1 . If you wear contact lenses (隐形眼镜), you might not know the best way to deal with old ones. Washing them down the sink or flushing them down the toilet is not the way to go. Yet one in five people who wear contact lenses do just that. However, the plastic in their lenses can linger (存留), polluting both water and land.

Rolf Halden, an engineer at Arizona State University in Tempe, and his team created an online survey. More than 400 contact lens wearers took part. The questions asked how many got rid of their lenses inappropriately. About 20 percent — one in five — sent their used contact lenses down sink drain or toilet. Assuming all contact lens wearers in the U. S. do that at the same rate, the researchers then calculated how much plastic would be flushed away each year. Their estimate: 6 to 10 metric tons! That's about the weight of two to three adult African forest elephants. Contact lenses are a tiny part of the world's plastic pollution. But the unique plastic used in contact lenses could make them a big concern.

To figure it out, researchers exposed contact lenses to the microbes (微生物) used to clean wastewater in water-treatment plants. These microbes made the plastics begin to fall apart, but they weren't fully broken down. Instead, they created a lot of tiny pieces called microplastics.

Halden worries that these small plastic bits will cause trouble in the food chain. In water, the plastics from contact lenses sink. Animals could view these tiny bits as food. But because the plastic won't provide them with nutrition, this could threaten the health of animals who dined on it.

And that's already happening. Many studies have shown that corals, larval fish and shellfish are mistaking microplastics for food. Over time, they risk accumulating even higher levels of plastic in their bodies. Also the pollution has already shown up in bottled water, sea salt and fish sold for human consumption.

1. Rolf Halden's survey shows that ________.
A.contact lenses have won popularity with Americans
B.contact lenses have caused a huge part of plastic pollution
C.some contact lens wearers throw away their old lenses improperly
D.many contact lens wearers don't wear their lenses in the proper way
2. What did the researchers find about lenses in water-treatment plants?
A.They could be broken down completely.
B.They could be processed properly there.
C.They couldn't be affected by microbes.
D.Some of them became microplastics.
3. What does the underlined sentence “And that's already happening” in the last paragraph mean?
A.Tiny pieces are entering oceans.
B.Sea creatures are eating microplastics.
C.Animals are causing plastic pollution.
D.Contact lenses are damaging the environment
4. Which one of the following is most probably to be discusssed next?
A.People's eyesight is getting worse and worse.
B.Contact lenses must be banned immediately.
C.Animals in the sea are lacking in nutrition.
D.The impacts microplastic pollution has on human health.

3 . One of Britain' s most outstanding scientists says the growth in the use of electronic tablets and smart phones is causing people to spend so much time indoors that they need to take regular vitamin D supplements to make up for the lack of sunlight they receive naturally.

Geneticist Steve Jones said he himself was a follower to the cause and urged others to follow. “I never thought I would be a person who would take vitamin supplements;I always thought it was absolute nonsense. But now I take vitamin D every day. Today, because I knew the sun wasn't going to shine, I took an extra one,” he said.

Exposure to the sun is the major source of vitamin D. However, people are spending less and less time outdoors in many areas. The problem is particularly serious in Scotland. "The Scots are the whitest people in the world because their entire body systems are crying out for vitamin D," he said, adding that life expectancy in Scotland is two years shorter than in England or Wales. Multiple sclerosis (多发性硬化症), a medical condition which is often seen in northern Europe, is also higher in Scotland than in England.

Vitamin D helps with the absorption of Ca, which helps keep bones strong. And Jones said the fact that rickets (佝偻病) was making a comeback in Britain after nearly 50 years was another sign of how changing behavior patterns were bringing physical harm.

Jones admitted that concerns over the damaging effects on skin of long-time exposure to the sun were reasonable, but said sunlight was healthy and necessary for the human body, and could help in lowering blood pressure. "If you lie on the beach for an hour, you will drop your blood pressure by about 10 points, because it relaxes your blood vessels (血管). So, get out in the sun while we still can," he said.

1. How are people affected by the rise of technology according to the text?
A.They are more sensitive to sunlight
B.They take more vitamin D supplements.
C.They get less vitamin D than before.
D.They become addicted to electronic games.
2. What’s Jones’ attitude towards taking vitamin D supplements now?
A.Skeptical.B.Cautious.
C.Worried.D.Supportive.
3. Why are the Scots the whitest people in the world?
A.Because they are in great need of sunlight.
B.Because their blood pressure is very low.
C.Because they enjoy a short period of sunshine.
D.Because they are easy to get multiple sclerosis.
4. Which of the following can be the best title for the text?
A.Get out and gain more Vitamin D
B.Keep away from tablets and phones
C.Pay attention to the importance of sunlight
D.Take vitamin D supplements to keep healthy

5 . Are you thinking about traveling alone? You must have a million questions: Where should you go? Will there be someone to talk to?     1     And is it all right to travel alone?

