The agreement came after two weeks of talks between the leaders at the 21st Conference in Paris, France. As part of the Paris agreement, countries said they would cut down on pollution However, according to the terms of the deal, countries that don't do this will not be punished, or fined. Instead,the document is meant to show that governments around the world take climate change seriously and are willing to work together to fight global warming. World leaders have met many times to discuss climate change. But, the 21st Conference of Parties, or COP21, which began on November 30 in Paris, was the first time they agreed on a global, legal pact . Before the conference, each nation was asked to create plans on how to reach the shared goal. The pact that was signed allows countries to decide the best way to cut down their gas pollution. No matter how they decide to go green, each country must report honestly on all of their efforts. Every five years, nations must look at the work they've done and submit new plans on how they will improve over the next five years. In the pact, the countries pledge to limit the amount of greenhouse gases emitted by human activity to the levels that trees,soil and oceans can absorb naturally. It urges countries to spend trillions of dollars on creating new energy sources, like solar and wind power. It also requires countries to raise at least $ 100 billion each year to help developing countries. However, critics of the pact say it is not detailed enough, and doesn't include specifics about how the plan will be enforced and how improvements will be measured. The pact does include one large, specific goal: how countries will aim to keep global temperatures from rising more than 3. 60degF(20degC) by 2100. Nonetheless,the agreement is considered by many world leaders to be a major victory. The U. N. has been working more than two decades to convince governments to work... Question: When was the legal pact probably passed? - On November 30. - On December 4. - On December 8. - On December 12.

I want to travel with you---just you. I want to explore a new place alongside a woman who raised me, who put up with my teenager anxiety and my rebellious college years. I want to see my favorite cities with the lady who taught me basic life lessons, such as looking both ways before crossing the street, how to use a glue gun, and that the most important thing in the world is to help others. I always appreciated the vacations you planned for our family. I also remember how you watched me as I read The Great Gatsby on the balcony at midday. I wonder if you felt proud of me. These days, I am sick of traveling to places with wishy-washy friends. I want to travel with a strong woman who can see how capable I am of learning to speak French or hiking on a glacier or eating something as unpleasant-smelling fruit. Now I want you to see how much I grow up while abroad---I'm a different person, Mom. And I know you'd be different too. I know that someone has shared a similar burst of emotion while diving into Australia's Great Barrier Reef for the first time. So what do you say, Mom? Will you _ ? I want to travel with you. Let's just go---we can go anywhere in the world, just you and I. You can pick the place, and I will do the rest. Love, Katka Question: Which life lesson does Katka think the most valuable? - Exploring a new place alongside her mother. - Visiting favorite cities with her mother. - Looking both ways when crossing the street. - Offering help to others when it's possible.
Offering help to others when it's possible.

Q: Read the following article and select the best answer. Article: About 90 percent of Chinese believe the polarization between the rich and poor is "serious" in China, according to a survey conducted by China Youth Daily. And more than 80 percent of the respondents surveyed said something must be done to narrow the expanding gap between the rich and poor, while 14.1 percent said it was necessary. The polarization has aroused wide concern among the public in recent years. The State Development and Reform Commission said the _ had reached 0.47 for China, up from o.29 two decades ago. Usually, a country with a number above 0.4 is warned to pay attention to the income inequality problem. To find out the people's view, the survey covered 10,250 respondents, between the ages of 20 and 30 with a college education and a monthly salary between 1,000 and 3,000 yuan. Surprisingly, most disagreed with the view of experts who claim the urban-rural difference is causing the widening gap. More than 70 percent of the respondents believed that " the group of special interests" is the prime reason for the polarization, followed by "people in power" 68 percent, and "bosses" 50 percent. Another unexpected finding is that almost all agreed that a good educational background and knowledge were not the decisive factors in gaining wealth. About 95 percent said rich people are not necessarily those who are able to speak English or have a college education. Today in China, rich people , accounting for 10 percent of the population, control 45 percent of the total social fortune, and poor people, also 10 percent of the population, only control 1.5 percent, according to an investigation published by the National Bureau of Statistics last June. Question: Experts hold the view that the main reason for the polarization is _ . - the urban-rural difference - the group of special interests - the people in power - the bosses
A: the urban-rural difference

Q: Read the following article and select the best answer. Article: Scientists have transformed men's minds into avirtual woman's body in an experiment that could throw light upon how humans distinguish themselves form others. In a study at Barcelona University, men wore a virtual reality headset that allowed them to see and hear the world as a female character. When they looked down, they could even see their new body and clothes. The "body-swapping" effect was so convincing that the men's sense of self was transferred into the virtual woman, causing them to react to events in the virtual world they wereimmersed . "This work opens up another avenue for virtual reality, which is not just to transform your sense of place, but also your sense of self," said Mel Slater, "If you can temporarily give people the illusion that their bodies are different, then the evidence suggests it also affects their behavior and the way they think. They can have new experiences: a person who is thin can know what it is like to be fat. A man can have an experience of what it's like to be a woman." During the experiment, a "female" approached and hit the face of the character another man was playing. "Their reaction was immediate," said Slate. "They would take in a quick breath and maybeflinch . The more people reported being in the girl's body, the stronger physical reaction they had." But in all cases, the feeling was temporary and lasted only as long as the study. The study shows that our minds have a very fluid picture of our bodies. The research is expected to shed light on the puzzle of how our brain tells the difference between a part of our own body and something else in the wider world. Thus the work might improve the conditions for those who have experienced strokes by placing them in a world that helps them to use their bodies to the full again. Question: What is the author's intention of writing this passage? - to introduce an interesting and advanced study - to inform us of the latest development of virtual reality - to illustrate the importance of virtual reality - to build up our confidence to fight stroke
A: to introduce an interesting and advanced study
