1 . You might not expect it, but cows are a large source of the greenhouse gases that are driving climate change. Cows produce lots of methane by breaking down the grass, Now scientists have shown that the pollution from cows can be reduced by adding a little seaweed to their food.

Scientists first discovered that seaweed could help control methane from cows several years ago. But this work was done in a laboratory, there were many questions about whether the idea could work in real life.

In the lab studies, the cows were given quite a bit of seaweed, and they would cause losing weight. That wasn't helpful, since cows are often sold by weight. It also wasn't clear if the seaweed would stop working if it was used for a longer period of time.

Now, scientists from the University of California, Davis have answered several of these questions.

The researchers studied 21 cows on a farm for about five months. They taught the cows to get their food from inside a special hood, which allowed the scientists to measure the methane that the cows were giving off. This time, they used a much smaller amount of seaweed, which they mixed with the cows' food.

The results were surprisingly good. In some cases, the cows produced 82% less methane. The improvement depended on the kind of food the cows were given, but even the worst-polluting cows produced 33% less methane.

Over the five months, the scientists didn't see any signs that the cows' stomachs were getting used to the seaweed and starting to produce more methane again.

Another surprise came when they looked at the weight of the cows. The cows that were fed seaweed gained just as much weight as the other cows, but they didn't need as much food.

But there are still some big problems with the idea of feeding cows seaweed. For one thing, there's not adequate seaweed to feed all of the cows in the world. So farmers would have to figure out a way to grow lots of seaweed.

A bigger problem is that for most of their lives, cows live in fields, where they eat the grass. That means there's no chance to feed them seaweed every day. These problems need to be taken seriously if the world is going to avoid the worst effects of the climate crisis.

Still, it's true that something as simple as feeding cows seaweed can help reduce some of the pollution causing the climate crisis.

1. Why did the scientists do the experiment on the farm?
A.To control the amount of seaweed.B.To record the weight cows gained.
C.To confirm the effect of seaweed in real life.D.To measure the amount of seaweed cows ale.
2. The underlined word “adequate” means ________ .
A.commonB.specialC.lackingD.enough
3. The passage is written to ________ .
A.appeal to people not to raise the cowsB.encourage people to plant the seaweed
C.remind people of controlling cows' weightD.call on people to take actions to reduce the pollution

Spending almost a full day in the car with a 74-year-old woman could be boring for a 16-year-old high school student. For me, though, this was the best way to end 2020 and begin the New Year.

She valued the wisdom that I had from my 16 years; I learned a lot I never expected to. I     3     (understand) the importance of real conversation. I knew that you shouldn't take yourself too seriously and that not everyone had to get "old and boring".

5 . 阅读下面短文,根据题目要求回答问题。

Last week, the United Nations (UN) released the most complete report ever created on the global problem of food waste. It found that the world wastes about 17% of all the food produced. That's about a billion tons of food a year.

A billion tons is a lot of food — it's over 2 trillion (2 ,000 ,000 ,000 ,000) pounds or about 931 billion (931 ,000 ,000 ,000) kilograms. The report says that the amount wasted is roughly twice as much as earlier studies had suggested.

The report was produced by the UN's Environment Program (UNEP) and covered food waste around the world in 2019. The study showed a several different ways in which food was wasted — at home, in restaurants and in stores.

It turns out that by far, most food waste — about 61% — happens horse. On average, the amount of food thrown out at home works out to about 163 pounds (74 kilograms) for each person every year.

Restaurants were responsible for about 26% of the food wasted. The remaining 13% was thrown away by stores.

Many people thought rich countries were more likely to waste food than countries that were less rich. That turned out not to be true. One surprising discovery was that food was wasted at about the same rate in all but the poorest countries. (The UN had difficulty measuring food waste in the poorest countries.)

But people in richer countries may waste less food at home because they are eating out at restaurants more often. That certainly seems to be the case in the US, which has low waste numbers for homes, but quite high numbers for restaurants.

In some cases, labels might be causing food waste, the report said. People might be throwing away food even though it's still good to eat, simply because the container's "Best By" or "Sell By" date has passed. In poorer countries, food may be wasted because not all homes have a refrigerator.

Why is wasting food such a problem? For one thing, the report points out, hundreds of millions of people went hungry in 2019. Also, wasting food is really bad for the planet. Farming creates between 10% and 30% of the world's greenhouse gas emissions (排放) — the pollution that's making the climate crisis worse. So when food gets thrown out, the pollution is created for nothing.

The UNEP report says that it's important for countries to study food waste more carefully in order to figure out ways to solve the problem.

