Blue Planet II’s latest episode focuses on how plastic is having a disastrous effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastic in their stomachs. Indeed, the oceans are drowning in plastic.
Though it seems now that the world couldn’t possibly function without plastics, consumer plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s; the same decade that plastic packaging began gaining in popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.
We put all these plastics into the environment and we still don’t really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.
And it’s not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning to the same degree as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers (否认者), at least so far. To do something about it, we don’t have to remake our planet energy system.
This is not a problem where we don’t know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to dispose of it. We know how to recycle. We can all start by thinking twice before we use single----use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag----when taken collectively, these choices really do make a difference.

Construction on Knolly’s Tunnel began in 1896, and it was opened on August 13th, 1898 by the man it was named after--Sir Clement C. Knolly, Acting Governor of Trinidad. It linked Rio Claro with Port of Spain. Its architecture is still admired and studied today, and many are amazed that Knolly’s Tunnel has stood up to the earth’s movement over so many years.
Much research is being done on the tunnel. At the top of Knolly’s Tunnel are cottages covered with leaves, where visitors can sit and enjoy the beauty of nature. Standing at the beginning of Knolly’s Tunnel, you can see nothing but the tiny light at the end. The train tracks have been removed and replaced with small stones. Visitors can drive through the tunnel or walk through, but should do so in groups for safety. In the old days, there were no lights, but now there are street lights on the way to the tunnel, though not inside.
On your way in, you may notice some manholes on the walls of the tunnel. These were there for individuals to step into for safety as the train passed. Knolly’s Tunnel can be accessed through Tabaquite and through Mitchell Gap. The road was recently improved, but is better when you enter from Tabaquite, and there are signs on the road directing you to Knolly’s Tunnel.
On the drive to Knolly’s Tunnel there are two other cottages where visitors can sit and just enjoy nature. At the site itself, there is nothing to purchase to eat or drink, but in Tabaquite there are several bars, a restaurant, and food outlets. A gas station and a health centre are also close by.
For those who admire architecture, Knolly’s Tunnel is a must-see when visiting Trinidad. For the nature lovers, there is no better place for them to be and for the historians, they can walk or drive through Knolly’s Tunnel knowing that many of our ancestors toiled (worked hard) on its structure.

It’s no secret that your personal characteristics directly affect how you interact with the world, but you might be surprised at just how deep it goes. Experts think that your personality can even affect how you exercise and influence what sports are suitable for you.
Highly Sensitive
Highly sensitive people may be more uncomfortable with group exercise classes or team sports where they feel their every move is being observed. Additionally, they may feel more upset over an ineffective or poor workout, says researcher Elaine Aron.
For such people, individual or non-competitive activities like biking, running and hiking are ideal.
Type A Personality
Type A individuals often have an “all or nothing approach” to exercise. This personality type is known for sticking closely to their plan, not to mention being super competitive. However, this can cause them to stick too closely to a fitness routine, which means they might try to push past an injury.
To get better exercise results, Type A people need to be aware that following an exercise plan too strictly may limit their progress. They should be more flexible and listen to their body, especially when they are in pain.
Type B Personality
This laid-back group may get too lazy about their exercise plan, which prevents them from seeing results. They are often less willing to devote enough time and energy to their fitness goals, especially if exercise is something that makes them anxious.
Type B individuals succeed in creative and co-operative environments, so team sports and group gym classes may be perfect.
Remember, there are plenty of ways you can adapt a fitness plan to suit your needs, regardless of your characteristics. Just keep in mind what you like.
1.Why might highly sensitive people be unwilling to take part in group sports?
A. They will feel like they are being evaluated.
B. They don't like socializing with other people.
C. They don't consider themselves to be athletic.
D. They fear they'll be let down by their teammates.
2.Type A personalities can be best described as_________.
A. committed B. flexible.
C. independent. D. sensitive.
3.What is the purpose of the text?
A. To help people understand what personality type they are.
B. To explain how personal characteristics affect exercise habits.
C. To identify the dangers of doing the wrong type of exercise.
D. To describe different types of workouts that are available today.

Nearly 790 million people around the world do not get enough to eat, most of 1. live in developing countries.
A group of researchers in California may have found a way 2.(help) feed the hungry people. Stephen Mayfield, a professor at the University of California, studies on algae(藻类). He says, “The world, in fact, is not short of calories. 3. it is short of is proteins(蛋白质) and essential fatty acids(脂肪酸). Algae are 4.(natural) very high in proteins and fatty acids and those are sort of the two things that the world really needs.”
Mayfield and his team have made algae 5. different kinds of food. Not only is the algae food rich in protein and fatty acids, but it also 6.(taste) pretty good.
And growing algae uses 7.(little) land than other kinds of protein. Mayfield’s big idea is that algae farms could one day replace the huge amounts of land 8.(use) by farmers to produce protein from cattle or soybeans.
Mayfield’s team just successfully finished a test in which they grew algae in an outdoor environment. “Algae food 9.(product) are not yet available for sale. But in the future algae may help feed people threatened by 10.(starve),” says Mayfield.
