Read the passage: Roman engineers built their roads in layers. At the bottom was a bed of large stones, then a layer of gravel and sand, and on top a surface of tightly fitted paving stones. The surface was raised slightly in the center so that rainwater ran off into ditches on either side. Because water is the great enemy of any road, this drainage did as much to keep the roads in use for centuries as the stones did. Which statement best expresses the central idea of the passage?

1. Read the passage: Roman engineers built their roads in layers. At the bottom was a bed of large stones, then a layer of gravel and sand, and on top a surface of tightly fitted paving stones. The surface was raised slightly in the center so that rainwater ran off into ditches on either side. Because water is the great enemy of any road, this drainage did as much to keep the roads in use for centuries as the stones did. Which statement best expresses the central idea of the passage?
- A. Roman roads were made of stone because stone was cheap.
- B. The paving stones were the most important layer of a Roman road.
- C. Roman roads lasted because of how they were layered and how they shed water.
- D. Roman engineers built roads mainly to protect the army from rain.
Voir la réponse et l'explication
Réponse : C. Roman roads lasted because of how they were layered and how they shed water.
A central idea has to cover the whole passage: the layers and the drainage, and why both mattered. The paving stone option ignores the last sentence, which says drainage did as much as the stones. Cost and the army are never mentioned.
2. Read the passage: Glaciers move slowly, but not steadily. A glacier may creep forward only a few inches in a day, then surge ahead dozens of feet after a season of heavy snowfall. This uneven movement makes it hard to predict where the ice will be in ten years. As used in the passage, surge most nearly means
- A. move forward suddenly
- B. slowly melt away
- C. split into pieces
- D. stop completely
Voir la réponse et l'explication
Réponse : A. move forward suddenly
The sentence sets surge against creep, a few inches in a day, so it must mean the opposite: a fast, sudden advance of dozens of feet. The last sentence confirms it by calling the movement uneven and hard to predict.
3. Read the passage: Ines had rehearsed the speech on the bus, in the shower and twice for the cat. But now that the gym was full, the page in her hand seemed to belong to a stranger. She looked at the first line, then at the back wall, then at her brother, who was holding up a crooked sign that said GO INES in marker. Her shoulders loosened. She cleared her throat and began with the one sentence she had not written down. Which inference about Ines is best supported by the passage?
- A. She was unprepared because she had never practiced out loud.
- B. Her brother wrote the speech she is about to give.
- C. She is angry that the gym is so crowded.
- D. Seeing her brother steadies her, and she begins in her own words.
Voir la réponse et l'explication
Réponse : D. Seeing her brother steadies her, and she begins in her own words.
Her shoulders loosen right after she sees the sign, and she then starts with a sentence she did not write down, so she is calmer and speaks for herself. The passage lists several places she rehearsed, and nothing says who wrote the speech or that she is angry.
4. Read the passage: Each autumn, monarch butterflies in eastern North America fly south to spend the winter in the mountains of central Mexico. The trip can cover more than a thousand miles. The butterflies that head north again in spring, however, are not the ones that made the trip south. The journey north takes several generations, and each one lays eggs and dies along the way. Which statements are supported by the passage? Select all that apply.

- A. Eastern monarchs spend the winter in the mountains of central Mexico.
- B. A single monarch flies the whole round trip each year.
- C. The trip back north takes more than one generation of butterflies.
- D. Monarchs fly south because food runs out in Mexico.
- E. The trip south can be more than a thousand miles long.
Voir la réponse et l'explication
Réponse : A. Eastern monarchs spend the winter in the mountains of central Mexico., C. The trip back north takes more than one generation of butterflies., E. The trip south can be more than a thousand miles long.
Three statements appear in the passage almost word for word. The round trip claim is contradicted, because the butterflies heading north are not the ones that went south, and the passage never gives a reason for the migration. Check every choice against the text, not against what you already know.
5. Read the sentence: The garden is tended by a different grade each week, the cafeteria serves the vegetables in its salad bar. Which version is punctuated correctly?
- A. The garden is tended by a different grade each week, the cafeteria serves the vegetables in its salad bar.
- B. The garden is tended by a different grade each week; the cafeteria serves the vegetables in its salad bar.
- C. The garden is tended by a different grade each week the cafeteria serves the vegetables in its salad bar.
- D. The garden is tended by a different grade each week, then the cafeteria serves the vegetables in its salad bar.
Voir la réponse et l'explication
Réponse : B. The garden is tended by a different grade each week; the cafeteria serves the vegetables in its salad bar.
The sentence is two complete thoughts, and a comma cannot join them, which is a comma splice. A semicolon can. Using no punctuation makes a run-on, and adding then after the comma still leaves two complete sentences joined by a comma alone.
6. Read the paragraph: (1) Last spring, students at Harbor Middle School planted a garden behind the gym. (2) Within months it had grown to eight raised beds, a compost bin and a rain barrel. (3) The principal's favorite food is pizza. (4) Students now sell extra vegetables at a stand every Friday. (5) The money pays for new seeds and tools. Which sentence should be deleted to keep the paragraph focused?
