【解析】

這是一篇說(shuō)明文。漁業(yè)和海洋部門已經(jīng)制定了約翰斯通海峽觀鯨的指導(dǎo)方針，每年夏天在那里每天都能發(fā)現(xiàn)虎鯨。短文介紹了船只經(jīng)營(yíng)者對(duì)所有種類的鯨魚必須遵守的操作規(guī)則。

【1】推理判斷題。根據(jù)第一段最后一句話It is strongly recommended that vessel(船只) operators follow these guidelines for all kinds of whales．可知，這些對(duì)各種各樣的鯨都必須遵守的操作規(guī)則被強(qiáng)烈地推薦給船只操作員。由此判斷出文章是寫給船只操作員的。故選C項(xiàng)。

【2】細(xì)節(jié)理解題。從操作規(guī)則第四、五條“Start your boat only after the whales are more than 100 meters from your vessel．Leave the area slowly, gradually moving faster when you are more than 300 meters from the whales”可知：在一百米之外，才能啟動(dòng)船只；三百米之外，才逐漸加速。所以離開觀測(cè)區(qū)域時(shí)，應(yīng)逐漸加快航速。故選B項(xiàng)。

【3】細(xì)節(jié)理解題。根據(jù)操作規(guī)則第八條Keep at low speeds and remain in the same direction if travelling side by side with whales．可知：當(dāng)船只和鯨并排前進(jìn)時(shí)，保持低速且應(yīng)同一個(gè)方向前進(jìn)。故選A項(xiàng)。

【4】細(xì)節(jié)理解題。根據(jù)從操作規(guī)則第二條Approach no closer than 100 meters, then stop the boat but keep the engine on．可知：靠近鯨不能低于一百米，然后停止，但要讓發(fā)動(dòng)機(jī)開著。所以最近的安全觀察距離應(yīng)是100米。故選D項(xiàng)。

【題目】Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.

I used to hate waiting in line, thinking of it as a big waste of time and a test on my patience, but 【1】(live) in Israel for three years, I have changed my attitude toward it.

Probably because the country is not very big, with limited resources, 【2】 you’re at the bank, the post office or the bus stop, you’ll always find a straight line of people waiting. But instead of worrying or hurrying some are drinking hot coffee; 【3】 are chatting to each other, even though a minute ago they were just strangers.

【4】 seemed to me that they were enjoying queuing and taking the chance to relax.

Gradually I came to realize that 【5】 (obey) rules, which can be clearly seen in queuing up, is an important part of their culture. Once I saw a young foreigner trying to jump the queue and be shouted at by an old Israeli man, with others joining in. The poor guy was so ashamed【6】 he slipped away as fast as he could.

But don’t think Israeli people are cruel. If you have to leave for a short time, 【7】 the person behind you agrees, you can always come back and stand in front of him or her. However, if you miss him or her, you’ll have to start over. If you wait next to the basketball court or tennis court for more than five minutes, someone on the court will definitely offer 【8】(switch) places with you. This has become part of the culture in Israel.

Their culture 【9】 (reflect) Israelis’ belief in equal opportunities, which may have played a role in helping Israel to stay on its feet in the world even after the cruel Holocaust.

Compared 【10】 Israel, our way of queuing up is much more casual. People always go out of their way to get the “privilege” of a shorter wait.

Holidays are not necessarily for fun or rest. Doing something meaningful can also gain special pleasure. When the final bell rang, the students were reminded that there was no school on Monday—the Labor Day. “Enjoy your extra day off,”said the teacher to her class.

An extra day of fun suited Kayla just fine. She loved breaks. She wanted to go out to play with her friends. When the school bus dropped Kayla off, she ran into the house happily.

“How was school, Kayla?” asked her mom.

“It was great, Mom. I am excited about no school on Monday. ”

“You just started back to school two weeks ago. Already in need of a break, huh?” asked Kayla’s mom with a laugh.

Kayla slept in the next morning. Saturday was her favorite day of the week. It rained most of the day, so Kayla enjoyed playing video games inside. On Sunday, her friends came over and they played basketball for several hours.

Then it was Labor Day, you know, the extra day off that Kayla was so looking forward to. But Kayla was awakened early that morning by her dad. He told Kayla that in honor of Labor Day, the family would be cleaning both inside and outside the house. Kayla couldn’t believe it. This was a holiday. A day when she was supposed to be enjoying freshly squeezed lemonade while playing in her tree house. As Kayla wiped her eyes, she began to wonder if this was just a bad dream.

“Kayla, your breakfast is ready. We have a lot of work to do today. Let’s get a move on, ”said Kayla’s mom. As she sat down at the kitchen table, Kayla asked her parents,

“Are you serious about working today? Isn’t Labor Day a holiday?”

“Yes, Kayla. It is, ”replied her dad. “But your mom and I thought working hard today would make you appreciate why Labor Day was observed in the first place. ”

Paragraph1：

At first, Kayla felt disappointed at her parents’ plan for the holiday.

【題目】 If you want to live longer, live around green space.

That’s the simple conclusion of the largest analysis ever performed on the relationship between the environment and human health—ever. Eight million people. Seven countries. One simple finding:

“When you are exposed to greenery or greenness around your home, your probability to die is less compared to those with less greenness around their home,” says David Rojas, researcher at the Barcelona Institute for Global Health. And he was the main author of the study, which was published in The Lancet Planet Health teaming up with the World Health Organization.

Specifically, the research team found that for every 10% increase in plants cover that’s within 1,600 feet of your home, your probability of death drops by 4%.

Those hard numbers are the result of a large metastudy(元研究) analyzing nine separate studies about longevity and green space that looked at how and how long people lived over long periods of time. Subjects were from countries around the globe, too: Australia, Canada, China, Spain, Italy, Switzerland, and the U. S.

As Rojas explained, in every country, the finding was the same. People who lived near more green space lived longer than people who lived near less. This green space can be grass, trees, or gardens. It can be public or private space.

He also explained, The study didn’t discriminate(歧視), nor did it have the accurate data to show that some plants were better for our health than others.

【1】Who carried out this research?

A.Rojas’ team

B.Rojas’ team and Lancet Planet Health

C.World Health Organization and Lancet Planet Health

D.Rojas’ team and World Health Organization

【2】What does the underlined word “l(fā)ongevity” in Paragraph 5 probably mean?

A.the length of lifeB.the balance of life

C.the strength of lifeD.the quality of life

【3】It can be inferred from the passage that .

A.Gardens are better for our health than grass and trees.

B.People who are surrounded with plants are probable to live longer.

C.For every 10% reducing in plants cover, your probability of death will increase by 4%.

D.People from developed countries with more green space live healthier than those in the developing countries.
