goods.As a result, Xinjiang's annual goods ability could reach 200 million metric tons from the current 70 million.

The line passes through areas that experience high winds, and it also crosses parts of the deserted Qinghai-Tibet Plateau and the bone-dry sands of the Gobi Desert.

The project could help China to promote its high-speed railway technology abroad, said Ma Xizhang, director of the Lanzhou-Xinjiang railway project's management department in Xinjiang.

1.How long did it take to go from Urumqi to Lanzhou by the usual train before?

A.about 12 hours.

B.About 6 hours.

C.About 18 hours.

D.About 24 hours.

2.What’s the main advantage of the new high-speed railway?

A.It takes more time to go to Urumqi to Lanzhou.

B.It will be more convenient for people all over the country to Xinjiang.

C.All the people in Lanzhou can return home on festivals.

D.It helps to improve Xinjiang’s development.

3.From the passage we can learn _______.

A.Xinjiang’s annual goods ability can increase nearly four times

B.the new railway technology may help more railway lines to be built abroad

C.the high-speed railway lines can’t be built across the bone-dry sands

D.the old railway lines can only carry goods now

4.Which of the following is true according to the passage?

A.The new high-speed railway line is good for all people to go home.

B.The new high-speed railway line benefits businessmen to carry goods.

C.Taking the new train is safer than driving home from Urumqi to Lanzhou.

D.Businessmen seldom went home for Spring Festival before.

Everyone has done experiments in high school laboratories,but have you ever thought about designing a satellite to explore space?

On Nov.19,a team of students from Thomas Jefferson High School for Science and Technology in the US awed peers and even scientists by successfully launching a satellite.

The first satellite designed and built by high school students was sent up into space along with a record setting.28 other small ones on a rocket were sent from a NASA center in Virginia,CNN reported. It took the students seven years to build.

The students call their tiny satellite TJ3Sat,which is named after their school.It is just 10x10x12 centimeters and weighs only 0.89 kilograms,according to Orbital Sciences,a company which developed the rocket and supported the students’ project.It can be controlled with a smartphone.

Like most satellites,TJ3Sat can send and receive datA. The small spacecraft is equipped with a voice synthesizer (合成器),which can switch text to voice and transmit those sounds back to Earth over radio waves,said Orbital officials.In this case,anyone can give it a try via the project’s website (school website) by submitting (提交) a text.The texts that get approved will be sent to the satellite,changed to voice and then broadcast back to Earth via radio waves.

“I can say ‘Go Colonials’on our ground station and when it is on the other side of the world,in India,someone can hear‘Go Colonials’over the radio,”the team explains on the website.

The satellite will stay in space for at least three months.

School principal Evan Glazer told The Washington Post that the project started in 2006 as an activity in the spare time.Later it became a research project for a select group of seniors.

At a time when American students are busy with SATs,the launch of the satellite shows what diligent teenagers can achieve when allowed to pursue their own curiosities,Glazer said.

“It used to be that kids growing up wanted to be an astronaut,” Andrew Petro,program executive (主管) for small spacecraft technology at NASA,said in a statement.“I think we might be seeing kids saying what they want to do is build a spacecraft.The idea here is that they really can do that.”

1.The underlined word “awed” in the second paragraph is closest in meaning to _____.

A. influenced

B. amazed

C. delighted

D. inspired

2.Which of the following statements about TJ3Sat is TRUE according to the article?

A. It took a group of students about a decade to build the satellite.

B. Besides TJ3Sat,28 other small satellites were built by the students.

C. TJ3Sat can receive text messages that the students send into space,which can be changed to voice messages and broadcast back to Earth.

D. TJ3Sat is expected to stay in orbit for the next year,sending out messages together with information about its position in space.

3.According to the article,the launch of the satellite _______.

A. is evidence of the advance of spacecraft technology

B. proves that hard working teenagers can achieve a lot

C. shows the importance of extracurricular activities at school

D. has inspired many people to take an interest in space travel

A new generation addiction is quickly spreading all over the world. Weboholism(网瘾), a twentieth century disease, affects people from different ages. They surf the net, use e-mail and speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive habit. They cannot stop, and it affects their lives.

Ten years ago, no one thought that using computers could become compulsive behavior that could affect the social and physical life of computer users. Such behavior has seriously affected teenagers and college students. They are likely to log(写日志) on computers and spend long hours at different websites.

They become hooked(着迷) on computers and gradually their social and school life is affected by this situation. They spend all free time surfing and don’t concentrate on homework, so this addiction influences their grades and success at school. Because they can find everything on the websites, they hang out there. Moreover, this addiction to websites influences their social life.

They spend more time in front of computers than with their friends. The relation with their friends changes. The virtual life becomes more important than their real life. They have a new language that they speak in the chat rooms and it causes cultural changes in society.

Because of the change in their behavior, they begin to isolate themselves from society and live with their virtual friends. They share their emotions and feelings with friends who they have never met in their life. Although they feel confident on the computer, they are not confident with real live friends they have known all their life. It is a problem for the future.