1. How many tons of food are wasted a year according to the UN report?
2. Why is wasting food bad for the environment?
3. Read the following statement, underline the false part of it and explain the reason.
Labels might be causing food waste, because people might be throwing away food that is bad to eat.
4. Please briefly present what you can do in daily life to save food. (about 40 words)

6 . Maintaining and Building Muscle

Staying healthy is very important, but eating well and getting active is only part of the story. Often, we forget how important it is to concentrate on building and maintaining our muscles.

    1     It can also help you improve your immune system, speed up your body's healing process, and let you sleep better. And as you age, the muscles you've developed will help you with your balance, bone strength, posture, and even more confident.     2     After all, you don't have to look like Arnold Schwarzenegger to feel good about being a bit stronger!

With all these great reasons for strength training, there are also so many myths that stop women from doing it.     3     The truth is, since women have about one-fifteenth the testosterone of men, it's much harder for them to get big muscles than it is for men. So go ahead ladies, get stronger. You'll be happy you did!

There are some easy ways to build muscle at home.     4     But did you know that, when done right, push-ups can be as effective as weight lifting? The trick is to make sure you are constantly varying the type of push-up. Placing your hands closer together or further apart are two excellent ways to isolate different muscle groups and ensure you get the maximum return on your effort.

    5     For example, squats and lunges for your legs, pull-ups and chin-ups for your upper body, and crunches and planks for your core. With every exercise, you should keep track of how many you do and measure your improvements over time. In addition, keep in mind that once a specific exercise gets too easy, there are always plenty of changes to help increase is difficulty.

There are so many strength training exercises that are simple, easy to do at home, and great for your health. Why not give them a try? Just remember: the hardest part is getting started!

A.Instead, they can try taking a bath o fall asleep.
B.People may fear it is a hard work to insist on strength training.
C.Of all the benefits, maybe the best part is your improved confidence.
D.Without leaving the comfort of your home, you are probably familiar with push-ups.
E.Building muscle strength does more than just help you lift heavier things and lose weight.
F.Women's common fear is that lifting weights will make them look too bulky.
G.There are also other simple ways to increase muscle strength.

7 . Henry Cavill: Bring Superman to Life

Henry Cavill knew that he wanted to be a star at 16 years of age, after a chance meeting with movie star Russell Crowe who inspired his passion for acting. But for the British-born actor, the bright lights and attraction of Hollywood were a long way away. Supported by his secretary mother and stockbroker father, he decided to study drama during high school. His journey to super star began.


Before gaining the international recognition he has now, Cavill tried out for roles in the Harry Potter and Twilight series but failed to get either. He would have to keep waiting for his big chance.

Determined as ever, Cavill took any acting jobs he could get his hands on and appeared in several low-budget horror movies and TV shows in hopes of getting noticed. It almost worked. In the early 2000s, at just 22 years old, he narrowly missed out on becoming the new James Bond. Finally, in 2007, his hard work paid off. He won a leading role as the first Duke of Suffolk in the period show The Tudors. The TV show was very popular and helped to raise Cavill's popularity in America.

In 2011, Cavil landed his breakout role, playing Superman in the DC Extended Universe. He hasn't looked back and has since starred in many hit films, such as Mission: Impossible- Fallout.

More recently, he stepped back on to the small screen. Since 2019, he has starred in the popular series The Witcher, adapted from the book series and video games of the same name. In the TV show, Cavill played a brave monster hunter named Geralt of Rivia, which was the perfect role for Cavill because he was a fan of the video games. Cavill also got a chance to play a classic English character — master detective Sherlock Holmes — in 2020's Enola Holmes.

However, Cavill isn't just a good guy on screen. His charity work also makes him a real-life hero. In 2014, he took part in the Ice Bucket Challenge while wearing his full Superman suit to support the ALS Association. Currently, he is an ambassador for the UK's Royal Marines Charity, which supports war veterans (退伍军人). Why does he do it? He love to make people feel good and bring smiles to people' faces. Indeed, Henry Cavill in living proof that you don't always need to wear a cape (斗篷) to act like a hero.

1. Why did Cavil act in low-budget film and TV works early in his career?
A.He was too polite to refuse.
B.He was hoping to get noticed.
C.He was encouraged to do so by his parents.
D.He was friends with the directors of the projects.
2. The role of the monster hunter was the perfect for Cavill because ________ .
A.he had experienced hunting monsters
B.he had played the same role in a movie
C.he knew the writer of the books personally
D.he enjoyed the video games that the show was rooted in
3. Which of the following words can best describe Cavill?
A.Modest and friendly.B.Determined and kind.
C.Talented and faithful.D.Honest and considerate.
4. What made Cavill a real-life hero?
A.Being a successful actor.
B.Playing Superman on screen.
C.Devoting to charities.
D.Wearing a cape to take part in activities.
