1 . The human brain remembers negative experiences more easily than positive ones. Our brains have developed in this way because threats, like dangerous animal, have a more immediate effect on people's survival compared to positive things like food or shelter. As a result, you clearly know what makes you unhappy, but do you know what makes you happy?
Research suggests that our level of happiness is partly shaped by the choices we make. If you've been chasing wealth, fame, power and some material things, you may be looking for happiness in the wrong places. Psychologists suggest that the following habits can make people happier.
People who own close relationships tend to be happier than those who do not. The number of our friends is not important. What matters is the quality of our relationships. Relationships that bring happiness usually consist of the sharing of feelings, acceptance, mutual respect and trust.
People who exercise regularly can improve both their physical and mental well-being. Some research has shown that exercise can be as effective as some medicine in treating depression.
If we are so interested in an activity, we may lose track of time, and we can be in a state of flow. The activity could be playing the piano, surfing the Internet or playing a game. People who experience flow in their work or life tend to be happier.
People are more likely to be happy if they know what their strengths are and can use them regularly. People are especially happy when they can set goals and use their strengths to achieve them.
People, who think positively by being grateful, mindful and optimistic, are more likely to be happy. Being grateful means being thankful. Being mindful means considering, focusing on, and enjoying the experiences of the present moment. Being optimistic means being hopeful about the future.

2 . Public Health England (PHE) is targeting pizzas, ready meals, ready meat and takeaways. The government has also required the food industry to start using healthier food and encourage the public to choose lower calorie (卡路里) foods.
It is all part of an effort to cut calorie intake by 20% by 2024. The target will point to 13 different food groups, which are equal to about a fifth of the calorie taken by children. If action is not taken, PHE said, it would be prepared to ask the government to pass laws.
PHE would strictly monitor the progress by looking at which products people buy and would be prepared to punish companies which do not take on their duties. The government is also organizing a program encouraging adults to consume (吃，喝) 400 calories at breakfast and 600 each at lunch and dinner.
At present, adults consume between 200 and 300 calories more than they should each day. PHE chief nutritionist Dr. Alison Tedstone said the 400600600 tip would make it easier for people to make healthier choices by being able to judge what they should eat at each meal.
How many calories should we eat? It is suggested that a woman eat no more than 2,000 calories a day, while a man should limit his intake to 2,500. For children, it depends on the age. A fouryearold should consume no more than 1,300 calories a day, while for teens aged 17 and 18, it is about 3,000, but overweight children are eating up to 500 calories more than that.
Prof Russell Viner, from the Royal College of Pediatrics and Child Health, said it was a necessary move. He said, “Over the past 40 years, there has been slow growth in food sizes, with pizzas and hamburgers simply much bigger than they were in our parents' time.” The convenience of fast food and the advertisement of unhealthy food and drinks to children add to the problem.

3 . As I stuck in the mud (泥), with my bike on top of me, I wondered what had forced me to come here. Madagascar is not a good place for a cycling holiday: one of the world's poorest countries, only 11 percent of roadway is paved (铺). South of the town of Antalaha, where I started, the road was in worse condition.
I appeared from a week in the wilderness and reached the start of the Route National 5 at Maroantsetra, but my dream of a smooth road and speed was suddenly destroyed by mud. The "worst road in the country" changed my bicycle into a burden (负担) for days. Finally, I was claimed by the road. Tired. Alone.
As I wiped (擦) the mud from my face and looked upwards, I was greeted by a Malagasy man. He helped me stand up and smiled playfully while he pointed to my bike, which sat next to his. I started again. But I fell again in the mud. Angrily, I told him to go on, but if he understood he showed no sign of it. His smile forced me back onto the bike. We continued like this for hours. But I fell less. Studying my quick guide, slowly I learned. As we passed through a village, a group of children saw me and shouted loudly. His only words were: "Their parents tell them while people steal and eat them. Funny, no?"
I tried to ask why, but he had already set off. I tried to catch up; as I got closer, he took it as a challenge and sped up. We raced along the road. I rode a little faster and I was just behind, about to catch up with him. With a smile, he sped up and was away, leaving me breathless.