- A. Sentence 1
- B. Sentence 2
- C. Sentence 3
- D. Sentence 4
Voir la réponse et l'explication
Réponse : C. Sentence 3
Every other sentence is about the garden: where it started, how it grew, what happens to the vegetables and where the money goes. The principal's favorite food has nothing to do with the garden, so it breaks the focus.
7. Complete the sentence so the verb tenses stay consistent.
Students plant the seeds in spring and _____ the vegetables in fall, and the cafeteria _____ them in its salad bar.
Options pour le trou 1 : harvest, harvested, harvesting, to harvest
Options pour le trou 2 : serve, serves, served, serving
Voir la réponse et l'explication
Réponse : harvest, serves
The sentence is in the present tense, so the verb joined to plant must be harvest. The second blank needs a verb that agrees with the singular subject cafeteria, which is serves. The past tense would break the pattern, and an -ing form cannot stand alone as the verb.
8. Read the sentences: (1) The students planted a garden behind the gym. (2) They started with one raised bed. Which choice best combines them into one sentence?
- A. The students planted a garden behind the gym, starting with one raised bed.
- B. The students planted a garden behind the gym, they started with one raised bed.
- C. The students planted a garden behind the gym, but starting with one raised bed.
- D. Starting with one raised bed, a garden behind the gym was planted by the students.
Voir la réponse et l'explication
Réponse : A. The students planted a garden behind the gym, starting with one raised bed.
The first choice keeps the meaning and puts the describing phrase right next to the students it describes. The second is a comma splice, the third adds a but that makes no sense here, and in the fourth the opening phrase seems to describe the garden, not the students.
9. A recipe uses 3 cups of flour for every 2 cups of sugar. Which amounts keep the same ratio of flour to sugar? Select all that apply.
Coche toutes les bonnes réponses.
- A. 6 cups of flour and 4 cups of sugar
- B. 4.5 cups of flour and 3 cups of sugar
- C. 9 cups of flour and 5 cups of sugar
- D. 5 cups of flour and 4 cups of sugar
- E. 1.5 cups of flour and 1 cup of sugar
Voir la réponse et l'explication
Réponse : A. 6 cups of flour and 4 cups of sugar, B. 4.5 cups of flour and 3 cups of sugar, E. 1.5 cups of flour and 1 cup of sugar
Multiply or divide both amounts by the same number. Doubling gives 6 and 4, multiplying by 1.5 gives 4.5 and 3, and halving gives 1.5 and 1. For 9 cups of flour you would need 6 cups of sugar, not 5, and 5 to 4 is a different ratio from 3 to 2.
10. A cyclist rides 18 miles in 1.5 hours at a steady speed. At this rate, how many minutes will it take to ride 30 miles?
- A. 120
- B. 150
- C. 180
- D. 250
Voir la réponse et l'explication
Réponse : B. 150
The speed is 18 divided by 1.5, which is 12 miles per hour. Then 30 miles takes 30 divided by 12, or 2.5 hours, and 2.5 hours is 150 minutes. The answer 250 comes from reading 2.5 hours as 250 minutes, and 120 and 180 are just whole numbers of hours.
11. Complete the solution.
A rectangle's length is 3 more than twice its width, and its perimeter is 36 units. Its width is _____ units.
Options pour le trou 1 : 4, 5, 6, 7
Voir la réponse et l'explication
Réponse : 5
Call the width w, so the length is 2w + 3. The perimeter is 2 times the sum of the sides: 2(w + 2w + 3) = 36, so 6w + 6 = 36 and w = 5. Check: the length is 13, and 2 times 5 plus 2 times 13 is 36.
12. Complete the sentence.
Mina has $40. A notebook costs $9 and each pen costs $2.50. After buying the notebook, she can buy at most _____ pens.
Options pour le trou 1 : 10, 11, 12, 13
Voir la réponse et l'explication
Réponse : 12
After the notebook she has 40 - 9 = $31. The inequality 2.50p ≤ 31 gives p ≤ 12.4, and she cannot buy part of a pen, so the most is 12. Rounding up to 13 would cost $32.50, which is more than she has.
13. A set of six numbers is 2, 3, 3, 5, 7 and 16. Which statements are true? Select all that apply.
Coche toutes les bonnes réponses.
- A. The mean is 6.
- B. The median is 4.
- C. The mode is 5.
- D. The range is 14.
- E. The median is greater than the mean.
Voir la réponse et l'explication
Réponse : A. The mean is 6., B. The median is 4., D. The range is 14.
The numbers add up to 36, and 36 divided by 6 is 6. With six numbers the median is the average of the third and fourth, 3 and 5, which is 4. The range is 16 - 2 = 14. The mode is the most common value, 3, and the median of 4 is less than the mean of 6 because 16 pulls the mean up.
14. A fair number cube with faces 1 to 6 is rolled twice. What is the probability that the first roll is even and the second roll is greater than 4?
- A. 1/12
- B. 5/6
- C. 1/5
- D. 1/6
Voir la réponse et l'explication
Réponse : D. 1/6
The rolls do not affect each other, so multiply. An even first roll has probability 3/6, or 1/2, and a second roll of 5 or 6 has probability 2/6, or 1/3. Then 1/2 times 1/3 is 1/6. Adding 1/2 and 1/3 gives 5/6, which is the mistake of adding when the question asks for both.
