根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Usually summer break provides teens with an opportunity to get away from the boring life of going to school, to visit friends and have fun with them, and to make a little extra money. The summer job market for teens can be highly competitive. Half-heartedly (不认真地）looking for a job is the quickest way to get turned down over and over. 1.

2. Look at the skills required for each. Then compare these skills with those you already have. The closer the match, the more likely you will enjoy your summer job while building a good reference for future jobs.

Understanding why you want to work will also help you determine where to apply. Do you want to earn extra money for something special, or do you need the job to make ends meet? 3. These are just a few of the questions you need to answer before starting your job search.

When you’re searching for a summer job, look for help beyond the wanted signs. 4. And even if a business doesn’t have a sign or advertisement indicating that they are looking for help, stop by and ask a manager. You might fill in an application anyway, which could lead to a position in the future.

5. Ice cream shops, restaurants, grocery stores and movie theaters commonly hire students. You might take a job that has less desirable hours or that you don’t necessarily enjoy. However, summer jobs don’t last forever. You can still build your skills and experience while making money.

A. Here are some tips on finding summer jobs.

B. Take time to think about the types of jobs that are suitable for you.

C. Be flexible and creative when you’re looking for a summer job.

D. If you are poor in math, you probably would lose your job.

E. Let your family, neighbors and teachers know that you’re looking for a job.

F. A good attitude towards work sometimes can make up for lack of skills.

G. Are you looking for a job where your friends work, so you can be with them?

Elephants have impressed us for centuries. They are big, clever, and sociable. But what if someone told you that they may also hold the key to fighting cancer?

People have been wondering why elephants do not develop cancer, even though they have life spans（寿命）that are similar to humans, living for around 50 to 70 years.

Now scientists believe they know why. A team at the University of Chicago, Us has found that elephants carry a large number of genes that stop tumors（肿瘤）from developing. To be precise, they found 20 copies of an anti-tumor gene called TP 53 in elephants. Most other species, humans included, only carry one copy.

According to the research, which was recently published on the online science network BioRxiv, the extra copies of the gene improved the animal’s sensitivity to DNA damage. This lets the cells（细胞）quickly kill themselves when damaged before they can form deadly tumors.

“An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals,” study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous, large creatures with long life spans like whales and elephants should have a greater risk of developing cancer than humans and mice do. But across species, the risk of cancer does not show a connection with body mass.

This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named “Peto’s paradox”. Evolutionary biologists believe it results from larger animals using protection that many smaller do not, In the elephant’s case, the making of TP53 is nature’s way of keeping this species alive.

The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers from spreading or even developing in the first place.

“Nature has already figured out how to prevent cancer,” said Joshua Schiffman, an oncologist at the School of Medicine, University of Utah, US.

“It’s up to us to learn how different animals tackle（对付）the problem so we can use those strategies to prevent cancer in people.”

1.Why are elephants unlikely to develop cancer?

A. They have a large body size

B. They carry many genes that keep tumors from developing

C. Certain genes in their body kill existing tumors

D. Their genes suffer no DNA damage

2.According to Dr. Vincent Lynch, what has been a risk in the evolution of large animals?

A. Extreme weather B. Cells killing themselves

C. Human behavior D. A risk of deadly tumors

3.What does the underlined expression “this phenomenon” on the sixth paragraph refer to?

A. The risk of cancer is not related to body size

B. Larger animals have protection from TP53

C. Larger animals suffer the same risk of cancer as smaller ones do

D. The larger animals are, the bigger risk of cancer they have

4.We can conclude from the last three paragraphs that .

A. depending on nature is not enough to fight against cancer

B. the TP53 genes have proven useful in stopping cancer in mice

C. this new treatment is more effective than the present ones

D. humans are expected to stop cancer in the near future

Owls(猫头鹰) are mysterious creatures. We often think of them as scary. They sometimes live in abandoned houses. They fly without a sound through backyards at night. In stories, they appear with ghosts. When we hear an owl's familiar “wh?ooo...whooo...”，it can make us feel very frightened. Owls fly silently, without even a whisper of wings moving through the air. It's as though they appear out of nowhere—like ghosts on wings. Owls fly and hunt on the darkest of nights. An owl's night habits make it unique. Do these creatures of the night possess strange powers?

Owls possess unusual powers of sight and hearing, but they are not supernatural powers. They are natural adaptations that let them live most efficiently(高效地) at night. There is no reason to fear owls. Their habits make them helpful to humans. By hunting mice and other rodents(啮齿目动物)，owls help to keep a natural balance between plant and animal life. Without owls, there would be a large number of rodents in farmers' fields and storage barns.

More than 100 species of owls occupy a variety of habitats around the world. A few oceanic islands and the Antarctic have no owls. The world's owls come in different sizes. For example, the Eurasian eagle owl—one of the largest—has a body that is two to three feet long, with a wingspan(翼展) of up to five and one?half feet. The North American elf owl (the world's smallest owl) is five to six inches long and has a wingspan that measures slightly more than one foot.

Most male and female owls of the same species look alike, although females are usually larger. In some species, the female's colors are like those of the trees or grass where she makes her nest.

Baby owls, called chicks, stay with their parents until they are about three months old. They soon find their own hunting areas, where they may stay for the rest of their lives. Some owls can live 20 years or more.

1.Most people regard owls as________.

A．clever B．hard?working C．shy D．terrifying

2.Owls help humans in that they________.

A．frighten rodents away from humans

B．help preserve the balance of nature

C．have unusual powers

D．help guard backyards

3.What is special about owls?

A．They fly silently.

B．They are night hunters.

C．They possess supernatural powers.

D．They can be found around the world.

A. was suggesting B.will suggest

C. would suggest D. had suggested

One day a woodcutter took his grandson into the forest for his first experience of selecting and cutting oak trees. They would later _________ them to the boat builders.