4 . All of us spend a large part of our lives at home — eating, sleeping, relaxing and communicating with our family members. Our home is a shelter for us, away from the noisy, busy, and polluted world outside — a place where we can let down our hair and dress casually. Ecofriendliness (环保) is a hot word today and we all know we should make our environment as ecofriendly as possible. This is not only good for our health, but also good for the outward environment. Here are some easy and helpful tips to make your home ecofriendly.
Kitchen
Plan the kitchen to be bright and airy so that you don't have to turn on the lights at daytime. Don't make wasteful use of the gas. Keep all ingredients for cooking ready before lighting the gas. Turn it to low when not required — always using it on "high" burns a lot of gas.
Indoor plants
Plants are extremely ecofriendly and can be used to make your home look lively. Apart from adding life to home, they give out O2, thus making the air inside fresh. You can keep plants in your home, but be sure to show them some sunlight regularly. Also, if they are kept outside, clean their leaves with a wet cloth, as dust may be added to them. A home decorated (装饰) with plants looks attractive. Plants are a natural home decorating gift that shows concern about the environment. A green plant is a wonderful gift which will protect the earth and is sure to be appreciated.
Saving water
Most of the time, we take water for granted — we keep water running while brushing our teeth or washing clothes. Needless to say, this is a huge waste of natural resources (资源). Try to recycle water. For example, the water used for washing vegetables can be used for watering plants; the soapy water used for washing clothes can be used to clean the bathroom and kitchen.
1. Why is the importance of our home discussed in Paragraph 1?| A．To advise us to communicate more with our family members. |
| B．To show it's necessary to make our home ecofriendly. |
| C．To advise us to spend more time staying at home. |
| D．To show the outside world is noisy and polluted. |
| A．To open the window. |
| B．To prepare simple meals. |
| C．To save energy. |
| D．To turn down lights. |
| A．We don't realize the importance of water. |
| B．We try our best not to waste water. |
| C．We don't use water frequently. |
| D．We make full use of water. |
| A．Live a relaxing life. |
| B．Create a clean and safe home. |
| C．Our home is a shelter for us. |
| D．Make your home ecofriendly. |
5 . If you're reading this, you were probably born in the 2000s. The oh-ohs(00后）．The 21st century. That would make you young,creative, connected, global,and no doubt smart. Maybe good-looking,too. Right? But what do other people think about your generation?
Some adults worry that you're more interested in the screen in front of you than the world around you. They think of you as the“face-down generation” because you use your phone so much and they wonder how you will deal with school, friends,and family. Are today's teenagers too busy texting and taking selfies(自拍）to become successful in real life-or“IRL”， as you would say?
Other adults worry that today's youth are spoilt(宠坏的）and don't want to face the challenges of adult life. Many children born in the 1990s and 2000s were raised by"helicopter parents” who were always there to guide and help them with a busy schedule filled with homework and extra-curricular activities such as dancing, drawing, or sports. With partners who do everything for them, today's youth seem to prefer to live like teenagers even when they are in their 20s or 30s.
Does the face-down generation need a heads-up?Well,probably not. The fact is that many of today's teenagers are better educated and more creative than past generations. They also seem to be enthusiastic(热情的）and willing to become leaders. More young people than ever volunteer to help their communities. There are also brave young people such as Malala Yousafzai,the teenager who won the 2014 Nobel Peace Prize for pushing girls' rights to go to school.
So if you're one of the oh-ohs,there's reason to be hopeful about the future. Things are looking up for the face-down generation. Chances are that you will do GR8(great) and LOL（laugh out loud).

