Reasons You Might Not Be Able to Donate Blood
Donating blood is a generous — not to mention necessary — act, but there are several restrictions on giving that protect you and future recipients of your gift
The medications you're taking
Most medications won’t disqualify you from being able to donate blood. 1.. If you're taking an antibiotic for an infection, you may be asked to wait until you're healthy again; if you're taking aspirin and donating platelets, you must wait two full days after taking aspirin or any medication containing aspirin before donating,
You’ve tested positive for hepatitis or HIV
2., you cannot donate if you’ve tested positive for either condition. Because some types of hepatitis may not be treatable and can lead to fatal health problems, such as liver failure and liver cancer, it is too risky to donate blood if you have these diseases.
3.
If you weigh less than 110 pounds, you're not eligible to donate blood. Underweight individuals tend to have low blood volumes and therefore may not tolerate the removal of the required volume of blood.
Your iron levels are too low or too high
Having low iron — less than 12.5g/dL for women and 13.0g/dL for men — will disqualify you from donating. For this reason, frequent donors, especially women, are encouraged to take iron supplements and eat iron-rich foods to keep their levels in the normal range. 4..
You recently got a piercing or electrolysis
5., if you've recently gotten an ear or body piercing or electrolysis with a reusable gun or reusable instrument. Before you get a piercing or electrolysis, he recommends doing your research on whether the place employs single-use equipment.
A.Having levels that are too high will also disqualify you from blood donation
B.High blood iron levels increase the risk of diseases
C.But some may require a waiting period after your final dose
D.Since HIV and hepatitis can be transmitted through blood
E.You're underweight
F.When you go donate, make sure you have an updated medication list with you
G.You'll have to wait three months before you can give blood

You're not doomed to toss and turn every night. Although you might not be able to control all of the factors that relate to your sleep, you can adopt habits that encourage better sleep. Start with these simple sleep tips.
No. 1: Stick to a sleep schedule
Go to bed and get up at the same time every day, even on weekends, holidays and days off. Being consistent reinforces （加强） your body's sleep-wake cycle and helps promote better sleep at night. If you don't fall asleep within about 15 minutes, get up and do something relaxing. Go back to bed when you're tired.
No. 2: Pay attention to what you eat and drink
Don't go to bed either hungry or stuffed. Your discomfort might keep you up. Also limit how much you drink before bed, to prevent disruptive middle-of-the-night trips to the toilet. Nicotine, caffeine and alcohol deserve caution, too. The stimulating effects of nicotine and caffeine — which take hours to wear off — can ruin quality sleep.
No. 3: Create a bedtime ritual
Do the same things each night to tell your body it's time to wind down. This might include taking a warm bath or shower, reading a book, or listening to light music. Be careful of using the TV or other electronic devices as part of your bedtime ritual. Some research suggests that screen time or other media use before bedtime has impact on sleep.
No. 4: Get comfortable
Create a room that's ideal for sleeping. Often, this means cool, dark and quiet. Consider using room-darkening shades, earplugs, a fan or other devices to create an environment that suits your needs.
Your mattress and pillow can contribute to better sleep, too. Since the features of good bedding are subjective, choose what feels most comfortable to you. If you have children or pets, set limits on how often they sleep with you — or insist on separate sleeping quarters.
No. 5: Limit daytime naps
Long daytime naps can affect nighttime sleep — especially if you're struggling with poor sleep quality at night. If you choose to nap during the day, limit yourself to about 10 to 30 minutes and make it during the mid-afternoon.
If you work nights, you'll need to make an exception to the rules about daytime sleeping. In this case, keep your window coverings closed so that sunlight — which adjusts your internal clock — doesn't interrupt your daytime sleep.
No. 6: Include physical activity in your daily routine
Regular physical activity can promote better sleep, helping you to fall asleep faster and to enjoy deeper sleep. Timing is important, though. If you exercise too close to bedtime, you might be too energized to fall asleep. If this seems to be an issue for you, exercise earlier in the day.
No. 7: Manage stress
When you have too much to do — and too much to think about — your sleep is likely to suffer. To help restore peace to your life, consider healthy ways to manage stress. Start with the basics, such as getting organized, setting priorities and dividing tasks. Give yourself permission to take a break when you need one. Share a good laugh with an old friend.
Nearly everyone has an occasional sleepless night — but if you often have trouble sleeping, contact your doctor. Identifying and treating any underlying causes can help you get the better sleep you deserve.

In an ideal world, we might be able to live free from discrimination. But not this one, in which we are constantly dividing everything into “us" and “them".
This is especially true during times of fear, like now, when the novel coronavirus is spreading across China and the world. It's a time when “us" means safe and clean while “them" means infectious and risky. Or at least we'd like to believe so.
But this is actually a misbelief, which has been fueled and promoted by fear, and sadly, the media. When the outbreak first started, the term “Wuhan virus" was used in some news, creating hostility （敌意）toward people from Wuhan and Hubei as a whole. There were reports of hotels refusing to accept guests from Hubei and some hospitals denied their entry even when they needed treatment for other medical problems.
Elsewhere in the world, German magazine Der Spiegel labeled the virus on its cover as “Made in China". Australia's Herald Sun, meanwhile, printed, “China Kids Stay Home" on its front page, implying that all kids from China are carriers of the virus. It's also reported that Chinese people overseas have faced harassment （骚扰）and even violence.
This kind of misbelief is exactly why and when the World Health Organization （WHO） was trying to come up with a name for the disease, it had to be careful. “We had to find a name that did not refer to a geographical （地理的）location, an animal, an individual or group of people," said Tedros Adhanom Ghebreyesus, Director-General of the WHO, on Feb 11. And COVID-19 was the final decision.
World leaders and institutes are also sharing sensible voices. "There is no place in our country for discrimination driven by fear or misinformation," Canadian Prime Minister Justin Trudeau said at a Lunar New Year celebration in Toronto on Feb 2. Cornell University also sent an email to students and faculty, saying, “We need to remember to care for one another and not make assumptions about others' symptoms or any characteristics of identity."
It's understandable that during times like this, we want to go to extreme lengths to make sure we're safe. But fear is never part of the cure. Only love and independent thinking takes you further.
1.What is the main purpose of Paragraphs 3 and 4?
A.To explain what has brought about misbelief.
B.To show how some news media misled the public.
C.To compare how different countries responded to COVID --- 19.
D.To present what Chinese people overseas suffer from COVID --- 19.
2.Justin Trudeau and Cornell University are quoted in the text to .
A.show positive attitudes in face of COVID ---19
B.explain why it is important to prevent discrimination
C.describe different opinions of the influence of the virus
D.introduce measures taken by foreign countries to fight COVID---19
3.What's the attitude of the author towards "discrimination"?
A.Neutral. B.Supportive. C.Opposed. D.Unconcerned.
4.What is the main idea of the passage?
A.We should always be willing to care for others.
B.Fear and discrimination are as contagious as a virus.
C.We shouldn't let misinformation influence our own judgment.
D.The media should give people confidence during times of fear.

