Do you love holidays but hate the increase weight that follows? You are not alone. Holidays are happy days with pleasure and delicious foods. Many people, however, are worried about the weight that comes along with these delicious foods.

With proper planning, though, it is possible to control your weight. The idea is to enjoy the holidays but not to eat too much. You don't have to turn away from the foods that you enjoy. The following suggestions may be of some help to you.

Do not miss meals. Before yon leave home for a feast(宴會),have a small, low-fat snack(小吃). This may help to keep you from getting too excited before delicious foods. Begin with clear soup and fruit or vegetables. A large glass of water before you eat may help you feel full. Use a small plate; a large plate will encourage you to have more than enough. Better not have high-fat foods. Dishes that look oily or creamy have much fat in them. Choose lean meat(瘦肉 ).Fill your plate with salad and green vegetables. If you have a sweet tooth, try mints (薄荷) and fruits. They don’t have fat content as cream and chocolate.

Don’t let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess(過多的) calories.

1. Holidays are happy days with pleasure but they may ______

Mountaineers have noted that as they climb, for example, up to the 12,633?foot Humphreys Peak in Arizona, plant life changes greatly. In the Sonoran Desert, one climbs into a pine forest at 7,000 feet and a treeless tundra(凍土帶) on the top of the mountain. It may seem that plants at a given altitude are associated in what can be called “communities” －groupings of species. The idea is that over time, plants that require particular climate and soil conditions come to live in the same places, and are frequently to be found together. Scientists study the history of plant life and build up a picture of how groups of plants have responded to climate changes and how ecosystems develop. But are these associations, which are real in the present, permanent?

A great natural experiment took place on this planet between 25,000 and 10,000 years ago, when small changes in the earth’s orbit caused great sheets of ice to spread from poles. These glaciers(冰川) covered much of North America and Europe to depths of up to two miles, and then, as the climate warmed, they retreated. During this retreat, they left behind newly uncovered land for living things to occupy, and as those living things moved in they laid down a record we can read now. As the ice retreated and plants started to grow near a lake, they release pollen(花粉). Some would fall into the lake, sink to the bottom and mix with the sand. By drilling into the lake bottom it is possible to read the record of the plant life around the lake. The fossil record seems clear; there is little or no evidence that entire groups of plants moved north together. Things that lived together in the past don’t live together now, and things that live together now didn’t live together in the past. Each individual living things moved at its own pace. The fossil record seems to be telling us that we should be thinking about preserving species by giving them room to move about－to respond to environmental changes.

1.According to the passage, the movement of individual species of plants ________.

A. occurs in groups

B. often depends upon the formation of lakes

C. does not occur in groups

D. depends upon climate and soil conditions

2. All of the following are true EXCEPT ________.

A. The ice age occurred when there were small changes in the orbit of the earth

B. fossil records seem to indicate that plants will be preserved if they have enough room to move

C. fossil records clearly show that entire groups of plants are unlikely to have moved together

D. in the ice age glaciers covered the world to depths of up to two miles

3.The underlined word “which” refers to ________.

A. the responses of plants to climate changes

B. the current theories of ecosystems

C. the development of ecosystems

D. plant life changes

4.The second paragraph is intended to ________.

A. support the main idea of the first paragraph

B. answer the question raised in first paragraph

C. make suggestions about responding to environmental changes

D. stress the importance of preserving species

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 (協(xié)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（承諾）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.”

1.When was the legal pact probably passed?

A. On November 30. B. On December 4.

C. On December 8. D. On December 12.

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

3.What is each country required to do before the Paris conference?

A. Provide a work plan. B. Give an oral explanation.

C. Provide a large amount of money. D. Give a written assessment.

4.The pact is thought to be imperfect because_______.

A. it doesn’t consider developing countries

B. it is not detailed enough

C. it is not attractive to all countries

D. it only benefits some countries