6 . A rich woman went on a trip in Thailand, and she took her pet dog with her. One day the dog started running after butterflies and before long he discovered that he was not able to find his way back. When wandering about ,he noticed a tiger heading quickly to him with the obvious desire of having lunch.
The dog thought,"God,I'm in deep trouble now.”
Then he noticed some bones on the ground nearby, and at once stopped to eat the bones with his back to the tiger.
Just as the tiger was about to jump,the dog said to himself loudly,"Hey,that was one delicious tiger. I wonder if there are any more around here?” Hearing this, the tiger stopped jumping,and ran away into the trees.
“Oh,” said the tiger,“That was dangerous. That dog nearly caught and ate me. ”
At the same time,a monkey who had been watching the whole scene from a nearby tree, thought maybe he could make good use of this chance and trade it for protection from(免遭···的伤害）the tiger.
So,off the monkey went. He soon caught up with the tiger,and told the tiger the truth.
The tiger was very angry at being made a fool of and said, “Here monkey, stay on my back and see what's going to happen to that dog. "
When the dog saw the tiger coming again with the monkey on its back,he thought,"What am I going to do now?”
But instead of running, the dog sat down pretending he hadn't seen them yet.
Just when the monkey and the tiger got close enough to hear,the dog said,"Where's that monkey? I can not trust him any longer. I sent him off half an hour ago to bring me another tiger as my supper, and he's still not back!”

7 . If humans ever hope to live on the Mars, the settlers will need to produce a series of organic compounds (有机化合物), from fuels to drugs, which are too expensive to ship from Earth.
Chemists from University of California, Berkeley, and Lawrence Berkeley National Laboratory (Berkeley Lab) have a plan for that.
For the past eight years, the researchers have been working on a system combining bacteria and nanowires (细菌和纳米线) that can catch the energy of sunlight to change carbon dioxide (CO,) and water into building blocks for organic things. Nanowires are thin wires about one-hundredth the width of a human hair, used as electronic parts, and also as solar cells.
“On Mars, about 96% of the atmosphere is CO2. Basically, all you need is these nanowires to take in the solar energy and pass it on to these bacteria to do the chemistry for you,” said project leader Peidong Yang, professor of chemistry and the S.K. and Angela Chan Distinguished Chair in Energy at UC Berkeley. “For a deep space task, you care about the weight, and biological systems have the advantage that they self-reproduce: You don’t need to send a lot. That’s why this version is highly attractive.”
The only other requirement, besides sunlight, is water, which on Mars is relatively more than enough in the polar ice caps and likely lies frozen underground over most of the planet, said Yang.
It works like photosynthesis (光合作用), which plants naturally employ to change CO2 and water into carbon compounds, mostly sugar and carbohydrates. Plants, however, have a quite low efficiency (效率), usually changing less than one-half percent of solar energy into carbon compounds. Yang’s system is comparable to the plant that best changes CO2 to sugar, which is 4～5% efficient.

9 . Earth's forests are emptying.
Half of their inhabitants(栖息动物) have disappeared in the last 40 years, according to a latest report from the World Wildlife Fund (WWF).
The report tracked populations of 268 species of forest-dwelling birds, mammals, amphibians, and reptiles worldwide between 1970 and 2014(the most recent year for which data is available). The results show that forest animal populations have declined by 53% worldwide, and humans are to blame.
More than 80%of all land animal, plant, and insect species call forests home. However, a combination of habitat destruction, hunting, the spread of invasive species, climate change, and diseases are killing off forest animals, the researchers said.
Without those animals, forests can't perform the functions we rely on, since animals pollinate(授粉) forest plants, spread seeds, and nourish the soil with their waste.
“Forests depend on a complete animal world to perform. functions essential to life,” Susanne Winter, a program director at the WWF, told Eco Watch.
One of the most critical roles forests play is in easing climate change. Trees suck enormous amounts of carbon dioxide out of the air and embed (吸纳) the carbon in their wood and the soil. A recent study found that planting new trees over an area the size of the US could suck away two-thirds of all the carbon dioxide emissions that humans have pumped into the atmosphere.
“Without animals, it is harder for forests to absorb carbon, as tree species important for protecting the climate could be lost without animals,” Winter said. Without them, those trees would have difficulty reproducing and forests would lose their best carbon-storing trees.
“Forests are our greatest natural ally in the fight against global warming,” Winter said. “If we want to reverse the worldwide decline in biodiversity and prevent the climate crisis, we need to protect the forests and the species living there.”