In a few years, you might be able to speak Chinese, Korean, Japanese, French, and English -- and all at the same time. This sounds incredible, but Alex Waibel, a computer science professor at US' s Carnegie Mellon University (CMU) and Germany' s University of Karlsruhe, announced last week that it may soon be reality. He and his team have invented software and hardware that could make it far easier for people who speak different languages to understand each other.
One application, called Lecture Translation, can easily translate a speech from one language into another. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Users also have to be trained how to use the programme.
Another prototype (雏形机) can send translations of a speech to different listeners depending on what language they speak. "It is like having a simultaneous translator right next to you but without disturbing the person next to you," Waibel said.
Prefer to read? So-called Translation Glasses transcribe (转录) the translations on a tiny liquid-crystal(液晶) display (LCD) screen.
Then there' s the Muscle Translator. Electrodes (电极) capture the electrical signals from facial muscle movements made naturally when a person is mouthing words. The signals are then translated into speech. The electrodes could be replaced with wireless chips implanted (植入) in a person' s face, according to researchers.
During a demonstration (演示) held last Thursday in CMU' s Pittsburgh campus, a Chinese student named Stan Jou had 11 tiny electrodes attached to the muscles of his cheeks, neck and throat. Then he mouthed -- without speaking aloud -- a few words in Mandarin(普通话) to the audience. A few seconds later, the phrase was displayed on a computer screen and spoken out by the computer in English and Spanish: "Let me introduce our new prototype".
This particular gadget (器械), when fully developed, might allow anyone to speak in any number of languages or, as Waibel put it, "to switch your mouth to a foreign language". "The idea behind the university' s prototypes is to create 'good enough' bridges for cross-cultural exchanges that are becoming more common in the world," Waibel said.
With spontaneous (自发的) translators, foreign drivers in Germany could listen to traffic warnings on the radio, tourists in China could read all the signs and talk with local people, and leaders of different countries could have secret talks without any interpreters there.
1. What kind of prototype did the Chinese student named Stan Jou try?
A. Lecture Translation. B. Translation Glasses.
C. Muscle Translator. D. We don' t know.
2.What is the purpose of inventing the translators?
A. To help students to learn English.
B. To help people to watch foreign TV programs.
C. To help people travel in foreign countries.
D. To promote cultural exchanges between countries.
3. What is the best title of this text?
A. Speak different languages at the same time?
B. Flow to learn to speak foreign languages?
C. New ways to learn foreign languages
D. You' re welcome to learn foreign languages

Simply by analyzing a drop of blood, a doctor will be able to diagnose a birth defect or even cancer when it is in the early stage; using new technology, a material lighter but much stronger than steel can be produced.
These may sound like dreams at present. But the dreams may soon come true as research findings in laboratories are being turned into products more rapidly in the new century, according to experts participating in the fourth Asia-Pacific Economic Cooperation (APEC) Technomart, a technology exhibition and trade fair in Suzhou.
"Most people think nano-technology（纳米技术）is too far-fetched to be real. But in fact nano-technology has been applied in a wide range of fields, such as medicine. It is coming into our daily life," said Cheng Jiachong from a Hong Kong-based nano-technology firm.
Nano-technology based on the nanometer, the unit of which is a billionth of a meter, enables scientists to have new concepts of disease diagnosis and treatment on a molecular（分子）and atomic scale, Cheng said.
By using nanometer particles, a doctor can separate the fetus cells（胚胎细胞）from the blood of a pregnant woman to see if the development of the fetus is normal. This method is also being used in the early diagnosis of cancer and heart disease, he said.
One of the most significant impacts of nano-technology is at the bio-inorganic materials interface, according to Greg Tegart, executive advisor of the APEC Center for Technology Foresight.
"By combining enzymes（酶）and silicon chips we can produce biosensors. These could be implanted in humans or animals to monitor health and to deliver corrective doses（剂量）of drugs," he told the participants a technology forum during the exhibition.
"Nano-technology could affect the production of nearly every man-made object, from automobiles, tires and computer circuits（电路）, to advanced medicines and tissue replacement, and lead to the invention of objects yet to be imagined," said David Minns, a special advisor to the National Research Council of Canada.
It has been shown that carbon nano-tubes are ten times as strong as steel, with one sixth of the weight, and nano-scale systems have the potential to make supersonic transport cost- effective and to increase computer efficiency by millions of times, he said.
The experts agreed that the APEC technology exhibition and trade fair provided many chances for exchanges of innovative ideas and products.
