The Most Important Reading Comprehension Part 102

In the realm of language education, honing reading comprehension skills is paramount for learners of all levels. From comprehension passages tailored for different classes to learning comprehension strategies, the journey begins with engaging English materials. For instance, comprehension for class 1, class 2, and class 3 introduces foundational skills, gradually progressing as students advance through their academic journey. Incorporating unseen passages into the curriculum, especially for class 2, class 3, and class 7, challenges students to apply their understanding to unfamiliar texts.

The significance of reading comprehension exercises cannot be overstated; they serve as the linchpin for developing a strong command of the language. To further enhance this, leveraging reading comprehension practice becomes essential. This practice, coupled with a variety of comprehension passages, ensures that learners encounter diverse topics and genres, fostering a well-rounded proficiency in both comprehension and language comprehension skills.

Furthermore, including english passages and prose comprehension in the curriculum broadens the scope of literary exploration. These not only offer exposure to various writing styles but also deepen students’ appreciation for the intricacies of language. Whether it’s an unseen passage for class 4, class 6, or class 7, each reading exercise contributes to the holistic development of language comprehension skills.

In conclusion, the integration of reading comprehension into educational frameworks is fundamental for nurturing language proficiency. By incorporating comprehension passages across different classes, providing tailored comprehension for class 1, class 2, and class 3, and embracing diverse unseen passages, educators lay the foundation for students to navigate the intricate landscape of language with confidence and competence.

Scientists have developed a new cancer drug. So far, they have tested it only in laboratory animals. The drug is designed to invade and kill cancer cells but not healthy cells.

First, the drug enters the cancer and destroys the supply of blood. Then it releases poison to destroy the cancer cells.

Researchers at the Massachusetts Institute of Technology in Cambridge carried out the study. The results appeared in Nature magazine. A school news release called the drug an “anti-cancer smart bomb.”

Ram Sasisekharan is a professor at M.I.T. He says his team had to solve three problems. They had to find a way to destroy the blood vessels, then to prevent the growth of new ones. But they also needed the blood vessels to supply chemicals to destroy the cancer.

So, the researchers designed a two-part “nanocell.” The cell is measured in nanometers, or one thousand-millionth of a meter. The particle used was two hundred nanometers — much, much smaller than a human hair.

The scientists say it was small enough to pass through the blood vessels of the cancer. But it was too big to enter normal blood vessels. The surface of the nanocells also helped them to avoid natural defenses.

The scientists designed the cell as a balloon inside a balloon. They loaded the outer part with a drug that caused the blood vessels to fall in on themselves. That cut off the blood supply and trapped the nanocell inside the cancer. Then, the nanocell slowly released chemotherapy drugs to kill the cancer cells.

The team says the treatment shrank the cancer and avoided healthy cells better than other treatments. Untreated mice with cancer survived for twenty days. The scientists say mice with the best current treatments lived thirty days. But they say eighty percent of the mice treated with the nanocells lived more than sixty-five days.

The study involved two different forms of cancer. The team says the treatment worked better against melanoma, a deadly skin cancer, than against lung cancer. However, more studies are needed before the new drug can be tested in humans.

Scientists at the Massachusetts Institute of Technology (M.I.T.) have developed a new cancer drug designed to invade and kill cancer cells while sparing healthy cells. What is the unique feature of this drug, according to the researchers? a) It directly targets the DNA of cancer cells b) It destroys the blood vessels supplying the cancer cells c) It stimulates the immune system to fight cancer	1
What is the size of the “nanocell” used in the study, and why was this size crucial for its effectiveness? a) 2 centimeters; it needed to reach deep tumors b) 200 micrometers; it needed to release a large drug payload c) 200 nanometers; it was small enough to pass through cancer blood vessels but too large for normal vessels	2
The researchers describe the nanocell as a “balloon inside a balloon.” What is the purpose of this design? a) To make the nanocell visually appealing b) To create a barrier against cancer growth c) To load the outer part with a drug that causes blood vessels to collapse	3
In the study involving mice with cancer, what was the survival outcome for untreated mice, mice treated with the best current treatments, and mice treated with nanocells? a) Untreated: 20 days; Current treatments: 30 days; Nanocells: >65 days b) Untreated: 15 days; Current treatments: 25 days; Nanocells: >60 days c) Untreated: 25 days; Current treatments: 35 days; Nanocells: >70 days	4
Which type of cancer showed a better response to the nanocell treatment in the study? a) Lung cancer b) Melanoma (skin cancer) c) Breast cancer	5