15. A circular pool has a diameter of 12 feet. A walkway 2 feet wide goes all the way around the pool. What is the area of the walkway?
- A. 28π square feet
- B. 4π square feet
- C. 64π square feet
- D. 112π square feet
Voir la réponse et l'explication
Réponse : A. 28π square feet
The pool has a radius of 6 feet and the pool plus walkway has a radius of 8 feet. The walkway is the difference of the two circles: π times 64 minus π times 36, which is 28π. The 64π option is the whole outer circle, 4π squares only the width, and 112π uses diameters in place of radii.
Ce qu'est le SHSAT et qui le passe
Le Specialized High Schools Admissions Test, ou SHSAT, est l'examen que la ville de New York utilise pour décider de l'admission dans ses lycées spécialisés. NYC Public Schools le présente comme le seul critère, avec une exception : le LaGuardia High School recrute sur audition. Tout résident actuel de New York en 8th grade, ou en 9th grade pour la première fois, qui veut candidater dans l'un des autres lycées doit le passer, qu'il fréquente un établissement public, privé ou confessionnel. Il a lieu à l'automne pour une entrée en septembre suivant.
Le test comporte deux sections. L'anglais (ELA) couvre la révision et la correction, c'est-à-dire corriger et améliorer de courts textes, et la compréhension de lecture. Les maths couvrent les rapports et la proportionnalité, le système des nombres et les expressions, les équations, les inéquations, les statistiques et les probabilités, et la géométrie. NYC indique que les questions se présentent sous forme de choix multiple, de textes à trous et d'items technologiques, et que les élèves choisissent par quelle section commencer.
Le format évolue. NYC fait passer le test sur ordinateur, et sa page décrit un test adaptatif dès l'automne 2026, où les questions s'ajustent à tes réponses. Comme le matériel de préparation plus ancien peut ne pas correspondre, cette page n'indique ni nombre de questions, ni durée, ni score. La page SHSAT de NYC Public Schools sur schools.nyc.gov donne les chiffres en vigueur, ainsi que les lieux et les dates de passation.
Comment utiliser cet échantillon
Les 15 questions suivent en miniature les domaines de contenu publiés. Les questions 1 à 4 portent sur la compréhension de lecture : une idée centrale, un mot en contexte, une inférence et les détails que soutient un texte. Les questions 5 à 8 portent sur la révision et la correction : une virgule qui sépare deux phrases à tort, une phrase qui n'a pas sa place, le temps des verbes et la fusion de deux phrases. Les questions 9 à 15 portent sur les maths : rapports, un taux, une équation, une inéquation, les statistiques, les probabilités et l'aire d'une couronne.
Les formats à réponses multiples et à textes à trous sont ici des formats d'entraînement qui t'obligent à vérifier chaque option au lieu de t'arrêter à la première qui semble juste. Le vrai test mélange ses propres types d'items, alors utilise le Student Readiness Tool de NYC et les tests d'entraînement officiels en ligne pour t'habituer à l'écran et aux outils, et un échantillon comme celui-ci pour avoir des questions supplémentaires sur les compétences.
Fais-le d'une traite et résous les maths sur papier avant de regarder les choix. Lis ensuite chaque explication, y compris pour les questions que tu as réussies. Un groupe d'erreurs est plus utile qu'une erreur isolée : si les questions sur les rapports et sur le taux sont toutes deux fausses, c'est le raisonnement proportionnel qu'il faut travailler.
Une précision honnête : l'équipe StudyPDF a écrit chaque question ici d'après les domaines de contenu que publie NYC. Aucune n'est un vrai item du SHSAT, aucune ne vient du NYC Guide to the SHSAT, des tests d'entraînement officiels ou du livre d'un éditeur de préparation, et StudyPDF n'est affilié ni à NYC Public Schools, ni à aucun des lycées.
Comment créer d'autres tests d'entraînement à partir de ton propre matériel
Quinze questions peuvent te montrer si la lecture, la correction ou les maths demandent le plus d'attention. Elles ne suffisent pas à te préparer, surtout si ta classe ou ton livre de préparation passe plus de temps sur un domaine que sur un autre.
StudyPDF part plutôt de ton matériel. Importe ton livre de préparation, tes notes de cours ou les exercices distribués par ton enseignant. Appuie ensuite sur Nouveau support, choisis un test d'entraînement, sélectionne ces fichiers comme sources et règle sa longueur. Tu obtiens un test écrit à partir de ces pages précises, et chaque explication cite d'où vient la réponse.
Bo est le tuteur pour le reste. Demande-lui pourquoi une réponse est juste et il t'explique à partir de tes propres pages, avec d'abord un indice si tu le veux.
Tu n'as rien à importer pour commencer. Nomme plutôt un sujet, par exemple les rapports ou les virgules qui séparent deux phrases à tort, et tu obtiens des questions d'entraînement dessus. Commencer est gratuit.
