World leaders from nearly 200 countries have signed an important historic agreement to fight global climate change. 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 (协定).

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(承诺)to limit the amount of greenhouse gases emitted(排放) 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. 60℉(20℃) 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 together to reduce man-made emissions.

“History will remember this day,” U. N. Secretary General Ban Ki-moon said. “The Paris agreement on climate change is a monumental success for the planet and its people.”

2.According to the agreement, countries_________ .

A. have to give a yearly report about their work

B. will be published if they fail to reduce pollution

C. are required to ensure investment in fighting pollution

D. should try to reach the agreed standard in five years

Deliberately making a road icy sounds like a method for disaster, but in 16th-century China it helped things run smoothly. Repairs to the Forbidden City in Beijing in 1557 called for huge stones from a quarry(采石场) more than 70 km away. The biggest was the 300-ton “Large Stone Carving.” Such stones were too heavy for any cart, and too fragile for rollers. The builders adopted a wise alternative approach to carry the heavy stone.

They dug a series of wells, spaced a few hundred metres apart, along the route to the quarry. Then, in the depth of winter, when temperatures reached around -4℃, buckets of water were poured on to the dirt track, transforming it into an ice road.

The stone blocks were pushed along the road on wooden sledges (雪橇). Modern engineers have calculated that it would take 1,500 workers to drag a sledge on the dirt road, but only 300 on ice. Ancient tests suggested the ice was made slippery with more water; this reduced the friction further and just 50 men could pull a sledge. This technique only works when the temperature is also close to zero, otherwise the film of water freezes too quickly.

The researchers at Princeton University estimated that the blocks could be moved at six metres a minute, and the journey could be completed in 28 days. This would be well before the spring when the ice would melt.

It was once suggested that similar ice-sledges transported Stonehenge stones, but the ground that had a lot of holes and comparatively mild conditions probably rule this out.

1.Why did people dig some wells along the road to the quarry?

A. They wanted to build frozen roads.

B. They wanted to break up large stones.

C. They wanted to make the dirty track clean.

D. They wanted to get a lot of holes on the road.

2.What did people do to reduce the friction?

A. They made stone blocks much smaller.

B. They poured more water on the ice road.

C. They waited until the temperature was very low.

D. They asked more than 1,500 workers to clean the dirty road.

3.How did the researchers at Princeton University think of Stonehenge stones?

A. They were not likely to be carried on the icy road.

B. They had a longer history than stones in Beijing.

C. They were carried for over twenty-eight days.

D. They were broken up in the depth of winter.

4.What does the author intend to tell us in the text?

A. Making a road slippery on purpose may be bad idea.

B. The mild weather helped to carry Stonehenge stones.

C. Stonehenge stones were too heavy to carry.

D. Ancient Chinese transported huge stones wisely.

A short guide to surviving a post-election Thanksgiving

Thanksgiving in the US is a celebration of the blessings of the previous year. This time it included one of the most divisive presidential campaigns. Even now it is over, the possibility of argument has not disappeared. Here we have some tips for you to survive this Thanksgiving.

●Cover up any signal of union

It might be fine to have your Hillary bumper sticker in New York, but it isn't going to go down well in Wyoming, where 70% voted Trump. Similarly, your "I love Trump" T-shirt will probably not be popular in California, where 62% voted Hillary.1.

●Practice your facial expression beforehand

They say a picture tells 1,000 words. Your face is the same. 2.You need to invest some energy in making sure your true feelings are completely buried. Ten minutes in front of the mirror should be enough to perfect your neutral face. 3.Well, we suggest closing them. Easy.

●Have a list of neutral topics for the dinner table

The weather is A favorite subject of the British. It is inoffensive, bland and can provide a good half-hour's chat, if done well. Everyone has an opinion on whether or not it is colder/hotter/wetter/windier than last year/10 years ago/when they were little. You can involve the whole family.4.With Clinton and Trump supporters largely split on whether climate change exists, it could inadvertently lead to politics. So it's maybe trickier for Americans than the weather-worn Brits. 5.After all, the rivalry between your American football team of choice and your cousin's may have a long and vitriolic history, but it is likely to be less poisonous than the current differences in your politics.

A. Sports may not be a neutral subject.

B. Biting your lip is simply not enough this holiday season.

C. There are hundreds of outstanding topics for Thanksgiving.

D. There is one slight downfall to this particular favorite.

E. Are you one of those people whose eyes always tell the truth?

F. So we advise leaving the T-shirt at home, and covering up the stickers.

G. It would be fine, if people of different opinions would not spend Thanksgiving together.

How long can you safely freeze food?

Frozen food lasts indefinitely. But does that mean the raw chicken you bought on sale and froze will taste as good a year from now as it will three weeks from now?

Fruits and vegetables.

You can freeze most vegetables and non-citrus fruits for about 8 to 12 months, according to the National Center for Home Food Preservation. (You can freeze citrus, too, but you need to take some extra steps.) Vegetables will benefit from blanching(用沸水烫)before you freeze them. 2., which affects nutrient levels and appearance of your veggies.

3.

●Ground beef, turkey, veal, pork and lamb: For best flavor and texture, these ground meats are best used within three or four months of being frozen.

●Steaks and chops: These cuts of beef, veal, lamb or pork can be frozen for six to 12 months before losing quality. Chops of these meats start to lose quality after four to six months.

●Poultry: 4. ; pieces of birds keep their quality for up to nine months.

●Fish: For best quality, fatty fish (salmon, tuna) should be consumed within two to three months. Lean fish (cod, flounder) should be consumed within six months.
