3 . The earth is dying before us, yet we sit and watch. If the TV or the game system breaks, we run off to the stores to get it fixed immediately no matter what the cost. Why aren’t we willing to fix our earth? Are our televisions and game systems more important to us than where we live? Where shall we continue to live, until the end of time?

The earth is our home and cannot be replaced. We must take care of it. We have come up with so much technology that limits us instead of helping us. Take that game system we run to repair. What does it do? It occupies kids’ time! The earth has already given kids plenty of entertainment in the forms of fields and hills, forests and plains, water and land. However, instead of using what the earth has given us, and helping kids by giving them exercise as they run around, we decide to ruin kids’ minds with game systems that glue them to the screen for hours, and make them ignore their homework and chores. We have polluted this earth by making these things which do not even help in any way!

We have already messed up this world, we have ruined the air, water, and animals that it has so willingly provided for us. We need to stop this destruction of life and bring back the world we had before. It will not be easy, but everybody can help! What about something as simple as turning the lights off when you leave a room? Recycling what can be recycled? Picking up litter? Donating money to an environmental organization? None of these things are very hard. We can’t just always say, “Oh, the earth is a mess. Ah, well, those big companies that are polluting so much can stop and fix it.” Instead, we need to help out. It’s not only those big companies; it’s everyday things that we do too that are ruining the earth. So, stop and think about what you can do to make a difference to our world!

4 . 阅读下面材料，在空白处填入1个适当的单词或括号内单词的正确形式。

A small town in England is teaching the world that it is important     1    (grow) your own food. Any open space     2    (use) to grow fruit and vegetables. There are apples, pears, peaches, strawberries, cabbages and carrots, here and there. Everyone can pick them     3     free. Eight years ago, a woman named Pam in Todmorden dug up her rose garden. She planted vegetables, knocked down the garden wall and put up a sign     4    (say), “Help yourself?” Today, Pam has     5    (complete) changed the town. A new town has been born,     6     is called “Incredible Edible Todmorden”. Pam explained why she thought the idea was popular. “It’s possible and positive. Many people know we have to change,     7     how we do that is a question. So one day, she gathered all the     8    (villager) together. They decided to do something different at once. They didn’t write reports. They didn’t ask for permission. They just did it. Only a short time     9    (late), Todmorden became a big garden of fruit vegetables. In Todmorden, there is a motto: If you eat, you are in. But that’s not all. There are     10    (many) than 700 edible towns popping up around the world, from Canada to Mali. People there think about food and protect environment at the same time.

5 . For some people, walking or running outdoors is a great way to exercise. What may not be so great is seeing rubbish all over the ground. Well, some people are doing something about it.     1     “Plogging” began in Sweden. The name connects the Swedish word “plocka,” which means to pick up, and the word “jogging,” which means to run slowly.

A Swedish man named Erik Ahlström, started the movement in 2016. He moved to Stockholm from a small community (社区) in northern Sweden. Each day he would ride his bike to work. He became worried about the amount of rubbish and litter he saw each day on his way to work. So, he took matters into his own hands. He began picking up the rubbish.     2    

Today, plogging is an official activity, which is becoming more and more popular. People of all ages are welcome to plog. Exercise while helping your community.     3     It can also build closer social connections in a community. When the street looks bad and it’s dirty, you're going to feel bad about the community. You may even feel less safe because of that. So if we’re all doing our part and picking it up, it’s very easy to help beautify it, and help build those social connection.     4     You get to feel some social duty when you do this.

Along with cleaning up the environment, there may be another reason to choose plogging instead of just jogging. You may get a better workout. One fitness app, Lifesum, records one hour of plogging as burning 288 calories.     5    

As can be seen, cities around the world now hold plogging events. The goal is to spread the idea that littering is not acceptable. People would think twice before dropping a garbage on the ground.

A．Plogging is equal parts of exercise and community service.

B．And that is how plogging was born!

C．And plogging does good to your health.

D．Usual jogging burns about 235 calories.

E．They are plogging!

F．There are people all around the world doing this.

G．You get to know your neighbors.

6 . Since the sex of a sea turtle(海龟)is determined by the heat of sand hatching the eggs, scientists had suspected they might see slightly more females. Climate change, after all, has driven sea temperatures higher, which, in these creatures, favors female children. They found female sea turtles from Raine Island, the Pacific Ocean's largest and most important green sea turtle living area, now outnumber males by at least 116 to 1. "This is extreme," says turtle scientist Camryn Allen.

Biologist Michael Jensen wanted to know if climate change had already changed turtles' sexes. By using genetic(基因的) tests, he'd figured out that he could follow turtles of all ages. Still, his research data would lack an important detail: sex. Only after a turtle matures is it possible to tell its sex from the outside -- mature males have slightly longer tails. By then turtles can be decades old, so scientists often use Iaparoscopy(腹腔镜检查)，sending a thin tube into each animal, but that's not so practical if you're hoping to examine hundreds of creatures. Fortunately, at a turtle conference, he met Allen, and all she needed was a little blood.

They compared their results with temperature data for nesting beaches. What worries them is that Raine Island has been producing almost female turtles for at least 20 years. This is no small thing. More than 200,000 turtles come to nest there. During high season, 18,000 turtles may settle in at once. "But what happens in 20 years when there are no more males coming up as adults? Are there enough to maintain the population?" says Allen. They also found cooler beaches in the south are still producing males, but that in the north, it's almost entirely females hatching. These findings clearly point to the fact that climate change is changing many aspects of wildlife biology.

But how widespread is this phenomenon -- and what is the consequence?

1. How might the scientists feel if there were slightly more female turtles?

A．It's normal.

B．It's unique.

C．It's extreme.

D．It's doubtful.

2. What is a scientist's conventional way to identify a turtle's sex?

A．Testing its blood.	B．Doing genetic tests.
C．Using laparoscopy.	D．Watching its tail.

3. Why do the findings worry Jensen and Allen?

A．Too many females gather near Raine Island.	B．Sea turtles may end up dying out.
C．Turtle populations are in decline.	D．Female turtles cause temperatures to rise.

4. What does the last paragraph imply?

A．People should stop the phenomenon.

B．People have to test the consequence.

C．Climate change has changed sea turtles' sexes.

D．More work needs doing about the phenomenon.