In fact, traveling alone is not as scary (吓人的) as it seems. Here are some good tips.

Choose a place where you feel comfortable and safe

Truth be told, traveling alone for the first time is more about the experience than the destination.     2     It could be somewhere close to home or somewhere you’ve already been with friends.

Make a plan

Always make a plan. That way you’ll avoid worrying too much over where you’re staying, what to see and how you’re getting from A to B.

Book hotels ahead of time

    3     Besides, when you book your hotel, ask if they will send a driver to pick you up.

Talk to people

If you’re going to a touristy place like Thailand, there are lots of other people who are traveling alone.     4     They might also ask you to join them for dinner or a beer. That happens a lot.

Let someone know where you are

Your family and friends love you and probably worry about you every day, so text them and let them know what you are up to throughout your trip.     5     And in case something does happen, they’ll know where you are.

A.How do you stay safe?
B.Don’t draw attention to yourself.
C.That will make you and them feel safer.
D.The first thing you need to do is believe in yourself.
E.So make sure to choose a place that you feel comfortable with.
F.Most likely, they’ll be easy to talk to and they’ll want to communicate.
G.This can make you less nervous when you’re traveling alone for the first time.

6 . Life is filled with regrets. Anyone around you will have no difficulty in telling his regrets. As we get older, we look back and wish that we have made better choices.     1    

Make better plans.

If you start to do something, you need to make a plan before doing it. The earlier, the better.

You will know what comes first and what comes last.     2     If changes happen, you can have more time to deal with them.

Live a more active life.

You can go around more often. More outdoor activities can keep you relaxed and active.     3     “Thank you” can bring a smile to someone’s face. Learn to say “sorry” and don’t be angry with others.

    4    

A friend may make your life and he or she can break your life as well. So you have to think twice when you choose a friend. Good friends will always give you better ideas. When you get into trouble, ask others for help. That little help may get you good results.

Never fear failure.

Everybody fails. Even the greatest person fails before he or she achieves success. We should not fear failure, because failure is not the end of the road.     5    

Life is good. We don’t have to live in our past, but we do hope that we can plan better, live better and work better when we have the chance to do so.

A.You also need to be kind.
B.We must take failure as a chance to learn and improve ourselves.
C.What can we do to avoid future regrets?
D.Regrets play an important part in our daily life.
E.You’ll also know what you should do and what you shouldn’t do.
F.Ask others for help.
G.Find the right friend.

10 . In this modern age, most of us have forgotten to be patient and get angry very quickly over minor things like a traffic jam, a baby crying and such things. It often seems so easy to get what we want right away that when we have to wait even a little while, it seems like we are waiting for ages. We used to be happy to wait 10 - 15 minutes it took to reheat food in the oven(烤箱),but now we’re impatient when waiting two minutes it takes in the microwave.

With the convenience provided by modern society, is patience still a virtue(美德) in the fast-paced world? To begin with, I'd like to share the meaning of the word “patience”. Generally it means being able to tolerate delay without getting impatient. However, it isn't necessarily a passive activity. It takes an active behavior, knowing when to take action and when not to.

So I would argue that patience is still -and always- a virtue. Sure, I used to be one of those who often stared at the microwave for the full two minutes it took to heat my food. And in the end, the food tasted bad. If I had had the patience to heat the food properly in the oven, I would have enjoyed a delicious meal.

Actually the benefits of patience go beyond just heating up our food. Patience is an exercise in self-control which shows that we can exercise good judgment. Lack of patience can cause us to make wrong decisions that negatively affect our health and happiness, waste our time, put us under a lot of stress and affect our relationships in a very negative way.

Everything in life happens for a reason. Sometimes we face an obstacle(障碍) because we need to grow in ways we didn't realize. It's not always obvious when that was happening, but with patience we will soon see clearly why it occurred and what we were meant to learn from it.

Taking time to think about our actions and being patient are a small price to pay when we determine the best possible solution to any problems.

1. The author uses the example of reheating food to show that_______.
A.more people lack patience nowB.high technology brings more benefits
C.people have no time to enjoy the mealD.the fast-paced life makes people stressed
2. What could be inferred from Paragraph 4?
A.People under stress are more likely to get angry.
B.Patient people are less likely to meet difficulties.
C.People with self-control are easier to succeed.
D.Patient people tend to make better decisions.
3. What does the author intend to tell us in Paragraph 5?
A.A wise man learns from experience.
B.A brave man is not afraid of challenges.
C.A man should be patient to deal with difficulties.
D.A man should find out reasons for things occurred.
4. What can be a suitable title for the text?
A.The causes of impatienceB.Is patience really a virtue?
C.Ways to exercise patienceD.What does the word patience mean?
